Description

Die Erfindung betrifft ein Gerät zum Abziehen und Glätten der Oberfläche von Böden, die mit Bindemitteln insbesondere unter Verwendung von Kunststoffen als Bindemittel hergestellt werden.The invention relates to a device for peeling and smoothing the surface of floors, which are produced with binders, in particular using plastics as binders.

Bekannt ist ein von zwei Personen gezogenes Gerät, das zwei hintereinander angeordnete Bohlen aufweist, die parallel und gegenläufig zueinander verschiebbar sind, wobei die Bohlen durch um je einen Zapfen schwenkbare, mit den Bohlen ein Lenkparallelogramm bildende Lenker miteinander verbunden sind und einen oszillierenden Antrieb aufweisen, und die vorne liegende Bohle als Abziehbohle und die dahinter liegende Bohle als Gleitbohle ausgebildet ist. Das bekannte Gerät ist nur als handbetätigtes Gerät verwendbar, und zwar erfolgt die Benutzung in der Regel unter Verwendung von Lenkern, die an ihren Enden einen Handgriff aufweisen. Auch ist es mit dem bekannten Gerät nicht möglich, die Schichthöhe des Belages vorher genau einzustellen. Die Schichthöhe muß vielmehr durch durch vorher zu verlegende Lehren bestimmt werden. Obwohl das Gerät gegenüber dem Glätten von Hand wirtschaftlicher ist und einen geringeren Zeitaufwand benötigt, war es bisher noch nicht möglich, dieses Gerät mit einem maschinellen Antrieb zu betreiben.Known is a device pulled by two people, which has two planks arranged one behind the other, which can be moved parallel and in opposite directions to one another, the planks being connected to one another by links which can be pivoted about a pin and form a steering parallelogram with the planks and have an oscillating drive, and the screed in front is designed as a screed and the screed behind is designed as a screed. The known device can only be used as a hand-operated device, and is usually used using handlebars that have a handle at their ends. It is also not possible with the known device to precisely set the layer height of the covering beforehand. Rather, the layer height must be determined by means of teachings to be laid beforehand. Although the device is more economical compared to smoothing by hand and requires less time, it has not yet been possible to operate this device with a mechanical drive.

Die Aufgabe der Erfindung besteht darin, für das bekannte Gerät zum Abziehen und Glätten einen maschinellen-Antrieb vorzusehen und das Gerät selbst mit einstellbaren Mitteln auszustatten, um die Benutzung von Lehren zu vermeiden, den Arbeitsaufwand zu verringern und eine gleichmäßige Schichtdicke zu erreichen.The object of the invention is to provide a machine drive for the known device for peeling and smoothing and to equip the device itself with adjustable means in order to avoid the use of teachings, to reduce the workload and to provide an even layer to reach thick.

Die Erfindung ist gekennzeichnet durch die Verbindung mit einem als Antrieb dienenden Kettenfahrzeug, wobei zwischen dem Kettenfahrzeug und dem eigentlichen Gerät zum Abziehen und Glätten Spindeln als Verbindungsmittel vorgesehen sind, die eine freie lotrechte Bewegung des Gerätes zum Abziehen und Glätten in Bezug auf das Kettenfahrzeug zulassen und außerdem die Abziehbohle zwangsgeführt und die Glättbohle schwimmend angeordnet ist. Bei einer bevorzugten Ausführungsform der Erfindung ist das Gerät gekennzeichnet durch an einem Rahmen mittels einer Führung angeordnete Gewindespindeln, durch die das Gerät zum Abziehen und Glätten in Bezug auf das Kettenfahrzeug lotrecht verstellbar und lotrecht beweglich ist, die Gewindespindelh außerdem am unteren Ende gewindefrei ausgebildet sind und mit diesem Teil zur Führung des Gerätes zum Abziehen und Glätten mit lotrechter freier Bewegung dient.The invention is characterized by the connection to a track vehicle serving as a drive, spindles being provided as connection means between the track vehicle and the actual device for pulling and smoothing, which allow a free vertical movement of the device for pulling and smoothing in relation to the tracked vehicle and the screed is also positively guided and the screed is arranged in a floating manner. In a preferred embodiment of the invention, the device is characterized by threaded spindles arranged on a frame by means of a guide, by means of which the device for pulling off and smoothing is vertically adjustable and vertically movable with respect to the tracked vehicle, the threaded spindles are also designed thread-free at the lower end and with this part to guide the device for peeling and smoothing with vertical free movement.

Erfindungsgemäß ist die Abziehbohle an der Vorderkante mit einer genügend hohen Querleiste zum Verteilen und Abziehen des Materials versehen. Erfindungsgemäß ist ferner die Glättbohle am unteren Ende von Gewindespindeln angeordnet, die je eine durch eine Flügelmutter einstellbare Schraubenfeder aufweisen, durch die der Anpreßdruck der Glättbohle einstellbar ist. Durch die genannte Schraubenfeder und die Flügelmutter entsteht außerdem eine schwimmende Lagerung der Glättbohle, die auch einstellbar ist. Erfindungsgemäß sind ferner in beiden Endbereichen der Abziehbohle je eine Spindel vor und hinter der Abziehbohle angeordnet, die sich gegen Kufen abstützen, die an beiden Enden der Abziehbohle.angeordnet sind, um Unebenheiten des Bodens zu überbrücken.According to the screed is provided on the front edge with a sufficiently high cross bar for distributing and pulling the material. According to the invention, the screed is further arranged at the lower end of threaded spindles, each of which has an adjustable helical spring by a wing nut, by means of which the contact pressure of the screed can be adjusted. The mentioned coil spring and the wing nut also create a floating mounting of the screed, which is also adjustable. According to the invention, a spindle is arranged in front of and behind the screed in both end regions of the screed, which are supported against runners which are arranged at both ends of the screed to bridge unevenness in the floor.

Unter gewissen Umständen ist es vorteilhaft, die Bohlen etwas schräg zu stellen. Zur Durchführung einer Schrägstellung sind feststellbare Gelenke angeordnet, die die Möglichkeit bieten, jede Bohle für sich schräg einzustellen. Eine Schrägstellung der Bohlen kann noch durch andere Mittel erfolgen. So kann der Geräteteil mit den Bohlen an einem schwenkbaren Rahmen angeordnet sein, durch dessen Schrägstellung auch eine Schrägstellung der Bohlen im positiven oder negativen Sinn erfolgen kann,In certain circumstances it is advantageous to tilt the planks slightly. To carry out an inclination, lockable joints are arranged, which offer the possibility of adjusting each screed at an angle. An inclination the screed can be made by other means. Thus, the device part with the planks can be arranged on a pivotable frame, the inclination of which also allows the planks to be inclined in a positive or negative sense,

Der technische Fortschritt der Erfindung beruht zunächst auf der neuartigen Anordnung der Bohlen, nämlich der starr aufgehängten zwangsgeführten Abziehbohle und der schwimmend gelagerten Glättbohle, wodurch eine gute Nachverdichtung und saubere Glättung der Belagsoberfläche erfolgen kann. Diese guten Eigenschaften werden auch dadurch unterstützt, daß der Bohlenteil in Bezug auf das Kettenfahrzeug eine freie lotrechte Bewegung durchführen kann. Vorteilhaft ist ferner, daß gegenüber dem bekannten Gerät jede Bohle für sich im Anstellwinkel einstellbar und zusätzlich beide Bohlen gleichzeitig in ihrer Neigung verstellbar sind. Dadurch ist das Gerät für Belagstärken bis 15 cm und verschiedene Korndurchmesser der einzubauenden Materialien einsetzbar. Eine besonders gute und gleichmäßige Ausbildung der Schichten wird bei Schichtstärken unter 8 mm erzielt. Eine besonders gute Verteilung des Materials wird dadurch erreicht, daß die Abziehbohle an der Vorderkante eine hohe Querleiste aufweist, die das Überfallen von vor der Bohle liegendem Material über diese hinweg vermeiden soll und die außerdem gewährleistet, daß immer genügend Material vor der Abziehbohle vorhanden ist. Von großem Nutzen ist auch die besondere Aufhängung der Glättbohle mittels einer Gewindespindel mit Schraubenfeder, durch die der Anpreßdruck der Glättbohle einstellbar ist und außerdem die schwimmende Lagerung der Glättbohle beeinflußbar ist.The technical progress of the invention is based first of all on the novel arrangement of the screeds, namely the rigidly suspended positively driven screed and the floating screed, which allows good compaction and smooth smoothing of the surface of the covering. These good properties are also supported by the fact that the screed part can move freely perpendicularly with respect to the tracked vehicle. It is also advantageous that, compared to the known device, each screel can be adjusted in the angle of attack and additionally both screeds can be adjusted in inclination at the same time. This means that the device can be used for covering thicknesses of up to 15 cm and various grain diameters for the materials to be installed. A particularly good and uniform formation of the layers is achieved with layer thicknesses below 8 mm. A particularly good distribution of the material is achieved in that the screed has a high cross bar at the front edge, which should prevent material lying in front of the screed from falling over it and which also ensures that there is always enough material in front of the screed. The special suspension of the screed by means of a threaded spindle with a helical spring, by means of which the contact pressure of the screed can be adjusted and also the floating mounting of the screed can be influenced, is also of great benefit.

Für den Fall von Unebenheiten in der Unterlage kann eine Kufe vorgesehen werden, gegen die sich zwei Spindeln abstützen.In the event of unevenness in the base, a runner can be provided against which two spindles are supported.

Für die Schrägeinstellung der Bohlen bestehen verschiedene Möglichkeiten. So können beispielsweise die Tragorgane der Bohlen ein feststellbares Gelenk aufweisen, das zwecks Einstellung der Bohlen beweglich gemacht werden kann. Auch kann die Einstellung der Bohlen in einer Schräglage dadurch erfolgen, daß der Geräteteil an einem schwenkbaren Rahmen angeordnet ist, so daß durch Lageveränderung des Rahmens eine Schrägstellung der Bohlen im positiven oder negativen Sinn möglich ist.There are various options for the inclination of the planks. For example, the supporting members of the planks can have a lockable joint that is used for the purpose of being position of the planks can be made movable. The setting of the planks in an inclined position can also take place in that the device part is arranged on a pivotable frame, so that changing the position of the frame allows the planks to be inclined in a positive or negative sense.

The planks 1 and 2 are supported by a cross member 3, namely via the link 4, which are pivotally attached to the support 3 and Zap at their ends fen 5 and 6, through which the planks 1 and 2 are articulated by the handlebars 4. The arrows shown in Fig. 1 in the extension of the planks indicate the opposite movement of the movable planks. The screed device is arranged on a support frame 7, the legs of which are supported by chain drives 8. The suspension of the screed part on the frame 7 will be explained later with reference to FIG. 4. 9 the drive motor and 15 the associated switch box. To better emphasize the planks 1 and 2, these were shown with dashed lines. 14 is the side guide of the chain drive.

Fig. 2 zeigt die Ansicht des Gerätes von der Seite der Bohlen aus betrachtet. Das Gerät befindet sich auf der Schicht 12, die abgezogen und geglättet werden soll. Mit 4 sind die bereits in Fig. 1 erwähnten Lenker bezeichnet, an deren Unterseite die Bohlen 1 und 2 gelenkig angeordnet sind. Fig. 2 zeigt auch die Verstellvorrichtung 10, deren Einzelheiten in Fig. 4 dargestellt sind.Fig. 2 shows the view of the device viewed from the side of the planks. The device is located on layer 12, which is to be removed and smoothed. With 4 the handlebars already mentioned in Fig. 1 are designated, on the underside of which the planks 1 and 2 are articulated. FIG. 2 also shows the adjustment device 10, the details of which are shown in FIG. 4.

Fig. 3, 3' und 3" zeigen die Seitenansicht des Gerätes mit dem Rahmen 7 und dem Kettenantrieb 8. 9 ist der Antriebsmotor und 15 der Schaltkasten. Die Bohlen sind mit 1 und 2 bezeichnet und befinden sich in Normalstellung auf der Schicht 12, die abgezogen und geglättet werden soll. Mit 14 ist schematisch die Seitenführung angedeutet, die eine verstellbare Verbindung zwischen dem Rahmen 7 und dem Kettenfahrzeug aufweist. In Fig. 3' ist der Rahmenteil 7 gesenkt, wodurch eine Schrägstellung des Bohlengerätes bewirkt wird, wobei die Bohlen 1 und 2 an der Vorderkante etwas angehoben sind. In Fig. 3" ist die entgegengesetzte Steuerung dargestellt, bei der der Riemen 7 durch die Einrichtung 14 leicht mit dem Bohlengerät angehoben ist, wobei eine Schrägstellung der Bohlen 1 und 2 mit Anheben der hinteren Kante bewirkt wird. Durch die beschriebene Vorrichtung kann eine exakte und vorher bestimmte Schrägstellung der Bohlen erreicht werden.3, 3 'and 3 "show the side view of the device with the frame 7 and the chain drive 8. 9 is the drive motor and 15 the switch box. The planks are labeled 1 and 2 and are in the normal position on the layer 12, The side guide, which has an adjustable connection between the frame 7 and the tracked vehicle, is indicated schematically by 14. In Fig. 3 ', the frame part 7 is lowered, thereby causing the screed device to be inclined, whereby the screeds 1 and 2 are slightly raised at the front edge. FIG. 3 "shows the opposite control, in which the belt 7 is raised slightly by the device 14 with the screed device, with the screeds 1 and 2 being inclined with the rear edge being raised is effected. With the device described, an exact and previously determined inclination of the planks can be achieved.

Fig. 4 zeigt die Einrichtung, mit der der Bohlenteil am Rahmen 7 angeordnet ist. Wie die Darstellung erkennen läßt, besteht diese Vorrichtung 10 aus einer Gewindespindel 19, die oben einen drehbaren Lenker 16 aufweist. Zwischen diesem Lenker 16 und der Führung 17 ist eine Spiralfeder 18 vorgesehen, die eine ungewollte Verstellung verhindert und die Gewindespindel in ihrer jeweiligen Stellung arretiert. Die Gewindespindel 19 ist in dem Ansatz 20 geführt, so daß durch Drehen des Lenkers 16 der Träger 3 für die Bohlen angehoben und gesenkt werden kann. Wie die Darstellung ferner erkennen läßt, ist der untere Teil der Gewindespindel nämlich 21, gewindefrei. Für die Inbetriebnahme wird durch Drehen des Lenkers 16 der Träger 3 so weit gesenkt, daß eine Führung in lotrechter Richtung frei beweglich arbeiten kann, ohne daß eine Behinderung durch das Kettenfahrzeug gegenüber lotrechten Bewegungen erfolgt. 17 ist die Verbindung mit Rahmen 7.Fig. 4 shows the device with which the screed part is arranged on the frame 7. As can be seen from the illustration, this device 10 consists of a threaded spindle 19 which has a rotatable link 16 at the top. Between this handlebar 1 6 and the guide 17, a spiral spring 18 is provided, which prevents unwanted adjustment and locks the threaded spindle in its respective position. The threaded spindle 19 is guided in the neck 20 so that the beam 3 for the planks can be raised and lowered by turning the handlebar 16. As can also be seen from the illustration, the lower part of the threaded spindle is 21, thread-free. For commissioning, the support 3 is lowered by turning the handlebar 16 so that a guide can work freely in the vertical direction without being impeded by the tracked vehicle with respect to vertical movements. 17 is the connection to frame 7.

Fig. 5 zeigt in schematischer Darstellung die Anordnung der Bohlen 1, 2 an dem Lenker 4. Der Tragschaft 41 der Glättbohle 2 ist nach oben verlängert und trägt eine Spiralfeder oder Schraubenfeder 42. Am oberen Ende der Spindel befindet sich eine Flügelmutter 45, die einen einstellbaren Druck auf die Scheibe 43 und damit auf die Schraubenfeder 42 ausübt. Durch die Erhöhung des Federdruckes kann der Anpreßdruck der Glättbohle 2 auf das Bodenmaterial eingestellt werden, wobei als Gegenlager der Träger 3 dient, der eine unten angeschweißte Scheibe 44 aufweist. Weist die Schraubenfeder 42 nur eine geringe Spannung auf, wirkt die Glättbohle 2 mit ihrem vollen Gewicht auf das eingebaute Material. Wird die Spannung der Schraubenfeder 42 erhöht, nimmt der Anpreßdruck ab. Es wurde festgestellt, daß durch die Erhöhung des Anpreßdruckes die flüssigen Bestandteile der Mischung veranlaßt werden nach oben zu steigen, wodurch die Festigkeit an der Oberfläche erhöht und ein Austrocknen verhindert wird. Infolge der Anordnung der Schraubenfeder 42 wird auch eine schwimmende Befestigung der Bohle 2 erreicht. Auf der linken Seite ist die Abziehbohle 1 am Lenker 4 mittels eines Zapfens 46 befestigt, der am oberen Ende eine Mutter 48 mit Splint trägt. Es ist auch möglich, in das Halteorgan der Bohlen unterhalb des Lenkers 4 ein feststellbares Gelenk einzubauen, das die Möglichkeit bietet, für jede Bohle individuell eine Schrägstellung einzustellen.Fig. 5 shows a schematic representation of the arrangement of the planks 1, 2 on the handlebar 4. The support shaft 41 of the screed 2 is extended upwards and carries a coil spring or coil spring 42. At the upper end of the spindle there is a wing nut 45, one adjustable pressure on the disc 43 and thus exerts on the coil spring 42. By increasing the spring pressure, the contact pressure of the screed 2 on the floor material can be adjusted, the support 3, which has a disk 44 welded on at the bottom, serving as the counter bearing. If the coil spring 42 has only a slight tension, the screed 2 acts with its full weight on the installed material. If the tension of the coil spring 42 is increased, the contact pressure decreases. It has been found that increasing the contact pressure causes the liquid constituents of the mixture to rise, which increases the strength on the surface and prevents drying out. As a result of the arrangement of the coil spring 42, a floating fastening of the screed 2 is also achieved. The screed 1 is on the left attached to the handlebar 4 by means of a pin 46 which carries a nut 48 with a cotter pin at the upper end. It is also possible to install a lockable joint in the holding member of the planks below the handlebar 4, which offers the possibility of individually setting an inclined position for each plank.

Fig. 6 zeigt in schematischer Darstellung die Anordnung von zwei Spindeln 27, die von dem Rahmen 28 getragen werden und innerhalb des Rahmens durch eine Gewindeanordnung 25 verstellbar ist. Eine Gewindeführung verhindert eine Beschädigung des Gewindes. Das untere Ende 32 ist bei dieser Anordnung ungeschützt. Die Spindeln 32 enden in Halterungen 33, die auf der Kufe 34 angeordnet sind. Diese Vorrichtung kann verwendet werden, wenn die Unterlagen etwas uneben sind, wobei die Kufe 34 diese Unebenheiten ausgleichen kann. An der Vorderkante der Bohle 1 ist noch ein Schild 31 angeordnet, der das Überfallen des Materials verhindert und dafür sorgt, daß eine genügend große Menge Material vor der Bohle 1 zwecks guter Verteilung vorhanden ist.Fig. 6 shows a schematic representation of the arrangement of two spindles 27 which are carried by the frame 28 and can be adjusted within the frame by a threaded arrangement 25. A thread guide prevents damage to the thread. The lower end 32 is unprotected in this arrangement. The spindles 32 end in brackets 33 which are arranged on the runner 34. This device can be used when the backing is somewhat uneven and the runner 34 can compensate for these unevenness. At the front edge of the screed 1 there is also a sign 31 which prevents the material from falling over and ensures that a sufficiently large amount of material is present in front of the screed 1 for good distribution.
