Abstract

The floor panel has a base plate (13) and a cover plate (2). The base plate has a connecting tongue (8,9) on one long (3) or small edge and a corresponding groove (7,10) on one of two other sides. The cover plate is made of synthetic or natural stone. The tongue and groove on the longer sides can have locking formations (11,12). The tongue and groove connections on the smaller edges are perpendicular to the laying direction of the panels.

Description

The invention relates to a floorboard with the features of the claim 1.

Floorboards, especially parquet floorboards, consist of a cover plate made of hardwood, and a single-layered or multi-layered structure Base plate, in particular made of MDF / HDF and a return from Softwood.

Such a floorboard has on one longitudinal side and on one Narrow side one continuous clutch spring and the other Longitudinal side adapted to the cross section of the clutch springs Kupplungsnuten on.

In the prior art are a variety of different Kupplungsfeder- and Kupplungsnutenkonfigurationen known, especially those with which Floorboards both on their long sides as well as on their narrow sides gap-free and glueless tensile and pressure resistant joined. These so-called Click systems (e.g., DE 297 10 175 U1, DE 199 25 248 C2) have been incorporated Parquet and laminate flooring are very well proven and allow a craftsmanship easy and quick installation.

Other than interconnectable wooden floorboards require Floor coverings made of ceramic or natural stone a much higher Laying costs. This is partly due to the fact that ceramic or Natural stone floor coverings are used where high abrasion resistance and good wet cleaning properties are required. Flooring made of tiles or natural stone are at the latest after the professional grouting in the Normally no longer destructively removable or reusable. A Reusability of a high quality mineral flooring can be however, may be desirable in certain applications, such as at the fair construction.

On this basis, the invention is based on the object, an abrasion-resistant Show floor flooring, with which a quick and easy installation a flooring is possible, and in addition a non-destructive Dismantling and reusability allows.

This object is achieved by a floorboard with the characteristics of Patent claim solved. The claimed floorboard comprises a Base plate and a cover plate, wherein the cover plate of artificially manufactured or natural stone. Natural stone in the context of the invention preferably marble. Artificially made stone can be made of mineral Materials produced panels, for example, natural stone components contain. Under artificially produced stone are also ceramic tiles or to understand plates configured as a cover plate with the base plate are connected.

The mineral cover plate is at its peripheral longitudinal edges in essentially smoothly configured and does not itself contribute to a positive fit Connection with adjacent floorboards at. This function takes over the base plate, which at a first longitudinal side and at a first Narrow side a clutch spring and on the other second long side as well the other second narrow side to the cross section of the corresponding Having clutch springs adapted coupling grooves. The clutch springs and coupling grooves can on the respective longitudinal sides and Narrow pages be designed consistently. For a composite of the individual Floorboards can both the clutch springs of the first longitudinal side and the first narrow side be uniform and then with the also fit uniformly shaped coupling grooves. It is in However, the scope of the invention also possible that the coupling grooves and - Feathers of the long sides differ from those of the narrow sides.

In an advantageous embodiment of the inventive concept are on the clutch springs and coupling grooves of the longitudinal sides locking means formed, which in flooring in a floor covering adjacent floorboards reach each other in locking engagement (claim 2). In particular can pre-stored the coupling grooves limited resilient locking tongues be, which can be joined with locking grooves below the clutch spring. About the clutch springs, clutch grooves and locking tongues can Floor boards along their long sides joined gap-free tensile and pressure resistant become. In particular, the floorboards can at least at their Long sides are connected to each other via so-called click systems.

An essential advantage of the so-called click systems over conventional ones Tongue and groove systems is that the individual floorboards without great effort and especially without punches with a hammer or similar to one another shock-free sliding into each other with each other slidably are, especially in shock-sensitive materials such as mineral Cover plates (e.g., marble) are of particular advantage.

So after joining two floorboards on their long sides no force needs to be exerted on the narrow sides to face these another latching floorboard, it is according to the characteristics of Patent claim 3 provided that the clutch springs of the first Narrow side and the coupling groove of the second narrow side perpendicular to Laying level run. That means that especially at a Swiveling a second floorboard in the longitudinal coupling groove an already laid floorboard the narrow side of the to be laid Floorboard in a sense from above without additional effort in swung in the adjacent narrow side of an already laid floorboard can be. In addition to the swinging it is at designed clutch springs and clutch grooves of the long sides also possible, a floorboard first with the narrow side of an already partially relocated laid floorboard and then by sliding in Direction of the laying level in the longitudinal side of a likewise already laid introduce further floorboard and lock. To get stuck in To avoid the coupling groove of the narrow side, it is expedient to Form the coupling elements of the narrow side with play.

According to the features of claim 4, the coupling groove of second narrow side facing away from the cover plate undercut formed on the underside of the base plate, wherein the clutch spring of first narrow side towards the cover plate pointing to one the undercut Undergrated tongue is formed with play in the Clutch groove holds.

In particular, when the side walls of the coupling groove and the clutch spring are formed parallel to each other (claim 5) is on the one hand a mutual Verkrallung guaranteed in the laying direction and an exact Relocation, their goodness to a lesser extent from the game between Clutch spring and coupling groove is dependent.

While the individual base plates at least in the area of their long sides be laid without gaps, it has proved to be advantageous if between the cover plates of adjacent floorboards of a floor covering a up to the base plate projecting joint remains (claim 6). On the one hand can in this way manufacturing tolerances of the cover plate on the other hand are joints in mineral floor coverings aesthetically pleasing to the human eye. Fugues between the Cover plates also simplify the laying of the floorboard, if this due to the design of the clutch springs and clutch grooves for Locking must be swung into each other. The fugue puts in this Case is a required clearance.

A flooring produced with the floorboards according to the invention Can easily be picked up and dismantled after installation become. For this purpose, the floorboards are reversed again separated and can, for example, at a change of residence taken away and relocated again in a new apartment. in the The floating installation is the responsibility of the user of course also possible to joints with suitable fillers too close if longer-term or permanent laying of floorboards is desired.

Unlike laying ceramic tiles, this is Joint dimension due to the exact dimensioning of the cover plates and the base plates exactly given, so that even without great craftsmanship Floor be made of artificially made or natural stone May be related to a floor covering made of tiles, slabs or natural stone the properties of the cover plates in no way inferior. In particular, you can Of course, the joints are sealed with waterproof filler, so that Such a floor covering can also be used in damp rooms. The key difference, however, is that due to the floating Laying a non-destructive disassembly of the flooring is possible where only the adhesive forces of the filler in the region of the joint must be overcome and excess grout removed must become. The floorboard itself is preserved.

According to the features of claim 7, the base plate with the Glued cover plate. The adhesive bond between cover plate and base plate is manufacturing technology particularly low feasible.

Advantageously, in the bottom of the cover plate and / or in the top of the Base plate provided a plurality of wells (claim 8). The Recesses are used in particular for receiving the between the base plate and the cover plate brought adhesive. Through recesses in the cover plate and / or the base plate becomes the surface of the facing sides increased, whereby the adhesive tensile strength of the cover plate over the Base plate can be increased. The depressions can be uniform or be arranged unevenly with constant or from each other different geometry, e.g. in the form of grooves or blind holes. the goal is it, a uniformly adherent support layer between the cover plate and the Form base plate.

To remove bumps between the facing surfaces of the Base plate and the cover plate can compensate, according to the characteristics of claim 9, a leveling layer between the base plate and the Cover plate may be arranged, which may be formed by the adhesive itself can be as well by other shape-flexible materials. These can do that Adhesive added or embedded in this.

Claim 10 proposes, as leveling layer, a fiber mat, e.g. a fiberglass mat to introduce. This fiber mat can be used on both sides Be provided adhesive and in this way the bond between the base plate and make cover plate. But it is also possible that the fiber mat completely permeated by the adhesive and that thus the base plate and the cover plate are glued directly to each other, wherein the leveling layer as Fillers and binders is to be understood.

Depending on the adhesive used can already by the leveling layer or the adhesive a certain footfall sound insulation within the floorboard itself, i. between the base plate and the cover plate. But it is also possible that insulating a footfall sound at the bottom of the base plate Coating is arranged (claim 11). Impact sound insulating Coatings can be glued over the entire surface as a sound-damping layer and can be made of a composite material with a low elastic modulus consist. Also slots in the bottom of the base plate have a footfall sound insulating effect.

As it is considered particularly favorable if the base plate made of wood or a wood material consists (claim 12). Wood materials, ie plates or molded parts consisting of several layers of wood (plywood), wood shavings (Chipboard) or wood fibers (wood fiber boards), which glues with glue are, consist, have a uniform composition, work less than Solid wood and are usually cheaper to produce. In combination with Decking made of artificially made or natural stone is called it considered useful if the wood material is waterproof, i. in particular Made of waterproof glued MDF / HDF panels or made of waterproof Plywood (claim 13). Instead of a single-layer base plate Multi-layered base plates can be used.

In addition to the material wood, it is also possible, the base plate made of molded materials cellulose-based or even of suitable plastics (Claim 14).

The bonding of a comparatively thin cover plate made of artificial made or natural stone allows a relatively high load of Cover plate, without this breaks. This is due to the fact that each single cover plate due to the joints on the adjacent cover plates a base plate of comparatively yielding material is stored and strong loads without breaking yielding resiliently. The load values of a flooring produced in this way are from a Variety of parameters dependent, of course, the geometric dimensions are of particular importance. But also the choice of material of the cover plate and the base plate or between Base plate and cover plate arranged leveling layer and the adhesive have a significant impact. Of course, the load capacity depends also from the shape of the underground. While a screed as optimal Underground is to see the floorboard according to the invention Of course, on a wooden or stone floor or even one Carpet be laid without this would have to be removed beforehand or extensive structural measures would be required. In particular No glue or mortar required to make a floor out of the invention to lay artificial or natural stone. Joints do not need necessarily to be completed. The joint distance is exactly through the Base plate defined. A clean and even laying is in everyone Case guaranteed. The upper peripheral edges of the cover plate can be slightly beveled like tiles. The chamfer can be between 1 and 3 mm be. The joint may have a width of less than 1 mm.

Figure 1 shows a single floorboard 1 in the direction of its mineral Cover plate 2. The floorboard 1 is rectangular configured with a first longitudinal side 3 and a second longitudinal side 4 and with opposite Narrow sides 5, 6. The first longitudinal side 3 and the first narrow side 5 is provided with a clutch spring 8, 9, the coupling grooves 7, 10 at the second longitudinal side 4 and second narrow side 6 is adjusted.

From Figures 2 to 5, the structure of the floorboard 1 in laying level clear. From Figure 2 it can be seen that the parquet board 1 at its first Long side 4 has a continuous coupling groove 7, which limits one resilient detent tongue 11 is upstream, with a locking groove 12 below the Clutch spring 9 can be joined. About the clutch spring 9, Kupplungsnut 7, and latching tongue 11, the floorboards 1 at their Long sides 3, 4 gap-free and glueless tensile and pressure resistant joined.

The entire aforementioned coupling arrangement is one edge Base plate 13 is formed, on which the mineral cover plate 2 via a Leveling layer 14 is adhesively bonded. The compensation layer 14 is in This embodiment, a glass fiber mat between the bottom 15 of the cover plate 2 and the top 16 of the base plate 13 of adhesive interspersed is introduced.

On the bottom 17 of the base plate 13 is a footfall sound insulating Coating 18 attached. The base plate 13 and the cover plate 2 have in this embodiment about the same thickness, while the leveling layer 14 and the impact sound insulating coating 18 a contrast have smaller thickness.

The embodiment of Figure 3 shows two adjacent floorboards. 1 in the region of their mutually facing narrow sides 5, 6. In contrast to the clutch spring 9 and the coupling groove 7 on the longitudinal sides 3, 4 are the Clutch spring 8 and the coupling groove 10 on the narrow sides 5, 6 not in the level of the flooring produced from the floorboards 1 oriented, but perpendicular to it. That the clutch spring 8 points in Direction to the cover plate 2, while the coupling groove 10 to the bottom 17 of the Base plate 13 has. The clutch spring 8 is formed on a tongue 19 and by an undercut 20 for receiving a coupling groove 10th delimiting web 21 spaced from the cover plate 2. Like FIG. 4 clarified, the tongue 19 holds in the assembled state in one of the Coupling groove 10 and the web 21 formed undercut 22 at the Bottom 17 of the base plate 13, wherein the clutch spring 8 of the first Narrow side 5 in the direction of the cover plate 2 pointing in the coupling groove 10th summarizes. At the same time, the web 21 engages in the undercut 20 at the first Narrow side 5 of the floorboard 1. In the illustrated configuration are the Side walls 23, 24 of the coupling groove 10 and the side walls 25, 26 of the Clutch spring 8 parallel to each other. The assembly is simplified by that the coupling groove 10 is slightly wider than the clutch spring 8. D.h. the Clutch spring 8 engages with play in the coupling groove 10 a.

From Figure 4 is further seen that between the cover plates 2, a joint 27 is present, from the top 28 of the cover plate 2 to the Top 16 of the base plate 13 protrudes. In this embodiment, the Cover plate 2 of the first narrow side 5 flush with the undercut 20 formed during the cover plate 2 in the region of the second narrow side. 6 opposite the web 21 is set back to the joint width.

The embodiment of FIG. 5 differs from that of FIG. 4 in that in the top 16 of the base plate 13 recesses 29 in shape introduced by regularly spaced grooves of rectangular cross-section are, which are filled by the compensating layer 14 forming adhesive.

Furthermore, the mutually facing upper edges 30, 31 of the narrow sides 5, 6 each provided with a chamfer 32, 33. The bottom 17 of the base plate 13 is as in the embodiment of Figure 2 with a footfall sound glued to insulating coating 18.
