Abstract

The wall element has first (12) and second (14) wall leaves, which are spaced from one another by a framework of wooden uprights. The latter has at least one wooden post (16) with two parallel surfaces (20,22) which lie opposite one another, and which are connected to the first and second leaves. The post has a groove (34,36) in each of its opposing side surfaces (17,18). The grooves are parallel to the longitudinal axis of the post, and have a predetermined mutual spacing (S) in the direction which is normal to the parallel surfaces. They extend in planes which are nearly parallel to the parallel surfaces, and overlap in order to form a web (38).

Description

Die Erfindung betrifft ein Wandelement mit einer ersten Wandschale und einer zweiten Wandschale, die durch ein Holzständerwerk im Abstand voneinander gehalten sind, wobei das Holzständerwerk mindestens einen Holzstiel mit mindestens zwei Seitenflächen und mit zwei einander gegenüberliegenden Parallelflächen enthält, die mit der ersten Wandschale bzw. der zweiten Wandschale verbunden sind.The invention relates to a wall element with a first wall shell and a second wall cup made by a wooden stud frame are kept at a distance from each other, the wooden stud frame at least one wooden handle with at least two side surfaces and with two opposite one another Contains parallel surfaces with the first Wall shell or the second wall shell are connected.

Ein derartiges Wandelement wird häufig als Fertigbauteil hergestellt und zum Bau von Fertighäusern verwendet. Seine erste Wandschale und seine zweite Wandschale enthalten im allgemeinen eine Holzwerkstoffplatte, die mit Stahlklammern oder einem anderen Befestigungsmittel an den Parallelflächen mehrerer Holzstiele befestigt sind. An ein solches Wandelement besteht nun die Forderung, daß ein vorgegebenes Maß an Luftschalldämmung erreicht wird. Bisherige Lösungen sehen vor, daß die in den Zwischenraum zwischen Außenwand und Innenwand eingebrachten Dämmaterialien gute Schalldämmeigenschaften haben. Auch ein sandwichartiger Aufbau der Außenwand und der Innenwand kann unter Einsatz schalldämmender Materialien zur Schalldämmung beitragen. Such a wall element is often manufactured as a prefabricated component and used to build prefabricated houses. His first Wall bowl and its second wall bowl generally contain a wood-based panel with steel clips or a other fasteners on the parallel surfaces of several Wooden handles are attached. There is such a wall element now the requirement that a given level of airborne sound insulation is achieved. Previous solutions provide that the in the space between the outer wall and inner wall inserted insulation materials have good sound insulation properties. Also a sandwich-like structure of the outer wall and the Inner wall can be made using sound-absorbing materials Contribute sound insulation.

In der DE-A 32 45 652 ist eine Leiste für schalldämmende Hohlbauplatten beschrieben, die mehrere in Längsrichtung der Leiste verlaufende Schlitze hat, die sich einander überlappen. Die Leiste kann aus Holz bestehen und ermöglicht durch die eingebrachten Schlitze eine Erhöhung der Schalldämmung.DE-A 32 45 652 is a strip for sound-absorbing Hollow building boards described, the several in the longitudinal direction of the Groin has slit slots that face each other overlap. The bar can be made of wood and enables an increase in the through the slots Soundproofing.

Es ist Aufgabe der Erfindung ein Wandelement anzugeben, bei dem die Schallkopplung verringert ist, wobei dennoch eine hohe mechanische Stabilität erreicht wird.It is an object of the invention to provide a wall element which the sound coupling is reduced, although a high mechanical stability is achieved.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen angegeben.This object is achieved by the features of patent claim 1 solved. Advantageous further developments are in the dependent Claims specified.

Aufgrund der Überlappung der Nuten bildet sich im Inneren des Holzstiels ein sich in seiner Längsachse erstreckender Steg aus. Dieser Steg bildet die Verbindung zwischen zwei durch die Nuten getrennte Teile des Holzstiels. Schallwellen, die über den Holzstiel von der ersten Wandschale zur zweiten Wandschale oder umgekehrt gelangen, müssen diesen Steg durchlaufen und werden dabei gedämpft, da sie am Steg umgelenkt werden. Die schalltechnische Kopplung zwischen der ersten Wandschale und der zweiten Wandschale ist daher reduziert, bzw. die Schalldämpfung ist erhöht.Due to the overlap of the grooves, the inside of the Wooden handle a web extending in its longitudinal axis out. This bridge forms the connection between two the grooves separate parts of the wooden handle. Sound waves that over the wooden handle from the first wall bowl to the second Wall shell or vice versa must pass through this web and are dampened in the process since they are deflected at the web become. The acoustic coupling between the first Wall shell and the second wall shell is therefore reduced, or the sound absorption is increased.

Die Erfindung ist auch dadurch gekennzeichnet, daß die Mittelebene zwischen den zwei Nuten einen Abstand zu einer Parallelfläche hat, der das 0,2 bis 0,3-Fache des Abstandes zwischen den Parallelflächen beträgt. Diese Maßnahme, bei der die Nuten außermittig zwischen den beiden Parallelflächen des Holzstiels angeordnet sind, trägt zu einem verbesserten baustatischen Verhalten bei. The invention is also characterized in that that the center plane between the two grooves is a distance to a parallel surface that is 0.2 to 0.3 times the distance between the parallel surfaces. This measure, in which the grooves are off-center between the two parallel surfaces of the wooden handle are arranged to an improved structural behavior.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der einzigen Figur der Zeichnung erläutert. In der Figur ist als Beispiel ein Teil eines als Außenwand dienenden Wandelements 10 dargestellt, bei dem die Erfindung realisiert ist. Eine nach außen zeigende Wandschale 12 und eine nach innen zeigende Wandschale 14 werden in einem vorgegebenen Abstand A durch ein Holzständerwerk gehalten, welches Holzstiele 16 umfaßt. Das Holzständerwerk enthält im allgemeinen einen Obergurt und einen Untergurt (nicht dargestellt). An parallelen Seitenflächen 20, 22 der Holzstiele 16 sind Spanplatten 24, 26 befestigt. Auf der Wandschale 14 sind auf der Spanplatte 26 Gipskartonplatten 28 mittels Klammern (nicht dargestellt) befestigt.An embodiment of the invention is described below the only figure of the drawing explained. In the figure is an example of part of a wall element serving as an outer wall 10, in which the invention is implemented is. One wall shell 12 facing outwards and one inwards pointing wall shell 14 are at a predetermined distance A held by a wooden stud frame, which wooden stems 16 includes. The wooden stud frame generally contains an upper flange and a lower flange (not shown). On parallel side surfaces 20, 22 of the wooden handles 16 are chipboard 24, 26 attached. On the wall shell 14 are on the Chipboard 26 plasterboard 28 by means of clips (not shown) attached.

Auf der Spanplatte 24 der äußeren Wandschale 12 sind Polystyrolplatten 30 aufgeklebt. Auf diese Polystyrolplatten 30 ist Putzgrund 32 unter Verwendung von Glasseidengewebe aufgebracht.On the chipboard 24 of the outer wall shell 12 are polystyrene plates 30 glued on. On these polystyrene plates 30 is Plaster base 32 applied using glass silk fabric.

Wie in der Figur zu erkennen ist, enthält jeder Holzstiel 16 an seinen freien Seitenflächen 17, 18 Nuten 34, 36. Die Nuten 34, 36 verlaufen längs der Längsachsen der Holzstiele 16. Die Tiefe der Nuten 34, 36 erstreckt sich in der Figur parallel zu den Parallelflächen 20, 22. Von dieser Parallelität kann abgewichen werden, um z.B. einen keilförmigen Steg 38 auszubilden. Von den Parallelflächen 20 bzw. 22 aus gesehen, überlappen sich die Nuten 34, 36 und bilden den Steg 38 der Breite S. Die Länge L des Stegs ist von der Tiefe der Nuten 34, 36 abhängig und beträgt vorzugsweise L = 15 mm für Holzstiele 16 mit rechteckförmigem Querschnitt von 45 x 160 mm2 oder 80 x 160 mm2.As can be seen in the figure, each wooden handle 16 contains on its free side surfaces 17, 18 grooves 34, 36. The grooves 34, 36 run along the longitudinal axes of the wooden handles 16. The depth of the grooves 34, 36 extends parallel in the figure to the parallel surfaces 20, 22. This parallelism can be deviated from, for example to form a wedge-shaped web 38. Seen from the parallel surfaces 20 and 22, the grooves 34, 36 overlap and form the web 38 of the width S. The length L of the web depends on the depth of the grooves 34, 36 and is preferably L = 15 mm for wooden handles 16 with a rectangular cross-section of 45 x 160 mm 2 or 80 x 160 mm 2 .

Bezogen auf den Abstand A zwischen den Parallelflächen 20, 22 hat eine Mittellinie M durch den Steg S eine außermittige Position AM. Vorzugsweise beträgt der Abstand AM das 0,3-Fache von A. Durch die außermittige Anordnung der Nuten 34, 36 wird das statische Verhalten des Wandelements 10 gegenüber mittig angeordneten Nuten verbessert. Die Breite B der Nuten 34, 36 beträgt bei typischen Anwendungsfällen 2 bis 5 mm. Die Nuten 34, 36 werden durch Längssägeschnitte in den Holzstiel 16 erzeugt.Relative to the distance A between the parallel surfaces 20, 22, a center line M through the web S has an off-center position A M. The distance A M is preferably 0.3 times A. The eccentric arrangement of the grooves 34, 36 improves the static behavior of the wall element 10 compared to the centrally arranged grooves. The width B of the grooves 34, 36 is 2 to 5 mm in typical applications. The grooves 34, 36 are produced by longitudinal saw cuts in the wooden handle 16.
