Description

Gebiet der Erfindung.Field of the invention.

Die Erfindung betrifft eine Vorrichtung zur Querkraftverbindung gemäß Oberbegriff des Anspruchs 1.The invention relates to a device for transverse force connection according to the preamble of claim 1.

Bei dem ersten, beispielsweise plattenförmigen Bauteil aus bewehrtem Beton kann es sich insbesondere um einen Balkon, ein Podest oder einen Treppenlauf handeln und bei dem zweiten Bauteil um ein tragendes Bauteil wie eine Treppenhauswand. Es können mit solchen Vorrichtungen auch zwei plattenförmige Bauteile aus bewehrtem Beton, wie zwei Decken, miteinander verbunden werden, beispielsweise als Dehnfugenverbindung. Es kann sich auch um eine Verbindung zwischen einer Wand und einer Decke handeln.The first, for example, plate-shaped component made of reinforced concrete can be a balcony, a landing or a flight of stairs and the second component can be a load-bearing component such as a staircase wall. Such devices can also be used to connect two plate-shaped components made of reinforced concrete, such as two ceilings, to one another, for example as an expansion joint connection. It can also be a connection between a wall and a ceiling.

Die Erfindung betrifft des Weiteren ein Bauwerk mit einer solchen Vorrichtung und eine Verwendung einer solchen Vorrichtung.The invention further relates to a structure with such a device and a use of such a device.

Hintergrund der Erfindung und Stand der Technik.Background of the invention and state of the art.

Vorrichtungen zur Querkraftverbindung der eingangs genannten Art sind beispielsweise aus den Literaturstellen DE 197 39 446 A1 oder EP 3 023 555 B1 bekannt und werden insbesondere zur Auflagerung von beispielsweise plattenförmigen ersten Bauteilen, wie Podesten oder Treppenläufen, in tragenden zweiten Bauteilen wie einer Treppenhauswand eingesetzt. Die durch das Gewicht des ersten Bauteils bewirkte Querkraft wird dabei durch den in die Hülse mit einem Ende eingeschobenen Querkraftdorn in das zweite Bauteil übertragen. Bei dem Querkraftdorn handelt es sich beispielsweise um ein Vierkantrohr aus rostfreiem Stahl. Unter der Wirkung der Querkraft drückt der Querkraftdorn gegen die Oberseite der Hülse, welche den Druck an das Betonmaterial weitergibt. Dadurch bilden sich im Betonmaterial des ersten Bauteils Zugspannungen aus, welche durch die Bewehrung des ersten Bauteils aufgenommen werden müssen. Bis die Bewehrung diese Spannungen übernimmt, bilden sich Risse im Beton, meist ausgehend von der Hülse in deren randnahen Bereich. Sofern Feuchtigkeit durch diese Risse bis zur Bewehrung des plattenförmigen Bauteils eindringt, kommt es zu Korrosionsschäden an der Bewehrung. Die Risse werden im Rahmen der sogenannten Gebrauchstauglichkeit des ersten Bauelements deshalb nur toleriert, als ihre Weite ein gewisses Maß nicht übersteigt. Im Innenbereich von Gebäuden beträgt dieses Maß 0,4 mm und im Außenbereich 0,3 mm. Die Rissbildung ist umso ausgeprägter und kritischer, je dünner das erste Bauteil und damit die Betonschicht oberhalb der Hülse ist. Natürlich
spielt auch die Stärke der Bewehrung eine Rolle.
Devices for shear force connections of the type mentioned above are known, for example, from the literature DE 197 39 446 A1 or EP 3 023 555 B1 and are used in particular for supporting, for example, plate-shaped first components, such as landings or flights of stairs, in load-bearing second components such as a staircase wall. The shear force caused by the weight of the first component is transferred to the second component by the shear force mandrel, which is inserted into the sleeve at one end. The shear force mandrel is, for example, a square tube made of stainless steel. Under the effect of the shear force, the shear force mandrel presses against the top of the sleeve, which passes the pressure on to the concrete material. This creates tensile stresses in the concrete material of the first component, which must be absorbed by the reinforcement of the first component. Until the reinforcement takes over these stresses, cracks form in the concrete, usually starting from the sleeve near the edge. If moisture penetrates through these cracks to the reinforcement of the plate-shaped component, corrosion damage occurs to the reinforcement. The cracks are therefore only tolerated within the framework of the so-called serviceability of the first structural element if their width does not exceed a certain level. Inside buildings this value is 0.4 mm and outside it is 0.3 mm. The thinner the first component and thus the concrete layer above the sleeve, the more pronounced and critical the cracking is. Of course
the strength of the reinforcement also plays a role.

Dies bedeutet, dass eine möglichst weitgehende Verhinderung bzw. Minimierung einer Rissbildung essentiell für die lange statische Haltbarkeit des Bauwerkes aus Beton sind.This means that preventing or minimizing crack formation as much as possible is essential for the long static durability of the concrete structure.

Bei den bekannten Vorrichtungen nachteilig ist, dass bei der Montage praktisch keine Spielräume für leichte Verwinkelungen des Querkraftdornes bestehen, wie beispielsweise, wenn zumindest eines der zu verbindenden Bauteile leicht verzogen ist.A disadvantage of the known devices is that there is practically no room for slight bending of the shear force mandrel during assembly, for example if at least one of the components to be connected is slightly distorted.

Weitere Vorrichtungen zur Querkraftverbindung eines ersten Bauteils aus Beton mit einem zweiten Bauteil sind beispielsweise aus den Literaturstellen EP 2 754 766 B1 , EP 1 477620 B1 , EP 2 982 807 B1 , EP 3 339 525 B1 , EP 2 146 004 B1 , EP 2 516 761 B1 , DE 10 2005 036 8814 B4 , und EP 2 655 754 B1 bekannt.Further devices for the shear force connection of a first concrete component with a second component are known, for example, from the literature EP 2 754 766 B1 , EP1 477620 B1 , EP 2 982 807 B1 , EP 3 339 525 B1 , EP 2 146 004 B1 , EP 2 516 761 B1 , EN 10 2005 036 8814 B4 , and EP 2 655 754 B1 known.

Aus der Literaturstelle EP 0545854 A1 ist eine weitere Vorrichtung zur Querkraftverbindung bekannt, wobei eine äußere und eine innere Hülse vorgesehen sind, wobei die innere Hülse gegenüber der äußeren Hülse "schwimmend" dadurch gelagert ist, dass zwischen äußerer und innerer Hülse eine elastische Schicht zwecks Trittschalldämmung eingerichtet ist.From the literature reference EP0545854A1 A further device for transverse force connection is known, wherein an outer and an inner sleeve are provided, wherein the inner sleeve is mounted "floating" relative to the outer sleeve in that an elastic layer is installed between the outer and inner sleeve for the purpose of impact sound insulation.

Technisches Problem der Erfindung.Technical problem of the invention.

Der Erfindung liegt daher das technische Problem zu Grunde, eine Vorrichtung zur Querkraftverbindung eines ersten Bauteils aus Beton mit einem zweiten Bauteil aus Beton zu schaffen, welche eine einfachere Erstellung von Bauwerken aus zumindest zwei Bauteilen ermöglicht, insbesondere wenn zumindest eines der Bauteile einen gewissen Verzug aufweist.The invention is therefore based on the technical problem of creating a device for the transverse force connection of a first concrete component to a second concrete component, which enables a simpler construction of structures from at least two components, in particular if at least one of the components has a certain distortion.

Grundzüge der Erfindung und bevorzugte Ausführungsformen.Basic features of the invention and preferred embodiments.

Zur Lösung dieses technischen Problems lehrt die Erfindung den Gegenstand des Anspruchs 1.To solve this technical problem, the invention teaches the subject matter of claim 1.

Mit der Erfindung wird erreicht, dass das Bewehrungselement unabhängig von der Lage der Hülse ausgerichtet werden kann.The invention ensures that the reinforcement element can be aligned independently of the position of the sleeve.

Dies bedeutet, dass Hülse und Bewehrungselement frei gegeneinander verschwenkbar bzw. kippbar sind, und zwar ohne, dass Rückstellkräfte die Hülse in eine zum Bewehrungselement achsparallele oder koaxiale Lage zurückdrängen. Vorzugsweise ist der Raum zwischen Hülse und Bewehrungselement (bis zur Verfüllung mit Beton) leer (insbesondere nicht mit elastischen und/oder kompressiblen Feststoffen gefüllt), um eine Verschwenkbarkeit der Hülse im Bewehrungselement zu ermöglichen. Diese Ausrichtbarkeit bzw. Verschwenkbarkeit ist wichtig, denn in der Praxis kann es nämlich beispielsweise vorkommen, dass das erste Bauteil gleichsam etwas verzogen ist. Querkraftdorne werden dann gerne im Bereich eines solchen Verzugs oder einer solchen Schieflage eingebaut, da sie abhebende Kräfte aufnehmen und ein Kippen des ersten Bauteils verhindern sollen. Die Erfindung ermöglicht es dabei, das Bewehrungselement gegenüber der Hülse mehr oder weniger zu Verkippen, was die Montage ganz erheblich vereinfacht.This means that the sleeve and reinforcement element can be freely pivoted or tilted against each other without restoring forces pushing the sleeve back into a position that is parallel to the axis or coaxial with the reinforcement element. The space between the sleeve and reinforcement element (until it is filled with concrete) is preferably empty (in particular not filled with elastic and/or compressible solids) in order to enable the sleeve to pivot in the reinforcement element. This ability to align or pivot is important because in practice it can happen, for example, that the first component is slightly distorted. Shear force dowels are then often installed in the area of such a distortion or tilt because they absorb lifting forces and are intended to prevent the first component from tilting. The invention makes it possible to tilt the reinforcement element more or less relative to the sleeve, which makes assembly much easier.

Dies bedeutet auch, dass die Anforderungen an die Ausrichtung und Fixierung des Bewehrungselements im Rahmen der gesamten Bewehrung vor dem Betonieren geringer sind, und das "Feintuning" mit Hilfe der Ausrichtung der Hülse gegenüber dem Bewehrungselement erfolgen kann. Dies macht nicht nur das erhaltene Bauwerk nach dem Betonieren weniger anfällig gegen Risse, es wird auch eine Vereinfachung der Einrichtung der Bewehrung insgesamt vor dem Betonieren erreicht.This also means that the requirements for the alignment and fixation of the reinforcement element within the framework of the entire reinforcement before concreting are lower, and the "fine tuning" can be done by means of the alignment of the sleeve relative to the reinforcement element. This not only makes the resulting structure less susceptible to cracking after concreting, it also simplifies the overall setup of the reinforcement before concreting.

Das zweite Bauteil kann ein Betonbauteil sein, wobei der Querkraftdorn einbetoniert ist. Es ist aber auch möglich, dass das zweite Bauteil im Bereich des in das zweite Bauteil eingesetzten Querkraftdorns in Form einer Trittschalldämmbox ausgebildet ist, wobei diese Trittschalldämmbox einen Teil des zweiten Bauteils bildet. Typischerweise kann das zweite Bauteil außerhalb einer solchen Trittschalldämmbox aus einem beliebigen statisch geeigneten Material bestehen, meist wird es ebenfalls Beton, typischerweise aber nicht zwingend bewehrt, sein. Das zweite Bauteil kann beispielsweise eine Mauerwerkswand sein, bei welcher eine solche Trittschalldämmbox unter Einsatz einer Mörtelschicht ausgerichtet und eingebaut ist.The second component can be a concrete component, with the shear force dowel embedded in concrete. However, it is also possible that the second component in the area of the shear force dowel inserted into the second component is in the form of an impact sound insulation box is formed, whereby this impact sound insulation box forms part of the second component. Typically, the second component outside of such an impact sound insulation box can be made of any statically suitable material, usually it will also be concrete, but typically not necessarily reinforced. The second component can be, for example, a masonry wall in which such an impact sound insulation box is aligned and installed using a layer of mortar.

Generell ist es auch möglich, dass sowohl das erste als auch das zweite Bauteil jeweils ein Bewehrungselement mit eingeschobener Hülse aufweisen, wobei dann der Querkraftdorn mit seinen entgegengesetzten Enden in jeweils eine Hülse eingeschoben ist. Beispielsweise kann sich das bei zwei verbundenen plattenförmigen Bauteilen empfehlen. Dabei können beide Platten beider Bewehrungselemente mit erfindungsgemäß vergrößert ausgebildeter Ausnehmung versehen sein, es ist aber auch möglich, dass eine Ausnehmung einer Platte eine Querschnittsfläche aufweist, welche nahezu exakt der äußeren Querschnittsfläche der Hülse entspricht.In general, it is also possible for both the first and the second component to each have a reinforcement element with an inserted sleeve, with the shear force mandrel being inserted into a sleeve with its opposite ends. For example, this can be recommended for two connected plate-shaped components. Both plates of both reinforcement elements can be provided with an enlarged recess according to the invention, but it is also possible for a recess in a plate to have a cross-sectional area that corresponds almost exactly to the outer cross-sectional area of the sleeve.

Ein Bewehrungskorb kann grundsätzlich beliebig ausgebildet sein, sofern er eine längliche Form aufweist und von einer seiner Stirnseiten aus eine Hülse einschiebbar ist.In principle, a reinforcement cage can be designed in any way, provided it has an elongated shape and a sleeve can be inserted from one of its front sides.

Ein Bewehrungskorb kann beispielsweise zwei U-förmig gebogene Bewehrungsstäbe aufweisen, welche mit einem Abstand zueinander parallel angeordnet sind. Dabei ist dieser Abstand größer, insbesondere um zumindest 10%, 20%, 30%, 40%, oder 50% größer, aber auch um zumindest 60%, 70%, 80%, 90%, oder 100% größer, als der Außendurchmesser einer darin einführenden Hülse. Die jeweiligen Schenkel der U-förmigen Bewehrungsstäbe haben ebenfalls einen Abstand, welcher größer, insbesondere um zumindest 10%, 20%, 30%, 40%, oder 50% größer, aber auch um zumindest 60%, 70%, 80%, 90%, oder 100% größer, als der Außendurchmesser einer darin einführenden Hülse. Die beiden zueinander parallelen U-förmig gebogenen Bewehrungsstäbe können miteinander durch um die vier Schenkel der U-förmig gebogenen Bewehrungsstäbe umlaufende Ringstäbe verbunden sein. Die Ebene der Ringstäbe kann dabei orthogonal zu den vier Schenkeln der U-förmig gebogenen Bewehrungsstäbe stehen, es ist aber auch möglich, die Ringstäbe gegenüber der orthogonalen Stellung abzuwinkeln. Die Ringstäbe können über die Länge der Schenkel gleichmäßig oder ungleichmäßig verteilt sein. Es können 2 bis 20, insbesondere 2 bis 10, Ringstäbe für ein Paar U-förmig gebogene Bewehrungsstäbe vorgesehen sein.A reinforcement cage can, for example, have two U-shaped reinforcement bars which are arranged parallel to one another at a distance. This distance is larger, in particular by at least 10%, 20%, 30%, 40%, or 50% larger, but also by at least 60%, 70%, 80%, 90%, or 100% larger, than the outer diameter of a sleeve inserted into it. The respective legs of the U-shaped Reinforcing bars also have a spacing which is greater, in particular at least 10%, 20%, 30%, 40% or 50% greater, but also at least 60%, 70%, 80%, 90% or 100% greater, than the outer diameter of a sleeve inserted into it. The two U-shaped reinforcing bars which are parallel to one another can be connected to one another by ring bars which run around the four legs of the U-shaped reinforcing bars. The plane of the ring bars can be orthogonal to the four legs of the U-shaped reinforcing bars, but it is also possible to angle the ring bars relative to the orthogonal position. The ring bars can be evenly or unevenly distributed over the length of the legs. 2 to 20, in particular 2 to 10, ring bars can be provided for a pair of U-shaped reinforcing bars.

Ein Bewehrungselement wird aus dem länglichen Bewehrungskorb und einer an einer Stirnseite des Bewehrungskorbes angebrachten Platte gebildet. Die Platte ist dabei fest bzw. kraftübertragend mit dem Bewehrungskorb verbunden, stoffschlüssig (beispielsweise Verschweißen oder Verkleben) oder mittels Verbindungselementen, wie Schrauben, Nieten, oder Rastelelementen. Die Platte ist vorzugsweise eben und steht orthogonal zur Längserstreckung des Bewehrungskorbes. Es ist aber auch möglich, dass die ebene Platte gegenüber einer Längsachse des Bewehrungskorbes mit einem Winkel kleiner 90° und größer 45°, insbesondere größer 60°, 70°, oder 80°, abgewinkelt ist. Die Platte kann aber auch beispielsweise in Form eines Segmentes einer Zylindermantelfläche (Bogenform) gebogen sein, eine Abkantung aufweisen (Spitzdachform), oder eine Mehrzahl zueinander parallele Abkantungen aufweisen. Dies kann sich beispielsweise bei einem Bewehrungskorb mit U-förmig gebogenen Bewehrungsstäbe empfehlen, wobei dann eine Anpassung an die Form des "U" möglich ist.A reinforcement element is formed from the elongated reinforcement cage and a plate attached to one end of the reinforcement cage. The plate is firmly connected to the reinforcement cage or is connected in a force-transmitting manner, by means of a material bond (for example welding or gluing) or by means of connecting elements such as screws, rivets or locking elements. The plate is preferably flat and is orthogonal to the longitudinal extension of the reinforcement cage. However, it is also possible for the flat plate to be angled relative to a longitudinal axis of the reinforcement cage at an angle of less than 90° and greater than 45°, in particular greater than 60°, 70° or 80°. However, the plate can also be bent, for example, in the form of a segment of a cylinder surface (arch shape), have a bevel (pitched roof shape), or have a plurality of bevels parallel to one another. This can be the case, for example, with a reinforcement cage with a U-shaped We recommend using curved reinforcement bars, which can then be adapted to the shape of the "U".

Bevorzugt ist es, wenn die Ausnehmung der Platte eine Querschnittsfläche aufweist, welche um so viel größer als die äußere Querschnittsfläche der Hülse ist, dass die Hülse gegenüber der Platte um zumindest 2°, 3°, oder 4°, vorzugsweise zumindest 5°, 6°, 7°, 8°, 9° oder 10°, insbesondere von 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, oder 9° bis zu 10°, 15°, oder 30°, gemessen zwischen einer Längsachse des Bewehrungskorbes und einer Mittenachse der Hülse, verschwenkbar ist. Grundsätzlich ist auch möglich, dass die Ausnehmung der Platte in Kraftrichtung (beispielsweise nach unten) offen ist (bezogen auf die Lage der Platte im Bauwerk).It is preferred if the recess in the plate has a cross-sectional area that is so much larger than the outer cross-sectional area of the sleeve that the sleeve can be pivoted relative to the plate by at least 2°, 3°, or 4°, preferably at least 5°, 6°, 7°, 8°, 9° or 10°, in particular from 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, or 9° up to 10°, 15°, or 30°, measured between a longitudinal axis of the reinforcement cage and a center axis of the sleeve. In principle, it is also possible for the recess in the plate to be open in the direction of force (for example downwards) (relative to the position of the plate in the structure).

Die Querschnittsfläche der Ausnehmung der Platte und/oder die äußere Querschnittsfläche der Hülse können die Form eines Kreises, einer Ellipse, eines Quadrats oder eines Rechtecks aufweisen. Andere Formen sind selbstverständlich auch möglich. Hierbei ist es auch möglich, verschiedene Querschnittformen zu kombinieren und dabei vorzugsweise einen Punktkontakt zwischen Hülse und Platte zu vermeiden. Beispielsweise kann bei kreisförmiger äußerer Querschnittsfläche der Hülse die Querschnittfläche der Platte eine Ellipsenform aufweisen.The cross-sectional area of the recess in the plate and/or the outer cross-sectional area of the sleeve can have the shape of a circle, an ellipse, a square or a rectangle. Other shapes are of course also possible. It is also possible to combine different cross-sectional shapes and preferably avoid point contact between the sleeve and the plate. For example, if the outer cross-sectional area of the sleeve is circular, the cross-sectional area of the plate can have an elliptical shape.

Die Definition, wonach die Querschnittsfläche der Ausnehmung größer als die äußere Querschnittsfläche der Hülse ist, bezieht sich auf eine Projektion der Ausnehmung in Richtung der Längsachse des Bewehrungskorbes und impliziert, dass die Hülse durch die Platte schiebbar ist, ungeachtet der Form der Platte.The definition that the cross-sectional area of the recess is larger than the outer cross-sectional area of the sleeve refers to a projection of the recess in the direction of the longitudinal axis of the reinforcement cage and implies that the sleeve can be pushed through the plate regardless of the shape of the plate.

Die Hülse kann aus einem druckfesten Material, insbesondere einem Kunststoffmaterial oder einem metallischen Werkstoff, beispielsweise einem Eisen- oder Stahlwerkstoff, gebildet sein. Der Querkraftdorn kann aus einem scherfesten Material, insbesondere einem faserverstärkten Kunststoffmaterial oder einem metallischen Werkstoff, beispielsweise einem Stahlwerkstoff, gebildet sein.The sleeve can be made of a pressure-resistant material, in particular a plastic material or a metallic material, for example an iron or steel material. The transverse force mandrel can be made of a shear-resistant material, in particular a fiber-reinforced plastic material or a metallic material, for example a steel material.

Der Querkraftdorn kann im Wesentlichen spielfrei, insbesondere im Wesentlichen spielfrei in zumindest einer Richtung, aber auch in beiden Richtungen, orthogonal zur Längserstreckung von Hülse und Querkraftdorn, in die Hülse einschiebbar sein. Der Begriff "spielfrei" bedeutet dabei, dass sich der Querkraftdorn zwar ohne Klemmung in die Hülse einschieben lässt, jedoch eine Verkippung (vertikal und/oder horizontal) der Längsachsen von Querkraftdorn und Hülse gegeneinander bei in die Hülse eingeschobenem Querkraftdorn unter 5°, insbesondere unter 1°, liegt.The shear force mandrel can be inserted into the sleeve essentially without play, in particular essentially without play in at least one direction, but also in both directions, orthogonal to the longitudinal extension of the sleeve and shear force mandrel. The term "free of play" means that the shear force mandrel can be inserted into the sleeve without clamping, but that the tilting (vertical and/or horizontal) of the longitudinal axes of the shear force mandrel and sleeve against each other when the shear force mandrel is inserted into the sleeve is less than 5°, in particular less than 1°.

Die Hülse kann an einem Ende einen Abstandhalter, einen Kragen, oder einen Teilbereich aufweisen, deren äußere Querschnittfläche größer als die Querschnittsfläche der Ausnehmung der Platte ist. Ein solcher Abstandhalter ist beispielsweise dazu geeignet, ein Einhalten der Betondeckung zu gewährleisten. Dann lässt sich die Hülse nur so weit in das Bewehrungselement einschieben, bis der Abstandhalter, der Kragen, oder besagter Teilbereich an der Platte anschlägt. Das Ende der Hülse mit Abstandhalter, Kragen, oder besagtem Teilbereich ist zur randbündigen Einbettung in den Beton des ersten Bauteils bestimmt. Der Abstandshalter kann aber auch an einer Nagelplatte oder der Platte angeordnet und ggf. befestigt sein.The sleeve can have a spacer, a collar or a partial area at one end, the outer cross-sectional area of which is larger than the cross-sectional area of the recess in the plate. Such a spacer is suitable, for example, for ensuring that the concrete cover is maintained. The sleeve can then only be pushed into the reinforcement element until the spacer, the collar or the said partial area hits the plate. The end of the sleeve with the spacer, collar or the said partial area is intended for embedding flush with the edge in the concrete of the first component. The spacer can also be arranged on a nail plate or the plate and, if necessary, attached.

Die Ausnehmung der Platte oder der in der Ausnehmung der Platte zur Angabe kommende Bereich der Hülse kann eine innenseitig (bzw. außenseitig) zumindest teilweise umlaufende Polsterung aus einem, vorzugsweise druckelastischen, Werkstoff, insbesondere einem gummielastischen Werkstoff, aufweisen. Dadurch, dass die Ausnehmung in der Platte größer ist als der Außenquerschnitt der Hülse (Neigbarkeit), ist es vorteilhaft, wenn die Hülse zur Lasteinleitung an der Platte anliegt. Diese Lagesicherung muss nicht zwingend mit einem druckelastischen Werkstoff ausgeführt werden. Möglich wäre beispielsweise auch ein Federstahlelement, ein entsprechendes Teil aus hartem Kunststoff oder ein Gummiband, das über die Platte geführt wird und beidseitig die Hülse umschließt.The recess in the plate or the area of the sleeve that is defined in the recess in the plate can have at least partially surrounding padding on the inside (or outside) made of a material that is preferably elastic under pressure, in particular a rubber-elastic material. Because the recess in the plate is larger than the outside cross-section of the sleeve (inclination), it is advantageous if the sleeve rests against the plate to introduce the load. This positional securing does not necessarily have to be carried out using a material that is elastic under pressure. Other options would be a spring steel element, a corresponding part made of hard plastic or a rubber band that is guided over the plate and encloses the sleeve on both sides.

Die Erfindung betrifft des Weiteren ein Bauwerk nach Anspruch 8. Dabei werden der Querkraftdorn und der Bewehrungskorb typischerweise, aber nicht zwingend, mit ihren Längsachsen horizontal orientiert sein. Generell ist es möglich, dass sowohl das erste als auch das zweite Bauteil jeweils ein Bewehrungselement mit eingeschobener Hülse aufweisen, wobei dann der Querkraftdorn mit seinen entgegengesetzten Enden in jeweils eine Hülse eingeschoben ist. Beispielsweise kann sich das bei zwei verbundenen plattenförmigen Bauteilen empfehlen.The invention further relates to a structure according to claim 8. The shear force dowel and the reinforcement cage are typically, but not necessarily, oriented horizontally with their longitudinal axes. In general, it is possible for both the first and the second component to each have a reinforcement element with an inserted sleeve, with the shear force dowel then being inserted into a sleeve with its opposite ends. This can be recommended, for example, for two connected plate-shaped components.

Weiterhin betrifft die Erfindung eine Verwendung nach Anspruch 9. Im Rahmen der Verwendung wird typischerweise das Bewehrungselement im Rahmen einer Gesamtbewehrung eines ersten Bauteils in dieser fixiert, wird dann die Hülse in das Bewehrungselement eingeführt, ausgerichtet und ebenfalls fixiert, und wird schließlich die Gesamtbewehrung, einschließlich Bewehrungskorb und Hülse, einbetoniert, wodurch eine Verkippung zwischen Bewehrungskorb und Hülse im Rahmen der Ausrichtung letztendlich starr durch die Hülse umschließenden und ausgehärteten Beton fixiert ist.Furthermore, the invention relates to a use according to claim 9. In the context of the use, the reinforcement element is typically fixed in the context of an overall reinforcement of a first component, then the sleeve is inserted into the reinforcement element, aligned and also fixed, and finally the entire reinforcement, including the reinforcement cage and sleeve, is cast in concrete, whereby any tilting between the reinforcement cage and the sleeve during alignment is ultimately rigidly fixed by the hardened concrete surrounding the sleeve.

Alle für die Gegenstände der Ansprüche 1 bis 7 angebrachten Erläuterungen und beschriebenen Ausführungsformen gelten analog für die Gegenstände der Ansprüche 8 und 9.All explanations and described embodiments for the subject matter of claims 1 to 7 apply analogously to the subject matter of claims 8 and 9.

Im Folgenden wird die Erfindung anhand von lediglich ein Ausführungsbeispiel darstellenden Figuren näher erläutert. Es zeigen:

Fig. 2:
Eine Ausführungsform einer erfindungsgemäßen Vorrichtung,
The invention is explained in more detail below using figures that represent only one embodiment. They show:
Fig.1
A schematic view of a structure in a vertical cross-section (comparative example),
Fig. 2:
An embodiment of a device according to the invention,

In der Figur 1 erkennt man ein erstes Bauteil 1 aus bewehrtem Beton und ein zweites Bauteil 2, welche miteinander verbunden sind. Zum Zwecke der Verbindung sind eine länglich ausgebildeten Hülse 3 und ein Querkraftdorn 4 eingerichtet. Die Hülse 3 ist randbündig in den Beton des ersten Bauteils 1 eingebettet. Der Querkraftdorn 4 ist von außen in die Hülse 3 eingeschoben,
Einer vergleichenden Betrachtung der Figuren 1 und 2 entnimmt man, die Hülse 3 in ein Bewehrungselement 5 eingesetzt bzw. einsetzbar ist. Das Bewehrungselement 5 ist mit einem länglichen Bewehrungskorb 6 und einer an einer Stirnseite 7 des Bewehrungskorbes 6 angeordneten Platte 9 ausgebildet. Die Platte 9 ist mit dem Bewehrungskorb 6 fest verbundenen. Die Platte 9 ist eben und steht im Wesentlichen orthogonal zur Längserstreckung der Hülse 3.
In the Figure 1 one can see a first component 1 made of reinforced concrete and a second component 2, which are connected to each other. For the purpose of the connection, an elongated sleeve 3 and a shear force mandrel 4 are set up. The sleeve 3 is embedded flush with the edge in the concrete of the first component 1. The shear force mandrel 4 is inserted into the sleeve 3 from the outside,
A comparative analysis of the Figures 1 and 2 can be seen that the sleeve 3 is inserted or can be inserted into a reinforcement element 5. The reinforcement element 5 is provided with an elongated reinforcement cage 6 and a Front side 7 of the reinforcement cage 6 is formed by a plate 9 arranged. The plate 9 is firmly connected to the reinforcement cage 6. The plate 9 is flat and is essentially orthogonal to the longitudinal extension of the sleeve 3.

Die Platte 9 weist eine Ausnehmung 10 auf, durch welche die Hülse 3 hindurchsteckbar ist mit der Maßgabe, dass der hindurchgesteckte Teil der Hülse 3 im Inneren des Bewehrungskorbes 6 platziert ist.The plate 9 has a recess 10 through which the sleeve 3 can be inserted, provided that the inserted part of the sleeve 3 is placed inside the reinforcement cage 6.

Insbesondere der Figur 2 ist entnehmbar, dass Ausnehmung 10 der Platte 9 eine Querschnittsfläche aufweist, welche um so viel größer als die äußere Querschnittsfläche der Hülse 3 ist, dass die Hülse 3 gegenüber dem Bewehrungskorb 6 um zumindest 1°, gemessen zwischen zumindest einer Längsachse 11 des Bewehrungskorbes 6 und einer Mittenachse 12 der Hülse 3, verschwenkbar ist. In der Figur 1 sind demgegenüber (mit derselben Ausnehmung 11) besagte Achsen koaxial zueinander.In particular, the Figure 2 it can be seen that recess 10 of plate 9 has a cross-sectional area which is so much larger than the outer cross-sectional area of sleeve 3 that sleeve 3 can be pivoted relative to reinforcement cage 6 by at least 1°, measured between at least one longitudinal axis 11 of reinforcement cage 6 and a center axis 12 of sleeve 3. In the Figure 1 In contrast (with the same recess 11) said axes are coaxial to each other.

Im konkret gezeichneten Ausführungsbeispiel haben die Querschnittsfläche der Ausnehmung 10 der Platte 9 und die äußere Querschnittsfläche der Hülse 3 die Form eines Kreises.In the specific embodiment shown, the cross-sectional area of the recess 10 of the plate 9 and the outer cross-sectional area of the sleeve 3 have the shape of a circle.

Im Ausführungsbeispiel bestehen die Hülse 3 und der Querkraftdorn 4 aus Edelstahl.In the exemplary embodiment, the sleeve 3 and the shear force mandrel 4 are made of stainless steel.

In der Figur 1 sind Querkraftdorn 4 und Hülse 3 mit deutlich unterschiedlichem außen- bzw. Innendurchmesser gezeichnet, was der Übersichtlichkeit der Zeichnung geschuldet ist. In der Praxis ist der Querkraftdorn 4 im Wesentlichen spielfrei, insbesondere im Wesentlichen spielfrei in zumindest einer Richtung orthogonal zur Längserstreckung von Hülse 3 und Querkraftdorn 4, beispielsweise vertikal, in die Hülse einschiebbar.In the Figure 1 The shear force mandrel 4 and the sleeve 3 are shown with significantly different outer and inner diameters, which is due to the clarity of the drawing. In practice, the shear force mandrel 4 is essentially free of play, in particular essentially free of play in at least one direction orthogonal to the longitudinal extension of Sleeve 3 and shear mandrel 4 can be inserted into the sleeve, for example vertically.

Die Hülse 3 weist in diesem Ausführungsbeispiel, aber nicht zwingend, an einem Ende einen Teilbereich 13 auf, dessen äußere Querschnittfläche größer als die Querschnittsfläche der Ausnehmung 10 der Platte 9 ist.In this embodiment, but not necessarily, the sleeve 3 has at one end a partial region 13 whose outer cross-sectional area is larger than the cross-sectional area of the recess 10 of the plate 9.

Der Figur 2 ist entnehmbar, dass die Ausnehmung 10 der Platte 9 in diesem Ausführungsbeispiel eine innenseitig zumindest teilweise umlaufende Polsterung 14 aus einem elastischen Werkstoff, insbesondere einem gummielastischen Werkstoff, aufweist.The Figure 2 It can be seen that the recess 10 of the plate 9 in this embodiment has an inner side at least partially circumferential padding 14 made of an elastic material, in particular a rubber-elastic material.

Wiederum in der Figur 1 erkennt man, dass der Querkraftdorn 4 in einer Trittschalldämmbox 15 gelagert ist, welche wiederum im zweiten Bauteil 2 eingebaut bzw. einbetoniert ist.Again in the Figure 1 one can see that the shear force mandrel 4 is mounted in an impact sound insulation box 15, which in turn is installed or concreted into the second component 2.
