Definitions

  • the present invention relates to a footfall sound insulation with a substantially even footfall sound insulation layer.
  • Such impact sound insulation is known in the prior art in various configurations and serve to prevent the transmission of noise, caused for example by walking or falling objects, in adjacent or underlying spaces. Furthermore, they should minimize space noise, which is reflected, for example generated by hard footwear back into the room.
  • a known footfall sound insulation is marketed by the applicant under the name "Schlüter ® Ditra-Sound".
  • This impact sound insulation comprises a newly formed impact sound insulation layer in the form of an incompressible heavy polyethylene-based film, the front and back of which is provided for anchoring tile adhesive each with a fleece.
  • the fleece arranged on the underside of the impact sound insulation layer is fastened to the substrate using a tile adhesive.
  • the floor covering is also laid on the fleece provided on the upper side of the footfall sound insulation layer using a tile adhesive, for example in the form of tiles or the like.
  • the present invention provides a footfall sound insulation of the type mentioned, which is characterized in that at the top of the footfall sound insulation layer, a plastic film is attached, which comprises a structuring with a plurality of hollow protrusions, wherein the projections have undercuts and / or a grid is attached to the top of the plastic film to clamp mortar applied to the top of the plastic film.
  • the existing impact sound insulation layer can be achieved with the impact sound insulation according to the invention a footfall sound improvement measure, which is comparable to that of known impact sound insulation.
  • An additional impact sound improvement measure is achieved by the cavities which are formed between the impact sound insulation layer and the plastic film due to the inventive structuring of the plastic film attached to the top of the impact sound insulation layer. Since the applied on the top of the plastic film mortar, which is applied in particular in the form of thin-bed mortar must be clamped to produce a solid bond with the impact sound insulation, it is necessary to mechanically fix this at the top of the plastic film.
  • the projections may have undercuts in which the mortar applied on the upper side of the plastic film is clamped, whereby a firm bond is produced between the plastic film and the mortar.
  • the undercuts can be generated for example by webs which protrude into the upwardly open cavities of the projections.
  • the cross-sections of the projections may be formed in the shape of a pyramid or truncated cone in order to achieve a dovetail-like clamping of the mortar in the projections in this way.
  • a grid may be attached, which is made for example of textile materials or plastic. Such a grid is partially embedded in the filling of the projections with the applied on the top of the plastic film mortar from the mortar, creating a mechanical interlocking between the mortar and the impact sound insulation is achieved. It is important to ensure that the mesh size of the grid is chosen such that they do not prevent complete filling of the upwardly open cavities of the plastic film with mortar.
  • the projections of the plastic film are according to an embodiment of the impact sound insulation according to the invention before the impact sound insulation layer and are open at the top. Accordingly, by filling the upwardly open hollow projections with mortar supporting stilts are formed, which lead in the installed state to improve the load transfer of loads acting on the floor covering in the ground and to a correspondingly high load capacity of the floor covering.
  • the underside of the footfall sound insulation layer can basically be laid loosely on the ground.
  • the impact sound insulation is mechanically firmly bonded to the substrate in order to achieve a composite impact sound insulation.
  • the underside of the footfall sound insulation layer for bonding with adhesive for example, pore-like and / or provided with a non-woven or a grid.
  • adhesive for example, pore-like and / or provided with a non-woven or a grid.
  • “Pore-like” means in this context that the impact sound insulation layer has pores or gaps due to their material composition, in which the adhesive can cling when laying the impact sound insulation.
  • the impact sound insulation layer has a smooth underside due to its material composition, which can not form an adhesive bond with the adhesive, then a fleece or a grid must be provided on the underside, which forms a mechanical bond with the adhesive.
  • the impact sound insulation layer preferably has a cork, plastic, rubber or fiber material. With such materials, good impact sound improvement measures could hitherto be achieved.
  • the impact sound insulation layer can be made compressible. With compressible materials can usually achieve higher impact sound improvement measures.
  • the thickness of the impact sound insulation layer is preferably at least 1 mm, more preferably at least 3 mm.
  • the total thickness of the impact sound insulation is between 4 and 15 mm.
  • the footfall sound insulation according to the invention may be plate-like or mat-like. In the latter case, the impact sound insulation can be provided in the form of a roll-up path.
