Definitions

  • the invention relates to an acoustic panel according to the preamble of independent claim 1 and to a method for producing an acoustic panel according to the preamble of independent claim 11.
  • Acoustic elements for use as a wall or ceiling covering are used to influence the room acoustics.
  • the room acoustics are influenced by sound waves radiated directly from a sound source and sound waves reflected by walls, ceilings and furnishings that occur in a room.
  • Decisive for the improvement of the room acoustics is the reduction of the direct sound reflection in the room.
  • the degree of sound absorption of the respective materials serves as a measure of this.
  • Acoustic elements are intended in particular for use in meeting rooms, entrance areas, restaurants, offices, concert halls, meeting rooms, schools or sports facilities.
  • Such an acoustic element is, for example, from the DE 10 2014 207 852 A1 discloses a panel with a Holzmaschinedämmplatte, a wood-based panel and a resting on the wood-based panel visible solid wood surface, wherein in the solid wood surface and the wood-based panel slits are incorporated into the wood fiber insulation.
  • a NutfederNK is provided in the wood-based panel.
  • Further acoustic elements are, for example, from the DE 20 2009 016 944 U1 , of the EP 2 216 773 B1 and the WO 2006/056351 A1 known.
  • Known acoustic panels have a multilayer structure and have a viewing surface directed towards the room and provided with perforations or other recesses, which is designed so that the sound waves penetrate through them into an absorber surface and run there.
  • the structural design of the known panels is designed to achieve a high efficiency particularly expensive.
  • Each panel is designed as an independent component and provided for each separate attachment to the wall or ceiling.
  • the production of visually appealing, acoustically particularly effective and precisely mountable acoustic panels, ie acoustic panels can be produced by means of mountable without offset covering surfaces is complicated and costly with the known acoustic panels and manufacturing processes.
  • the invention is therefore an object of the invention to provide a structurally particularly simple and inexpensive to manufacture acoustic panel can be formed with the offsetless and visually appealing surfaces. It is also an object to provide a corresponding method for producing such an acoustic panel.
  • the invention achieves the object by an acoustic panel having the features of claim 1 and a method having the features of claim 11.

  • the design of the acoustic panel with corresponding locking profiles makes it possible in a particularly simple manner to produce wall and ceiling coverings with non-offset surfaces, since the locking profiles guarantee an offsetless connection of the acoustic panels. Even in the case of unevenness on the direct wall or ceiling surface, or in the fastening means for the acoustic panels, the surface visible in the space produced by the acoustic panels is without offset. Due to the Verrieglungsprofile is also ensured that the surface remains permanently offset and the positioning of the individual panels to each other permanently consistent, so that, for example, even in setting activities of the building and / or climate-induced changes in individual building materials, such as the wood-based panel, the surface of the coating produced remains permanently consistent. By offset is meant that the panel surfaces are arranged in a plane.
  • the acoustic panel according to the invention can be produced by a method matched to the acoustic panel, which method is particularly cost-effective, since individual method steps are at least partially known from the production of floor, wall or ceiling laminates.
  • a further particular advantage of the inventive acoustic panel is that, alternatively, a floor, wall or ceiling laminate known per se and cost-effective to produce can be further processed into an inventive acoustic panel in a particularly cost-effective manner by modification with the corresponding recesses and connection to a lower-side absorber unit can.
  • the particularly simple structural design of the inventive acoustic panel thus makes it possible to modify any known as wall, ceiling or floor laminate panel in a simple and cost-effective manner to the acoustic panel.

  • the connection means receptacle can be introduced into the wood-based panel or the absorber unit.
  • the kausstoffausNeillung is introduced at the same time or after the profiling or the introduction of the base plate passing through recesses, whereby a particularly efficient production is possible.
  • the connecting means recess is formed, for example, as a groove extending in the longitudinal direction of the panel.
  • Fig. 1 and 2 show an acoustic panel 1 of a base plate 2, ie a coated, divided into plate sections wood-based panel 2a, here an MDF board.
  • the base plate 2 has on a top side 5 a cover layer (not shown here), here a decorative layer and a structure layer arranged above the decorative layer (not shown here) for producing a haptic surface.
  • a cover layer not shown here
  • a structure layer arranged above the decorative layer (not shown here) for producing a haptic surface.
  • a Chems not shown here
  • locking profiles 13a, 13b are mutually corresponding, lockable with each other rotary-swivel profiles (see also Fig. 5 ), via which the acoustic panel 1 can be connected to other acoustic acoustic panels 1 (not shown here) without binder to form a surface without offset.
  • correspondingly shaped locking profiles 10 are arranged for vertical Aufratetzen.
  • the decorative layer is designed as a lacquer layer.
  • the counteracting layer is also adapted to this as a lacquer layer.
  • the decorative layer shows a wood decor (not shown here).
  • the absorber unit 7 is interruption-free, ie continuous (up to the locking profiles adjacent) arranged over the bottom 6 of the base plate 2.
  • the absorber unit 7 is connected to the underside 6, here on the lacquer layer formed as a countermix, by means of an adhesive layer (not shown here), here a melt adhesive layer.
  • the base plate 2 passing through recesses 8 are introduced.
  • the recesses 8 are formed as aligned in the longitudinal direction of the acoustic panel 1 slots.
  • the recesses 8 are only partially introduced into the base plate 2.
  • the recesses 8 are exposed both in the edge region 9a, 9b of the end faces 3a, 3b and in a central region 9c of the base plate 2, so that the base plate 2 has no recesses 8 in the edge regions 9a, 9b.
  • a particularly good stability of the acoustic panel 1 is ensured.
  • the recesses 8 protrude through the entire base plate 2 and through the adhesive layer in the absorber unit 7, so that on the visible side of the acoustic panel 1 incident sound waves (not shown here) can be passed through the recesses 8 to the absorber unit 7.
  • the base plate 2 has a height of 6 mm and the absorber unit 7 has a height of 8 mm.
  • Fig. 3 to 5 show a second embodiment of the acoustic panel 1 with over the entire length of the acoustic panel 1 extending recesses 8.
  • the recesses 8 are also arranged in a slot shape and aligned parallel to each other in the longitudinal axis direction.
  • At the bottom 6 of the base plate 2 are reinforcing elements 11 (in Fig. 3 represented by dashed lines) which extend transversely to the longitudinal direction of the acoustic panel 1 and are connected thereto.
  • the reinforcing elements 11 are also formed as strips, here corresponding to the base plate 2 made of MDF, and glued to the bottom 6. Between the reinforcing elements 11 absorber elements 15 of the absorber unit 7 are arranged.
  • the height of the absorber unit 7 is (not shown here) about 10% higher than the height of the reinforcing elements 11. Due to the over the entire length of the acoustic panel 1 extending recesses 8 is a particularly good sound absorption by the acoustic panel 1 when hitting sound waves reached. In addition, this embodiment of the acoustic panel 1 offers the possibility of forming jointless acoustic panel surfaces with uninterrupted recesses 8.
  • the recesses 8 extend through the entire base plate 2 through into the individual absorber elements 15 of the absorber unit 7 or into the reinforcing elements 11 and form in these grooves 14.
  • the recesses 8 For a uniform appearance are also in the longitudinal outer area of the acoustic panel 1 extending into the wood-based panel 2a extending DekorausEnglishept 12, which are formed on the one hand for a uniform appearance of the acoustic panel 1 and the other for a dispersion of the impinging sound waves.
  • acoustic panel 1 has according to the embodiment Fig. 1 and 2 on the end faces 4a, 4b and on the longitudinal sides 3a, 3b in each case corresponding locking profiles, which are designed as a rotary-swivel profiles or as a vertical locking profiles 10.
