Description

Technisches GebietTechnical area

Die vorliegende Erfindung betrifft ein Bauelement zum Verbinden von zwei durch eine Fuge getrennten Gebäudeteilen.The present invention relates to a component for connecting two parts of a building separated by a joint.

Stand der TechnikState of the art

Bauelemente zum Verbinden von zwei durch eine Fuge getrennten Gebäudeteilen werden verwendet, um eine kraftaufnehmende Verbindung zwischen den Gebäudeteilen zu schaffen, die zudem eine Dämmung, insbesondere Schalldämmung der Gebäudeteile gegeneinander gewährleistet. Derartige Bauelemente werden z.B. für die Verbindung eines Treppenpodests mit einem Treppenkörper verwendet. Eine besondere Rolle spielt hier die Trittschalldämmung.Components for connecting two separated by a joint building parts are used to create a force-absorbing connection between the building parts, which also ensures insulation, in particular sound insulation of the building parts against each other. Such devices are e.g. used for connecting a landing with a staircase body. A special role here plays the impact sound insulation.

Aus der DE 44 09 477 A1 ist ein trittschalldämmendes Auflagerelement zur Verbindung zweier Bauteile bekannt. Das Auflagerelement weist einen einem der Bauteile zugeordneten Querkraftdorn und eine dem anderen Bauteil zugeordnete Aufnahme für den Querkraftdorn auf. Der Querkraftdorn kann zur Herstellung einer Vertikalkräfte übertragenden Wirkverbindung in die Aufnahme eingebracht werden.From the DE 44 09 477 A1 is a footfall sound absorbing support member for connecting two components known. The support element has a transverse force mandrel associated with one of the components and a receptacle for the transverse force mandrel assigned to the other component. The transverse force mandrel can be introduced into the receptacle for producing a vertical connection transmitting active force.

Ein ähnliches Querkraftlager ist aus der DE 197 39 446 A1 bekannt. Neben Dorn und Hülse weist das Querkraftlager zwei massive Kopfplatten auf, die beidseits einer Dehnfuge angeordnet werden. Die Kopfplatten sind mit der in das jeweilige Bauteil hineinragenden Bewehrung verbunden und dienen dadurch als Drucklager für die direkte Abstützung des Betons.A similar lateral force bearing is from the DE 197 39 446 A1 known. In addition to the mandrel and sleeve, the transverse force bearing has two massive head plates, which are arranged on both sides of an expansion joint. The top plates are connected to the projecting into the respective component reinforcement and thereby serve as a thrust bearing for the direct support of the concrete.

Die EP 2 481 867 A1 zeigt ein Bauelement, welches im Bereich einer Trennfuge zwischen einem Treppenpodest und einem Treppenkörper angeordnet ist. Das Bauelement enthält ein eine Trennplatte durchsetzendes trogförmiges Schalteil, welches im Verlauf der Herstellung der Gebäudeteile mit Beton vergossen wird, wodurch ein Kraftübertragungselement gebildet wird.The EP 2 481 867 A1 shows a component which is arranged in the region of a parting line between a landing and a staircase body. The component includes a partition plate passing through a trough-shaped shell part, which is cast during the manufacture of the building parts with concrete, whereby a force transmission element is formed.

Die EP 2 626 479 A2 zeigt ebenfalls ein Bauelement zum Einbau in der Trennfuge zwischen einem Treppenpodest und einem Treppenkörper, bei welchem ein Bewehrungselement durch eine in der Trennfuge angeordnete Trennplatte ragt und an seinem in den Treppenkörper ragenden Ende ein Tragelement aufweist, welches nach dem Vergießen mit Beton zur Verankerung in dem Treppenkörper dient.The EP 2 626 479 A2 also shows a component for installation in the parting line between a stair landing and a staircase, in which a reinforcing element protrudes through an arranged in the parting line partition plate and at its projecting into the staircase end has a support member which after casting with concrete for anchoring in the Stair body serves.

Trotz dieser aus dem Stand der Technik bekannten Lösungen besteht ein Bedarf an statisch gut belastbaren und gut dämmenden Bauelementen für die schalldämmende Verbindung von Gebäudeteilen.Despite these known from the prior art solutions, there is a need for static well-loadable and well-insulating components for the soundproofing of building parts.

Darstellung der ErfindungPresentation of the invention

Es ist Aufgabe der Erfindung, ein Bauelement zum Verbinden von zwei durch eine Fuge getrennten Gebäudeteilen zu schaffen, insbesondere ein Bauelement zum Verbinden eines Treppenpodest mit einem Treppenkörper, welches eine gute Kraftübertragung und eine gute Schalldämmung gewährleistet.It is an object of the invention to provide a device for connecting two separated by a joint building parts, in particular a device for connecting a stair landing with a staircase, which ensures good power transmission and good sound insulation.

Diese Aufgabe wird erfindungsgemäß durch ein Bauelement mit den Merkmalen des Patentanspruchs 1 gelöst. Weitere vorteilhafte Aspekte, Details und Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen, der Beschreibung sowie den Zeichnungen.This object is achieved by a device having the features of claim 1. Further advantageous aspects, details and embodiments of the invention will become apparent from the dependent claims, the description and the drawings.

Das erfindungsgemäße Bauelement zur schalldämmenden, kraftübertragenden Verbindung eines ersten Gebäudeteils mit einem von dem ersten Gebäudeteil durch eine Fuge getrennten zweiten Gebäudeteil, insbesondere zur schalldämmenden, kraftübertragenden Verbindung einer Treppe mit einem Treppenpodest, umfasst eine im eingebauten Zustand in der Fuge angeordnete Trennplatte, wenigstens ein sich im eingebauten Zustand des Bauelements in das erste Gebäudeteil erstreckendes Bewehrungselement und wenigstens ein fest mit dem Bewehrungselement verbundenes Kraftübertragungselement. Das Kraftübertragungselement ist L-Profil-artig ausgebildet. Das L-Profil weist einen flächig ausgebildeten Flansch und einen flächig ausgebildeten Steg auf. Der Flansch ist im eingebauten Zustand an der dem ersten Gebäudeteil zugewandten Seite der Trennplatte angeordnet, erstreckt sich im Wesentlichen parallel zur Trennplatte und liegt flächig an der Trennplatte an. Der Steg schließt mit dem Flansch einen Winkel zwischen 45° und 135° ein und durchdringt die Trennplatte. Er erstreckt sich im eingebauten Zustand in den zweiten Gebäudeteil, vorzugsweise in einen Treppenkörper. Steg und Flansch des L-Profil-artig ausgebildeten Kraftübertragungselements stellen die Kraftübertragung zwischen den Gebäudeteilen sicher.The component according to the invention for sound-absorbing, force-transmitting connection of a first building part with a second building part separated from the first building part by a joint, in particular for sound-absorbing, force-transmitting connection of a staircase with a stair landing a arranged in the installed state in the joint partition plate, at least one in the installed state of the device in the first part of the building extending reinforcing element and at least one fixedly connected to the reinforcing element force transmission element. The power transmission element is designed L-profile-like. The L-profile has a flat flange and a flat web. The flange is arranged in the installed state on the side facing the first part of the building part of the partition plate, extending substantially parallel to the partition plate and lies flat against the partition plate. The web forms an angle between 45 ° and 135 ° with the flange and penetrates the separating plate. It extends in the installed state in the second part of the building, preferably in a staircase. Web and flange of the L-profile-like trained power transmission element ensure the power transmission between the building parts.

Das Kraftübertragungselement ist somit sehr gut in der Lage, die zwischen dem ersten und zweiten Gebäudeteil auftretenden Kräfte, insbesondere Querkräfte, zu übertragen. Durch das Zusammenwirken mit der Trennplatte wird dabei eine gute Schalldämmung erzielt.The force transmission element is thus very well able to transmit the forces occurring between the first and second building part, in particular lateral forces. The interaction with the partition plate while a good soundproofing is achieved.

Da der Flansch des Kraftübertragungselementes flächig an der Trennplatte anliegt, schließt er in etwa mit der Oberfläche des zu betonierenden ersten Gebäudeteils, insbesondere Treppenpodestes, ab, was zu einer optimalen Abstützung des Kraftübertragungselementes an dem ersten Gebäudeteil führt.Since the flange of the power transmission element rests flat against the partition plate, it closes off approximately with the surface of the concrete to be concreted first part of the building, in particular Treppenpodestes, which leads to an optimal support of the power transmission element to the first part of the building.

Steg und Flansch des Kraftübertragungselements sind beide flächig ausgebildet, können ansonsten aber eine beliebige Form aufweisen. So können Steg und Flansch in einer Parallelprojektion ihrer jeweiligen Hauptflächen eine rechteckige, quadratische, ovale, kreisrunde oder beliebige andere Form aufweisen. Bevorzugt sind Steg und Flansch in ihrer Parallelprojektion rechteckig ausgebildet. In einem im eingebauten Zustand vertikalen Schnitt senkrecht durch die zwischen den beiden Gebäudeteilen verlaufende Fuge sind Steg und Flansch des Kraftübertragungselements mit im Wesentlichen ebenen Oberflächen ausgestattet. In der genannten Schnittansicht können Steg und Flansch eine quadratische, rechteckige, trapezförmige Gestalt aufweisen oder beispielsweise auch die Form eines Parallelogramms aufweisen. Insbesondere der Steg kann in der genannten Schnittansicht auch keilförmig, keilstumpfförmig oder an seinem dem Flansch abgewandten Ende sich verjüngend ausgebildet sein.Web and flange of the power transmission element are both formed flat, but otherwise may have any shape. Thus, the web and flange can have a rectangular, square, oval, circular or any other shape in a parallel projection of their respective major surfaces. Preferably, web and flange are rectangular in their parallel projection. In a vertically vertical cut in the installed state through the gap extending between the two building parts, the web and the flange of the force transmission element are provided with substantially planar surfaces. In the aforementioned sectional view, web and flange can have a square, rectangular, trapezoidal shape or, for example, also the shape of a parallelogram exhibit. In particular, the web can also be wedge-shaped, wedge-shaped or tapered at its end facing away from the flange in said sectional view.

Unter dem Winkel, den der Steg des Kraftübertragungselements mit dem Flansch des Kraftübertragungselements einschließt, ist im Rahmen der vorliegenden Anmeldung der Winkel zwischen den beiden Schwerpunktsebenen von Steg und Flansch zu verstehen. Der Begriff "Schwerpunktsebene" ist dem Fachmann geläufig. Die Schwerpunktsebene des Stegs oder des Flansches des Kraftübertragungselements ist eine Ebene, die Steg bzw. Flansch des Kraftübertragungselements in zwei Hälften mit gleicher Masse unterteilt, wobei die Schwerpunktsebene die beiden Oberflächen mit größter Ausdehnung von Steg bzw. Flansch nicht schneidet. Im Falle eines quaderförmigen Abschnitts verläuft die Schwerpunktsebene parallel zu den beiden Oberflächen mit größter Ausdehnung von Steg bzw. Flansch und ist von diesen beiden Ebenen gleich weit beabstandet.At the angle which the web of the force transmission element encloses with the flange of the force transmission element, in the context of the present application the angle between the two center of gravity planes of web and flange is to be understood. The term "center of gravity" is familiar to the person skilled in the art. The center of gravity of the web or the flange of the power transmission element is a plane which divides web or flange of the force transmission element into two halves of equal mass, the center of gravity plane does not intersect the two surfaces with the greatest extent of web or flange. In the case of a cuboid section, the center of gravity plane runs parallel to the two surfaces with the greatest extent of web or flange and is equidistant from these two planes.

Vorzugsweise ist das im eingebauten Zustand des Bauelements sich in das erste Gebäudeteil erstreckende Bewehrungselement im eingebauten Zustand vollständig von dem ersten Gebäudeteil umschlossen.Preferably, in the installed state of the component is in the first part of the building extending reinforcing element in the installed state completely enclosed by the first part of the building.

Vorzugsweise erstreckt sich die Trennplatte zwischen den beiden Gebäudeteilen im eingebauten Zustand vertikal, entsprechend dem üblichen Fugenverlauf zwischen Gebäudeteilen. Das Bauelement kann in entsprechender Orientierung jedoch auch für horizontal verlaufende oder geneigte Fugen verwendet werden.Preferably, the partition plate between the two parts of the building in the installed state extends vertically, according to the usual joint profile between building parts. The component can be used in a corresponding orientation, however, also for horizontally extending or inclined joints.

In einer vorteilhaften Ausführungsform der Erfindung schließt der Steg mit dem Flansch einen Winkel zwischen 75° und 105°, bevorzugt einen Winkel zwischen 85° und 95°, besonders bevorzugt einen Winkel von rund 90° ein, was dazu führt, dass sich der Steg im Wesentlichen quer zur Trennfuge, d.h. üblicherweise horizontal in den zweiten Gebäudeteil, z.B. den Treppenkörper, erstreckt. Eine derartige horizontale Anordnung kann die bei Belastung des zweiten Gebäudeteils auftretenden Querkräfte am effektivsten aufnehmen.In an advantageous embodiment of the invention, the web closes with the flange an angle between 75 ° and 105 °, preferably an angle between 85 ° and 95 °, more preferably an angle of about 90 °, which causes the web in the Substantially transversely to the parting line, ie usually horizontally in the second part of the building, for example, the staircase extends. Such a horizontal arrangement can absorb the lateral forces occurring under load of the second building part most effectively.

Vorzugsweise ist die Trennplatte mehrschichtig aufgebaut, wobei zumindest eine Schicht aus einem Dämmmaterial besteht. Eine derartige Trennplatte ist sehr gut in der Lage, eine Schalldämmung zwischen dem ersten und dem zweiten Gebäudeteil zu schaffen. Vorzugsweise ist die Trennplatte als Verbundplatte aufgebaut, die eine mittlere weiche Dämmschicht aufweist, die beidseitig von einer festen Platte aus beispielsweise Kunststoff oder Mineralwolle, bevorzugt Hartkunststoff, umgeben ist. Eine derartige Trennplatte hat sowohl eine gute Schalldämmung und ist andererseits aufgrund der Konstruktion gut in der Lage, Kräfte aufzunehmen. Sie kann auf der Baustelle einfach gehandhabt werden und ist unempfindlich gegen Beschädigung.Preferably, the partition plate is constructed in multiple layers, wherein at least one layer consists of an insulating material. Such a partition plate is very well able to provide a sound insulation between the first and the second part of the building. Preferably, the partition plate is constructed as a composite plate having a middle soft insulating layer, which is on both sides of a solid plate, for example, plastic or mineral wool, preferably hard plastic, surrounded. Such a partition plate has both a good sound insulation and on the other hand, due to the construction well able to absorb forces. It can be easily handled on the construction site and is insensitive to damage.

Vorzugsweise ist der sich in das zweite Gebäudeteil erstreckende Steg des Kraftübertragungselementes zumindest teilweise, vorzugsweise im Bereich seiner kraftübertragenden Fläche, mit einer Elastomerschicht versehen, insbesondere überdeckt. Auf diese Weise wird auch bei den kraftübertragenden Flächen des Kraftübertragungselements eine optimale Schalldämmung realisiert.Preferably, the extending into the second part of the building web of the power transmission element is at least partially, preferably provided in the region of its force-transmitting surface, with an elastomer layer, in particular covered. In this way, an optimal sound insulation is realized even in the force-transmitting surfaces of the power transmission element.

Das Kraftübertragungselement ist vorzugsweise als massives Stahlteil ausgebildet, um große Kräfte übertragen zu können. Da Stahl ein sehr guter akustischer Leiter ist, ist es vorteilhaft, wenn sich der in den zweiten Gebäudeteil erstreckende Steg des Kraftübertragungselements zumindest teilweise mit Dämmmaterial ummantelt ist. Auf diese Weise wird die Schaffung von Schallbrücken zwischen den Gebäudeteilen vermieden und somit eine gute akustische Entkopplung der beiden Gebäudeteile beidseitig der Trennfuge realisiert.The power transmission element is preferably designed as a solid steel part in order to transmit large forces. Since steel is a very good acoustic conductor, it is advantageous if the web of the force transmission element extending into the second building part is at least partially encased with insulating material. In this way, the creation of sound bridges between the building parts is avoided and thus realized a good acoustic decoupling of the two parts of the building on both sides of the parting line.

In einer vorteilhaften Weiterbildung der Erfindung deckt die Elastomerschicht im eingebauten Zustand des Elementes die Oberseite des Stegs des Kraftübertragungselements ab und das Dämmmaterial ummantelt die Unterseite und die Seitenflächen des Stegs des Kraftübertragungselements. Auf diese Weise wird eine optimale Schalldämmung an der kraftübertragenden Fläche des Kraftübertragungselement realisiert.In an advantageous embodiment of the invention, the elastomer layer covers in the installed state of the element from the top of the web of the power transmission element and the insulating material encases the bottom and the side surfaces of the web of the power transmission element. In this way, an optimal sound insulation is realized on the force-transmitting surface of the power transmission element.

Vorzugsweise ist der Flansch an seiner der Trennplatte abgewandten Seite fest mit dem sich in das erste Gebäudeteil ersteckende Bewehrungselement verbunden, insbesondere verschweißt. Auf diese Weise wird der Flansch des Kraftübertragungselements sicher in dem ersten Gebäudeteil verankert und gewährleistet somit eine sichere Kraftübertragung zwischen dem ersten und zweiten Gebäudeteil.Preferably, the flange is fixedly connected at its side facing away from the partition plate with the reinforcing element which extends into the first building part, in particular welded. In this way, the flange of the power transmission element is securely anchored in the first part of the building and thus ensures a safe power transmission between the first and second part of the building.

In einer vorteilhaften Ausführungsform der Erfindung weist das Bewehrungselement einen parallel zur Trennwand verlaufenden, also im eingebauten Zustand vorzugsweise horizontal orientierten Bewehrungsstab auf. Ein derartiger Bewehrungsstab kann mehrere nebeneinander angeordnete Kraftübertragungselemente miteinander verbinden, so dass hierdurch ein Bauelement mit mehreren Kraftübertragungselementen einfacher zu handhaben ist.In an advantageous embodiment of the invention, the reinforcing element has a parallel to the partition wall extending, so preferably in the installed state horizontally oriented reinforcing rod. Such a reinforcing rod can connect a plurality of juxtaposed force transmission elements together, so that in this way a device with multiple power transmission elements is easier to handle.

In einer weiteren vorteilhaften Ausführungsform der Erfindung weist das Bewehrungselement wenigstens einen sich in einer Richtung von der Trennplatte weg in das erste Gebäudeteil erstreckenden Bewehrungsstab auf. Ein derartiger Bewehrungsstab dient zu einer stabilen Verankerung des Kraftübertragungselements in dem ersten Gebäudeteil. Besonders bevorzugt sind pro Kraftübertragungselement zwei, sich in den ersten Gebäudeteil erstreckende Bewehrungsstäbe vorgesehen. Beide Bewehrungsstäbe sind beabstandet zueinander fest mit dem Flansch des jeweiligen Kraftübertragungselementes verbunden.In a further advantageous embodiment of the invention, the reinforcing element has at least one reinforcing bar extending in a direction away from the separating plate into the first building part. Such a reinforcing rod is used for a stable anchoring of the power transmission element in the first part of the building. Particularly preferred per force transmission element two, provided in the first part of the building reinforcing bars are provided. Both reinforcing rods are spaced from each other firmly connected to the flange of the respective power transmission element.

In einer vorteilhaften Weiterbildung der Erfindung weist das Bewehrungselement wenigstens einen kreisförmig oder spiralförmig verlaufenden Bewehrungsabschnitt auf. Unter dem Begriff "kreisförmig" sind dabei auch Teile eines Kreises zu verstehen wie beispielsweise ein Halbkreis oder ein Dreiviertelkreis. Im Falle eines spiralförmigen Bewehrungsabschnitts verläuft die Achse der Spirale im eingebauten Zustand bevorzugt horizontal. Dabei muss die Spirale keinen vollständigen, 360° umfassenden Abschnitt bilden. Vielmehr kann es sich auch um eine Spirale handeln, die beispielsweise lediglich 180° oder 270° umläuft und damit in der Projektion in Richtung der Spiralachse einen Halbkreis oder einen Dreiviertelkreis bildet. Der kreisförmig oder spiralförmig verlaufende Bewehrungsabschnitt wird vorzugsweise an einem Bereich seines Umfangs mit dem Flansch des Kraftübertragungselements verschweißt. Ein derartiger Bewehrungsabschnitt stellt eine stabile Verankerung des Kraftübertragungselements in dem ersten Gebäudeteil sicher. Aus Korrosionsgründen bestehen das Bewehrungselement und das Kraftübertragungselement bevorzugt aus nichtrostendem Stahl.In an advantageous development of the invention, the reinforcing element has at least one circular or spiral reinforcing section. The term "circular" also includes parts of a circle, such as a semicircle or a three-quarter circle. In the case of a spiral reinforcement section, the axis of the spiral preferably runs horizontally when installed. The spiral does not have to form a complete 360 ° section. Rather, it may also be a spiral which, for example, rotates only 180 ° or 270 ° and thus forms a semicircle or a three-quarter circle in the projection in the direction of the spiral axis. The circular or spiral reinforcing section is preferably welded to the flange of the power transmission element at a portion of its circumference. Such a reinforcement section ensures a stable anchoring of the force transmission element in the first part of the building. For corrosion reasons The reinforcing element and the force transmission element are preferably made of stainless steel.

Vorzugsweise enthält das Bauelement eine Trennplatte und mehrere im eingebauten Zustand insbesondere horizontal nebeneinander angeordnete Kraftübertragungselemente. Um eine optimale Kraftübertragung zu gewährleisten, sollten die Kraftübertragungselemente in einem vorgegebenen Abstand angeordnet sein, der entsprechend der zwischen den Gebäudeteilen zu übertragenden Kraft zu wählen ist. Durch das Vorsehen mehrerer nebeneinander angeordneter Kraftübertragungselemente kann somit die Kraftübertragung entsprechend der Größe des Verbindungsbereichs zwischen dem ersten und zweiten Gebäudeteil eingestellt werden.Preferably, the component includes a partition plate and a plurality of power transmission elements arranged in the installed state, in particular horizontally next to one another. In order to ensure optimum power transmission, the power transmission elements should be arranged at a predetermined distance, which is to be selected according to the force to be transmitted between the building parts. By providing a plurality of juxtaposed force transmission elements thus the power transmission can be adjusted according to the size of the connecting region between the first and second building part.

Vorzugsweise ist das Kraftübertragungselement als massives Stahlteil ausgebildet, was dazu führt, dass zum einen große Kräfte zwischen dem ersten und zweiten Gebäudeteil übertragen werden können und zum anderen die Gefahr eines Versagens des Kraftübertragungselementes aufgrund von Kerbwirkung entfällt, wie das bei Betonkraftübertragungselementen gemäß EP 2 481 867 A1 vorkommen kann. Ein massives Stahlteil gleicht Spannungsüberhöhungen an beschädigten Oberflächen aufgrund der Elastizität und des materialspezifischen Fließverhaltens von Stahl aus.Preferably, the force transmission element is formed as a solid steel part, which means that on the one hand large forces between the first and second building part can be transmitted and on the other hand eliminates the risk of failure of the power transmission element due to notch effect, as in concrete force transmission elements according to EP 2 481 867 A1 can occur. A solid steel part compensates for stress peaks on damaged surfaces due to the elasticity and material-specific flow behavior of steel.

Die oben beschriebenen Ausführungsformen der Erfindung können in beliebiger Weise miteinander kombiniert werden.The above-described embodiments of the invention may be combined with each other in any manner.

Wege zur Ausführung der ErfindungWays to carry out the invention

Wie aus Figur 1 zu ersehen ist, umfasst das Bauelement 1 eine im eingebauten Zustand sich vertikal erstreckende Trennplatte 2, die als Verbundplatte ausgebildet ist, die eine von zwei Kunststoffplatten 11, 13 umgebene Dämmschicht 12 aufweist. Die Trennplatte 2 hat eine Ausnehmung 14, die von einem L-förmigen Kraftübertragungselement 4 (siehe auch Fig. 2a) durchsetzt wird. Das Kraftübertragungselement 4 weist einen Flansch 5, der an der Trennplatte 2 anliegt und einen die Trennplatte durchsetzenden Steg 6 auf. Der Steg 6 ragt auf der dem zweiten Gebäudeteil B zugewandten Seite der Trennplatte 2 hervor und bildet die wesentliche Brücke für die Kraftübertragung zwischen den beiden sich beidseitig der Trennplatte 2 erstreckende Gebäudeteilen A, B. Der Steg 6 des Kraftübertragungselements 4 erstreckt sich somit von einem ersten Gebäudeteil A (in der Zeichnung rechts der Trennplatte) durch die Trennplatte 2 hindurch in einen zweiten Gebäudeteil B (links der Trennplatte). Der aus der Trennplatte 2 hervorstehende Bereich des Stegs 6 ist an seiner Unterseite und den Seitenflächen von einem Dämmmaterial 8 umgeben, während seine kraftübertragende Oberfläche durch eine Elastomerschicht 7 abgedeckt ist.How out FIG. 1 can be seen, the component 1 comprises a built-in state vertically extending partition plate 2, which is formed as a composite plate having an insulating layer 12 surrounded by two plastic plates 11, 13. The partition plate 2 has a recess 14 formed by an L-shaped power transmission element 4 (see also Fig. 2a ) is interspersed. The power transmission element 4 has a flange 5, which bears against the partition plate 2 and a partition plate passing through the web 6. The web 6 protrudes on the second building part B facing side of the partition plate 2 and forms the main bridge for the power transmission between the two sides of the partition plate 2 extending building parts A, B. The web 6 of the power transmission element 4 extends Thus, from a first part of the building A (in the drawing right of the partition plate) through the partition plate 2 into a second building part B (left of the partition plate). The protruding from the partition plate 2 region of the web 6 is surrounded on its underside and the side surfaces of an insulating material 8, while its force-transmitting surface is covered by an elastomer layer 7.

Die Gebäudeteile A, B werden entweder erst nach der Montage des Bauelements 1 vor Ort in Betonbauweise erstellt oder das Bauelement wird zusammen mit einem in Fertigteilbauweise erstellten Gebäudeteil an die Baustelle geliefert. Das Bauelement 1 mit seiner Trennplatte 2 dient dabei als Schalungsteil. So wird der Steg 6 des Kraftübertragungselements 4 bei der Herstellung des zweiten Gebäudeteils B von Beton umgossen, während der Flansch 5 des Kraftübertragungselements 4 und das Bewehrungselement 3 bei der Herstellung des ersten Gebäudeteils A von Beton umschlossen werden. Das Bauelement 1 wird somit beim Herstellen der Gebäudeteile A, B in diesen verankert.The building parts A, B are either created only after installation of the component 1 on site in concrete construction or the component is delivered to the construction site together with a prefabricated part of the building. The component 1 with its partition plate 2 serves as a formwork part. Thus, the web 6 of the power transmission element 4 is cast in the production of the second building part B of concrete, while the flange 5 of the power transmission element 4 and the reinforcing element 3 are enclosed in the production of the first building part A of concrete. The component 1 is thus anchored in the manufacture of the building parts A, B in this.

Sowohl der Flansch 5 als auch der Steg 6 des L-Profil-artigen Kraftübertragungselementes 4 sind flächig ausgebildet und bestehen aus massivem Stahl, was das Kraftübertragungselement 4 befähigt, große, zwischen dem ersten Gebäudeteil A und dem zweiten Gebäudeteil B auftretende Kräfte zu übertragen.Both the flange 5 and the web 6 of the L-shaped power transmission element 4 are formed flat and made of solid steel, which enables the power transmission element 4 to transmit large occurring between the first building part A and the second building part B forces.

An der der Trennplatte 2 abgewandten Seite des Flansches 5 ist ein Bewehrungselement 3 angeordnet, welches einen horizontalen Bewehrungsstab 9 aufweist. Das Bewehrungselement 3 umfasst weiterhin spiralförmige Abschnitte 10 aus Bewehrungsstahl, die im Zusammenhang mit der Figur 4 noch näher beschrieben werden. Die spiralförmige Abschnitte 10 sind mit dem Flansch 5 und mit dem Bewehrungsstab 9 verschweißt und erstrecken sich in den ersten Gebäudeteil A hinein.On the side facing away from the partition plate 2 of the flange 5, a reinforcing element 3 is arranged, which has a horizontal reinforcing bar 9. The reinforcing element 3 further comprises helical sections 10 made of reinforcing steel, which in connection with the FIG. 4 to be described in more detail. The spiral-shaped sections 10 are welded to the flange 5 and to the reinforcing bar 9 and extend into the first building part A.

Der Flansch 5 und der Steg 6 des in Figur 2a dargestellten Kraftübertragungselementes 4 schließen einen Winkel von 90° miteinander ein. Zur Verdeutlichung sind in der Figur 2a die Schwerpunktsebenen von Flansch 5 und Steg 6 sowie der von diesen Schwerpunktsebenen eingeschlossene Winkel α = 90° eingezeichnet. Der Steg 6 weist an seinem dem Flansch 5 abgewandten Ende eine konisch zulaufende Verjüngung auf.The flange 5 and the web 6 of in FIG. 2a shown power transmission element 4 enclose an angle of 90 ° with each other. For clarification are in the FIG. 2a the center of gravity of flange 5 and web 6 and the angle enclosed by these focal planes angle α = 90 ° drawn. Of the Web 6 has at its end facing away from the flange 5 a tapered taper.

Figur 2b zeigt eine Variante eines aus massivem Stahl bestehenden, L-Profil-artig ausgebildeten Kraftübertragungselementes 4 mit flächig ausgebildetem Flansch 5 und Steg 6. Der Steg 6 ist an seinem dem Flansch 5 abgewandten Ende leicht gekrümmt, wobei die Krümmung im eingebauten Zustand nach unten orientiert ist. Der Flansch 5 und der Steg 6 des in Figur 2b dargestellten Kraftübertragungselementes 4 schließen einen Winkel von rund 80° miteinander ein. Zur Verdeutlichung sind in der Figur 2b die Schwerpunktsebenen von Flansch 5 und Steg 6 sowie der von diesen Schwerpunktsebenen eingeschlossene Winkel α ≈ 80° eingezeichnet. FIG. 2b shows a variant of an existing solid steel, L-profile-like design power transmission element 4 with flat trained flange 5 and web 6. The web 6 is slightly curved at its end facing away from the flange 5, wherein the curvature is oriented in the installed state down , The flange 5 and the web 6 of in FIG. 2b illustrated power transmission element 4 include an angle of approximately 80 ° with each other. For clarification are in the FIG. 2b the center of gravity of flange 5 and web 6 and the enclosed by these centroid planes angle α ≈ 80 ° drawn.

Entsprechend der Breite des Bauelements sind mehrere horizontal nebeneinander angeordnete Kraftübertragungselemente 4 vorgesehen, wie dies in den Fig. 3 und 4 dargestellt ist.According to the width of the component a plurality of horizontally juxtaposed force transmission elements 4 are provided, as shown in the Fig. 3 and 4 is shown.

Fig. 3 zeigt eine perspektivische Ansicht des Bauelementes 1 von dem zweiten Gebäudeteil B aus, in welches die Stege 6 der beiden Kraftübertragungselemente 4 hineinragen. Das in der Zeichnung rechte Kraftübertragungselement 4 ist fertig montiert, d.h. umgeben von Dämmmaterial 8 und der Elastomerschicht 7 dargestellt, womit die Schalldämmung, insbesondere Trittschalldämmung verbessert werden. Der Steg 6 und dessen kraftübertragende Oberfläche 15 des linken Kraftübertragungselements 4 sind zur Anschauung unverkleidet dargestellt. Fig. 3 shows a perspective view of the component 1 from the second building part B, in which the webs 6 of the two power transmission elements 4 protrude. The right in the drawing power transmission element 4 is fully assembled, ie surrounded by insulating material 8 and the elastomer layer 7, whereby the sound insulation, in particular impact sound insulation can be improved. The web 6 and its force-transmitting surface 15 of the left power transmission element 4 are shown unclad for the sake of intuition.

Fig. 4 zeigt das Bauelement 1 von dem ersten Gebäudeteil A aus. Die Flansche 5 der beiden Kraftübertragungselemente 4 liegen an der Trennplatte 2 an. An der der Trennplatte 2 abgewandten Seite der Flansche 5 ist ein Bewehrungselement 3 angeordnet, welches einen horizontalen Bewehrungsstab 9 aufweist. Das Bewehrungselement 3 umfasst weiterhin spiralförmige Abschnitte 10 aus Bewehrungsstahl, die mit ihren Enden an den Flanschen 5 der beiden Kraftübertragungselemente 4 angeschweißt sind. Die spiralförmige Abschnitte 10 sind auch mit dem Bewehrungsstab 9 verschweißt und erstrecken sich in den ersten Gebäudeteil hinein. Der Bewehrungsstab 9 verbindet somit die beiden Kraftübertragungselemente 4, wodurch diese an der Baustelle gemeinsam und damit leichter zu handhaben sind. Fig. 4 shows the device 1 from the first part of the building A from. The flanges 5 of the two power transmission elements 4 are applied to the partition plate 2. On the side facing away from the partition plate 2 of the flanges 5, a reinforcing element 3 is arranged, which has a horizontal reinforcing bar 9. The reinforcing element 3 further comprises spiral-shaped sections 10 made of reinforcing steel, which are welded with their ends to the flanges 5 of the two power transmission elements 4. The spiral sections 10 are also welded to the reinforcing bar 9 and extend into the first part of the building. The reinforcing bar 9 thus connects the two power transmission elements 4, whereby they are common on the site and thus easier to handle.

Die spiralförmigen Abschnitte bewirken eine intensive Verankerung der Kraftübertragungselemente 4 an dem ersten Gebäudeteil A nach dessen Fertigstellung. Werden beide Gebäudeteile A, B vor Ort durch Betonieren hergestellt, so dient das Bauelement 1, insbesondere die Trennplatte 2, als ein Teil der Schalung.The spiral sections cause an intensive anchoring of the power transmission elements 4 on the first building part A after its completion. If both parts of the building A, B made on site by concreting, the component 1, in particular the partition plate 2, serves as part of the formwork.

Die Figuren 5a, 5b und 5c zeigen Varianten des Bauelements 1, dessen Bestandteile im Wesentlich dem in Figur 1 gezeigten Bauelement 1 entsprechen. Das Bauelement weist jeweils eine im eingebauten Zustand sich vertikal erstreckende Trennplatte 2 auf, die als Verbundplatte ausgebildet ist, die eine von zwei Kunststoffplatten 11, 13 umgebene Dämmschicht 12 aufweist. Die Trennplatte 2 hat eine Ausnehmung 14, die von einem L-förmigen Kraftübertragungselement 4 durchsetzt wird. Das Kraftübertragungselement 4 weist einen Flansch 5, der an der Trennplatte 2 anliegt und einen die Trennplatte durchsetzenden Steg 6 auf. Sowohl der Flansch 5 als auch der Steg 6 sind flächig ausgebildet und bestehen aus massivem Stahl. Der Steg 6 ragt auf der dem zweiten Gebäudeteil B zugewandten Seite der Trennplatte 2 hervor und bildet die wesentliche Brücke für die Kraftübertragung zwischen den beiden sich beidseitig der Trennplatte 2 erstreckende Gebäudeteilen A, B. Der Steg 6 des Kraftübertragungselements 4 erstreckt sich somit von einem ersten Gebäudeteil A (in der Zeichnung rechts der Trennplatte) durch die Trennplatte 2 hindurch in einen zweiten Gebäudeteil B (links der Trennplatte). Im Gegensatz zu dem in Figur 1 gezeigten Ausführungsbeispiel weist der Steg 6 an seinem dem Flansch 5 abgewandten Ende keine konisch zulaufende Verjüngung auf, sondern endet mit einer im eingebauten Zustand vertikalen Fläche. Anders als bei dem in Figur 1 gezeigten Ausführungsbeispiel weist das Kraftübertragungselement 4 in dem Steg 6 und Flansch 5 verbindenden Abschnitt eine Abrundung auf.The FIGS. 5a . 5b and 5c show variants of the component 1, whose components are essentially the in FIG. 1 shown component 1 correspond. The component has in each case a vertically extending partition plate 2 in the installed state, which is formed as a composite plate having an insulating layer 12 surrounded by two plastic plates 11, 13. The partition plate 2 has a recess 14 which is penetrated by an L-shaped force transmission element 4. The power transmission element 4 has a flange 5, which bears against the partition plate 2 and a partition plate passing through the web 6. Both the flange 5 and the web 6 are flat and made of solid steel. The web 6 protrudes on the second building part B facing side of the partition plate 2 and forms the main bridge for the power transmission between the two sides of the partition plate 2 extending building parts A, B. The web 6 of the power transmission element 4 thus extends from a first Building part A (in the drawing right of the partition plate) through the partition plate 2 through in a second building part B (left of the partition plate). Unlike the in FIG. 1 the embodiment shown, the web 6 at its end remote from the flange 5 no tapered taper, but ends with a vertical surface in the installed state. Unlike the one in FIG. 1 the embodiment shown, the force transmission element 4 in the web 6 and flange 5 connecting portion on a rounding.

Wiederum ist der aus der Trennplatte 2 hervorstehende Bereich des Stegs 6 an seiner Unterseite und den Seitenflächen von einem Dämmmaterial 8 umgeben, während seine kraftübertragende Oberfläche durch eine Elastomerschicht 7 abgedeckt ist. An der der Trennplatte 2 abgewandten Seite des Flansches 5 sind jeweils zwei voneinander beabstandete Bewehrungselemente 3 angeordnet, wobei in den Schnittdarstellungen der Figuren 5a, 5b und 5c jeweils nur ein solches Bewehrungselement sichtbar ist. Der in allen Ausführungsbeispielen der Figuren 5a, 5b und 5c vorgesehene Bewehrungsstab 9, der wie in Figur 4 gezeigt im eingebauten Zustand horizontal verläuft, verbindet mehrere Kraftübertragungselemente 4, wodurch diese an der Baustelle gemeinsam und damit leichter zu handhaben sind. Die Bewehrungsstäbe 16 sind mit dem Flansch 5 und mit dem Bewehrungsstab 9 verschweißt und erstrecken sich in den ersten Gebäudeteil A hinein, wodurch die Bewehrungsstäbe 16 eine intensive Verankerung der Kraftübertragungselemente 4 in dem ersten Gebäudeteil A nach dessen Fertigstellung bewirken. Je nach baulichen Anforderungen können die Bewehrungsstäbe 16 beispielsweise gewinkelt (Figur 5a), linear (Figur 5b) oder mit Krümmung (Figur 5c) in den ersten Gebäudeteil A hineinragen.Again, the protruding from the partition plate 2 region of the web 6 is surrounded on its underside and the side surfaces of an insulating material 8, while its force-transmitting surface is covered by an elastomer layer 7. At the side facing away from the partition plate 2 of the flange 5, two mutually spaced reinforcing elements 3 are arranged, wherein in the sectional views of FIGS. 5a . 5b and 5c only one such reinforcing element is visible in each case. The in all embodiments of the FIGS. 5a . 5b and 5c provided reinforcing bar 9, as in FIG. 4 shown in the built-in State runs horizontally, connects several power transmission elements 4, making them together at the site and thus easier to handle. The reinforcing bars 16 are welded to the flange 5 and the reinforcing bar 9 and extend into the first building part A, whereby the reinforcing bars 16 cause an intensive anchoring of the power transmission elements 4 in the first building part A after its completion. Depending on the structural requirements, the reinforcing bars 16 may, for example, be angled (FIG. 5a), linear (FIG. FIG. 5b ) or with curvature ( FIG. 5c ) protrude into the first part of the building A.

Die Erfindung ist durch die obigen Ausführungsbeispiele nicht beschränkt sondern kann im Rahmen der nachfolgenden Ansprüche variiert werden.The invention is not limited by the above embodiments but can be varied within the scope of the following claims.
