Definitions

  • the previously known wooden building board has a carrier layer, the at least one, at least partially arranged by rust and from each other having spaced strips or the same individual elements formed layer. In the intermediate spaces formed between adjacent individual elements sound absorbing material is provided, which may be made for example of a strip-shaped cut softboard.
  • the carrier layer of the previously known wooden building board is connected to a viewing panel which faces the room in the position of use and, after being connected to the carrier layer, is provided with openings which are oriented crosswise to the spaces containing the sound absorption material.
  • Previously known timber board may have a faceplate, which can be designed individually depending on the desired appearance in terms of material, color and / or surface design. Likewise, the openings exposing the sound absorbing material can be individually incorporated into the Visible plate are introduced. Since the sight plate is initially formed closed and is provided only with openings in accordance with the wishes of the user before installation, a large supply of similar wooden boards can be kept, so long delivery times, which can be caused by individual production of the entire timber board, are avoided.
  • the previously known wooden building board can therefore be produced in a variety of ways in an aesthetically pleasing appearance.
  • the visual position on its side facing the room on a structured for diffuse scattering of the reflected sound and brushed for this purpose and / or blasted surface Due to the strong surface structure on the visible side of the wooden building board according to the invention, not only a lively and aesthetically pleasing appearance is favored, but also a diffuse scattering of the reflected sound can be achieved by the strongly structured surface, whereby the speech intelligibility and the musical listening pleasure can be substantially improved because all frequencies are distributed optimally in the room.
  • the invention provides that at least a larger number of openings provided in the visible position extend at least over half the thickness or longitudinal extension of the sound absorption material. While in the above-mentioned prior art, the openings have always been continued only to the surface of the sound absorbing material, the openings extend at least half the thickness or longitudinal extent of the sound absorbing material and thus deep into the sound absorbing material in the wood wall panel according to the invention. These apertures reaching into the sound absorption material so deeply have an optical depth effect which substantially improves the appearance of the wood building panel according to the invention; However, it is crucial that these openings, which penetrate deep into the sound absorption material, are also distinguished by an improved sound-absorbing effect. By virtue of this recessed scratching of the visual position, the sound waves penetrating into the openings can also project laterally or horizontally into the sound absorption material of the carrier layer located behind the viewing position.
  • the wooden building board according to the invention is characterized by the fact that a particularly high sound absorption can be achieved with a small thickness of this wooden building board and in particular its visual position, which in particular in noble and high-quality viewing layers to a material savings and thus to a Cost reduction can result. Due to the achievable high sound absorption values, however, it is also possible, if required, to achieve quantity savings over the entire absorber surface or better absorption values for the same area. These improved absorption values can also be achieved with thinner or lighter and correspondingly handy wooden building panels, for example in wood interior construction.
  • the carrier layer is formed as a flat continuous layer of alternating slats or similar individual elements on the one hand and sound absorption material on the other.
  • a preferred embodiment according to the invention therefore provides that the carrier layer is formed from at least a first layer of spaced apart and / or mutually parallel slats or similar individual elements and that at least in a larger number of spaces formed between the spaced apart individual elements preferably slatted cut sound absorbing material is arranged, and that abut the sound absorbing material on the adjacent longitudinal sides of the gap defining individual elements.
  • the distances between the openings can be applied in a wide range of variation, when the individual elements and the sound absorption material each measure about 50% of the surface of the carrier layer level.
  • a preferred embodiment according to the invention provides that the sound absorption material is made of a wood fiber board and in particular of a soft fiber board.
  • FIG. 1 to 12 Different versions 1, 2 and 3 of a wooden building board are shown, which is designed as an acoustic element and in particular as an acoustic panel and intended for mounting on the ceilings and / or walls of a room.
  • the timber building panels 1, 2, 3 shown here have gaps 4, of which at least a subset is provided with sound absorption material 5.
  • the sound absorption material 5, which may preferably be made of a particular strip-shaped cut wood softboard, here fills the gaps 4 completely.
  • the wood building panels 1, 2, 3 have at least one support layer 6, in which the intended for receiving sound absorption material 5 spaces 4 are provided.
  • the timber boards 1, 2, 3 further carry a in the position of use facing the room viewing position 7, which is provided with openings 8, which extend to the sound absorption material 5 having gaps 4 of the support layer 6.
  • the wooden panels 1, 2, 3 have on the side facing the room of their sight layer 7 a highly structured surface, which is intended for diffuse scattering of the reflective sound.
  • the visible layer 7 is visually brushed or blasted with abrasive media, such that the visual position 7 by a projecting annual rings and by contrast recessed annual ring spaces has a highly structured surface.
  • openings 8 which extend so deeply into the sound absorption material 5, have an optical depth effect which substantially improves the appearance of the wood building boards 1, 2, 3; but it is crucial that these deep 8 in sound absorbing material openings 8 are also characterized by an improved sound-absorbing effect.
  • the sound waves penetrating into the openings 8 can also project laterally or horizontally into the sound absorption material 5 of the carrier layer 6 located behind the visible layer 7.
  • the highly structured surface of the view layer 7 on the one hand and the deep 8 extending into the sound absorption material openings 8 on the other hand complement each other such that a particularly high sound absorption can be achieved, which in particular can lead to a saving of material and thus to a cost reduction with noble and high-quality sighting layers. Due to the achievable high sound absorption values, however, it is also possible, if required, to achieve quantity savings over the entire absorber surface or better absorption values for the same area. These improved absorption values can also be achieved with thinner or lighter and correspondingly handy wooden building panels, for example in wood interior construction.
  • the carrier layer 6 has a plurality of individual layers formed at least partially by rust-like arranged individual elements 9.
  • the total thickness of the sound absorption material 5 can be varied and thus the absorption behavior of the wood building panels 1, 2, 3 can be determined.
  • the sound absorption material 5 can be held in each case clamping between the individual elements, so that separate fasteners for the sound absorption material 5 or an adhesive connection are not required and still a secure hold of the sound absorption material 5 is secured to the support layer 6.
  • the carrier layer 6 of the wooden building boards 1, 2, 3 may consist of at least one first layer of individual elements arranged laterally spaced apart from one another and a second layer of individual elements laterally spaced apart from one another Interspaces between the individual elements of at least one of the layers form the spaces 4 for the sound absorption material 5.
  • the preparation of the carrier layer 6 is particularly easy possible by a number of similar, lath-like individual elements 9 aligned and the individual elements 9 adjacent layers connected to each other at their points of contact, for example, glued.
  • the visual position 7 can be adapted to individual design wishes in terms of material, structure and color.
  • the visible layer 7 is a Holzzeil slaughterplatte, a wood-based panel or the like plate, which preferably consists of softwood and / or exotic wood.
  • connection between the carrier layer 6 and the visible layer 7 is a glue connection.
  • no nails or the like connecting elements are visible on the outside of the visible layer 7, resulting in a harmonious and high-quality overall appearance of the timber boards 1, 2, 3.
  • the projecting to the sound absorbing material 5 openings 8 are designed here as slots, wherein the slot width, the slot length and / or the distance between adjacent slots are variable to each other.
  • the introduction of the openings 8 is particularly simple and quickly possible if the openings 8 are formed by shegeschlitze, which are incorporated after bonding with the carrier layer 6 in the face sheet 7.
  • the slots need not be longitudinal slots and in particular not the parallel longitudinal slots shown here. Conceivable, for example, arcuate, circular or spiral slots.
  • the openings 8 are designed as holes, cutouts or the like recesses, the dimensions of the recesses are variable to the view layer 7.
  • particularly individually designed wooden panels 1, 2, 3 can be realized, for example, with circular, rectangular or the like recesses with geometric shapes. Conceivable are combinations of different trained recesses.
  • the wooden wall panel shown here can be configured in several layers multilayered. While the in Fig. 3 illustrated timber board only from the striped, scribed or otherwise provided with openings 8 layer of vision 7 and the spaces 4 for the sound absorption material 5 having support layer 6 is formed, the wood panels 1 and 2 are configured multi-layered and have on their the viewing position 7 opposite side a cover layer 10, with the wooden panels 1, 2 facing the wall or ceiling.
  • cover layer 10 is formed in the timber board 2 from thin, spaced apart adjacent board layers, the cover layer 10 is occupied in the timber board 1 by closed or with thin and without spacing adjacent board layers.
  • the cover layer 10 of the timber panels 1, 2 improves their stability and forms in the timber panel 1 in addition to a closed back surface.
