Abstract

A positioning aid for a magnetic device used for positioning a shuttering means, the magnetic device being movable between a position of use, in which said magnetic device is in contact with a ferromagnetic shuttering support, and a position of non-use, in which said magnetic device is spaced apart from the shuttering support, said positioning aid comprising at least one retaining device relative to which the magnetic device is supported against a holding force of said magnetic device, and further comprising at least one elastic support unit for producing a lifting force against said holding force so as to hold the magnetic device in the position of non-use. In order to be able to provide such positioning aids with a more compact structural design and to use them more universally, the present invention is so conceived that the magnetic device is firmly connected to the retaining device and that, at least in the position of non-use, the support unit is arranged between the retaining device and the shuttering support, at least along certain sections thereof.

Description

Die vorliegende Erfindung bezieht sich auf eine Positionierhilfe mit einer Magneteinrichtung zum Positionieren einer Schalungseinrichtung, wobei die Magneteinrichtung zwischen einer Gebrauchsstellung, in der sich die Magneteinrichtung in Anlage mit einer ferromagnetischen Schalungsunterlage befindet, und einer Nichtgebrauchsstellung bewegbar ist, in der die Magneteinrichtung von der Schalungsunterlage beabstandet ist, mit zumindest einer Halteeinrichtung, gegenüber der sich die Magneteinrichtung entgegen einer Haltekraft der Magneteinrichtung abstützt und mit wenigstens einer federelastischen Stützeinrichtung zum Erzeugen einer Hebekraft entgegen der Haltekraft, um die Magneteinrichtung in der Nichtgebrauchsstellung zu halten.The present invention relates to a positioning aid having a magnet means for positioning a formwork means, the magnet means being movable between a use position in which the magnet means is in contact with a ferromagnetic formwork support and a non-use position in which the magnet means is spaced from the formwork support is, with at least one holding device against which the magnetic device is supported against a holding force of the magnetic device and with at least one resilient support means for generating a lifting force against the holding force to hold the magnetic device in the non-use position.

Eine derartige Positionierhilfe für Magneteinrichtungen zur Positionierung einer Schalungseinrichtung ist z. B. aus der EP 0 842 339 bekannt. Die Magneteinrichtung besteht hierbei aus einem Dauermagneten, der in einer Halteeinrichtung aufgenommen ist. Die Halteeinrichtung ist in Schalungsteile des Schalungssystems integriert und verfügt über einen den Magneten übergreifenden Abhebebügel, der auf der Schalungsunterlage aufsteht. Zwischen der Halteeinrichtung und der Magneteinrichtung befindet sich über der Magneteinrichtung eine Feder, die die Stützeinrichtung bildet und die Hebekraft auf den Magneten ausübt. In der Gebrauchsstellung befindet sich der Magnet in Anlage mit der ferromagnetischen Schalungsunterlage. Durch die Haltekraft des Magneten an der Schalungsunterlage wird ein Verrutschen des Magneten verhindert, so dass mit dem Magneten die Schalungsteile auf der Schalungsunterlage positioniert werden können. Die Haltekraft des Magneten überwindet dabei die Hebekraft der Feder. Soll der Magnet verschoben werden, erfolgt mittels einer Abdrückschraube ein Abheben des Magneten von der Schalungsunterlage. Sobald der Magnet von der Schalungsunterlage beabstandet ist, nimmt die vom Magneten auf die Schalungsunterlage ausgeübte Haltekraft stark ab. In der Nichtgebrauchsstellung, also bei angehobenem Magneten, ist die Hebekraft der Feder derart bemessen, dass sie die noch verbleibende Haltekraft zwischen Magnet und Schalungsunterlage und die Gewichtskraft des Magneten selbst überwindet, so dass der Magnet in der Nichtgebrauchsstellung verweilt. Die Positionierhilfe kann dann zu einem neuen Standort verschoben werden. Um die Positionierhilfe auf der Schalungsunterlage festzulegen, wird der Magnet zur Schalungsunterlage gedrückt, solange bis die Haltekraft und die Gewichtskraft des Magneten die Hebekraft der Feder überwinden und der Magnet selbsttätig in Anlage mit der Schalungsunterlage gelangt. Die Kraft zum Rücküberführen des Magneten aus seiner Nichtgebrauchsstellung in die Gebrauchsstellung kann z. B. durch einen Schlag auf die Haltevorrichtung erfolgen.Such a positioning aid for magnetic devices for positioning a formwork device is z. B. from EP 0 842 339. The magnetic device consists of a permanent magnet, which is received in a holding device. The holding device is integrated into formwork parts of the formwork system and has a magnet over the lifting hook, which rests on the formwork support. Between the holding device and the magnetic device is located above the magnetic device, a spring which forms the support means and exerts the lifting force on the magnet. In the position of use, the magnet is in contact with the ferromagnetic formwork underlay. Due to the holding force of the magnet on the formwork support slipping of the magnet is prevented, so that the formwork parts can be positioned on the formwork base with the magnet. The holding force of the magnet overcomes the lifting force of the spring. If the magnet is to be moved, the magnet is lifted off the shuttering pad by means of a jacking screw. Once the magnet is spaced from the formwork pad, the holding force exerted by the magnet on the formwork pad decreases sharply. In the non-use position, so with the magnet raised, the lifting force of the spring is such that it overcomes the remaining holding force between the magnet and shuttering pad and the weight of the magnet itself, so that the magnet dwells in the non-use position. The positioning aid can then be moved to a new location. To the positioning aid on the formwork support set, the magnet is pressed to the formwork support until the holding force and the weight of the magnet overcome the lifting force of the spring and the magnet automatically comes into contact with the formwork underlay. The force to return the magnet from its non-use position into the use position can, for. B. done by a blow to the fixture.

Die bekannte Positionierhilfe erweist sich als recht aufwendig, sowohl hinsichtlich ihres Raumbedarfes, als auch hinsichtlich ihrer Herstellungskosten. Zudem kann sie nicht flexibel eingesetzt werden, da das Einsatzgebiet durch den vorhandenen Magneten bestimmt wird. Sofern feinere Konturen mit den Schalungselementen auf der Schalungsunterlage begrenzt werden sollen, oder aber große Haltekräfte für größere Schalungselemente erforderlich sind, können die bekannten Positionierhilfen oftmals nicht eingesetzt werdenThe known positioning aid proves to be quite expensive, both in terms of their space requirements, as well as their production costs. In addition, it can not be used flexibly, since the application is determined by the existing magnet. If finer contours to be limited to the formwork elements on the formwork base, or large holding forces for larger formwork elements are required, the known positioning aids often can not be used

Aufgabe der Erfindung ist es daher, eine kostengünstige Lösung für Positionierhilfen bereitzustellen, die universell eingesetzt werden kann.The object of the invention is therefore to provide a cost-effective solution for positioning, which can be used universally.

Die Aufgabe der Erfindung wird dadurch gelöst, dass die Magneteinrichtung mit der Halteeinrichtung fest verbunden und die Stützeinrichtung zumindest in der Nichtgebrauchsstellung wenigstens abschnittsweise zwischen Halteeinrichtung und Schalungsunterlage angeordnet ist.The object of the invention is achieved in that the magnetic device firmly connected to the holding device and the support means is at least partially disposed between the holding device and shuttering support at least in the non-use position.

Diese Lösung ist einfach und hat den Vorteil, dass die Stützeinrichtung nicht mehr über der Magneteinrichtung angeordnet sein muss und dadurch die Positionierhilfe wesentlich flacher baut. Die Stützeinrichtung kann nunmehr seitlich an der Magneteinrichtung angebracht werden. Dadurch ist man auch nicht mehr durch die Gestaltung des Abhebebügels im Einsatzgebiet der Positionierhilfe beschränkt. Es ist somit möglich die Halteeinrichtung an die Abmessungen der Magneteinrichtung anzupassen.This solution is simple and has the advantage that the support device no longer has to be arranged above the magnetic device and thereby builds the positioning aid substantially flatter. The support device can now be attached to the side of the magnetic device. As a result, you are no longer limited by the design of the lift bar in the field of application of positioning. It is thus possible to adapt the holding device to the dimensions of the magnetic device.

Von Vorteil kann es dabei sein, wenn zumindest zwei voneinander beabstandete Halteeinrichtung vorgesehen sind, denen jeweils wenigstens eine Stützeinrichtung zugeordnet ist. Dadurch kann baukastenartig eine Anpassung der Halteeinrichtungen an die Magneteinrichtung unterschiedlicher Dimensionen vorgenommen werden.It may be advantageous if at least two spaced-apart holding device are provided, each of which is assigned at least one support means. As a result, an adaptation of the holding devices to the magnetic device of different dimensions can be made in a modular manner.

Hierbei kann es günstig sein, wenn die Halteeinrichtungen auf einander gegenüberliegenden Seiten der Magneteinrichtung angeordnet sind. Dadurch lässt eine gleichmäßige Abstützung der Magneteinrichtung realisieren.It may be advantageous if the holding devices are arranged on opposite sides of the magnetic device. This allows a uniform support of the magnetic device realize.

Auch kann es sich als vorteilhaft erweisen, wenn vier Halteeinrichtungen vorgesehen sind. Auch dadurch lässt sich eine gleichmäßige Abstützung der Magneteinrichtung realisieren. Bei einer in der Draufsicht im Wesentlichen viereckigen Magneteinrichtung lässt sich eine sehr gleichmäßige Abstützung der Magneteinrichtung an allen vier Seiten realisieren. Gerade bei sehr langen im Wesentlichen rechteckigen Magneteinrichtungen kann sich eine solche Gestaltung als vorteilhaft erweisen, um ein Verkannten zu vermeiden.It may also prove advantageous if four holding devices are provided. This also makes it possible to realize a uniform support of the magnetic device. In a substantially rectangular in plan view magnetic device can be a very uniform support of the magnetic device on all four sides realize. Especially with very long substantially rectangular magnetic devices, such a design may prove advantageous in order to avoid misaligned.

In einer vorteilhaften Weiterbildung der Erfindung können jeweils zwei Halteeinrichtungen einer Seite der Magneteinrichtung zugeordnet sein. Auch dadurch lässt sich eine gleichmäßige Abstützung der Magneteinrichtung realisieren. Die Halteeinrichtungen können hierbei nahe der Ecken einer in der Draufsicht viereckigen, bzw. rechteckigen Halteeinrichtung vorgesehen sein. Von Vorteil kann es dabei sein, wenn die Halteeinrichtungen an den längeren Seiten einer in der Draufsicht rechteckigen Magneteinrichtung angebracht sind.In an advantageous development of the invention, in each case two holding devices can be assigned to one side of the magnetic device. This also makes it possible to realize a uniform support of the magnetic device. The holding devices can in this case be provided near the corners of a quadrangular or rectangular holding device which is quadrangular in plan view. It may be advantageous if the holding devices are attached to the longer sides of a rectangular in plan view magnetic device.

Um die Montage und Anpassung der Halteeinrichtungen an die jeweiligen Magneteinrichtungen zu vereinfachen, können die Halteeinrichtungen über zugeordnete Verstellmechanismen beabstandbar miteinander verbunden sein. Dadurch lassen sich die Halteeinrichtungen leichter an die jeweiligen Magneteinrichtungen anpassen.In order to simplify the assembly and adaptation of the holding devices to the respective magnetic devices, the holding devices can be spaced apart by associated adjusting mechanisms. As a result, the holding devices can be more easily adapted to the respective magnetic devices.

Auch kann es sich als günstig erweisen, wenn zwei Halteeinrichtungen miteinander starr verbunden sind. Dadurch lässt sich eine stabilere Verbindung zwischen den Halteinrichtungen erzielen. Hierbei können jeweils zwei von vier Halteeinrichtungen starr miteinander verbunden sein, um dadurch zwei Halteelemente zu bilden.Also, it may prove to be beneficial if two holding devices are rigidly connected together. This makes it possible to achieve a more stable connection between the holding devices. In this case, each of two holding devices can be rigidly connected to each other, thereby forming two holding elements.

Auch kann es sich als günstig erweisen, wenn die Halteeinrichtungen mit den Verstelleinrichtungen einen die Magneteinrichtung umgebenden Halterahmen bilden. Auch dadurch lässt sich eine sichere Verbindung zwischen der Magneteinrichtung und Halteeinrichtung realisieren.It may also prove to be advantageous if the holding devices form a holding frame surrounding the magnetic device with the adjusting devices. This also makes it possible to realize a secure connection between the magnetic device and holding device.

Um die Austauschbarkeit von Halteeinrichtungen und Magneteinrichtung zu erleichtern, können die Halteeinrichtungen mit der Magneteinrichtung lösbar verbindbar sein.In order to facilitate the interchangeability of holding means and magnetic means, the holding means may be releasably connectable to the magnetic means.

Auch kann es sich als vorteilhaft erweisen, wenn die Magneteinrichtung im Wesentlichen quaderförmig mit einer der Schalungsunterlage zugewandten Unterseite ist. Bei solchen Magneteinrichtungen einfacher Geometrie lässt sich eine Anpassung der Halteeinrichtungen an die Magneteinrichtung leicht realisieren.It may also prove advantageous if the magnetic device is substantially parallelepiped with an underside facing the formwork support. In such simple geometry magnetic devices, an adaptation of the holding devices to the magnetic device can be easily realized.

Von Vorteil kann es auch sein, wenn die Halteeinrichtung an einer der Seitenwände der Magneteinrichtung anbringbar ist. Dadurch lässt sich eine besonders flach bauende Positionierhilfe realisieren.It may also be advantageous if the holding device can be attached to one of the side walls of the magnetic device. This makes it possible to realize a particularly flat positioning positioning aid.

In speziellen Anwendungsfällen kann es auch vorteilhaft sein, wenn die Halteeinrichtung an einer der Schalungsseite abgewandten Oberseite der Magneteinrichtung angebracht ist.In special applications, it may also be advantageous if the holding device is attached to an upper side of the magnetic device facing away from the formwork side.

Um die Montage der Halteeinrichtungen an der Magneteinrichtung zu erleichtern, können die Halteeinrichtungen Aufnahmen aufweisen, in die die Magneteinrichtung eingreift.In order to facilitate the mounting of the holding devices on the magnetic device, the holding devices may have receptacles into which the magnetic device engages.

Von Vorteil kann es dabei sein, wenn die Magneteinrichtung in die Aufnahmen einsteckbar ist. So können die Magneteinrichtungen und die Aufnahmen einfach ineinander gesteckt und z. B. durch einfache Madenschrauben gegeneinander gesichert werden. Dadurch ergibt sich eine deutlich vereinfachte Montage.It may be advantageous if the magnetic device can be inserted into the receptacles. Thus, the magnetic devices and the recordings are simply plugged into each other and z. B. secured by simple grub screws against each other. This results in a significantly simplified installation.

Zudem kann es sich als günstig erweisen, wenn die Halteeinrichtung mittels einer Schraubverbindung an der Magneteinrichtung angebracht ist. Dadurch kann auf einfache Weise eine sichere Verbindung zwischen der Magneteinrichtung und der Halteeinrichtung gewährleistet werden.In addition, it may prove to be advantageous if the holding device is attached by means of a screw connection to the magnetic device. As a result, a secure connection between the magnetic device and the holding device can be ensured in a simple manner.

In einer vorteilhaften Weiterbildung der Erfindung kann eine Abhebeeinrichtung vorgesehen sein, mittels derer die Magneteinrichtung von ihrer Gebrauchs- in die Nichtgebrauchsstellung überführbar ist. Dadurch lässt sich das Abheben der Magneteinrichtung erleichtern.In an advantageous development of the invention, a lifting device may be provided, by means of which the magnetic device from its use in the non-use position is convertible. As a result, the lifting of the magnetic device can be facilitated.

Von Vorteil kann es auch sein, wenn die Abhebeeinrichtung an der Magneteinrichtung angebracht ist. Dann ist es nicht erforderlich, die Abhebeeinrichtung an der Halteeinrichtung anzubringen, so dass die Halteeinrichtung einfacher gestaltet werden kann. Zudem kann die gesamte Positionierhilfe kompakter werden.It may also be advantageous if the lifting device is attached to the magnetic device. Then it is not necessary to attach the lifting device to the holding device, so that the holding device can be made simpler. In addition, the entire positioning aid can be more compact.

Eine besonders einfache, gleichwohl wirkungsvolle Abhebeeinrichtung lässt sich bereitstellen, wenn die Abhebeeinrichtung einen Exzenter aufweist, der zum Überführen der Magneteinrichtung von der Gebrauchsstellung in die Nichtgebrauchsstellung mit der Schalungsunterlage in Eingriff bringbar ist.A particularly simple, yet effective lifting device can be provided if the lifting device has an eccentric which can be brought into engagement with the formwork support for transferring the magnetic device from the use position into the non-use position.

Dabei kann es vorteilhaft sein, wenn ein Hebel zum Betätigen der Abhebeeinrichtung vorgesehen ist. Auch dadurch lässt sich eine sehr einfache Abhebeeinrichtung ermöglichen.It may be advantageous if a lever for actuating the lifting device is provided. This also makes it possible to enable a very simple lifting device.

Auch kann es dabei günstig sein, wenn der Hebel und der Exzenter fest miteinander verbunden an der Magneteinrichtung drehbar gelagert sind.It may also be beneficial if the lever and the eccentric are fixedly connected to each other rotatably mounted on the magnet device.

Ferner kann es sich als vorteilhaft erweisen, wenn der Exzenter näher an der Seite der Magneteinrichtung angeordnet ist, als an der dieser Seite gegenüberliegenden Seite. Dadurch wirkt der Exzenter beim Abheben der Magneteinrichtung asymmetrisch. Die zum Abheben aufzubringenden Kräfte lassen sich auf diese Weise reduzieren.Furthermore, it may prove advantageous if the eccentric is arranged closer to the side of the magnetic device than on the side opposite this side. As a result, the eccentric acts asymmetrically when lifting the magnetic device. The forces to be lifted can be reduced in this way.

In einer vorteilhaften Ausbildung der Erfindung kann die Stützeinrichtung zum Erzeugen der Hebekraft ein elastisches Federelement aufweisen. Dadurch lässt eine sehr einfache Stützeinrichtung realisieren.In an advantageous embodiment of the invention, the support means for generating the lifting force may comprise an elastic spring element. This makes it possible to realize a very simple support device.

In einer Ausführungsform kann das elastische Federelement eine Druckfeder sein. Druckfedern ermöglichen große Kräfte und sind kostengünstige Bauteile.In one embodiment, the elastic spring element may be a compression spring. Compression springs allow great forces and are cost-effective components.

Alternativ kann das elastische Federelement ein Elastomer aufweisen. Mit Elastomeren lassen sich sehr einfache und kostengünstige Federelemente realisieren.Alternatively, the elastic spring element may comprise an elastomer. With elastomers can be realized very simple and inexpensive spring elements.

In einer vorteilhaften Weiterbildung kann dabei das Elastomer ein Gummi sein. Auch damit lassen dauerhaft elastische und kostengünstige Federelemente realisieren.In an advantageous development, the elastomer may be a rubber. Even so, permanently elastic and inexpensive spring elements can be realized.

Alternativ kann das elastische Federelement eine Kunststofffeder aufweisen. Die Stützeinrichtung und die Halteeinrichtung kann dann gewichtsreduzierend gestaltet werden.Alternatively, the elastic spring element may comprise a plastic spring. The support device and the holding device can then be designed to reduce weight.

Eine besonders kompakte Bauweise der Positionierhilfe lässt sich erzielen, wenn das elastische Federelement ein Biegeblech ist, dessen Endabschnitt beim Überführen von der Nichtgebrauchsstellung in die Gebrauchsstellung durch Abgleiten an der Schalungsunterlage abgespreizt wird.A particularly compact design of the positioning can be achieved when the elastic spring element is a bending plate, the end portion is spread when passing from the non-use position to the use position by sliding on the formwork support.

In einer vorteilhaften Weiterbildung der Erfindung kann die Stützeinrichtung eine Aufstandseinrichtung aufweisen, die verschieblich in der Halteinrichtung gelagert und die zumindest in der Nichtgebrauchsstellung auf der Schalungsunterlage aufsteht, wobei die Federeinrichtung zwischen der Aufstandseinrichtung und der Stützeinrichtung aufgenommen ist. Auf diese Weise lässt sich die Stützeinrichtung in der Art einer Kolben-Zylinder-Einrichtung gestalten, wobei die Aufstandseinrichtung einen verschieblichen Kolben bildet.In an advantageous embodiment of the invention, the support means may comprise a rearing device which is slidably mounted in the holding device and which rests at least in the non-use position on the formwork support, wherein the spring means is received between the rearing device and the support means. In this way, the support means can be designed in the manner of a piston-cylinder device, wherein the Aufstandseinrichtung forms a displaceable piston.

Von Vorteil kann es dabei sein, wenn die Aufstandseihrichtung im Wesentlichen topfförmig ist und die Aufnahme der Halteeinrichtung zylindermantelförmig ist. Durch diese Gestaltung der Aufnahmeeinrichtung kann sie gleichzeitig als Führungselement für die Federeinrichtung dienen.It may be advantageous if the Aufstandsseihrichtung is substantially cup-shaped and the recording of the holding device is cylinder jacket-shaped. By this design of the receiving device, it can also serve as a guide element for the spring device.

Um die Betriebssicherheit zu erhöhen, kann die Aufstandsvorrichtung mit der Halteeinrichtung unverlierbar verbunden sein.To increase the reliability, the uprising device can be connected to the holding device captive.

Um möglichst gleichmäßige Stützkräfte zu erzielen, kann die Federkraft der Federeinrichtung einstellbar sein. Als vorteilhaft kann es sich dabei erweisen, wenn eine Stellschraube zum Einstellen der Federkraft vorgesehen ist. Dadurch ergibt sich eine einfache Verstellmöglichkeit. Auch ist denkbar, wenn die Federeinrichtung selbst ein Einstellgewinde aufweist. Dann kann durch Drehen der Federeinrichtung selbst die Einstellung vorgenommen werden. Entsprechend muss in der Halteinrichtung eine gewindeartig gestaltete Aufnahme vorgesehen sein.In order to achieve the most uniform support forces, the spring force of the spring device can be adjustable. It may turn out to be advantageous if an adjusting screw is provided for adjusting the spring force. This results in a simple adjustment. It is also conceivable if the spring device itself has a setting thread. Then by turning the spring device itself, the setting be made. Accordingly, a thread-like receptacle must be provided in the holding device.

In einer vorteilhaften Weiterbildung der Erfindung kann die Halteeinrichtung in die Magneteinrichtung integriert sein. Dadurch lässt sich eine besonders kompakte Bauweise der Positionierhilfe zusammen mit der Magneteinrichtung realisieren.In an advantageous development of the invention, the holding device can be integrated into the magnetic device. This makes it possible to realize a particularly compact construction of the positioning aid together with the magnetic device.

Dabei kann es sich als vorteilhaft erweisen, wenn die Halteeinrichtungen durch Bohrungen in der Magneteinrichtung gebildet werden. Dies ermöglicht eine sehr einfache Gestaltung der Halteeinrichtung.It may prove advantageous if the holding devices are formed by holes in the magnet device. This allows a very simple design of the holding device.

Von Vorteil kann es auch sein, wenn die Halteeinrichtung durch Kleben mit der Magneteinrichtung verbunden ist. Dadurch lässt sich eine besonders einfache und kostengünstige Konstruktion realisieren.It may also be advantageous if the holding device is connected by gluing with the magnetic device. As a result, a particularly simple and inexpensive construction can be realized.

Ebenso wird eine Schalungseinrichtung beansprucht mit einer erfindungsgemäßen Positionierhilfe.Likewise, a formwork device is claimed with a positioning aid according to the invention.

Von Vorteil kann es dabei sein, wenn die Schalungseinrichtung und die Halteeinrichtung einstückig ausgebildet sind. Dann kann die Halteeinrichtung zusammen mit der Schalungseinrichtung in einem Arbeitsgang hergestellt werden.It may be advantageous if the formwork device and the holding device are integrally formed. Then, the holding device can be produced together with the formwork device in one operation.

Zudem kann es günstig sein, wenn die Magneteinrichtung und die Schalungseinrichtung fest miteinander verbunden sind. Dadurch erhält man eine stabile und kompakte Bauweise von Schalungseinrichtung und Magneteinrichtung. Zudem lässt sich der Magnet sicher in der Schalungseinrichtung verankern.In addition, it may be advantageous if the magnetic device and the formwork device are firmly connected to each other. This gives a stable and compact design of shuttering and magnetic device. In addition, the magnet can be safely anchored in the formwork device.

Weiterhin kann es sich als vorteilhaft erweisen, wenn in der Nichtgebrauchsstellung die Schalungseinrichtung von der Schalungsunterlage beabstandet ist. Dann kann die Schalungseinrichtung problemlos auf einer Schalungsunterlage verschoben und eine vorgegebenen Position verbracht werden. Die Schalungseinrichtung ruht dann nur noch auf einer oder mehrerer Stützeinrichtungen.Furthermore, it may prove advantageous if, in the non-use position, the formwork device is spaced from the formwork support. Then the formwork device can be moved easily on a formwork support and a given position. The shuttering then rests only on one or more support means.

Um ein möglichst gutes Ergebnis der gefertigten Betonfertigteile zu erzielen, kann es sich als günstig erweisen, wenn in der Gebrauchsstellung die Schalungseinrichtung, bzw. die Halteeinrichtung auf der Schalungsunterlage aufliegt.In order to achieve the best possible result of the manufactured precast concrete parts, it may prove to be beneficial when in the position of use, the formwork device, or the holding device rests on the formwork base.

Nachfolgend wird die Erfindung anhand mehrerer Ausführungsbeispiele näher erläutert.The invention will be explained in more detail with reference to several embodiments.

Figur 1 zeigt die erfindungsgemäße Positionierhitfe 1 zusammen mit einer Magneteinrichtung 2, an der eine Abhebeeinrichtung 3 vorgesehen ist. Die Positionierhilfe 1 bildet zusammen mit der Magneteinrichtung 2 einen Baukasten und können zudem auch ein Schalungselement bilden.FIG. 1 shows the positioning means 1 according to the invention together with a magnetic device 2, on which a lifting device 3 is provided. The positioning aid 1 forms together with the magnetic device 2 a modular system and can also form a formwork element.

Die Magneteinrichtung 2 ist ein Dauermagnet von im Wesentlichen quaderförmiger Gestaltung mit einer im Wesentlichen ebenen Unterseite 4 und einer dazu parallelen Oberseite 5 und zwischen Oberseite und Unterseite rechtwinklig zueinander angeordneten Seitenflächen 6. In der Draufsicht ist die Magneteinrichtung im Wesentlich quadratisch.The magnetic device 2 is a permanent magnet of substantially parallelepiped-shaped design with a substantially planar underside 4 and a top 5 parallel thereto and side surfaces 6 arranged at right angles to each other between top and bottom. In the plan view, the magnetic device is substantially square.

In einer Gebrauchsstellung der Magneteinrichtung 2 befindet sich die Magneteinrichtung 2 mit ihrer Unterseite 4 in Anlage mit einer ferromagnetischen Schalungsunterlage 7.In a position of use of the magnetic device 2, the magnetic device 2 with its underside 4 is in contact with a ferromagnetic shuttering pad. 7

Die Gebrauchsstellung ist in Figur 2 dargestellt. In einer Nichtgebrauchsstellung sind Schalungsunterlage 7 und Unterseite 4 voneinander beabstandet, wie dies in Figur 1 dargestellt ist.The use position is shown in FIG. In a non-use position shuttering pad 7 and bottom 4 are spaced from each other, as shown in Figure 1.

An der Oberseite 5 findet sich eine stangenförmige Handhabungseinrichtung 8, mittels derer die Magneteinrichtung 2 auf der Schalungsunterlage 7 verschoben werden kann, sofern sich die Magneteinrichtung 2 in ihrer Nichtgebrauchsstellung befindet. Ebenso kann mit dieser Handhabungseinrichtung 8 die Magneteinrichtung 2 von ihrer Nichtgebrauchs- in die Gebrauchsstellung überführt werden.At the top 5 there is a rod-shaped handling device 8, by means of which the magnetic device 2 can be moved on the shuttering pad 7, if the magnetic device 2 is in its non-use position. Likewise, with this handling device 8, the magnetic device 2 can be transferred from its non-use to the use position.

An einer der Seitenflächen 6 der Magneteinrichtung 2 ist ein Lagerzapfen 9 vorgesehen, an dem schwenkbar ein Exzenter 10 mit einem daran angebrachten Hebel 11 drehbar gelagert ist. In der Darstellung in Figur 1 findet sich der Exzenter mit der Schalungsunterlage 7 in Eingriff, wobei durch Betätigen des Hebels 11 die Magneteinrichtung 2 von ihrer Gebrauchs- in ihre Nichtgebrauchsstellung überführbar ist. Wie insbesondere in der Darstellung in Figur 3 zu sehen ist, befindet sich der Lagerzapfen 9 näher am linken Ende der zugeordneten Seitenfläche 6, so dass der Exzenter im Wesentlichen in einer Ecke der Magneteinrichtung mit der Schalungsunterlage 7 in Eingriff bringbar ist.On one of the side surfaces 6 of the magnetic device 2, a bearing pin 9 is provided, on which an eccentric 10 is rotatably mounted with a lever 11 attached thereto pivotally. In the illustration in Figure 1, the eccentric is in engagement with the shuttering pad 7, wherein by pressing the lever 11, the magnetic device 2 from their use in their non-use position can be transferred. As can be seen in particular in the illustration in Figure 3, the bearing pin 9 is closer to the left end of the associated side surface 6, so that the eccentric is substantially in a corner of the magnetic device with the shuttering pad 7 is engageable.

An der Magneteinrichtung 2 sind weiterhin vier Halteeinrichtungen 12 angebracht, wobei jeweils zwei Halteeinrichtungen 12 einer Seitenfläche 6 zugeordnet sind. Die Halteeinrichtungen 12 sind dabei auf einander gegenüberliegenden Seiten der Magneteinrichtung 2 angeordnet. Die Halteeinrichtungen 12 können z.B. mittels einer nicht dargestellten Verschraubung oder durch Kleben an der Magneteinrichtung 2 angebracht werden. Insbesondere können die Halteeinrichtungen 12 lösbar mit der Magneteinrichtung 2 verbunden sein. Beim Betrieb der Positionierhilfe sind die Halteeinrichtungen 12 jedoch starr mit der Magneteinrichtung 2 verbunden.Four holding devices 12 are also attached to the magnetic device 2, two holding devices 12 each being assigned to one side surface 6. The holding devices 12 are arranged on opposite sides of the magnetic device 2. The holding devices 12 may be e.g. be attached by means of a screw, not shown, or by gluing to the magnetic device 2. In particular, the holding devices 12 can be detachably connected to the magnet device 2. During operation of the positioning aid, however, the holding devices 12 are rigidly connected to the magnet device 2.

Jede der Halteeinrichtungen 12 verfügt jeweils über eine Stützeinrichtung 13, die eine topfförmige Aufstandseinrichtung 14 und eine Federeinrichtung 15 aufweist. Die Aufstandseinrichtung 14 verfügt über eine zylindrische Außenfläche 16, die axial verschieblich in einer zylindrischen Innenfläche 17 der Halteeinrichtung 12 aufgenommen ist. Die Federeinrichtung 15 verfügt über ein elastomeres Federelement 18 aus Gummi, das an seinen beiden Enden jeweils Gewindebolzen 19 und 20 aufweist, wobei der Gewindebolzen 19 in einer Gewindebohrung 21 die Aufstandseinrichtung 14 und der Gewindebolzen 20 in einer Gewindebohrung 22 der Halteeinrichtung 12 aufgenommen ist. Dadurch sind Aufstandseinrichtung 14 und Federelement 18 unverlierbar mit der Halteeinrichtung 12 verbunden.Each of the holding devices 12 has in each case a support device 13, which has a cup-shaped rearing device 14 and a spring device 15. The rearing device 14 has a cylindrical outer surface 16, which is received in an axially displaceable manner in a cylindrical inner surface 17 of the holding device 12. The spring device 15 has an elastomeric spring element 18 made of rubber, which has threaded bolts 19 and 20 at its two ends, wherein the threaded bolt 19 in a threaded bore 21, the rearing device 14 and the threaded bolt 20 is received in a threaded bore 22 of the holding device 12. As a result, uprising device 14 and spring element 18 are captively connected to the holding device 12.

Figur 5 zeigt die Stützeinrichtung 13 in einem Zustand, in dem sich die Magneteinrichtung 2 in einer Nichtgebrauchsstellung befindet. Dadurch steht die Aufstandseinrichtung 14 mit der Auflagefläche 23 gegenüber der Halteeinrichtung 12 vor. Die Auflagefläche 23 liegt dabei auf der Schalungsunterlage 7 auf.FIG. 5 shows the support device 13 in a state in which the magnet device 2 is in a non-use position. As a result, the rearing device 14 projects with the support surface 23 with respect to the holding device 12. The support surface 23 rests on the shuttering pad 7.

In Figur 6 ist ein Zustand der Stützeinrichtung 13 dargestellt, in dem sich die Magneteinrichtung 2 in ihrer Gebrauchsstellung befindet. Die Federeinrichtung 15 ist bei der Gebrauchsstellung der Magneteinrichtung 2 komprimiert.FIG. 6 shows a state of the support device 13 in which the magnet device 2 is in its position of use. The spring device 15 is compressed in the position of use of the magnetic device 2.

Die Federeinrichtung 15 arbeitet als Druckfeder, erzeugt also eine Hebekraft, die der Haltekraft des Magneten in seiner Gebrauchsstellung entgegenwirkt. In der Gebrauchsstellung der Magneteinrichtung ist die Hebekraft jedoch deutlich geringer als die Haltekraft der Magneteinrichtung. Die Magneteinrichtung 2 liegt dadurch fest an der Schalungsunterlage 7 an. In der Nichtgebrauchsstellung ist die Magneteinrichtung 2 von der Schalungsunterlage 7 beabstandet, so dass die vom Magnet erzeugte Haltekraft erheblich reduziert wurde. Die von der Federeinrichtung 15 aufgebrachte Hebekraft ist dabei so bemessen, dass in der Nichtgebrauchsstellung der Schalungsunterlage 7 die Hebekraft größer ist als die verbleibende Resthaltekraft der Magneteinrichtung 2 und der Gewichtskraft der Magneteinrichtung 2, so dass die Haltekraft ausreicht, um die Magneteinrichtung 2 in der Nichtgebrauchsstellung zu halten.The spring device 15 operates as a compression spring, thus generating a lifting force, which counteracts the holding force of the magnet in its position of use. In the position of use of the magnetic device, however, the lifting force is significantly lower than the holding force of the magnetic device. The magnetic device 2 is thereby firmly against the shuttering pad 7. In the non-use position, the magnetic device 2 is spaced from the shuttering pad 7, so that the holding force generated by the magnet has been significantly reduced. The lifting force applied by the spring device 15 is dimensioned such that in the non-use position of the shuttering pad 7, the lifting force is greater than the remaining residual holding force of the magnetic device 2 and the weight of the magnetic device 2, so that the holding force is sufficient to the magnetic device 2 in the non-use position to keep.

Die Federeinrichtung kann auch so gestaltet sein, dass in der Nichtgebrauchsstellung nur die Aufstandseinrichtung gegenüber der Unterseite der Magneteinrichtung vorsteht und die Federeinrichtung oberhalb der Unterseite der Magneteinrichtung endet. Dadurch ist die Federeinrichtung nur seitlich der Magneteinrichtung angeordnet. Es ist jedoch bevorzugt, dass auch die Federeinrichtung unterhalb der Unterseite der Magneteinrichtung in der Nichtgebrauchsstellung endet. Dadurch ergibt sich die kompaktere Bauweise der erfindungsgemäßen Positionierhilfe.The spring device can also be designed so that in the non-use position only the rearing device protrudes from the underside of the magnetic device and the spring device ends above the underside of the magnetic device. As a result, the spring device is arranged only laterally of the magnetic device. However, it is preferred that also the spring device ends below the underside of the magnetic device in the non-use position. This results in the more compact design of the positioning according to the invention.

Nachfolgend wird die Wirkungs- und Funktionsweise der Erfindung näher erläutert:The mode of action and mode of operation of the invention will be explained in more detail below:

Zum Erzeugen einer Schalung mit Schalungselementen wird die Positionierhilfe zusammen mit der Magneteinrichtung 2 auf der Schalungsunterlage 7 an die gewünschte Stelle verschoben, wobei sich die Magneteinrichtung 2 in der Nichtgebrauchsstellung befindet. Sobald die gewünschte Position erreicht ist, wird eine Druckkraft in Richtung auf die Schalungsunterlage 7 auf die Handhabungseinrichtung 8 aufgebracht, wobei diese Druckkraft die Haltekraft überwindet und die Magneteinrichtung 2 zusammen mit der Halteeinrichtung von ihrer Nichtgebrauchsstellung in ihre Gebrauchsstellung überführt wird. Dabei werden die Federelemente 18 in der Federeinrichtung 15 komprimiert. Die Schalelemente können dann mit der Positionierhilfe oder Magneteinrichtung 2 verbunden werden, um die Schalung fertig zu stellen.To produce a formwork with formwork elements, the positioning aid is moved together with the magnetic device 2 on the formwork support 7 to the desired location, wherein the magnetic device 2 is in the non-use position. As soon as the desired position is reached, a pressure force is applied in the direction of the formwork support 7 on the handling device 8, wherein this pressure force overcomes the holding force and the magnet device 2 is transferred together with the holding device from its non-use position to its position of use. In this case, the spring elements 18 are compressed in the spring device 15. The formwork elements can then be connected to the positioning aid or magnet device 2 in order to finish the formwork.

Zum Ablösen wird der Hebel 11 betätigt, um den Exzenter 10 zu verdrehen, so dass dieser mit der Schalungsunterlage 7 in Eingriff gelangt. Durch Bewegen des Hebels in den Darstellungen in Figur 1 und 2 entgegen dem Uhrzeigersinn erzeugt der Exzenter 10 eine Abdrückkraft, die die Magneteinrichtung von der Schalungsunterlage 7 löst. Da die Haltekraft überproportional stark abnimmt mit dem Abstand der Magneteinrichtung von der Schalungsunterlage 7, erweist es sich als wirkungsvoll, mit der Abhebeeinrichtung 3 zunächst eine Ecke der Magneteinrichtung 2 anzuheben. Dadurch sinkt die Haltekraft des Magneten erheblich, so dass die Hebekraft der Federeinrichtungen ausreicht, um die Magneteinrichtung 2 von ihrer Gebrauchsstellung in die Nichtgebrauchsstellung zu überführen. Die Positionierhilfe 1 kann dann zusammen mit der Magneteinrichtung 2 an eine andere Stelle auf der Schalungsunterlage 7 verschoben werden. Hierbei kann eine Bedienperson die Positionierhilfe 1 über die Handhabungseinrichtung 8 handhaben.To release the lever 11 is actuated to rotate the eccentric 10 so that it comes with the shuttering pad 7 into engagement. By moving the lever in the illustrations in Figures 1 and 2 in the counterclockwise direction of the eccentric 10 generates a Abdrückkraft that solves the magnetic device of the shuttering pad 7. Since the holding force decreases disproportionately strong with the distance of the magnetic device of the shuttering pad 7, it proves to be effective to first raise a corner of the magnetic device 2 with the lifting device 3. As a result, the holding force of the magnet decreases significantly, so that the lifting force of the spring means is sufficient to transfer the magnetic device 2 from its position of use in the non-use position. The positioning aid 1 can then be moved together with the magnetic device 2 to another location on the formwork support 7. In this case, an operator can handle the positioning aid 1 via the handling device 8.

Aufgrund der Gestaltung der Halteeinrichtungen 12 lässt sich die Positionierhilfe sehr kompakt gestalten. Zudem bietet die Halteeinrichtung 12 aufgrund ihrer glattflächigen Gestaltung eine für den Bediener leicht erkennbare Positionierhilfe. So befindet sich die Unterkante der Halteeinrichtung 12 bei Nichtgebrauchsstellung der Magneteinrichtung 2 nur wenig über der Schalungsunterlage 7, so dass eine genaue Positionierung und Ausrichtung der Positionierhilfe und so mit der Magneteinrichtung 2 z.B. entlang einer vorgegebenen Linie möglich ist. Da mehrere einzelne Halteeinrichtungen 12 vorgesehen sind, können die Halteeinrichtungen an Magneteinrichtungen 2 unterschiedlicher Dimensionen angebracht werden. Es ist denkbar, bei einer größeren Magneteinrichtung 2 mehrere Halteeinrichtungen 12 vorzusehen. Auch ist es denkbar, die Halteeinrichtungen 12 an unterschiedlichen Stellen der Magneteinrichtung 2 anzubringen, sofern dies aufgrund der vorgegebenen Raumverhältnisse erforderlich sein sollte. Die Halteeinrichtungen 12 können somit weiter voreinander beabstandet oder aber mit geringerem Abstand zueinander an der Magneteinrichtung angebracht werden. Es ist daher möglich, einen Baukasten zu schaffen, der aus Magneteinrichtungen 2 unterschiedlicher Dimensionen und Stärken und mehreren Halteeinrichtungen 12 besteht. Die Positionierhilfe kann dann individuell gestaltet werden.Due to the design of the holding devices 12, the positioning aid can be made very compact. In addition, the holding device 12, due to its smooth-surfaced design, provides a positioning aid that is easily recognizable to the operator. Thus, when the magnetic device 2 is not in use, the lower edge of the holding device 12 is only slightly above the formwork support 7, so that accurate positioning and alignment of the positioning aid and thus with the magnetic device 2, for example, along a predetermined line is possible. As several individual holding devices 12 are provided are, the holding devices can be attached to magnetic devices 2 of different dimensions. It is conceivable to provide a plurality of holding devices 12 in the case of a larger magnet device 2. It is also conceivable to attach the holding devices 12 at different points of the magnetic device 2, if this should be necessary due to the given space conditions. The holding devices 12 can thus be further spaced from each other or at a smaller distance from each other attached to the magnetic device. It is therefore possible to provide a kit consisting of magnetic devices 2 of different dimensions and thicknesses and a plurality of holding devices 12. The positioning aid can then be designed individually.

Nachfolgend wird anhand der Figuren 7 und 8 eine zweite Ausführungsform der Erfindung näher erläutert. Um Wiederholungen zu vermeiden, werden gleiche Elemente mit gleichen Bezugszeichen gekennzeichnet und nur die Unterschiede zur ersten Ausführungsform erläutert.Hereinafter, a second embodiment of the invention will be explained in more detail with reference to FIGS 7 and 8. To avoid repetition, the same elements are identified by the same reference numerals and only the differences from the first embodiment are explained.

Bei der zweiten Ausführungsform werden anstelle der Federelemente 18 Druckfedern 24 aus Stahl oder Kunststoff verwendet. In Figur 7 wird die Halteeinrichtung mit der Stützeinrichtung gezeigt, wenn sich die Magneteinrichtung 2 in der Nichtgebrauchsstellung befindet. In Figur 8 befindet sich die Magneteinrichtung 2 in der Gebrauchsstellung, so dass die Druckfedern 24 komprimiert sind. Die Aufstandseinrichtung 14 verfügt über einen Deckel 25 mit einer Bohrung 26, durch die sich ein Stößel 27 mit einem Anschlag 28 hindurch erstreckt. Mittels einer Verschraubung ist der Stößel 27 an der Halteeinrichtung 12 fest angebracht. Der Anschlag 28 verhindert zusammen mit dem Deckel 25, dass sich die Aufstandseinrichtung 14 von der Halteeinrichtung 12 löst.In the second embodiment, instead of the spring elements 18, compression springs 24 made of steel or plastic are used. In Figure 7, the holding device is shown with the support means when the magnetic device 2 is in the non-use position. In Figure 8, the magnetic device 2 is in the position of use, so that the compression springs 24 are compressed. The rearing device 14 has a cover 25 with a bore 26 through which a plunger 27 extends with a stop 28 therethrough. By means of a screw the plunger 27 is fixedly attached to the holding device 12. The stopper 28, together with the cover 25, prevents the rearing device 14 from coming off the holding device 12.

In den Figuren 9, 10 und 11 ist eine dritte Ausführungsform der Erfindung beschrieben. Auch hier werden gleiche Bauteile mit gleichen Bezugszeichen versehen, um Wiederholungen zu vermeiden. Es werden lediglich die Unterschiede erläutert.A third embodiment of the invention is described in FIGS. 9, 10 and 11. Again, the same components are provided with the same reference numerals to avoid repetition. Only the differences are explained.

Im Gegensatz zur ersten Ausführungsform besteht die Halteeinrichtung 12 bei der dritten Ausführungsform aus plattenförmigen Elementen 29, die an der Magneteinrichtung 2 angebracht sind, zwischen denen ein sich vertikal in Richtung zur Schalungsunterlage 7 erstreckendes Federblech 30 aufgenommen ist. Wie anhand der Figuren 10 und 11 erkennbar ist, werden Entabschnitte 31 der Federbleche beim Überführen der Magneteinrichtung von ihrer Nichtgebrauchsstellung in die Gebrauchsstellung gemäß Figur 10 seitlich abgespreizt. Durch diese Verformung erzeugen sie die erforderliche Hebekraft. Die Endabschnitte 31 gleiten dabei auf der Schalungsunterlage 7 ab. In der Nichtgebrauchsstellung stütz sich die Halteeinrichtung jeweils über die Endabschnitte 31 der Federbleche 30 an der Schalungsunterlage 7 ab.In contrast to the first embodiment, the holding device 12 in the third embodiment consists of plate-shaped elements 29, which are attached to the magnetic device 2, between which a vertically extending towards the shuttering pad 7 spring plate 30 is received. As can be seen with reference to FIGS. 10 and 11 is Entabschnitte 31 of the spring plates when transferring the magnetic device from its non-use position in the use position shown in FIG 10 laterally spread. By this deformation they produce the necessary lifting power. The end portions 31 slide on the shuttering pad 7. In the non-use position, the holding device supports in each case via the end portions 31 of the spring plates 30 on the shuttering pad 7.

Eine solche Gestaltung der Federelemente erlaubt eine sehr kostengünstige Konstruktion.Such a design of the spring elements allows a very cost-effective design.

In den Figuren 12, 13, 14 und 15 ist eine vierte Ausführungsform der Erfindung dargestellt. Die Wirkungsweise entspricht der ersten Ausführungsform. Auch die Federelemente sind in gleicher Weise gestaltet. Im Gegensatz zur ersten Ausführungsform sind jedoch zwischen jeweils zwei Halteeinrichtungen 12 Verbindungsplatten 32 und 33 vorgesehen, die jeweils zwei Halteeinrichtungen 12 miteinander verbinden. Eine Kombination aus Verbindungsplatten 32, 33 und Halteeinrichtungen 12 bildet dabei ein Halteelement 34. Wie in Figur 15 dargestellt, können zur Montage die beiden Halteelemente 34 seitlich auf die Magneteinrichtung 2 aufgeschoben werden. Durch Madenschrauben 35, die jeweils in Gewindebohrungen 36 eingeschraubt werden, können die Halteelemente 34 kraftschlüssig an der Magneteinrichtung 2 angebracht werden. Die beiden Halteeinrichtungen 12 umschließen dabei zusammen mit den Verbindungsplatten 32 und 33 die Endabschnitte der Magneteinrichtung 2 im Wesentlichen U-förmig.FIGS. 12, 13, 14 and 15 show a fourth embodiment of the invention. The mode of action corresponds to the first embodiment. The spring elements are designed in the same way. In contrast to the first embodiment, however, between each two holding devices 12 connecting plates 32 and 33 are provided, each connecting two holding devices 12 together. A combination of connecting plates 32, 33 and holding devices 12 forms a holding element 34. As shown in FIG. 15, the two holding elements 34 can be pushed laterally onto the magnetic device 2 for mounting purposes. By grub screws 35, which are each screwed into threaded holes 36, the holding elements 34 can be attached to the magnetic device 2 with a force fit. The two holding devices 12, together with the connecting plates 32 and 33, enclose the end sections of the magnetic device 2 in a substantially U-shaped manner.

In den Figuren 16 und 17 ist eine fünfte Ausführungsform dargestellt, die ebenfalls über Halteelemente 34 verfügt, bei denen jedoch anstelle von Verbindungsplatten Haltestege 37 jeweils zwei Halteeinrichtungen 12 miteinander verbinden. Eine zusätzliche Befestigungsplatte 38 erstreckt sich abschnittsweise entlang der Oberseite 5 der Magneteinrichtung 2 und kann über eine Bohrung 39 und eine Schraube 40 mit der Magneteinrichtung 2 verbunden werden. Die Schraube 40 befindet sich dabei an der Oberseite 5 der Magneteinrichtung 2. Aufgrund der Gestaltung des Haltestegs 37 und der Halteeinrichtungen 12 liegt das Halteelement 34 flächig an der zugeordneten Seitenfläche 6 der Magneteinrichtung 2 an.In the figures 16 and 17, a fifth embodiment is shown, which also has retaining elements 34, in which, however, instead of connecting plates holding webs 37 each two holding devices 12 interconnect. An additional mounting plate 38 extends in sections along the upper side 5 of the magnetic device 2 and can be connected via a bore 39 and a screw 40 with the magnetic device 2. The screw 40 is located on the upper side 5 of the magnetic device 2. Due to the design of the holding web 37 and the holding devices 12, the holding element 34 lies flat against the associated side surface 6 of the magnetic device 2.

Als Federelemente kommen hier ebenfalls Druckfedern zum Einsatz.As spring elements here also compression springs are used.

Die Figuren 18 und 19 stellen eine sechste Ausführungsform der Erfindung dar. Bei dieser Ausführungsform ist die Halteeinrichtung 12 in die Magneteinrichtung 2 integriert. Sie wird gebildet durch Sackbohrungen 41, in denen jeweils die Stützeinrichtungen 13 aufgenommen sind. Dadurch ergibt sich eine zusätzliche kompakte Gestaltung der Kombination aus Magneteinrichtung und Positionierhilfe. Alternativ ist bei Verwendung einer schichtartig aufgebauten Magneteinrichtung denkbar, eine der sich vertikal und in Längsrichtung erstreckenden Schichten teilweise zu durchbrechen, um dadurch Aufnahmen für die Stützeinrichtung zu bilden.FIGS. 18 and 19 illustrate a sixth embodiment of the invention. In this embodiment, the holding device 12 is integrated in the magnet device 2. It is formed by blind holes 41, in each of which the support means 13 are received. This results in an additional compact design of the combination of magnetic device and positioning aid. Alternatively, when using a layered magnetic device, it is conceivable to partially break one of the layers extending vertically and in the longitudinal direction, in order to thereby form receptacles for the support device.

In den Figuren 20, 21 und 22 ist eine siebte Ausführungsform der Erfindung dargestellt, deren Wirkungs- und Funktionsweise im Wesentlichen der der dritten Ausführungsform entspricht. Aus diese Ausführungsform verfügt über Federbleche 30. Als Halteelement dienen bei dieser Ausführungsform jedoch Schrauben 42, mit denen die Federbleche an der Magneteinrichtung 2 angebracht sind.In the figures 20, 21 and 22, a seventh embodiment of the invention is shown, whose operation and operation substantially corresponds to that of the third embodiment. From this embodiment has spring plates 30. However, serve as a holding element in this embodiment screws 42, with which the spring plates are attached to the magnetic device 2.

Die Figuren 23 und 24 zeigen eine achte Ausführungsform der Erfindung. Bei der dieser Ausführungsform sind mehrere Halteeinrichtungen integral mit einer Schalungseinrichtung 41 ausgebildet. In der Darstellung in Figur 23 handelt es sich um eine Schnittdarstellung, bei der zwei der Halteelemente sichtbar sind. Die Schalungseinrichtung ist im Wesentlichen quaderförmig mit Schalungsseiten 42 und einer die beiden Schalungsseiten 42 verbindenden Deckseite 43. In einer Magnetaufnahme 44 ist die Magneteinrichtung 2 aufgenommen. In der dargestellten Ausführungsform ist die Magneteinrichtung 2 mit der Magnetaufnahme 44 verklebt. Die Unterseite 4 der Magneteinrichtung 2 schließt bündig mit den Halteeinrichtungen, bzw. der Schalungseinrichtung 41 ab. Die Konstruktion der Stützeinrichtungen 13 entspricht z. B. der Konstruktion der ersten Ausführungsform. Die alternativ beschriebenen Ausführungsformen sind ebenfalls möglich.Figures 23 and 24 show an eighth embodiment of the invention. In this embodiment, a plurality of holding devices are integrally formed with a formwork device 41. The illustration in FIG. 23 is a sectional view in which two of the holding elements are visible. The formwork device is substantially parallelepiped-shaped with formwork sides 42 and a cover side 43 connecting the two formwork sides 42. The magnet device 2 is accommodated in a magnet receptacle 44. In the illustrated embodiment, the magnetic device 2 is glued to the magnet holder 44. The bottom 4 of the magnetic device 2 is flush with the holding devices, or the formwork device 41 from. The construction of the support means 13 corresponds to z. Example, the construction of the first embodiment. The alternative described embodiments are also possible.

In der Gebrauchsstellung liegt die Magneteinrichtung 4 mit ihrer Unterseite und die Halteeinrichtungen, bzw. die Schalungseinrichtung auf der Schalungsunterlage auf. In der Nichtgebrauchsstellung stützt sich die Schalungseinrichtung somit lediglich über die Stützeinrichtungen 13 ab. Dadurch sind die Schalungsseiten 42 von der Schalungsunterlage beabstandet. In der beschriebenen Ausführungsform können z. B. vier Stützeinrichtungen an jeder Ecke der im Wesentlichen quaderförmigen Schalungseinrichtung vorgesehen sein. Dadurch kann die Schalungseinrichtung einfach und schnell an die gewünschte Position gebracht werden. An der gewünschten Position senkt sie sich dann zusammen mit der Magneteinrichtung ab, die fest in der Schalungseinrichtung gehalten ist. Dadurch liegen in der Gebrauchsstellung auch die Schalungsseiten auf der Schalungsunterlage auf. Zum Lösen kann eine nicht dargestellte Abhebeeinrichtung, wie z. B. ein Exzenter vorgesehen sein. Dieser Exzenter kann z. B. mittig aus der Unterseite 4 der Magneteinrichtung 2 hervorragen und in bekannter Weise über einen Hebel, der sich durch die Schalungseinrichtung hindurch erstreckt, betätigbar sein. Dadurch können die beiden Schalungsseiten 42 jeweils zum Herstellen von Schalungen benutzt werden.In the position of use, the magnetic device 4 lies with its underside and the holding devices or the formwork device on the formwork underlay. In the non-use position, the formwork device is thus supported only via the support means 13. As a result, the shuttering sides 42 are spaced from the shuttering pad. In the described embodiment, for. B. four support means at each corner of the substantially cuboid formwork device be provided. As a result, the formwork device can be easily and quickly brought to the desired position. At the desired position, it then descends together with the magnetic device, which is held firmly in the formwork device. As a result, in the position of use, the formwork sides are also on the formwork support. To release an unillustrated lifting device, such. B. an eccentric can be provided. This eccentric can z. B. centrally from the bottom 4 of the magnetic device 2 protrude and be actuated in a known manner via a lever which extends through the formwork device. As a result, the two formwork sides 42 can each be used for the production of formwork.

Die Figuren 25 und 26 zeigen vergrößerte Darstellungen der Halteinrichtung und der Stützeinrichtung, wie sie z. B. in einer Ausführungsform gemäß Figur 1 zum Einsatz kommen könnte. Zusätzlich ist dort eine Stellschraube 45 vorgesehen, deren Unterseite 46 mit der Feder 24 verklebt ist. Die Stellschraube 45 ist in einem Stellgewinde 47 drehbar und verstellbar aufgenommen. Durch Verdrehen der Stellschraube kann die Vorspannung der Feder 24 verändert werden. Hierzu ist die Aufstandseinrichtung 14 ebenfalls unverlierbar in der Halteeinrichtung aufgenommen. Durch Drehen der Stellschraube 45 kann der Abstand zwischen der Unterseite und der Stellschraube 46 und der Aufstandsfläche variiert werden, so dass die Vorspannung der Feder 24 sich ändert. In der Darstellung in Figur 26 ist gut zu erkennen, dass in der Gebrauchsstellung ein geringfügiger Spalt zwischen der Halteeinrichtung und der Schalungsunterlage verbleibt. Da die Magneteinrichtung vollständig aufliegt, lässt sich eine Überbestimmung der Auflage von Magnet und Halteeinrichtung vermeiden.Figures 25 and 26 show enlarged views of the holding device and the support device, as z. B. could be used in an embodiment according to FIG. In addition, there is provided an adjusting screw 45 whose underside 46 is glued to the spring 24. The adjusting screw 45 is rotatably and adjustably received in an adjusting thread 47. By turning the adjusting screw, the bias of the spring 24 can be changed. For this purpose, the riot device 14 is also received captive in the holding device. By turning the set screw 45, the distance between the bottom and the set screw 46 and the footprint can be varied so that the bias of the spring 24 changes. In the illustration in FIG. 26, it can easily be seen that in the position of use a slight gap remains between the holding device and the formwork support. Since the magnetic device rests completely, an over-determination of the support of magnet and holding device can be avoided.

In den Figuren 27 und 28 ist eine weitere Ausführungsform der Halteeinrichtung und der Stützeinrichtung entsprechend der Darstellung in den Figuren 25 und 26 abgebildet. Bei dieser Ausführungsform verfügt die Feder 24 über endseitige Gewindeabschnitte 48, die jeweils in Gewinde 49 und 50 in der Halteeinrichtung und der Aufstandseinrichtung 14 eingeschraubt sind. Durch Drehen der Aufstandseinrichtung 14 kann ebenfalls der Abstand zwischen Aufstandseinrichtung 14 und der Halteeinrichtung 12 variiert und somit die Vorspannung der Feder variiert werden.FIGS. 27 and 28 depict a further embodiment of the holding device and the support device as shown in FIGS. 25 and 26. In this embodiment, the spring 24 has end-side threaded portions 48, which are respectively screwed into threads 49 and 50 in the holding device and the rearing device 14. By rotating the rearing device 14, the distance between the rearing device 14 and the holding device 12 can also be varied and thus the bias of the spring can be varied.
