The task is also for the production of such an acoustic panel. is the preparation of a suitable method. Invention task claim 1 with an acoustic panel with characteristic features and will analyze it with a method with characteristic features.

Advantageous developments of the invention are given in the dependent claims. This the characteristic features described in between, on their own or in a particular from the summary and references in the claims in coinbination independently is essentially the subject of the invention. ceiling and/or wall Acoustic panel according to the invention, for use as coating an overlay arranged on an upper side and a lower side and upper side containing at least a portion of a wood-based plate with a layer of adhesive substance with a base plate and other acoustic panels for joining without, on long edges and/or cross edges corresponding locking profiles and the final sound. for absorption, an absorbent unit arranged on the bottom and an upper side base for transmitting the incoming room sound into the absorber unit. It has numerous recesses that penetrate completely into its plate.

Acoustic panel with corresponding locking profiles application, locking profiles, acoustic profiles without misalignment especially in a simple way, as it will ensure that surface of ceiling and wall coverings without any misalignment allows it to be produced. Direct wall or ceiling surfaces on uneven conditions or belonging to acoustic panels. Acoustic panels that can be seen in the space even on the fasteners There is no misalignment on the upper surface formed by Locking profiles In addition to this, it is ensured that the upper surface stays permanently without misalignment and that the positioning of the individual panels is permanently equal to each other, thus, for example, in the arrangement of the building. activities and/or 'Individual construction, such as wood-based plate coating formed by the climatic changes of the elements permanently preserved. From the slack From the concept of the panel it is understood that the upper surfaces are arranged in a plane. Acoustic panel in line with the invention, the individual method stages are the most since it is known, at least partially, from floor, wall and ceiling laminates. a particular design for the cost-effective acoustic panel. can be produced by the method. Another part of the acoustic panel in line with the invention 'Special advantage is that alternatively, in a known manner and in a wide variety of low cost production of floor, wall or ceiling laminate with corresponding recesses and an absorbent unit on the underside particularly cost-effectively, with the modification of the connection It can be processed into an acoustic panel in the direction of. Meet Particularly simple structural design of the acoustic part in the direction of so that each panel known as wall, ceiling and floor laminate allows simple and cost-effective modification of acoustic panels. overlays (claddings, coverings) visible through should be understood. These are either directly attached to the wall or ceiling. they can be attached or suspended ceilings or under ceilings, clip systems, as well as rail systems with mounting tabs. They can be arranged by means of fixing hardware and suitable joining elements. either directly on the wall or floor top surface in connection with must be understood or above the upper surface of the wall or ceiling or fixing stands, suspension equipment, attachments arranged in front of hardware, etc. The wood-based plate can in particular be a chipboard or fiberboard, for example an MDF or HDF plate or a plate bonded with mineral fiber it could be. In the meantime, depending on the intended use of the wooden panel, especially with low-formaldehyde or formaldehyde-free glue as a glued wood-based plate in accordance with the EN 717-1 norm. in the form of a formaldehyde stabilization of 0.03 ppm, preferably 5 to 0.02 S created by concentration. The wood used in this context based plate, especially with a formaldehyde-free binder, e.g. may have an isocyanate. Thus, in line with the invention The chipboard or fiber plates to be used preferably for the acoustic panel are the most It may at least contain a substantial amount of isocyanate binder.

Also wood-based plates e.g. It may contain other additives such as flame retardants or coloring agents. Divided from a base plate into several sections, the coating is made and not yet have a profile on its long and/or transverse edges An individual part of a wood-based plate is understood. Accordingly, the base plate of a chipboard or a fiberboard, eg. an MDF or HDF may contain the plate. A base plate can also be at least largely has the next panel length and panel width, and the top at least one coating layer, for example a decorative layer, has other layers of coating. Furthermore, the baseplate may also have an underlying coating consisting of one or more layers, for example a primer coating on the underside.

The base plate preferably has coatings between 4 mm and 12 mm, 'especially 8 mm ± 1 mm thick. In connection with the invention from a panel (eg acoustic panel) to each other at the wide edge and/or the longitudinal edge of the base plate A base plate with corresponding locking profiles is understood.

On right-angled base plates, that is, one short edge and one long edge on base plates with a transverse edge, two the one shorter than the edge is understandable. These can also be defined as forehead corners or capital edges. The interlocking profiles of the panel are the adhesive bonding of multiple panels. It was created to be combined without substance. by the way long each of the locking profiles arranged on the sides and the width each of the locking profiles arranged at the edges can be found in front of it and thus with a large number of acoustic panels. a completely flat (no protrusions) surface (wall or ceiling cladding) can be created. The transverse edge and the long edge are mutually the same may have a lockline profile. Acoustic panels of a surface can also all be created the same in size and shape. The veneer layer can be formed specifically as a decorative layer, as previously mentioned. Meanwhile, the decorative layer can be created in particular monochromatic or a a wood pattern can indicate a stone top, a tile pattern, or a fantasy pattern. Alternatively, a layer of tigeria can also be formed, for example as an abrasive layer. The veneer layer can also be multi-layered. For example, a base plate or a wood-based plate for the creation of the decor. may also contain coloring matter, so the base plate/wood base plate may have a primary color tone. In this respect the base plate/wood-based plate as part of a visible decor can be created. Stunningly painted base plate/wood Thanks to the base plate, especially the traditional significantly higher mechanical strength in painted floor panels colored primer, which is mandatory due to strains layers are not required. In this way, the production of the acoustic panel conventional top surface whose costs are known from the floor industry It is significantly lower than tigers. base plate/wood the coloring agents in the base plate, especially the painted surface. It can be used in tigers. Accordingly, the colorant With the help of materials, a colorful, especially decorative harmony of the recesses can be realized with ease. It can be created as a replica and has one or more layers. it could be. The cover may be arranged adjacent to the absorbent unit or the absorber may be merged into the unit. layer acting as anti-retraction For example, a decorative paper is used in the formation of the decorative layer. It may have anti-retraction paper. A directly printed On the panel, for example, a paint layer can be arranged to prevent being drawn into the decor layer. or opposite the covering layer of the panel/acoustic panel uncoated or coated according to its content (e.g. anti-shrinkage with a layer) the upper surface from the lower side is understood. For example, place bottom to prepare elements that can be seen from both sides in the distribution. The side may alternatively be covered with one or more covering layers, for example a decorative layer. A module in which sound waves propagate is understood. Absorber units 50 Between kg/m3 and 400 kg/m3, preferably between 50 kg/m3 and 300 kg/m3 and particularly preferably in the range of 100 kg/m3 to 380 kg/m3 It has a particularly low density and is formed with open pores.

Absorbent units consist of, for example, plastic materials. Thus, especially polyester fiber plates are suitable as absorbent units. With this alternatively, the absorbent unit may comprise a wooden material, for example a wooden one. may include the fiber insulation plate. Especially plastic as absorbent unit modified plates are suitable, such as plastic fibers It can be wood-based plates such as wood fiber plate or wood fiber insulation plate mixed with plastic particles. In line with the invention, the educational unit ranges from 250 kg/m3 to 380 kg/m3 with a density of up to 400 kg/m3 and As it creates a particularly high sound absorption rate, mineral plate, especially a polar laminated mineral plate contains. The absorber unit is specially formed in the form of a plate and is directly attached to the wood-based plate or veneer. The absorber unit is preferably l 1 mm ± 4, regardless of the material chosen. It has a thickness (plate height) of mm, where especially fleece absorbent consisting of laminated or non-laminated mineral plates the units have a thickness of 11 mm ± 1 mm. inside the base plate recesses can have different geometric shapes. eg round or they can be formed as angular holes and as slot holes.

Indents are adjacent to each other in the longitudinal and/or transverse direction of the panel. has been arranged. The recesses completely penetrate the base plate. they mean that the recesses are located next to the wood-based plate into its layers, i.e. both the coating layer or the upper applied on all layers as well as on the underside, i.e. They penetrate into the solid layers such as the preventive layer. Like this The indentations are on the upper side, where the sound waves crashing on the coating being guided through the recesses, hitting the absorbent unit, it is created to penetrate and diffuse into it. In addition, besides the recesses that penetrate into the base plate, wood-based coating from the veneer layer, especially in the edge areas of the panel protruding up to the inside of the plate and with it non-penetrating decorative recesses can be arranged. Decorative recesses a particularly high stability of the acoustic panel in the edge region and so that a large number of acoustic panels are bonded to each other. It ensures a particularly secure and permanent connection by means of non-locking profiles. The absorbent unit can be directly attached to the wood-based plate in the manufacture of the base plate, for example with the aid of an adhesive anti-shrinkage layer arranged on the underside. However, find a the bottom side (with the top surface of the wood-based plate or the bottom of the unit between the absorber unit (with the existing coating if necessary) An additional adhesive layer is arranged for bonding with the side.

This is in particular a hot melt (HotMelt), an adhesive foil or e.g. it can be a one-component adhesive such as white glue. penetration is foreseen. That is, the indentations of the adhesive layer they make a dent in it. In this way, sound absorption into the recesses penetrating sound waves 'especially easily penetrate the absorber unit. Since it can penetrate and not be reflected back from the adhesive layer, a marked improvement is achieved. In addition, according to a development of the invention, the recesses are inserted into the absorbent unit. It is envisaged to extend as far as the bottom of the panel. along and through an adhesive layer arranged as needed they protrude into the outer absorbent unit and thus the absorbent unit The indents are arranged in the same way. Meanwhile the indentations preferably they do not penetrate the unit. The indentations extending into the absorber unit once again significantly improve the sound absorption. Also, `Especially the recesses that penetrate the panel preferably and the entire length of the acoustic panel with decorative recesses where necessary It is envisaged to extend along the entire length of the panel, thus enabling an improved sound absorption of the sound hitting the panel. or diagonally to the longitudinal direction of the base plate, or oriented transversely to the longitudinal direction of the recesses reinforcement elements. Reinforcing elements e.g. strips It can be formed in the form of a stick. Reinforcement elements underside combined with, specifically glued, and e.g. penetrating the panel they provide increased strength of the panel in a large number of recesses. Reinforcement elements are specially adapted to the material of wood-based slabs and thus preferably of wood material such as chipboard, HDF or MDF they form. Reinforcement elements preferably spaced apart is arranged, where for example in the transverse edge region, especially the transverse Adjacent to the locking profiles at the edge, a reinforcing element is arranged, each oriented in the transverse direction of the panel. The reinforcement elements are preferably between 10 mm and 50 mm, in particular 20 mm ±2 mm wide. Reinforcement elements are absorbent in thickness. adapted to the thickness of the unit. For example pressing pressure or the base of the reinforcement element depending on the pressing method applied. The thickness of the reinforcement element in the pressing of the absorber unit equal to or up to 20% less than the thickness of the absorbent unit formed so that the bottom of the reinforcing element and the absorbent element It is ensured that it is pressed securely with the side. Especially 15mm For the creation of thin acoustic panels with a height of ± 5 mm the absorber unit appropriately to the height of the base plate. between 4 mm and 14 mm, especially 11 mm ±l mm created in height. Especially preferred sizes are high They provide an optimum ratio between stability, low production cost, minimum thickness and high density. In addition, the rates of particularly good sound absorption are approx. 12 between the base plate and the absorber unit. It is obtained in a height ratio of 1 :1. The absorber unit is preferably formed in one piece and is wood-based. the bottom of the plate as much as possible (if necessary, to the edge areas) up) completely. However, the reinforcement elements In an application on the side, the absorbent unit is particularly preferably a plurality of especially the absorbent arranged between the reinforcing elements has elements. In this way, the acoustic panel is at a sufficient height. A high sound tendency is provided in its durability. More of the absorber 4 mm to 14 mm depending on the height of the aforementioned base plate The optimum height between provides an optimum sound absorption and thus at a height of in particular 15 ± 5 mm, in particular 19 mm ± 1 mm. A thin acoustic panel can be prepared with The acoustic panel's fine structure, as mentioned above, acoustics in building planning in places where panels are not foreseen, then `important place It allows the possibility of later equipping with acoustic panels without losses. The veneer layer arranged on the upper side is a solid wood layer. can be formed, however, preferably the top of the wood-based plate made of PVC, PE, PP, polyester, As sheet of PU, as sheet material HPL, DPL, CPL, eg digital printing on foil, acrylic foil and/or top surface As a printed paint and/or resin layer has been created. The coating layer is additionally required for the application of the coating layer or a decorative layer, eg 13 adhesive layer, primer layer, spatula layers, etc. It may also contain auxiliary layers such as a corrugated layer and/or a structural layer or a structured The wear layer is the surface resistance of the acoustic panel against external effects. for improvement or visual evaluation of the surface and/or The tactile rendering of the top surface can be edited inside. Wear layer and/or each of the structural layer e.g. resin layer or coating It can be applied as a liquid or solid. Acinia layer and/or a digital printing method that creates a structural layer, especially a layer can be applied via eg. individual layers such as the structural layer it can only be applied locally, tactilely, for example, to create a negative or positive surface structure suitable for the decor. Profiles on the long sides and transverse sides are particularly preferred as locking profiles, ie for mutual locking has been created. By the way, profiles are 'especially rotatable profiles'. and/or swiveling profiles (later swivel swivel profiles) de) or as a vertical locking profile. Vertical from a locking profile, both sides of the acoustic panels to be joined profile in a vertical direction, for example, in the direction facing the top. a locking profile that can be nested in accordance with the fence profile understandable. Apart from that, vertical locking profiles to be joined (scissors-like) two profiles into each other and also (inside each other) locking profiles that can be folded in the direction showing an angle of 90° to the longitudinal axis of the profiles. Vertical locking14profiles are not particularly rotatable profiles or locking profiles that can be driven into each other in the plate plane. profile of the locking operation of the interlocking locking profiles. Locking profiles are understood to include a rotational movement and/or a translational movement around the longitudinal axis extending in the direction of It can be formed with or without a separate locking body. The profiles on the long sides and the transverse sides are preferably interconnected. they are opposite each other so that a first panel is joined by a transverse edge. can be locked on the long edge of a second panel. Profiles in this context It can be created as a rotating profile or a vertical profile.

Thus, in the application of rectangular panels, a large number of different tiling pattern (eg transverse edge adjacent to long edge) can be realized. Alternatively, corresponding interlocking with each of the transverse edges profiles, for example vertical lock profiles and with each of the long sides reciprocating locking profiles e.g. rotatable swivel It has profiles and thus, especially acoustic panels on the wall or It simplifies installation in ceiling areas considerably. preferably most At least at the transverse edges of the panels, the interlocking interlocking profiles, especially vertical locking profiles with a separate locking body are arranged. It does not consist of a separate locking body, eg base plate, absorbent unit or top surface coating, separate, which grips the profile area and locks the two acoustic panels together. a module is understood. Meanwhile the separate locking body is especially a height offset of the visible acoustic panel upper surface. and/or blocks a gap between acoustic panels. Vertical locking profiles can also be arranged on the long sides of acoustic panels Installation of acoustic panels directly on a wall or ceiling, for example It can be done with a sticky substance. However, acoustic panels preferably above or in front of the wall or ceiling regulated connection hardware Etc. mechanical joint on It is mounted via eleinani. For this, preferably the long side Fixing the acoustic panel in the area where the interlocking profiles are located. for the entry of connecting elements for mounting on the hardware equipment is arranged. Combining equipment in the acoustic panel matched with the element. For this, preferably on the long side the locking profile is at least partially modified and e.g. your profile merging with at least regional modification of its geometry created for inserting the element. alternative or as a complement a recess, for example a channel long-edge profile next to it, eg. in the profile base (channel base) region or arranged in a section at the bottom of the panel. joining element For example, it can also be adapted to the geometry of the locking profile and grasp this eg the side edge of a lower groove. The connecting elements can also be designed for a flexible mounting of ceiling and/or wall coverings. That is, the joining16 elements are in the same plane of the ceiling and/or wall covering. ceiling and/or wall covering vertical direction (perpendicular to the top surface of the acoustic panel) at least substantially immovably combined with the subfloor. joining elements so that the ceiling and/or wall covering is at least in a horizontal direction, preferably allows movement in both horizontal directions. In this way, eg. climate-related swelling and contraction of wood-based materials or tensions arising as a result of the movement of the subfloor ceiling and/or securely blocked in the wall covering. a flexible for flooring especially on or in front of a wall or ceiling an arranged rail system, moving on the rail system editable, both horizontally created as mounting elements It can be used in combination with a joining element that allows movement in any direction. Especially in a flexible flooring process, ceiling and wall coverings it is also tiled with a shadow space. ie wall and/or ceiling between the cladding and the wall, ceiling and/or floor that delimits each space is arranged to allow movement to the wall and/or ceiling covering. Further, the task of the invention is to supply water stages for the production of an acoustic panel. will be resolved with a method that has: a top side and a bottom side a wood-based plate, at least on the upper surface coating with a veneer layer, the wood-based plate, the base cutting the base plate to form the long and/or its transverse edges are profiled with locking profiles for non-adhesive bonding of multiple acoustic panels, an absorbent unit is attached to the underside, the base creation of recesses penetrating the inside of the floor plate to transmit the sound of the room that hits the top of the base plate into the absorber unit. particularly high sound absorption of a configurable acoustic panel It allows the production with the degree of Meanwhile, at least one many known from partial wall, ceiling or floor laminates method steps are used and thus the acoustic panel `Especially can be produced cost-effectively. Also, method '15 mm ±5 mm, especially 'Especially thinner acoustics' in the thickness range of 19 mm ± lmm It allows the production of panels 'especially with a high degree of sound absorption. and thus acoustic panels were not foreseen in the beginning. It is also possible to retrofit acoustic panels in constructions. is provided. Depending on the chosen sequence of the process steps, different application methods can be carried out. Advantageously Coating, cutting and profiling first method steps one after another and then merging and adding method steps are applied in a certain order. So first a wall, ceiling or floor laminate is produced (veneer, cut and profiled rendering) and then the end of the finished panel an acoustic panel by applying the unit and creating the recesses modification takes place. Meanwhile, the panel eg. become profiled After the process, it can be stored first and only if needed, it can be taken from the warehouse and processed into an acoustic panel.18 Besides the modification of the pre-existing panels, first coating, joining, cutting and profiling method steps and simultaneously with following or joining cutting or profiling can be applied to creating indentation. In this way, the known method A large-size wood-based It can be produced in a specially designed method for the production of acoustic panel acoustic panels. may consist of elements so that for the arrangement of the absorbent unit a large number of absorbent elements, with reinforcements if necessary, mounted can be done. Numerous additions, especially in conjunction with the coating method step can be applied. Thus 'Ex. a suitable withdrawal the barrier layer can be applied to the underside or other layers of coating It can be applied above or below the layer. Especially lining, acini and/or structural layers can be arranged. According to a development of the invention acoustic panels on the wall, ceiling or a suitable floor on the acoustic panel for fixing the acoustic panels a joint formed to fix it to the fixing hardware. a connector slot for inserting the element is arranged. The slot of the joint element is made of wood-based plate or may be built into the absorbent unit. However, the link Particularly secure panels in the element housing fixing hardware in particular the base plate or at least applied inside a reinforcement element. connector slot preferably simultaneously or without profiling or base It is applied before the creation of recesses penetrating the plate and thus a particularly efficient production is possible. The housing of the joint element19 is, for example, a panel extending in the longitudinal direction of the panel. created as a channel. By a joining element, for example localized by a mounting tab of a fastener. and/or a lower channel side edge to be partially gripped element can be created as a slot. The connector is for example a with the hardware of the wall, ceiling, stand, suspension system and/or other It can be connected with any kind of fixing hardware. joining element advantageously as a separate joining element, for example a It is created as a mounting element that can have a mounting tab. A first panel or a row of acoustic panels can be installed on an existing wall. or its arrangement on the ceiling is carried out with additional fixing elements.

These can be, for example, nails, bolts, nails and/or clips.

By means of nails and clips, nails or bolts, alternative or complementary to the acoustic panel without gaps or clamping mountable. Fixation created especially as a fence elements are advantageous. Fixing elements, especially acoustic panel showing a transition zone (wall-wall, wall-ceiling, wall-floor) can be edited in the edge region. That is, the fastening elements are especially acoustics of a first set of panels and/or a last set of panels It is used for fixing the panels for the first time. fastening elements In split top surface coatings, for example, new coating surface at the beginning and/or, for example, in recesses within the pavement surface can also be used. The fastening elements are a profile spring or a channel. For example, the upper channel side of the profile on the acoustic panel It can grasp under the edge. Fixing elements can also be formed to allow flexible laying of the wall covering20. Fixing elements are preferably mounted movably on a rail system such as joint elements. The last row of acoustic panels of a wall or ceiling covering cutting the acoustic panels from the long side depending on the size of the space i.e. by shortening in the transverse direction. final acoustic panel fixing the row of nails in the same way as mentioned above, with additional fixing elements such as bolts, nails and/or clips. Fixing the connecting elements to the acoustic panel is particularly simple. further combining according to a development of the invention to design on the long side of an acoustic panel of a mounting tab of the element in the outer region of a lower groove side edge of the locking profile regulation is foreseen. The assembly sequence, by the way, is especially Preferably, it grips the lower groove side edge of the locking profile on the long side, at least, circumferentially. according to a development of the invention to further improve the level of perpendicular to the acoustic panel top surface of the mounting benches without gaps regulation is foreseen. So the montage tab is at least at the bottom completely past the parts of the side edge of the channel or slightly It must grip tightly (without gap) so that the lower channel is sideways. edge eg. main body of fastener with mounting tab between, or, for example, in a wall or ceiling, or on a wall or clamped between the fixing hardware in the ceiling. In the meantime, the assembly bench is arranged on the acoustic panel without any other joining elements such as sticky substances, bolts, nails and the like21. Acoustic panels have locking profiles on their long sides.

They are made entirely of baseplate, cladding plate and/or can be formed from absorbent or, in addition to profiling, the base It may have a separate locking body on the plate. By the way locking profiles as vertical locking profiles on long sides can be created, however, especially rotatable, swiveling can be created as profiles and thus according to a development of the invention. a third acoustic panel with a first and/or a second acoustic panel can be combined with a twisting motion on the edge. long edge a separate locking body from the rotating profile and/or on its transverse edge. request consisting of a flipped profile with a vertical locking profile containing This inventive combination facilitates the installation of acoustic panels in ceiling and wall areas. If a panel in the first row of the panel comes loose, that will cause other acoustic panels to separate from the substrate. There is an increased risk for a domino effect. ceiling or wall coating to an undesirable loosening from the substrate. to be secured against It can be applied inside the adhesive-free locking profiles.

Adhesive application preferably locking on the long side takes place in the profile region. Sticky substance locking profiles It can be arranged between a first row of acoustic panels and a second row of acoustic panels in the area, thus providing a good safety against the falling of the wall or ceiling22 coating beforehand. wall and ceiling Increasing the fall safety of the cover, preferably on the long side of the locking profile on the second and third side of the acoustic panels with an additional application of adhesive substance in the area between the rows of it happens. In addition, to improve fall safety sticky substance intermittently every subsequent fourth, fifth and/or the sixth acoustic panel row, in the region of the relevant locking profiles. As an adhesive substance, especially the walls and/or walls such as liquid and glue. Adhesive substances that can be applied in the installation of the ceiling covering can be used. In addition to suitable adhesive materials in particular, e.g. component polyurethane, 2-component polyurethane, preferably joint filler Contains PVAC adhesive and/or phenol forinaldehyde. some aspects Although described in the context of a hardware, these aspects are the method they are understood to offer a recipe and thus a block eleinani or a module, a corresponding method, or should be understood as a characteristic feature of a method step.
