Description

The invention relates to a wall structure according to the preamble of patent claim 1 and a method for assembling such a wall structure according to patent claim 13.

According to DIN regulations 58125 and 18032, all walls of sports halls must be flat and force-relieving. So-called impact walls are installed for this purpose. Area-elastic impact walls, which consist of a metal or wooden structure, and point-elastic impact walls are known. Such point-elastic baffle walls are for example from DE 102 57 367 A1 , of the G 86 34 785 and the GM 76 38 003 known. In all of these solutions, a top layer made of a textile material or a plastic material is applied to an elastic plastic layer, for example a foam.

In the case of area-elastic impact walls, such as those from the DE 100 42 565 A1 or the DE 298 15 801 U1 are known, a top layer with a damping layer and a visible surface, which in turn can again be formed by wood panels, are applied to a slat-shaped substructure.

The assembly of such baffle wall constructions is very complex, since first the substructure from the slat construction and then the various layers (damping layer, visible surface, etc.) have to be formed.

Another disadvantage of conventional solutions, in particular area-elastic impact walls, is that, due to their complex structure, they have a considerable structural height of at least 60 mm.

From the pamphlet DE 70 43 552 U a wall construction is known which has a plurality of wall panels, each with an insulating layer or damping layer. This has a top layer made of a wood or wood substitute. For the mutual connection of the wall panels with each other are in the damping layer - on their side surfaces - Grooves formed that assign to one another for adjacent wall panels. In the assembled state, the position of the wall panels in relation to one another is defined by a tongue inserted into the groove. The disadvantage of this solution is that a relative position of adjacent wall panels is not reliable due to the material properties of the damping layer.

From the JP H11 131622 A a sound-absorbing wooden construction panel is known, a sound-absorbing layer being glued under a wooden layer.

The WO 2007/085260 A1 discloses a sandwich element with a core made of mineral wool and a steel plate attached to it at least on one side.

In the FR 2 832 470 A1 a lamellar profile is shown, which consists of a front, a connecting piece and a rear. A connecting element connects several of these slat profiles with one another.

The pamphlet EP 0 069 698 A2 shows a wall construction with wall panels that are individually mounted to a wall surface using screws. The problem here is that a position of the individual wall panels relative to one another, in particular a uniform flat level on the visible side, can only be defined with a great deal of effort via the screw-in depth of the screws.

The pamphlet DE 37 39 313 A1 shows a wood-based panel with a cover layer as a sound-absorbing wall or ceiling cladding with a simple structure. The relative position of individual wall panels to one another is not discussed here.

In contrast, the invention is based on the object of creating a wall construction that can be assembled from a plurality of wall panels, in particular a baffle wall construction which, with a simple construction of the wall panels, enables them to be installed in the correct position with little effort. Accordingly, it is also an object of the invention to provide an assembly method for such wall constructions.

With regard to the wall construction, this object is achieved by the features of claim 1 and with regard to the method by the features of the independent claim 13.

Advantageous further developments of the invention are the subject of the dependent claims.

According to the invention, the wall construction, for example a baffle wall construction intended for a sports facility, for example a sports hall or a wall construction to improve the acoustics or some other wall construction, has a plurality of wall panels each with a damping / insulating layer that directly or indirectly carries a top layer. The invention is generally not limited to the application mentioned, but relates generally to wall coverings in which wall panels are designed with a top layer and a damping layer. In particular, fastening means for fastening to a wall, for example a wall of a sports facility or a wall of a concert / lecture hall, can be assigned to these wall panels, or at least a subset of them. As a fastening means, the wall construction can include, for example, an assembly bond, a suspension or a screw connection, nailing or the like. In particular, the wall panels can be prefabricated as a sandwich construction having at least the two mentioned layers. This means that they can be laid in a simple manner immediately after delivery on site. The top layer has at least one layer, in particular one made of wood or wood substitute materials, which is already connected to the damping / insulating layer at the factory. In particular, the top layer is made harder and / or tougher than the damping / insulating layer. The wall panels can be fastened to the wall in particular via the fastening means, by gluing or in some other way, such as for example by hanging, screwing, nailing, stapling, etc. For the relative positioning of the wall panels to one another, tongue and groove-like connecting means are provided on at least one side surface of the respective panels, which cooperate in such a way that adjacent wall panels can be positioned, in particular positioned, on one another in a direction perpendicular to a large area of the wall panels. According to the invention, the tongue-like connection means are provided on the top layer.

This results in a force transmission between adjacent wall panels via the, compared to the insulating layer, harder and / or tougher top layer by means of the tongue / groove-like connecting means. The positioning of the wall panels with respect to one another is more precise due to the greater hardness and / or toughness of the top layer and has a higher stability compared to solutions in which the tongue / groove-like connecting means are provided on the side surface of the damping layer. Another advantage is that the top layer, compared to the damping layer, is arranged further outwards in relation to the wall to be covered and so the groove is more accessible during assembly for the attachment of an external tongue, and that the wall panels are in principle also angled at a steeper angle during installation can. In this way, a simpler and more permanent flat laying of the wall panels is possible.

The fact that the grooves are arranged in the harder and / or tougher top layer also enables a smaller number of fasteners to be used, since the wall construction is or can be designed to be self-supporting to a greater extent due to the thus harder or tougher grooves.

In a further development, a subset of the wall panels is therefore fastened by means of the tongue-and-groove-like connecting means of adjacent wall panels, that is to say without additional fastening means.

In principle, the sandwich-like structure of a softer damping layer and a harder top layer advantageously combines the properties of point elasticity (soft layer) and surface elasticity (hard layer) mentioned in the introduction.

According to the invention, the tongue-and-groove connection is formed in a conventional manner by grooves and an external spring. A foreign spring is a separately insertable or inserted spring in the sense of a spring that can be detached from the grooves. It is inserted into mutually aligned grooves on adjacent side edges / side surfaces of the top layers of the wall panels. Alternatively, the tongue can be formed by a tongue profile which is formed on one of the wall panels and engages in a groove of an adjacent wall panel. In both cases, the tongue / groove-like connection can also be designed with a lock in the manner of a clip or a click connection, as is used, for example, in floor panels.

The tongue profile or the external tongue can be used as an optical design element if the wall panels are laid with or without spacing. Depending on the development, the distance can be set via a ratio of a depth of the external tongue to a sum of the depths of the receiving grooves or via a ratio of a depth of the tongue profile to a depth of the receiving groove.

If an invisible joint is to remain between the wall panels, i.e. the top layers are butted against one another, in a further development the depth of the external tongue is equal to or less than the sum of the depths of the grooves or the depth of the tongue profile is equal to or less than the depth of the receiving grooves Groove.

According to the invention, a sum of the depths of the grooves in which the external spring engages is smaller than a depth of the external spring itself. Thus, the grooves cannot completely accommodate the external spring and a central spring section remains visible from the outside.

In the solution in which the tongue is formed by a tongue profile formed on a wall panel, this can occur when the depth of the groove is less than the depth of the tongue profile formed on the wall panel, which engages in this groove.

In a further development, a groove base of a respective groove extends in the circumferential direction of the top layer.

In a further development, adjacent wall panels have an offset of their upper layers relative to one another in the direction perpendicular to the large area. The resulting surface of the wall construction is then stepped in appearance. This can be useful, for example, to improve the acoustics of the wall construction or to influence the appearance. In order to achieve this, in this development, for example, the positions of mutually adjacent grooves, based on the direction perpendicular to the large area, are unequal in their respective top layer. The connection via the tongue / groove-like connection means leads to a stepped offset in the sense of projecting or receding wall panels. It is advantageous if the thicknesses of the respective damping layers of the wall panels are adapted so that this offset is compensated for at the rear (wall side), i.e. the damping layers can be brought into contact with the wall or another substrate or are in contact.

In another further development, or in addition, adjacent wall panels have a flush transition of the visible sides of their upper layers in relation to the direction perpendicular to the large area. So they are essentially smooth, flat, arranged in this direction without any offset to one another. In particular, as explained at the beginning, this is necessary in the case of impact protection walls in the sports field, since no edges that are prone to injury must protrude here. In order to achieve this, positions are included in this training of adjacent grooves, based on the direction perpendicular to the large area, are the same in their respective top layer.

In a further development, at least one of the foreign springs is matched to at least one of the grooves with which it forms the tongue / groove-like connecting means with a press fit. For example, a durable pre-assembly of the foreign spring in the relevant groove can be implemented in a simple manner. In addition, the assembly of the wall panel configured in this way is made easier, since the external tongue cannot fall out of the groove.

The assembly or laying is even easier if at least one of the foreign springs can be deformed in a flexurally elastic manner in a direction transverse or perpendicular to the large area. This also improves the elasticity of the wall construction, especially in the case of the impact protection wall.

In general, the wall construction according to the invention enables faster and easier assembly of the wall panels in comparison to conventional wall constructions by means of the tongue and groove-like connecting means. Furthermore, the wall construction according to the invention can be designed with a significantly lower structural height than conventional solutions, so that it can be installed without problems, especially when renovating halls or rooms that are designed, for example, with a point-elastic baffle wall or even without a baffle wall.

As explained at the beginning, the wall construction according to the invention is not limited to an application in impact walls, but can be used in general for wall cladding in which a high-quality insulating / damping cladding is required. The wall construction can also be designed with a view to optimizing the acoustics and thus serve to cover auditoriums, concert halls or the like. In principle, it is also conceivable to design the wall construction as a design element due to its high-quality structure with an insulating layer / damping layer and top layer. Accordingly, the damping / insulating layer is either with regard to optimal mechanical damping (impact wall) or with regard to optimal acoustics (noise insulation) or also designed with a view to optimal insulation (thermal insulation) or an optimal appearance.

The wall construction according to the invention in its further development with flush transitions of the visible sides of the upper layers of the wall panels is moreover characterized by an attractive appearance due to the flat upper layer with the low construction height. This structure also enables much simpler cleaning and care compared to conventional wall constructions, in particular impact wall constructions.

In a particularly preferred embodiment, the top layer has a multilayer structure. This can for example be made of plywood.

In order to have a positive influence on the manufacture and relocability of the wall panels, the groove or the grooves in a further development extend predominantly in a softer one of the layers of the multilayer structure.

In a development, at least one groove flank is formed by a harder layer of the multilayer structure that delimits the softer layer.

The opposite solution, in that the groove or grooves predominantly extend or extend in a harder one of the layers of the multilayer structure, is also possible. Then, in a further development, at least one groove flank is formed by a softer layer of the multilayer structure that delimits the harder layer.

The damping / insulating layer preferably consists of a foam. A PUR foam or the like has proven to be particularly suitable for impact wall constructions. In the case in which the wall construction is optimized with regard to the acoustics, the damping / insulation layer can be optimized accordingly for sound insulation or other properties that are important for a concert hall.

In one development, a damping capacity of the damping layer is influenced by the damping layer protruding laterally beyond the top layer. At the The wall panels can thus be laid with their damping layers in contact and with pre-tensioning.

To improve the visual appearance, the upper layer can have a decorative layer. Such a decorative layer can consist, for example, of a film, a CP laminate material, a real wood veneer or a textile or leather layer.

In a preferred embodiment, the top layer preferably has a wall thickness in the range from 6 to 12 mm and the insulating / damping layer is then approximately in the range from 5 to 15 mm.

In one exemplary embodiment of the invention, a pre-fixing and / or a final fastening of the wall construction is formed via an adhesive layer of the impact wall panels. Such an adhesive layer can for example have a multiplicity of adhesive strips, which can be formed by a double-sided adhesive tape or adhesive cords. This adhesive layer is provided at the factory on the sandwich structure and covered, for example, by a protective paper or the like, which is then removed for gluing.

As an alternative to using the adhesive layer, a Velcro connection can be provided.

Of course, pre-fixing can be dispensed with in the case of adhesive systems with sufficient initial adhesion or when using other fastening means.

In an alternative embodiment, a carrier plate is provided which carries the damping / insulating layer and the top layer. This carrier plate can in turn be made of multiple layers, in particular made of a wood or wood substitute.

In one embodiment, this carrier layer is made thinner, in particular somewhat thinner, than the top layer.

For example, the already mentioned, in particular mechanical fastening means for fastening to the wall can be provided on the carrier plate. As an alternative or in addition, however, the above-mentioned adhesive strips can also be provided for pre-fixing on the carrier plate.

According to a method according to the invention, the wall panels are delivered to the construction site. In particular, they can already have the sandwich structure, so that the damping layer is already firmly connected to the top layer. Optionally, they can be pre-fixed by means of the adhesive layer or some other suitable means. According to the invention, the wall panels are laid by connecting the tongue and groove-like connecting means arranged on the side surfaces of adjacent top layers, so that the wall panels are positioned against one another at least in the direction perpendicular to the large surface.

A permanent attachment to the wall can take place by means of an assembly adhesive or some other attachment, for example screwing, nailing or the like. Instead of the assembly gluing, the fastening can take place via a Velcro connection, for example several strip-shaped Velcro connectors, which are attached to the wall and panel side.

As mentioned, pre-fixing can be dispensed with if the mounting adhesive has sufficient initial adhesion.

Preferred embodiments of the invention are explained in more detail below with reference to schematic drawings. Show it:

• Figure 1 a highly schematic representation of a hall end wall provided with a wall construction;
• Figure 2 a section through a first embodiment of a wall panel of a wall construction according to Figure 1 ;
• Figures 3 and 4th a section through a second and a third exemplary embodiment of a wall panel, and
• Figures 5 to 7 three further exemplary embodiments of wall panels with tongue and groove-like connecting means (foreign spring).

The invention is explained in the following first with the aid of a wall construction for a sports hall or the like and then with the aid of acoustically optimized wall constructions. As already stated at the outset, the invention is not limited to such applications, however, since the wall panels according to the invention can also be used to clad the walls of lecture halls, concert halls or the like or as a design element or the like.

Figure 1 shows a schematic representation of the front of a sports hall 1, which must be provided with a wall structure 2 in accordance with the DIN standards mentioned above. According to the invention, this wall construction 2 consists of a plurality of wall panels 4 which are glued, screwed, nailed or otherwise fastened to the wall, in the present case an end wall 6.

In contrast to conventional solutions, the wall construction with the substructure and the insulating elements attached to it is not manufactured on site, on the construction site, but the wall panels according to the invention are prefabricated components that only need to be attached to the wall 6.

Figure 2 shows a section along the line AA in Figure 1 a first embodiment of a wall panel 4 for a wall construction 2 according to Figure 1 . This prefabricated wall panel 4 has a top layer 8 made of 6-12 mm thick plywood, which, as indicated by dashed lines, can also be provided with a decorative layer 10, which is made, for example, of a film, a real wood veneer or a CPL material (Continuous Pressure Laminate) may exist, which is applied to the top layer 8 at the factory. On the wall side, this top layer 8 is connected to a damping layer 12. This damping layer can for example consist of a suitable foam, for example PUR foam or the like. The fat the damping layer 12 in the illustrated embodiment is approximately 8 to 15 mm.

As further in Figure 2 is indicated, an adhesive layer is applied to the large surface of the damping layer 12 facing away from the top layer 8, which adhesive layer is continuous or, as in the illustrated embodiment, is formed by a plurality of spaced apart adhesive strips 14. These can be formed, for example, by double-sided adhesive tape or adhesive cords that are applied at the factory. These adhesive strips 14 are covered with a peelable paper or the like in order to avoid accidental sticking.

Instead of the adhesive strips 14, a Velcro connection can also be provided, one part of which is attached to the wall 16 and the other part, which is to be brought into operative engagement, remains on the panel. The wall-side Velcro part (strip) can be provided with an adhesive layer so that it adheres to the wall when the panel is attached. Instead of a strip-shaped Velcro connection, a flat Velcro connection or the like can also be used.

As explained at the beginning, the wall construction 2 according to the invention is characterized by a very low structural height H (see Figure 2 ) out. With the wall construction according to the invention, this structural height H begins approximately in the region of 16 mm, while conventional area-elastic walls begin approximately at an structural height H of 60 mm, these walls being provided for the run-off zones of the playing fields. In other words, the construction according to the invention allows the structural height to be reduced by more than half in many cases.

This delivered sandwich structure, consisting essentially of the top layer 8, the damping layer 12 and the adhesive strips 14 and possibly a decorative layer 10, is provided as a prefabricated panel at the factory. The wall panel 4 can then be pre-fixed to the wall 6 on site by means of the adhesive strips 14 or the Velcro connection. A final fixation, which does not require the pre-fixation step, takes place at the in Figure 2 illustrated embodiment via an indicated assembly bond 18, which is either applied on site or is also already provided as an adhesive strip or the like on the wall panel 4. It is preferred to apply this assembly bonding only on the construction site for permanent bonding. The assembly effort can be significantly reduced by the pre-fixing by means of the adhesive strips 14.

Alternatively, as already mentioned, pre-fixing can be dispensed with when using assembly bonding with sufficient initial adhesion.

As an alternative to the assembly gluing, the fastening can also take place in a conventional manner by screwing, nailing or other means.

Figure 3 shows a variant of a wall panel 4 in which the top layer 8 and the damping layer 12 and possibly the decorative layer 10 are designed in the same way as in the embodiment described above, so that reference can be made to the previous statements in this regard.

In this exemplary embodiment, the top layer 8 and the damping layer 12 are applied to a carrier plate 20 which can consist of plywood or another suitable material. In other words, in this exemplary embodiment, the sandwich construction consists of three basic elements: the top layer 8, the damping layer 12 and the carrier plate 20. For fastening, this can be provided with suitable fastening elements, for example a rear suspension 22, which is then inserted into corresponding receptacles on the Wall 6 is hung. In principle, the sandwich structure can according to Figure 3 also similar to the embodiment 2 first pre-fixed via adhesive strips 14 or a Velcro connection and then permanently fixed via the assembly adhesive 18.

To improve the relative positioning, the wall panels 4 of all exemplary embodiments are explicitly only in the Figures 4 to 7 - executed with tongue / groove-like connecting means in the form of profiles, which are provided on the upper layers 8, so that the relative positioning perpendicular to the large area of the wall panels is improved. The embodiments of Figures 1 to 3 have such tongue and groove-like connecting means, but they are not shown because they are based on Figures 2 and 3 initially only the sandwich structure should be shown.

The illustrations in Figures 4 and 5 only the top layer 8 made of a wood-based material, for example a plywood, is shown, the decorative layer 10 and the insulating layer 12 and the adhesive strips / assembly bonding 14, 18 are each only indicated by dashed lines. It can also be a suspension 22 according to Figure 3 be provided.

In the embodiment according to Figure 4 grooves 26 are formed on side surfaces 24 of top layer 8. Corresponding springs 30 are then formed on opposite side surfaces 28, which during assembly - as in FIG Figure 4 shown - immerse in the opposite groove 26 of the top layer 8 of the adjacent wall panel 4 '.

Corresponding tongue and groove profiles are also formed on the side surfaces / front edges running parallel to the plane of the drawing. In this way, an overlapping of the wall panels 4, 4 'can be reliably avoided, so that the risk of injury to the athletes is reduced.

At the in Figure 5 The variant shown, grooves 26 are formed on the side surfaces 24, 28, which are aligned in the assembled state and into which foreign springs 32 are inserted when the wall structure 2 is assembled in order to fix the wall panels 4, 4 'perpendicular to their large surface or assembly plane relative to one another.

As mentioned at the beginning, the tongue and groove elements can be designed with click connections similar to the floor panels, which lock in the assembly plane or plane of the large area, so that gaps are prevented from forming, for example due to temperature changes.

As in the Figures 4 and 5 indicated, the wall panels 4, 4 ′ can each be provided with a decorative surface, for example a decorative layer 10. This decorative layer can be formed by a film, by a CPL material, real wood veneer or the like.

The thickness D of the top layer or barrier layer 8 can for example be between 6 and 12 mm. As mentioned, the use of plywood for the top layer 8 is preferred. Of course, other materials can also be used. The grooves 26 in the side faces / end faces of the wall panels 4, 4 'are preferably formed by milling or the like. The same applies to the spring profiles 30 of the exemplary embodiment according to FIG Figure 4 , which are formed in one piece with a respective top layer 8. In principle, however, it is also conceivable to form the tongue and groove profiles by elements attached to the top layer 8 and firmly connected to it.

In the case in which the wall construction is used to cover a concert hall or the like, the wall panels can be provided with perforations and / or slots which are designed with a view to improving the acoustics. It is quite conceivable that the wall construction will be used in multi-purpose halls, where it serves both as a baffle wall and as an acoustic wall. In other words, in this case the construction is designed both with regard to mechanical damping / insulation and with regard to acoustics.

Show embodiments for the acoustically advantageous cladding of a concert hall Figure 6 and 7th . According to Figure 6 the wall panels 4 have the mentioned perforations 34, which penetrate the respective top layer 8 of the wall panels 4 and specifically influence the acoustics. The panels 4 'are free of these perforations, so that their top layer 8' is compactly closed.

On closer inspection, in Figure 6 it can be seen that the foreign spring 32 - compared with that according to FIG Figure 5 - Is designed lower or flatter. Because of its plastic material and the flat design, it is designed to be flexible in the direction perpendicular to the large area of the wall panels 4, 4 '. It is inserted into the individual grooves 26. According to Figure 6 all top layers 8, 8 'have a multilayer structure made of plywood. Accordingly, layers 36 with a first orientation of the wood fibers (hatched) alternate with layers 38 (not hatched) of a second orientation of the wood fibers (not hatched) that is rotated by 90 ° for this in the exemplary embodiment.

It can be clearly seen that the external spring 32 is immersed in both grooves 26 up to their respective groove bottom. Since a depth of the tongue 32, measured from groove base to groove base, is greater than the sum of the depths of the grooves 26, a joint remains between the side surfaces 26 and 28 of the wall panels 4, 4 'in which a central section of the external tongue 32 is visible.

According to Figure 6 the panels 4, 4 'thus have a joint spacing of L from one another. According to Figure 6 In the middle on the right it can be seen that the damping layers 12 of the individual wall panels 4, 4 'each protrude beyond the side surfaces 24, 28 and are in contact with one another. In this way, the wall panels 4, 4 'can be mounted in directions perpendicular to the side surfaces 26, 28, or in the laying / mounting surface, with an elastic pretension of the damping layers 12 so that the damping behavior of the impact protection wall is improved. In addition to influencing the acoustics and / or the climate, the perforations 34 make it possible to inconspicuously attach the wall panels 4 to the wall, for example with screws. Their invisibility gives the wall construction 2 a very valuable appearance.

The embodiment according to Figure 7 largely corresponds to that according to Figure 6 . However, it has a supplement that is specifically aimed at cases with an uneven subsurface of the wall construction 2. To compensate for these unevenness, the wall construction 2 has an additional load distribution layer in the form of slats 40. In the exemplary embodiment shown, these are attached by means of screws (not shown). A height compensation of the unevenness of the wall can take place via the slats 40, so that a smooth appearance results on the other visible side of the upper layers 8, 8 '. For the defined attachment of the wall panels 4, 4 ′ to the slats 40, the wall panels 4, 4 ′ again have a carrier plate 20 at the rear, which is connected to the damping layer 12.

In principle, instead of the assembly bonding, a Velcro connection that ensures sufficient holding forces can also be used for fixing.

In principle it is possible - as mentioned above - to carry out the assembly by screwing through the visible side of the wall panel. Instead of the suspension 22, of course, other suitable mounting means can also be provided on the rear.

One advantage of the solution with a sandwich structure prefabricated at the factory is that the finished wall panels are delivered, so that only very little effort is required for mounting on the sports hall wall.

In principle, it is also possible to provide suitable tongue and groove connections on the peripheral edges of the wall panels 4, which can also be designed with locking elements for locking perpendicularly and parallel to the laying direction.

Instead of the plywood materials, other suitable materials, for example MDF / HDF panels or WPC elements (Wood Plastic Compound) or the like, can also be used for the top layer 8 and the carrier plate 20.

Disclosed is a wall construction and a method for assembling such a wall construction, wall panels with a top layer and a damping layer being designed as prefabricated sandwich constructions. The wall construction can be designed, for example, as a baffle wall, acoustic or design wall construction. Tongue / tongue-like connecting means are provided on side surfaces of the comparatively hard or tough top layers, by means of which the wall panels can be positioned on one another in a direction perpendicular to the mounting surface.

A method for assembling such a wall construction is also disclosed in which tongue / groove-like connecting means provided on the side surfaces of adjacent upper layers of the wall panels are connected in such a way that the wall panels are securely positioned on one another at least in the direction perpendicular to their large surface.
