Definitions

  • the present invention relates to a plate-shaped sound absorbing member comprising a plate-shaped core material formed of a chipboard provided with longitudinally substantially parallel passage openings and connected to a plate-shaped first layer which is one of the two surfaces of the chipboard covered, and which is connected to a plate-shaped second layer, which covers the other of the two surfaces of the chipboard, and the first layer and / or the second layer are provided with grid-like holes arranged.
  • Such plate-shaped sound-absorbing elements are known. They are used, for example, for covering walls and ceilings and, in addition to the sound-absorbing effect, they also meet the requirements in terms of aesthetics. Since the hole diameters are very small, they are no longer visible to a viewer at a relatively small distance from the sound-absorbing elements, so that 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 observer only perceives the wood structure, the aesthetic effect is fully achieved.
  • a plate-shaped sound-absorbing element is known, in the plate-shaped core material along the surface extending slots are mounted. The layers attached to it are provided with holes, which must be aligned exactly on the slots.
  • the object of the invention is therefore to provide a plate-shaped sound-absorbing element, the production of which is inexpensive, compared to the known plate-shaped sound-absorbing elements has a lower weight and its SchallabsorbtionsSystem is improved.
  • the solution of this object is achieved in that the chipboard is extruded and the passage openings mounted therein are arranged substantially centrally in the chipboard, that the passage openings have a width that is greater than half the thickness of the wood chip board, and that the holes have a depth which is so large that those holes, which lie respectively in the region of a passage opening, open into this.
  • the thus formed plate-shaped sound-absorbing element is simple and inexpensive to produce, the weight is low, the Schallabsorbtionsire are optimal.
  • the provided with through holes wood chipboard is extruded and advantageously, the through holes have a circular cross-sectional shape.
  • the wood chips are each aligned in a plane which is perpendicular to the extrusion direction, whereby the attachment of the holes in this chipboard, in particular when they are punched, can be attached with little resistance.
  • the passage openings are arranged centrally in the chipboard, whereby the plate-shaped sound-absorbing element air is permeable to both sides mounted holes, which has a positive effect on the Schallabsorbtionslibrary.
  • a further advantageous embodiment of the invention is that at least one of the two layers, with which the chipboard is connected, consists of a wood veneer, to achieve a good strength of the plate-shaped sound-absorbing element, the wood veneer is connected to the chipboard so that the wood fibers are aligned substantially parallel to the passage openings.
  • the wood fibers of the wood veneer run transversely to the perpendicular to the extrusion Direction lying planes in which the wood chips of the chipboard are each, the risk of breakage of the plate-shaped sound-absorbing element is greatly reduced.
  • a simple production of such a plate-shaped sound-absorbing element is achieved in that the holes after bonding the first layer and the second layer can be attached to the chipboard by punching.
  • This plate-shaped sound-absorbing element 1 shows a part of a plate-shaped sound-absorbing element 1 according to the invention.
  • This plate-shaped sound-absorbing element 1 comprises a chipboard 2, which is provided with longitudinal, parallel aligned through holes 3. These passage openings 3 are mounted centrally in the chipboard 2 and have a circular cross-sectional shape. The diameter W of these passage openings 3 is greater than half the thickness D of the chipboard 2.
  • passage openings 3 may also have other cross-sectional shapes, for example rectangular or oval.
  • the chipboard 2 is provided with a plate-shaped first layer 4, which is connected, for example, by gluing with 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, whereby the connection is achieved by gluing here as well.
  • Both the plate-shaped first layer 4 and the plate-shaped second layer 5 are provided with grid-like holes 6. These holes 6 have a diameter which is about 0.6 mm, while the mutual distance of the holes 6 is about 3 mm.
  • the first layer 4 consists in the present embodiment of a wood veneer
  • the second layer 5 may also consist of a wood veneer, but it may also consist of any other suitable material, for example on a plastic basis.
  • FIGS. 2 and 3 a longitudinal section (parallel to the passage openings 3) and a cross section (transverse to the passage openings 3) are shown.
  • the production of the chipboard 2 with the through holes 3 takes place in one operation by extrusion.
  • the extrusion direction is consistent with the longitudinal directions of the through holes 3.
  • the chips 7, as can be seen in Figs. 2 and 3 are practically aligned in planes which are perpendicular to the longitudinal directions of the through holes 3 and consequently to the extrusion direction. This can be seen in particular from FIG. 2.
  • FIG. 3 shows that the chips are not aligned in the plane itself.
  • the chipboard 2 can break more easily when subjected to flexing transversely to the through-holes 3, than, for example, in a bending load along the through-holes 3.
  • the plate-shaped first layer 4 and the plate-shaped second layer 5, if they consist of a Wood veneer consist, so placed on the chipboard and connected to this, that the fibers of the wood veneers are aligned in the longitudinal direction of the through holes 3, whereby a higher strength of the plate-shaped sound-absorbing element is achieved.
  • the holes 6 are attached after joining the first layer 4 and the second layer 5 with the chipboard 2 by punching.
  • the plate-shaped element in a known manner passes through a punching device having, for example, three rows of punches 7, as shown in FIG. 2 can be seen.
  • the holes 6 are first placed on the one side and on the other side in the plate-shaped element on a second pass.
  • the punches which have a conical tip whose cone angle is about 90 °, penetrate about one third of the thickness D of the chipboard 2 in this. This ensures that the holes 6 thus formed, which each lie in the region of a passage opening 3, open into this.
  • the plate-shaped sound-absorbing element is thus permeable to air, measurements have shown that such a plate-shaped sound-absorbing element has a better sound-absorbing behavior, especially because of the through holes, as a corresponding element in which the chipboard has no through holes.
  • the puncturing of the holes 6 in the plate-shaped element 1 can be achieved with a relatively small force. This results from the effect, as has been described above, that the wood chips are aligned in planes that are transverse to the extrusion direction and thus to the through holes 3 by the extrusion of the chipboard 2 with the through holes 3. Therefore, the wood chips do not have to be broken, but they are more or less pressed apart, whereby the resistance that must be overcome by the punches, relatively low.
  • a plate-shaped sound-absorbing element 1 which can be produced inexpensively, which is a low Has weight, which has a good sound-absorbing behavior and which fully meets the aesthetic requirements.
  • this plate-shaped sound-absorbing element has the required strength.
