Definitions

  • Such plate-shaped sound-absorbing elements are known. They are used, for example, to cover walls and ceilings and meet the requirements in addition to the sound-absorbing effect in aesthetic terms. Since the hole diameters are very small, they are for a viewer at a relatively short distance from the sound absorbing Elements no longer visible, leaving only the structure of the surface of the material used for the visible layer is perceived. If this layer is formed from a wood veneer, the viewer takes only the wood structure is true, the aesthetic effect is fully achieved.
  • Such plate-shaped sound absorbing elements are because the core material is made of a chipboard, relatively heavy, what their Assembly makes it difficult. In addition, the sound absorption capacity is more Elements are often not sufficient.
  • this object is achieved by that the chipboard with longitudinal, essentially parallel Through openings are provided which have a width that is greater than half the thickness of the chipboard, and that the Holes have a depth that is so large that those holes, each lie in the area of a through opening, open into this.
  • the one provided with through openings is advantageous Chipboard extruded and have the through openings circular cross-sectional shape.
  • the wood chips are each in a plane that is perpendicular is to the extrusion direction, are aligned, whereby the attachment of the Holes in this chipboard, especially when punched low resistance can be attached.
  • Another advantageous embodiment of the invention consists in that at least one of the two layers with which the chipboard is connected from a wood veneer, being used to achieve a good Strength of the plate-shaped sound-absorbing element, the wood veneer is connected to the chipboard in such a way that the wood fibers essentially are aligned parallel to the through openings. Get lost the wood fibers of the wood veneer are perpendicular to the direction of extrusion lying levels, in which the wood chips of the wood chipboard each lie, the risk of breakage of the plate-shaped sound-absorbing element is greatly reduced.
  • these through openings 3 can also have other cross-sectional shapes, e.g. rectangular or oval. she do not have to be arranged centrally in the chipboard 2, but can e.g. B. be offset from each other.
  • the chipboard 2 has a plate-shaped first layer 4 provided, for example, by gluing to the chipboard 2 and which covers one of the two surfaces of the chipboard 2, while the other of the two surfaces of the chipboard 2 with a plate-shaped second layer 5 is provided, the connection here too is achieved by gluing.
  • Both the plate-shaped first layer 4 and the plate-shaped second layer 5 are provided with holes 6 arranged in a grid. These holes 6 have a diameter that is approximately 0.6 mm while the mutual distance between the holes 6 is about 3 mm.
  • FIG. 2 and 3 is a longitudinal section (parallel to the through openings 3) and a cross section (transverse to the through openings 3) shown.
  • the production of the chipboard 2 with the through openings 3 is done in one operation by extrusion.
  • the extrusion direction agrees with the longitudinal directions of the through openings 3.
  • the chips 7, as shown in FIGS. 2 and 3 can be seen, are practically aligned in planes that are perpendicular to the Longitudinal directions of the through openings 3 and consequently to the extrusion direction stand. This can be seen in particular from FIG. 2.
  • the top view on the chips according to FIG. 3, in which on the levels described above The chips being looked at shows that the chips are not in the plane itself are aligned.
  • a plate-shaped sound-absorbing element 1 is thus created, that can be manufactured inexpensively, which is a small Has weight, which has a good sound-absorbing behavior and which fully meets the aesthetic requirements. Also points this plate-shaped sound-absorbing element has the required strength on.
