Description

Die Erfindung betrifft eine Ankervorrichtung zur Verankerung in mindestens einem Bauteil, insbesondere in mindestens einer Betonwand.The invention relates to an anchoring device for anchoring in at least one component, in particular in at least one concrete wall.

Beispielsweise zum Transport von Doppelwänden in einem Fertigteilwerk und zur Montage auf der Baustelle werden vorzugsweise bügelartige Ankervorrichtungen aus Bewehrungsstahl verwendet. Die Bügel binden dabei in beide Wandschalen ein. Ein Problem bei diesen Ankervorrichtungen ist, dass beim Anheben der Wände, bedingt durch die Geometrie der Bügel, ein hoher Druck auf die Druckbolzen zwischen den Schenkeln auftritt. Dieser Druck entsteht, weil die Bügel aus einem gebogenen Stahlbügel bestehen, der sich bei Lastzunahme zu einer Geraden strecken würde. Das soll der Druckbolzen zwischen den Bügeln verhindern.For example, for the transport of double walls in a precast plant and for installation on the site preferably bow-shaped anchor devices are used from reinforcing steel. The stirrups bind in both wall shells. A problem with these anchor devices is that when lifting the walls, due to the geometry of the brackets, a high pressure on the pressure pins between the legs occurs. This pressure is created because the brackets consist of a bent steel strap that would stretch to a straight line when the load increases. This is to prevent the pressure pin between the straps.

Wird der Druck jedoch zu hoch, beginnt der Druckbolzen zu knicken und damit wird der Stahl durch die Momente im Bereich des Einbindens in die Betonhälften herausgezogen und es kommt zu Abplatzungen des Betons und schließlich zum Versagen. Dies geschieht auch, wenn der Bügel in Zugrichtung, üblicherweise 30°- 45°, eingebaut wird.However, if the pressure is too high, the pressure pin begins to buckle and thus the steel is pulled out by the moments in the area of the binding in the concrete halves and it comes to chipping of the concrete and finally to failure. This also happens when the bracket in the pulling direction, usually 30 ° - 45 °, installed.

Bein sogenannten Querzug, also wenn ein liegendes Bauteil aufgerichtet wird, werden die Bügel ungleichmäßig belastet und verstärken dieses Problem zusätzlich.Leg so-called Querzug, so when a lying component is erected, the straps are unevenly loaded and amplify this problem in addition.

Es sind auch Ankervorrichtungen bekannt, die in jeder Schale mit zwei Bügeln so eingebunden sind, dass die Lasten schräg in die jeweilige Wandhälfte eingeleitet werden und somit höhere Auszugswerte erreichen. Diese Ankervorrichtungen sind jedoch nicht sehr verbreitet, da sie geometriebedingt nur für eine Wandstärke eingesetzt werden können, was die Lagerhaltung in Betonwerken erschwert.There are also anchor devices known which are involved in each shell with two brackets so that the loads are introduced obliquely into the respective wall half and thus achieve higher pullout values. However, these anchor devices are not very common, as they can be used geometriebingt only for a wall thickness, which complicates the storage in concrete plants.

Der Erfindung liegt die Aufgabe zugrunde, eine Ankervorrichtung zu schaffen, die hohe Tragkräfte zulässt und sowohl für Axial- als auch für Schrägzug bestens geeignet ist und neben der Eigenschaft als Transportanker auch als Verbundanker zwischen zwei Bauteilen genutzt werden kann.The invention has for its object to provide an anchor device that allows high load capacity and is well suited for both axial and diagonal pull and can be used in addition to the property as a transport anchor as a composite anchor between two components.

Die der Erfindung zugrundeliegende Aufgabe wird gelöst durch die Ankervorrichtung zur Verankerung in mindestens einem Bauteil, insbesondere in mindestens einer Betonwand, nach Anspruch 1, wobei die Ankervorrichtung ein Ankerelement mit plattenförmiger Grundstruktur aufweist. Durch die flächige Ausgestaltung weist die erfindungsgemäße Ankervorrichtung eine wesentlich größere Biegesteifigkeit auf als der herkömmliche Transportbügel. Zudem ist eine größere Oberfläche dieses Ankers mit dem zu tragenden Bauteil in Kontakt bringbar, so dass größere Tragkräfte zwischen der Ankervorrichtung und dem zu tragenden Bauteil übertragbar sind.The object underlying the invention is achieved by the anchoring device for anchoring in at least one component, in particular in at least one concrete wall, according to claim 1, wherein the anchoring device comprises an anchor element with a plate-shaped basic structure. Due to the planar configuration, the anchoring device according to the invention has a much greater flexural rigidity than the conventional transporting bow. In addition, a larger surface area of this armature can be brought into contact with the component to be supported so that larger load-bearing forces can be transmitted between the anchor device and the component to be supported.

Bevorzugte Ausführungen und Weiterbildung der Erfindung werden in den Unteransprüchen beansprucht.Preferred embodiments and development of the invention are claimed in the subclaims.

Es kann sich als hilfreich erweisen, wenn die Geometrie des Ankerelementes entsprechend einem Kraftverlauf durch das Ankerelement in mindestens einem Belastungszustand modifiziert ist. Der Belastungszustand bezieht sich vorzugsweise auf einen Einbauzustand der Ankervorrichtung, wie er beispielsweise in Fig. 1 oder Fig. 2 dargestellt ist. In diesem Einbauzustand wird die Ankervorrichtung beispielsweise über einen Lasthaken mit einer Hebevorrichtung in Eingriff gebracht, so dass die Ankervorrichtung das Gewicht der daran verankerten Last, d.h. des daran verankerten Bauteils oder der daran verankerten Bauteile trägt. Die Ankervorrichtung stellt das Bindeglied zwischen der Hebevorrichtung und der Last dar. Man kennt Bauteile, die für mindestens einen Belastungszustand hinsichtlich der Geometrie modifiziert sind, beispielsweise aus dem Bereich der Leichtbautechnik, wo die Bauteile derart ausgelegt werden, um bei minimalem Gewicht und Materialeinsatz ein Maximum an Festigkeit und Steifigkeit zu erhalten. Die Geometrie des Ankerelementes ist dementsprechend mindestens für den Belastungszustand optimiert, der vorliegt, wenn der aus der Ankervorrichtung und der angehängten Last bestehende Transportverbund an der Hebevorrichtung hängt. Die Geometrie des Ankerelements ist aber vorzugsweise für mehr als einen Belastungszustand ausgelegt bzw. optimiert, so dass das Ankerelement in unterschiedlichen Anwendungen (Fig. 1 oder Fig. 2) zum Einsatz kommen kann.It may prove helpful if the geometry of the anchor element is modified according to a force curve through the anchor element in at least one load state. The load condition preferably refers to an installation state of the anchor device, as it is, for example, in Fig. 1 or Fig. 2 is shown. In this installed state, the anchoring device is brought into engagement with a lifting device, for example via a load hook, so that the anchoring device carries the weight of the load anchored thereto, ie the component anchored thereto or the components anchored thereto. The anchor device provides the link between the jack and the load. Components known to be modified in geometry for at least one load state, such as lightweight design where the components are designed to maximize weight and material usage, are known to obtain strength and rigidity. Accordingly, the geometry of the anchor element is optimized for at least the load condition that exists when the transport composite consisting of the anchor device and the attached load hangs on the lifting device. However, the geometry of the anchor element is preferably designed or optimized for more than one load state, so that the anchor element in different applications ( Fig. 1 or Fig. 2 ) can be used.

Es kann von Vorteil sein, wenn das Ankerelement mindestens einen Abschnitt mit verringerter Dicke aufweist. Der Abschnitt mit verringerter Dicke ist vorzugsweise in einem schwach beanspruchten Abschnitt des Ankerelements ausgebildet und trägt dazu bei, dass Gewicht des Ankerelements zu verringern. Durch den Abschnitt mit verringerter Dicke verringert sich auch die Wärmeleitung durch das Ankerelement.It may be advantageous if the anchor element has at least one section of reduced thickness. The reduced thickness portion is preferably formed in a weakly stressed portion of the anchor member and helps to reduce the weight of the anchor member. The reduced thickness section also reduces heat conduction through the anchor element.

Es kann sich auch als nützlich erweisen, wenn das Ankerelement mindestens eine Ausnehmung aufweist. Die Ausnehmung ist vorzugsweise in einem sehr schwach beanspruchten Abschnitt des Ankerelements ausgebildet und trägt dazu bei, dass Gewicht des Ankerelements zu verringern. Durch die Ausnehmung verringert sich auch die Wärmeleitung durch das Ankerelement.It may also be useful if the anchoring element has at least one recess. The recess is preferably formed in a very weakly stressed portion of the anchor member and contributes to that weight reduce the anchor element. The recess also reduces the heat conduction through the anchor element.

Es kann auch von Nutzen sein, wenn die Ankervorrichtung zumindest ein Vorsprungselement aufweist, das gegenüber der plattenförmigen Grundstruktur des Ankerelements hervorsteht und sich vorzugsweise quer, bevorzugt senkrecht zum Ankerelement erstreckt. Dadurch gewinnt die Ankervorrichtung eine räumliche Struktur mit größerer Oberfläche, so dass die Ankervorrichtung besser in dem Bauteil verankerbar und einbindbar ist. Außerdem kann das Vorsprungselement gezielt dazu eingesetzt werden, die Festigkeit und Steifigkeit des Ankerelements in kritischen Bereichen zu erhöhen.It may also be useful if the anchoring device has at least one projection element which protrudes relative to the plate-shaped basic structure of the anchor element and preferably extends transversely, preferably perpendicularly, to the anchor element. As a result, the anchoring device acquires a spatial structure with a larger surface, so that the anchoring device can be anchored and integrated better in the component. In addition, the projection element can be used specifically to increase the strength and rigidity of the anchor element in critical areas.

Es kann sich als vorteilhaft erweisen, wenn zumindest ein Vorsprungselement als Rippe, Wulst, Ausbauchung, Wölbung, Abkantung, Aufdickung, Prägung oder als Bewehrungselement, vorzugsweise Bewehrungsstahl ausgebildet ist. Dadurch kann die Ankervorrichtung besser in dem Bauteil verankert werden und größere Lasten tragen. Die Rippe ist ein ideales Versteifungselement und kann zur Verbesserung der Festigkeit und Steifigkeit des Ankerelements gezielt auf dem Ankerelement positioniert werden. Vorzugsweise sind mehrere als Versteifungselemente vorgesehene Rippen derart angeordnet, dass sie im Wesentlichen die gesamte plattenförmige Grundstruktur des Ankerelements fachwerkartig überziehen, um die Geometrie des Ankerelementes entsprechend mindestens einem Belastungszustand zu optimieren. Ein als Wulst ausgebildetes Vorsprungselement ist vorzugsweise in einem Randbereich des Ankerelements, z.B. in einem Randbereich angrenzend an Ausnehmungen bzw. Öffnungen und/oder in einem Randbereich angrenzend an Abschnitte mit verringerter Dicke vorgesehen, um das Ankerelement diesen Bereichen gezielt zu verstärken.

As a result, the anchor device can be better anchored in the component and carry larger loads. The rib is an ideal stiffening element and can be selectively positioned on the anchor element to improve the strength and rigidity of the anchor element. Preferably, a plurality of ribs provided as stiffening elements are arranged such that they substantially cover the entire plate-shaped basic structure of the anchoring element in a truss-like manner in order to optimize the geometry of the anchoring element in accordance with at least one loading state. A projection element designed as a bead is preferably provided in an edge region of the anchor element, for example in an edge region adjacent to recesses or openings and / or in an edge region adjacent to sections of reduced thickness in order to purposefully reinforce the anchor element in these regions. A protrusion element formed as a bulge, a curvature, a fold is preferably formed integrally with the anchor element and gives the anchor element a spatial dimension substantially without changing the thickness of the anchor element. The fold is preferably provided in the outer edge region of the anchor element, but may also be provided in an inner edge region of the anchor element, for example in an edge region adjacent to openings or recesses.

The reinforcing element is preferably an element of greater strength and rigidity than the anchor element itself and is preferably arranged only locally in particularly heavily stressed sections of the anchor element.

Es kann sich als hilfreich erweisen, wenn das Vorsprungselement integral mit der Ankerplatte ausgebildet ist. Dadurch weist das Ankerelement eine besonders große Festigkeit und Steifigkeit auf und die Fertigung des Ankerelements erweist sich einfach.It may prove helpful if the projection element is formed integrally with the anchor plate. As a result, the anchor element has a particularly high strength and rigidity and the manufacture of the anchor element proves to be simple.

Es kann sich als nützlich erweisen, wenn das Vorsprungselement mit dem Ankerelement lösbar verbindbar ist, vorzugsweise gegenüber dem Ankerelement verrastbar und/oder auf das Ankerelement aufsteckbar ist. Dadurch kann das Vorsprungselement zweckoptimiert gefertigt werden. Die Ankervorrichtung kann bedarfsgerecht mit einem oder mehreren Vorsprungselementen aufgerüstet werden, die vorzugsweise in unterschiedlichen Positionen angeordnet werden, um unterschiedliche Funktionen zu erfüllen. Nach dem Baukastenprinzip können für ein Ankerelement unterschiedliche Vorsprungselemente vorgesehen sein, die bei Bedarf mit dem Ankerelement verbunden werden, um die Geometrie des Ankerelementes entsprechend einem Kraftverlauf durch das Ankerelement in mindestens einem Belastungszustand zu modifizieren und zu optimieren.It may prove useful if the projection element is detachably connectable to the anchor element, preferably latched relative to the anchor element and / or attachable to the anchor element. As a result, the projection element can be manufactured optimized for the purpose. The anchor device may be upgraded as needed with one or more projection elements, which are preferably arranged in different positions to perform different functions. According to the modular principle, different projection elements can be provided for an anchor element, which are connected as needed to the anchor element in order to modify and optimize the geometry of the anchor element according to a force curve through the anchor element in at least one load state.

Es kann sich als praktisch erweisen, wenn eine Ausnehmung eine Eingriffsöffnung für eine Hebevorrichtung, vorzugsweise für einen Kranhaken bildet. Dadurch, dass die Aufnahmeöffnung für die Hebevorrichtung in das Ankerelement integriert ist, können große Kräfte über die Ankervorrichtung übertragen werden.It may prove practical if a recess forms an engagement opening for a lifting device, preferably for a crane hook. Characterized in that the receiving opening for the lifting device is integrated into the anchor element, large forces can be transmitted via the anchor device.

Es kann sich auch als vorteilhaft erweisen, wenn eine Ausnehmung eine Aufnahmeöffnung für zumindest ein Vorsprungselement bildet. Dadurch kann die Ankervorrichtung bedarfsgerecht aufgerüstet werden. Wenn kein Vorsprungselement benötigt wird, ist das Gewicht des Ankerelements aufgrund der Öffnung verringert.It may also prove advantageous if a recess forms a receiving opening for at least one projection element. As a result, the anchor device can be upgraded as needed. If no protrusion member is needed, the weight of the anchor member is reduced due to the opening.

Es kann sich auch von Vorteil sein, wenn zumindest ein Vorsprungselement eine Ausnehmung oder einen Abschnitt mit verringerter Dicke zumindest abschnittsweise umrandet. Dadurch wird das Ankerelement in kritischen Bereichen gezielt verstärkt.It can also be advantageous if at least one projection element surrounds a recess or a section of reduced thickness at least in sections. As a result, the anchor element is specifically reinforced in critical areas.

Es kann sich auch als hilfreich erweisen, wenn das Ankerelement aus Stahl hergestellt, vorzugsweise geschmiedet, gestanzt, gegossen oder gekantet ist, oder aus einem faserhaltigen Werkstoff, vorzugsweise einem glasfaser- und/oder kohlefaserhaltigen Werkstoff gefertigt ist. Diese Werkstoffe zeichnen sich durch große Festigkeit und Steifigkeit aus und eignen sich besonders zum Tragen großer Lasten.It may also be helpful if the anchor element is made of steel, preferably forged, stamped, cast or folded, or made of a fibrous material, preferably a glass fiber and / or carbon fiber-containing material. These materials are characterized by high strength and rigidity and are particularly suitable for carrying large loads.

Es kann sich auch als nützlich erweisen, wenn das Ankerelement einen im Wesentlichen polygonalen, vorzugsweise rechteckigen, Umriss aufweist. Dadurch ist das Ankerelement mit geringem Aufwand und Materialverbrauch herstellbar.It may also be useful if the anchor element has a substantially polygonal, preferably rectangular, outline. As a result, the anchor element can be produced with little effort and material consumption.

Es kann sich auch als praktisch erweisen, wenn das Ankerelement symmetrisch, vorzugsweise spiegelsymmetrisch und/oder rotationssymmetrisch, bevorzugt mehrfach symmetrisch, aufgebaut ist. Dadurch ist das Ankerelement in unterschiedlichen Anordnungen in einem Bauteil einbindbar und verankerbar. Die spiegelsymmetrische Ausbildung des Ankerelements begünstigt insbesondere die Verwendung als Ankerplatte für Doppelwände.It can also prove to be practical if the anchor element is constructed symmetrically, preferably mirror-symmetrically and / or rotationally symmetrically, preferably multiply symmetrically. As a result, the anchor element in different arrangements in a component can be embedded and anchored. The mirror-symmetrical design of the anchor element favors in particular the use as an anchor plate for double walls.

Es kann sich auch als vorteilhaft erweisen, wenn das Ankerelement und/oder die Ankervorrichtung stapelfähig ist. Dadurch können die Ankerelemente und/oder die Ankervorrichtungen mit geringem Raumbedarf gelagert werden. Vorzugsweise ist das Ankerelement und/oder die Ankervorrichtung derart stapelfähig, dass sich die Stapelhöhe pro zusätzlichem Ankerelement bzw. pro zusätzlicher Ankervorrichtung jeweils nur um die Dicke eines Ankerelements erhöht, wobei vorderseitige Erhebungen eines Ankerelements bzw. einer Ankervorrichtung in rückseitige Vertiefungen eines benachbarten Ankerelements bzw. einer benachbarten Ankervorrichtung passend eingreifen. Etwaig überstehende Vorsprungselemente einer Ankervorrichtung werden vorzugsweise vor dem Stapeln abmontiert und werden gesondert gelagert. Bei Gebrauch wird die Ankervorrichtung wieder bedarfsgerecht aufgerüstet.It may also prove advantageous if the anchor element and / or the anchor device is stackable. As a result, the anchor elements and / or the anchor devices can be stored with a small space requirement. Preferably, the anchor element and / or the anchor device is stackable such that the stack height per additional anchor element or per additional anchor device increases only by the thickness of an anchor element, wherein front elevations of an anchor element or an anchor device in back recesses of an adjacent anchor element or engage an adjacent anchor device fit. Any projecting protrusion elements of an anchor device are preferably removed before stacking and are stored separately. In use, the anchor device is upgraded again as needed.

Es kann sich auch als nützlich erweisen, wenn das Ankerelement zumindest abschnittsweise in ein Bauteil, vorzugsweise ein Betonteil eingebunden ist. Ein fließfähiges, abbindendes Medium wie Beton kann die Ankervorrichtung im fließfähigen Zustand umfließen und im gebundenen Zustand formschlüssig umgreifen, so dass die Ankervorrichtung nur durch Zerstörung aus dem Betonteil herausziehbar ist. Dadurch kann die Ankervorrichtung große Lasten tragen.It may also be useful if the anchor element is at least partially integrated into a component, preferably a concrete part. A flowable, setting medium such as concrete can flow around the anchor device in the flowable state and positively embrace in the bound state, so that the anchor device can be pulled out of the concrete part only by destruction. This allows the anchor device to carry large loads.

Es kann sich auch als hilfreich erweisen, wenn sich das Ankerelement quer, vorzugsweise senkrecht zu einer Oberfläche des Bauteils erstreckt. Wenn das Ankerelement quer, vorzugsweise senkrecht von einer Oberfläche des Bauteils hervorsteht, ist das Ankerelement für eine Hebeeinrichtung leicht zugänglich und die Kraftübertragung zwischen Hebeeinrichtung und Bauteil ist ideal.It may also prove helpful if the anchor element extends transversely, preferably perpendicular to a surface of the component. When the anchor element transversely, preferably perpendicularly protrudes from a surface of the component, the anchor element for a lifting device is easily accessible and the power transmission between the lifting device and the component is ideal.

Es kann sich auch als günstig erweisen, wenn das Ankerelement zumindest abschnittsweise in unterschiedliche Bauteile eingebunden ist. Dadurch können mehrere Bauteile gleichzeitig getragen werden. Zusätzlich können die unterschiedlichen Bauteile durch die Ankervorrichtung mit hoher Maßhaltigkeit zueinander positioniert werden.It can also prove to be advantageous if the anchor element is at least partially integrated into different components. As a result, several components can be worn simultaneously. In addition, the different components can be positioned by the anchor device with high dimensional accuracy to each other.

Das Ankerelement ist dabei vorzugsweise als Ankerplatte für Doppelwände ausgebildet.A preferred embodiment of the invention relates to a transport composite, comprising an anchor device according to one of the preceding claims and at least two components, wherein the anchor element is at least partially integrated into the components. The anchor element is preferably designed as an anchor plate for double walls.

Es kann sich als hilfreich erweisen, wenn sich das Ankerelement zumindest abschnittsweise zwischen den Bauteilen erstreckt. Dadurch werden die unterschiedlichen Bauteile durch die Ankervorrichtung auf Distanz gehalten mit hoher Maßhaltigkeit zueinander positioniert.It may prove helpful if the anchor element extends at least in sections between the components. Thereby, the different components are held by the anchor device at a distance with high dimensional accuracy to each other positioned.

Es kann sich auch als nützlich erweisen, wenn die Ankervorrichtung und zwei sich gegenüber liegende Flächen der Bauteile im Wesentlichen senkrecht zueinander ausgerichtet sind. Durch werden Kräfte optimal zwischen der Ankervorrichtung und den Bauteilen übertragen.It may also prove useful when the anchor device and two opposing surfaces of the components are substantially perpendicular to each other. By forces are optimally transferred between the anchor device and the components.

Es kann sich auch als vorteilhaft erweisen, wenn der Transportverbund als Doppelwand ausgebildet ist.

Detaillierte Beschreibung der bevorzugten Ausführungsbeispiele:DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Die Erfindung betrifft eine Ankervorrichtung zur Verankerung in mindestens einem Bauteil 8, insbesondere in mindestens einer Betonwand 8, wobei die Ankervorrichtung ein Ankerelement 1 mit plattenförmiger Grundstruktur aufweist. Das Ankerelement 1 wird demnach auch als Ankerplatte 1 bezeichnet.The invention relates to an anchor device for anchoring in at least one component 8, in particular in at least one concrete wall 8, wherein the anchor device has an anchor element 1 with a plate-shaped basic structure. The anchor element 1 is therefore also referred to as anchor plate 1.

Das Ankerelement 1 weist vorzugsweise einen polygonalen, insbesondere dreieckigen, viereckigen, fünfeckigen, sechseckigen, siebeneckigen, achteckigen, neuneckigen, zehneckigen, elfeckigen oder zwölfeckigen Umriss auf.The anchor element 1 preferably has a polygonal, in particular triangular, quadrangular, pentagonal, hexagonal, heptagonal, octagonal, triangular, ten-cornered, ivy or dodecagonal outline.

Die Geometrie des Ankerelements 1 ist entsprechend einem Kraftverlauf durch das Ankerelement 1 in mindestens einem Belastungszustand der Ankervorrichtung modifiziert. Ein erster Belastungszustand liegt vor, wenn die Ankervorrichtung entsprechend Fig. 1 jeweils abschnittsweise in zwei Betonwände 8 eingebunden ist, so dass sich die Betonwände 8 parallel zueinander und senkrecht zur Ankerplatte 1 erstrecken und mit der Ankervorrichtung einen Transportverbund bilden, wobei ein Kranhaken einer Hebeeinrichtung (nicht dargestellt) in die in Fig. 1 oben liegende Ausnehmung 2 in der Ankerplatte 1 eingehängt ist und das Gewicht des Transportverbunds trägt. Die Hebekraft der Hebeeinrichtung wird durch den Pfeil dargestellt. Die Ankervorrichtung bzw. Ankerplatte 1 weist in diesem Ausführungsbeispiel einen im Wesentlichen rechteckigen Umriss auf und ist derart in die Betonwände 8 eingebunden, dass eine Längsmittelachse der Ankerplatte 1 parallel zu den Oberflächen der Betonwände 8 ausgerichtet ist. Die Geometrie des Ankerelements 1 ist entsprechend dem Kraftverlauf durch das Ankerelement 1 im ersten Belastungszustand gemäß Fig. 1 modifiziert. Dabei ist der Materialeinsatz für die Ankerplatte für die jeweilige Last (= Gewichtskraft der Betonwände 8 plus Aufschlag bzw.The geometry of the anchor element 1 is modified in accordance with a force curve through the anchor element 1 in at least one loading state of the anchor device. A first load condition exists when the anchor device correspondingly Fig. 1 each partially in two concrete walls 8 is integrated, so that the concrete walls 8 extend parallel to each other and perpendicular to the anchor plate 1 and form a transport network with the anchor device, a crane hook a lifting device (not shown) in the in Fig. 1 overhead recess 2 is mounted in the anchor plate 1 and carries the weight of the transport composite. The lifting force of the lifting device is represented by the arrow. The anchor device or anchor plate 1 has in this embodiment, a substantially rectangular outline and is integrated into the concrete walls 8 such that a longitudinal center axis of the anchor plate 1 is aligned parallel to the surfaces of the concrete walls 8. The geometry of the anchor element 1 is according to the force curve by the anchor element 1 in the first load state according to Fig. 1 modified. Here, the material used for the anchor plate for each load (= weight of the concrete walls 8 plus surcharge or

Sicherheitsmarge) minimiert bzw. optimiert. Man kennt derartige Modifikationen von Elementen mit plattenförmiger Grundstruktur z.B. aus der Leichtbautechnik. In schwach beanspruchten Bereichen wird die Plattenstärke bzw. die Plattendicke entsprechend verringert und in stärker beanspruchten Bereichen entsprechend erhöht. Dem Kraftverlauf folgend sind Ausnehmungen 2, 3, 6, Abschnitte mit verringerter Dicke 4 und Vorsprungselemente 5, 7, an der Ankerplatte 1 vorgesehen.Safety margin) minimized or optimized. One knows such modifications of elements with plate-shaped basic structure, e.g. from the lightweight construction technique. In areas subject to low stress, the panel thickness or panel thickness is correspondingly reduced and correspondingly increased in more heavily used areas. Following the force curve are recesses 2, 3, 6, portions of reduced thickness 4 and protrusion elements 5, 7, provided on the anchor plate 1.

Die in Fig. 1 dargestellte Ankervorrichtung umfasst vier kreuzförmig angeordnete und von wulstförmigen Vorsprungselementen 5 zumindest abschnittsweise umrandete Eingriffsöffnungen 2 für Kranhaken und dergleichen. Die Eingriffsöffnungen 2 weisen zur jeweiligen Außenkante der Ankerplatte 1 hin einen bogenförmigen Rand auf und werden zum Mittelpunkt der Ankerplatte 1 hin schmaler. Der Kraftangriffspunkt z.B. für den Kranhaken ist jeweils mittig an einem die Eingriffsöffnung 2 umrandenden, bogenförmigen Randbereich der Ankerplatte 1 vorgesehen, wenn der Transportverbund entsprechend der Darstellung in Fig. 1 angehoben wird. Bei Querzug verschiebt sich der Kraftangriffspunkt entlang des die Eingriffsöffnung 2 umrandenden, bogenförmigen Randbereichs der Ankerplatte 1 entsprechend. Die Ankerplatte 1 ist daher im bogenförmigen Randbereich durch die wulstförmigen Vorsprungselemente 5 entsprechend verstärkt. Zwischen den Eingriffsöffnungen 2 sind im Wesentlichen kreisförmige Ausnehmungen 3 vorgesehen, die an einem zum Mittelpunkt der Ankerplatte 1 weisenden Bogenbereich in Abschnitte mit verringerter Dicke 4 übergehen. Die Ausnehmungen 3 sowie die Abschnitte mit verringerter Dicke 4 dienen der Gewichtseinsparung und verringern die Wärmeleitung durch die Ankerplatte 1. Daneben umfasst die Ankerplatte 1 weitere Ausnehmungen bzw. Öffnungen und Vorsprungselemente 5, um eine formschlüssige Verbindung zu den Bauteilen bzw. Betonwänden 8 zu bewerkstelligen. Die Ankerplatte 1 weist einen im Wesentlichen doppelt spiegelsymmetrischen Aufbau auf, wobei die Längsmittelachse sowie die Quermittelachse der Ankerplatte 1 die Spiegelachsen bilden.In the Fig. 1 Anchor device shown comprises four cross-shaped and bead-shaped protrusion elements 5 at least partially bordered engagement openings 2 for crane hooks and the like. The engagement openings 2 have for the respective outer edge of the anchor plate 1 towards an arcuate edge and become narrower to the center of the anchor plate 1 out. The force application point, for example, for the crane hook is in each case provided centrally on an arcuate edge region of the anchor plate 1 which surrounds the engagement opening 2, when the transport composite, as shown in FIG Fig. 1 is raised. In the case of transverse tension, the force application point shifts along the arcuate edge region of the anchor plate 1 that surrounds the engagement opening 2. The anchor plate 1 is therefore correspondingly reinforced in the arcuate edge region by the bead-shaped projection elements 5. Between the engagement openings 2, substantially circular recesses 3 are provided, which merge into sections of reduced thickness 4 at an arch area facing the center of the anchor plate 1. The recesses 3 and the sections of reduced thickness 4 serve to save weight and reduce the heat conduction through the anchor plate 1. In addition, the anchor plate 1 comprises further recesses or openings and projection elements 5 in order to accomplish a positive connection to the components or concrete walls 8. The anchor plate 1 has a substantially double mirror-symmetrical structure, wherein the longitudinal center axis and the transverse center axis of the anchor plate 1 form the mirror axes.

Die wulstförmigen Vorsprungselemente 5 stehen quer bzw. im Wesentlichen senkrecht zur Ankerplatte 1 hervor. Weitere Vorsprungselemente 5 in der Gestalt von zylindrischen und/oder kegel- bzw. kegelstumpfförmigen Elementen, die über die Ankerplatte 1 senkrecht hervorstehen, sind z.B. paarweise im äußeren Randbereich der Ankerplatte 1 entlang der Außenkanten der Ankerplatte 1 angeordnet. Vorzugsweise in den Eckbereichen der Ankerplatte 1 sind Auskragungen in Form von ¾-Bögen dargestellt, die jeweils mittig eine Aufnahme 6 für Bewehrungsstähle 7 bilden. Die Bewehrungsstähle 7 sind quer bzw. senkrecht zur Ankerplatte 1 anordenbar, um der Ankervorrichtung eine räumliche Dimension zu verleihen, und werden ebenfalls als Vorsprungselemente 5 bezeichnet.The bead-shaped projection elements 5 protrude transversely or substantially perpendicular to the anchor plate 1. Further projection elements 5 in the form of cylindrical and / or conical or frustoconical elements which protrude perpendicularly over the anchor plate 1, for example, are arranged in pairs in the outer edge region of the anchor plate 1 along the outer edges of the anchor plate 1. Preferably in the corner regions of the anchor plate 1 projections in the form of ¾-arcs are shown, each of which centrally form a receptacle 6 for reinforcing steel 7. The reinforcing steels 7 can be arranged transversely or perpendicular to the anchor plate 1 in order to give the anchor device a spatial dimension, and are also referred to as projecting elements 5.

Bewehrungsstähle 7 unterschiedlicher Durchmesser sind vorzugsweise über Adapterstücke in die jeweils vorgesehene Aufnahme 6 der Ankerplatte 1 einsteckbar und sind mit der Ankerplatte 1 lösbar verbindbar. Alternativ oder zusätzlich definiert ein Vorsprungselement selbst eine Aufnahme für ein weiteres Vorsprungselement 7, wie beispielsweise in Fig. 2 dargestellt ist.Reinforcing steels 7 of different diameters are preferably inserted via adapter pieces in the respectively provided receptacle 6 of the anchor plate 1 and are detachably connectable to the anchor plate 1. Alternatively or additionally, a projection element itself defines a receptacle for a further projection element 7, such as in FIG Fig. 2 is shown.

Die erfindungsgemäße Ankervorrichtung erreicht durch das Ankerelement mit plattenförmiger Grundstruktur (Ankerplatte 1) bei entsprechender Einbindung im Beton 8 wesentlich höhere Auszugskräfte als die herkömmlichen Transportbügel. Durch die entsprechend dem Kräfteverlauf optimierte Konstruktion bzw. Geometrie der Ankerplatte 1 kann der Materialeinsatz optimiert werden.The anchor device according to the invention achieved by the anchor element with plate-shaped basic structure (anchor plate 1) with appropriate involvement in the concrete 8 much higher pull-out forces than the conventional transport bracket. By optimized according to the flow of force construction or geometry of the anchor plate 1, the use of materials can be optimized.

Die Geometrie der Ankerplatten 1 kann unterschiedlichste Formen aufweisen. Die Ankerplatte 1 kann aus Stahl geschmiedet, gestanzt, gegossen oder gekantet sein oder aus anderen Materialien, wie z.B. glasfaserhaltigen oder kohlefaserhaltigen Werkstoffen, gefertigt sein.The geometry of the anchor plates 1 can have a wide variety of shapes. The anchor plate 1 can be forged, stamped, cast or canted from steel, or made from other materials, such as steel. glass fiber-containing or carbon fiber-containing materials to be manufactured.

Die Ankervorrichtung gemäß dem ersten Ausführungsbeispiel, die in den Fig. 1 und 2 dargestellt ist, ist für mindestens zwei unterschiedliche (Doppel-)Wandstärken, z.B. 240 mm und 300 mm einsetzbar. Im Einbauzustand gemäß Fig. 1 ist die Längsmittelachse der Ankerplatte 1 parallel zu den Oberflächen der Betonwände angeordnet, und der Abstand der Betonwände 8 ist geringer als im Einbauzustand gemäß Fig. 2, wo die Längsmittelachse der Ankerplatte 1 senkrecht zu den Oberflächen der Betonwände angeordnet ist. Dieselbe Ankervorrichtung kann sowohl für zwei, oder bei Schrägstellung für mehrere Wandstärken eingesetzt werden, was die Lagerhaltung und auch die Stückkosten erheblich verringert. Eine Ankervorrichtung, bei welcher die Ankerplatte 1 einen oktogonalen Umriss aufweist, kann für noch mehrere Wandstärken eingesetzt werden. Bedingt durch die flächige Ausbildung der Ankervorrichtung kann diese darüber hinaus nicht nur als Abhebeanker genutzt werden, sondern auch zur Fixierung und Positionierung zweier Bauteile untereinander mit hoher Maßhaltigkeit, anstelle von Nadeln oder punktförmigen Ankern, gemäß dem Stand der Technik.The anchor device according to the first embodiment, which in the Fig. 1 and 2 is shown, can be used for at least two different (double) wall thicknesses, for example 240 mm and 300 mm. In the installed state according to Fig. 1 the longitudinal central axis of the anchor plate 1 is arranged parallel to the surfaces of the concrete walls, and the distance between the concrete walls 8 is lower than in the installed state according to Fig. 2 where the longitudinal central axis of the anchor plate 1 is arranged perpendicular to the surfaces of the concrete walls. The same anchor device can be used for two, or in inclined position for several wall thicknesses, which significantly reduces the inventory and also the unit cost. An anchor device, in which the anchor plate 1 has an octagonal outline, can be used for even more wall thicknesses. Due to the planar design of the anchor device, this can also be used not only as Abhebeanker, but also for fixing and positioning two components with each other with high dimensional accuracy, instead of needles or punctiform anchors, according to the prior art.

Die Ankervorrichtung wird dabei so ausgeführt, dass die Abschnitte, welche in die Betonplatten 8 einbinden, durch eine Erhöhung der Oberfläche bessere Haftung und somit höhere Auszugswerte erreichen. Dies wird durch Elemente bewerkstelligt, die im Rahmen dieser Erfindung generisch als Vorsprungselemente 5, 7 bezeichnet werden. Dies können Rippen, Wülste, Ausbauchungen, Wölbungen, Abkantungen, Aufdickungen, Prägungen oder Bewehrungselemente, wie Bewehrungsstähle, etc. sein. Zudem können die Auszugswerte durch das Einstecken der Bewehrungsstähle 7 oder anderen Verbundhilfen erhöht werden. Optional sind die Oberflächen der in die Betonplatten 8 einbindenden Abschnitte der Ankervorrichtung aufgeraut, beispielsweise durch Riffelung oder dgl..The anchor device is designed so that the sections which embed in the concrete slabs 8, by increasing the surface better adhesion and thus achieve higher pullout values. This is accomplished by elements generically referred to as protrusion elements 5, 7 in the context of this invention. These can be ribs, bulges, bulges, bulges, bends, thickenings, embossments or reinforcing elements, such as reinforcing bars, etc. In addition, the pull-out values can be increased by inserting the reinforcing steel 7 or other composite aids. Optionally, the surfaces of the sections of the anchoring device which engage in the concrete slabs 8 are roughened, for example by corrugation or the like.

Das Ausführungsbeispiel gemäß Fig. 2 umfasst ein Ankerelement 1 mit im Wesentlichen rechteckigem Umriss. Jeweils zwei diagonal gegenüberliegende Ecken des Ankerelements 1 sind zur gleichen Seite des Ankerelements 1 ca. 45° abgebogen, um Abkantungen auszubilden. Die in Fig. 2 dargestellte Ankervorrichtung umfasst vier kreuzförmig angeordnete und im Wesentlichen kreisförmige Eingriffsöffnungen 2 für Kranhaken und dergleichen. Zwischen den Eingriffsöffnungen 2 sind im Wesentlichen kreisförmige Ausnehmungen 3 vorgesehen, die der Gewichtseinsparung dienen und die Wärmeleitung durch die Ankerplatte 1 verringern. Daneben umfasst die Ankerplatte 1 weitere Ausnehmungen bzw. Öffnungen und Vorsprungselemente 5, um eine formschlüssige Verbindung zu den Bauteilen bzw. Betonwänden 8 zu bewerkstelligen.The embodiment according to Fig. 2 comprises an anchor element 1 with a substantially rectangular outline. In each case two diagonally opposite corners of the anchor member 1 are bent to the same side of the anchor member 1 about 45 ° to form bends. In the Fig. 2 illustrated anchor device comprises four cross-shaped and substantially circular engagement openings 2 for crane hooks and the like. Between the engagement openings 2 substantially circular recesses 3 are provided which serve the weight saving and reduce the heat conduction through the anchor plate 1. In addition, the anchor plate 1 comprises further recesses or openings and projection elements 5, in order to accomplish a positive connection to the components or concrete walls 8.

Bei bestimmungsgemäßem Gebrauch wird die erfindungsgemäße Ankervorrichtung derart in zwei Betonwände 8 eingebunden, dass sich die Betonwände 8 parallel zueinander und senkrecht zur Ankerplatte 1 erstrecken und mit der Ankervorrichtung einen doppelwandigen Transportverbund bilden. Dieser doppelwandige Transportverbund ist zum Transport durch eine Hebeeinrichtung (nicht dargestellt) vorgesehen, wobei ein Kranhaken der Hebeeinrichtung in die in Fig. 1 oben liegende Ausnehmung 2 in der Ankerplatte 1 eingehängt wird.When used as intended, the anchoring device according to the invention is incorporated into two concrete walls 8 in such a way that the concrete walls 8 extend parallel to one another and perpendicular to the anchor plate 1 and form a double-walled transport composite with the anchoring device. This double-walled transport composite is provided for transport by a lifting device (not shown), wherein a crane hook of the lifting device in the in Fig. 1 overhead recess 2 is suspended in the anchor plate 1.

Der doppelwandige Transportverbund kann auch mehrere erfindungsgemäße Ankervorrichtungen umfassen, welche die zwei Wände der Doppelwand auf Distanz halten und genau zueinander positionieren. Durch die Ausnehmungen 3 in der Ankerplatte 1 wird die Wärmedurchleitung durch die Ankerplatte 1, d.h. die Wärmedurchleitung durch die gesamte Doppelwand, minimiert, was für die bauphysikalischen Eigenschaften der Doppelwand im Hinblick auf Wärmeschutz und zur Vermeidung von Taupunktunterschreitungen durch Wärmebrücken von großer Bedeutung ist.The double-walled transport composite may also comprise a plurality of anchor devices according to the invention, which keep the two walls of the double wall at a distance and position each other exactly. Through the recesses 3 in the anchor plate 1, the heat transmission through the anchor plate 1, i. the heat transmission through the entire double wall, minimized, which is of great importance for the physical properties of the double wall in terms of thermal protection and to avoid dew point under thermal bridges.

Für den Fachmann ist offensichtlich, dass die Form und Größe der Ankervorrichtung, insbesondere der Ankerplatte, sowie die Form und Größe der gestalterischen Elemente, wie z. B. der Vorsprungselemente, variiert werden können.It is obvious to the person skilled in the art that the shape and size of the anchor device, in particular the anchor plate, as well as the shape and size of the design elements, such. B. the protrusion elements can be varied.
