Description

Die Erfindung betrifft ein Querkraftdornlager, insbesondere für ein Treppenpodest, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a transverse force mandrel bearing, in particular for a stair landing, according to the preamble of claim 1.

Es ist bekannt, beispielsweise ein Treppenpodest schwimmend in den Wänden eines Treppenhauses zu lagern, indem mehrere Querkraftdornlager verwendet werden, die eine Relativbewegung zwischen dem Treppenpodest und dem Treppenhaus in Längsrichtung der Querkraftdorne ermöglichen, jedoch die vertikalen Verkehrslasten zuverlässig übertragen.It is known, for example, to store a stairway floating in the walls of a staircase by using several transverse force mandrel bearings which allow relative movement between the stair landing and the staircase in the longitudinal direction of the shear force mandrels but reliably transmit the vertical traffic loads.

Wie die EP-A 0 716 192 zeigt, ist ein derartiger Querkraftdorn eines Querkraftdornlagers sowohl in dem feststehenden Bauteil, d.h. dem Treppenhaus, als auch dem schwimmend gelagerten Treppenpodest in einer rohrförmigen Hülse verschieblich aufgenommen. Während die Hülse in das feststehende Bauteil direkt eingegossen ist, ist in dem Treppenpodest eine spezielle Ausgestaltung eines Querkraftdornlagers vorgesehen, das primär der Lastabtragung aus dem Treppenpodest über den Querkraftdorn und zusätzlich der Schalldämmung dient. Die den Querkraftdorn aufnehmende Hülse ist auf eine Lastverteilungsplatte aufgeschweißt, die sich unter Zwischenschaltung einer federnden, dämmenden Kunststoffplatte am Boden eines Lagergehäuses abstützt, die zur Erfüllung der Dämpfungsfunktion korrekt dimensioniert sein muß. Die Wände des Gehäuses sind innenseitig mit dünnen schalldämmenden Platten ausgekleidet, die im Vergleich zur Kunststoffplatte wesentlich weicher sind. Der im Inneren des Gehäuses verbleibende Freiraum insbesondere um die Hülse herum ist mit einem Füllmaterial ausgefüllt. Auf diese Weise werden Querkräfte über den Querkraftdorn, die Hülse und die Lastverteilungsplatte unter elastischer Abfederung und Dämmung mittels der Kunststoffplatte in das Gehäuse und von diesem in das umgebende Bauteil eingeleitet. Jedoch ist der konstruktive Aufbau relativ aufwendig und es kann insbesondere das Problem auftreten, dass aufgrund des Schweißvorganges zwischen der Hülse und der Lastverteilungsplatte in dieser ein Verzug auftritt, so daß sie nicht mehr gleichmäßig auf der darunterliegenden Kunststoffplatte aufliegt, wodurch es zu einer ungleichmäßigen Einleitung von Lasten in die Kunststoffplatte und somit zu einer ungleichmäßigen Federwirkung kommt.As EP-A 0 716 192 shows, such a transverse force mandrel of a transverse force mandrel bearing is displaceably received in a tubular sleeve in both the stationary component, ie the staircase, and the floating stair landing. While the sleeve is cast directly into the fixed component, a special embodiment of a transverse force mandrel bearing is provided in the stair landing, the primary of the load transfer from the landing over the shear force mandrel and in addition the sound insulation serves. The sleeve receiving the lateral force mandrel is welded onto a load distribution plate, which is supported by a resilient, insulating plastic plate at the bottom of a bearing housing, which must be correctly dimensioned to fulfill the damping function. The walls of the housing are lined on the inside with thin sound-absorbing plates, which are much softer compared to the plastic plate. The remaining space inside the housing, in particular around the sleeve, is filled with a filling material. In this way, transverse forces are introduced via the transverse force mandrel, the sleeve and the load distribution plate under elastic cushioning and insulation by means of the plastic plate in the housing and from this into the surrounding component. However, the structural design is relatively expensive and it may in particular the problem occur that due to the welding process between the sleeve and the load distribution plate in this a delay occurs, so that it no longer rests evenly on the underlying plastic plate, resulting in a non-uniform introduction of Loads in the plastic plate and thus leads to an uneven spring action.

Um eine gute Kraftübertragung zwischen dem Querkraftdorn und der Hülse zu gewährleisten, sollte der Querkraftdorn spielfrei und somit unter enger Passung in der Hülse sitzen. Dies ist jedoch in der Praxis nicht zu erreichen, da sich dann der Querkraftdorn nicht oder nur unter Aufbringung sehr großer Axialkräfte in die Hülse einschieben läßt. Darüber hinaus treten sowohl bei der Hülse auch bei dem Querkraftdorn Maßtoleranzen auf, die eine spielfreie Aufnahme des Querkraftdorns in der Hülse unmöglich machen. Um den Querkraftdorn bei der Montage in einfacher Weise in die Hülse einführen zu können, wird üblicherweise ein ausreireichendes Spiel zwischen dem Querkraftdorn und der Hülse vorgesehen. Dies bringt jedoch die Gefahr mit sich, dass der Querkraftdorn sich innerhalb der Hülse verschiebt, was insbesondere dann passieren kann, wenn in unmittelbarer Nähe des Querkraftdornlagers Beton durch sogenanntes Rütteln, d.h. Einbringen von Schwingungen, verdichtet wird. Es hat sich gezeigt, dass der Querkraftdorn aufgrund dieser Schwingungen seine Lage innerhalb der Hülse stark verändern und sogar aus dieser herausrutschen kann. Bei einer Verlagerung des Querkraftdorns innerhalb der Hülse verändert sich die ursprünglich vorhandene Lastabtragungsfläche, wodurch sich auch die Spannungsverhältnisse innerhalb des Querkraftdornlagers verändern, was nachteilig ist.In order to ensure a good power transmission between the shear force mandrel and the sleeve, the shear force mandrel should sit backlash-free and thus close in the sleeve. However, this can not be achieved in practice, since then can not insert the shear force mandrel or only with the application of very large axial forces in the sleeve. In addition, dimensional tolerances occur both in the sleeve and in the transverse force mandrel, which make a play-free recording of the transverse force mandrel in the sleeve impossible. In order to introduce the shear force mandrel during assembly in a simple manner in the sleeve, is usually a sufficient Game provided between the shear force mandrel and the sleeve. However, this entails the risk that the shear force mandrel shifts within the sleeve, which can happen especially when in the immediate vicinity of the shear force mandrel bearing concrete by so-called shaking, ie introducing vibrations, is compressed. It has been found that the shear force mandrel due to these vibrations can greatly change its position within the sleeve and even slip out of it. With a displacement of the transverse force mandrel within the sleeve, the originally existing load transfer surface changes, which also change the stress conditions within the shear force mandrel bearing, which is disadvantageous.

Während gemäß der EP-A 0 716 192 im normalen Gebrauchszustand aufgrund der Lastverteilungsplatte von einer definierten Lastabtragung innerhalb des Querkraftdornlagers ausgegangen wird, sieht das Querkraftdornlager gemäß der DE-A 1 659 187 eine schwimmende Lagerung des Querkraftdorns vor. Zu diesem Zweck steht der Querkraftdorn nach seinem Einsetzen in das Querkraftdornlager auf seinen vier Seitenflächen jeweils mit einer Lagerplatte in Anlage. Die Lagerplatten sind unabhängig voneinander über jeweils eine "elastische Masse" an einer der Innenwandungen des Lagergehäuses abgestützt. Dies führt dazu, dass die Lagerplatten infolge der Federkraft der jeweiligen elastischen Masse an den Seitenflächen des Querkraftdorns anliegen und der Querkraftdorn sich entgegen der Federkräfte der elastischen Massen innerhalb des Querkraftdornlagers frei schwimmend bewegen kann.While according to EP-A 0 716 192 in the normal state of use due to the load distribution plate is based on a defined load transfer within the transverse force mandrel bearing, the transverse force mandrel bearing according to DE-A 1 659 187 provides for a floating mounting of the transverse force mandrel. For this purpose, the transverse force mandrel is after its insertion in the transverse force mandrel bearing on its four side surfaces each with a bearing plate in abutment. The bearing plates are supported independently of each other via one "elastic mass" on one of the inner walls of the bearing housing. This causes the bearing plates abut due to the spring force of the respective elastic mass on the side surfaces of the transverse force mandrel and the shear force mandrel can move freely against the spring forces of the elastic masses within the transverse force mandrel bearing.

Da eine derartig große Beweglichkeit des Querkraftdornlagers beispielsweise bei einem Treppenpodest in der Praxis nicht akzeptabel ist, besitzt das Querkraftdornlager gemäß der DE-A 1 659 187 vier Gegenlager aus Stahl, die jeweils in den Ecken des Querkraftdorns angeordnet sind. Sobald der Querkraftdorn sich um ein vorbestimmtes Maß aus seiner Mittellage wegbewegt, legt er sich an zumindest eines der Gegenlager an. Auf diese Weise ist jedoch bei diesem Querkraftdornlager eine definierte Lastabtragung nicht zu erzielen und in dem Anlagebereich zwischen dem Querkraftdorn und dem kontaktierten Gegenlager treten Spannungsspitzen auf, die nachteilig sind. Darüber hinaus ist der Aufbau des Querkraftdornlagers aufgrund der Notwendigkeit der stählernen Gegenlager relativ aufwendig und das Querkraftdornlager besitzt den weiteren Nachteil, dass die Querschnittsform der Querkraftdorns auf die Formgebung der Gegenlager abgestimmt sein muss.Since such a large mobility of the transverse force mandrel bearing is not acceptable in practice, for example, in a stair landing, has the transverse force mandrel bearing according to DE-A 1 659 187 four counter bearing made of steel, each are arranged in the corners of the shear force mandrel. As soon as the lateral force mandrel moves away from its central position by a predetermined amount, it attaches itself to at least one of the abutments. In this way, however, in this Querkraftdornlager a defined load transfer can not be achieved and in the contact area between the shear force mandrel and the contacted abutment voltage peaks occur, which are disadvantageous. In addition, the structure of the transverse force mandrel bearing is relatively expensive due to the need of the steel abutment and the Querkraftdornlager has the further disadvantage that the cross-sectional shape of the shear force mandrel must be matched to the shape of the counter bearing.

Der Erfindung liegt die Aufgabe zugrunde, ein Querkraftdörnlager der eingangs genannten Art zu schaffen, das bei einem konstruktiv einfachen Aufbau gute Lastabtragungs- und Dämmeigenschaften besitzt und eine sichere Halterung des Querkraftdorns gewährleistet.The invention has for its object to provide a Querkraftdörnlager of the aforementioned type which has good load transfer and insulation properties in a structurally simple structure and ensures a secure mounting of the transverse force mandrel.

Diese Aufgabe wird erfindungsgemäß mit einem Querkraftdornlager mit den Merkmalen des Anspruchs 1 gelöst. Dabei ist vorgesehen, dass die Aufnahme zumindest abschnittsweise von einer Ausnehmung in einem die Füllung bildenden formstabilen Formteil gebildet ist, das aus Gummi oder einem elastischen Kunststoff, insbesondere einem Elastomer, besteht, und dass auf den Innenwänden der Ausnehmung Führungsleisten für den Querkraftdorn angeordnet sind.This object is achieved with a Querkraftdornlager with the features of claim 1. It is provided that the receptacle is at least partially formed by a recess in a filling forming dimensionally stable molded part, which consists of rubber or an elastic plastic, in particular an elastomer, and that are arranged on the inner walls of the recess guide rails for the transverse force mandrel.

Erfindungsgemäß ist auf eine spezielle Hülse zur Aufnahme des Querkraftdorns verzichtet, so dass auch die mit dem Aufschweißen der Hülse auf die Lastverteilungsplatte einhergehenden Probleme bei der erfindungsgemäßen Ausgestaltung vermieden sind. Statt in der Hülse ist der Querkraftdorn bei dem erfindungsgemäßen Querkraftdornlager in der Ausnehmung des formstabilen elastischen Formteils aufgenommen, das vorzugsweise aus Gummi oder einem elastischen Kunststoff, beispielsweise einem Elastomer besteht. Das Formteil füllt den verbleibenden Freiraum im Inneren des Gehäuses zumindest annähernd vollständig aus; wodurch ein großes schallschluckendes Volumen gegeben ist und sich insgesamt sehr gute Dämmwerte des Querkraftdornlagers erreichen lassen.According to the invention, a special sleeve for receiving the transverse force mandrel is dispensed with, so that the problems associated with the welding of the sleeve to the load distribution plate in the embodiment according to the invention are also avoided. Instead of in the sleeve of the transverse force mandrel in the transverse force mandrel bearing according to the invention in the Received recess of the dimensionally stable elastic molding, which preferably consists of rubber or an elastic plastic, such as an elastomer. The molding fills the remaining space in the interior of the housing at least approximately completely; whereby a large sound-absorbing volume is given and can be achieved on the whole very good insulation values of the lateral force mandrel bearing.

Das Formteil ist in bekannter Weise in einem kastenartigen Gehäuse aufgenommen, wobei auf dem Boden des kastenartigen Gehäuses eine elastische Platte aufliegt, die von einer Lastverteilungsplatte zumindest teilweise überdeckt ist.The molded part is accommodated in a known manner in a box-like housing, wherein on the bottom of the box-like housing rests an elastic plate which is at least partially covered by a load distribution plate.

Um ein leichtes Einsetzen des Querkraftdorns zu gewährleisten, sind auf den Innenwänden der Ausnehmung Führungsleisten angeordnet. Beim Einschieben des Querkraftdorns kommt dieser mit den Führungsleisten in Anlage. Die Führungsleisten vermindern die Reibung zwischen dem Querkraftdorn und dem die Ausnehmung bildenden Formteil bei der Längsverschiebung des Querkraftdorns, wodurch Zwängungskräfte vermieden sind, und stellen darüber hinaus sicher, dass bei eventuellen Längsbewegungen des Querkraftdorns im eingebauten Zustand das elastische Material des umgebenden Formteils keiner übermäßigen Abnutzung unterliegt.To ensure easy insertion of the shear force mandrel, guide rails are arranged on the inner walls of the recess. When inserting the shear force mandrel comes this with the guide rails in plant. The guide rails reduce the friction between the shear force mandrel and the recess forming the molding in the longitudinal displacement of the shear force mandrel, whereby constraining forces are avoided, and also ensure that in case of any longitudinal movements of the shear force mandrel when installed the elastic material of the surrounding molding is not subject to excessive wear ,

Die Führungsleisten bestehen aus einem härteren Material als das Formteil, beispielsweise aus Metall und insbesondere aus Stahl, und dienen darüber hinaus als Lastverteiler bei am Querkraftdorn auftretenden, quer zu seiner Längserstreckung gerichteten Belastungen.The guide rails are made of a harder material than the molded part, for example made of metal and in particular of steel, and also serve as a load distributor when occurring at the shear force mandrel, directed transversely to its longitudinal loads.

Es hat sich gezeigt, dass die Kombination von einerseits dem elastischen Material des die Aufnahme definierenden Formteils und andererseits den Führungsleisten auf den Innenflächen der Ausnehmung ein einfaches Einschieben des Querkraftdorns in die Ausnehmung ermöglicht. Dabei kann insbesondere vorgesehen sein, dass der Querkraftdorn unter elastischer Aufweitung der Ausnehmung und somit des Formteils in die Ausnehmung einführbar ist, wodurch im eingesetzten Zustand des Querkraftdorns erreicht ist, dass die Führungsleisten aufgrund der Federwirkung des elastischen Materials von außen gegen die Querkraftdorn gespannt sind und diesen unter radial nach innen gerichteter Vorspannung und somit unter enger Passung in der Ausnehmung haltern.It has been shown that the combination of on the one hand the elastic material of the receptacle defining the molding and the other hand, the guide rails on the inner surfaces the recess allows a simple insertion of the transverse force mandrel in the recess. It can be provided in particular that the transverse force mandrel with elastic expansion of the recess and thus of the molded part is inserted into the recess, which is achieved in the inserted state of the transverse force mandrel that the guide rails are stretched due to the spring action of the elastic material from the outside against the transverse mandrel and support them under radially inwardly directed bias and thus close fit in the recess.

In einer möglichen Ausgestaltung der Erfindung kann vorgesehen sein, dass die Aufnahme auf allen Seiten, d.h. in allen Richtungen radial zum Querkraftdorn von dem Formteil begrenzt ist. In diesem Fall ist der Querkraftdorn allseitig über die Führungsleisten abgestützt und geführt. Alternativ ist es jedoch auch möglich, dass die Aufnahme auf zumindest zwei gegenüberliegenden Seiten und insbesondere auf drei Seiten von dem Formteil begrenzt ist.In a possible embodiment of the invention it can be provided that the recording on all sides, i. is limited in all directions radially to the shear force mandrel of the molded part. In this case, the shear force mandrel is supported and guided on all sides by the guide rails. Alternatively, however, it is also possible that the receptacle is delimited on at least two opposite sides and in particular on three sides of the molded part.

Das Formteil kann die auf den Boden des Gehäuses aufliegende elastische Platte und die darüberliegende Lastverteilungsplatte umhüllen und an den Seitenwänden, der Decke und der Rückwand des Gehäuses vollflächig aufliegen, wodurch die Dämpfwirkung verbessert ist.The molded part can envelop the resilient plate lying on the bottom of the housing and the overlying load distribution plate and rest on the side walls, the ceiling and the rear wall of the housing over the entire surface, whereby the damping effect is improved.

In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, dass die Ausnehmung direkt oberhalb der Lastverteilungsplatte angeordnet und zu dieser hin offen ist. Auf diese Weise ist die Aufnahme für den Querkraftdorn von den drei Innenwänden der Ausnehmung und der Oberfläche der darunterliegenden Lastverteilungsplatte begrenzt. Der Querkraftdorn liegt direkt auf der Lastverteilungsplatte auf, so dass an ihm auftretende, vertikale Querkräfte über direkten Kontakt mit der Lastverteilungsplatte in diese eingeleitet werden.In a preferred embodiment of the invention it is provided that the recess is arranged directly above the load distribution plate and open to this. In this way, the receptacle for the shear force mandrel is bounded by the three inner walls of the recess and the surface of the underlying load distribution plate. The lateral force mandrel rests directly on the load distribution plate, so that vertical transverse forces occurring on it are introduced into this via direct contact with the load distribution plate.

Die Ausnehmung, in der der Querkraftdorn unter enger Passung und radial nach innen gerichteter Verspannung durch das elastisch verformte Formteil aufgenommen ist, stellt die korrekte Position des Querkraftdorns sicher und hält diesen in der vorbestimmten Lage. Die Querschnittsform der Ausnehmung ist an den Querschnitt des Querkraftdorns angepasst, wobei der Querkraftdorn in der Regel einen Rechteck-, Quadrat- oder Kreisquerschnitt besitzt und die Ausnehmung entweder mit einem entsprechenden kreisförmigen Querschnitt oder insbesondere mit einem im wesentlichen rechteckigen bzw. quadratischen Querschnitt ausgebildet ist. Ein quadratischer Querschnitt des Querkraftdorns besitzt ein hohes Widerstandsmoment und eine großflächige Auflage auf der Lastverteilungsplatte. Wenn die Ausnehmung einen quadratischen Querschnitt besitzt, kann sie sowohl einen Querkraftdorn mit einem ebenfalls quadratischen Querschnitt als auch einen Querkraftdorn mit einem Kreisquerschnitt aufnehmen.The recess, in which the shear force mandrel is received under tight fit and radially inwardly directed tension by the elastically deformed molding, ensures the correct position of the shear force mandrel and keeps it in the predetermined position. The cross-sectional shape of the recess is adapted to the cross section of the transverse force mandrel, wherein the transverse force mandrel usually has a rectangular, square or circular cross-section and the recess is formed either with a corresponding circular cross section or in particular with a substantially rectangular or square cross section. A square cross-section of the shear force mandrel has a high modulus and a large-scale support on the load distribution plate. If the recess has a square cross-section, it can accommodate both a shear force mandrel with a square cross section as well as a transverse force mandrel with a circular cross section.

Vorzugsweise sind alle Innenwände der Ausnehmung mit Führungsleisten versehen, die bei einem rechteckigen Querschnitt in einem gegenseitigen Winkelversatz in Umfangsrichtung von ca. 90° angeordnet sind. Die Führungsleisten können sich über die gesamte Länge der Ausnehmung erstrecken, in der Regel dürfte es jedoch ausreichen, wenn die Führungsleisten sich über einen Teilbereich der Ausnehmung und vorzugsweise etwa zwei Drittel der Länge erstrecken. Die Führungsleisten können an ihrem der offenen Vorderseite des Gehäuses zugewandten Ende abgeflacht sein, wodurch die Ausnehmung einen sich trichterförmig erweiternden Querschnitt bekommt, der ein einfaches Einschieben des Querkraftdorns ermöglicht.Preferably, all inner walls of the recess are provided with guide strips, which are arranged at a rectangular cross-section in a mutual angular offset in the circumferential direction of approximately 90 °. The guide rails may extend over the entire length of the recess, but in general it should be sufficient if the guide rails extend over a portion of the recess and preferably about two-thirds of the length. The guide rails can be flattened at their end facing the open front of the housing end, whereby the recess gets a funnel-shaped widening cross section, which allows easy insertion of the shear force mandrel.

Im eingebauten Zustand schaut der Querkraftdorn an einem Ende aus der Aufnahme hervor. Das entgegengesetzte Ende der Aufnahme ist üblicherweise durch das Formteil und gegebenenfalls das umgebende Gehäuse geschlossen. In Weiterbildung der Erfindung kann jedoch vorgesehen sein, dass die Aufnahme an ihren entgegengesetzten Enden offen ist, so dass der Querkraftdorn auch vom hinteren axialen Ende bzw. von beiden entgegengesetzten axialen Enden der Aufnahme in diese eingeführt werden kann. Dies ist insbesondere dann sinnvoll, wenn das vordere Ende der Aufnahme nur schwer zugänglich ist. Nachdem der Querkraftdorn in die Aufnahme eingeführt ist, sollte das hintere Ende der Aufnahme verschlossen werden, was beispielsweise mittels eines Stopfens erreicht werden kann.When installed, the shear force mandrel looks out of the receptacle at one end. The opposite end of the receptacle is usually through the molding and optionally the surrounding housing closed. In a further development of the invention, however, it can be provided that the receptacle is open at its opposite ends, so that the transverse force mandrel can also be introduced from the rear axial end or from both opposite axial ends of the receptacle in this. This is particularly useful if the front end of the recording is difficult to access. After the shear force mandrel is inserted into the receptacle, the rear end of the receptacle should be closed, which can be achieved for example by means of a plug.

Üblicherweise liegt der Querkraftdorn mit seiner Unterseite auf der Lastverteilungsplatte auf. Falls die über das Querkraftdornlager zu verbindenden Bauteile jedoch Wechselbelastungen ausgesetzt sind, kann es auch passieren, dass der Querkraftdorn von der unteren Lastverteilungsplatte abgehoben wird. Um den Querkraftdorn auch in diesem Zustand zuverlässig zu lagern, kann auch auf der der unteren Lastverteilungsplatte entgegengesetzten Seite ein stabiles Lager ausgebildet sein, das vorzugsweise ebenfalls eine elastische Platte aufweist, die auf ihrer dem Querkraftdorn zugewandten Seite von einer Lastverteilungsplatte zumindest teilweise überdeckt ist.Usually, the shear force mandrel lies with its underside on the load distribution plate. However, if the components to be connected via the shear force mandrel bearing are subjected to alternating loads, it may also happen that the shear force mandrel is lifted off the lower load distribution plate. In order to store the lateral force mandrel reliably in this state, a stable bearing can also be formed on the side opposite the lower load distribution plate, which preferably also has an elastic plate which is at least partially covered by a load distribution plate on its side facing the lateral force mandrel.

Ein in den Fig. 1 und 2 dargestelltes Querkraftdornlager 10 umfaßt ein kastenartiges Gehäuse 11, das in eine Aussparung eines nicht dargestellten Bauteils eingesetzt oder in dieses eingegossen werden kann. Das Gehäuse 11 ist an seiner Vorderseite offen und besitzt vier seitlich in verschiedene Richtungen hervorstehende Flansche 12, mit denen es an der Schalung des Bauteils bei dessen Herstellung angebracht werden kann. Die vier Flansche stützen das Gehäuse beim Betoniervorgang sicher an der Schalung ab und verhindern insbesondere ein Verrutschen des Gehäuses beim Verdichten des Betons.A shown in FIGS. 1 and 2 transverse force mandrel bearing 10 comprises a box-like housing 11 which can be inserted into a recess of a component, not shown, or poured into this. The housing 11 is open at its front and has four laterally projecting in various directions flanges 12, with which it can be attached to the formwork of the component in its manufacture. The four flanges support the housing safely during the concreting process on the formwork and in particular prevent slippage of the housing when compacting the concrete.

Auf dem Boden 11a des Gehäuses 11 liegt eine elastische Platte 13 auf, die aus einem schwingungsdämpfenden, hochfesten,Kunststoff besteht, wie er in der Lagertechnologie an sich bekannt ist. Dabei handelt es sich vorzugsweise um ein unbewehrtes Elastomer, wobei die elastische Platte in ihrer Abmessung speziell auf die abzutragende Last so dimensioniert ist, dass sich eine gute Schwingungsisolation ergibt. Die elastische Platte 13 ist auf ihrer Oberseite von einer Lastverteilungsplatte 14 vollständig überdeckt, die aus einem gegenüber der elastischen Platte 13 härteren Material, beispielsweise Stahl besteht.On the floor 11a of the housing 11 is an elastic plate 13, which consists of a vibration-damping, high-strength, plastic, as it is known per se in the storage technology. It is preferably an unreinforced elastomer, wherein the elastic plate is dimensioned in its dimension specifically to the abzutragende load so that there is a good vibration isolation. The elastic plate 13 is completely covered on its upper side by a load distribution plate 14, which consists of a relative to the elastic plate 13 harder material, such as steel.

Der verbleibende Freiraum im Inneren des Gehäuses 11 ist von einem formstabilen Form- oder Füllteil 15 ausgefüllt, das aus Gummi oder einem elastischen Kunststoff besteht. Wie Fig. 1 zeigt, liegt das Formteil 15 an den Seitenwänden 11b und der Decke 11c des Gehäuses 11 vollflächig an. In dem Formteil 15 ist direkt oberhalb der Lastverteilungsplatte 14 eine Ausnehmung 15a ausgebildet, die zu der Lastverteilungsplatte 14 hin offen ist und mit dieser eine hülsenartige Aufnahme 16 für einen Querkraftdorn 18 bildet. Die Ausnehmung 15 besitzt einen rechteckigen Querschnitt, wobei auf den Innenwänden der Ausnehmung 15a in deren Längsrichtung verlaufende Führungsleisten 17 angeordnet sind, die aus einem härteren Material als das Formteil 15 und insbesondere aus Stahl bestehen.The remaining space inside the housing 11 is filled by a dimensionally stable forming or filling part 15, which is made of rubber or an elastic plastic. As shown in Fig. 1, the molded part 15 is located on the side walls 11b and the ceiling 11c of the housing 11 over the entire surface. In the molded part 15, a recess 15a is formed directly above the load distribution plate 14, which is open to the load distribution plate 14 and forms with this a sleeve-like receptacle 16 for a transverse force mandrel 18. The recess 15 has a rectangular cross section, wherein on the inner walls of the recess 15a extending in the longitudinal direction guide rails 17 are arranged, which consist of a harder material than the molded part 15 and in particular of steel.

Wie Fig. 2 zeigt, erstreckt sich die Ausnehmung 15a nicht über die gesamte Tiefe des Formteils 15 und somit des Gehäuses 11, sondern am hinteren Ende des Formteils 15 verbleibt ein Rückenteil 15b, mit dem das Formteil 15 vollflächig an der Rückwand 11d des Gehäuses 11 anliegt.As shown in FIG. 2, the recess 15a does not extend over the entire depth of the molded part 15 and thus of the housing 11, but at the rear end of the molding 15 remains a back portion 15b, with which the molding 15 over the entire surface of the rear wall 11d of the housing eleventh is applied.

Der Querkraftdorn 18 lässt sich von der Vorderseite der Ausnehmung 15a bzw. des Querkraftdornlagers 10 in die Aufnahme 16 unter elastischer Aufweitung des die Ausnehmung 15a bildenden Formteils 15 einschieben, wobei er mit seiner Unterseite direkt auf der Lastverteilungsplatte 14 liegt und auf beiden Seiten sowie oben mit den Führungsleisten 17 der Aufnahme 16 in Anlage steht. Der Querkraftdorn 18 ist längsverschieblich in der Aufnahme 16 aufgenommen und in dieser durch die sich aus der elastischen Verformung des Formteils 15 ergebenden radial nach innen gerichteten Spannkräfte gehalten. Mit seinem aus der Aufnahme 16 axial hervorstehenden Ende greift der Querkraftdorn in an sich bekannter, hier nicht dargestellter Weise in eine Aufnahme eines Querkraftdornlagers eines anderen Bauteils ein.The transverse force mandrel 18 can be inserted from the front of the recess 15a and the Querkraftdornlagers 10 in the receptacle 16 under elastic expansion of the recess 15a forming molding 15, wherein it lies directly with its underside on the load distribution plate 14 and on both sides and top with the guide rails 17 of the receptacle 16 is in contact. The transverse force mandrel 18 is received longitudinally displaceable in the receptacle 16 and held in this by the resulting from the elastic deformation of the molding 15 radially inwardly directed clamping forces. With its axially projecting from the receptacle 16 end of the transverse force mandrel engages in a known per se, not shown here manner in a recording of a shear force mandrel bearing of another component.

Fig. 3 zeigt eine alternative Ausgestaltung des Querkraftdornlagers 10 gemäß den Fig. 1 und 2. Während bei dem Ausführungsbeispiel gemäß Fig. 2 die Aufnahme 16 nur auf der Vorderseite, auf der der Querkraftdorn 18 hervorsteht, offen ist, ist die Aufnahme 16 bei der Ausführungsform gemäß Fig. 3 an ihren beiden axialen Enden offen, wodurch es möglich ist, dass der Querkraftdorn 18 am hinteren, d.h. gemäß Fig. 3 linken Ende der Aufnahme 16 in die Aufnahme 16 eingeschoben wird, bis er am vorderen Ende aus dieser hervorsteht. Das hintere Ende der Aufnahme 16 kann dann mittels eines deckelartigen Verschlussstopfens 19, der eine in die Aufnahme 16 axial einführbare Nase 19a aufweist, verschlossen werden.3 shows an alternative embodiment of the transverse force mandrel bearing 10 according to FIGS. 1 and 2. While in the embodiment of FIG. 2, the receptacle 16 only on the front side on which the transverse mandrel 18 protrudes, is open, the receptacle 16 in the Embodiment according to FIG. 3 at its two axial ends open, whereby it is possible that the transverse force mandrel 18 at the rear, ie 3 left end of the receptacle 16 is inserted into the receptacle 16 until it protrudes from the front end of this. The rear end of the receptacle 16 can then be closed by means of a cover-like sealing plug 19, which has a nose 19a axially insertable into the receptacle 16.

Bei dem in den Fig. 1 bis 3 dargestellten Ausführungsbeispiel liegt der Querkraftdorn 18 auf seiner Unterseite auf der Lastverteilungsplatte 14 auf, während er seitlich und oberhalb durch das die Aufnahme 16 bildende Formteil 15 gehalten ist. Die Fig. 4 und 5 zeigen eine Abwandlung des Ausführungsbeispiels gemäß Fig. 1, wobei auch hier der Querkraftdorn 18 auf der Oberseite der Lastverteilungsplatte 14 aufliegt, die ihrerseits die elastische Platte 13 überdeckt. Zusätzlich ist jedoch auf der Oberseite des Querkraftdorns 18 eine an der Decke 11c des Gehäuses 11 abgestützte elastische Platte 13 vorgesehen, die auf ihrer dem Querkraftdorn 18 zugewandten Seite mit einer Lastverteilungsplatte 14 überdeckt ist. Auf diese Weise ist die Aufnahme 16 auf ihrer Oberseite und ihrer Unterseite durch je weils eine Lastverteilungsplatte 14 begrenzt, während die verbleibenden Seiten der Aufnahme 16 vom Formteil 15 begrenzt sind, wobei auch hier auf den die Aufnahme 16 begrenzenden Innenwandungen des Formteils 15 jeweils eine Führungsleiste 17 angeordnet ist. Mit der in den Fig. 4 und 5 dargestellten Ausgestaltung lassen sich nicht nur vertikal nach unten gerichtete Kräfte über den Querkraftdorn 18 zuverlässig abtragen, sondern eine gute Lastabtragung ist auch gewährleistet, wenn am Querkraftdorn 18 vertikal nach oben gerichtete Querkräfte wirksam sind.In the embodiment shown in FIGS. 1 to 3 of the transverse force mandrel 18 is on its underside on the load distribution plate 14, while it is held laterally and above by the receptacle 16 forming mold part 15. 4 and 5 show a modification of the embodiment of FIG. 1, wherein here also the transverse force mandrel 18 rests on the upper side of the load distribution plate 14, which in turn covers the elastic plate 13. In addition, however, on the top of the transverse force mandrel 18, a supported on the ceiling 11c of the housing 11 elastic plate 13 is provided, which is covered on its side facing the shear force mandrel 18 with a load distribution plate 14. In this way, the receptacle 16 is limited on its top and bottom by each case a load distribution plate 14, while the remaining sides of the receptacle 16 are limited by the molding 15, wherein here on the recording 16 limiting inner walls of the molding 15 each have a guide bar 17 is arranged. With the embodiment shown in FIGS. 4 and 5, not only vertically downwardly directed forces on the transverse force mandrel 18th Relieve reliable, but a good load transfer is also guaranteed if the transverse force mandrel 18 vertically upward transverse forces are effective.
