Description
Carrier tile consisting of film-like plastic The invention relates to a carrier tile consisting of film-like plastic for a floor, wall or ceiling structure, in particular for a tile-clad wall or floor structure, for achieving decoupling between the base and the surface cladding to be applied to the film-like tile.
Tile coverings are often laid by what is known as the thin-bed method, a suitable contact adhesive being used in order to fix the tile coverings to the base. On account of different thermal expansions of the cladding and of the base and the associated stresses, cracks may occur in the surface cladding and may cause parts of the surface cladding to come loose.
To reduce such stress differences, according to DE 37 04 414 Al, a carrier plate consisting of film-like plastic was proposed, which comprises dovetailed grooves which are open alternately on both sides and which can be moved transversely with respect to the run of the grooves under compressive and tensile stress. A
net-like nonwoven is provided on one side of the carrier tile, in order to connect the carrier tile to the base, such as, for example, screed, and to achieve higher adhesion with an adhesive. This carrier tile has the disadvantage that it is expandable or compressible only in a limited direction, to be precise transversely with respect to the longitudinal extent of the dovetailed grooves. The necessary stress reduction is often not possible by means of such a carrier tile.
In order to allow stress reduction in both directions, according to DE 299 24 180 Ul, a carrier tile was proposed, which comprises on one tile side intersecting embossings which in each case form circumferentially closed chambers. The chambers serve for receiving an adhesive or mortar, thus giving rise to an intimate bond with the adhesive or mortar layer and with the surface cladding applied to it. By virtue of these intersecting embossings, a film-like tile is proposed which is expandable or contractable at least to a slight extent in both directions of its plane of extent, so that stress differences arising from the base and the cladding can be absorbed by the carrier tile. In addition, the chambers have undercuts, with the result that the adhesive or mortar stilts introduced into the chambers hook together with the undercuts of the chambers.
This embodiment has the disadvantage that, in the region of the undercut, the mortar stilts have a necking with respect to the contact surface in the bottom of the chambers, and that, in the region of the undercut, there is a cracking of the contact elements introduced in the chambers, these contact elements coming loose from the mortar layer lying above them.
The positive cramping achieved initially by means of the undercut is loosened due to the formation of cracks in the necking plane. The intimate bond is no longer afforded, and the stress reduction between the base and the cladding is no longer possible.
The object on which the invention is based is, therefore, to propose a carrier tile consisting of film-like plastic for floor, wall or ceiling construction, in particular for tile-clad wall or floor construction, by means of which an improvement in the decoupling or reduction of different stresses between the base and surface cladding becomes possible.
This object is achieved, according to the invention, by a carrier tile consisting of a plastic film for a floor, wall or ceiling structure, for achieving decoupling between the base and a surface cladding to be applied to the carrier tile which has a multiplicity of chambers which are formed by depressions out of a plane of the carrier tile and outer end faces of which form a first tile side, the depressions being designed for receiving a curing contact means, such as mortar or adhesive, provided for forming a contact layer with the surface cladding to be applied, and with a net fabric or nonwoven arranged on the first tile side, characterized in that the chambers between the first and an opposite tile side have an undercut-free wall portion, and in that a further net fabric overlapping the depressions is provided on the opposite tile side.
As a result of the undercut-free design of the wall portions, there is in the respective chamber no cross-sectional narrowing of mortar or adhesive stilts which enters the chamber in spite of the net or net-like fabric. There is therefore an improved force flux for dissipating the forces under vertical loads acting from above, and cracking in the transitional region between the mortar stilts and the sheet mortar layer is prevented. The net fabric ensures that the adhesive or mortar layer, which is suitable, for example, for flags, fine-stoneware slabs, ceramic or clay tiles or tiles consisting of further materials, such as plastics, wood, cork or the like, bonds with the tile side to which the net fabric is applied. What is additionally achieved is that the net fabric is stretched out or tied in between the mortar or adhesive layer receiving the surface cladding and the contact elements or mortar stilts and forms a cramping.
Alternatively, a surface cladding, such as, for example, plaster, can also be applied directly, which is anchored firmly with the net fabric and is decoupled from the base. By virtue of this embodiment according to the invention of the carrier tile, an optimum reduction of stresses which occur and permanent decoupling between the base and a surface cladding are achieved.
-3a-According to a first advantageous embodiment of the invention, there is provision for the chamber-wall portions to extend vertically between the end faces forming one tile side and the opposite tile side which is formed by surface portions connecting the chambers.
Column-shaped contact elements can thereby be formed.
The area in horizontal projection or the form of the chamber may in this case be configured with any desired geometry. For example, triangular or polygonal or even round areas in horizontal projection of the chambers may be formed.
Tile coverings are often laid by what is known as the thin-bed method, a suitable contact adhesive being used in order to fix the tile coverings to the base. On account of different thermal expansions of the cladding and of the base and the associated stresses, cracks may occur in the surface cladding and may cause parts of the surface cladding to come loose.
To reduce such stress differences, according to DE 37 04 414 Al, a carrier plate consisting of film-like plastic was proposed, which comprises dovetailed grooves which are open alternately on both sides and which can be moved transversely with respect to the run of the grooves under compressive and tensile stress. A
net-like nonwoven is provided on one side of the carrier tile, in order to connect the carrier tile to the base, such as, for example, screed, and to achieve higher adhesion with an adhesive. This carrier tile has the disadvantage that it is expandable or compressible only in a limited direction, to be precise transversely with respect to the longitudinal extent of the dovetailed grooves. The necessary stress reduction is often not possible by means of such a carrier tile.
In order to allow stress reduction in both directions, according to DE 299 24 180 Ul, a carrier tile was proposed, which comprises on one tile side intersecting embossings which in each case form circumferentially closed chambers. The chambers serve for receiving an adhesive or mortar, thus giving rise to an intimate bond with the adhesive or mortar layer and with the surface cladding applied to it. By virtue of these intersecting embossings, a film-like tile is proposed which is expandable or contractable at least to a slight extent in both directions of its plane of extent, so that stress differences arising from the base and the cladding can be absorbed by the carrier tile. In addition, the chambers have undercuts, with the result that the adhesive or mortar stilts introduced into the chambers hook together with the undercuts of the chambers.
This embodiment has the disadvantage that, in the region of the undercut, the mortar stilts have a necking with respect to the contact surface in the bottom of the chambers, and that, in the region of the undercut, there is a cracking of the contact elements introduced in the chambers, these contact elements coming loose from the mortar layer lying above them.
The positive cramping achieved initially by means of the undercut is loosened due to the formation of cracks in the necking plane. The intimate bond is no longer afforded, and the stress reduction between the base and the cladding is no longer possible.
The object on which the invention is based is, therefore, to propose a carrier tile consisting of film-like plastic for floor, wall or ceiling construction, in particular for tile-clad wall or floor construction, by means of which an improvement in the decoupling or reduction of different stresses between the base and surface cladding becomes possible.
This object is achieved, according to the invention, by a carrier tile consisting of a plastic film for a floor, wall or ceiling structure, for achieving decoupling between the base and a surface cladding to be applied to the carrier tile which has a multiplicity of chambers which are formed by depressions out of a plane of the carrier tile and outer end faces of which form a first tile side, the depressions being designed for receiving a curing contact means, such as mortar or adhesive, provided for forming a contact layer with the surface cladding to be applied, and with a net fabric or nonwoven arranged on the first tile side, characterized in that the chambers between the first and an opposite tile side have an undercut-free wall portion, and in that a further net fabric overlapping the depressions is provided on the opposite tile side.
As a result of the undercut-free design of the wall portions, there is in the respective chamber no cross-sectional narrowing of mortar or adhesive stilts which enters the chamber in spite of the net or net-like fabric. There is therefore an improved force flux for dissipating the forces under vertical loads acting from above, and cracking in the transitional region between the mortar stilts and the sheet mortar layer is prevented. The net fabric ensures that the adhesive or mortar layer, which is suitable, for example, for flags, fine-stoneware slabs, ceramic or clay tiles or tiles consisting of further materials, such as plastics, wood, cork or the like, bonds with the tile side to which the net fabric is applied. What is additionally achieved is that the net fabric is stretched out or tied in between the mortar or adhesive layer receiving the surface cladding and the contact elements or mortar stilts and forms a cramping.
Alternatively, a surface cladding, such as, for example, plaster, can also be applied directly, which is anchored firmly with the net fabric and is decoupled from the base. By virtue of this embodiment according to the invention of the carrier tile, an optimum reduction of stresses which occur and permanent decoupling between the base and a surface cladding are achieved.
-3a-According to a first advantageous embodiment of the invention, there is provision for the chamber-wall portions to extend vertically between the end faces forming one tile side and the opposite tile side which is formed by surface portions connecting the chambers.
Column-shaped contact elements can thereby be formed.
The area in horizontal projection or the form of the chamber may in this case be configured with any desired geometry. For example, triangular or polygonal or even round areas in horizontal projection of the chambers may be formed.
According to an alternative embodiment of the invention, there is provision for the wall portions to have a conical run between one tile side and the opposite tile side, these wall portions narrowing from one tile side, which is formed by the surface portions connecting the chambers, to the other tile side, which is formed by the end faces of the chambers. These conical surfaces make it easier for the mortar or adhesive to be introduced completely into the chambers for complete filling-up with mortar or adhesive.
The inclination of the conically running wall portions is advantageously provided at an angle of less than . This optimizes force absorption, on the one hand, 15 and the filling of the chambers, on the other hand.
The net-like fabric covering the depression of the chambers is advantageously glued to the surface portions of the one tile side which connect the 20 chambers. As a result, different materials may be selected for the net-like fabric and for the carrier tile consisting of film-like plastic. Furthermore, gluing affords the advantage that the net-like fabric projects slightly with respect to the surface portions, and additional meshing with the adhesive or mortar layer adhering to the surface cladding becomes possible.
According to an alternative embodiment of the invention, there is provision for the net-like fabric covering the depressions to be welded to the surface portions connecting the chambers. It thereby becomes possible for the net-like fabric and the carrier tile to be connected, in the contact regions, so as to form a unit, with the result that very high strengths can be achieved. At the same time, the advantages of the glued-on embodiment of the net-like fabric can be preserved. Alternatively, there may also be provision for the net-like fabric to be embedded at least partially into the tile side during the welding-on process.
To produce a fusion-welded joint between the net-like fabric and the carrier tile, there is advantageously provision for the net fabric to be produced from a thermoplastic. Such thermoplastics are acid-resistant and have high strength.
According to a further advantageous embodiment of the invention, there is provision for the net-like fabric overlapping or covering the depressions to have a mesh width of at least 0.04 mmZ, in particular 0.5 to 5 mm`.
It thereby becomes possible easily to introduce or fill the chambers with an adhesive or mortar layer and with further flowable and curable materials. At the same time, however, it is ensured that a sufficient number of meshes overlap the depression or the chambers, in order to make it possible to fix the adhesive or mortar stilts within each chamber. Preferably, there is provision for at least two meshes to be provided for each chamber. The size of the chamber and the mesh width of the net-like fabric or nonwoven can in this case be adapted to one another so as to afford optimum cramping.
The net-like fabric for covering the depressions is preferably produced in the manner of a grid from rovings welded to one another. In this case, there is provision for the net-like fabric to have identical tensile strengths in both directions of the plane of extent, in order to allow a uniform stress reduction.
The rovings for the net fabric are preferably formed from twisted individual fibres, in order to have a high compressive strength.
According to a further embodiment of the invention, there is provision for the mesh width of the net-like fabric or nonwoven to be designed to be smaller than a surface portion between two chambers. As a result, at least two intersecting fibres of the fabric or at least one warp and one weft of the fabric can be welded or glued to the surface portion. The free orifice of the chamber can thereby be spanned by a tauter fabric or nonwoven portion.
The invention and further advantageous embodiments and developments of this are described and explained in more detail below by means of the examples illustrated in the drawings. The features to be gathered from the description and the drawings may be used, according to the invention, individually in themselves or severally in any desired combination. In the drawings:
Figure 1 shows a sectional illustration of the carrier tile according to the invention, Figure 2 shows a diagrammatic top view of the carrier tile, Figure 3 shows an orthogonal sectional illustration of a carrier tile according to the invention in an installation situation for the decoupling of stress differences, and Figure 4 shows a diagrammatic sectional illustration of an alternative embodiment of the carrier tile in an installation situation according to Figure 1.
A carrier tile 11 according to the invention is illustrated in perspective in Figure 1. The carrier tile 11 consists of a plastic film which has a multiplicity of chambers 12 formed by depressions 14 of the plastic film. The chambers 12 are produced, for example, by vacuum forming or deep drawing. The carrier tile 11 has a multiplicity of chambers 12, which are arranged in a plurality of rows and columns or in defined patterns with respect to one another. Surface portions 16 which connect the chambers 12 to one another are formed between the depressions 14.
According to the first embodiment, wall portions 18 arranged perpendicularly with respect to these surface portions 16 extend from the latter and merge into a bottom 19 forming with an outer end face 21 a first tile side 22. The end faces 21 of the chambers 12 have glued to them a net-like fabric or nonwoven 23 which serves for cramping the carrier tile 11 in a contact layer applied to a base. The net-like fabric or nonwoven 23 is designed as a fine-mesh grid fabric or as a perforated nonwoven and is secured to the end faces 21 of the chambers 12 by means of an adhesive bond. The fabric or nonwoven is produced, for example, from polypropylene.
A second tile side 26 is formed, opposite the first tile side 22, by the surface portions 16 connecting the chambers 12. This tile side 26 has applied to it a further net-like fabric 27 or nonwoven which differs from the net-like fabric or nonwoven 23 applied to the first tile side 22. This net-like fabric or nonwoven 27 applied to the second tile side 26 is designed with a coarse mesh and is connected to the surface portions 16 by means of an adhesive bond or a welded joint. The net-like fabric 27 extends with its meshes over the depressions 14 of the chambers 12. Preferably, the net-like fabric 27 is produced from the same material as the carrier tile 11. For example, HDPE plastic is used.
The tearing or tensile strength of the fabric 27 is at least 250 N/5 cm. Furthermore, the fabric 27 preferably has an expandability of at least 5%, so that there is some elasticity for decoupling and in the event of temperature fluctuations.
The chambers 12 illustrated in Figure 1 have a circular bottom 19 and an end face 21 and are of column-like or - $ -cylindrical design. Alternatively to the round area in horizontal projection, triangular, square or polygonal areas in horizontal projection or lozenge-shaped or trapezoidal areas in horizontal projection may also be provided.
Figure 2 illustrates a top view of the carrier plate 11 according to the invention, as shown in Figure 1. The net-like fabric 27 on the second tile side 26 has a mesh width which makes it possibie to introduce mortar or adhesive into the chamber 12 virtually without obstruction. A mesh width of the fabric of at least 0.04 mm2 is preferably provided. For the easy introduction of a tile adhesive or mortar, in particular, a mesh width of 0.5 mm2 to 5 mm 2 is provided. That surface of the depression 14 which is to be covered is adapted to the mesh width of the fabric 27, so that at least two meshes overlap the depression 14. A sufficiently taut overlap of the depression 14 by the net-like fabric 27 thereby becomes possible.
Figure 3 illustrates a diagrammatic sectional illustration of the carrier tile 11 according to the invention, as shown in Figures 1 and 2, in an installation situation. An adhesive or mortar 32 is applied to a base 31. After this, the carrier tile 11 is laid out with the fine-mesh net-like nonwoven 23 on the base 31. The mortar 32 is cramped in the fine-mesh net-like nonwoven 23 which may be produced from a plastic or natural fibre material. The net-like nonwoven 23 is designed in such a way that, when the carrier tile 11 is laid out, there is no penetration of the mortar into regions 33. Air circulation in these free spaces 33 can thereby take place.
After the carrier tile 11 has been laid out and secured on the base 31, an adhesive or mortar 34 is introduced on to the carrier tile 11 and may deviate in consistency from the mortar or adhesive 32. In this case, the mortar 34 is introduced through the coarse-mesh net-like fabric 27 for filling into the chamber 12. At the same time, the mortar layer is hooked on the grid-like coarse-mesh fabric 27 which is provided on the surface portions 16. After this, tiles 36 for forming a surface cladding 37 are applied to the mortar layer 34. After the curing of the mortar 34, the surface cladding 37 is finished by the introduction of joints 38.
The mortar layer 34 forms, in the chambers 12, contact elements or mortar stilts which allow load dissipation.
Furthermore, shear forces which occur between the base 31 and the surface cladding 37 are decoupled by means of the carrier tile 11. The net-like fabric 27 crosses the mortar stilt and makes it possible to stabilize and stiffen the mortar stilt, since the net-like fabric 27 acts as a reinforcement. As a result, the strength of the bond can be increased, and at the same time the formation of cracks can be reduced due to the stress decoupling.
Figure 4 illustrates an installation situation of an alternative embodiment of the carrier tile 11 according to the invention. This carrier tile 11 deviates from the carrier tile 11 according to Figure 2 in the form of the chambers 12. The other features are identical, and therefore reference is made to the preceding figures. The carrier tile 11 according to Figure 4 has conical wall portions 18 which narrow towards the bottom 19. Thus, as seen in cross section, in the case of a round bottom 19 frustoconical chambers 12 are formed. Alternatively, triangularly or polygonally designed forms of the bottom 19 and of the depression 14 or orifice to the depression 14 may also be produced. As a result of the even slight reduction in the bottom area 19 with respect to the depression 14 in the region of the surface portion 16, the complete filling of the chamber 12 with mortar 34 can be facilitated. These cross-sectional forms of the chambers 12 likewise allow optimum load dissipation, a decoupling of stress differences and a reduction or prevention of the formation of cracks in the layer formed by the adhesive or mortar 34.
The inclination of the conically running wall portions is advantageously provided at an angle of less than . This optimizes force absorption, on the one hand, 15 and the filling of the chambers, on the other hand.
The net-like fabric covering the depression of the chambers is advantageously glued to the surface portions of the one tile side which connect the 20 chambers. As a result, different materials may be selected for the net-like fabric and for the carrier tile consisting of film-like plastic. Furthermore, gluing affords the advantage that the net-like fabric projects slightly with respect to the surface portions, and additional meshing with the adhesive or mortar layer adhering to the surface cladding becomes possible.
According to an alternative embodiment of the invention, there is provision for the net-like fabric covering the depressions to be welded to the surface portions connecting the chambers. It thereby becomes possible for the net-like fabric and the carrier tile to be connected, in the contact regions, so as to form a unit, with the result that very high strengths can be achieved. At the same time, the advantages of the glued-on embodiment of the net-like fabric can be preserved. Alternatively, there may also be provision for the net-like fabric to be embedded at least partially into the tile side during the welding-on process.
To produce a fusion-welded joint between the net-like fabric and the carrier tile, there is advantageously provision for the net fabric to be produced from a thermoplastic. Such thermoplastics are acid-resistant and have high strength.
According to a further advantageous embodiment of the invention, there is provision for the net-like fabric overlapping or covering the depressions to have a mesh width of at least 0.04 mmZ, in particular 0.5 to 5 mm`.
It thereby becomes possible easily to introduce or fill the chambers with an adhesive or mortar layer and with further flowable and curable materials. At the same time, however, it is ensured that a sufficient number of meshes overlap the depression or the chambers, in order to make it possible to fix the adhesive or mortar stilts within each chamber. Preferably, there is provision for at least two meshes to be provided for each chamber. The size of the chamber and the mesh width of the net-like fabric or nonwoven can in this case be adapted to one another so as to afford optimum cramping.
The net-like fabric for covering the depressions is preferably produced in the manner of a grid from rovings welded to one another. In this case, there is provision for the net-like fabric to have identical tensile strengths in both directions of the plane of extent, in order to allow a uniform stress reduction.
The rovings for the net fabric are preferably formed from twisted individual fibres, in order to have a high compressive strength.
According to a further embodiment of the invention, there is provision for the mesh width of the net-like fabric or nonwoven to be designed to be smaller than a surface portion between two chambers. As a result, at least two intersecting fibres of the fabric or at least one warp and one weft of the fabric can be welded or glued to the surface portion. The free orifice of the chamber can thereby be spanned by a tauter fabric or nonwoven portion.
The invention and further advantageous embodiments and developments of this are described and explained in more detail below by means of the examples illustrated in the drawings. The features to be gathered from the description and the drawings may be used, according to the invention, individually in themselves or severally in any desired combination. In the drawings:

A carrier tile 11 according to the invention is illustrated in perspective in Figure 1. The carrier tile 11 consists of a plastic film which has a multiplicity of chambers 12 formed by depressions 14 of the plastic film. The chambers 12 are produced, for example, by vacuum forming or deep drawing. The carrier tile 11 has a multiplicity of chambers 12, which are arranged in a plurality of rows and columns or in defined patterns with respect to one another. Surface portions 16 which connect the chambers 12 to one another are formed between the depressions 14.
According to the first embodiment, wall portions 18 arranged perpendicularly with respect to these surface portions 16 extend from the latter and merge into a bottom 19 forming with an outer end face 21 a first tile side 22. The end faces 21 of the chambers 12 have glued to them a net-like fabric or nonwoven 23 which serves for cramping the carrier tile 11 in a contact layer applied to a base. The net-like fabric or nonwoven 23 is designed as a fine-mesh grid fabric or as a perforated nonwoven and is secured to the end faces 21 of the chambers 12 by means of an adhesive bond. The fabric or nonwoven is produced, for example, from polypropylene.
A second tile side 26 is formed, opposite the first tile side 22, by the surface portions 16 connecting the chambers 12. This tile side 26 has applied to it a further net-like fabric 27 or nonwoven which differs from the net-like fabric or nonwoven 23 applied to the first tile side 22. This net-like fabric or nonwoven 27 applied to the second tile side 26 is designed with a coarse mesh and is connected to the surface portions 16 by means of an adhesive bond or a welded joint.

Alternatively to the round area in horizontal projection, triangular, square or polygonal areas in horizontal projection or lozenge-shaped or trapezoidal areas in horizontal projection may also be provided.
Figure 2 illustrates a top view of the carrier plate 11 according to the invention, as shown in Figure 1. The net-like fabric 27 on the second tile side 26 has a mesh width which makes it possibie to introduce mortar or adhesive into the chamber 12 virtually without obstruction. A mesh width of the fabric of at least 0.04 mm2 is preferably provided. For the easy introduction of a tile adhesive or mortar, in particular, a mesh width of 0.5 mm2 to 5 mm 2 is provided. That surface of the depression 14 which is to be covered is adapted to the mesh width of the fabric 27, so that at least two meshes overlap the depression 14. A sufficiently taut overlap of the depression 14 by the net-like fabric 27 thereby becomes possible.
Figure 3 illustrates a diagrammatic sectional illustration of the carrier tile 11 according to the invention, as shown in Figures 1 and 2, in an installation situation. An adhesive or mortar 32 is applied to a base 31. After this, the carrier tile 11 is laid out with the fine-mesh net-like nonwoven 23 on the base 31. The mortar 32 is cramped in the fine-mesh net-like nonwoven 23 which may be produced from a plastic or natural fibre material. The net-like nonwoven 23 is designed in such a way that, when the carrier tile 11 is laid out, there is no penetration of the mortar into regions 33. Air circulation in these free spaces 33 can thereby take place.
After the carrier tile 11 has been laid out and secured on the base 31, an adhesive or mortar 34 is introduced on to the carrier tile 11 and may deviate in consistency from the mortar or adhesive 32. In this case, the mortar 34 is introduced through the coarse-mesh net-like fabric 27 for filling into the chamber 12. At the same time, the mortar layer is hooked on the grid-like coarse-mesh fabric 27 which is provided on the surface portions 16. After this, tiles 36 for forming a surface cladding 37 are applied to the mortar layer 34. After the curing of the mortar 34, the surface cladding 37 is finished by the introduction of joints 38.
The mortar layer 34 forms, in the chambers 12, contact elements or mortar stilts which allow load dissipation.
Furthermore, shear forces which occur between the base 31 and the surface cladding 37 are decoupled by means of the carrier tile 11. The net-like fabric 27 crosses the mortar stilt and makes it possible to stabilize and stiffen the mortar stilt, since the net-like fabric 27 acts as a reinforcement. As a result, the strength of the bond can be increased, and at the same time the formation of cracks can be reduced due to the stress decoupling.
Figure 4 illustrates an installation situation of an alternative embodiment of the carrier tile 11 according to the invention. This carrier tile 11 deviates from the carrier tile 11 according to Figure 2 in the form of the chambers 12. The other features are identical, and therefore reference is made to the preceding figures. The carrier tile 11 according to Figure 4 has conical wall portions 18 which narrow towards the bottom 19. Thus, as seen in cross section, in the case of a round bottom 19 frustoconical chambers 12 are formed. Alternatively, triangularly or polygonally designed forms of the bottom 19 and of the depression 14 or orifice to the depression 14 may also be produced. As a result of the even slight reduction in the bottom area 19 with respect to the depression 14 in the region of the surface portion 16, the complete filling of the chamber 12 with mortar 34 can be facilitated. These cross-sectional forms of the chambers 12 likewise allow optimum load dissipation, a decoupling of stress differences and a reduction or prevention of the formation of cracks in the layer formed by the adhesive or mortar 34.
Claims (4)
1. Carrier tile consisting of a plastic film for a floor, wall or ceiling structure, for achieving decoupling between the base (31) and a surface cladding (37) to be applied to the carrier tile (11) which has a multiplicity of chambers (12) which are formed by depressions (14) out of a plane of the carrier tile (11) and outer end faces (21) of which form a first tile side (22), the depressions (14) being designed for receiving a curing contact means (34), such as mortar or adhesive, provided for forming a contact layer with the surface cladding (37) to be applied, and with a net fabric (23) or nonwoven arranged on the first tile side (22), characterized in that the chambers (12) between the first and an opposite tile side (22, 27) have an undercut-free wall portion (18), and in that a further net fabric (27) overlapping the depressions (14) is provided on the opposite tile side (26).
2. Carrier tile according to Claim 1, characterized in that the wall portions (18) of the chambers (22) are arranged vertically between those end faces (21) of the chambers (12) which form one tile side (22) and the surface portions (16) which connect the chambers (12) and which form the opposite tile side (26).
3. Carrier tile according to Claim 1, characterized in that wall portions (18) between those end faces (21) of the chambers (12) which form one tile side (22) and surface portions (16) which connect the chambers (12) and which form the opposite tile side (26) extend so as to narrow conically towards the end faces (21) of the chamber (12).
4. Carrier tile according to Claim 3, characterized in that the inclination of the wall portions (18) is less than 20° to the vertical.
