Description

Die Erfindung betrifft ein Bauelement zum Einbau in Trennfugen von Gebäuden, insbesondere an Treppenpodesten, zur schalldämmenden und insbesondere auch kraftübertragenden Verbindung beiderseits angrenzender Gebäudeteile, bestehend aus einer Trennplatte zum Einbetonieren in die angrenzenden Gebäudeteile, wobei die Trennplatte einen mehrschichtigen Aufbau aus zwei Außenwänden und mindestens einem weiteren Zwischenelement aufweist.The invention relates to a component for installation in joints of buildings, especially on staircases, the sound-absorbing and especially force-transmitting connection on both sides adjacent parts of the building, consisting of a partition for concreting into the adjacent parts of the building, the partition a multilayer structure of two outer walls and at least one having another intermediate element.

Ein derartiges Bauelement ist durch die DE-195 42 282 bekannt. Dabei wird eine harte Trennplatte mit einem mehrschichtigen Aufbau aus relativ harten Außenlagen und zumindest einer demgegenüber weichen Zwischenlage und ohne direkte Verbindung der beiden Außenlagen miteinander eingesetzt. Hierbei sind die Bewehrungsstäbe durch die weiche Zwischenlage im Bauelement verankert, die so die Schwingungsübertragung zwischen den Außenlagen untereinander sowie zwischen den Außenlagen und den Bewehrungsstäben dämpft. Nachteilig hierbei ist, dass die Bewehrungsstäbe trotz ihrer Dämpfung gegenüber dem Bauelement wegen ihres durchgehenden, die beiden Gebäudeteile miteinander verbindenden Verlaufs dennoch eine hinreichend große Schwingungsübertragung zwischen den Gebäudeteilen verursachen. Darüber hinaus führt die Anordnung der Stäbe in der weichen Zwischenlage zu einer entsprechend großen Dicke des Bauelements und demgemäß zu einem großen gegenseitigen Abstand der angrenzenden Gebäudeteile.Such a device is through the DE-195 42 282 known. Here, a hard partition plate is used with a multi-layered structure of relatively hard outer layers and at least one contrast soft pad and without direct connection of the two outer layers together. Here, the reinforcing rods are anchored by the soft intermediate layer in the device, which dampens the vibration transmission between the outer layers with each other and between the outer layers and the reinforcing bars. The disadvantage here is that the reinforcing rods despite their attenuation relative to the component because of their continuous, the two parts of the building interconnecting course nevertheless cause a sufficiently large vibration transmission between the building parts. In addition, the arrangement of the rods in the soft intermediate layer leads to a correspondingly large thickness of the component and accordingly to a large mutual distance of the adjacent building parts.

Darüber hinaus ist aus der DE-195 39 356 ein Dämpfungselement zur Dämpfung von Körperschall bekannt, das alle Merkmale des Obergriffs des Anspruchs 1 aufweist.In addition, from the DE-195 39 356 a damping element for damping structure-borne noise is known, which has all the features of the preamble of claim 1.

Hiervon ausgehend liegt die Aufgabe der vorliegenden Erfindung darin, das eingangs beschriebene Bauelement dahingehend zu verbessern, dass es sich durch bessere Schalldämmung auszeichnet bei vergleichsweise kostengünstigerem Aufbau. Zudem soll der Einbau des Dämmelementes vereinfacht werden.Proceeding from this, the object of the present invention is to improve the device described above in that it is characterized by better sound insulation with relatively less expensive structure. In addition, the installation of the insulating element should be simplified.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein Bauelement mit den Merkmalen des Anspruchs 1. Indem die Trennplatte erfindungsgemäß durch Coextrusion der Außenwände und der flexiblen Innenstege hergestellt ist, ist es erstmals möglich, die üblicherweise aus Hart-Kunststoff, z.B. aus Hart-PVC bestehenden, harten Außenwände zusammen mit den flexiblen, vorzugsweise aus Weich-PVC bestehenden Innenstege trotz ihrer unterschiedlichen Aufgabenstellungen und Materialeigenschaften in einem einzelnen gemeinsamen Arbeitsvorgang einstückig herzustellen und so nicht nur die beiden Außenwände, sondern auch die beiden Gebäudeteile schalltechnisch zu entkoppeln. Dies führt zu einer deutlichen Reduzierung der Schwingungsübertragung. Das Bauelement bleibt trotzdem ausreichend stabil, sodass trotz der schmalen Bauweise des Bauelements bei Betondruck oder Schwingungen die Außenwände nicht miteinander in Kontakt kommen. Das erfindungsgemäße Bauteil zeichnet sich also durch eine optimale Anpassung an die gegensätzlichen Forderungen Festigkeit, Dämmwirkung und einfache Handhabung aus.This object is achieved according to the invention by a component having the features of claim 1. By making the partition plate according to the invention by coextrusion of the outer walls and the flexible inner webs, it is possible for the first time to use usually made of hard plastic, e.g. made of hard PVC, hard outer walls together with the flexible, preferably made of soft PVC inner webs in spite of their different tasks and material properties in a single joint operation in one piece and not only to decouple the two outer walls, but also the two parts of the building acoustically. This leads to a significant reduction of the vibration transmission. The device nevertheless remains sufficiently stable, so that despite the narrow design of the device at concrete pressure or vibrations, the outer walls do not come into contact with each other. The component according to the invention is thus characterized by an optimal adaptation to the conflicting requirements of strength, insulation effect and ease of handling.

Die Verwendung von Weich-PVC (PVC-P) für die Innenstege ermöglicht eine gute Schalldämmung in Kombination mit kostengünstiger Herstellung. Durch die Coextrusion können die Außenwände der Trennplatte aus ebenso kostengünstigen Werkstoffen, wie insbesondere aus dem oben erwähnten Hart-PVC, bestehen.The use of soft PVC (PVC-P) for the inner webs allows good sound insulation in combination with cost-effective production. By coextrusion, the outer walls of the partition plate of equally inexpensive materials, such as in particular from the above-mentioned rigid PVC exist.

Durch Verzicht auf ein durch die Trennplatte verlaufendes, die beiden Gebäudeteile verbindendes Bewehrungselement kann das Bauelement außerdem besonders schmal hergestellt werden, was den Einbau und die Handhabung des Bauelements wesentlich erleichtert und die statischen Eigenschaften verbessert.By dispensing with a running through the partition plate, connecting the two parts of the building reinforcing element, the device can also be made very narrow, which greatly facilitates the installation and handling of the device and improves the static properties.

Da das Bauelement möglichst schmal ausgeführt ist und die Bewehrung zwecks verbesserter Schalldämmung nicht durch das bauelement verläuft, weist vorteilhafterweise mindestens eine Außenwand der Trennplatte mindestens ein Befestigungselement für eine Bewehrung des an dieser Außenwand angrenzenden Gebäudeteils auf. Auf diese Weise kann die Platzierung des Befestigungselements für diese Konsolenbewehrung an der Außenwand der Trennplatte hinsichtlich Schalldämmung weiter optimiert werden. Zweckmäßigerweise lässt sich die Befestigung der Bewehrung noch weiter hinsichtlich Handhabung optimieren, indem die Befestigung der Bewehrung mittels einer formschlüssigen Verbindung wie etwa einer Clipverbindung erfolgt. Aus den gleichen Gründen kann es sich auch empfehlen, die Bewehrung an der Trennplatte schwenkbar zu lagern, was ebenfalls durch die Clipverbindung realisiert werden kann.Since the component is made as narrow as possible and the reinforcement for the purpose of improved sound insulation does not extend through the component, advantageously at least one outer wall of the partition plate has at least one fastening element for a reinforcement of the adjoining this outer wall part of the building. In this way, the placement of the fastener for this bracket reinforcement on the outer wall of the partition plate can be further optimized in terms of sound insulation. Conveniently, the attachment of the reinforcement can be further optimized in terms of handling by the attachment of the reinforcement by means of a positive connection, such as a clip connection. For the same reasons, it may also be advisable to mount the reinforcement on the partition plate pivotally, which can also be realized by the clip connection.

Weiterhin ist es vorteilhaft, dass die Trennplatte im vertikalen Querschnitt im Wesentlichen abgetreppt oder S-förmig ausgebildet ist. Dadurch überlappen das tragende Bauteil und das getragene Bauteil einander im Verbindungsbereich. Ein in einem im Wesentlichen horizontalen Abschnitt der Trennplatte angeordnetes Elastomerlager dient der Druckkraftübertragung zwischen den angrenzenden Gebäudeteilen und ersetzt so die schalltechnisch kritischen Bewehrungselemente, was wiederum zu verbesserter Schalldämmung führt.Furthermore, it is advantageous that the partition plate in the vertical cross-section is substantially stepped or S-shaped. As a result, the supporting member and the supported member overlap each other in the connecting portion. An elastomeric bearing arranged in a substantially horizontal section of the separating plate serves to transmit compressive force between the adjoining parts of the building and thus replaces the acoustic-sounding reinforcing elements, which in turn leads to improved soundproofing.

Um die Verankerung des Bauelementes insbesondere der Trennplatte in den angrenzenden Gebäudeteilen zu verbessern, weist die Trennplatte mindestens eine gegenüber einer Außenwand hervorstehende Hinterschnittkante auf, welche insbesondere einen T-förmigen Querschnitt hat.In order to improve the anchoring of the component, in particular the partition plate in the adjacent parts of the building, the partition plate has at least one opposite to an outer wall protruding undercut edge, which in particular has a T-shaped cross-section.

Aus Gründen des Brandschutzes kann es zweckmäßig sein, einen Brandschutzstreifen, insbesondere aus Intumeszenzmaterial, an den oberen bzw. unteren Enden des S-förmigen Verlaufs der Trennplatte anzubringen.For reasons of fire protection, it may be expedient to attach a fire protection strip, in particular of intumescent material, at the upper or lower ends of the S-shaped profile of the partition plate.

Da sich nunmehr die Bewehrungselemente nicht mehr durch die Trennplatte und die Trennfuge zwischen den beiden angrenzenden Gebäudeteilen erstrecken, können diese zumindest teilweise aus herkömmlichem Betonstahl bestehen, was die Herstellungskosten weiter reduziert.Since now the reinforcing elements no longer extend through the partition plate and the parting line between the two adjacent parts of the building, these can at least partially consist of conventional reinforcing steel, which further reduces the manufacturing cost.

Eine weiter verbesserte Verankerung der Bewehrungselemente in den angrenzenden Gebäudeteilen lässt sich durch zwei schlaufenförmig abgebogene Abschnitte der Bewehrung erreichen. Diese können in einer weiteren Ausbildung derart ausgestaltet sein, dass die Bewehrung einen horizontalen Verankerungsabschnitt aufweist und dass die Bewehrung an dem Befestigungselement der Trennplatte, insbesondere über den horizontalen Verankerungsabschnitt befestigt ist. Weiterhin können diese schlaufenförmige abgebogenen Abschnitte und der Verankerungsabschnitt miteinander verbunden sein. Dies ermöglicht sowohl eine bessere Verankerung der Bewehrung an der Außenseite der Trennplatte als auch eine gleichmäßigere Belastung der Trennplatte und damit ebenfalls eine verbesserte Schalldämmung. Die Trennplatte weist zudem eine Mehrzahl von flexiblen Innenstegen beispielsweise zumindest 4, insbesondere 6 auf. Die jeweilige Anzahl von Innenstegen wird in Abhängigkeit der jeweiligen Einbauposition ausgewählt und stellt ein Optimum aus Schalldämmung einerseits und Stabilität der Trennplatte andererseits dar. A further improved anchoring of the reinforcement elements in the adjacent building parts can be achieved by two loop-shaped bent portions of the reinforcement. These may be configured in a further embodiment such that the reinforcement has a horizontal anchoring section and that the reinforcement is fastened to the fastening element of the separating plate, in particular via the horizontal anchoring section. Furthermore, these loop-shaped bent portions and the anchoring portion may be interconnected. This allows both a better anchoring of the reinforcement on the outside of the partition plate as well as a more uniform load on the partition plate and thus also an improved sound insulation. The partition plate also has a plurality of flexible inner webs, for example at least 4, in particular 6. The respective number of inner webs is selected depending on the respective installation position and represents an optimum of sound insulation on the one hand and stability of the partition plate on the other.

Schließlich ist es zur Verbesserung der Kraftübertragung in horizontaler Richtung zur Verankerung der Trennplatte an dem getragenen Gebäudeteil von Vorteil, wenn die Trennplatte im Bereich des Elastomerlagers in ihrer das Elastomerlager bedeckenden Außenwand Aussparungen aufweist. Durch diese Aussparungen beaufschlagt der Beton des getragenen Gebäudeteils das Elastomerlager direkt und geht hierbei eine formschlüssige Verbindung mit dieser Außenwand und mit der Trennplatte ein.Finally, it is to improve the power transmission in the horizontal direction for anchoring the partition plate on the supported building part of advantage when the partition plate in the elastomeric bearing in its elastomeric bearing covering outer wall has recesses. Through these recesses, the concrete of the supported part of the building acts on the elastomeric bearing directly and in this case enters into a positive connection with this outer wall and with the separating plate.

Wie insbesondere Figur 1 zeigt, besteht das erfindungsgemäße Bauelement aus einer im Wesentlichen S-förmig ausgebildeten und im Wesentlichen vertikal verlaufenden Trennplatte 1, die den beiden angrenzenden Gebäudeteilen A und B zugewandte Außenwände 1a,1b aus Hart-PVC aufweist. Dazwischen befindet sich im im Wesentlichen horizontal verlaufenden Abschnitt 1c der Trennplatte 1 ein Elastomerlager 2. Weiterhin sind eine Mehrzahl von flexiblen Innenstegen 5 über das gesamte Profil der Trennplatte 1 verteilt und diese verbinden die beiden Außenwände 1a,1b. Diese flexiblen Innenstege 5 bestehen aus im Vergleich zu den harten Außenwänden weichem Material insbesondere Weich-PVC. Die Innenstege müssen kein besonderes Profil (bezogen auf den Vertikalquerschnitt) hierbei aufweisen, es empfiehlt sich aber, ihre Nachgiebigkeit durch eine abgewinkelte oder gekrümmte Profilierung zu verbessern.In particular FIG. 1 shows, the device according to the invention consists of a substantially S-shaped and substantially vertically extending partition plate 1, the two adjacent building parts A and B facing outer walls 1a, 1b made of rigid PVC. In between is located in the substantially horizontally extending portion 1c of the partition plate 1 is an elastomeric bearing 2. Furthermore, a plurality of flexible inner webs 5 are distributed over the entire profile of the partition plate 1 and these connect the two outer walls 1a, 1b. These flexible inner webs 5 consist of compared to the hard outer walls soft material in particular soft PVC. The inner webs need not have a particular profile (relative to the vertical cross-section) here, but it is advisable to improve their compliance by an angled or curved profiling.

Mit den Außenwänden 1a, 1b der Trennplatte 1 sind diese Innenstege 5 mittels Coextrusion verbunden. An den den Gebäudeteilen A, B zugewandten Seiten der Trennplatte befinden sich für eine bessere Befestigung des Bauelements in den Gebäudeteilen A, B Hinterschnittkanten 6, welche ein T-förmiges Profil aufweisen. Für die Befestigung einer Anschlußbewehrung 3,4 für die angrenzenden Gebäudeteile A, B sind an den jeweiligen Außenseiten der Trennwand Befestigungselemente 7 für eine Clipverbindung mit der Bewehrung vorgesehen. Über die Clipverbindung ist die Bewehrung 3,4 in den Befestigungselementen 7 schwenkbar angeordnet. Zum Zwecke des Brandschutzes weist die Trennplatte Brandschutzstreifen 9 auf.With the outer walls 1a, 1b of the partition plate 1, these inner webs 5 are connected by means of coextrusion. At the building parts A, B facing sides of the partition plate are located for better attachment of the device in the building parts A, B undercut edges 6, which have a T-shaped profile. For the attachment of a connection reinforcement 3.4 for the adjacent building parts A, B fastening elements 7 are provided for a clip connection with the reinforcement to the respective outer sides of the partition wall. About the clip connection, the reinforcement 3.4 is pivotally mounted in the fasteners 7. For the purpose of fire protection, the partition plate fire protection strip 9.

Die Bewehrungselemente 3,4 weisen jeweils einen sich in vertikaler Ebene erstreckenden, schlaufenförmig abgebogenen Abschnitt 3a, 4a und einen horizontalen Verankerungsabschnitt 3b, 4b auf, über den jede Bewehrung 3, 4 an dem Befestigungselement 7 der Trennplatte 1 befestigt ist. Hierbei sind die schlaufenförmig abgebogenen Abschnitte 3a, 4a und der Verankerungsabschnitt 3b, 4b miteinander verbunden.The reinforcing elements 3,4 each have a vertically extending, loop-shaped bent portion 3a, 4a and a horizontal anchoring portion 3b, 4b, via which each reinforcement 3, 4 is attached to the fastening element 7 of the partition plate 1. Here, the loop-shaped bent portions 3a, 4a and the anchoring portion 3b, 4b are interconnected.

Figur 2 zeigt eine 3-dimensionale Ansicht der Trennplatte 1 und der daran befestigten Bewehrungen 3,4. Hierbei besteht der horizontale Verankerungsabschnitt 3b, 4b der Bewehrung 3, 4 aus Edelstahl, während der schlaufenförmige Abschnitt 3a, 4a aus Schwarzstahl besteht. Die beiden Bewehrungselemente 3,4 sind einerseits über die ineinander übergehenden Verankerungsabschnitte 3b, 4b miteinander verbunden, andererseits sind an den anderen Enden der Bewehrungselemente 3,4 L-förmige Abwinkelungen 3c, 4c vorhanden, welche sich im Wesentlichen U-förmig überlappen. FIG. 2 shows a 3-dimensional view of the partition plate 1 and the reinforcements 3.4 attached thereto. Here, the horizontal anchoring portion 3b, 4b of the reinforcement 3, 4 made of stainless steel, while the loop-shaped portion 3a, 4a consists of black steel. The two reinforcing elements 3.4 are on the one hand connected to each other via the mutually merging anchoring sections 3b, 4b, on the other hand, at the other ends of the reinforcing elements 3.4 L-shaped bends 3c, 4c present, which overlap substantially U-shaped.

Des Weiteren sind im Bereich des horizontalen Abschnittes 1c der Trennplatte 1 mehrere fensterförmige Aussparungen 10 in der Außenwand 1b vorgesehen, durch die der Beton des Gebäudeteils B das sich über die gesamte Länge der Trennplatte erstreckende Elastomerlager 2 beaufschlagt.Furthermore, a plurality of window-shaped recesses 10 in the outer wall 1 b are provided in the region of the horizontal section 1 c of the partition plate 1, through which the concrete of the building part B acts on the elastomer bearing 2 extending over the entire length of the partition plate.

Zusammenfassend bietet die vorliegende Erfindung den Vorteil, ein Bauelement mit verbesserter Schalldämmung zur Verfügung zu stellen, welches bei vereinfachtem Aufbau kostengünstig hergestellt werden kann und einfach in der Handhabung ist.In summary, the present invention has the advantage of providing a device with improved sound insulation available, which can be produced inexpensively in a simplified structure and is easy to use.
