Definitions
- the present invention relates to a transverse force mandrel bearing arrangement consisting of a transverse force mandrel, a transverse force mandrel bearing sleeve and at least one bearing basket holding the bearing sleeve, and also an end plate arranged to the side of the joint gap to be bridged.
- Shear force mandrels are connection and pressure distribution elements for two concrete components running in the same plane, which are separated from each other by a joint.
- a transverse force mandrel bearing which, as usual, consists of a transverse force mandrel, a transverse force mandrel bearing sleeve and a bearing basket holding the bearing sleeve.
- an end plate arranged to the side of the joint gap to be bridged in the form of four crosswise arranged tabs. This end plate is only used to fix the transverse force mandrel bearing sleeve to a casing during the creation of the concrete plate in which the bearing sleeve is cast.
- the storage basket consists of a number of closed loops made of reinforcing steel wires with a bent hook projecting inwards, in which the sleeve lies. The loops are therefore in planes parallel to the direction of the joint.
- EP-A-0'193'494 shows a variant developed further after the shear force mandrel mounting described above.
- the shear force bearing sleeve is held independently of the storage basket.
- an assembly shoe is fastened to a front formwork into which an end plate, which is firmly connected to the transverse force mandrel sleeve, can be inserted.
- a height-adjustable support rod is provided at the closed end of the transverse force mandrel bearing sleeve, which guarantees correct holding of the bearing sleeve during concreting.
- the end plate only has a holding function during concreting.
- the independent storage basket has corresponding steel rings, in which the sleeve and the transverse force mandrel are mounted on the one hand.
- shear force mandrel storage high-quality steel is available, by means of which the forces can be transferred without any problems, but the pressure limit for concrete is significantly exceeded in the area of the shear force mandrel or the shear force mandrel sleeve. This problem can be reduced by the number of transverse force mandrels is increased in the direction of the expansion joint, but this leads to considerable additional costs.
- a system from the company Perier and Partner is also known, in which two transverse force mandrels are arranged vertically one above the other.
- the risk of not exceeding the pressure limit of concrete as a result has been experimentally reduced by arranging anchoring bars arranged transversely to the direction of the two transverse force mandrel sleeves in a rib connecting them perpendicular to the direction of the transverse force mandrels.
- the increase in surface area achieved is relatively small, so that the problem mentioned is only slightly alleviated.
- a system from the Aschwanden company is also known, which provides that the transverse force mandrel is held on one side in a cup which is poured with high-quality concrete.
- the permissible pressure limit of the concrete is exceeded within the cup, but the force is transferred to the cup and the concrete running above the cup is relieved to such an extent that the permissible pressure limit is no longer exceeded here.
- the storage problem of the transverse force mandrel or the transverse force mandrel sleeve is considerably increased during installation.
- the area of the expansion joint F to be bridged lies in the area between the two parallel end plates 3, which lie flush in the end faces of the two concrete plates B to be connected.
- the two concrete slabs B are only shown in dashed lines, since the entire transverse force mandrel mounting is shown in this figure per se in the non-installed state.
- the transverse force mandrel mounting consists of two bearing baskets 10, 11, which are connected to one another only by a transverse force mandrel 1 bridging the joint F.
- the lateral force mandrel 1 is held in the left bearing basket 10 in the drawing and the lateral force mandrel bearing sleeve 2 is held in the bearing basket 11 shown on the right in the figure.
- the transverse force mandrel bearing sleeve 2 hereinafter also simply called the bearing sleeve, is drawn in section in the front part and in the rear part in the view.
- Each storage basket 10, 11 consists of two parts that are firmly connected to one another, namely the end plate 3 on the one hand and a steel band 4 on the other hand.
- the dimensions of the two end plates 3 are identical.
- the length 1 of each end plate 3 is less than the thickness of the concrete plate in which it is installed. However, it will preferably be made practically at least approximately as long as the thickness of the concrete slab.
- the width of the end plate 3 is designated by b.
- a steel band 4 is fastened to the end plate 3.
- This steel band 4 is attached to the end plate 3 on the side remote from the joint. This is preferably done Attachment by welding.
- the steel strip 4 is shown in its development in Figure 3.
- the width b 'of the steel strip 4 is slightly smaller than the width b of the end plate 3.
- the length of the steel strip is denoted by l'.
- a through hole 5 is punched, the diameter of which corresponds to the diameter of the transverse force mandrel or the diameter of the transverse force mandrel bearing sleeve 2, depending on whether the band 4 to the bearing basket 10, which holds the transverse force mandrel 1, or to the bearing basket 11, which Sleeve 2 carries, heard.
- the end plate 3 and the steel band 4 together form an approximately trapezoidal loop in the side view.
- the steel strips 4 thus have two legs 6 of equal length and inclined to one another, which are connected to one another by a section 7 which runs parallel to the respective end plate.
- the through holes 5 mentioned are arranged centrally in the respective sections 7.
- a plurality of vent holes 9 are provided in each leg 6 of the steel strip 4. This prevents 6 air pockets from forming under the legs when concreting in.
- connection of the steel strips 4 to the end plates 3 can be made by means of weld seams 8 along the longitudinal edges of the legs 6, as is shown in the storage basket 10.
- connection of the steel strips 4 to the end plates 3 can be made by means of weld seams 8 along the longitudinal edges of the legs 6, as is shown in the storage basket 10.
- the shear force mandrel 1 can be held in the bearing basket 10 in a form-fitting manner by a dimensionally accurate design of the through hole 5 in the central section 7 of the steel strip 4 and an equally dimensionally accurate implementation of the shear force mandrel 1 by the corresponding end plate 3.
- the transverse force mandrel bearing sleeve 2 is preferably attached to the bearing basket 11 in such a way that the sleeve 2 passes through the end plate 3 and is flush with the latter at the joint gap side.
- the corresponding through hole 30 is advantageously punched in the end plate 3. This creates a slightly tapered hole into which the sleeve 2 can be inserted.
- a conically tapering annular gap 31 remains between the sleeve 2 and the end plate 3, which facilitates the welding of the sleeve 2 and the end plate 3.
- the circumferential weld seam is applied on the side remote from the joint gap F.
- the weld seam itself is designated 32.
- the sleeve 2 is only passed through the steel strip 4, but not firmly connected to it.
- the advantage of the solution according to the invention is not only the simplicity of the construction, but it is also particularly advantageous statically. Thanks to the closed loop, which is formed by the end plate 3 and the steel band 4 on the other hand, a structurally highly resilient construction results. Furthermore, the compressive forces of the transverse force mandrel or the transverse force mandrel bearing sleeve 2 are optimally introduced into the respective end plate 3 on the one hand and into the steel strip 4 on the other hand. Thus, as the load-bearing surface of the transverse force mandrel or the transverse force mandrel bearing sleeve, not only their longitudinal sectional surface comes into play, but the entire width of the steel band 4 or the end plate 3, thereby preventing the permissible concrete pressure from being exceeded. Depending on the thickness of the concrete slabs and the loads to be transmitted, the width b of the end plate or the width b 'of the steel strips 4 and the transverse force mandrels are dimensioned accordingly.
- the end plate 3 is dimensioned such that its length 1 is greater than the base of the trapezoidal loop, so that nail holes 33 can be made in the free corner areas of the end plate. This simplifies the assembly of the storage baskets on the formwork of the slabs to be concreted.

Description
Die vorliegende Erfindung betrifft eine Querkraftdornlagerung bestehend aus einem Querkraftdorn, einer Querkraftdornlagerhülse sowie mindestens einem die Lagerhülse haltenden Lagerkorb, sowie ferner einer seitlich des zu überbrückenden Fugenspaltes angeordneten Stirnplatte.The present invention relates to a transverse force mandrel bearing arrangement consisting of a transverse force mandrel, a transverse force mandrel bearing sleeve and at least one bearing basket holding the bearing sleeve, and also an end plate arranged to the side of the joint gap to be bridged.
Querkraftdorne sind Verbindungs- und Druckverteilungselemente für zwei in der gleichen Ebene verlaufende Betonbauteile, die voneinander durch eine Fuge getrennt sind. Aus der EP-A-0'119'652 ist eine Querkraftdornlagerung bekannt, die wie üblich aus einem Querkraftdorn, einer Querkraftdornlagerhülse sowie einem die Lagerhülse haltenden Lagerkorb besteht. Ferner ist eine seitlich des zu überbrückenden Fugenspaltes angeordnete Stirnplatte in der Form von vier kreuzweise angeordneten Laschen vorhanden. Diese Stirnplatte dient lediglich der Fixierung der Querkraftdornlagerhülse an einer Verschalung während der Erstellung der Betonplatte, in der die Lagerhülse eingegossen wird. Der Lagerkorb besteht aus einer Anzahl geschlossener Schlaufen aus Armierungsstahldrähten mit einem nach innen ragenden abgebogenen Haken, in dem die Hülse liegt. Die Schlaufen liegen somit in Ebenen parallel zur Verlaufsrichtung der Fuge.Shear force mandrels are connection and pressure distribution elements for two concrete components running in the same plane, which are separated from each other by a joint. From EP-A-0'119'652 a transverse force mandrel bearing is known which, as usual, consists of a transverse force mandrel, a transverse force mandrel bearing sleeve and a bearing basket holding the bearing sleeve. Furthermore, there is an end plate arranged to the side of the joint gap to be bridged in the form of four crosswise arranged tabs. This end plate is only used to fix the transverse force mandrel bearing sleeve to a casing during the creation of the concrete plate in which the bearing sleeve is cast. The storage basket consists of a number of closed loops made of reinforcing steel wires with a bent hook projecting inwards, in which the sleeve lies. The loops are therefore in planes parallel to the direction of the joint.
Eine nach der vorher beschriebenen Querkraftdornlagerung weiterentwickelte Variante zeigt die EP-A-0'193'494. Bei dieser Ausführungsform erfolgt die Halterung der Querkraftdornlagerhülse unabhängig vom Lagerkorb. Hierzu wird an einer Stirnschalung ein Montageschuh befestigt, in den eine Stirnplatte, welche mit der Querkraftdornhülse fest verbunden ist, einschiebbar ist. Am geschlossenen Ende der Querkraftdornlagerhülse ist eine höhenverstellbare Abstützstange vorgesehen, die eine korrekte Halterung der Lagerhülse während des Einbetonierens garantiert. Auch hier hat die Stirnplatte lediglich eine Haltefunktion während des Einbetonierens. Der unabhängige Lagerkorb weist entsprechende Stahlringe aut, in denen einerseits die Hülse und andererseits der Querkraftdorn gelagert sind.EP-A-0'193'494 shows a variant developed further after the shear force mandrel mounting described above. In this embodiment, the shear force bearing sleeve is held independently of the storage basket. For this purpose, an assembly shoe is fastened to a front formwork into which an end plate, which is firmly connected to the transverse force mandrel sleeve, can be inserted. A height-adjustable support rod is provided at the closed end of the transverse force mandrel bearing sleeve, which guarantees correct holding of the bearing sleeve during concreting. Here, too, the end plate only has a holding function during concreting. The independent storage basket has corresponding steel rings, in which the sleeve and the transverse force mandrel are mounted on the one hand.
Neben diesen genannten Querkraftdornlagersystemen sind eine Vielzahl weiterer Querkraftdornlagerungen bekannt. Eines der wesentlichsten Probleme bei der Querkraftdornlagerung besteht darin, dass zwar hochwertiger Stahl vorhanden ist, mittels dem die auftretenden Kräfte problemlos übertragen werden können, doch wird im Bereich des Querkraftdornes bzw. der Querkraftdornlagerhülse die Druckgrenze für Beton wesentlich überschritten. Dieses Problem lässt sich zwar reduzieren, indem man die Anzahl der Querkraftdorne in der Verlaufsrichtung der Dehnungsfuge erhöht, doch führt dies zu erheblichen Mehrkosten.In addition to the aforementioned shear force bearing systems, a large number of other shear force bearing arrangements are known. One of the most important problems with the shear force mandrel storage is that high-quality steel is available, by means of which the forces can be transferred without any problems, but the pressure limit for concrete is significantly exceeded in the area of the shear force mandrel or the shear force mandrel sleeve. This problem can be reduced by the number of transverse force mandrels is increased in the direction of the expansion joint, but this leads to considerable additional costs.
Es ist ferner ein System der Firma Pflüger und Partner bekannt, bei dem jeweils zwei Querkraftdorne vertikal übereinander liegend angeordnet sind. Die Gefahr, die Druckgrenze von Beton hierdurch nicht mehr zu überschreiten, ist versuchsweise dadurch reduziert worden, dass quer zur Verlaufsrichtung der beiden Querkraftdornhülsen in einer sie verbindenden Rippe senkrecht zur Verlaufsrichtung der Querkraftdorne angeordnete Verankerungsstäbe angeordnet sind. Die dadurch erzielte Oberflächenvergrösserung ist jedoch relativ klein, so dass das erwähnte Problem nur geringfügig gemildert wird.A system from the company Pflüger and Partner is also known, in which two transverse force mandrels are arranged vertically one above the other. The risk of not exceeding the pressure limit of concrete as a result has been experimentally reduced by arranging anchoring bars arranged transversely to the direction of the two transverse force mandrel sleeves in a rib connecting them perpendicular to the direction of the transverse force mandrels. However, the increase in surface area achieved is relatively small, so that the problem mentioned is only slightly alleviated.
Es ist ferner ein System der Firma Aschwanden bekannt, welches vorsieht, dass jeweils der Querkraftdorn einseitig in einem Becher gehalten ist, der mit einem hochwertigen Beton vergossen ist. Innerhalb des Bechers wird dabei zwar auch die zulässige Druckgrenze des Betons überschritten, doch erfolgt die Kraftübertragung auf den Becher und der oberhalb des Bechers verlaufende Beton wird soweit entlastet, dass hier die zulässige Druckgrenze nicht mehr überschritten wird. Durch diese Anordnung wird jedoch das Lagerungsproblem des Querkraftdorns bzw. der Querkraftdornhülse während des Einbaues erheblich erhöht.A system from the Aschwanden company is also known, which provides that the transverse force mandrel is held on one side in a cup which is poured with high-quality concrete. The permissible pressure limit of the concrete is exceeded within the cup, but the force is transferred to the cup and the concrete running above the cup is relieved to such an extent that the permissible pressure limit is no longer exceeded here. With this arrangement, however, the storage problem of the transverse force mandrel or the transverse force mandrel sleeve is considerably increased during installation.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Querkraftdornlagerung gemäss Oberbegriff des Patentanspruches 1 zu schaffen, welche die vorerwähnten Probleme meidet.It is therefore the object of the present invention to provide a transverse force mandrel mounting according to the preamble of
Diese Aufgabe löst eine Querkraftdornlagerung mit den Merkmalen des Patentanspruches 1. Weitere vorteilhafte Ausgestaltungsformen des Erfindungsgegenstandes gehen aus den abhängigen Patentansprüchen hervor.This problem is solved by a transverse force mandrel bearing with the features of

Der zu überbrückende Bereich der Dehnungsfuge F liegt im Bereich zwischen den beiden parallelen Stirnplatten 3, die bündig in den Stirnflächen der beiden zu verbindenden Betonplatten B liegen. Die beiden Betonplatten B sind lediglich strichliniert dargestellt, da die gesamte Querkraftdornlagerung in dieser Figur an sich im nicht eingebauten Zustand dargestellt ist. Die Querkraftdornlagerung besteht aus zwei Lagerkörben 10,11, die lediglich durch einen, die Fuge F überbrückenden Querkraftdorn 1 miteinander in Verbindung stehen. In dem in der Zeichnung linken Lagerkorb 10 ist der Querkraftdorn 1 gehalten und im in der Figur rechts dargestellten Lagerkorb 11 ist die Querkraftdornlagerhülse 2 gehalten. Die Querkraftdornlagerhülse 2 nachfolgend auch einfach Lagerhülse genannt, ist im vorderen Teil im Schnitt und im hinteren Teil in der Ansicht gezeichnet.The area of the expansion joint F to be bridged lies in the area between the two
Jeder Lagerkorb 10,11 besteht aus zwei fest miteinander verbundenen Teilen, nämlich einerseits der Stirnplatte 3 und andererseits einem Stahlband 4. Die beiden Stirnplatten 3 sind in ihren Ausmessungen identisch. Die Länge 1 jeder Stirnplatte 3 ist geringer als die Dicke der Betonplatte, in der sie eingebaut wird. Vorzugsweise wird man sie jedoch praktisch mindestens annähernd so lang machen, wie es der Dicke der Betonplatte entspricht. Die Breite der Stirnplatte 3 ist mit b bezeichnet. An der Stirnplatte 3 befestigt ist ein Stahlband 4. Dieses Stahlband 4 ist auf der der Fuge abgelegenen Seite an der Stirnplatte 3 angebracht. Vorzugsweise erfolgt diese Befestigung mittels Schweissen. Das Stahlband 4 ist in seiner Abwicklung in der Figur 3 gezeigt. Die Breite b' des Stahlbandes 4 ist geringfügig kleiner als die Breite b der Stirnplatte 3. Die Länge des Stahlbandes ist mit l' bezeichnet. In der Mitte des Stahlbandes 4 ist ein Durchgangsloch 5 eingestanzt, dessen Durchmesser dem Durchmesser des Querkraftdornes oder dem Durchmesser der Querkraftdornlagerhülse 2 entspricht, je nachdem, ob das Band 4 zum Lagerkorb 10, welcher den Querkraftdorn 1 hält, oder zum Lagerkorb 11, der die Hülse 2 trägt, gehört.Each
In einer bevorzugten Ausführungsform bilden die Stirnplatte 3 und das Stahlband 4 zusammen eine in der Seitenansicht etwa trapezförmige Schlaufe. Die Stahlbänder 4 weisen somit zwei gleichlange, zueinander geneigt verlaufende Schenkel 6 auf, die durch einen Abschnitt 7 der parallel zur jeweiligen Stirnplatte verläuft, miteinander verbunden sind. Die erwähnten Durchgangslöcher 5 sind in den jeweiligen Abschnitten 7 zentrisch angeordnet. In jedem Schenkel 6 des Stahlbandes 4 sind mehrere Entlüftungslöcher 9 angebracht. Hierdurch wird vermieden, dass beim Einbetonieren unter den Schenkeln 6 Lufteinschlüsse entstehen können.In a preferred embodiment, the
Die Verbindung der Stahlbänder 4 mit den Stirnplatten 3 kann mittels Schweissnähten 8 entlang den Längskanten der Schenkel 6 erfolgen, wie dies beim Lagerkorb 10 dargestellt ist. Es ist jedoch auch möglich, an den Schenkeln 6 endseitig je einen Umbug 12 vorzusehen, so dass die Schweissverbindung zwischen der Stirnplatte 3 und dem Stahlband 4 durch Punktschweissung erfolgen kann.The connection of the
Die Halterung des Querkraftdornes 1 im Lagerkorb 10 kann formschlüssig erfolgen durch eine massgenaue Gestaltung des Durchgangsloches 5 im mittleren Abschnitt 7 des Stahlbandes 4 und einer ebenso massgenauen Durchführung des Querkraftdornes 1 durch die entsprechende Stirnplatte 3. Es ist jedoch auch möglich, zusätzlich den Querkraftdorn 1 entweder mit dem Stahlband 4 oder der Stirnplatte 3 oder mit beiden Teilen zu fixieren. Eine solche Fixierung kann beispielsweise durch eine Klebung oder eine Punktschweissung erfolgen.The
Die Befestigung der Querkraftdornlagerhülse 2 am Lagerkorb 11 erfolgt vorzugsweise so, dass die Hülse 2 die Stirnplatte 3 durchsetzt und mit dieser zur Fugenspaltseite hin bündig abschliesst. Dies geht am deutlichsten aus der Figur 2 hervor. Hierzu wird vorteilhafterweise das entsprechende Durchgangsloch 30 in der Stirnplatte 3 gestanzt. Hierdurch entsteht ein leicht konisch verlaufendes Loch, in welches die Hülse 2 hineingesteckt werden kann. So verbleibt zwischen der Hülse 2 und der Stirnplatte 3 ein konisch zulaufender Ringspalt 31, der die Verschweissung von Hülse 2 und Stirnplatte 3 erleichtert. Die umlaufende Schweissnaht wird dabei auf der dem Fugenspalt F abgelegenen Seiten angebracht. Die Schweissnaht selber ist mit 32 bezeichnet. Die Hülse 2 ist durch das Stahlband 4 lediglich hindurchgeführt, jedoch nicht mit diesem fest verbunden.The transverse force
Der Vorteil der erfindungsgemässen Lösung besteht nicht nur in der Einfachheit der Konstruktion, sondern sie ist auch statisch besonders vorteilhaft. Dank der geschlossenen Schlaufe, welche durch die Stirnplatte 3 und das Stahlband 4 andererseits gebildet ist, ergibt sich eine statisch hochbelastbare Konstruktion. Ferner werden die Druckkräfte des Querkraftdornes bzw. der Querkraftdornlagerhülse 2 in optimaler Weise einerseits in die jeweilige Stirnplatte 3 und andererseits in das Stahlband 4 eingeleitet. Damit kommt als tragende Fläche des Querkraftdornes beziehungsweise der Querkraftdornlagerhüle nicht allein deren Längsschnittfläche zum Tragen, sondern die gesamte Breite des Stahlbandes 4 bzw. der Stirnplatte 3, wodurch die Ueberschreitung des zulässigen Betondruckes vermieden wird. Je nach der Dicke der Betonplatten und der somit zu übertragenden Lasten wird die Breite b der Stirnplatte beziehungsweise die Breite b' der Stahlbänder 4 sowie der Querkraftdorne entsprechend dimensioniert.The advantage of the solution according to the invention is not only the simplicity of the construction, but it is also particularly advantageous statically. Thanks to the closed loop, which is formed by the
Schliesslich wird man die Stirnplatte 3 so bemessen, dass ihre Länge 1 grösser als die Basis der trapezförmigen Schlaufe gestaltet ist, so dass in den freien Eckbereichen der Stirnplatte Nagellöcher 33 angebracht werden können. Dies vereinfacht die Montage der Lagerkörbe an den Verschalungen der zu betonierenden Platten.Finally, the
