Description

Baubereichsbahn

The present invention relates to the laying of tiles. It relates to the use of a construction area railway as a laying substrate for tiles. It relates to a method for laying tiles. It concerns a tile composite and floor surface construction, which includes tiles.

In the construction sector, in particular wall and / or floor surfaces with tiles, plates, natural or artificial stones, such as. Agglo marble, which can be used both indoors and outdoors.

Although tile laying has long been established and practiced, it still suffers from problems. Common problems with tile laying are e.g. in dealing with cracks or unevenness of the surfaces to be tiled. In order to overcome such problems, in part tile construction works are used.

Thus, the German Patent Application DE 10 2008 045 122 A1 proposes in the prior art a moisture-permeable tiling mat with a moisture-absorbing layer at least 1 mm thick, wherein the tiling mat has an upper side and a

Bottom and a plurality of recesses extending from the top toward the bottom. Tile laying mats, one at the bottom

However, are not described nubs structure.

Based on this prior art, it is the object of the present invention to provide a simple way of Tiles, but which in particular still allows to deal with tiling with cracks or bumps on the surfaces to be tiled, high tensile strength of the tile tiles to the ground achieve, so that a tight fit of the tile is guaranteed to compensate for underground tensions and

Avoid moisture build-up under the tiles.

Surprisingly, it could be found in the context of the present invention that this object is achieved by the subject matter of the invention. This is due to the use of a

Baubereichsbahn, which at the top of a nonwoven, fibrous or felt layer and is provided on the bottom with knobs, as a substrate for laying tiles. The term "tile" in the sense of the invention comprises in particular all hard coverings of ceramic, stone, natural stone, artificial stone, etc., which are in principle suitable for being used as wall and / or floor coverings, in particular ceramic wall components - and / or floor coverings of clay, kaolin, sand and other mineral raw materials.

Furthermore, the term "tiles" also shaped floor coverings made of textile or

Plastic material includes, or from other materials, such as wood, which here as an example called carpet, PVC and wood tiles are called. As an artificial stone mineral (eg cement and / or lime) or resin-bound materials are referred to, which were produced with aggregates of, for example, sands and broken rocks. For example, Agglo marble is an industrially manufactured stone that consists of 95% marble fragments and calcium carbonate and is bound with polyester resin. The term "tile" also includes so-called "tiles" and plates. For the purposes of the present invention, each tile format can be used, such as the former dominant wall tile format with 15 x 15 cm. In the meantime, particularly large tiles, for example, with a size of 120 ^χ 120 cm and beyond, are also offered, these are also used in the context of the invention. However, tile formats which can preferably be used are, for example, between 25 ^× 33 cm and 30 ^× 90 cm, in particular for wall tiles and, for example, between 33 × 33 and 45 × 90 cm, in particular for floor tiles.

The use of the invention makes it possible when tiling with cracks or

To avoid unevenness of the surfaces to be tiled, since the material design of the

Nonwoven fabric, fibrous or felt structure construction naps and naps cooperating to compensate for such bumps and to bridge cracks.

Furthermore, a high adhesive tensile strength of the tiles using conventional bonding materials, such as in particular mortar, concrete and / or adhesive, can be realized to the Baubereichsbahn whose top has a nonwoven, Faserflor- or felt layer. The high adhesive tensile strength is attributable to the nonwoven, fibrous or felt layer of the construction area web, which has a large number of individual fibers and, accordingly, a particularly large adhesive surface. This ensures a particularly tight fit of the tiles on the Baubereichsbahn.

Typical adhesive pull values for commercially available tile laying mats are <0.3 N / mm ² , the system according to the invention allows values> 0.5 N / mm ² . Existing decoupling and

Drainage systems generally have weaknesses in combination with conventional bonding building materials, such as in particular thin-bed mortar, namely weaknesses in terms of curing and in relation to the composite binding agent / decoupling and drainage mat. The present invention on the other hand guarantees a very good adhesion.

Furthermore, the inventive use of Baubereichsbahn allows to compensate for underground stresses. Underground stresses are generally difficult to avoid in the construction sector. For example, concrete can undergo changes in shape due to creep and shrinkage even months or even several years later, causing tension. Occurring underground tensions can then usually be transferred to the tile covering and subsequently lead to cracks. This is prevented by the present invention, since any background stresses are compensated by the Baubereichsbahn. In general, vibrations or shifts or movements of the ground can be intercepted and compensated so that they are not transferred directly to the tiles. These advantages are also due to the interaction of nonwoven, batt or felt structure and nubs.

In addition, the present invention makes it possible to avoid moisture congestion under the tiles. Moisture accumulating under the tiles is particularly harmful as it can damage the bond. The material design of the Baubereichsbahn from nonwoven,

Fibrous or felt structure and nubs but makes it possible to remove any moisture to the side, so that an excellent drainage function is given because accumulating water such. Rainwater, is led away. In this way, possible frost damage is counteracted outdoors.

Yet another advantage of the present invention is that it can be combined with a

Sound reduction is accompanied and allows particularly good impact sound. A separate impact sound insulation is therefore no longer necessary.

Yet another advantage of the present invention is that it is associated with thermal insulation. Separate thermal insulation is therefore no longer necessary.

The advantages of the present invention are when used both in the indoor and in the

Outdoor area (eg in the balcony and patio area) achievable. The solution according to the invention is characterized in particular by a very good weather resistance, but especially by frost and in particular by its very good UV resistance. Especially The pronounced UV resistance predestines the construction area web according to the invention for outdoor use. The UV resistance is particularly in the edge regions of the installation structure of great advantage. The use according to the invention of the construction area track in the outer area thus corresponds to a particularly preferred embodiment of the invention. A particular advantage of the present invention further lies in the fact that it solves technically demanding tasks, for example, produces impact sound insulation, acts as a heat-insulating agent, compensates for cracks or unevenness, enables high adhesive tensile strengths, fulfills a moisture removal function, has stress-compensating effect, has high UV resistance, and makes it possible to lay tiles on unsuitable and problematic surfaces, both indoors and outdoors, without the risk of damage. On the other hand, the particular simplicity of the solution according to the invention. While commercially available tile-laying mats have a particularly complex construction, the present invention can be implemented with comparatively simple means. For the purposes of the invention, in principle so-called artificial turf with nubs on the underside can be used, as it is available in hardware stores as meter goods, for example, as synthetic turf carpet. It has surprisingly been found by the inventors that already such

Hardware products within the meaning of the invention can be used. That artificial turf carpets for

Tile laying can be used and even able to solve technically demanding tasks is surprising and was previously unknown. Previously, such grass carpets were used only as a simple ground cover. e.g. on Baikon or in

Conservatories. The present invention to be used Baubereichsbahn can also be laid in particular floating, ie without permanent attachment to the ground and thus allows a simple dismantling if necessary.

The building material web to be used according to the invention is in particular permeable to air. The building material web to be used according to the invention is in particular permeable to moisture, the term moisture encompassing both water and water vapor. The

Baubereichsbahn is preferably permeable to moisture from top to bottom as well as from bottom to top.

The building material web to be used according to the invention is characterized inter alia by the fact that the underside is provided with nubs. These nubs can basically be made of any materials. In the context of a preferred embodiment of the invention, however, it is preferred that the nubs are made of polymers, preferably of polymers having elastic properties, in particular of vulcanized natural or synthetic rubbers. Elasticity is the property of materials to react reversibly to an acting force. The advantage of using rubbers is that they are at higher temperatures and / or under influence

deforming forces show a viscous flow. They can therefore be processed in a very simple manner shaping. Of course, the nubs can also off

thermoplastic polymers, in particular polyvinyl chloride, polyethylene, polypropylene, polyethylene terephthalate and / or polyamide. In general, those materials are particularly preferred which pass by melting or plasticizing in a flowable state or plastically deformable state. In the simplest form, the nubs can thus by shaping melting a corresponding material, in particular

Polymers are applied to the bottom. The technology required for this is trivial, as proven not least by the good availability of synthetic turf carpets with such nubs.

Particularly preferred dimpled materials are natural rubber, nitrile rubber (NBR, acrylonitrile-butadiene rubber), chloroprene rubber, styrene-butadiene rubber, isoprene rubber, silicone rubber, fluorocarbon polymer, ethylene-propylene elastomers,

Polybutadiene rubber, PE (preferably PE foam), PU (preferably PU foam), PP (preferably PP foam), PVC foam and / or EPDM rubber (ethylene-propylene-diene copolymer). In particular, it is advantageous to use a soft-elastic polymer material with a pore structure based on natural rubber.

It corresponds to a preferred embodiment of the invention, when the knobs each have a width of 0.2 to 5 cm, preferably 0.3 to 2 cm, in particular 0.4 to 1 cm, and a height of 0.1 to 5 cm, preferably 0.2 to 1 cm, in particular 0.2 to 0.5 cm. The exact design of the knob size is based on the needs of the consumer. For conventional tiles and plates in particular such knobs have proven, which

preferably have a maximum width of 1 cm and a minimum width of 0.4 cm, and preferably have a maximum height of 0.5 cm and a minimum height of 0.2 cm. In this way, particularly good results in terms of impact sound insulation, equalization of cracks or bumps moisture removal function,

Cause voltage compensation. The studs are preferably shaped to have their widest point immediately where they are in contact with the underside of the construction web and then away from the body

Progressively rejuvenate the construction sector. The shape of the dimples essentially corresponds in this case to a shape that approximates a straight circular cone, an oblique circular cone or a truncated cone, i. the end of the nub pointing away from the structural web is preferably the narrowest point of the nub.

Likewise, it has proved to be particularly advantageous if the construction area web to be used according to the invention advantageously has 15 to 60 nubs per square decimeter, preferably 20 to 55 nubs per square decimeter, in particular 30 to 50 nubs per square decimeter. This too is very helpful for achieving particularly good results in terms of footfall sound insulation,

Adjustment of cracks or bumps, moisture removal function,

To cause voltage compensation, in particular in combination with the previously described knob size.

It is therefore particularly preferred if the nubs are made of polymers, preferably of polymers having elastic properties, in particular of vulcanized natural or synthetic rubbers, and advantageously a width of 0.2 to 5 cm, preferably 0.3 to 2 cm, in particular 0.4 to 1 cm, and a height of 0.1 to 5 cm, preferably 0.2 to 1 cm, in particular 0.2 to 0.5 cm, and thereby the Baubereichsbahn advantageously 15 to 60 nubs per square decimeter, preferably 20 to 55 nubs per square decimeter, in particular 30 to 50 nubs per square decimeter.

It has also proven to be advantageous if the distance between the individual knobs of Baubereichsbahn advantageously at least 0.2 cm, preferably at least 0.5 cm, in particular at least 0.8 cm or even at least 1 cm. In this case, the distance, measured from the outer edge of a knob to the outer edge of the nearest knobs, meant by the distance, said outer edge of the knob that outer edge is meant, where the knob is still directly in contact with the Baubereichsbahn. Such a nub arrangement is helpful for achieving particularly good results with regard to the moisture removal function, but also with regard to impact sound insulation, equalization of cracks or unevenness, stress compensation, in particular in combination with the previously described

Nub size and number of nubs per square decimeter. It has also proven to be advantageous if the distance between the individual knobs of Baubereichsbahn is not more than 4 cm, preferably at most 3 cm, in particular at most 2 cm or even at most 1, 5 cm. In this case, the distance, in each case in turn, the distance measured from the outer edge of a knob to the outer edge of the nearest knobs meant by outer edge of the knob that outer edge is meant where the knob is still directly in contact with the Baubereichsbahn. Such a nub arrangement is helpful in achieving particularly good results in terms of the stated advantages, such as moisture removal function, in particular in combination with the above-described nub size and number of nubs per square decimeter.

The building material web advantageously has a total thickness of 0.2 to 5 cm, preferably 0.3 to 1, 5 cm, in particular 0.5 to 0.9 cm. The total thickness also includes the height of the nubs on the track.

According to the invention the Baubereichsbahn on the upper side on a nonwoven fabric, Faserflor- or felt layer and is provided on the bottom with nubs. In this case, according to a preferred embodiment of the invention, the nonwoven, fibrous felt or felt layer, but in particular the nonwoven layer, can be formed from synthetic fibers, preferably comprising polyolefin fibers, in particular comprising polypropylene fibers.

Also, chamfers of natural polymers, e.g. Cellulose, usable. Fibers of synthetic polymers, e.g. Polyolefin fibers, but are preferred. Furthermore, in particular fibers based on polyamide, polyester, PET (polyethylene terephthalate), PBT

(Polybutylene terephthalate), PVC (polyvinyl chloride), PPS (polyphenylene sulfide), PAN (polyacrylonitrile), PI (polyimide), PTFE (polytetrafluoroethylene, Teflon), aramids, polyamide-imide and fiber blends.

It can also be used a felt layer. Felt is known. It is a textile fabric made of a disordered fiber, thus a non-woven textile with random arrangement of the fibers, which can be natural and man-made fibers. Felt is preferably produced from chemical fibers and, in principle, also from vegetable fibers, for example by dry needling (so-called needled felt) or, for example, by solidification with water jets emerging from a nozzle beam under high pressure. Fibrous webs can also be used with preference. According to DIN ISO 9092: 1988-05 or CEN Standard DIN EN 29092: 1992-08, the batt belongs to the so-called

Nonwovens. It is a structure of directed or randomly oriented fibers, solidified by friction and / or cohesion and / or adhesion.

In principle, it is also possible to use all fiber products which do not fall under the abovementioned generic terms nonwoven, felt, batt, and which are described, for example, in US Pat. woven, knitted, knitted, tufted or stitched with the inclusion of binding yarns or filaments.

In particular, however, it is preferred that the upper side of the construction region web has a nonwoven, fibrous or felt layer with at least a partial loop structure, in particular a nonwoven fabric layer. The nonwoven, Faserflor- or felt layer can also be designed in regularly predetermined orientation. However, a random fiber structure leads to even better adhesive properties.

According to a preferred embodiment of the invention, the mass density of the nonwoven, Faserflor- or felt layer is in the range of 500 to 3000 g / m ² , preferably in the range of 750 to 2500 g / m ² , in particular 1000 to 2000 g / m ² . The mass occupation or area-related mass is the ratio of mass and area of a layer. The metric unit is g / m ² .

The construction area web can absorb, store, divert and distribute moisture in its nonwoven, fibrous or felt layer. The building material web is preferably movable so that it can be rolled up.

According to a further preferred embodiment of the invention, at least individual fibers of the nonwoven, fibrous or felt layer can be hydrophilized, for example by adding a hydrophilizing additive. For example, larger portions of the fibers of the nonwoven, fibrous or felt layer may also be hydrophilized, eg more than 50% of all fibers of the nonwoven, fibrous or felt layer. Hydrophilization of the fibers can lead to a further improvement in the adhesive tensile strength. Hydrophilization additives are known per se, such as, for example, cationically modified polysiloxane compounds. It is a preferred embodiment of the invention, when the construction area web has a monolayer structure comprising a nonwoven, batt or felt layer, one side of the nonwoven, batt or felt layer being immediately napped

in particular directly applied to the nonwoven, Faserflor- or felt layer, in particular were melted.

Single-layer construction thus means that the entire construction range of a single

Nonwoven, fiberboard or felt strips, with the nubs are placed directly on one side of this strip. There, where the pimples are not put on, you look directly at the actual nonwoven, felt or felt strips. This setup is very simple but still very effective in its effect.

It corresponds to a further preferred embodiment of the invention, when the construction area web has a two-layer structure comprising a nonwoven, fibrous or felt layer, wherein one side of the nonwoven, fibrous or felt layer is provided directly with nubs, which in particular on the nonwoven, Fibrous or felt layer have been melted, wherein the material from which the knobs are formed, also the same side on which the knobs are located, at least partially covered. This secondary layer on the nonwoven, fiber pile or felt strip preferably has a small thickness, in particular in the range of 0.05-0.2 cm. Also, this structure is inexpensive to implement. The secondary layer is especially permeable to moisture and air.

Within the scope of the use according to the invention, it is provided that the tiles are fixed on the construction area web by using suitable binding materials. It corresponds to a preferred embodiment of the invention that for fixing the tiles on the

Baubereichsbahn Bindebaustoffe, in particular mortar, concrete and / or adhesive, such. Thin or Mittelbettkleber be used. Medium-bed adhesives are, in particular, those tile adhesives which can be applied over the entire surface with layer thicknesses of 2 to 15 mm. Thin-film adhesives are, in particular, those tile adhesives which can be applied over the entire surface with layer thicknesses of 2 to 6 mm.

It is thus preferred in the context of the use according to the invention to apply to the surface to be tiled a Baubereichsbahn as described above, the knobs of Baubereichsbahn rest on the surface to be tiled on the top of

Baubereichsbahn Bindebaustoffe, in particular mortar, concrete and / or adhesive to apply, and then place the tiles on the binder building layer. The application of the Baubereichsbahn on the surface to be tiled can be done in particular in loose form, according to the laying of a carpet. Likewise, it is still possible to attach the Baubereichsbahn to the tiling Untergund. For this purpose, recourse can be had to conventional fastening means, for example to binders, in particular adhesives. Likewise, other fasteners can be used, for example, the Baubereichsbahn on a

Wooden background, e.g. Wooden floor, to be fixed by nailing.

Optionally, a watertight sealing membrane can be introduced between the construction area web used according to the invention and the substrate, in particular when used in the outer area. In this case, the watertight waterproofing membrane is first applied to the substrate. The application of the watertight sealing sheet to the substrate to be tiled can be carried out in particular in loose form, in accordance with e.g. laying a carpet. It is also possible to attach the Baubereichsbahn to the tiling to underground. For this purpose, use can be made of conventional fastening means, in particular adhesives. On the optionally used waterproof waterproofing membrane, the construction area web used according to the invention is again applied, as described above, in particular in loose form. In principle, any waterproof waterproofing membrane can be used. A preferred material basis for the optional waterproofing sheet is polyethylene.

In particular, in the context of the present invention, polyethylene films, preferably nonwoven-laminated polyethylene films, have advantageously been used on both sides of nonwoven-laminated polyethylene films. The preferred layer thickness of such a polyethylene film is about 0.1 mm to 1.5 mm, preferably 0.2 to 1 mm. e.g. 0.4 mm. In particular, the use of a two-sided

Fleece-laminated polyethylene films in conjunction with the other features of the invention to particularly good results in view of the already pointed out technical advantages, such as in particular the drainage function, decoupling effect, impact sound insulation and thermal insulation. As an alternative to the optional waterproof waterproofing membrane can

especially in the interior optionally also be used on so-called installation panels. These are preferably made of plastic-fiber mixtures. Suitable plate thicknesses are preferably in the range of 3 to 25 mm, preferably 4 to 15 mm.

Of course, the present invention to be used Baubereichsbahn not only be used on walls and floors, but also on ceilings, stairs, etc. The building material web to be used according to the invention can in principle be used on all conceivable substrates, in particular cement screed, calcium sulphate screed, heating stripe (screed is a mineral screed floor construction known to the person skilled in the art, which is provided with heating elements for underfloor heating), cast iron screed, concrete, plastic substrate, chipboard, (old) ceramics, tiles, slabs and natural stone coverings and / or wooden floorboards.

In the method according to the invention, in particular, the application of the

Baubereichsbahn can be done on the surface to be tiled especially in loose form, according to the laying of a carpet. It is also possible to attach the Baubereichsbahn to the tiling to underground.

The advantage of the method lies in its simplicity. Namely, in the simplest embodiment, it is sufficient to take an artificial grass carpet, such as is available in the hardware store by the meter, to apply to the base surface to be tiled with the nub side down, with the optional use of a fastener, such as adhesive, the top of Artificial grass carpet with a binding building material, such as mortar in particular, to provide and lay on it in otherwise usual way the tiles. The artificial grass carpet or another inventively usable construction range web can previously be easily cut, for example, with a pair of scissors.
