Definitions
- the invention relates to a component for decoupling impact noise for flights of stairs, with an insulating bearing layer that can be inserted between a flight of stairs and a floor or platform that supports it.
- PE foam board Built-in elements known from the prior art for decoupling footfall sound usually consist of a PE (polyethylene) foam board.
- An elastomer bearing is embedded in this foam sheet.
- the PE foam sheet is rectangular, the elastomer bearing is designed as a narrow strip of 25 to 35 mm and is located in the middle of the PE foam sheet. Double-sided mounting tape is used to attach the foam board either between the flight of stairs and the landing or between the flight of stairs and the floor. In order to bring the PE foam sheet to the right size, it is cut to size. Under the influence of a vertical force, for example from stepping on a staircase, the elastomer bearing undergoes a vertical deformation, also known as deflection. The resulting impact sound is insulated accordingly.
- the DE1658897 relates to a support between components, in particular concrete components, with an elastically deformable bearing body and two superimposed sliding layers designed as plastic layers.
- One of the sliding layers has a smaller area and is connected to the bearing body, while the other sliding layer is connected to a carrier layer that lies directly on the bearing surface of one component.
- This sliding layer has a significantly smaller thickness than the bearing body.

Die Erfindung betrifft ein Bauelement zur Trittschallentkopplung für Treppenläufe mit einer zwischen einen Treppenlauf und einen diesen tragenden Boden oder ein diesen tragendes Podest einfügbaren Dämmlagerschicht.The invention relates to a component for decoupling impact noise for flights of stairs, with an insulating bearing layer that can be inserted between a flight of stairs and a floor or platform that supports it.
Aus dem Stand der Technik bekannte Einbauelemente zur Trittschallentkopplung bestehen in der Regel aus einer PE (Polyethylen)-Schaumplatte. In diese Schaumplatte eingebettet ist ein Elastomerlager. Die PE-Schaumplatte ist rechteckig, das Elastomerlager ist als schmaler Streifen von 25 bis 35 mm ausgebildet und in der Mitte der PE-Schaumplatte angeordnet. Zur Befestigung der Schaumplatte entweder zwischen Treppenlauf und Podest oder zwischen Treppenlauf und Boden dient ein doppelseitiges Montageklebeband. Um die PE-Schaumplatte auf die passende Grösse zu bringen, wird diese zugeschnitten. Unter Einwirkung einer vertikalen Kraft, beispielsweise durch Schritte auf einer Treppe, kommt es zu einer vertikalen Verformung des Elastomerlagers auch Einfederung genannt. Der resultierende Trittschall wird entsprechend gedämmt.Built-in elements known from the prior art for decoupling footfall sound usually consist of a PE (polyethylene) foam board.

An mindestens einer von dessen beiden Seiten, Oberseite und/oder Unterseite ist mindestens eine Schicht eines zweiten Elastomers vorgesehen, wobei diese Schicht dünner ausgebildet ist als das erste Elastomer. Das erste Elastomer hat eine höhere Shore A Härte als das zweite Elastomer.The structural element for flights of stairs according to the invention comprises an insulating layer which is introduced between the flight of stairs and a floor or a platform that supports it. The insulation bearing layer is designed as a foam-like material layer with a top and a bottom. A first elastomer is embedded in the foam material.

- The structural element according to one of the preceding Claims 1 to 4, characterised in that, the first elastomer (2) and/or the second elastomer (3) takes the form, for example, of rubber, or ethylene propylene diene monomer rubber (EPDM), or polyurethane (PU), with a different Shore A hardness.
- The structural element according to one of the preceding claims, characterised in that, the first elastomer (2) has an initial thickness of 10 mm to 20 mm.
- The structural element according to Claim 6, characterised in that, the embedded first elastomer (2) has a thickness reduction of 7.5 - 12.5 % under the weight of the stair flight (5), if the thinner layer of the second elastomer (3) has a thickness reduction of 20 - 50 %.
- The structural element according to one of the preceding Claims 1 to 7, characterised in that, on the upper face (10A) and on the lower face (10B) of the foam-shaped material layer (10), at least one layer of the second elastomer (3) is provided in the region of the first elastomer (2).
- The structural element according to one of the preceding Claims 1 to 8, characterised in that, at least one layer of the second elastomer (3) is provided on the upper face (10A) of the foamed material layer (10) in the region of the first elastomer (2), and an adhesive layer (4), for example an adhesive tape, is provided on the lower face (10B).
- The structural element according to one of the preceding claims, characterised in that, between the first elastomer (2) and the second elastomer (3) a nonelastomeric, essentially pressure-resistant, layer, in particular a sheet metal plate, is provided, which is significantly thinner than the foamed material layer (10) with the first elastomer (2) embedded therein, and the layer of the second elastomer (3).
- The structural element according to one of the preceding claims, characterised in that, a fibrous reinforcement is provided in the layer of the second elastomer (3) for purposes of stiffening against elongation.
- The structural element according to Claim 11, characterised in that, the layer of the second elastomer (3) has the fibrous reinforcement on the face that is facing towards the first elastomer (2).
- The structural element according to one of the preceding claims, characterised in that the foamed material layer (10) has in its upper face (10A) and/or its lower face (10B) at least one notch (11) for purposes of folding the component, preferably through 90°, and/or at least one incision (12) for purposes of facilitating a detachment of excess foamed material layer (10).
