Abstract

The moisture-permeable tile laying mat (10) has a 1 millimeter thick moisture absorption layer (12), an upper side (14), a lower side and multiple recesses (18). The recesses extend from the upper side to the direction of the lower side. The moisture absorption layer is formed like woven fabric or fibrous web. The moisture absorption layer is formed of similarly or differently formed plastic threads, particularly polyester threads. An independent claim is included for a method for manufacturing a moisture-permeable tile laying mat.

Description

The present invention relates to a tile laying mat for laying tiles on a substrate. The term tiles is used below as a generic term for all hard coverings made of ceramic, natural stone or mineral bonded tiles and slabs as well as made of plastics or wood-based materials rigid lining material.

Tile laying mats of the aforementioned type are known in the prior art in different embodiments.

For example, the DE 37 01 414 A1 a tile laying mat with a plastic plate having a profile consisting of mutually parallel, alternating dovetailed webs and dovetailed grooves, and with a connected to the underside of the plastic plate attachment layer for securing the tile laying mat on a substrate, wherein the attachment layer is formed by a coarse-meshed nonwoven fabric , For laying tiles using this tile laying mat, the wall or floor surface to be covered with tiles is first coated with an adhesive or mortar layer. Then the tile laying mat is glued to the substrate with the aid of the coarse-mesh net fleece arranged on its underside. The directed to the ground side dovetailed grooves of the plastic plate, which are only partially filled with adhesive or mortar, form pressure equalization spaces that compensate in the finished floor joint between the substrate and the tiles occurring stresses and serve to dissipate moisture from the substrate or the adhesive - or mortar layer rises to tile laying mat. After attaching the tile laying mat on the substrate another adhesive or mortar layer is applied to the top of the plastic plate, wherein the adhesive or the mortar clamped in the open to the upper side of the plastic plate dovetailed grooves. In this way, a firm hold in the dried state of the adhesive or mortar generated between the plastic plate and the adhesive or mortar layer. After applying the adhesive or mortar layer tiles can now be laid on top of the tile laying mat.

With the DE 37 01 414 A1 Accordingly, a tile laying mat is provided which has both a decoupling and a drainage function. A major disadvantage of this tile laying mat is that although rising from below towards the tile laying mat moisture can be collected and removed in the pressure compensation chambers formed by the dovetailed grooves of the plastic plate directed to the ground side, but not moisture in the adhesive or mortar layer between the Tile laying mat and the tiles is present. This is particularly a problem when very large, moisture-impermeable tiles are used, so that a removal of moisture through the existing joints between the tiles is not sufficient. Accordingly, the adhesive between the tile laying mat and the tiles can not dry sufficiently, which may lead to the tiles peeling off, depending on the type of glue used or the temperature variations experienced by the composite.

Another tile laying mat is in the EP 1 712 695 A2 disclosed. This tile laying mat comprises a film-like plastic plate with respect to its top outstanding, load-bearing, hollow towards the bottom, arranged in a uniform surface distribution, partially undercut support elements, between the support elements open wasserabführende channels are formed. On the support elements, a water- and vapor-permeable non-woven or fabric-like cover is arranged. For laying tiles using this tile laying mat, the laying mat is embedded on the substrate over its entire surface in the area of its lower bearing surfaces in a still soft, thermosetting Dünnbettmörtelschicht, with the mortar anchored in the undercuts of the undercut trained support elements, creating a solid bond between the ground and the tile laying mat is produced. Subsequently, the ceramic plates are laid directly on a thin-bed mortar layer on the top of the tile laying mat arranged fleece-like cover and fixed, where the mortar is clamped to the fleece, so that the tiles are securely held on the tile laying mat. In this tile laying mat, moisture present in the thin-bed mortar layer disposed between the tile-laying mat and the tiles can pass through the non-woven or fabric-like cover into the drainage channels and be discharged therefrom. By contrast, moisture coming from below can not penetrate the film-like plastic plate, which is why removal of moisture from the substrate or from the thin-bed mortar layer arranged underneath the tile-laying mat is not possible.

Based on this prior art, it is an object of the present invention to provide a tile laying mat of alternative construction. In particular, a tile laying mat is to be provided which allows two-sided removal of moisture even when using large-area, moisture-impermeable tiles.

This object is achieved according to the present invention by a tile laying mat according to claim 1 and by a method for producing such a mat according to claim 19. The dependent claims relate to individual embodiments of the present invention.

The tile laying mat according to the present invention is a moisture-permeable mat, that is to say a mat which, when installed as intended, allows water in the liquid and / or vapor state to be passed both from above and from below. For receiving moisture entering the tile laying mat, it comprises a moisture-receiving layer having a thickness of at least 1 mm to ensure a sufficient moisture-absorbing volume. This moisture absorption layer is preferably not only moisture-permeable but also moisture-wicking and / or moisture-balancing. Accordingly, the moisture absorbed in it is evenly distributed and / or derived. In addition, the moisture absorption layer is preferably air-permeable and / or heat-insulating and / or sound-insulating.

The moisture-absorbing layer also has a plurality of recesses extending from the upper side toward the lower side. These recesses, which are preferably distributed evenly over the entire surface of the tile laying mat are filled in the laying of the tiles with adhesive or mortar, whereby Tragstelzen are formed, which absorb those forces and forward to the ground, which are applied to the tiles. These support stilts also prevent the moisture absorption volume provided by the moisture-receiving layer from being reduced due to forces acting on the tiles. So they serve as spacers, which counteract a compression of the moisture absorption layer and accordingly ensure the proper moisture absorption function of the tile laying mat.

If the tile laying mat is to perform a decoupling function in addition to its moisture absorption function, then it is important that the recesses do not penetrate the underside of the tile laying mat. The recesses must therefore not form through holes. Accordingly, it is prevented that the supporting stilts formed by the recesses connect with the adhesive or mortar layer arranged below the tile laying mat and a direct coupling is produced.

Furthermore, in order to achieve a decoupling function, it is advantageous if the load-bearing stilts can move within the recesses-possibly with displacement of adjacently arranged regions of the moisture absorption layer. In this way, for example, occurring between the substrate and the tiles shearing forces can be compensated, leading in the long term to a detachment of the tiles. For this purpose, the bottom and / or side walls of the recesses are advantageously at least partially formed such that there is no adhesive bond between them and a tile adhesive introduced into the recesses or the load-bearing stilts. Preferably, the bottom and / or side walls of the recesses are in the form of a smooth plastic surface which forms an adhesive bond between the bottom and / or side walls of the recesses and the tile adhesive prevented.

The moisture absorption layer is advantageously non-woven or fabric-like and has a corresponding elasticity. It preferably comprises the same or differently formed plastic threads, in particular polyester threads, which can be arranged regularly with a predetermined orientation and / or in the form of a fabric or irregularly as a tangle.

With the bottom and / or top of the moisture absorption layer is preferably a fastening layer connected, in particular glued. The underside or upper side of the attachment layer is preferably designed such that it forms an adhesive bond with a tile adhesive. In particular, the attachment layer may be formed for this purpose a fleece, tissue or lattice-like. In this case, the attachment layer should prevent too deep penetration of the adhesive into the moisture absorption layer in order not to impair the function of the moisture absorption layer.

The moisture-receiving layer is, in accordance with an embodiment of the present invention, a pile fabric layer of a spacer fabric disposed between a lower and an upper cover fabric layer. Such spacer fabrics are already known in the prior art in other contexts and are used in particular for the upholstery of objects, such as bicycle helmets, shoe soles or the like. They are mainly made of polyamides and polyester and offer a very good heat and moisture regulation due to the existing between the threads of such a knit cavities. These spacer fabrics can be produced in different thicknesses. For the present application, spacer fabrics having a thickness of 1 mm and more are preferred. The defined distance between the two cover textile layers of the spacer knitted fabric is normally achieved by the pressure-elastic threads (pile threads). The use of such spacer fabric as a carrier for ceramic plates thus ensures both a good drainage and thermal insulation function. Further, if desired, a decoupling function can be realized.

The underside of the lower cover textile layer and / or the upper side of the upper cover textile layer is / are, according to one embodiment of the present invention, non-woven in order to achieve a good adhesive bond between the underside of the lower cover textile layer and an adhesive. According to an alternative embodiment of the present invention is connected to the underside of the lower cover textile layer and / or with the upper side of the upper cover textile layer, a bonding layer, in particular glued, the underside / top or the outwardly facing side is formed such that it with a tile adhesive an adhesive bond for fixing the tile laying mat is received. In this case, the outwardly facing side of the attachment layer is advantageously formed like a fleece to achieve the desired adhesive bond.

The tile laying mat has a total thickness preferably in the range of 1-5 mm. Furthermore, it is advantageously designed so flexible that it can be rolled up. Of course, it can also have a greater thickness, for example, if a good air circulation in the attachment of tiles to wall or ceiling surfaces to be guaranteed.

Advantageously, the tile laying mat is designed so tear-resistant that it can be fastened to walls and ceilings with fastening means, in particular with dowels and screws.

In addition, the present invention provides a method for producing a tile laying mat of the type defined above.

Advantageously, the method includes the step of forming the recesses of the moisture-receiving layer by partially fusing at least the moisture-receiving layer, thereby producing smooth bottom and / or side walls that prevent adhesive bonding to a tile adhesive. The recesses are advantageously formed using hot stamping dies of a molding tool in the tile laying mat.

The FIGS. 1 to 3 show a tile laying mat 10 according to a first embodiment of the present invention, wherein the Figures 1 and 2 the tile laying mat 10 show itself, whereas the FIG. 3 in the Figures 1 and 2 illustrated tile laying mat 10 in the installed state represents. The tile laying mat 10, which may be plate, sheet or carpet-like, comprises a moisture-permeable, fleece-like moisture absorption layer 12. The moisture absorption layer 12 has a plurality of irregularly arranged in the manner of a tangle plastic threads, such as polyester threads, which are at least partially interconnected and Accordingly, create a coherent mat-like composite with a top 14 and a bottom 16. The moisture absorption layer Also includes a plurality of recesses 18 extending from the top 14 towards the bottom 16, but not piercing the latter. The recesses 18 have a circular cross-section, which tapers conically from top to bottom, whereby upside-down truncated cone shapes are formed. These recesses 18 are made by pressing hot punches of a die, the ends of which have a negative contour corresponding to the contours of the recesses 18, into the top 14 of the moisture-receiving layer 12, the plastic threads contacting the punches due to the high temperature come to be melted, so that the recesses 18 arise. Due to the melting process of the plastic threads, the recesses 18 receive a smooth bottom wall 20a and a smooth side wall 20b. The thickness d of the moisture absorption layer 12 or the tile laying mat 10 is in the present case 3 mm. In principle, however, the thickness can be in a range between 1 and 5 mm. If, for example, a floor structure with a low height is in the foreground, then a small thickness d is recommended. If, on the other hand, a good insulation function is of particular importance, it is advisable to choose a larger thickness d.

For laying tiles 22 on a substrate 24, which may be a floor or a wall surface, is on the substrate 24, as in FIG. 3 is shown, first applied a tile adhesive layer 26. Subsequently, the tile laying mat 10 is pressed onto the tile adhesive layer 26 with the underside 16 of the moisture receiving layer 12, tile adhesive partially penetrating the interstices between the plastic threads of the moisture receiving layer 12 and enclosing the plastic threads, so that the moisture receiving layer 12 over the tile adhesive layer after drying of the adhesive 26 is firmly connected to the substrate 24. Subsequently, a further tile adhesive layer 28 is applied to the upper side 14 of the moisture absorption layer 12. In this case, the tile adhesive penetrates partially into the nonwoven on the upper side 14 of the moisture absorption layer 12, whereby after drying of the tile adhesive also a firm bond between the tile adhesive layer 28 and the moisture absorption layer is generated. Further the tile adhesive 28 applied to the upper side 14 of the moisture-receiving layer 12 penetrates into the recesses 18 and fills them completely. Due to the smooth bottom and side walls 20a, 20b of the recesses 18, however, unlike the top 14, no strong bond is created between the tile adhesive and the walls 20a, 20b of the recesses 18. In a subsequent step, the tiles 22 can now be placed on the tile adhesive layer 28, in order in this way the in FIG. 3 finished floor composite 30 completed.

Due to the fact that the moisture-receiving layer 12 of the tile-laying mat 10 is moisture-permeable, moisture present in the substrate 24 and in the lower tile adhesive layer 28 may enter the moisture-receiving layer 12 through the upper surface 16 as well as moisture present in the upper tile adhesive layer 28 , Accordingly, the substrate 24 as well as the tile adhesive layers 26 and 28 can easily completely dry out and harden, whereby the extracted moisture is collected in the moisture absorption layer 12 and possibly removed by it.

The penetrating from above into the recesses 18 adhesive forms supporting stilts, which extend from the top 14 of the moisture receiving layer 12 in the direction of the bottom 16, the latter, however, do not break, with the support stilts compressing the underlying them fleece of the moisture absorption layer 12 against the ground Support 24 or tile adhesive 26. Accordingly, there is no direct connection between the upper adhesive layer 28 and the lower adhesive layer 26, so that the adhesive layers 26, 28 are decoupled from each other and thus the substrate 24 from the tiles 22. Due to the smooth bottom and side walls 20a, 20b of the recesses 18, the support stilts are also loosely received in the recesses 18, so they can move laterally with displacement of the adjacently arranged nonwoven moisture absorption layer 12. In this way, existing stresses between the substrate 24 and the tiles 22 can be compensated for and a loosening of the tiles 22 due to such stresses can be prevented.

Due to the fleece-like moisture absorption layer 12, a heat and impact sound insulation is also achieved.

FIG. 4 shows a cross-sectional view of a tile laying mat 40 according to a second embodiment of the present invention. The tile laying mat 40 comprises a moisture absorption layer 42 which is formed of plastic threads arranged transversely to each other. Thus, the moisture-receiving layer 42 comprises a regular, brush-like structure, which has a relatively high strength due to the orientation of the plastic threads. Accordingly, the moisture-receiving layer 42 is less likely to compress than, for example, the moisture-receiving layer 12 of FIG FIGS. 1 to 3 The tile laying mat 40 further comprises two attachment layers 44 and 46 of nonwoven, which receive the moisture absorbing layer 42 between them and are each glued to this. If tile adhesives are applied externally to these attachment layers 44 and 46, then they are at least partially clamped to the nonwoven, whereby a firm bond is produced between the adhesive layer and the corresponding attachment layer 44, 46 in the cured state of the tile adhesive. The tile laying mat 40 further comprises analogous to FIG. 1 a plurality of recesses 48 each extending through the upper attachment layer 46 and the moisture-receiving layer 42. On the other hand, the recesses 48 do not pass through the lower attachment layer 44. The recesses 48 are analogous to FIG. 1 regularly distributed over the entire top of the tile laying mat 40 and have a circular cross-section gradually tapers from the upper attachment layer 46 in the direction of the lower attachment layer 46, as in FIG. 4 can be seen. As well as the recesses 18 of the tile laying mat 10, the recesses 48 of the tile laying mat 40 smooth bottom walls 50a and smooth side walls 50b, whereby an adhesive bond between the walls 50a, 50b of the recesses 48 and a disposed in the recesses 48 tile adhesive is prevented.

Should now (analogous to FIG. 3 ) Tiles 22 on a substrate 24 below Use of the tile laying mat 40 are laid, where initially a tile adhesive layer 26 is applied to the substrate 24 again. Thereafter, the tile laying mat with the lower attachment layer 44 is pressed onto the tile adhesive layer 26, so that the tile adhesive at least partially penetrates into the fleece of the attachment layer 44 and surrounds it, so that in the cured state of the tile adhesive, a firm bond between the tile adhesive layer 26 and the attachment layer 44th is produced. Subsequently, a further tile adhesive layer 28 is applied to the top of the upper attachment layer 46 of the tile laying mat 40, wherein the tile adhesive partially penetrates into the web of the upper attachment layer 46 so that a correspondingly strong bond is also generated there. Furthermore, the tile adhesive penetrates into the recesses 48 of the tile laying mat 40 and fills them completely. Due to the smooth bottom and side walls 50a, 50b of the recesses 48, however, an adhesive bond between tile adhesive and the bottom and side walls 50a, 50b of the recesses 48 is prevented.

The drainage, decoupling and damping functions are analogous to that with reference to FIG FIG. 3 realized construction described.

FIG. 5 shows a cross-sectional view of a tile laying mat 60 according to a third embodiment of the present invention. The tile laying mat 60 includes a moisture-receiving layer 42 as previously described with reference to FIG FIG. 4 has been described. On the underside of the moisture-receiving layer 42, an intermediate layer 62 is further adhesively held. In the present case, this intermediate layer is a moisture-permeable woven fabric layer which does not adhere to adhesive bond with tile adhesive when it comes into contact with it. On the underside of the intermediate layer 62, in turn, a fastening layer 44 is fixed, as previously described with reference to the second embodiment. Furthermore, the tile laying mat 60 comprises a multiplicity of regularly distributed recesses 64 in an analogous manner FIG. 1 , These recesses 64 extend through the entire moisture absorption layer 42 and comprise a circular cross section which widens in the direction of the underside 16, starting from the upper side 14 of the moisture absorption layer 42, so that arise truncated cone shapes. Alternatively, for example, a truncated pyramidal formation or the like would be conceivable here as well. Correspondingly, the recesses 64, viewed from above, form undercuts in which tile adhesives introduced into the recesses 64 can be clamped. Thus, on the in FIG. 4 omitted upper attachment layer can be omitted. The recesses 64 also have smooth bottom and side walls 66a, 66b which, together with the intermediate layer 62, prevent sticking of tile adhesive within the recesses 64.

The drainage, decoupling and damping functions are analogous to that with reference to FIG FIG. 3 realized construction described.

FIG. 6 shows a cross-sectional view of a tile laying mat 70 according to a fourth embodiment of the present invention. The tile laying mat 70 includes a moisture-receiving layer 42 as previously described with reference to FIG FIG. 4 has been described. A woven upper cover textile layer 72 and a woven lower cover textile layer 74 are fixedly bonded to the upper surface 14 and the lower surface 16 of the moisture receiving layer 42, so that the moisture absorption layer 42 is sandwiched between the cover textile layers 72 and 74 in a knit-knitted manner to form a so-called pile layer. The tile laying mat 70 further includes a plurality of recesses 66 analogous to FIG. 1 extending through the upper cover textile layer 72 and the moisture-receiving layer 42. The recesses 76 are cylindrically shaped and comprise smooth bottom and side walls 78a, 78b, which do not form an adhesive bond with tile adhesive. Also, the woven fabric cover layers 72 and 74 do not bond with tile adhesive. For this reason, a fastening layer 44 is attached to the lower cover layer 74, as described with reference to FIG FIG. 4 has already been explained in order to be able to stick the tile laying mat 70 to a substrate using a tile adhesive. Further, a mounting grid is glued to the upper decktextilschicht 72, the mesh width is so large that applied to the tile laying mat 70 tile adhesive easily penetrate the mounting grid 80 and fill the recesses 76. This mounting grid 80 provides a firm adhesive bond between the Tile adhesive and the top of the tile laying mat 70 in order to produce in this way a proper floor joint can.

The drainage, decoupling and damping functions are analogous to that with reference to FIG FIG. 3 realized construction described.

The moisture-absorbing layers 12 and 42 of the tile-laying mats 10, 40, 60 and 70 of the embodiments described above are not only moisture-permeable but also moisture-wicking and moisture-compensating. In addition, they are permeable to air, heat-insulating and soundproofing.

It should be understood that the embodiments described above are by way of example only and are not intended to be limiting in any way. In particular, it should be noted that it is only necessary to achieve the decoupling effect that the bottom walls of the recesses do not form an adhesive bond with the tile adhesive. The side walls of the recesses can accordingly also have a rough surface without the decoupling effect being significantly impaired. Also, both the bottom and the side walls of the recesses may have a rough surface, so that they enter into an adhesive bond with the tile adhesive entering the recesses. However, this is at the expense of the decoupling effect of the tile laying mat, which is why at least smooth bottom walls are preferred. Further, it should be understood that the moisture-receiving layers of the individual tile-laying mats may include not only plastic threads but also natural-material threads, metal threads, metal-sheathed metal threads, or the like. Also, combinations of filaments of different shapes and materials, such as open-cell foamed material, are possible. In addition, the recesses may have any cross-sectional shapes, such as polygonal, round or oval cross sections. Furthermore, the rigidity of the tile laying mat according to the invention in thickness direction is preferably selected such that the tile laying mat can at least absorb the weight of the adhesive layer arranged above it and the tiles, without any significant compression in Thickness direction to learn. Accordingly, the cavity provided by the moisture-receiving layer for absorbing moisture is prevented from being reduced during the drying of the adhesive due to the self-weight of the adhesive layer and the tiles. After the adhesive has dried, the support stilts prevent compression of the moisture-receiving layer.

By the term "adhesive" is meant all for the attachment of the tile laying mat and / or the attachment of the respective designated as tiles hard coverings suitable adhesives or mortars.
