Definitions

  • the invention relates to a sound absorbing plate for the Interior design, with a front in which several holes for the passage of sound to a rear arranged Layer of sound absorbing material are incorporated.
  • the applicant's EP 0 388 355 shows a generic plate, in which grooves are worked into the front and back are who intersect and break through create the preferably made of wood plate. are these grooves V-grooves result in comparatively small Breakthroughs that are barely visible from a distance and in a veneer of a wooden surface. The grooves the front are still clearly visible and can be result in an undesired picture for the architect. Behind the plate is a sound absorbing layer, for example one Glass fiber mat, arranged.
  • a similar sound absorbing plate is from the GB 1,147,428 became known. These are in the front Grooves and milled into the back. The breakthroughs there are slits here. These slots are probably too Visible from a greater distance and can be used for the more sophisticated Interiors can be disruptive.
  • the invention has for its object a plate of the above Way of creating a wooden surface better comes into its own and still has a high absorption capacity ensures low frequency absorption in the main area.
  • the plate should be comparatively inexpensive to manufacture in series.
  • it should be possible to design the plate so that it can be used in escape rooms where there are high fire protection requirements consist.
  • the task with a sound absorbing panel is therefore solved that a front layer of wood or wood-like Material is arranged and the holes mentioned micro perforations are in this top layer, the diameter of these microperforations smaller than 1.5mm is that behind the top layer is a load-bearing layer with passages for the Sound recording is arranged and that the top layer and the supporting layer are firmly connected.
  • the holes in the plate according to the invention are microperforations, which can be produced for example by stamping and that interfere much less with a surface of a wood veneer than the usual grooves and bores.
  • the wood of the plate is preferably reduced to the cover layer arranged on the front. Since the proportion of wood is low, it can be sound-absorbing Plate made by appropriate choice of the load-bearing layer be that they also have high fire safety regulations corresponds.
  • the front layer and the load-bearing one Layer are firmly connected. Because of the low The thickness of the cover layer can be very flexible, and it is also possible to manufacture curved sound absorbing panels.
  • the micro perforations are die cuts, which penetrate the wood layer. These die cuts are preferred cylindrical breakthroughs.
  • the breakthroughs can too Holes. Such breakthroughs can be made with a suitable one Drill, punch or laser can be made. You can use a very small diameter, for example with a diameter of only 0.5 mm. Such punchings are then at a distance of, for example 2 to 3 m hardly visible. Dominates in the plate according to the invention the wood structure and the openings are barely noticeable.
  • the thickness of the cover layer is preferably less than 1.5 mm and is preferably in the range of 0.5 to 1.0 mm.
  • Such Top layer can for example consist of a multilayer Cover veneer can be made.
  • the plate can then be particularly inexpensive, light and non-flammable are produced if, according to a training of the Invention the load-bearing layer is cement-bound.
  • the carrier material can then be a plastic, for example recycled polystyrene his. Such a plate is then particularly light and nevertheless stable.
  • recycled plastic is ecologically very sensible and also reduces the costs for the Manufacturing. It has been shown that a plate with recycled Polystyrene can be made so stable that it is sure-footed.
  • the absorption capacity can be increased if according to a Further development of the invention in the supporting layer depressions are incorporated, each behind the microperforations are located. These depressions are, for example, grooves that are aligned accordingly to the microperforations. Behind each micro perforation is thus a recess in the load-bearing layer. These specializations are essential wider than the micro perforations and can absorb the sound and pass it on to the load-bearing layer.
  • the load-bearing layer and the top layer are according to a further training glued or glued together.
  • On the back of the supporting layer is preferably a further plate Breakthroughs, for example a hardboard, applied, preferably glued or glued. That sandwich Structure also allows the production of any in itself curved plate.
  • the load-bearing layer can be like the cover layer should be flexible and bendable. This is particularly so then the case when the supporting layer is made of recycled polystyrene exists that is bound with cement.
  • the polystyrene consists of different sized particles, between which passages exist.
  • FIG. 1 shows a plate 1 which has a membrane 2 as a cover layer, has a support layer 3 and a rear layer 4.
  • the membrane 2 is arranged on the front and thus forms the visible surface 9.
  • the plate 1 is bent according to FIG. 1, however, it can also be flat.
  • the cover layer is preferred a membrane, but can also be acoustically essentially non-vibrating layer, for example a glued one Veneer.
  • the membrane 2 is made of wood and is for example a multilayer plywood.
  • the thickness of the membrane 2 is preferred less than 1.5 mm and is preferably in the range from 0.5 to 1.0 mm.
  • the membrane 2 is regular or irregular Arrangement with a variety of continuous Perforations 5 provided. These perforations 5 preferably form cylindrical holes with a diameter smaller than 1.5 mm.
  • the diameter of the perforations 5 is preferably 5 in the range of 0.1 to 1.1 mm.
  • These perforations 5 have For example, a grid of 5 mm if the perforations according to Figure 1 are arranged in rows. However, these rows can also be offset and it is also conceivable the perforations 5 to be arranged irregularly. Usually with except for one edge 9a, the entire surface 9 is perforated.
  • the membrane 2 is firmly connected to the supporting layer 3, in particular glued or glued.
  • This load-bearing layer 3 4 consists of irregular, different large parts 12, which are made of a preferably lightweight material consist.
  • the material is preferably a recycled plastic, for example polystyrene.
  • the parts 12 are in cement 14 bound.
  • Cement 14 is irregularly distributed Passages 15 through which the sound from the surface 9 of the Plate 1 can be directed to the back 10.
  • the sound in the load-bearing layer 3 is to increase provided in the load-bearing layer 3 recesses 6, for example Incorporate V-shaped grooves, each behind the perforations 5 are arranged.
  • incident sound then passes through the perforations 5 into the recesses 6 and from these into the passages 15 and finally on the back 10 of the plate.
  • the supporting layer 7 is not combustible. Melt in case of fire the parts 12, the structure of the load-bearing layer 3 remains received however. Since the membrane 5 is very thin and therefore the Wood content is small, the plate 1 is also suitable for lining in escape rooms.
  • a layer 4 is arranged on the back of the load-bearing layer 3, which is, for example, a thin hardboard and has the breakthroughs 7.
  • Layer 4 is preferably also glued or glued to the load-bearing layer.
  • the membrane 2, the load-bearing Layer 3 and layer 4 are glued and sandwiched on top of each other.
  • another fleece 4 can be attached.
  • the superimposed Layers are pressed together in a molding press.
  • the layers are connected to each other and thus the plate is stable.
  • the layers are flexible and bendable , they can also be pressed into a curved plate.
  • Figure 1 shows a curved plate for example as an absorber and at the same time a light reflector is suitable.
  • the plate 1 according to the invention can, for example, as Ceiling or wall cladding can be used. More applications are door and cabinet door panels as well as free-standing Screens.
