Description

Vorrichtung zum Verbinden von zwei durch eine Fuge getrennte Bauteile und zur Aufnahme von zwischen den Bauteilen auftretenden Querkräften  Device for connecting two components separated by a joint and for absorbing transverse forces occurring between the components
Technisches Gebiet Technical area
Die vorliegende Erfindung betrifft eine Vorrichtung zum Verbinden von zwei durch eine Fuge getrennte Bauteile und zur Aufnahme von zwischen den Bauteilen auftretenden Querkräften. The present invention relates to a device for connecting two components separated by a joint and for absorbing transverse forces occurring between the components.
Stand der Technik State of the art
Querkraftdorne sind Verbindungs- und Druckverteilungselemente für zwei in der gleichen Ebene verlaufende Betonbauteile, die voneinander durch eine Fuge getrennt sind. Transverse force mandrels are connection and pressure distribution elements for two in the same plane running concrete components, which are separated from each other by a joint.
Aus dem Stand der Technik sind Querkraftdorne bekannt, die Relativbewegungen von Gebäudeteilen in nur einer Richtung erlauben, aber auch Dorne, die eine Relativbewegung in zwei Richtungen gestatten. Bei dem in Figur 1 dargestellten ersten Fall werden die in einem ersten Gebäudeteil verankerten, in der Regel zylindrischen Querkraftdorne 1 von einer konzentrischen, im zweiten Gebäudeteil verankerten zylindrischen Hülse 2 aufgenommen. Mit dem Bezugszeichen 4 sind Bohrungen bezeichnet, die der Befestigung der Hülse an der Schalung durch Nägel oder Schrauben dienen. Der Dorn 1 kann sich lediglich entlang der Längsachse der zylindrischen Hülse 2 bewegen, wodurch Bewegungen in nur einer Richtung (a- Richtung) möglich sind. Querkraftdorne are known from the prior art, which allow relative movements of building parts in only one direction, but also mandrels, which allow a relative movement in two directions. In the first case illustrated in FIG. 1, the lateral force mandrels 1, which are anchored in a first part of the building and are generally cylindrical, are received by a concentric cylindrical sleeve 2 anchored in the second part of the building. By the reference numeral 4 holes are designated, which serve to attach the sleeve to the formwork by nails or screws. The mandrel 1 can only move along the longitudinal axis of the cylindrical sleeve 2, whereby movements in only one direction (a-direction) are possible.
Sollen Bewegungen in zwei Richtungen erlaubt sein, so wird der zylindrische Dorn 1 wie in Figur 2 dargestellt beispielsweise von einer als Hohlquader ausgebildeten Hülse 3 aufgenommen, wobei die Ausdehnung der Hülse 3 in c-Richtung im Wesentlichen dem Durchmesser des Dorns 1 entspricht. In diesem Fall kann der Dorn 1 zum einen in Richtung seiner Längsachse (a-Richtung) in die Hülse eindringen, es sind aber auch horizontale Bewegungen des Dorns senkrecht zu seiner Längsachse (b-Richtung) möglich. If movements in two directions are to be allowed, the cylindrical mandrel 1, as shown in FIG. 2, is received, for example, by a sleeve 3 designed as a hollow cuboid, the extension of the sleeve 3 in the c direction in FIG Substantially corresponds to the diameter of the mandrel 1. In this case, the mandrel 1 on the one hand in the direction of its longitudinal axis (a-direction) penetrate into the sleeve, but it is also horizontal movements of the mandrel perpendicular to its longitudinal axis (b-direction) possible.
Aus der EP 1 19 652 A2 ist eine Querkraftdornlagerung bekannt, die aus einem Querkraftdorn, einer Querkraftdornlagerhülse sowie einem die Lagerhülse und den Dorn haltenden Lagerkorb besteht. Ferner ist eine seitlich des zu überbrückenden Fugenspaltes angeordnete Stirnplatte in Form von vier kreuzweise angeordneten Laschen vorgesehen. Diese Stirnplatte dient 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 Ebene der Stirnplatte und parallel zur Verlaufsrichtung der Fuge. From EP 1 19 652 A2, a transverse force mandrel bearing is known which consists of a transverse force mandrel, a transverse force mandrel bearing sleeve and a bearing cage holding the bearing sleeve and the mandrel. Further, a laterally arranged to be bridged joint gap face plate in the form of four cross tabs is provided. This face plate is used to fix the shear force mandrel bearing sleeve to a shuttering during the preparation of the concrete slab, in which the bearing sleeve is poured. The storage basket consists of a number of closed loops of reinforcing steel wires with an inwardly bent hook in which the sleeve is located. The loops are thus in planes parallel to the plane of the face plate and parallel to the direction of the joint.
Die EP 193 494 A1 beschreibt eine Querkraftdornlagerung, bei der die Halterung der Querkraftdornlagerhülse unabhängig vom Lagerkorb erfolgt. 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 auf, in denen einerseits die Hülse und andererseits der Querkraftdorn gelagert sind. EP 193 494 A1 describes a transverse force mandrel bearing in which the support of the transverse force mandrel bearing sleeve takes place independently of the bearing basket. For this purpose, a mounting shoe is attached to an end formwork, in which a front plate, which is fixedly connected to the Querkraftdornhülse, can be inserted. At the closed end of the Querkraftdornlagerhülse a height-adjustable support rod is provided, which guarantees a correct mounting of the bearing sleeve during Einbetonierens. Again, the face plate has only a holding function during Einbetonierens. The independent storage basket has corresponding steel rings in which on the one hand the sleeve and on the other hand the transverse force mandrel are mounted.
Ein Verbindungs- und Druckverteilerelement für zwei durch eine Fuge voneinander getrennte Betonbauteile ist in der EP 554 483 A1 beschrieben. Das Element weist einen die Fuge überbrückenden Verbindungsbolzen, eine Gleithülse, ein dem Verbindungsbolzen zugeordnetes Bügelelement, ein zweites, der Gleithülse zugeordnetes Bügelelement und eine Halteplatte für die Gleithülse auf. Aus der EP 814 213 B1 ist eine Querkraftdornlagerung bestehend aus einem Querkraftdorn, einer Querkraftdornlagerhülse sowie einem die Lagerhülse haltenden Lagerkorb bekannt. Beidseits des zu überbrückenden Fugenspaltes sind Stirnplatten aus rostfreiem Stahl angeordnet, die jeweils zusammen mit einem Band aus rostfreiem Stahl eine senkrecht zur Fugenverlaufsrichtung angeordnete, einen Lagerkorb bildende Schlaufe formen. Jeweils eine Stirnplatte bildet zusammen mit einem Stahlband eine in der Seitenansicht etwa trapezförmige Schlaufe, deren Basis durch die Stirnplatte gebildet wird. Die aus der EP 814 213 B1 bekannte Querkraftdornlagerung weist zwar eine relativ gute statische Belastbarkeit auf, ist aber mit einem hohen Materialaufwand verbunden. A connection and pressure distribution element for two concrete components separated by a joint is described in EP 554 483 A1. The element has a connection bolt bridging the joint, a sliding sleeve, a stirrup element assigned to the connecting pin, a second stirrup element associated with the sliding sleeve and a retaining plate for the sliding sleeve. From EP 814 213 B1, a transverse force mandrel bearing is known consisting of a transverse force mandrel, a transverse force mandrel bearing sleeve and a bearing cage holding the bearing cage. Both sides of the joint gap to be bridged face plates are arranged stainless steel, each forming together with a band of stainless steel arranged perpendicular to the direction of the joint, forming a storage basket loop. In each case, an end plate together with a steel strip in a side view approximately trapezoidal loop whose base is formed by the face plate. Although known from EP 814 213 B1 Querkraftdornlagerung has a relatively good static load capacity, but is associated with a high cost of materials.
Es besteht daher weiter ein Bedarf an statisch gut belastbaren und mit möglichst geringem Materialaufwand herzustellenden Verbindungs- und Druckverteilungselementen für Betonbauteile. There is therefore still a need for statically good load and produced with the least possible cost of materials connection and pressure distribution elements for concrete components.
Darstellung der Erfindung Hier setzt die Erfindung an. Es soll eine Vorrichtung zum Verbinden von zwei durch eine Fuge getrennte Bauteile und zur Aufnahme von zwischen den Bauteilen auftretenden Querkräften zur Verfügung gestellt werden, die eine gute statische Belastbarkeit aufweist und gleichzeitig mit einem relativ geringen Materialaufwand hergestellt werden kann. Diese Aufgabe wird erfindungsgemäß durch die Vorrichtung zum Verbinden von zwei durch eine Fuge getrennte Bauteile und zur Aufnahme von zwischen den Bauteilen auftretenden Querkräften gemäß unabhängigem Patentanspruch 1 gelöst. Weitere vorteilhafte Aspekte, Details und Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen, der Beschreibung sowie den Zeichnungen. DESCRIPTION OF THE INVENTION The invention starts here. It should be made available a device for connecting two components separated by a joint and for receiving transverse forces occurring between the components, which has a good static load capacity and can be produced simultaneously with a relatively low cost of materials. This object is achieved by the device for connecting two separate components by a joint and for receiving occurring between the components transverse forces according to independent claim 1. Further advantageous aspects, details and embodiments of the invention will become apparent from the dependent claims, the description and the drawings.
Die erfindungsgemäße Vorrichtung zum Verbinden von zwei durch eine Fuge getrennte Bauteile, nämlich eines dornseitigen Bauteils und eines hülsenseitigen Bauteils, und zur Aufnahme von zwischen den Bauteilen auftretenden Querkräften umfasst einen Dorn, eine Hülse, ein den Dorn im Wesentlichen formschlüssig umgreifendes dornseitiges Kraftumlenkelement sowie zumindest einen dornseitigen Verankerungsbügel. Der dornseitige Verankerungsbügel weist einen Schlaufenabschnitt und zwei Endabschnitte auf, wobei der dornseitige Verankerungsbügel in seinem Schlaufenabschnitt das dornseitige Kraftumlenkelement im Wesentlichen formschlüssig umschlingt und die zur Verankerung im Beton vorgesehenen Endabschnitte des dornseitigen Verankerungsbügels im eingebauten Zustand von der Fuge weg in Richtung des dornseitigen Bauteils verlaufen. Besonders bevorzugt verlaufen die zur Verankerung im Beton vorgesehenen Endabschnitte des dornseitigen Verankerungsbügels im eingebauten Zustand im Wesentlichen senkrecht zur Fugenebene von der Fuge weg in Richtung des dornseitigen Bauteils. The device according to the invention for connecting two components separated by a joint, namely a mandrel-side component and a sleeve-side component, and for receiving transverse forces occurring between the components comprises a mandrel, a sleeve, a substantially form-locking the mandrel encompassing mandrel-side force deflecting element and at least one mandrel-side anchoring bracket. The mandrel-side anchoring bow has a loop portion and two end portions, wherein the mandrel-side anchoring bow in its loop portion, the mandrel-side Kraftumlenkelement wraps around substantially form-fitting and provided for anchoring in concrete end portions of the mandrel-side anchoring bracket in the installed state of the joint away in the direction of the mandrel-side component. In the installed state, the end sections of the arbor-side anchoring bracket provided in the concrete for anchoring are particularly preferably run substantially perpendicular to the joint plane away from the joint in the direction of the mandrel-side component.
Die erfindungsgemäße Vorrichtung weist im Vergleich zu den aus dem Stand der Technik bekannten Lösungen eine deutlich verbesserte statische Belastbarkeit auf. Gleichzeitig kann die erfindungsgemäße Vorrichtung mit einem vergleichsweise geringen Materialaufwand hergestellt werden. Das dornseitige Kraftumlenkelement weist einen Durchmesser auf, der es erlaubt einen einfachen Bewehrungsbügel soweit zu biegen, dass er das dornseitige Kraftumlenkelement im Wesentlichen formschlüssig umschlingt. Das dornseitige Kraftumlenkelement kann fest mit dem Dorn verbunden, insbesondere verschweißt oder verklebt sein. Es kann aber auch ohne feste Verbindung im Wesentlichen formschlüssig um den Dorn gelegt sein. The device according to the invention has a significantly improved static load capacity compared to the solutions known from the prior art. At the same time, the device according to the invention can be produced with a comparatively low cost of materials. The mandrel-side force deflecting element has a diameter which allows a simple reinforcing bar to bend so far that it wraps around the mandrel-side force deflecting element substantially in a form-fitting manner. The mandrel-side force deflecting element can be firmly connected to the mandrel, in particular welded or glued. But it can also be placed without a fixed connection substantially form-fitting manner around the mandrel.
Eine weitere Materialeinsparung kann erreicht werden, wenn bei der Dimensionierung der Verankerungsbügel beachtet wird, dass die auftretenden Querkräfte mit zunehmendem Abstand der beiden zu verbindenden Bauteile, also mit zunehmender Fugengröße, abnehmen. Mit zunehmender Fugengröße kann also der Querschnitt der Verankerungsbügel vermindert und damit zusätzliches Material eingespart werden. Denkbar ist sogar, dass der Querschnitt der Verankerungsbügel soweit verringert werden kann, dass Stahlseile als Verankerungsbügel eingesetzt werden können. Der Begriff „Verankerungsbügel" soll im Rahmen der vorliegenden Erfindung also auch Verankerungselemente umfassen, die aufgrund ihrer Dimensionierung auch als „Verankerungsseile" bezeichnet werden könnten. Vor dem Einbetonieren der erfindungsgemäßen Vorrichtung wird der dornseitige Verankerungsbügel an der bauseitigen Bewehrung angerödelt und so fest fixiert. Eine Fixierung der erfindungsgemäßen Vorrichtung kann auch durch eine Fixierung des Dorns in der Hülse erfolgen. Dazu wird die Hülse mit einer Sicke oder Ähnlichem versehen, so dass der Dorn nicht mehr aus der Hülse rutschen kann. Bei ausreichender Fixierung der Hülse wird damit auch die erfindungsgemäße Vorrichtung sicher befestigt. A further material saving can be achieved if, when dimensioning the anchoring bracket, it is ensured that the transverse forces which occur decrease with increasing distance between the two components to be connected, ie with increasing joint size. With increasing joint size so the cross section of the anchoring bracket can be reduced and thus additional material can be saved. It is even conceivable that the cross section of the anchoring bracket can be reduced so far that steel cables can be used as anchoring bracket. In the context of the present invention, the term "anchoring bracket" should therefore also include anchoring elements which, on account of their dimensioning, could also be referred to as "anchoring cables". Before setting in concrete of the device according to the invention, the arbor-side anchoring bracket is rooted on the on-site reinforcement and fixed so firmly. A fixation of the device according to the invention can also be done by a fixation of the mandrel in the sleeve. For this purpose, the sleeve is provided with a bead or the like, so that the mandrel can not slip out of the sleeve. With sufficient fixation of the sleeve so that the inventive device is securely attached.
In ihrer allgemeinsten Form ist die erfindungsgemäße Vorrichtung für die Verbindung zweier Bauteile geeignet, von denen nur das dornseitige Bauteil in einer vorbestimmten Richtung statisch belastet wird. Dies ist beispielsweise beim Anschluss eines Treppenpodestes an eine Wand der Fall. Die Hülse ist in dieser Ausführungsform in die Wand eingebaut, während Dorn, dornseitiges Kraftumlenkelement und dornseitiger Verankerungsbügel in das Treppenpodest einbetoniert werden. Das Treppenpodest wird ausschließlich in einer vorbestimmten Richtung statisch belastet. Die dabei auftretenden Querkräfte werden über den dornseitigen Verankerungsbügel in den Beton des Treppenpodestes eingeleitet. In its most general form, the device according to the invention is suitable for the connection of two components, of which only the arbor-side component is statically loaded in a predetermined direction. This is the case, for example, when connecting a stair landing to a wall. The sleeve is installed in this embodiment in the wall, while mandrel, mandrel-side force deflecting element and mandrel-side anchoring bracket are concreted into the stair landing. The stair landing is statically loaded only in a predetermined direction. The resulting shear forces are introduced via the mandrel-side anchoring bracket in the concrete of the landing.
Vorteilhafterweise ist der dornseitige Verankerungsbügel im eingebauten Zustand so fixiert, dass sein Schlaufenabschnitt relativ zu einer gedachten, von den zur Verankerung im Beton vorgesehenen Endabschnitten des dornseitigen Verankerungsbügels aufgespannten Ebene, in Richtung der statischen Belastung des Bauteils orientiert ist, in das Dorn, dornseitiges Kraftumlenkelement und dornseitiger Verankerungsbügel eingebaut sind. Wirkt also eine vertikal nach unten gerichtete Kraft auf das Bauteil, so befindet sich der Schlaufenabschnitt unterhalb der durch die beiden Endabschnitte des dornseitigen Verankerungsbügels aufgespannten Ebene. Die auf das dornseitige Bauteil vertikal nach unten wirkende Belastung wird auf diese Weise nach oben in das Bauteil eingeleitet. Gemäß einer bevorzugten Ausführungsform umfasst die Vorrichtung zusätzlich ein die Hülse im Wesentlichen formschlüssig umgreifendes hülsenseitiges Kraftumlenkelement sowie zumindest einen hülsenseitigen Verankerungsbügel aufweisend einen Schlaufenabschnitt und zwei Endabschnitte. Der hülsenseitige Verankerungsbügel umschlingt in seinem Schlaufenabschnitt das hülsenseitige Kraftumlenkelement im Wesentlichen formschlüssig. Die zur Verankerung im Beton vorgesehenen Endabschnitte des hülsenseitigen Verankerungsbügels verlaufen im eingebauten Zustand von der Fuge weg in Richtung des hülsenseitigen Bauteils. Besonders bevorzugt verlaufen die zur Verankerung im Beton vorgesehenen Endabschnitte des hülsenseitigen Verankerungsbügels im eingebauten Zustand im Wesentlichen senkrecht zur Fugenebene von der Fuge weg in Richtung des hülsenseitigen Bauteils. Advantageously, the mandrel-side anchoring bracket is fixed in the installed state that its loop portion is oriented relative to an imaginary, provided by the anchoring in the concrete end portions of the mandrel-side anchoring bracket plane oriented in the direction of the static load of the component in the mandrel, mandrel-side force deflecting and thornseitiger anchoring bracket are installed. Thus acts a vertically downward force on the component, so the loop portion is below the plane defined by the two end portions of the mandrel-side anchoring bracket plane. The load acting vertically downward on the mandrel-side component is introduced in this way upwards into the component. According to a preferred embodiment, the device additionally comprises a sleeve-side force deflecting element enclosing the sleeve substantially in a form-fitting manner, and at least one sleeve-side anchoring clip comprising a loop section and two end sections. The sleeve-side anchoring bracket wraps in its loop portion of the sleeve side Kraftumlenkelement substantially positive. The provided for anchoring in concrete end portions of the sleeve-side anchoring bracket extend in the installed state of the joint away in the direction of the sleeve-side member. In the installed state, the end sections of the sleeve-side anchoring bracket which are provided for anchoring in the concrete are particularly preferably run substantially perpendicular to the joint plane away from the joint in the direction of the sleeve-side component.
Das hülsenseitige Kraftumlenkelement kann fest mit der Hülse verbunden, insbesondere verschweißt oder verklebt sein. Sie kann aber auch ohne feste Verbindung im Wesentlichen formschlüssig um die Hülse gelegt sein. The sleeve-side force deflection element can be firmly connected to the sleeve, in particular welded or glued. But it can also be placed without a fixed connection substantially form-fitting manner around the sleeve.
In dieser bevorzugten Ausführungsform ist die Vorrichtung für die Verbindung zweier Bauteile geeignet, die beide in jeweils einer vorbestimmten Richtung statisch belastet werden. Dies ist beispielsweise beim Anschluss zweier Betonplatten im Straßenbau der Fall. Hülse, hülsenseitiges Kraftumlenkelement und hülsenseitiger Verankerungsbügel sind in die hülsenseitige Betonplatte eingebaut, während Dorn, dornseitiges Kraftumlenkelement und dornseitiger Verankerungsbügel in die dornseitige Betonplatte einbetoniert werden. Beide Betonplatten werden ausschließlich in einer vorbestimmten Richtung statisch belastet. Die dabei auftretenden Querkräfte werden über die Verankerungsbügel in den Beton der beiden Platten eingeleitet. In this preferred embodiment, the device is suitable for the connection of two components, both of which are statically loaded in each case in a predetermined direction. This is the case, for example, when connecting two concrete slabs in road construction. Sleeve, sleeve-side force deflecting element and sleeve-side anchoring bracket are installed in the sleeve-side concrete slab, while mandrel, mandrel-side force deflecting element and mandrel-side anchoring bracket are concreted into the mandrel-side concrete slab. Both concrete slabs are statically loaded exclusively in a predetermined direction. The resulting shear forces are introduced via the anchoring brackets in the concrete of the two plates.
Vorteilhafterweise ist der hülsenseitige Verankerungsbügel im eingebauten Zustand so fixiert, dass sein Schlaufenabschnitt relativ zu einer gedachten, von den zur Verankerung im Beton vorgesehenen Endabschnitten des hülsenseitigen Verankerungsbügels aufgespannten Ebene, in Richtung der statischen Belastung des hülsenseitigen Bauteils orientiert ist, in das Hülse, hülsenseitiges Kraftumlenkelement und hülsenseitiger Verankerungsbügel eingebaut sind. Wirkt also eine vertikal nach unten gerichtete Kraft auf das Bauteil, so befindet sich der Schlaufenabschnitt unterhalb der durch die beiden Endabschnitte des hülsenseitigen Verankerungsbügels aufgespannten Ebene. Die auf das Bauteil vertikal nach unten wirkende Belastung wird auf diese Weise nach oben in das Bauteil eingeleitet. Vor dem Einbetonieren der Vorrichtung wird der hülsenseitige Verankerungsbügel an der bauseitigen Bewehrung angerödelt und so fest fixiert. Besonders bevorzugt sind sowohl die dornseitigen Verankerungsbügel wie auch die hülsenseitigen Verankerungsbügel in der beschriebenen Orientierung eingebaut. Advantageously, the sleeve-side anchoring bracket is fixed in the installed state that its loop portion is oriented relative to an imaginary, provided by the anchoring in the concrete end portions of the sleeve side anchoring bracket plane in the direction of the static load of the sleeve-side component, in the sleeve, sleeve-side force deflection and sleeve side anchoring bracket are installed. Thus acts a vertically downward force on the component, so the loop portion is below the plane defined by the two end portions of the sleeve-side anchoring bracket plane. The load acting vertically downwards on the component is thus introduced upwards into the component. Before setting in the device of the sleeve-side anchoring bracket is rooted on the on-site reinforcement and fixed so firmly. Particularly preferably, both the mandrel-side anchoring brackets and the sleeve-side anchoring brackets are installed in the orientation described.
Gemäß einer besonders bevorzugten Ausführungsform umfasst die Vorrichtung zwei dornseitige Verankerungsbügel. Die beiden dornseitigen Verankerungsbügel umschlingen in ihren Schlaufenabschnitten das dornseitige Kraftumlenkelement im Wesentlichen formschlüssig, wobei die beiden dornseitigen Verankerungsbügel gegensinnig zueinander um das dornseitige Kraftumlenkelement geführt sind. According to a particularly preferred embodiment, the device comprises two mandrel-side anchoring brackets. The two mandrel-side anchoring brackets enclose in their loop sections the mandrel-side force deflecting element essentially in a form-fitting manner, wherein the two mandrel-side anchoring brackets are guided in opposite directions around the mandrel-side force deflecting element.
Besonders bevorzugt verlaufen die Endabschnitte der beiden dornseitigen Verankerungsbügel im Wesentlichen senkrecht zur Fugenebene von der Fuge weg und im Wesentlichen parallel zueinander. Die Endabschnitte führen in diesem Fall besonders weit in den Ortbeton hinein und sorgen so für eine sichere Verankerung. Particularly preferably, the end portions of the two mandrel-side anchoring brackets are substantially perpendicular to the joint plane away from the joint and substantially parallel to each other. The end sections lead in this case particularly far into the in-situ concrete and thus ensure a secure anchoring.

Hülse, hülsenseitiges Kraftumlenkelement und hülsenseitiger Verankerungsbügel sind in dem hülsenseitigen Bauteil eingebaut, welches ausschließlich in einer Richtung statisch belastet wird, während Dorn, dornseitiges Kraftumlenkelement und die beiden dornseitigen Verankerungsbügel in das dornseitige Bauteil einbetoniert werden, welches in zwei einander entgegengesetzten Richtungen statischen Belastungen ausgesetzt werden kann. Die bei einer statischen Belastung auftretenden Querkräfte werden über die Verankerungsbügel in den Beton der beiden Bauteile eingeleitet. In this embodiment, the device is suitable for the connection of two components, of which the sleeve-side component is statically loaded exclusively in a predetermined direction, while the arbor-side component can be subjected to static loads in two opposite directions. Sleeve, sleeve-side force deflecting element and sleeve-side anchoring bracket are installed in the sleeve-side component, which is statically loaded exclusively in one direction, while mandrel, mandrel-side force deflecting element and the two mandrel anchoring brackets are embedded in the mandrel component, which are exposed to static loads in two opposite directions can.

Statische Belastungen des entsprechenden Bauteils können bei einer solchen Orientierung der dornseitigen Verankerungsbügel besonders gut in das Bauteil eingeleitet werden. Preferably, the two mandrel-side anchoring brackets are oriented in opposite directions to each other, ie the reversal points of the loop portions of the two anchoring brackets lie on a straight line which is substantially perpendicular to the end portions of the mandrel-side anchoring bracket runs. Static loads of the corresponding component can be introduced particularly well into the component in such an orientation of the mandrel-side anchoring bracket.

Besonders bevorzugt verlaufen die Endabschnitte der beiden hülsenseitigen Verankerungsbügel im eingebauten Zustand im Wesentlichen senkrecht zur Fugenebene von der Fuge weg und im Wesentlichen parallel zueinander. Die Endabschnitte führen in diesem Fall besonders weit in den Ortbeton hinein und sorgen so für eine sichere Verankerung. Particularly preferably, the end portions of the two sleeve-side anchoring brackets in the installed state are substantially perpendicular to the joint plane away from the joint and substantially parallel to each other. The end sections lead in this case particularly far into the in-situ concrete and thus ensure a secure anchoring.

In beliebiger Richtung auftretende statische Belastungen des entsprechenden Bauteils können bei einer solchen Orientierung der Verankerungsbügel besonders gut in das Bauteil eingeleitet werden. Gemäß einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung umfasst die Vorrichtung zusätzlich zwei beidseits der zu überbrückenden Fuge angeordnete Stirnplatten, nämlich eine dornseitige Stirnplatte und eine hülsenseitige Stirnplatte. Ganz besonders bevorzugt ist (sind) der (die) dornseitige(n) Verankerungsbügel fest an der der Fuge abgewandten Seite der dornseitigen Stirnplatte mit der dornseitigen Stirnplatte verbunden und insbesondere bevorzugt ist (sind) auch der (die) hülsenseitige(n) Verankerungsbügel fest an der der Fuge abgewandten Seite der hülsenseitigen Stirnplatte mit der hülsenseitigen Stirnplatte verbunden.

Die Stirnplatten bestehen bevorzugt aus einem korrosionsbeständigen Material. Üblicherweise werden die Stirnplatten aus Edelstahl gefertigt, sie können aber auch aus Kunststoff bestehen. The end plates are preferably made of a corrosion-resistant material. Usually, the end plates are made of stainless steel, but they can also be made of plastic.
Bevorzugt ist der Dorn als Vollzylinder und das dornseitige Kraftumlenkelement als Hohlzylinder ausgebildet. Ein als Vollzylinder ausgebildeter Dorn kann in besonders einfacher Weise mit einem als Hohlzylinder ausgebildeten dornseitigen Kraftumlenkelement ausgestattet werden. Vorteilhafterweise ist der Innendurchmesser des dornseitigen Kraftumlenkelements nur wenig größer als der Außendurchmesser des Dorns. Das dornseitige Kraftumlenkelement kann dann bei Bedarf in einfacher Weise fest mit dem Dorn verbunden, bevorzugt verschweißt, werden. Preferably, the mandrel is designed as a solid cylinder and the mandrel-side force deflecting element as a hollow cylinder. A trained as a solid cylinder mandrel can be equipped in a particularly simple manner with a trained as a hollow cylinder mandrel-side Kraftumlenkelement. Advantageously, the inner diameter of the mandrel-side Kraftumlenkelements is only slightly larger than the outer diameter of the mandrel. The mandrel-side force deflecting element can then, if necessary, be firmly connected to the mandrel, preferably welded.
Gemäß einer weiteren Ausführungsform kann der Dorn aber auch als Vollquader ausgebildet sein. In diesem Fall wird der Dorn mit einem in Form von zwei Zylinderabschnitten ausgebildeten dornseitigen Kraftumlenkelement ausgestattet. Die Hülse ist in dieser Ausführungsform entsprechend als Hohlquader ausgebildet. Eine als Hohlquader ausgebildete Hülse, die einen als Vollquader ausgebildeten Dorn aufnimmt, erlaubt Relativbewegungen von Gebäudeteilen in nur einer Richtung. According to a further embodiment, however, the mandrel may also be formed as a full cuboid. In this case, the mandrel is equipped with a mandrel-side force deflection element designed in the form of two cylinder sections. The sleeve is designed accordingly in this embodiment as a hollow cuboid. A trained as a hollow cuboid sleeve that receives a formed as a full cuboid mandrel allows relative movements of building parts in only one direction.

Ausführungsformen, gemäß denen eine als Hohlzylinder ausgebildete Hülse einen als Vollzylinder ausgebildeten Dorn aufnimmt, erlauben Relativbewegungen von Gebäudeteilen in nur einer Richtung. Embodiments, according to which a sleeve designed as a hollow cylinder receives a mandrel formed as a solid cylinder, allow relative movements of building parts in only one direction.
Sollen Bewegungen in zwei Richtungen erlaubt sein, so wird der zylindrische Dorn von einer als Hohlquader ausgebildeten Hülse aufgenommen, wobei die Ausdehnung der Hülse in einer Richtung im Wesentlichen dem Durchmesser des Dorns entspricht. In diesem Fall kann der Dorn zum einen in Richtung seiner Längsachse in die Hülse eindringen, es sind aber auch horizontale Bewegungen des Dorns senkrecht zu seiner Längsachse möglich.

Um eine Einleitung der auftretenden Querkräfte in die Bauteile sicher zu stellen wird auch in diesem Fall die Hülse mit einem hülsenseitigen Kraftumlenkelement ausgestattet, welches dann von dem hülsenseitigen Verankerungsbügel bzw. den hülsenseitigen Verankerungsbügeln umschlungen wird. Um eine geeignete Kontaktfläche zu den Verankerungsbügeln zu erreichen, ist das hülsenseitige Kraftumlenkelement in diesem Fall in Form zweier Zylinderabschnitte ausgebildet. If movements in two directions are to be allowed, the cylindrical mandrel is received by a sleeve designed as a hollow cuboid, wherein the extension of the sleeve in one direction substantially corresponds to the diameter of the mandrel. In this case, the mandrel may penetrate into the sleeve in the direction of its longitudinal axis, but horizontal movements of the mandrel perpendicular to its longitudinal axis are also possible. In such a likewise preferred embodiment, the sleeve is formed as a hollow cuboid. In order to ensure an initiation of the transverse forces occurring in the components, the sleeve is equipped with a sleeve-side force deflecting element in this case, which is then looped around by the sleeve-side anchoring bracket or the sleeve-side anchoring brackets. To provide a suitable contact surface to the To achieve anchoring brackets, the sleeve-side force deflecting element is formed in this case in the form of two cylindrical sections.

Wege zur Ausführung der Erfindung Die Figuren 3A bis 3C verdeutlichen die Herstellung eines Verankerungsbügels gemäß der vorliegenden Erfindung durch zweifaches Biegen eines Baustahlstabes 30 (siehe Fig. 3A). Der Stahlstab wird zunächst einmal derart gebogen, dass die beiden Abschnitte des Stabes im Wesentlichen parallel zueinander verlaufen und die freien Enden des Stahlstabes bündig nebeneinander zu liegen kommen (siehe Fig. 3B). Den Enden des Stahlstabes gegenüberliegend entsteht dadurch ein schlaufenförmiger Bereich, für den ein Schlaufenabschnitt 10 definiert werden kann. Dieser geschlaufte, den Enden des Stahlstabes gegenüberliegende Bereich wird dann ein zweites Mal gebogen (siehe Fig. 1 C). Der zweifach gebogene Stahlstab stellt einen Verankerungsbügel 8 gemäß der vorliegenden Erfindung dar, wobei der Verankerungsbügel 8 in seinem Schlaufenabschnitt 10 fest mit einer Stirnplatte verbunden wird. Modes for Carrying Out the Invention Figs. 3A to 3C illustrate the manufacture of an anchoring bracket according to the present invention by bending a structural steel bar 30 twice (see Fig. 3A). The steel rod is first bent once so that the two sections of the rod are substantially parallel to each other and the free ends of the steel rod come to lie flush next to each other (see Fig. 3B). The ends of the steel rod opposite thereby creates a loop-shaped area, for which a loop portion 10 can be defined. This looped area opposite the ends of the steel bar is then bent a second time (see Fig. 1C). The double-curved steel bar represents an anchoring bracket 8 according to the present invention, wherein the Anchoring bracket 8 is firmly connected in its loop portion 10 with a front plate.
