Definitions

  • the invention relates to a method for producing a sheet-like panel with sound-absorbing properties, wherein in a support plate channels are introduced, which connect a first side of the support plate with a second side of the support plate, and in which the first side of the support plate with first grooves and with second grooves is provided. Furthermore, the invention relates to a corresponding panel with sound-absorbing properties, with a support plate, arranged in the support plate channels connecting a first side of the support plate to a second side of the support plate and arranged in the first side of the support plate first grooves and second grooves.
  • a method and panel is for example from the DE 198 57 419 A1 known.
  • a measure of the quality of the acoustics in a room is the so-called reverberation time. This is the time that elapses until a sound level drops from a baseline by a predetermined amount.
  • the reverberation time depends on the frequency of the sound.
  • the panels have a good sound absorption capacity if they have a high porosity.
  • the penetrating sound is absorbed and distributed in the voids generated by the porosity.
  • the essential part of the sound in the panel is therefore absorbed and not reflected back into the room.
  • the sound-absorbing panels consist of a complex structure, wherein a cover layer forming the visible side of the panel is provided, which is provided with a plurality of holes. Through the holes, the sound penetrates into the interior of the structure of the panel.
  • the cover layer is applied to a support plate by gluing.
  • the cover layer which is already provided with the holes, provided with an adhesive layer.
  • the application of the adhesive layer has the disadvantage that the adhesive is applied flat, so that a part of the arranged in the cover layer holes is closed again.
  • the carrier plates used so far consist of a particularly porous material, ie not of a standard available material.
  • the production of sound-absorbing panels is therefore expensive, since a special plate material is used.
  • a chipboard with a particularly low density is used as the carrier plate.
  • the aim of this effort is in each case not to let the sound penetrated into the panel re-emerge on the room side, but to absorb it within the volume of the panel or to return it to the side of the panel facing away from the room.
  • a sound absorbing plate wherein in the plate channels are arranged, which connect a first side of the carrier plate with a second side of the plate.
  • grooves are arranged in the first side of the plate, wherein the grooves and the channels are arranged to each other, that the channels are connected to at least one groove. The sound conducted through the grooves is conducted through the channels to the other side of the plate and thus directed away from the first side, the visible side.
  • the plate described above has the disadvantage that this is only to be used together with a frame construction, since the actual sound absorption takes place in a stone or Glaswollmatraze. This can not easily connect to the plate, so that it requires an additional holding and reinforcing construction. Likewise, it is disadvantageous that the panel can be used only from one visible side, while the side facing away from the visible side is aligned only in the direction of a wall or a ceiling.
  • this plate Another disadvantage of this plate is on the one hand the lack of a suitable surface design, since the visible side of the panel with the groove and channel structure is directly visible. On the other hand, there is a disadvantage in that this panel, when cut to size and having a severing cut along one of the grooves, has only a small surface area on the side surface. This makes coating the side surface difficult or even impossible.
  • the invention is therefore based on the technical problem of improving a panel and a method for its production, so that the sound absorption properties are improved.
  • the above-indicated technical problem is solved according to the invention in a method according to claim 1 for producing a sheet-like panel with sound-absorbing properties of the type mentioned above in that the first grooves in a first Direction are aligned, wherein the first direction is at an angle between 10 ° and 45 ° to each one of the side edges of the support plate that the second grooves are aligned in a second direction, wherein the second direction at an angle between 30 ° and 45 ° extends to a respective one of the side edges of the support plate, and that the first grooves, the second grooves and the channels are arranged to each other, that the channels are respectively connected to one of the first grooves and one of the second grooves in an intersection region of the first and second grooves , In each case, the more acute angle to one of the side edges is decisive, the other side edge of the angle is naturally greater.
  • Embodiments of the method according to the invention are the subject of the dependent claims and are described below.
  • the side edge can be reliably and stably provided with a coating, in particular a cover layer, even up to the edge line with the first and second side.
  • a limit is called 10 °
  • the exact angle of 45 ° represents a particularly preferred embodiment because of the symmetry of the resulting groove and channel structure.
  • the grooves and channels have the function that the sound impinging on the surface is captured and directed, so that a portion of the sound is directed to the sound source side facing away from the panel.
  • the channels concentrate the sound, which then passes through the channels to the other side.
  • the channels are each connected to at least one groove. This means that the volume occupied by the channel overlaps with the volume enclosed by the groove. So there is a fluidic connection between the channel and the respective groove. In other words, in a plan view of the page, the groove and the respective channel overlap at least partially.
  • the introduction of the grooves is carried out in a conventional manner by cutting knife or cutter.
  • the channels are preferably introduced by drilling, but also by milling in the carrier plate.
  • laser processing is also possible. All other techniques for introducing such structures can also be used here.

  • the material of the carrier plate can be chosen almost arbitrarily.
  • the fundamental condition of the material is that a processing of the surfaces by the introduction of the grooves and channels is possible.
  • the support plate is preferably made of wood or a wood material, in particular a chipboard, an Oriented Strand Board (OSB), a medium-density fiberboard (MDF), a high-density fiberboard (HDF), a hardboard, a plywood or an inorganic bonded, preferably cement-bonded chipboard.
  • OSB Oriented Strand Board
  • MDF medium-density fiberboard
  • HDF high-density fiberboard
  • the carrier plate may consist of a plastic or of a plasterboard.

  • the thickness is in each case adapted to the acoustic problem to be solved or to the size of the surface to be covered. Since the carrier plate is intended to significantly produce the stability of the sound-absorbing panel, the thickness of the carrier plate has a corresponding importance.
  • the first grooves and the second grooves are respectively aligned in groups substantially parallel to each other.
  • the substantially parallel orientation means that the first and second directions are parallel. If the grooves are formed in a straight line, the direction can be easily determined. In a curvilinear course, however, the direction must be derived from the overall shape. This can be done for example by determining connecting lines between maxima of the curved course.
  • a substantially parallel course can also be given if the directions of two grooves run parallel, but the groove distances vary.
  • a particularly easy to manufacture construction of the support plate is achieved when the first direction and the second direction are aligned at a right angle to each other.
  • a further preferred embodiment of the method described is that the second side of the support plate is provided with grooves, wherein the grooves and the channels are arranged to each other, that the channels are connected to at least one groove.
