Description

The invention relates to a plate-shaped building element, in particular an acoustic panel, which has an open-pored, sound-absorbing carrier layer and a visible decorative layer.

Surface coverings made from panel-shaped building elements are available in different designs. Panel-shaped building elements in the form of acoustic panels are also common. These have different uses, the main purpose being to reduce noise. Acoustic panels can be used as wall cladding and ceiling cladding. In addition to reducing noise levels and improving acoustics, acoustic panels are also an elegant and modern furnishing element for a pleasant room atmosphere.

A plate-shaped building element in the form of an acoustic panel with an open-pored sound-absorbing carrier layer and a visible decorative layer made of wooden strips is known.

Through the EN 10 2013 010 091 B4 An acoustic element is known which has a large number of switching absorption channels.

Based on the prior art, the invention is based on the object of demonstrating a plate-shaped component which is optically and application-technically advantageous and has an efficient sound absorption capacity.

The solution to this problem consists in a plate-shaped component according to claim 1.

Advantageous embodiments and further developments of the plate-shaped component according to the invention are the subject of the dependent claims.

A panel-shaped component is in particular an acoustic panel that has an open-pored sound-absorbing carrier layer and a decorative layer on the visible side. Sound-absorbing means that the carrier layer is made of a material and/or has a structure that reduces sound energy, thus absorbing and absorbing sound. This is mainly done by converting the sound energy into another form of energy, such as heat or vibration energy.

According to the invention, the decorative layer is formed from decorative elements arranged at a distance from one another, the decorative elements being multi-layered and having at least one base layer and one visible layer. This embodiment according to the invention creates a plate-shaped component that is advantageous in terms of design and application technology and, in combination with the open-pored, sound-absorbing carrier layer, offers a purpose-optimized level of sound absorption or sound dampening. The sound absorption level or sound absorption capacity of a plate-shaped component according to the invention is high due to the structure according to the invention.

The decorative elements of the plate-shaped component are multi-layered, i.e. they have a multi-layer structure with at least one base layer and one visible layer.

In one embodiment, a decorative element is a laminate. Decorative elements can be made by dividing a large-format laminate board. Such a laminate board has a multi-layer structure and has a cover layer as the top layer. A decorative paper is arranged underneath, which forms the visually perceived surface. Below the decorative paper there is an underlay, usually a so-called kraft paper. Then comes the carrier board. This consists of an MDF board or an HDF board.

The above-mentioned layer structure of the laminate extends from the outside to the underside. The decorative elements can be created, for example, by separating the laminate board into decorative strips.

In one embodiment, the base layer of a decorative element is made of a wood material. In particular, the base layer of a decorative element consists of compressed wood fibers. The base layer can preferably consist of high or medium density wood fibers.

An embodiment that is particularly advantageous in practice provides that the base layer of a decorative element is formed or consists of a fleece or fleece material. The base layer is preferably formed by a polyester fleece (PET). In particular, the base layer of the decorative elements is formed from a polyester fleece if the carrier layer also consists of polyester fleece.

An advantageous aspect of the invention provides that the carrier layer and the base layer of the decorative elements are made of the same material, or at least of materials with comparable material properties. Such an embodiment is more pure and better for the environment, particularly with regard to recyclability.

In an embodiment that is particularly advantageous in practice, the base layer of the decorative elements is made of a fleece or fleece material. In particular, the base layer consists of a flexible, open-pored polyester fleece. The visible layer is applied, in particular glued, to the base layer. In this embodiment, the visible layer is preferably formed by a veneer or a veneer layer that is glued to the base layer using a suitable adhesive system, for example white glue.

The visible layer can be formed by a printed decorative layer, a decorative paper layer, a wood veneer layer, a leather layer, a cork layer, a textile fiber layer, a mineral fiber layer or a lacquer layer or can comprise one of the aforementioned layers.

A design that is interesting in practice, which also enables the panel-shaped components to have a striking appearance, is to form the visible side with a wood veneer layer made of real wood or a wood surface made of real wood. Preferably, wood surfaces made of oak or walnut are used, although these can have different surface structures and looks. For example, they can have stained or smoked surfaces. The visible layer can also have a painted or oiled wood surface. The wood veneer strips on the visible layer have striking appearances such as knots, filled cracks or similar optical defects such as resin inclusions. These looks increase the variety, the design options and the aesthetic aspects of the panel-shaped components, especially acoustic panels. In the case of acoustic panels, a visible side made of the natural material real wood in conjunction with the open-pored, sound-absorbing carrier layer and the structure of the multi-layer decorative elements has a beneficial effect on the acoustic performance of the panel-shaped components.

The aesthetics of the wooden surfaces with the natural play between smoothness, roughness, relief and grain come into their own extravagantly.

It is also possible that the surface of the visible side, especially if it is made of real wood, is weathered or pre-weathered. The aesthetics of the aging process can thus be used for special purposes.

Depending on the design of the visible layer and the structure, the visible layer can have a laminated surface structure.

Advantageous embodiments of the carrier layer provide that the carrier layer consists of a fleece or contains a fleece. According to the invention, the fleeces of the carrier layer are formed on the basis of polyethylene terephthalate (PET) and/or propylene (PP) and/or paper and/or natural fibers.

In the context of the invention, carrier layers based on natural fibers and/or polyethylene terephthalate (PET) fibers are considered particularly advantageous.

Natural fibers are fibers that come from natural sources such as plants, animals or minerals. A natural fiber that is advantageous for the purpose of the invention consists of sheep's fur or comparable animal fur or wool fibers.

The open-pored, sound-absorbing carrier layer can consist entirely or partially of porous materials, in particular with continuous pores from the front visible side to the rear side. The carrier layer can also consist of a foamed material, in particular a foamed biological foam material.

The carrier layer can be made up of several layers. The carrier layer can have a multi-layer structure made up of several layers of one material or several layers of different materials.

Another advantageous design with high practical application potential is that the visible side has a perforated, printed, embossed and/or brushed surface structure. This measure increases both the absorption capacity of the plate-shaped component for sound waves and their appearance. The plate-shaped component has positive optical effects with a high degree of sound absorption.

The structure of the visible side and its design in combination with the sound-absorbing carrier layer has a positive effect on sound insulation, sound reflection and reverberation reduction.

In addition to the carrier layer, the decorative layer can also be designed and intended to absorb sound. This can be achieved through the arrangement of the decorative elements of the decorative layer and the decorative elements themselves.

The plate-shaped building element or the acoustic panels have no or minimal smooth and closed surfaces, so that sound is not or only partially reflected and is broken down or absorbed in the absorber material.

The design and construction of the panel-shaped building element can improve the room aesthetics, the room climate, the room atmosphere and especially the room acoustics.

Another embodiment provides that the visible side of a decorative element includes an overlay. The overlay forms the outer transparent layer of the visible layer and protects it, for example, from environmental influences such as light radiation and/or moisture.

A measure to improve the application of the component provides for a joint cover to be provided at least on one side edge of the plate-shaped component. This is advantageous in terms of installation and also improves the appearance of a cladding formed from components according to the invention.

Decorative elements, in particular decorative strips, can be arranged at a distance from one another both along their long sides and at the head sides.

The decorative layer can have decorative elements of different sizes.

Decorative elements can be formed by the decorative strips. In particular, at least two decorative strips have a different length and/or width.

One measure to improve practical use is for the carrier layer to have a stabilizing layer. The stabilizing layer can be a fleece, mesh or fabric layer. The stabilizing layer can be embedded in the carrier layer. Embedded means that the stabilizing layer is surrounded on both sides by the material of the carrier layer.

The stabilization layer can also be provided on an outside of the carrier layer. For example, the stabilization layer can be arranged on the back of the carrier layer. The stabilization layer forms a backing layer that is advantageous both for stabilization and as a vapor barrier or for laying the building element.

The plate-shaped building elements are designed and intended to be mounted on a substructure, for example on wooden battens.

A further advantageous embodiment provides that the plate-shaped components can be mounted on or onto a surface using a Velcro connection. The Velcro connection can comprise or be formed by Velcro connecting elements such as Velcro tape or Velcro pads. The plate-shaped components or their carrier layer preferably have a fleece backing or a backing with a hook, loop and/or fleece layer. A backing made of velour or felt is also well suited for the intended purpose. Velcro tape or Velcro connecting elements are then attached to the surface to be covered. Velcro connecting elements can be glued to a surface, for example a wall or a ceiling. The plate-shaped components can then be pressed and fixed with the backing onto the Velcro tape or Velcro connecting elements. The hook, loop and/or fleece layer on the back of the carrier layer engages with the hook of the Velcro tape or Velcro connecting elements. This creates a resilient but reversible Velcro connection between the plate-shaped components on the surface.

The back of the carrier layer of a plate-shaped component forms one joining partner of a Velcro connection. The second joining partner is formed by Velcro connecting elements. The Velcro connecting elements are attached to a surface to be covered and form one joining partner of the Velcro connection. The back of the carrier layer forms the first joining partner of the Velcro connection and is designed and intended to form a Velcro connection with the Velcro connecting elements.

A design that is advantageous in terms of room climate as well as hygiene and health provides that the carrier layer consists entirely or at least partially of materials with pollutant-reducing or pollutant-absorbing properties.

In addition to sound-absorbing properties, the carrier layer can also have pollutant-absorbing properties or can be made entirely or partially from a pollutant-absorbing material. In particular, this measure can bind and absorb or reduce pollutants from the room environment. In particular, the measure can help reduce formaldehyde and similar pollutants or environmental toxins in the room air.

Corresponding parts and components are available in all 1 to 9 provided with the same reference symbols.

In the 1 and 2 In each case, a plate-shaped component is shown in the form of an acoustic panel 1. The acoustic panel 1 has an open-pored, sound-absorbing carrier layer 2 and a decorative layer 3 on the visible side. The decorative layer 3 is formed from decorative elements 4 arranged at a distance a from one another.

The carrier layer 2 is made of an open-pored, in particular porous, sound-absorbing material or contains such a material. The carrier layer 2 can consist of a fleece or contain a fleece, wherein the fleece is formed on the basis of polyethylene phthalate (PET) and/or propylene (PP) and/or paper fibers and/or natural fibers.

The carrier layer 2 as shown in the 3 has a layer 5 made of an open-pored sound-absorbing material, wherein the layer 5 is formed from a fiber mixture, in particular from a fiber mixture of natural fibers, for example sheep's wool fibers and polyethylene phthalate (PET) fibers.

In the case of acoustic panel 1, which is described in 4 a section is shown, the carrier layer 2 comprises two layers 6, 7 arranged on top of one another, the upper first layer 6 facing the visible side 8 being made of natural fibers and the lower second layer 7 on the rear being made of polyethylene phthalate (PET) fibers or wood fibers. The lower layer 7 of the carrier layer 2 can be a perforated wood fiber board.

A further structure of a carrier layer 2 is shown in the illustration of 5 . There, the carrier layer has a first layer 6 and a second layer 7, with a stabilizing layer 10 being provided on the back 9 of the second layer 7 of the carrier layer 2. The stabilizing layer 10 can be formed by a fleece, mesh or fabric layer or can be implemented by a coating, with the stabilizing layer 10 preferably being open-pored.

The first layer 6 and the second layer 7 of the carrier layer 2 consist of or contain a fleece, wherein the fleece is formed on the basis of polyethylene phthalate (PET) and/or propylene (PP) and/or paper and/or natural fibers.

The decorative layer 3 of the acoustic panel 1 is available in all 1 to 9 The multi-layer structure of the decorative layer 3 has a base layer 11 and a visible layer 12. This is illustrated by the detailed views of the 3 to 5 .

The base layer 11 is made of a wood material, in particular of compacted wood fibers.

An alternative embodiment provides that the base layer 11 is formed or consists of a fleece, in particular of a polyester fleece.

The visible layer 12 can comprise a printed decorative layer, i.e. a printed decoration, a decorative paper layer, a wood veneer layer, a leather layer, a cork layer, a textile fiber layer, a mineral fiber layer or a lacquer layer.

The visible layer 12 forms the outer visible layer of a decorative element 4. The side edges 13 of a decorative element can be sawn rough. In particular, the side edges 13 of the decorative element 4 are open-pored.

The visible layer 12 can have a perforated, printed, embossed and/or brushed surface structure. The visible layer 12 can also comprise an overlay as an outer layer, which ches represents a transparent protective coating.

In the representations of the 1 and 2 and 3 to 5, the decorative elements 4 of the visible layer 12 are formed by decorative strips. These extend over the length of the plate-shaped component or the acoustic panel 1.

Along their longitudinal edges 14, adjacent decorative elements 4 have a distance a. The distance a is the same in the illustrated embodiments. The distance a between individual decorative elements 4 can, however, also be different from one another.

The 6 and 7 show acoustic panels 1 or a section of an acoustic panel 1 in an installation situation. It can be seen that the acoustic panels 1 are mounted on a substructure 15, for example a wooden batten. The substructure 15 ensures rear ventilation and contributes to improving sound absorption.

Not shown, but advantageous for assembly, is also the fastening of the acoustic panels 1 to a surface using a Velcro connection, in particular using Velcro tape or Velcro fasteners. The back of the open-pored, sound-absorbing carrier layer 2 has a hook, loop and/or fleece layer, for example made of velour, felt, fleece or a woven layer. The Velcro tapes or Velcro fasteners are fixed to the surface and the acoustic panels 1 are pressed with the back against the Velcro fasteners. This creates a resilient but reversible mounting system for the acoustic panels 1.

For acoustic panel 1, as shown in the 7 As can be seen, the carrier layer 2 comprises three layers 16, 17, 18. A first layer 16, on which the decorative layer 3 is arranged, consists of natural fibers, in particular sheep's wool fibers. A second middle layer 17 of the carrier layer 2 consists of polyethylene phthalate (PET) fibers or also of a foamed natural material or an open-cell acoustic foam. A third rear layer 18 of the carrier layer 2 consists of a compacted wood fiber material, which is provided in particular with perforations or microperforations, wherein the perforations have continuous holes, i.e. extending over the entire thickness of the layer 18, and/or slits and/or recesses, slits or channels partially penetrating the thickness of the layer 18.

For the acoustic panel 1 as shown in 8th The decorative layer 3 is multi-layered. Here too, the decorative layer 3 has a 8th base layer (not shown) and a visible layer.

The decorative layer 3 is formed from decorative elements 4, wherein the decorative elements 4 are designed as decorative strips. The decorative strips can be formed entirely or partially by rods which are positioned in the longitudinal direction of a decorative element 4, joint 19 to joint 19, or are arranged between the head-side joints 19 at a distance a1. The decorative elements 4 or the decorative strips can have a different length and/or width from one another.

Based on 9a and 9b it can be seen that an acoustic panel 1 has a butt overlap 21 on an outer side edge 20. The butt overlap 21 extends over the length of the acoustic panel 1 along its long side. The butt overlap 21 is formed by a lateral projection 22 of the decorative element 4 extending above and along the side edge 20. The decorative element 4 protrudes laterally by approximately 30% of its width compared to the longitudinal edge of the carrier layer 2 located underneath.
