Description

decoupling membrane

The invention relates to a decoupling web with a carrier plate and a plurality of projecting from the carrier plate plane nubs.

The term "decoupling" is understood in the present application, the reduction of shear stresses or stress peaks between two arranged in a solid composite layers. An effective decoupling thus prevents existing shear stresses or stress peaks in one of the layers from transferring to the other layer of the composite structure and causing damage there.

Decoupling tracks of the aforementioned type are used, for example, in the construction industry when laying floors, in particular for decoupling, sealing and / or for equalizing the pressure of vapor. The decoupling webs are laid on a substrate, in particular glued, and form the support surface for flooring elements, such as ceramic tiles. The laying of tiles is done especially on young screed in the thin bed process. If no decoupling web is laid between the tile floor and the young screed, the tiles, especially due to their low expansion coefficient, could not follow the movement of the screed so that shear stresses develop which ultimately lead to detachment or even tearing the tiles can lead. Even when laying coverings on especially critical substrates, such as old wooden floors, decoupling sheets are required. A decoupling web of the aforementioned type compensates for these shear stresses by deformation, which is why damage to the composite structure is not to be feared. Most decoupling tracks are made of foil-like plastic, ie of a flexible plastic layer, which deforms under the influence of external forces. The material is usually selected so that it is low in emissions, especially in terms of pollutants.

To fix the floor covering elements on the decoupling web, a thin layer of a tile adhesive, also called adhesive mortar or bonding layer, is usually applied to the support plane of the decoupling web. It goes without saying that, instead of a tile adhesive, ultimately an equally suitable adhesive or fastening layer or a corresponding material can also be provided. Tile adhesives are usually used with a toothed spatula or a toothed trowel combed and it is used depending on the application area and / or subsurface a different tile adhesive. For example, a reaction resin adhesive, a cementitious thin-bed mortar, a casein tile adhesive or a dispersion adhesive is used as the tile adhesive.

After applying the tile adhesive to a decoupling membrane, the individual flooring elements or tiles are laid on the tile adhesive. The tile adhesive penetrates into the depressions of the decoupling web during application and hardens.

In such decoupling webs, the associated flooring elements are separated from the substrate and mechanically decoupled. Due to the arrangement of the nubs transversely to the longitudinal direction and in the longitudinal direction of the carrier plate resulting channels that extend over the entire support plate. These channels act together with the nubs in such a way that they absorb and compensate for mechanical stresses and in particular shear stresses. This stress on the floor covering elements can be generated due to temperature and humidity influences and / or by a load with weight.

In the production of such decoupling webs, a mold is used which has projections corresponding to the depressions or nubs. The demoulding of mold and decoupling web is usually problematic. In addition, the decoupling web can be easily damaged during demolding, especially if the protrusions of the tool have sharp corners that cut and / or rip into the mostly soft decoupling web material. The latter problem is attempted to be solved in practice by providing the corners of the tool projections with a radius.

Decoupling tracks of the aforementioned type are known, for example, from EP 2 372 041 B1 and from EP 2 246 467 B1.

EP 2 372 041 B1 relates to a method for producing a carrier plate and to a carrier plate for a plate-clad floor, wall or ceiling structure for achieving a decoupling between the substrate and the surface covering to be applied to the foil-like plate, which comprises a foil-like plate having a plurality of Has chambers through depressions from a plane of the are formed film-like plate whose end faces form a first plate side and opposite a second plate side. In this case, at least on one side of the sheet, an adhesion-promoting layer of a sheet-like material is applied, which lines at least the depressions of the chambers. The adhesion-promoting layer should serve for better decoupling and, moreover, for better bonding of the tile adhesive. The depressions serve to receive the tile adhesive, which is applied on the top side to the adhesion-promoting layer of the decoupling web. In the known decoupling path, round, cylindrical and / or pot-shaped formations are provided as recesses.

Instead of an adhesion-promoting layer or in addition to this, it is known from EP 2 246 467 B1 that an improved adhesion of the tile adhesive should be made possible by application of a multiplicity of fibers to the upper side of the decoupling web which faces the tile adhesive. The nubs or recesses of this known decoupling web have a round, cylindrical and / or cup-shaped form and are accordingly rounded. The fibers deposited on the upper surface of the decoupling web are permanently connected to this surface. The tile adhesive is in this case introduced into the recesses of the carrier plate.

The decoupling webs known from EP 2 372 041 B1 and EP 2 246 467 B1 have regularly arranged round, cylindrical formations which are arranged in rows and columns. As a result of the arrangement, channels are formed between the rows of nubs which extend over the entire decoupling path. These channels are open to the ground and intersect with other channels. When applying the tile adhesive, the channels are only covered with a thin layer of tile adhesive so that they form a line of weakness that promotes deformation of the decoupling path along this line of weakness. In an unfavorable arrangement, the joint profile of adjacent covering elements would coincide with a weakening line or predetermined breaking point, so that hairline cracks and / or greater damage in the adhesive mortar layer and / or in the joint itself arise.

A disadvantage of the known decoupling trajectories is that they have no decoupling properties between the cladding elements to the substrate without the use of the additional adhesion-promoting layer or without additional fibers. The preparation is complicated in such Entkopplungsbahnen because to increase the adhesion between the tile adhesive and the Surface of the decoupling web, which faces the tile adhesive layer, an additional process step is provided by the application of the adhesion-promoting layer or additional fibers. The object of the present invention is therefore to provide a decoupling web which achieves an improved clawing of the tile adhesive with the decoupling web.

Moreover, it is in particular the object of the present invention to provide a simple and efficient method for producing a decoupling web.

The above object is achieved according to the invention in a decoupling web of the aforementioned type essentially in that a plurality of protrusions and / or depressions is provided on the side of the knobbin floor facing at least one knob, and / or that on the stud interior Side of the support plate, a plurality of projections and / or recesses is provided. The structuring and / or depressions and / or projections of the stud bottom and / or the support plate preferably have a height and / or a depth of greater than 1 μm, preferably greater than 100 μm, more preferably between 100 and 1000 μm, and in particular at least substantially between 300 to 500 μιη on. If a projection directly adjoins a recess, wherein the projection protrudes from the plane of the stud bottom and / or the carrier plate and the recess protrudes into the stud bottom and / or into the carrier plate, the distance between the deepest point of the recess and the highest is Position of the projection preferably greater than 50 μιη, more preferably greater than 100 μιη, more preferably further between 100 to 300 μιη and in particular at least substantially between 300 to 800 μιη.

In a further advantageous embodiment of the inventive concept, it is provided that the projections and / or depressions on the knobbed bottom and / or on the carrier plate form a structured surface of the knobbed bottom and / or the carrier plate.

Preferably, more than 20, preferably more than 100, more preferably more than 1000, preferably more than 10000, projections and / or depressions on the Stud bottom and / or the support plate provided, wherein the projections and / or depressions, preferably both on the stud bottom and on the support plate, are arranged irregularly and / or disorderly. A high number of protrusions and depressions results in a structured surface of the decoupling web.

In this context, a great variety of shapes and / or structures of the depressions and / or projections are advantageously provided, in particular wherein the shapes and / or structures of the projections and / or depressions result from the production method of the projections and / or depressions.

Ultimately, it is preferably provided according to the invention that a structured surface is formed for better engagement of the tile adhesive, resulting in a structuring of the surface due to projections and / or depressions. In this case, as explained below, the projections and / or recesses have a fixed geometric shape, in particular if they are embossed in the production of the decoupling web, and / or they have a variety of structures or forms, wherein it is essential to the invention that the projections and / or recesses have a maximum height and / or depth of greater than 1 μιη.

In a further preferred embodiment, a formation is performed to form an undercut on the projections and / or depressions. This shaping forms the undercut, in particular wherein the undercut serves for better engagement of the tile adhesive on the surface of the carrier plate and / or the stud bottom, the tile adhesive preferably engaging in the region of the undercut and digging there.

In a structuring of the stud bottom and / or the carrier plate, it is advantageously provided that at least 30% of the free surface of the stud bottom and / or the carrier plate are structured and / or have depressions and / or projections. Preferably, over 50% of the carrier plate and / or over 50%, preferably over 70%, more preferably 80% +/- 5%, of the entire surface of all dimpled bottoms are structured and / or have protrusions and / or depressions. This structured surface provides a better cleavage of the tile adhesive and an increase in the adhesive strength of the entire decoupling web. Preferably, the surface of the support plate and / or the dimpled floors is roughened or structured over the entire surface. As a result, it is provided that a plurality of projecting protrusions, between each of which recesses are provided, are provided on the knobbed base and / or the carrier plate, which serve for clawing / connecting with the tile adhesive to be applied to the decoupling sheet. These projections are ultimately material overhangs or elevations. The depressions are not perforations in the stud bottom or the carrier plate, which allow an exchange of air or moisture from the bottom side to the tile side. The same applies to the projections, which also have no openings or openings and therefore also do not allow air or moisture exchange from the bottom side to the tile side.

The aforementioned embodiment of the invention enlarges the exposed surface of the dimpled floors and the surface of the carrier plate facing away from the dimpled floors, ie. H. the surface of the webs provided on the carrier plate between the individual nub openings projecting into the nub interior spaces. By the projections and / or depressions and the surface thus increased results in an improved clawing of the tile adhesive. The protrusions and / or depressions according to the invention also improve the releasability of the entire decoupling web. The projections and / or recesses lead in particular to the decoupling web having increased flexural rigidity and / or torsional rigidity. In connection with the realization of the invention, it was found in tests carried out that the projections and / or depressions in the studded bottom and / or in the carrier plate improved bond strength by up to 40% in comparison with the known decoupling web-consequently a markedly improved Clawing the tile adhesive with the decoupling web - results.

The above-mentioned realization of the projections and / or the depressions and / or the structured surface of the carrier plate and / or the studded bottom can basically be realized on each studded bottom and / or stud in the manner described above, independently of the type of Configuration of the knob and / or the studded bottom. The nub can thus - seen in plan view - for example, an elliptical, in particular round, or even a square, in particular rectangular and / or square shape, have. Preferably, adjacent knobs are arranged transversely to the longitudinal direction of the carrier plate and in the longitudinal direction of the carrier plate, in particular in a row form.

In a particularly advantageous embodiment, it is provided that the nub is formed mehrschenklig. The multi-limbed design of the nub in combination with the arrangement of adjacent nubs transversely to the longitudinal direction of the carrier plate and in the longitudinal direction of the carrier plate in particular allows an optimal distribution between the exposed surface of the carrier plate and the nub surface. This ratio significantly determines the drainage and decoupling properties. In a multi-limbed formation of the knob, it was found in the experiments carried out that the decoupling properties can be improved many times over. Preferably, a plurality of projections and / or recesses is provided on the leg base of a leg.

Furthermore, in an advantageous embodiment of the inventive concept, an arrangement of immediately adjacent knobs is provided transversely to the longitudinal direction and in the longitudinal direction of the carrier plate, wherein immediately adjacent knobs have a three-axis knobbed bottom, in particular with at least three leg sides.

Under a three-axis design of the studded floor is a three-legged training in a two-dimensional extent to understand. The studded bottom or nub accordingly has three legs. For three-dimensional design of the knob is provided that adjoins the stud bottom at least one side wall to form the nub interior. The three-axis knob shape results in the plan view of the decoupling track.

First of all, the three-axis design of the dimpled base is characterized by the fact that a simple production of the decoupling web according to the invention is ensured. This production makes it possible in particular that high processing speeds are achieved, preferably by a so-called inline method, wherein the decoupling web is produced continuously with a comparatively high production speed. The increased te production speed is made possible in particular by the fact that a quick and easy demolding of the decoupling web according to the invention is provided. An increased processing speed leads in particular to a reduction of the production time and thus to a reduction of the production costs.

The nubs according to the invention and the nub device according to the invention also offer the possibility of a simple Ausespachteins the decoupling web with tile adhesive. This troweling is particularly simplified by the fact that a three-axis shape of the knobs is selected, so that the tile adhesive within this knob shape during application and introduction into the knobs well distributed and the air can escape well from the wells.

In addition, a good drying and a very good vapor pressure equalization is ensured because in the decoupling web according to the invention, the channels, which result between adjacent knobs, are connected to one another indirectly and / or directly over the entire dimpled sheet. Due to the three-axis knob shape of the dimpled bottom, the channels are preferably rounded or wavy, so that a full-surface vapor pressure equalization results without interruptions both good dehumidification and ventilation. Due to the inventive design of the decoupling web, the decoupling web can be applied in particular to a moist and possibly not fully cured substrate, in particular by the very good balance of vapor pressure trapped without the moisture contained in the ground and / or prevents the desired drying of the substrate and / or is delayed excessively. Consequently, the decoupling web can be installed promptly after production of the substrate. This results in particular in the advantage that the laying time of the entire floor covering can be drastically reduced, a quick work sequence is ensured and, accordingly, the production costs of the covering are reduced.

Furthermore, the dimpled sheet according to the invention has improved decoupling properties, since with a three-axis knobbly shape of the dimpled base, preferably in conjunction with the alignment of the knobs in rows in the longitudinal direction and transversely to the longitudinal direction of the carrier plate, with a central region defined by a circle, gives an improved load distribution. In addition, voltage spikes are reduced or partially completely avoided. The shear stresses are transferred to the decoupling track and distribute in particular on the surface facing away from the knobs surface of the support plate. The significantly improved load distribution is additionally advantageously achieved by the channel structure. The decoupling effect is advantageously configured such that, on the one hand, there are no cracks in the surface of the covering facing away from the decoupling track and, on the other hand, that possible cracks in the substrate, which occur in particular only after the decoupling track has been laid, do not occur in the tile adhesive layer and / or Mark on the flooring elements. In experiments carried out it was found that in comparison with the known from the prior art decoupling web using the triangular knobbed bottom knob the decoupling properties could be improved by up to 30%. In addition to significantly improved mold removal and increased decoupling properties, the studded mold according to the invention also offers greater tile adhesion strength, since the tile adhesive distributes itself very well in the depression caused by the cavity and in the depressions between the projections and interacts with one another the support plate and the knob leads to the fact that the strength is increased. This also increases the adhesive tensile strength of the entire decoupling web. Above all, no additional adhesion-promoting layer or additional fibers is required, so that in particular the production costs and / or the production time can be reduced.

The adhesive tensile strength serves as a parameter for the adhesion and / or adhesion of layers to substrates, in particular concrete surfaces. It is determined by means of a special test, which is also called adhesion test and / or tear test. DIN EN 1348 specifies a guideline for the determination of the adhesive tensile strength under defined conditions.

Due to the increased strength of the tile bonding and the improved decoupling properties, a lower overall layer construction height of the decoupling webs according to the invention can be selected in comparison to the decoupling web known from the prior art. This lower overall layer structure leads inter alia to the fact that less tile adhesive is required for the connection of the covering elements with the decoupling web during laying, so that there is a reduction in the manufacturing cost of the flooring to be laid.

The decoupling web according to the invention also has a high torsional rigidity, preferably when obtaining a high ability to wind. The high torsional stiffness or torsional stiffness requires that the decoupling web can not buckle and / or twist, in particular by 90 °. The winding ability nevertheless obtained implies that the decoupling web, preferably for transport, can be rolled up.

In a further embodiment, it is provided that the decoupling web has a low torsional stiffness, so that the decoupling web can bend and / or twist in particular. Preferably, in this embodiment, a rectangular shape of the knob is selected.

In addition, it was found in experiments carried out that the decoupling web according to the invention, in addition to their excellent decoupling properties also has a very good impact sound insulation. This effect is also the result of the special knob shape and arrangement.

In a particularly advantageous embodiment, it is provided that the projection and / or depression on the knobbed bottom is formed spirally and / or arc-section-shaped. It has been found that, in particular, the helical and / or rounded projection and / or recess shape results in improved clipping of the tile adhesive. Finally, it has been found in tests that it is particularly advantageous if the spiral projection and / or recess is provided in the central region of the stud bottom.

Incidentally, it goes without saying that a large number of projections and / or depressions may be provided on the dimpled base, so that the adhesive tensile strength between the decoupling web and the covering elements is increased.

Accordingly, it is provided in another preferred embodiment in connection with the three-legged knob or knob having the three-legged knobbed bottom that the leg base of a leg of the knob has a plurality of projections and / or depressions. In another preferred embodiment of the invention, the projections and / or depressions are arranged concentrically to the central region and / or to the center of the nub on the leg base. Furthermore, it has been found that it is particularly advantageous if the projections and / or depressions of the dimpled base are designed web-like and / or rectangular and / or elliptical in another embodiment. In this context, it is particularly preferred if the web-like and / or rectangular and / or elliptical projections and / or depressions are aligned on the stud bottom transversely and / or longitudinally of the longitudinal direction of the carrier plate. This arrangement of the projections and / or depressions on the dimpled base, in particular, results in a good releasability of the dimpled sheet by simply filling the decoupling sheet with the tile adhesive.

It is understood that not only projections and / or depressions may be applied to the studded bottom, but in a further preferred embodiment are alternatively to the projections and / or depressions on the stud bottom or in addition also projections and / or depressions on the support plate or ., the carrier plate webs between the protruding into the Noppeninnen- space Noppenöffnungen provided, both in the longitudinal direction of the support plate and in the transverse direction of the support plate. This arrangement of the projections and / or recesses on the support plate, in particular in combination with a preferred embodiment of the projections in ridge-like and / or rectangular and / or elliptical shape, requires good bond strength.

In addition, in another preferred embodiment of the invention, it is provided that the projections and / or depressions of the carrier plate are elongated and aligned with their longitudinal extent exclusively transversely and / or longitudinally to the longitudinal direction of the carrier plate. This alignment in combination with the elongate shape causes in particular a better Verkral- lation of the tile adhesive with the support plate. In a particularly preferred embodiment of the invention, a special arrangement of the projections and / or recesses is provided, in which these extend in rows transversely and / or longitudinally to the longitudinal direction of the carrier plate and are arranged alternately from their orientation. Especially with such Training and arrangement results in a good clawing of the tile adhesive with the support plate.

Preferably, at least one knob having a three-axis stud bottom has three long sides, wherein the central area of the three-axis stud bottom is defined by a circle tangent to all long sides. This geometric design of the knob or the knobbed bottom allows particularly high decoupling properties with a simultaneously excellent drainage function.

In an advantageous embodiment of the inventive concept, the nub or the three-axis nubbed bottom is concave at least on one long side. This concave configuration of the long side leads to improved demoulding, since in particular there are no corners between the long sides. An improved demolding requires a simpler and / or improved manufacturing process.

In addition, in a preferred embodiment of the decoupling web according to the invention in the region of the long side and / or leg side of the nub or the nubbed bottom at least one formation for forming a noppeninnenseitigen undercut is provided. It is ultimately understood that the long side is formed for example by two and / or one leg side. The tile adhesive penetrates into the undercut during the Ausachteinsin, so that an improved clawing is caused. This in turn leads to a fixation and / or the positive fixing of the applied on the decoupling tile tile track or covering elements.

In a particularly advantageous embodiment of the inventive concept, the formation to form the noppeninnenseitigen undercut is sickle-shaped or arcuate and / or arcuate and / or crescent-shaped. This arc-shaped formation leads, in particular, to the fact that improved demoulding is made possible in the production of the decoupling web. In contrast to angular undercuts advantageously a lighter separation between the mold and the decoupling web is ensured in a rounded or sickle-like shape of the undercut. Thus, the decoupling web can not be damaged in particular during demolding. Incidentally, the rounded undercuts preferably serve to nungsspitzen the shear stress of the lining elements reduced and / or distributed evenly on the decoupling web.

In a further embodiment of the invention, the formation is formed by a protruding from the nub interior projection. In a particularly advantageous embodiment of the projection is provided in the region of the stud bottom, wherein the projection passes in particular directly into the stud bottom. This direct transition of the projection into the dimpled bottom results in improved demolding, so that in particular even in the not yet completely hardened state of the decoupling web material, the mold can be easily removed from the decoupling web without fear of damaging the decoupling web during demoulding is. This advantage also results in particular when the molding extends over at least 40%, preferably between 50% and 100% and in particular between 60% and 90% of the length of the long side and / or leg side. These dimensions require that the end of the nub or the three-axis stud bottom, which results from two tapered long sides, is undercut-free or has no formation in this area. In this embodiment, the molding tool in the end region in each case have sharp corners without causing damage to the decoupling web during demoulding. In a further embodiment of the inventive concept, it is provided that in each case the end region of the nub or of the three-axis stud bottom, which results from two tapered long sides, is rounded and formed without corners. In this case, in a preferred embodiment of the embodiment of the decoupling web, the radius of a concave long side is several times greater than the radius of an end region, preferably the radius of a concave long side is greater than the radius of the end region by a factor of two. Due to the concave longitudinal sides and the rounded and / or convex end portions of the long sides results in a curved knob shape, the voltage spikes occurring significantly reduced or partially completely avoided. At the same time, these end areas, which are in particular undercut-free, counteract air pockets and thus simplify filling. Incidentally, it has been found in experiments carried out that it is particularly advantageous if the nub and / or the three-axis nubbed base is mirror-symmetrical with respect to a center axis running essentially parallel to the longitudinal direction. This mirror-symmetrical knob axis is not only production-specific, but also very advantageous with regard to the product properties of the decoupling track, as will be discussed below.

In a further advantageous embodiment of the inventive concept it is provided that the angle of the leg extending from the central region between the mutually adjacent, spaced leg axes is at least 90 °.

In order to ensure an optimized arrangement of the nubs on the decoupling web, the invention provides in a further embodiment that the leg length of a leg, in particular of the longitudinal direction of the decoupling parallel leg, is less than the other two leg lengths. It is particularly advantageous if the angle which is arranged between the leg axis of the shorter leg and the leg axis of the adjacent leg is greater than 120 ° and in particular is smaller than 130 °. Due to a preferred mirror-symmetrical arrangement, two larger angles are provided in the knob or in the three-axis knobbed bottom and the angle which is included between the leg axes of the longer legs, is accordingly smaller than 120 °. In comparison to the rectangular and / or rotationally symmetrical geometries customary in the prior art, this geometry has the particular advantage that improved decoupling properties of the entire decoupling trajectory when using the nub with the aforementioned properties are produced.

It should be pointed out in this connection that particularly improved decoupling property results when a multiplicity of knobs having the three-axis studded bottom according to the invention are provided on the decoupling track. It is provided in a preferred embodiment that the transverse to the longitudinal direction of the support plate knobs are arranged such that there is no continuous transverse to the longitudinal direction of the support plate straight line on the support plate and / or arranged in the longitudinal direction of the support plate extending nubs such are that there is no continuous line, straight line extending in the longitudinal direction of the carrier plate and / or that longitudinally and transversely to the longitudinal direction of the carrier plate extending nubs are arranged such that there is no continuous, running obliquely to the longitudinal direction of the support plate straight line on the support plate. In this case, "continuous" means a connection from one edge of the decoupling track to the opposite edge of the decoupling track on the other longitudinal or transverse side of the decoupling track. According to the invention, this is achieved, in particular, by using a knob having a three-axis studded bottom with the aforementioned properties, which enables this embodiment only through the arrangement and thus through the interaction of the studs.

By the aforementioned embodiment, weakening lines and / or predetermined breaking edges of the dimpled sheet are avoided, which exceed the entire nip diameter, in particular by a multiple. The arrangement of the knobs in the aforementioned manner results in channel sections between the knobs which have a course, in particular meandering, in right and left curves, so that the channel sections, preferably undulating, extend over the carrier plate. By avoiding a straight course of the individual channels, it can advantageously be precluded that straight lines of weakening are formed over the decoupling web. Ultimately, it is irrelevant how the Entkopplungsbahn is laid in a room, so that in any direction a running in this direction channel section would hit a nub in a rectilinear continuation, so that the attenuation section line formed by the respective channel section is interrupted and Thus, in particular the formation of longer lines of weakness are prevented. Accordingly, it can be ensured regardless of the orientation of the decoupling web during laying that formed joints in the laid flooring repeatedly sections over nubs away, so that joints do not extend congruently over a longer channel section of the decoupling.

When using the triaxial knob, the carrier plate according to the invention preferably has exclusively such channels which extend from one side edge to another side edge of the carrier plate and extend in right and left curves relative to the transverse direction of the decoupling path or the carrier plate. Each space between two adjacent knobs represents a channel section and is part of a channel, so that straight across the support plate extending lines of weakness or predetermined breaking edges between spaced nubs are excluded. In the end, it is understood that in a further embodiment, in particular when using a square and / or elliptical and / or rectangular nub, such weakening lines and / or predetermined breaking edges of the decoupling trajectory can result.

In another preferred embodiment, the nubs are arranged in both the longitudinal and transversely extending rows, the centers of the longitudinally extending nubs being provided on a line at least substantially parallel to the longitudinal direction of the decoupling trajectory, and the centers being transverse to Longitudinally extending nubs are arranged on an at least substantially perpendicular to the longitudinal direction line. This arrangement of the nubs leads to manufacturing advantages, since these, preferably symmetrical, arrangement of the nubs by an embossing device, preferably a nub roller, by means of molding tools in a sheet-like material that the embossing device is supplied as the base material of the decoupling mat, can be introduced. The molds are arranged on the nub roller, so that the embossing of the knobs can be done in a continuous manufacturing process.

Another possible and supplementary aspect of the present invention is that the nubs located in a row running substantially parallel to the longitudinal direction are arranged one behind the other in such a way that the shorter leg of the nubs or nubbed bottom is aligned in the longitudinal direction. In an immediately adjacent row of knobs, which extend at least substantially parallel to the longitudinal direction of the decoupling web, the shorter limbs of the knobs are oriented opposite to the longitudinal direction. In this case, it is possible, in particular, to avoid the aforementioned weakening lines over the decoupling web, in that the resulting channel sections between the adjacent knobs are not rectilinear. In this case, the shorter legs according to the invention ensure that the knobs are arranged in longitudinal and transverse rows to the carrier plate, without, however, having or forming a weakening line. In a further embodiment of the inventive concept, it is preferably provided that the arrangement of the dimples on the carrier plate is designed so that the shortest distance between two adjacent dimples always has approximately the same size, in particular with a deviation of +/- 20%, preferably +/- 10%. This produces, in particular, an identical or approximately equal channel width, the channels extending in a meandering manner over the carrier plate due to the shape of the pimples. Advantageously, in order to form the same channel widths and / or to ensure an at least substantially shortest constant section between two adjacent knobs, a leg of the knobs should be made shorter.

In a further preferred embodiment of the inventive concept it is provided that the nubs are arranged and / or formed so as to give rise to approximately the same flow cross-section in the channels, in particular with a deviation of +/- 20%, preferably +/- 10 %.

In principle, it is understood that for the connection between the decoupling web and the substrate on the outside of the dimpled bottoms, a flat connecting means can be provided. Preferably, this connecting means is attached to the dimpled floors, wherein preferably the connecting means as fleece and / or fabric and / or scrim and / or grid and / or paper, in particular in full-surface and / or lattice-like design is formed. According to the invention, the connecting means specifies that the dimpled base is firmly connected to the substrate via the connecting means, so that in particular its adhesive tensile strength is increased. Preferably, the connecting means is introduced directly into the outside of the studded floors during the manufacturing process of the decoupling web. Due to the fixed connection of the decoupling web to the substrate by means of the connecting means, a displacement between the covering layer and the decoupling web is preferably avoided.

The arrangement of the connecting means on the studded floors is preferably designed such that the channels or channel sections result between the outer sides of the studs and the connecting means, via which a dehumidification and / or a venting is possible. The connecting means is usually facing the ground on which the decoupling web is placed. The openings in the individual nubs are aligned to the laying side, so that the tile adhesive can be introduced into the nubs or in the nub interior.

In a further preferred embodiment of the present invention, the height of the nubs between 1 and 5 mm, preferably 2 to 4 mm, more preferably 2.5 to 3.5 mm. This comparatively low dimple height enables a wrestle overall layer construction and implies the reduced amount of tile adhesive required for the connection between the decoupling panel and the tiles. Nevertheless, due to the particular knobbly shape and formation, a firm bond between the tile adhesive and the decoupling web is achieved while at the same time achieving an excellent decoupling effect.

In another preferred embodiment, the clear distance of adjacent knobs has a width greater than 2 mm, in particular between 3 mm to 9 mm, preferably 4 mm to 8 mm, more preferably 5 mm to 6 mm. This clear distance also determines the width of the channel section and thus defines the clearance between adjacent nubs. Due to the available width, the sewer section not only ensures good dehumidification and ventilation of the subfloor, but also uniform heat distribution, especially in system structures with underfloor heating.

Moreover, it is provided in a further preferred embodiment that the ratio of the area of the dimpled bottoms of all dimples to the carrier plate is preferably between 40% to 70%, more preferably between 45% to 55% and in particular at least substantially 50%. In experiments carried out has been found that particularly good decoupling values are achieved with a particularly strong fixation of the tile adhesive to the decoupling web while maintaining the aforementioned ratio. The aforesaid ratio also defines, together with the dimple height, inter alia, the amount of tile adhesive required, which is used to bond the decoupling web and the surfacing element. On the support plate in particular a load distribution of the shear stress occurring is made possible by the channels, wherein preferably a compensation of the occurring voltages is performed. In experiments, it was finally found that the ratio of 40% to 60%, preferably 45% to 55%, is particularly advantageous and has good decoupling properties and good bond strength.

In addition, a method for producing the decoupling web is provided with a carrier plate and a plurality of projecting from the carrier plate plane nubs. In the method according to the invention, provision is made for a plurality of projections and / or recesses to be introduced in the side of the dimpled bottom facing the dimple interior, and / or for the carrier element to be turned into the side facing the dimpled interior. plate a plurality of projections and / or recesses is introduced, in particular wherein the surface is roughened.

Preferably, a structured and / or roughened surface is thus produced. The textured surface may have irregular and disordered protrusions and depressions.

In this case, the studded bottoms of immediately adjacent studs, in particular three-axis, are preferably formed transversely to the longitudinal direction and in the longitudinal direction of the carrier plate. Ultimately, however, it is understood that according to the invention other nub structures can be provided.

In a preferred embodiment of the method according to the invention, it is provided that the projection is produced by laser processes, plasma processes, mechanical processes, preferably radiation, in particular by means of sand and / or nut shells, and / or by embossing at and / or after the production of the decoupling web. It has been found that the above-mentioned method results in a surface roughened or roughened ideally for the subsequent processing of the decoupling web.

In the end, it goes without saying that the protrusions and / or depressions can be introduced into the decoupling web or into the carrier plate and / or into the burl bottom following the production of the decoupling web, in particular in a separate process step.

In terms of manufacturing technology, it makes sense to carry out the impressing of the projections and / or depressions into the decoupling web directly during the production of the decoupling web, so that the projections and / or depressions are formed directly by depressions and / or elevations on the forming tools and / or the impressing device or the nub roller are arranged.

In another embodiment, it is provided that the impressing after the production of the decoupling web is performed by an additional or further embossing roll, which is in particular heated. This additional embossing roller joins the actual nub roller, via which the decoupling web is generated as such, in the direction of production. The surface modification or structuring may alternatively be by mechanical methods such as blasting, for example using sand and / or nut shells. A roughening or roughening of the surface is given in mechanical processes by the use of, for example brushes and / or sandpaper.

A disadvantage of a mechanical roughening by means of sanding, brushing and / or on a material removal by means of an abrasive paper is the comparatively high material removal, which leads to a weakening of the knobs and the decoupling web as a whole. It has surprisingly been found that the material removal process can be reduced by up to 30% in comparison to sanding or brushing by the production method of laser radiation, plasma radiation, embossing and / or radiation. In particular, the structured surface can be intentionally predetermined and converted by the production method according to the invention, which is not possible during brushing and sanding.

The aforementioned methods lead to a structured surface or to a profiling of the surface, so that in particular an increased roughness is caused. The roughening or structuring of the surface by means of Nussstrahlen proved to be particularly advantageous in the experiments carried out.

In the plasma process, high-energy electrons and ions are generated in particular directly from the surrounding atmosphere by means of strong electric fields and used to generate a plasma. As a result, the surface structure of the decoupling path is attacked accordingly. The laser method preferably has the treatment of the surface of the decoupling path with a pulsed laser beam source, which can preferably be directed onto the surface of the decoupling path with a high radiation intensity. When laying the decoupling mat on a substrate surface, an adhesion-promoting layer between the decoupling web and the covering elements can preferably be applied to the decoupling web by brushing and / or spraying and / or brushing on. In principle, it is also conceivable to apply an adhesion-promoting layer to the decoupling web by brushing and / or spraying and / or brushing on during the production of the decoupling web. As a result, the invention relates to a decoupling web having a carrier plate and a plurality of protuberances protruding from the carrier plate, wherein adjacent nubs are arranged transversely to the longitudinal direction of the carrier plate and in the longitudinal direction of the carrier plate, to improve the decoupling properties and to increase the adhesive tensile strength a plurality of projections and / or depressions on the dimpled bottoms and / or the surface of the carrier plate which faces away from the dimpled bottoms. Finally, the invention also relates to a method for producing a decoupling web, in particular with the projections and / or depressions according to the invention.

Incidentally, it is understood that in the aforementioned intervals and range limits contain any intermediate intervals and individual values and are to be regarded as disclosed essential to the invention, even if these intermediate intervals and individual values are not specified concretely.

Entkopplungsbahn according to FIG. 17. 1 shows a part of a decoupling web 1 with a carrier plate 2 and a plurality of nubs 4 projecting from the carrier plate plane 3. Adjacent nubs 4 are arranged transversely to the longitudinal direction 5 (in the transverse direction 15) of the carrier plate 2 and in the longitudinal direction 5 of the carrier plate 2. In addition, Fig. 1 illustrates that transversely to the longitudinal direction 5 (in the transverse direction 15) and in the longitudinal direction 5 of the support plate 2 directly adjacent knobs 4 have a three-axis studded bottom 10. In Fig. 14 it is shown that other shapes and / or structures for the nub 4 may be provided in further embodiments. FIG. 14 illustrates that an elliptical, in particular cylindrical, and a diamond-shaped nub 4 are provided on a decoupling web 1. It goes without saying that, in further embodiments, exclusively cylindrical and / or diamond-shaped and / or rectangular knobs 4 are present on the decoupling web 1. In Fig. 14 is not shown, however, that the decoupling web 1 has projections 21 a, 21 c and / or recesses 21 b, 21 d. These projections 21 a, 21 c and / or recesses 21 b, 21 d may have different shapes and structures in a further variant, not illustrated, in particular where they form a structured surface of the stud bottom 10 and / or the support plate 2. Furthermore, it is not shown that the projections 21 a, 21 c and / or depressions 21 b, 21 d on decoupling webs 1 may be present together with different shapes of the nub 4. Further, it is not shown that the nub 4 may be formed multi-legged, where it may have two or more legs. In the embodiments according to FIGS. 1 to 13, the three-legged shape of the nub 4 or of the nubbed bottom 10 is provided.

The three-axis design of the nub 4 or the stud bottom 10 requires that three legs 12, 13 are provided. The three-axis design of the stud bottom 10 is visible in plan view of the decoupling web 1 and, consequently, in plan view of the knob 4. The immediate vicinity of the nubs 4 in the longitudinal direction 5 and in the transverse direction 15 occurs in a group of at least three nubs 4. This means that at least three immediately adjacent studs 4 in the longitudinal direction 5 and in the transverse direction 15 have a three-axis formed stud bottom 10. In the arrangement of the nubs 4 on the support plate 2 is provided that the knobs 4 and the studded floors 10 neither overlap nor overlap. It goes without saying that in one not illustrated embodiment of the decoupling web 1 according to the invention can be provided that various Noppenformen or shapes of the stud bottom 10 - both three-axis and any shapes - can be used on the decoupling web 1. In this embodiment, not shown, a group of at least three immediately adjacent knobs 4 is preferably formed with a three-axis studded bottom 10.

Alternatively and / or in addition to the three-axis design of immediately adjacent knobs 4 in the longitudinal direction 5 and in the transverse direction 15 is provided that on the decoupling web 1 at least one nub 4 with a three-axis studded bottom 10 with three long sides 6a is present. According to FIGS. 3 and 4, it is made clear that the central region 7 of the nub 4 or of the nubbed bottom 10 is defined by a circle which tangentially contacts all long sides 6. In Fig. 3 and 4, various embodiments of the three-axis knob shape are shown with different three-axis Noppenböden 10 with three long sides 6a.

Furthermore, FIG. 1 shows the arrangement of the nubs 4 according to FIG. 4 on a decoupling web 1, wherein all the nubs 4 have a three-axis nubbed bottom 10.

In one embodiment variant, not shown, only a studded shape with a three-axis studded bottom 10 is provided with three long sides 6a as shown in FIG. 3 or 4, which is introduced into a support plate 2, wherein the remaining studs 4 have known studded structures, for example cylindrical and / or cup-shaped ,

Incidentally, Figs. 3 and 4 illustrate that the long side 6 of the knob 4 and the stud bottom 10 is concave. In one embodiment, not shown, only one long side 6a of the nub 4 or two long sides 6a of the nub 4 is concave.

A nub interior 20 is formed by the stud bottom 10 and at least one side wall adjoining the stud bottom 10, the three-dimensional shape of the stud 4 resulting from the at least one side wall. FIG. 2 illustrates that in the exemplary embodiment shown there is a notch-side undercut 8. This nippeninnenseitige undercut 8 is formed by the molding 8, wherein the formation 8 in the illustrated embodiment sickle-shaped and / or arc-shaped and / or crescent-shaped. The formation 8 is also formed by a protruding from the nub interior 20 projection 9. The molding 8 is provided as shown in FIG. 3 and 4 in the region of the long side 6 a of the nub 4. 2, it is clear that in the illustrated exemplary embodiment, the projection 9 is arranged in the region of the stud bottom 10, wherein the projection merges into the stud bottom 10. Incidentally, FIGS. 3 and 4 illustrate that the formation 8 extends approximately over 90% of the long side 6a. In one embodiment, not shown, it is provided that the molding 8 extends over at least 40%, preferably in other embodiments between 50 and 100% and in particular between 60 and 90%, of the long side 6a.

Furthermore, FIGS. 3 and 4 show that the end region 1 1 resulting from two tapered long sides 6 a is undercut-free and thus neither has an undercut 8 nor a projection 9 for the formation of the undercut 8. In addition, in the exemplary embodiment shown resulting end portion 11 rounded and formed without corners, the rounding will be described with reference to a circular arc section. The radius which characterizes the concavity of the long side 6a is in this case greater by a multiple or multiple than the radius which determines the circular arc section of the end region 11.

In addition, FIGS. 3 and 4 illustrate that the nub 4 or the three-axis nubbed bottom 10 is mirror-symmetrical with respect to a central axis running at least substantially parallel to the longitudinal direction 5. This mirror symmetry is also clear from FIG. 1. 3 and 4, three spaced-apart legs 12, 13, which extend from the central region 7, are provided in the three-axis knobbly shape of the stud bottom 10.

With reference to FIGS. 3 and 4 it can be seen that a leg length 14 of a leg 13, which runs parallel to the central axis, is shorter than the respective other two leg lengths 14 of the leg 12. In addition, various angles of the leg axes are provided in the illustrated embodiment. In principle, in all illustrated nub shapes, the nub 4 angles between two spaced leg axes greater than 90 ° intended. In the embodiment according to the invention of the nub 4 according to FIGS. 3 and 4, it is provided that the angle of the leg axis of the shorter leg 13 to the leg axis of the adjacent leg 12 is greater than 120 °, in the illustrated exemplary embodiment approximately 123 °. Accordingly, the angle between the leg axes of the legs 12 is less than 120 °, about 1 14 °.

The configuration of the nub 4 with a three-axis nubbed bottom 10 allows the nub arrangement according to FIG. 1. In this embodiment, it is provided that the nubs 4 are arranged transversely to the longitudinal direction 5 of the support plate 2 such that on the support plate 2 and the support plate level 3 no continuous, transversely to the longitudinal direction 5 and thus in the transverse direction 15 of the support plate 2 extending straight line. In addition, it is likewise provided that the knobs 4 extending in the longitudinal direction 5 of the carrier plate 2 are arranged in such a way that there is no continuous line running on the carrier plate 2 in the longitudinal direction 5 of the carrier plate 2. However, not only straight lines in the longitudinal direction 5 and 15 have been avoided in the transverse direction, but also longitudinally and transversely to the longitudinal direction 5 of the support plate 2, the knobs 4 are arranged such that on the support plate 2 is not continuous, obliquely to the longitudinal direction 5 of the support plate. 2 running straight line results. Consequently, there is no straight line on the decoupling track 1, since in each case individual line sections are interrupted by the knobs 4. The channel portion occurring between two nubs 4 with the clear distance 19 is arranged such that it extends meander-shaped according to FIG. 1 via the decoupling web 1. The possible resulting in the channel section resulting lines can not continue beyond the support plate 2 away straight. It projects in each case a leg 12, 13 of an adjacent nub 4 in the channel section between two nubs 4 inside.

In addition, it goes without saying that this can also be realized when using a different stud shape. Other three-axis knobbed shapes of the dimpled base 10 of the knob 4 are shown with reference to FIG. 5 and designated by the embodiments 1 to 13. The arrangement of these possible Noppenformen on the support plate 2 may be configured such that the above-mentioned continuous straight lines on the support plate 2 does not arise. The three-axis embodiments 1 to 13 according to FIG. 5 each show at least three leg sides 6b, it being understood that the long side 6a is formed by at least one leg side. It is not shown that the embodiment variants 1 to 13 have an undercut 8 in the region of the long side can and / or that the formation 8 can extend over at least 40% of the long side 6a or over the leg side 6b.

Fig. 6 shows that when using a triangular-shaped knob shape of the stud bottom 10 of the knob 4, an arrangement on the support plate 2 is provided such that there is no continuous straight line of the channel portion of adjacent studs 4 on the support plate 2. The centers of the pimples

4 or the studded floors 10 according to FIG. 3 are parallel to the longitudinal direction

5 extending straight lines and arranged parallel to the transverse direction 15 lines.

Also in the three-axis configuration of the stud bottom 10 according to FIGS. 3 and 4, these studs 4 are arranged on the carrier plate 2 in such a way that according to FIG. 1 an arrangement results, wherein the studs 4 in the longitudinal direction 5 and in the transverse direction 15 and in Rows are arranged running. The centers of the nubs 4 extending in the longitudinal direction 5 are arranged at least on a line running essentially parallel to the longitudinal direction 5. In addition, the centers of the nubs 4 extending transversely to the longitudinal direction 5 are arranged on a line running at least substantially perpendicular to the longitudinal direction 5 and thus in the transverse direction 15. This arrangement of the nubs 4 results in a symmetrical Noppenfolge within the respective row, being made possible in particular by this arrangement, that the above-mentioned continuous straight lines or lines of weakness do not arise on the support plate 2. However, not only the centers of the knobs 4 and the studded floors 10 are arranged on the decoupling web 1 according to FIG. 1 in rows, but the arrangement is carried out such that in a row extending at least substantially parallel to the longitudinal direction 5 consecutively arranged knobs. 4 extend so that the shorter leg 13 of the knobs 4 in the longitudinal direction 5 is aligned. In an immediately adjacent row extending at least substantially parallel to the longitudinal direction 5, the knobs 4 arranged one behind the other are aligned such that the shorter leg 13 of the knobs 4 is oriented opposite to the longitudinal direction 5. This results in an alternating nub orientation in a row running at least substantially parallel to the transverse direction 15.

For arranging the decoupling web 1 on a substrate 18, a connecting means 17 according to FIG. 2 is provided. This connection means 17 is on the Outside 16 of the studded floors 10 are arranged. In the illustrated embodiment, the connecting means 17 is attached to the outside 16 of the studded floors 10. As a connecting means 17, a fleece was used in the illustrated embodiment.

In addition, the nub 4 according to FIG. 2 has a height of 3 mm. In other embodiments, which are not shown graphically, a height between 1 to 4 mm, more preferably between 2.5 to 3.5 mm, is provided. Furthermore, the clear distance 19 of adjacent knobs 4 in the illustrated embodiment is greater than 2 mm. The clear distance 19 of the nubs 4 varies on the decoupling web 1 according to FIG. 1, so that approximately a clear distance 19 between 3 mm to 9 mm can be provided, preferably between 4 to 8 mm, more preferably between 5 to 6 mm. Incidentally, FIG. 1 illustrates that the ratio of the area of the studded bottoms 10 of all knobs 4 to the surface of the carrier plate 2 is at least essentially about 50%. In other embodiments, the ratio may be between 40% to 70%, preferably between 45% to 55%.

Incidentally, Fig. 2 illustrates that tiles 23 are provided above the support plate 2. Between adjacent tiles 23 there are joints 24. To connect the tiles 23 with the decoupling web 1, a tile adhesive is provided, which is applied both in the nub interior 20 and on the support plate 2. He gets caught within the undercut 8 and penetrates into the projection 9 a. Regardless of the orientation of the decoupling web 1 on a substrate 18, it follows that the joints 24 between the tiles 23 do not coincide with a weakening line or a continuous line on the carrier plate 2. The possible continuous line resulting between two nubs 4 can not be continued beyond adjacent nubs 4. In further embodiments, it is provided according to FIGS. 7 to 13 that projections 21a, 21c and / or depressions 21b, 21d can be present both on the stud bottom 10 and on the carrier plate 2.
