Description

Tile for interior and dry construction and method of making new walls

Technical field

The invention relates in particular to a board for interior and dry construction, preferably for making new walls and claddings of a space, or for lining the wall, ceiling or roof surfaces of a space, according to the preamble of claim 1 and the corresponding method according to preamble of claim 28 .

BACKGROUND OF THE INVENTION

Large-format boards are known in the field of interior construction, for example of plasterboard, which are fastened to suitable beams. For example, in the area of dry construction, these panels are fixed to metal profiles for the production of new partitions. Alternatively, the lining panels may be mounted on a slat connected to the wall or on roof sloping girders, such as roof beams. The boards may be as high as human and have a width of more than 1 m. Such boards are known as single-walled boards and, for example, have dimensions of approximately 1.50 x 1.00 m. In addition, there are standard larger boards, such as 1.25 x 2. 50 m, which can usually be handled only by two people.

At the mutually adjacent contact edges of the plates, an as uniform and inconspicuous transition as possible must be provided. For this purpose, the contact edges of the plates are flattened in the contact area between the plates. Thus, the plates are skewed at the edge so that a relatively flat flattening occurs at the contact edge of two adjacent plates. It can be filled with sealant. Into the wet putty is subsequently _t

inserts textile strap. As a result, the plates are rigidly joined together, for example to prevent later cracks in the wallpaper placed over them.

DE 297 19 986 U1 discloses a panel element which can be connected to an adjacent panel element by means of a tongue-and-groove connection. The groove is bounded by two so-called groove sides. On that side of the groove, which is located on the side facing away from the room in question, recesses are provided for receiving the fastening means. By means of the fastening means described, said panel can be connected to the substructure.

A combination of a securing element with at least two panels is known from EP 1 120 515 A1, which is not disclosed in advance. The first panel is fastened to the substrate with a clip. The second panel with its tongue is inserted into the groove of the first panel and, due to the protruding section which is formed on the clip, is attached to the substrate and to the first panel.

A similar arrangement is known from WO 01/38668 A1, which is also not disclosed in advance. The panels are fixed by holding elements which are fixed to the substrate. In both of the aforementioned documents, the panel is secured by means of a separate securing or retaining element, so that the structure is relatively complicated, inflexible and burdened with extensive tolerances.

DE 100 01 076 C1 discloses a panel element which is intended for floor coverings and is provided with a special groove-tongue connection with which it is possible to form a locking connection with adjacent panel elements. In other words, at the moment of connection, at least one of the groove-defining sections is deflected at least briefly, and the locking connection is formed by moving this section back and gripping the projection formed on the tongue of the adjacent panel in a blocking manner.

DE 200 17 114 U1 discloses a panel element for floors, ceilings or walls, on whose bottom side of the groove a recess is formed through which a fastening element, for example a screw, can be screwed to connect the panel element to the substructure. The adjoining panel element is connectable to the first panel element fastened in this manner by a tongue design.

A similar embodiment for a panel is known from JP 11350706 A, which at least partially consists of a metal on its surface.

The plate according to the preamble of claim 1 is known from U.S. Pat. No. 4,299,070. This plate is formed by extrusion as a hollow plate and provided with tongue and groove connection means. Two notches are provided on the tongue, in which the projections, which are formed on both sides of the groove, engage. The projections are complementary to the notches. The sealing material, separate from the plate material, forces the fasteners together.

The method according to the preamble of claim 28 is known from DE 195 03 948 A1. In this case, the first plate already fixed to the support structure is connected to the second plate by a locking connection. Subsequently, a second plate is fastened to the support structure. The locking connection is provided with a connecting clearance so that the gap between the two plates can be changed.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to provide a board, particularly for interior and dry construction, which can be connected to other boards of the same kind in a pleasant and time-saving manner in a pleasant manner, creating a new wall or lining. Furthermore, a suitable method should be provided.

On the one hand, this is accomplished by the plate described in claim 1.

Accordingly, coupling means are provided on at least two opposite sides, the first and second sides of the plate, which, when coupled to other plates of the same type, allow a blocking connection to the adjacent plate. These connecting means may, for example, be in the form of a tongue groove. In particular, the coupling means on two opposite sides are complementary to each other, so that the side edge of one plate can be locked or secured together with the opposite side of the plate of the same kind. In this connection, a locking connection is understood to mean that at least a short-term deflection occurs in the joining area, in particular at one of the sections used, for example a groove flanking the groove, so that the locking projection, which is preferably larger in size, can be retained. In other words, in such a locking, snap-in or snap-in connection, the section moves such that it crosses the dead point, whereupon the section is resiliently at least partially moved back, so that the aforementioned locking projection is held securely. In the coupled state, in this way the moving section can remain at least partially deflected, so that a force is still applied to pull the plates together. However, it is also conceivable that no deflection occurs in the coupled state, but at the same time movement of the plates joined together is prevented. In connection with the fasteners provided on the plate serving the locking connections, it should be pointed out that they are integrally arranged on the plate. In other words, they are made directly in the plate material, so that expensive additional fasteners are not needed.

Such a locking connection has the substantial advantage that, in an unknown manner, interior building panels, which are intended to be fixed to ceilings and / or walls, can be joined visually without joints. By "visually without joints" it is meant that although a certain joint or contact point between two adjacent plates remains, the joint is of such a quality and thus the small size that is not noticed. In particular, this joint corresponds to a very well-executed wallpaper contact, so that a particularly well-positioned wallpaper appears or, in other embodiments of the surface, the joint is not recognizable.

The described locking, snapping or snapping connection prevents the movement of two adjacent plates from each other, so that a good external appearance is still ensured, without having to work the contact points between the plates in a special way.

In this way, a connection is formed between the two plates, which connects the two plates in all directions perpendicular to the side edge to be monitored. In other words, the two plates cannot be lifted relative to each other in a direction perpendicular to their surface. Furthermore, they cannot be separated simply from one another in a direction parallel to their surface. This is prevented by means of locking means. This securing is valid at least for the time during insertion, i.e. if the plates form a partition wall or lining. However, the fasteners can be designed such that, by properly releasing the plates, the plates can be separated and reused in another manner without damage and contamination.

The board according to the invention is characterized by the fact that fastening devices are provided on the board itself or on two interconnected boards for creating new walls or for cladding existing areas of the space, which enable fixing to the supporting structure. In particular, the fastening devices may be arranged at the connection point of the two interconnected plates in such a way that fastening or adapters made of metal or plastic can be fastened to the support structure. As further specified below, these additional fasteners can be designed such that the respective fasteners are fastened to the »» »·· Β

Β Β Β boards on a supporting structure using suitable clips, screws or nails. Adhesive or adhesive fastening to the support structure as well as fastening by means of a clamping or magnetic tape is also possible. In this way, it is advantageous to ensure that the two plates are reliably fastened not only to each other but also to the underlying structure of wood, metal or plastic. This may for example be formed by roof beams, so that the board according to the invention can replace the plasterboard used hitherto. Compared to gypsum boards, the board according to the invention provides a decisive advantage in that it is considerably lighter, namely approximately 30%, lighter than the gypsum board. This makes it transportable and mountable with less effort. Furthermore, the plate according to the invention is easy to process, for example by means of a thief saw or a hand-held circular saw. On the one hand, in the case of the board according to the invention, in comparison with the use of gypsum boards, the sealing of the contact joints as well as the grinding of the putty is eliminated. In addition, the extensive cleaning work usually required when using gypsum boards can be advantageously avoided. In particular, the slab according to the invention is advantageously suitable as a lining for suspended ceilings, lightweight partition walls, cladding and loft construction.

It should be noted that for the board according to the invention, dimensions of, for example, 2.65 m x 41.5 cm or 62.5 cm are currently envisaged. Furthermore, the so-called short plate length could have a length of approximately 1.3 m, preferably 1.285 m. Due to the locking means formed by the locking means it is ensured that the contact point between adjacent plates is inconspicuous and in particular not more noticeable to the viewer than wallpaper strips. In this way, the required joint sealing and the application of the textile tape can in particular be omitted. This makes work much easier and ensures a satisfactory and visually pleasing result. Furthermore, these connecting means ensure that the two adjacent plates are aligned at the same level with respect to their surface. If only placement on the underlying structure is used, it would not necessarily be guaranteed that the plates are at the same level, and interfering steps may occur on the surface. However, the fasteners provided on the plates can be formed so precisely that the surfaces of adjacent plates abut exactly.

Furthermore, the board according to the invention can be advantageously provided with suitable structural physical properties. For example, a plate according to DIN 4102 is rated B1 - hardly flammable. In addition, the required F-30B classification can be achieved for single-family or two-family houses. In addition, the noise and heat protection requirements can be advantageously met by means of the plate according to the invention. Especially in the MDF wood material, the board according to the invention can be evaluated as a low harmful material that meets the requirements of the blue angel. Finally, the board according to the invention can be made airtight or diffusion-tight to meet various regulations.

Advantageous further embodiments of the invention are described in further claims.

It has proven to be particularly advantageous in the embodiment in which the additional fastening means which serve to fasten the plate to the supporting structure are formed by means of at least one recess which occurs in the joined state of the two plates in the joining region of the two plates, securing clip section. In other words, in the connecting region between the two plates according to the invention of the same kind, a gripping space for the fastening clip section is arranged in a suitable manner. Thereby, the first board laid can be fixed to the substrate using one or more fastening clips. The fastening in this region is carried out by means of fastening clips in such a way that the subsequent connection of the second plate to the already fastened first plate prevents nothing. As a result, a plurality of boards can be joined together in an advantageous manner, both jointly and reliably, with the support structure. Particular advantage when using fasteners

The clamps consist in that the plate according to the invention can be movably positioned in all directions with respect to the fixing clamps. In particular, a larger surface, which is lined with multiple plates according to the invention, can move in a floating manner or work in a direction perpendicular to the respective contact points, so that even when shrinking or swelling the plates no joints are opened to move the clips by means of which the plates are held on the supporting structure.

For fixing the plate to the support structure, it has further proven advantageous to provide at least one groove which serves to hold the fastening clip section. Such a groove extends from the edge of the plate into the material of the plate, and the respective arm of the fastening clip may engage into the groove so that the plate is held on the support structure.

Alternatively or additionally, good experience has been made with at least one recess in the edge region of the plate that serves to hold the heads of screws or nails. These recesses can always be adapted as a recessed hole to the head of a single screw or a single nail. However, the recess may be formed as a groove for a certain length along the edge of the plate, so that the number of fastening means, i.e. screws or nails, to be used is freely selectable. Such a recess may in the broadest sense also be formed as a free space which occurs in the joined state of the two plates in the joining area of the plates and is suitable for gripping the screw or nail head as well as slightly overlapping buckle section .

In principle, any way of locking, locking or snapping is conceivable for the locking connection of two boards of the same kind. However, it is now advantageous to design the connecting contours in such a way that the second, newly laid plate, which is mounted on the first, already laid plate, is pivotable. In other words, the second

the plate is pivoted at least slightly around the contact edge between the two plates and locks.

For both the above-described exemplary embodiment and the exemplary embodiment of the locking connection, which is realized by planar insertion of the tongue into the groove, it is advantageous for the plate according to the invention that the lower side of the groove arranged on the view side. In the protruding area, for example, in the form of one or more recesses, a fastening device can be provided for gripping the head of the screw or nail or the like, without this having to be placed obliquely to some extent outside the upper side of the groove. Rather, it can be positioned in a region projecting from the upper side of the groove in a direction perpendicular to the surface of the plate.

For a locking connection between two plates of the same kind, it is furthermore advantageous that this is designed so that the two plates are displaceable against each other in a direction parallel to the blocked edges. As a result, the newly laid third plate, which is to be connected to the first plate in addition to the second plate already laid, is thereby created, after joining it with the first plate by sliding parallel to the joining edges on the perpendicular edges.

Thus, it is advantageous for the board according to the invention that, in addition to the first and second sides that are opposed to each other, the third and fourth sides of the rectangular board also have coupling means for a locking, snapping or snapping connection. In this way, as already described above, a particularly secure jointing of the boards in all directions can be realized in a advantageous manner without joints. Furthermore, it is possible to cover larger inner surfaces with a plurality of boards according to the invention without the boards themselves being excessively large and no longer controllable.

In this connection, the connection on the third and fourth sides, as is more precisely stated later, can be effected by a plane displacement or a downward movement in a direction perpendicular to the surface of the plates, in a certain way in the manner of a patent button.

For these fasteners on the third and fourth sides of the board according to the invention, it has proven advantageous to make this connection as a groove and a tongue, wherein the tongue, when coupled, 6 mm or less, preferably 4 mm or less, protrudes into the groove. This means that the considered, newly laid third plate must be displaced only by this relatively short section in order to secure the third plate on its third or fourth slope with the second plate already laid. This is particularly advantageous for the panel according to the invention, since only a relatively small gap remains with the ceiling when placing the top panel as a wall covering. Along with another, relatively small slit that may be required to deploy the tool in order to move the third plate accordingly, a slot of at most 8 mm is formed in the final state, which can be covered in a simple and visually pleasing manner using a suitable profile, e.g. or sealed with a liquid, permanently elastic sealant. It should be noted in this context that the described connection, which needs a relatively short path for locking or snapping, is a trend which is fundamentally independent of the above-described joining of the two plates according to the invention together with the underlying structure. In other words, such a blocking, snapping or snapping connection with a short path for locking or snapping, develops its special advantages without the features described above. In addition, this applies to all of the following examples of embodiments of such a locking connection on the third and fourth sides of the board according to the invention.

In particular, but not exclusively, it is advantageous for a groove arranged on the third and fourth sides that a recess is attached to the groove itself which serves to retain the tongue. It is advantageous for this depression to have, seen in cross-section

smaller width than the groove used to hold the tongue. In other words, the groove tapers in the direction of the interior of the plate to form said depression. This serves to provide the flanks of the groove that surround the groove with the flexibility required to form a locking or snap connection. In this way, the function and the described short locking path can be realized and at the same time a relatively small groove depth is sufficient. However, even with such a relatively low depth groove, the depressed recess creates a flexibility of the groove sides for locking.

Furthermore, an embodiment which is also conceivable for the first and second sides is also advantageous for locking on the third and fourth sides of the plate according to the invention. A groove is formed in the widest sense, which is open in the direction of the face side of the plates. According to this, the tongue extends on the opposite side in the direction of the back side of the plate. As a result, the two adjacent plates can be joined together in the manner of a knob by means of a movement substantially perpendicular to the surface of the plates. This joining method may be formed by either a linear downward movement in said direction on all four sides of the rectangular plate. In the case of a plate which is pivotable on its first or second side, the securing of the newly laid plate on the third or fourth side can be effected by placing it on the side in the correct position on an already laid plate and protruding towards the rear the pen will be inserted into the top of the open groove when rotated. In this way, a seamless surface with adjacent plates can be formed advantageously, without having to move the newly laid plate parallel to its first and second sides.

The additional plate fasteners according to the invention for placement on the support structure may further be formed by a self-adhesive layer which is arranged at least in certain sections on the back of the plate. Such a self-adhesive layer can be protected with a foil or the like until it is applied, so that the adhesive is activated only after the foil has been pulled off and then the board is secured to it after being pressed onto the support structure.

In certain applications, an advantage is offered as an alternative if the plate according to the invention has a suitable adapter for positioning on a section or element of the supporting structure. In this context, it should be noted that the supporting structure does not necessarily have separate elements which serve to position the plate according to the invention. Rather, the elements cooperating with the plate fasteners can also be arranged in one piece on the support structure. For example, the clip, which is explained in more detail below, may be formed as an integrated component, in particular as an extruded profile on the supporting or substructure. Thus, the fastening devices provided on the plate and the associated fastening devices of the substructure do not necessarily have to be formed separately from the plate or substructure. Moreover, the invention extends to the combination of the board according to the invention with fasteners which can be placed on the substructure or on the supporting structure, placed on it or integrated therein, since such a combination advantageously provides a particularly simple possibility of fabricating partition walls or lining interior rooms.

As a further preferred example of a fastening device provided on the plate according to the invention, at least one recess, for example milling, or at least one opening is provided which cooperates with the element or a section located thereon on the substructure or support structure in such a way that This structure is securely held. For example, the milling could constitute a blocking channel or a plurality of blocking holes into which a suitable section snaps onto the substructure, and the plate according to the invention is fixed to the substructure in some sense in the manner of a snap button. Further, it is conceivable to position, for example, screw the adapter on the back of the plate according to the invention. The corresponding counterpart would be fastened to the supporting structure and allow

pressing, sliding or locking the board according to the invention provided with one or more adapters.

Furthermore, it is advantageous for the board to at least partially consist of a wood material, in particular an MDF or HDF board, or alternatively a plastic. Further, the board according to the invention may at least partially consist of a variant of said materials modified with additives or additional layers. Moreover, a density of about 500 to 800 kg / m ³ , preferably about 750 kg / m ^3, is currently used for the MDF sheet. In the case of the plastic suitable for the board according to the invention, the density is less, in particular approximately 100 to 150 kg / m ³ . In the case of said materials, the contours in question can be formed with the necessary precision necessary to fasten two adjacent plates together as well as to fasten the individual plate to the supporting structure. Furthermore, a particularly pleasant surface structure according to the invention can be formed on the wood material on the surface of the wood by pressing the paper or foil by means of a melamine resin. In this way, on the one hand, cost-effective manufacture is ensured and, on the other hand, the trouble-free possibility of fastening such boards is ensured. With such wood-based materials, in particular as laminates with layers of melamine resin impregnated thereon, the surfaces described can advantageously be particularly realistic and rendered abrasion-resistant, scratch-resistant, impact-resistant and easy to clean. Finally, such panels are highly loaded because similar laminate panels are used, for example, as floor coverings, so that there is the possibility of using panels without further treatment as long-lasting wall or ceiling cladding. In particular, weights of up to 50 kg can be fastened to the board according to the invention by suitable fastening. In addition, the preferred MDF board material provides the advantage that it is a heat-friendly material whose surface is felt warm because the material has a low heat uptake coefficient. Furthermore, the wall lined with the board according to the invention is felt warmer on the concrete or brick wall or on the surface with lime-cement plaster.

t

Due to the external appearance of the plate according to the invention, advantages are offered if the additional fasteners are designed in such a way that they are covered in the joined state of the two plates. For example, a strip of material that projects beyond the edge of the plate, visible on the front, can be provided on the plate so that the plate can be nailed or screwed firmly onto the support structure. This strip of material may be covered by the respective edge of the adjacent plate.

Since it is important for the reliable connection of the two plates that the process takes place in a locking or blocking manner, the respective connecting means are designed such that a pressure fit is formed between the two joined plates. Accordingly, the two adjacent plates lie together under tension and there is no risk of an unsightly joint between the two plates.

One particularly advantageous embodiment of the board according to the invention is that it is designed as a cladding or a partition wall, and has one or two surfaces suitable as interior surfaces of the room. In this way, a partition wall for the room can be created in a particularly simple manner. As a supporting or substructure according to the invention, in which case, in the case of a blocking connection between two adjacent plates, a plate according to

According to the invention, there is provided a ceiling or a floor as well as any customized rack profiles on which the board can be placed by suitable fasteners.

In this case, the plate according to the invention may also have a multi-layer construction and be provided with an intermediate layer. Such an interlayer may consist, for example, of a honeycomb or hollow plate, for example of plastic, or preferably of a 40 mm thick clamping plate, which on both sides is sheathed with a plasterboard according to the invention in place of the hitherto known plasterboard. According to the invention, by means of the blocking connecting means, a partition wall can be made in this manner considerably simpler than is currently possible according to the prior art, in which partition walls are produced in a costly manner by means of struts and gypsum boards. It should be noted that in this case, the locking fasteners may be formed both on the intermediate layer and on the at least one top layer. The fastening without the use of webs can be realized, as already mentioned, for example by means of construction strips arranged on the upper and lower edges, which are fastened to the floor and ceiling by dowels.

Preferably, the board according to the invention has a surface which is provided with a typical surface structure of a crafted wall cladding, in particular with its projections and depressions. As an example of such a crafted wall cladding which is already made in the shop according to the invention, be it wallpaper, a plaster surface, in particular a fine, coarse or textured plaster, or a surface formed by a painting technique, or a plastered surface. As is obvious, such surfaces to be formed on existing walls or linings, in particular of plasterboard, must be produced by a plurality of individual work steps. The production of such a wall cladding is usually associated with six working processes, namely sealing the joint between the boards, grinding, substrate preparation, wallpapering, priming and finishing. Furthermore, all of this entails considerable pollution and the necessary removal of numerous different small materials. By means of the plate according to the invention, all the six working steps described, as well as the cleaning and disposal work, can be saved.

Preferably, such a surface structure is already provided on the plate. In order to form a wall, in particular a partition wall or lining with a corresponding external appearance, only a plurality of plates must be placed side by side. None ··· * »• · 9 ·

99 no additional work is needed, in particular investment, finishing, or wallpapering and painting processes. The six working steps mentioned can be saved, which in general leads to a saving of time in interior construction or in dry construction, and this allows room tiling two to three days earlier.

In addition, it should be noted that the surface of the board according to the invention can be advantageously designed so that it can be painted with a conventional color or provided with a wallpaper or tile layer. This may, if desired, at a later time, if desired by the user, as is customary for wall-paper cladding, a different color or surface finish. By means of such a plate according to the invention, which is, for example, provided with a base foil, four working steps, namely cementing, grinding, surface treatment and priming, are always dispensed with compared to conventional processes. Alternatively, the board according to the invention may consist of the above-mentioned materials, in particular an MDF board, and be modified or coated with an additional fabric or additional layer so that the board becomes coated by the above-mentioned working steps. Furthermore, the board according to the invention could also be left in its original state and in that state coated or painted. As structures which can be formed on the board according to the invention, all structures that are possible and customary for the interior of the rooms are conceivable. For example, an exterior appearance that matches the exterior appearance of the plaster walls may be formed by a suitable structure. Furthermore, structures known from wallpaper can be formed. For example, the outer appearance of the coarse fiber may be formed. Furthermore, glass fiber mats are known as wallpapers, which are essentially formed by a relatively coarse fabric. The structure thus formed can also be arranged on the surface of the board according to the invention. The same applies in the same way to fiberglass nets. Irrespective of the particular surface design, the panel according to the invention will greatly simplify the construction of the interior, since the placement of the panel according to the invention can eliminate the numerous steps necessary to create the final wall cladding. Furthermore, as a crafted surface which can be imitated by the board according to the invention, a tiled surface is mentioned.

A particularly pleasant external appearance of the plate according to the invention is obtained if it has such a color, which also corresponds to the color produced in a craft. In particular, irregular coloring is intended, as is the case, for example, in the context of wiping, roller or sponge techniques. In other words, expensive and crafted interior wall coloring can be replaced in this way by the corresponding coloring on the board according to the invention. Consequently, the production of the partition wall or the interior lining of the room is associated with considerably lower costs for the user, in particular the advantage of assembly time and expense and less pollution. The coloring of the surface of the panel according to the invention acting as a viewing surface may further correspond to the external appearance of wood or veneer as well as the decoration of stone, tiles or so-called fancy decor, which may be of any design. Furthermore, the board according to the invention can be provided with a real wood veneer on its face. In addition, modifications of said materials and surface layers are conceivable. In particular, the board may be provided with any suitable surface layer. Examples are cork or plastic, natural or artificial stone, applied cement, fluidized stone, optionally modified with additives or admixtures.

For the external appearance of the board according to the invention and in particular for the external appearance of several adjacent boards, advantages are offered if the surface structure is irregular over at least the entire surface of the board and preferably over the surface of several boards of the same kind. It is to be understood that the surface of the board according to the invention is not merely formed by the multilayer bonding of a particular small-format surface structure. This would lead, notably for the inexperienced observer, to an external appearance in the form of repetition. In contrast, it is advantageous for the plate according to the invention that the surface structure is irregular over at least the entire surface of one plate and, in the worst case, repeats on the adjacent plate. However, it is preferred that the surface structure is irregular over several adjacent plates, which can, for example, be suitably provided by large-format presses in the manufacture of the plate according to the invention, as described more precisely below. In this case, the surface structure repeats over a sufficiently large distance so that in any case there can be no impression of repetition. Rather, it gives the impression of an irregular, crafted surface structure. Alternatively or in addition, the front side of the plate may also be colored in another way. Thus, for example, in addition to the surface structure, an appropriate color scheme can be provided, for example a tile pattern, wood decor or the like. If desired, however, the color design of the front side without three-dimensional structuring can also be exclusively considered. In this case, the color design can either complete the play of light and shadow of three-dimensional structuring, or it can imitate the coloring of an even smooth wall cladding, for example a decorative wallpaper pattern.

Because of the susceptibility of the board according to the invention to dirt and the versatile use of the blanket according to the invention, it has proven advantageous to provide a moisture-resistant surface seal on the front side of the board. Advantageously, the front side may have a moisture-repellent coating or surface sealing coating so that a particularly easy-to-treat surface is formed which can be treated without difficulty with wet cleaning agents.

The plates may be preferably rectangular. A sealing material may be provided on the long edge or on the long and short edges, so that an elastic abutment on the adjacent plate, adjacent to the adjacent plate, extending in both the longitudinal and transverse directions may be facilitated. In this way, slight movements caused, for example, by the expansion of the materials, are compensated for by the deformation or loosening of the elastic sealing material, without causing open, clearly visible joints between adjacent plates. It should be noted that, alternatively, it is conceivable to admit or even emphasize the joint at this point. For example, such a joint with an external appearance that corresponds to the external appearance of the wallpaper contact may be allowed so that it can be tolerated and supported by the impression that it is a crafted wallpaper surface. Alternatively, the edges of the board according to the invention may be formed obliquely so that an accentuated joint is formed in the contact area, for example a V-shaped channel, into which, for example, a colored grout material can be introduced.

Instead of said sealing material, glue may be used on the board so that a secure connection with adjacent boards can be achieved and opening gaps can be reliably prevented. For trouble-free, user-friendly glue handling, it may be desirable to provide the glue with a tape that can be removed prior to mounting the board or to use a two-component glue, with one component of the glue provided at opposite edges of the board. Only when two boards are joined together, if they are mounted close to each other, the two components of the adhesive are joined together and cause gluing.

Although a tight and seamless joint between two adjacent plates can be provided by suitable locking contours, in certain cases the use provides the advantage if two adjacent plates are joined together alternatively or additionally by means of an adhesive. In this case, this provides advantages if an adhesive-receiving channel is provided in the region of the adjacent edges, which is filled with adhesive in the bonded state.

It also provides advantages for a pleasant external appearance if a protective tape, in particular a self-adhesive protective tape, is provided on the surface at least along the edges on which adjacent boards are applied, which can be removed if

if a connection is established between adjacent plates. Particularly when using an adhesive, the surfaces of the boards are thus protected from dirt.

A further simplification for the user can be achieved by a preferred embodiment in which the board according to the invention, preferably on the back, is provided with an insulating material, so that such a material need not be placed separately. This may be both a thermal insulation material and a sound insulation material. For example, an acoustic or sound insulating mat with advantageous sound-insulating properties may be advantageously placed on the back of the panel, which must usually be only a few millimeters thick to prevent the sound from propagating through the body. Furthermore, an insulating mat, for example of expanded polystyrene or polyurethane, with a thickness of, for example, 60 mm to 80 mm, can be provided for advantageous reduction of the sound transmission and for thermal insulation. Thus, the thermal and acoustic insulation properties of the board according to the invention can be influenced. Furthermore, a heating or air-conditioning device or a heating or air-conditioning structural layer can also be advantageously, but not limited to, generally expressed on the back of the board according to the invention. This can be, for example, a heating foil which has a relatively low density and is provided with metal foils or wires which are heatable by the passage of electric current, so that the board according to the invention can act as a heat source for the room. Alternatively, it is conceivable that such a heating foil is arranged on the view side of the board according to the invention, under a generally arranged decorative paper, or also as a visible surface of the board according to the invention, in a sense to form a visible technical substrate. As a result, such a heating film becomes an integral part of the interior building board and is not glued to the interior building board itself. In this context, it should be pointed out that this integration of such a heating film or any heating device by molding, in the manufacture of a laminate, into a laminate constitutes a novelty that is independent of the above-described invention and its various embodiments. In other words, for the first time, this is a laminate plate with an integrated heating foil or heating device. In addition to the heating film, it may be noted that it may have, to some extent, the current printed circuit board or base plate, such as a printable metal, flowable, or heat transferring.

Shrinkage may occur within the boards or support structure, for example due to moisture and / or temperature changes. Therefore, it is advantageous to realize that the plates are fixedly movable on their supporting structure, i.e. a floating lining is realized, so that the material of the supporting structure itself or the plates can be expanded without collapsing or corrugating the plates. On the other hand, the plates are preferably fixedly connected to one another, for example by means of said locking connections or by gluing.

If such a rigid and tight connection of the plates is not used, the clearance of the plates relative to each other can advantageously be compensated by the aforementioned sealing materials. In this way, a smooth, closed surface is formed without opening the joints.

While the width of the individual panel elements lies around a maximum of about 30 cm from the floor area, the single-walled panels contemplated according to the invention may have widths of over 60 cm. For example, they can be sized to accommodate the usual dimensions of the wallpaper strips, so that, as mentioned, the design of the contact edges and any unevenness therein gives the same appearance as the visible edges of the wallpaper strips glued together.

For the plates according to the invention, a relatively low degree of gloss of the surface, for example 2.5 to 5 points of gloss scale, as measured by a gloss degree meter (Dr. Lange, measuring angle 60 °) can be envisaged. This can be achieved by a corresponding laminate design, for example using appropriate presses. Such presses themselves

the uppermost layer of the laminate is known in a manner known per se, so that the surface design and especially the surface roughness can be influenced by such presses. Irrespective of the design of the presses, the surface roughness of the sheets and thus the surface roughness of the laminate layers can be influenced, for example, by the types of paper used, the degree of curing or, optionally, with liquid or solid additives. Thus, for example, coarser paper or additives may be used in or in addition to the resin.

Such a higher surface roughness compared to floor coverings not only causes the visually desired matt surface of the boards, but also enables better adhesion of paints or paints. In this way, the individual panels or all the ceiling or wall trim made are overcoatable, either to affect colors immediately when making the wall or ceiling trim or to change the appearance of the wall or ceiling trim after a certain period of use.

For the panels according to the invention, or for wall and ceiling cladding, for example, it is possible to realize that the panels are made breathable. For this purpose, for example, in the manufacture of laminate layers, decorative paper of the desired color may be used, for example coated with a melamine resin. The decorative paper may be printed according to the desired pattern with a visible or invisible substance which repels the subsequently melamine resin so that the airtight seal coating otherwise caused by the melamine resin is interrupted. Since the slabs are usually not subjected to such high humidity loads in the wall or ceiling area as in the floor area, such an interruption of the sealing layer can be done without adversely affecting the longevity of the slabs or wall and ceiling cladding. In this way, vapor-permeable walls and ceilings are enabled.

(IN·

In order to achieve a large-area, uniform external appearance, it is necessary to avoid the gap between adjacent plates. Advantageously, an embodiment may be realized such that both the adhesive and the edge design are used which, on their side, allow blocking of adjacent panel elements. The blockage can be emphasized relatively weakly, so that the plates can be joined together in a simple manner without having to overcome the high compressive forces. The blockage must, if a supplementary adhesive is envisaged, hold adjacent plates only until the adhesive has dried and has taken over the final connection of the two plates. The use of tensioning strips, as is known in the art for gluing panel elements, for example on floors, is in this way redundant, so that a rapid workflow is promoted.

As an alternative to the presses, profiled rollers can be used, for example. For example, in order to achieve a corresponding roughness depth in the surface of the board material, it can be supported by using the laminate as the board surface with appropriate paper, for example paper of greater weight than the usual basis weight of about 70-80 g per square meter. usual resin. In addition, additional layers may be used as the so-called Underlays to increase the compressibility of the laminate surface layer and thereby allow particularly high roughness depths.

Advantageously, the board according to the invention can be manufactured in a particularly inexpensive manner such that, on the one hand, the various laminate layers are known per se, as well as the core, which may consist, for example, of wood material and paper, at the same time joins the stock. This can be carried out in a particularly advantageous and energy-efficient manner, at a pressure of approximately 40 kp / qcm, so that such laminate sheets can be manufactured at a much lower cost than in the known production of HPL or CPL boards in which the laminate is first finished, Thus, at a substantially higher pressure of approximately 70 kp / qcm, they are joined to the core and the backing material in a second working step.

The solution according to the invention is further carried out in the manner described in claim 28, in particular for the construction of new room walls or for the cladding of existing room surfaces.

According to him, first mount the first plate. Subsequently, the second plate is joined to the first plate to form a locking connection at adjacent side edges of the two plates, preferably at their longitudinal edges. Subsequently, the second plate is secured by means of additional fasteners. As already mentioned, the second plate is preferably fixed to a separate support structure. With the method according to the invention, secure fastening of panels can be carried out at low cost for creating new walls, in particular partitions, or for lining the wall, ceiling or roof surfaces of a room. As a result of the process according to the invention, a pleasant external appearance is also obtained, since no additional work is required with respect to the surface. Furthermore, it is ensured that no steps are formed at the contact points of the two adjacent plates, since the arrangement at the same level is guaranteed by the locking connection according to the invention.

Advantageous further embodiments of the method according to the invention are described in further claims.

The plates can advantageously be laid by pivoting movement while being locked. Particularly in unfavorable working positions, for example when working over the head, easy-to-manage and quick laying of the boards and at the same time a secure, firm connection of the joined boards can be achieved. For example, the first plate is laid first. The second plate with its tongue is attached to the side edge of the first plate, The tongue is provided with a groove and the tongue is inserted as far as possible into the groove. By a subsequent pivoting movement, the second plate is brought into common plane with the first plate and a proper locking can occur. However, it is naturally also possible in principle to reverse the method of laying by placing the second plate with its groove on the tongue of the first plate and then turning it. For this pivoting movement, it should be noted that it can run both on the short and long sides of the plate according to the invention. The connection to adjacent plates may take place on the other, that is, the long or short side, as will be explained more precisely thereafter, by planar displacement or downward movement perpendicular to the surface of the plate in the manner of a patent button.

Alternatively, however, it is possible to realize that the two plates are arranged in a common plane before their joining and the two plates are joined together by a clean lateral displacement. The locking connection can be achieved, for example, by corresponding edge profiling of the panel elements, the edge profiling preferably being designed to facilitate insertion of both boards with as little resistance forces as possible so that when pushing over the entire 260 cm board the user can easily exert sufficient compressive forces.

As mentioned above in connection with the board according to the invention, for example, fastening clips and corresponding grooves can be used as fastening devices on the board. Alternatively, the fastening may take place by means of self-adhesive layers or screws or nails, which are suitably combined with recesses formed on the board.

In the method according to the invention, it is further preferred that, according to the first and second plates, the third plate is mounted in such a way that it connects to both the first and second plates to form a locking, snap-in or snap-fit connection. As a result, the plates according to the invention can be joined together continuously, not only in the

44 4 · 4 44 4444 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4. 4 4 direction. Rather, the larger surfaces can be laid with the boards according to the invention in such a way that not individual boards, but rows of more boards, are arranged side by side. The above-described second and third plates form a series of such type that is located together next to the first plate to be considered.

For certain applications, it is advantageous for the third plate to be connected to the second plate by means of a rotation in which the connection contours on the contact edge between the second and third plates come into engagement.

It is furthermore advantageous for other applications that the third plate is displaced at least slightly parallel with its connecting edge to the first plate to join with the second plate. Advantageously, this displacement takes place, as already described in connection with the plate according to the invention, around a relatively short path for example 6 mm or less, preferably 4 mm or less.

As an alternative to this blocking or snapping connection method, the connection between the third and second plates may coincide to some extent with the joining of the third plate to the first plate so that the third plate is lowered perpendicularly to the plate surfaces at its contact edge with the second plate. In this area, the appropriate locking contours are brought into engagement with each other. This movement has already been described above as a patent button.

As a further alternative, it is possible to realize one that allows higher holding forces and higher blocking forces of adjacent panel elements by edge profiling, in which case the panel elements will not slide together over their entire length of 260 cm, but the two panel elements first they align in a common plane, but are sloping together so that a V-shaped slot is formed between the two plates. By pivoting the second plate, the slot can be closed, so that only approximately a point-of-contact point is 1111 lili. · · · ·

111110 111 1 11 111 119 1

H 11 11 11 arises where relatively high forces have to be exerted due to the blocking of the two plates. Due to this only approximately point-to-point contact of the two plates, the two plates are joined in a zip-like manner, so that the closing forces for both plates need only be applied to the respective approximately point-like areas. In this way, the mounting of the plates is simplified and the applied forces are reduced, while at the same time high holding forces can be ensured.

The laying methods described above may be carried out on two opposite sides of the board, for example on both longitudinal sides. If the tongue-and-groove profiling is also provided on the two remaining sides, i.e. on both ends, this may advantageously allow a net sliding movement of the two plates, so that said second plate is first joined on common longitudinal edges to the first plate and then longitudinally displaced with the third plate on common front edges.

If edge profiling is provided for the plates, this can be formed directly from the material of the plates itself, for example, milled. However, special profile rails can also be used, which are located on the edges of the board itself. Thus, for example, preformed preforms already prepared with final profiling can be used inexpensively as such profile rails and connected to the plate itself.

However, profile strips of material can also be used, which, for example, are better suited for profiling edges than the board material itself for better dimensional stability. In this case, the strips may be placed on the board first, and then the board is guided through a profiling device, for example a milling machine.

Further, the molding can be made of a freely moldable material, for example a liquid plastic or plastic foam, and during its shaping

0 0 * * tt 00 0000 • · · «0 0 0 0 0 • 0 · 0 0 0 0 0 0 0 00 0 * 0 0 0 • 0 00

it can be glued to the plate. In such a case, the plate may be guided along an adequately contoured hollow mold, wherein the hollow mold is filled with plastic or plastic foam, and wherein the foam or plastic is glued to the remaining plate. Particularly when the respective pressure is applied, for example due to the expansion behavior of the plastic foam, an internal connection of this material to the board material can be achieved if the board material is porous, for example in the form of a wood material. Alternatively, such a bar can also be shaped as a blank onto the board itself, and in a second working process, for example by milling, the blank can be provided with the desired profile contour.

When the plate is fastened to the supporting structure by the appropriate auxiliary means, for example by means of fastening clips, screws or nails, it is particularly advantageous if the plates allow direct bevelling of adjacent plates, for example either by the plate material or by inserting adhesive or sealant. a uniform, permeable embodiment of wall or ceiling cladding, as is, for example, obtainable and known for a wallpapered or plastered surface.

BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The invention will now be described, by way of example only, with reference to the accompanying drawings, in which: FIG. 1 to FIG. 8 and 10 to 14, in cross-section, the joining region of two interconnected plates in the third and fourth side regions.

DETAILED DESCRIPTION OF THE INVENTION ** ** ** * - - - - - - - - - - - - - - - - - - - - - »» · 9 φ 9 Φ $ «· * · · Φ · Φ Φ *

In the schematic view of FIG. 1, two boards 1 of the same kind for interior construction are shown, one board 1 having a groove 2 and the other board 1 a tongue 3 which extends into the groove 2 of the adjacent board 1. against forces acting transversely to the plane of the plates, which are trying to lift the plates from the supporting structure. In the opposite direction, the plates 1 are secured by application to a supporting structure (not shown in FIG. 1). For both the exemplary embodiment of FIG. 1 and all the other embodiments described herein, it should be noted here that the surface of the plate 1 according to the invention, which in the illustration in FIG. an area that is designed to be oriented inside the rooms. This viewing surface is recognizable in FIG. 1 so that on this surface the two adjacent plates on the contact surface 7 have no visible joint. In all other figures, on the other hand, the viewing surface is formed by the surface shown as the lower surface.

Against the separating forces pulling the plates 1 apart, which act transversely to the longitudinal edges of the plates 1, the plates 1 are secured by a contact surface 4. Along this contact surface 4 is a rib 5 formed on the underside of the tongue 3 on the side wall of the retaining channel 6, so that blocking of both plates 1 is achieved.

The forces applied to these separating forces in the opposite direction, which the two plates 1 try to move against each other, are absorbed by the contact surface 7 on which the two plates 1 abut and which extends from the front side, i.e. the surface of the two plates 1. facing the interior of the room, towards the rear of the load-bearing structure.

In the laid-down state shown in FIG. 1, in which both plates form part of the wall or ceiling cladding, four contact points 8a to 8d are formed, the contact point 8c being identical to the contact surface 4. Due to these four linear or surface contact points 8a 1 to 8d, the two plates 1 are fixed with respect to the separating or deflecting forces, so that only parallel movement of the two plates 1 in their longitudinal direction relative to each other is possible, without the frictional forces having to be overcome. In particular, the profiling of the interlocking edges of the plates 1 are designed such that four defined contact points 8a to 8d are formed. In this case, two separate contact points 8c and 8d are formed in the front region of the groove side having the retaining channel 6. The contact point 8d ensures an exact positioning of the plates in a direction perpendicular to their surface. In the same way, the contact point 8c ensures an exact positioning in a direction parallel to the surface. In this case, the distance, measured parallel to the surface of the plate, between the contact surface 7 and the inner, right flank of the rib 5 according to FIG. 1, may be greater than the distance between the contact surface 7 and the contact point 8c in the holding channel 6, pressure fit. In addition, the transition between the retaining channel 6 and the leading edge of the respective groove side is rounded with a relatively large radius in such a way that the rib 5 in the retaining channel 6 is gradually but still noticeable.

FIG. 1 shows the connection of the two plates 1 without the aid of an adhesive. However, the recess 9 above the tongue 3 and below the upper contact surface 7 can serve as an adhesive receiving channel to accommodate the excess adhesive if the two plates 1 are to be permanently and jointlessly joined together with the adhesive.

The plates 1 can be laid by means of a pivoting movement while being locked. For example, the left plate 1, from which the groove 2 is visible, is laid first. The second plate 1 with its tongue 3 is sloped on the side edge of the first plate 1 and the tongue 3 is inserted as far as possible into the groove 2. This is facilitated by the groove 2 having an upper edge 10 which extends towards the mouth of the groove 2. σ · ascending and in this way forms the insertion channel 11 seen in particular in FIG.

1.

Likewise, the tongue 3 has a lower side 12 which is inclined to the free end of the tongue 3, thus extending in an ascending manner so that the right plate 1 can be inserted into the groove 2 as far as possible in its inclined position. This insertion movement is limited, on the one hand, by the contact of the tongue 3 with the upper and lower boundary edges of the groove 2 and, on the other hand, by the contact of the two plates also in the region of their upper contact surface.

7. The subsequent pivoting of the right plate 1 causes a complete insertion of the tongue 3 into the groove 2 and a blockage on the contact surface 4, which is apparent in FIG. 1. Moreover, with respect to the embodiment shown in FIG. 01/51733.

FIG. 2 shows a second exemplary embodiment similar in principle to the blocking geometry of the edges of both panels 1, but this geometry causes less effective blocking of both panels 1, as compared to conventional floor panels, considerably larger interior panel dimensions and correspondingly longer lengths It may be advantageous to provide a lower blocking resistance of the edges of the boards so that the laying of the boards is simplified. Alternatively, it is also possible to realize different edge geometries on different sections of the peripheral edge of the plate, for example, in a rectangular plate, the edge geometry is different on the longitudinal edges than at the leading edges. It should be noted that the formation of a tongue-and-groove connection with the retaining rib on the side of the tongue 3 directed towards the support structure 15 and the recess in the respective groove side is provided so that the two adjacent plates can be joined together by sliding in a plane. In other words, the plate shown in FIG. 2 on the left is first mounted by means of a fastening clip 16. It should be noted that the fastening clip 16 is, of course, fixed, although not shown in the drawing, to the support structure. This can advantageously be done with flat head screws which

They do not protrude over the surface of the fastening clip and thus do not prevent the placement of the plates according to the invention. Alternatively, a screw head of another type may also be located in the cavity which can be seen between the crossbar 18 and the edge of the plate. After mounting the first plate shown in FIG. 2 on the left, the second plate vpravo shown at right is mounted laterally and applied to the support structure. By sliding parallel to the surface of the plates, the tongue enters the groove and forms a locking connection by the interaction between the retaining rib and the retaining channel for the retaining rib.

In the embodiment shown in FIG. 2, a seal is provided between the two plates 1 in the region of the contact surface 7. For this purpose, an additional strip of sealing material 14, for example a silicone strip, is used which, for rapid installation, can already be sprayed onto one of the two plates i or can be fastened to one of the plates if desired by the user.

The fastening of the two plates 4 to the structure 15 shown schematically is carried out by means of fastening clips 16. These consist of a base plate 17 which can be connected to the structure 15 by adhesive, nails, screws or the like. From the base plate 17 extends a crossbar 18 and a bent wing 19 therebetween into the groove 20 of the left-hand plate 4. As can be seen from FIG. 2, the fastening clip 16 has a relatively wide base plate 17. This base plate can have the rest of the fastening clip 16 a certain dimension in the direction perpendicular to the drawing of FIG. 2, so that a strip-like fastening clip 16 is formed. However, the wing 19 may also extend at an angle so that, in cooperation with an adequately oriented groove 20, it causes a certain clamping effect in the plate 1. It is shown purely schematically that the plate 1 does not extend beyond the groove 2 up to the crossbar 18. The orientation of the two plates 1, for example the perpendicularly oriented orientation of the longitudinal, rectangular plate 1, is realized in such a way lean against each other.

However, it can also be realized that either the plate shown in FIG. 2 to the right with its section behind the tongue 3 or the left plate 1 with its section beyond the groove 20 extends as far as the crossbar 18 of the fastening clip 16, the desired orientation, for example the vertical orientation of the plate 1, is ensured, and the plates 1 are prevented from being arranged obliquely. In any case, however, it is assumed that the two plates 1 do not extend up to the crossbar 18, but rather that there is more free space to allow the plates to expand, for example due to differences in humidity and / or temperature. In this way, the floating laying of the slabs 1 is allowed, so that they can work according to the material specification without tearing or tearing forces or pressure walls or ceilings / ´.

Giant. 3 shows an exemplary embodiment similar to that of FIG. 2, but no strip of sealing material 14 is provided, but gluing of the two plates 1 is accomplished by means of adhesive 21. The recess 9 is filled as adhesive adhesive channel 21 over the surface. The glue 21 and the protruding adhesive 21 can be removed by means of the tool 22 shown schematically.

For example, the tool 22 may be a knife with which the adhesive 1 is preferably removed after it has partially or completely solidified. For example, the tool 22 may also be a scraper with which the adhesive 21 can advantageously be removed if it is not yet completely solidified or is still soft or pasty.

In order to prevent damage (by knife) or contamination (by squeegee) to the surfaces of the plates 1 when using the tool 22, a self-adhesive adhesive tape 23 is provided on the surface along the longitudinal edges, which can be peeled off after the excess adhesive has been removed.

In the embodiment shown in FIG. 3, it is purely contemplated to provide an optical enhancement of the connection points between the two plates. For this purpose, the two edges of the plate 7 are chamfered, and in this V-shaped joint the adhesive 21 is trapped. An edge-free edge design, similar to FIG. 2, where glue 21 would then be used instead of sealing material 14, .

Giant. 4 shows boards in which no blocking of the boards is provided, but here the two boards 1 are firmly joined together only by means of an adhesive 21. This extends far into the edge region of the boards 1 and can for example be already shop-mounted:

Thus, for example, a one-component adhesive may be used, which is first protected from solidification by a protective tape. After removal of the protective tape, the two plates 1 can be joined together so that the adhesive can then solidify and the two plates 1 are joined together.

Alternatively, it is possible to realize that the two co-operating edge portions of the two sheets are each coated with one component of the overall two-component adhesive 21 so that when the two sheets are joined, both components of the adhesive react and the adhesive is activated.

Purely by way of example, in the exemplary embodiment of FIG. 4, a visible groove is formed in the region of the contact surface 7 in order to deliberately achieve the optical structuring of the wall and the ceiling lining.

• frfrfr • frfrfr

Giant. 5 shows an exemplary embodiment similar to that of FIG. 2, in which, however, the plates 1 abut one another in the region of their contact surface 7 without sealing material disposed therebetween. By means of a locking connection, in particular by the position of the contact surface 4, a pressure fit occurs between the two plates, so that the two plates are firmly adhered to one another in the area of the contact surface 7.

In this embodiment according to FIG. 5, a particularly inconspicuous connection is possible between the two panels 1, so that a particularly large impression of the entire wall lining or ceiling is obtained, for example similar to the flat impression of wallpaper, in which the individual wallpaper strips are adjacent.

The plates in FIGS. 6 and 7 correspond essentially to the embodiments of FIGS. 4 and 5, but the fastening of the plates to the carrier cone 15 is not carried out by means of fastening clips 16 but by screws 25 which are generally as in the illustration. 1 to 7 are shown schematically. The plates 1 shown to the left each have a groove 26 behind their groove 2, protruding over the edge of the plates visible from the front, the screws 25 extending through the groove 26. In order not to obstruct the overhang of the screw heads and to ensure smooth insertion of the tongues 3 into the groove 2, recesses 27 are provided in the groove spine 26 which can, for the most part, accommodate the screw heads completely or as in the illustrated embodiments.

These recesses 27 can be arranged in the recesses 26 of the grooves as point recesses, so that, for example, the user can be instructed in the locations and number of screws 25 to be used to fasten the plates. However, the recesses 27 may also be formed as a groove that extends over the entire length of the groove 26 so that the user can always select a suitable mounting location according to the embodiment of the support structure 15.

It is common to all the mentioned embodiments that the plates 1 are shown purely schematically. Apart from this purely schematic representation, they preferably consist of two or more different layers or materials; on the one hand, a core material, for example a wood material, on the other hand, a surface, for example a laminate, wherein the laminate itself may in turn consist of layers of different materials. In particular, this surface may be three-dimensionally structured, that is, it may have depressions and / or protrusions.

Likewise, in FIGS. 2 to 7, only the supporting structure 15 is shown purely schematically. This may be, for example, an aluminum profile, as is usual in a dry construction shop. However, the load-bearing structure 15 may also be a wood slat construction or existing ceiling or wall elements such as masonry, roof beams or the like to be clad with slabs 1.

In the embodiment of FIGS. 8 and 9, the construction is similar to that of the above-described embodiments. In particular, one of the plates 1, in the left-hand plate in FIG. 8, has a tongue groove 2, which is arranged on the right-hand plate shown. In this case, the groove and tongue, in contrast to the above-described embodiments, are designed for tilting movement of the plate which can be mounted on the left plate shown in FIG. 8 on the right. For this purpose, for example, the groove side facing the room side surface is provided with a bevel 28. The tongue 3 is rounded on its side facing away from the room and has an inclined surface 30 on its side facing away from it. an inclined surface 32 of the groove flank further away from the interior of the room. A retaining channel 6 is provided on this groove side, which has a rounded transition 34 to the front side of said groove side. At this rounded transition, the rib 5 protruding on the tongue arrives in a locking manner or by snap engagement. Thus, • · φ · the two plates can be joined together without joints. Moreover, in the embodiment of FIGS. 8 and 9, a particularly advantageous variant of the abutment of the two plates 1 at the four defined points described in connection with FIG. 1 is realized. The first first contact points 8a and 8b are located in the front region of the tongue 3. the tongues facing the face side, or the tongue side facing away from the face side. The third contact point 8c is located at the contact point between the protruding rib 5 and the rounded transition 34 of the retaining channel 6. However, unlike the embodiment of FIG. 1, the fourth contact point 8d is not between the retaining channel 6 and the leading edge 40 of the lower groove side. In this area, a free space is required for the fastening clip section 19 in order to define the two plates with respect to each other in a direction perpendicular to their surfaces in their position, in the embodiment of FIGS. 8 and 9, a fourth contact point 8d is provided. in the contact area between the inclined surface 30 of the tongue 3 and the inclined surface 32 of the sides of the groove, of the reverse side of the front side. As already mentioned, the fixing of the position in the direction perpendicular to the surfaces of the plates takes place essentially through this contact point 8d. The definition of the position in the direction parallel to the surfaces of the plates 1 and the jointless connection between the two plates is achieved by the contact point 8c. In particular, the dimension between the contact point 8c and the upper edge of the plate 1 seen from the plate having the tongue 3 is slightly larger than the corresponding dimension between the upper edge of the plate seen from the groove and the rounded transition 34 of the retaining channel, Here, a pressure fit occurs. Moreover, the described arrangement of the four contact points 8a to 8d is a measure which must be seen to be independent of the use of additional fastening devices, for example in the form of fastening clips 16, and develops advantages in any of the boards, for example floorboards. For example, a significant advantage is that the front end region of the lower groove side can be used for additional fastening measures, for example by means of the clip 16 shown, or even by nail fastening, if the fourth contact point 8d is used to fix the position perpendicular to the surfaces of the plates, arranged on the inclined surface 3 of the tongue 3, or also on a straight but defined contact point 8b defined separately from the contact point on the lower side of the tongue.

As a further special feature of the embodiment of FIG. 8, the surface of the tongue 3 facing away from the face side has at least a slight recess at the transition between the region parallel to the plate surface and the contact point 8b and the inclined surface 30. 52 which separates the two contact areas. In other words, it is not necessary to connect the kink on the side of the tongue 3 facing away from the visible side to the respective kink on the side of the respective groove side. Rather, the contact must be realized only at the contact point 8b and between the two inclined surfaces 30, 32 in order to fix the two panels to each other in a defined position.

The placement of the next plate, as shown in FIG. 8 of the right-hand plate, is carried out only after the left-hand plate of FIG. 8 has been fixed to the substrate by means of one or more fastening clips 16. This fastening clip essentially corresponds to the fastening clips described above. A special feature of the embodiment of FIG. 8 is, however, that the plate according to the invention has no additional groove (20, cf. FIG. 2) on the side provided with the groove for receiving the fastening clip section 19. Rather, the height of the side of the groove facing away from the interior of the room is aligned in such a way with the free space 36 on the side of the (right) tongue plate facing away from the room to create a clearance or recess 38 for the fastening clip section 19. 40 of the groove side concerned and the opposite edge 42, there remains a suitable clearance space on the tongue plate 44, in which a fastening clamp 18 is attached which connects the section 19 to the fastening clamp base plate 16. namely, the free spaces 38, 44 formed in their joined state in the joining area of the two plates.

Figure 9 is a perspective view of the embodiment of Figure 8; This additionally results in the dimension of the fastening clip 16 in the direction of the joining edges of the two plates I to be considered. This dimension is relatively short, so that a plurality of such clips are usually used over one edge. By means of the apertures 46, the clip can be fixed to the support structure, for example by means of screws, so that a further plate, as shown in FIG. For fastening by means of a clamp, it should be noted that the subsequently laid plate, as shown in FIG. 9, is the left plate, which is movable in the direction of the connecting edges. In particular, the free space 38 is chosen such that the fastening clips used do not prevent such displacement. By means of this displacement, a further, third plate can be connected on the third and fourth sides (the previous examples only concerned the first and second sides).

Moreover, according to FIG. 8, the left plate 7 is positioned by means of the sections 18 and W of the clip 16 in such a way that the plate T can move relative to the clip in the direction of arrow A. This creates a floating fastening on the substrate or support structure. joining the plurality of joined panels relative to the clips 16 to move, and effects such as shrinking or swelling of the panels can be captured without the risk of the panels spacing apart on the face side. This effect applies in the same way to the embodiment according to FIGS. 2 to 5. In particular, in these embodiments, it is necessary to ensure that the cross-member 18 is sufficiently distant from the leading edge 40 of one groove side so that it is possible in all directions movement in the direction of arrow A. Movements in the order of a few millimeters can advantageously be permitted. In addition, in the embodiment of FIGS. 8 and 9, a recognizable central larger opening is provided as a longitudinal opening, so that possibly the buckle itself can be displaced somewhat on the support structure on which it is placed. Alternatively, the aforementioned advantages can be achieved by making the support or substructure itself movable. In other words, the connection between a plurality of plates according to the invention and the support or substructure would be rigid. However, the paneled area could work by:

The supporting or substructure, especially its slats or beams, are displaceable relative to the fixed part of the building.

The coupling described on the third and fourth sides is shown in the following figures. For the embodiment of FIG. 9, there are similarities to the embodiments of FIGS. 2, 3, 5 and 6, since the connection is essentially a linear translational movement. In particular, the rib 6, which is formed on the side of the tongue 5 which faces away from the room, is locked or snapped into engagement with the holding channel 6 which is formed on that side of the groove delimiting the groove 2 which is also oriented in the direction from inside the room. The peculiarity of the connection shown in FIG. 10 is that the tongue 3 is relatively short and protrudes only to a slight extent into the groove 2. The travel path required for locking is essentially determined by the distance A between the outer edge of the tongue 3 and the leading edge The front edge of the tongue 3 must be inserted along the front edge of the groove side of the already laid second plate. Only when this is done can the third plate of FIG. 10 be moved to the left in the right direction to assume the mounting state shown in FIG. 10. In the exemplary embodiment of FIG. 10, the length of the tongue 3 is substantially shortened to that dimension. However, a considerably shortened displacement path can also be realized in comparison with the known connections which can be connected by a flat insertion into one another, which ensures that even the last or highest wall-mounted plate can be connected to the boards already laid in such a way that a relatively slight gap remains with respect to the ceiling. In the exemplary embodiment of FIG. 10, it should also be noted that the groove base runs obliquely.

The same applies to the embodiment of FIG. 11, which differs from the embodiment of FIG. 10 in that, according to FIG.

The grooves facing away from the room extend further than the groove side from the room side and that there is a retaining channel in this region for receiving the rib 5

6. This is advantageous for certain applications and, moreover, the same advantages as those described above with respect to the exemplary embodiment of FIG. 10 are realized.

The embodiment of FIG. 12 differs from the embodiment of FIG. 11 in that both the rib 5 and the boundaries of the retaining channel 6 are made somewhat hook-shaped. A further peculiarity is that the recess 48 is connected to the actual groove 2, which serves to hold the tongue 3, which in this example has a smaller width (from top to bottom according to FIG. 12) than the groove 2. However, this is not absolutely necessary. . Rather, the depression 48 may have the same width as the groove 2 at least in certain sections and may be arbitrarily formed in the others. Cavity 48 with the lower edge of the groove to some extent, extends to the bottom prohioubeniny ^- 48 Na zákiaaě * of? Deišíhď proveciěnr may be Boice groove provided on a larger scale flexibility and the possible trajectory of the pen, giving particularly good qualities for vychyiování that are needed to allow the rib 5 to be inserted along the boundary of the retaining channel 6 so that a connection is established. In particular, in the embodiment of FIG. 12, there is less risk of cracks forming at the bottom of the groove 2 or recess 48.

This advantage also applies to the embodiment shown in FIG. 13. Also here, a recess 48 is connected to the groove 2, which leads to the advantages described. The design of the groove 2 and the tongue 3, moreover, correspond to the connection with the retaining channel 6 and the rib 5 of the exemplary embodiment shown in FIG. 10.

Finally, FIG. 14 shows an exemplary embodiment in which the newly laid sheet 1, shown left in FIG. 14, engages an already laid, right sheet according to FIG. 14, in a movement perpendicular to the surfaces of the sheets. In other words, the newly laid board is sloping on its first or second side

φ. The first plate is placed, and is then rotated, for example according to the connection shown in FIGS. 8 and 10. The fitting is carried out in such a way that the illustrated tongue 3 directed perpendicularly outwardly from the plates is oriented approximately with a groove 2 open to the plates surface. Upon lowering, the tongue 3 then moves into the position shown in FIG. 14 and is locked in a locking manner. This is realized by a mushroom-like design of the tongue 3, with an enlarged end, on which in particular a locking protrusion 5, corresponding to the rib described above, is formed. The latter is fastened in a suitable recess 20 on the groove 2. Also with this connection, illustrated in FIG. 14, a joint can be made in a reliable manner without joints of several plates on their third and fourth sides. Moreover, with reference to the exemplary embodiment of FIG. 14, WO 01/51732 A1 is fully disclosed.
