Description

The present invention relates to a panel element, which is used in particular in the production of acoustically effective ceiling and wall surfaces. In particular, sound absorption can be achieved by means of such a panel element in order to make a room acoustics more pleasant, for example by reducing the reverberation.

The present invention has for its object to provide a panel element which is easy to manufacture and acoustically and aesthetically optimized.

This object is achieved according to the invention by a panel element comprising:

• an acoustic layer and a primer layer defined on the acoustic layer.

The primer layer is preferably fixed to the acoustic layer by means of an adhesive bond, in particular adhered directly to the acoustic layer.

In one embodiment of the invention it can be provided that the acoustic layer is formed from an elastically yielding material or comprises such an elastically yielding material.

It may be favorable if the acoustic layer comprises or is formed from a fiber material, in particular mineral wool, and / or a woven material.

The acoustic layer allows in particular due to a low sound reflection and due to the damped and / or oscillating storage of the primer layer an optimized sound absorption.

It may be favorable if the primer layer is formed from an open-pore material or comprises such an open-pored material.

In particular, it can be provided that the primer layer comprises or is formed from a foam material or a compressed and / or glued and / or pressed and / or sintered granules.

It can be advantageous if the primer layer comprises or is formed from expanded glass granules.

The primer layer is preferably arranged and arranged by means of the acoustic layer oscillating and / or damped on a substructure of a ceiling cladding or wall cladding.

The primer layer is preferably fixed to the acoustic layer by means of a plurality of adhesive dots and / or adhesive lines.

In particular, it can be provided that the primer layer is fixed to the acoustic layer by means of uniformly distributed adhesive dots and / or adhesive lines arranged in a regular pattern. This results in an optimized coupling of the primer layer with the acoustic layer. In particular, no chaotic distribution of splices is provided, which results, for example, from a large-area spraying of adhesive.

It may be favorable if the panel element is plate-shaped and has two main directions of extension, along which extend the acoustic layer and the primer layer with their respective largest expansions.

The acoustic layer preferably has a greater extent in one or both main directions of extension than the primer layer.

The acoustic layer and / or the primer layer are preferably in each case substantially parallelepiped-shaped and are stacked on one another and / or connected to one another in a normal direction running perpendicular to the two main directions of extent.

The acoustic layer and / or the primer layer preferably have exclusively cut and / or straight edges. In particular, no bevelled or rounded edges are provided. As a result, in particular the acoustic layers of several panel elements can be mounted practically without joints against one another.

The primer layer is preferably formed on one side, two-sided, three-sided or completely recessed along a peripheral edge region of the panel element with respect to the acoustic layer and / or arranged.

It may be favorable if the primer layer is set back by at least approximately 2 mm, in particular at least approximately 4 mm, for example approximately 5 mm, from the acoustic layer.

Alternatively or additionally, it can be provided that the primer layer by at most about 20 mm, in particular at most about 10 mm, is set back from the acoustic layer.

The acoustic layer is preferably directly on a substructure or an existing wall can be fixed, in particular festklebbar.

The panel element is preferably self-stabilizing. In particular, an additional stabilizing support plate for fixing the panel element is preferably dispensable.

The acoustic layer preferably has a material thickness (thickness) of at least about 10 mm, for example at least about 20 mm, preferably about 40 mm.

Alternatively or additionally, it may be provided that the material thickness (thickness) of the acoustic layer is at most approximately 150 mm, in particular at most approximately 100 mm, for example at most approximately 80 mm.

A material thickness of the primer layer is preferably at least about 4 mm, in particular at least about 8 mm, for example about 12 mm.

The terms "essentially" and "approximately" designate, in particular, deviations from the stated values of preferably at most 50%, in particular at most 20%, for example at most 5%.

The information given relates in particular to a prepared for mounting the panel element state thereof, which is in particular a state in the delivery of the panel element on a construction site.

The panel element is particularly suitable for the production of a panel system.

The present invention therefore also relates to a panel system which comprises a plurality of panel elements, in particular panel elements according to the invention.

The panel elements are preferably fixed next to each other and adjacent to each other relative to each other, so that the acoustic layers of the panel elements together form a substantially continuous acoustic layer of the panel system.

In particular, when the primer layers are recessed in circumferential edge regions of the panel elements relative to the respective acoustic layer, the panel elements with their respective acoustic layers can be pressed against one another laterally (on the narrow sides) and / or inserted into one another in order to form a gap between the panel elements in the area of the acoustic layer to avoid and thus obtain a continuous monolithic acoustic layer over the entire panel system.

The term "monolithic" is to be understood as meaning that the acoustic layer composed of several panel elements has acoustic properties and / or optical properties and / or flow properties, as if the entire acoustic layer of the entire panel system were made as a single element or from a single element Service.

Also, the primer layers of the panel elements, including the filler in the joints, preferably form a monolithic primer layer of the panel system which has acoustic and / or optical and / or flow characteristics as if the entire primer layer of the entire panel system, including the filler in the joints, were single Element or made from a single element.

In particular, when the acoustic layers of the panel elements are formed from a fiber material, it can be provided that the panel elements are fixed relative to one another such that fibers of an acoustic layer of a panel element on the one hand and fibers of an acoustic layer of a directly adjacent panel element on the other hand interlock, engage behind each other or otherwise connect together to ultimately produce a seamless and physically and optically uninterrupted acoustic layer of the panel system.

It can be advantageous if the panel elements are arranged adjacent to one another and adjacent to one another relative to one another, so that a joint, in particular a rectangular joint, is formed between the primer layers of the panel elements.

The joint is preferably filled with a filling material.

The filler material preferably corresponds at least approximately to the material of the primer layer, at least approximately in terms of its thermal expansion, its toughness, its elasticity, its permeability to air and / or its resistance to moisture in the finished state of the panel system.

In particular, a material for producing the primer layer, for example expanded glass granules, is used as the filler material.

The filler material preferably comprises a granulate which has a particle size distribution which at least approximately corresponds to the particle size distribution of a granulate of the primer layer.

It can be provided that the filling material and the primer layer comprise mutually different binders in order to connect the particles of the respective, in particular identical, granules with one another. In particular, this can on the one hand a simple and cost-effective production of the primer layer are made possible by a slow-curing and / or slow-drying binder is used, while preferably a binder of the filler is comparatively fast curing and / or fast drying to fast further processing after introduction to allow into the fugue.

In the cured and / or dried and / or ready-processed state, the filling material preferably has at least approximately the same throughflow properties as the priming layer. In this way, a different aging of the primer layer on the one hand and the filling material in the joint on the other hand can be avoided over time, which ultimately also ensures a long-term homogeneous and thus aesthetically pleasing surface. For example, different dust deposition rates and / or dust storage rates can be avoided.

The entire panel system preferably has, on the one hand, uniform flow characteristics over the entire acoustic layer on the one hand and, on the other hand, over the entire primer layer together with joint filling.

A substrate on which the panel system is fixed by means of the acoustic layer is preferably made airtight, for example as a finished filled and / or ground plasterboard wall or plasterboard ceiling.

The filling material arranged in the joint preferably supplements the primer layers of the panel elements to form a uniform and continuous, in particular uninterrupted and / or monolithic, priming layer of the panel system.

In particular, a uniform and continuous and uninterrupted surface is produced by means of the primer layer and the filling material arranged in the joints.

The filler material is reworked in particular by grinding, as soon as it has cured after the introduction into the joint.

On a side of the primer layer facing away from the acoustic layer, the primer layer is preferably provided with a cover layer, in particular a plaster layer or filler layer.

In particular, in this case a sound-transparent top coat can be provided.

The final coating is designed, for example, as an acoustic spray filler.

In particular, a two-layered design of the final coating can be provided.

The cover layer preferably serves for the optical covering of the panel elements to produce a uniform and aesthetically pleasing surface.

However, the cover layer is preferably acoustically effective at the same time as it is transparent to sound and thus incident on the cover layer sound through the cover layer and through the primer layer in the acoustic layer can be passed to be there effectively absorbed (at least partially and depending on the respective sound frequency).

The primer layer is preferably acoustically effective, in particular by absorbing large-scale vibrations and / or by sound absorption in pores of the primer layer.

The present invention further relates to a method for producing a panel element.

The invention is in this respect the task of providing a method by which an acoustically and aesthetically optimized panel element is easy to produce.

Identical or functionally equivalent elements are provided with the same reference numerals in all figures.

One in the 1 to 5 illustrated embodiment of a whole with 100 designated panel system is used in particular in wall and ceiling construction.

The panel system 100 is in particular an acoustically effective system, which can reduce a sound reflection in rooms and thus in particular an unpleasant reverberation.

The panel system 100 is mounted in particular on a (not shown) substructure or on existing walls or ceilings and forms after the completion of the same an aesthetically pleasing continuous and uniform surface.

The panel system 100 is in particular of several panel elements 102 produced.

Each panel element 102 is in particular plate-shaped and comprises an acoustic layer 104 on which a primer layer 106 is fixed.

The acoustic layer 104 is formed in particular of mineral wool. The primer layer 106 is formed in particular from expanded glass granules.

The primer layer 106 preferably forms a precoat layer on the acoustic layer 104 Finally, a cover layer (to be described later) for covering the panel elements 102 to be able to attach.

The primer layer 106 is in particular open-pored and sound-transparent.

As in particular the 1 to 3 it can be seen extending the panel elements 102 in two main directions of extension 108 ,

In particular, each panel element 102 formed substantially rectangular.

In a peripheral edge area 110 is the primer layer 106 preferably opposite the acoustic layer 104 set back. In particular, this is a circumferential return 112 educated.

The primer layer 106 is preferably by means of an adhesive bond 114 on the acoustic layer 104 established.

In particular, many adhesive dots 116 in a regular pattern and / or evenly distributed between the acoustic layer 104 and the primer layer 106 arranged to the primer layer 106 and the acoustic layer 104 to connect with each other.

In particular 3 it can be seen, are both the primer layer 106 taken alone as well as the acoustic layer 104 taken in each case substantially parallelepiped-shaped, wherein preferably no bevelled, bevelled, rounded or otherwise processed edges are provided.

Like that 4 and 5 can be seen, thereby an acoustic layer 104 a panel element 102 flat and just over the entire height to another acoustic layer 104 another panel element 102 be created. In particular, the adjoining acoustic layers 104 slightly, for example by at least about 1 mm, in particular at least about 3 mm, be pushed into each other to produce a physically and optically uninterrupted structure.

Thus, in particular, a continuous acoustic layer 104 of the panel system 100 available.

Due to the set-back order and / or configuration of the primer layers 106 the panel elements 102 results in a joint area between two panel elements 102 a fugue 118 ,

The joint 118 However, only results between the two primer layers 106 the adjacent panel elements 102 because the acoustic layers 104 the two panel elements 102 lie flat against each other.

In particular 5 it can be seen, is the fugue 118 in particular with a filling material 120 filled.

The filling material 120 can in particular with one from the joint 118 protruding excess 122 be applied.

This surplus 122 can after curing of the filling material 120 for example, be removed by grinding, ultimately a uniform, continuous and uninterrupted surface 124 all panel elements 102 to create.

The filling material 120 is preferably selected so that it has at least approximately the same properties in the cured state, in particular substantially identical flow properties, as the primer layer 106 ,

In this way, it can be avoided, in particular, that a locally varying accumulation and / or incorporation of impurities, in particular dust, results in the course of time. Ultimately, locally varying color changes can thus be avoided or at least reduced.

In addition, this can preferably be avoided by varying acoustic properties and / or stress cracks, etc.

Preferably, the filler material 120 as regards one or more or all of the constituents identical to a material for the production of the primer layer 106 , In particular, granules, for example expanded glass granules, are provided which are both part of the filling material 120 as well as a component of the material for the preparation of the primer layer 106 is used.

Also in 5 shown is a cover layer 126 pointing to the surface 124 the panel elements 102 after filling the joints 118 and the removal of the excess filler 120 is applied.

The cover layer 126 is in particular a sound-transparent plaster or spatula.

In particular, several cover layers 126 placed on top of each other to create an aesthetically pleasing and even visible side of the panel system 100 to obtain.

The panel elements 102 especially in the in the 1 to 3 shown prefabricated embodiment delivered to a construction site, then in particular in the composite, for example, semi-composite laid, in particular by sticking the acoustic layer 104 on a substructure or existing wall or ceiling.

Finally, the joints are still 118 filled, the excess filler 120 removed and one or more cover layers 126 applied.

Because of the primer layer 106 and preferably also the one or more cover layers 126 Sound-transparent formed, can on the finished panel system 100 incident sound to the acoustic layer 104 penetrate and thereby at least partially absorbed.

By using an adhesive bond 114 laying down the primer layer 106 on the acoustic layer 104 preferably results in a particularly simple production of the panel elements 102 ,

By the return 112 at the edge 110 In addition, a particularly uniform and appealing and at the same time acoustically highly effective wall or ceiling paneling can be provided in a simple manner.
