The rails are arranged parallel to each other and at a distance corresponding to a width of plate-shaped units (1), and bars are inserted between the dual-flanks. A supporting frame (5) is provided with rectangle profiles (51), where the arrangement of the profiles corresponds to the desired arrangement of the rails.

Description

The invention relates to a floor construction system for a surface to be occupied with plate-shaped elements each consisting of a flat cassette made of sheet metal with the ground directed from bevelled edge regions of the sheet formed webs, wherein the web is recessed in the corner region of the cassette; associated guide rails made of plastic with reverse cross-section T-shape, wherein the vertically arranged leg is formed as an upwardly open double edge, the guide rails are arranged parallel to each other and at a distance corresponding to the width of the plate-shaped elements and the two adjacent webs of two adjacent plate-shaped elements can be inserted between the double edge of the guide rail.

Such a floor construction system is from the DE 102 49 493 A1 known. This floor construction system is used for plane alignment of a floor covering, especially for outdoor use, which is non-destructively resumed and substantially prevents moisture accumulation and resulting impairments. The guide rails, which are elevated by means of spacer elements, allow drainage below the covering surface on the previously sealed underground. The glued on sheet cassettes tile or plate flooring is thus kept as free of surface water as possible. Nevertheless, it has been found in the known floor system, in particular in the raised with spacer elements construction variant that the guide rails, even when using metal profiles, do not have sufficient stability. In addition, the use of metal profiles for the guide rails undesirable due to unwanted noise when walking on and driving the laid covering.

Based on this prior art, it is an object of the invention to provide a floor system in which high traffic loads of at least 500 kg / m ^{2 are} permanently withstood by the system even with an elevated construction and at the same time noise resulting from the load is reduced or avoided.

In particular, created for relevant building codes balconies create undesirable barriers, since the water-bearing layer is at least 10 cm below the door threshold of the balcony door to arrange. There is therefore an increased need for elevated floor construction systems that allow accessibility while meeting building regulations on balconies.

According to the invention, it is therefore proposed that a support frame with rectangular profiles, on which the guide rails rest, is provided, wherein the arrangement of the rectangular profiles corresponds to the desired arrangement of the guide rails.

If the guide rails are glued to the rectangular profiles, the guide rail with the respective rectangular profile of the support frame virtually forms a composite element, on the one hand increases the rigidity of the system consisting of guide rail and rectangular profile and on the other hand maintains the achieved by the guide rail made of plastic noise attenuation. Preferably, the guide rails are glued to the rectangular profiles in shorter spaced-apart sections in order to improve the drainage of the lining layer. From the tiling in the slots between adjacent sheet metal cassettes running surface water passes in transverse joints, directly on the substrate prepared for water-proofing. On longitudinal joints, however, the surface water firstly enters the double flanks spanned by the guide rails. However, due to the guide rail divided into spaced-apart sections, an effective drainage of the surface water flowing in the double flanks to the ground is ensured. The sections of the guide rails have at least the length or preferably a multiple of the length of the sheet-metal cassettes. The guide rail free sections, however, are short compared to the side of the sheet cassette. Typically, the distances between longitudinally spaced guide rail sections are only 1 to 2 cm.

In order to ensure the dimensional stability of the parallel arranged rectangular profiles with glued thereto guide rails for accurately fitting insertion of sheet metal cassettes, the parallel arranged rectangular profiles are connected to each other via connecting profiles.

If the supporting frame is prefabricated in the dimensions for the subfloor to be laid, a particularly economic laying of the floor assembly system is achieved. For floor construction for balconies easily one-piece support frame can be made for example by template. For larger surfaces to be laid, several on-site zusammenfübare support frame elements can be provided. After aligning the one-piece or divided into a few sub-elements support frame on the ground can then be laid immediately passable without matching problems of the glued on the sheet metal tiles tile pavement.

In order to use the floor structure system to the edge of a surface to be occupied, the support frame is prefabricated in the dimensions of the surface to be laid.

Preferably, the cassette made of aluminum, Aluminiumzink- or stainless steel sheet and / or perforated plate. These materials are sufficiently rigid, resistant to environmental influences and easy to process with regard to the bending behavior. Cassettes made of stainless steel, for example with templates irradiated patterns can already be used as a finished end coating. Perforated metal cassettes serve, for example, as a cover via a drain arranged in the underground for the direct passage of surface water and / or as an additional decorative element.

Further, the cassette may be provided with a tile of ceramic, porcelain stoneware, clinker, concrete, glass, wood (parquet), carpet, linoleum, synthetic resin and / or natural stone, e.g. Granite or marble, be occupied. The respective coating is glued to the plate of the cassette. A glass cassette can also be prepared with a light source or connected optical fibers for lighting effects in the floor to be built.

Furthermore, it is also possible to produce cassettes which, in the central surface area, have an opening, for example square or circular, into which, for example, a drain screen or a glass insert is inserted for a light source. With suitable methods, for example by high-pressure water cutting, such cutouts can also be subsequently introduced into the cassettes provided with a covering. For example, in the case of a balcony floor structure, cassettes with drainage slots, which are covered with a tile, are used directly in front of the balcony door. Thus, it is certainly avoided that surface water could flow into the interior even when snow cover when opening the balcony door.

The fact that the covering thickness of the tile is greater than or equal to the clear height of the web of the cassette, it is achieved that the occupied with the tiles sheet cassettes for storage and transport are optimally stacked without the vertically downwardly facing webs undesirable forces, in particular be exposed in the horizontal direction, which could lead to a widening of the webs. The bars thus retain their correct vertical alignment even after a space-saving stacking and thus remain accurately inserted into the guide rails. The loads of the stacked plate-shaped elements are picked up by the tile covering and transferred over the flat part of the sheet cassette on the underlying tile covering.

If the light height of the web is smaller than the height of the flank, the ballast is not transmitted via the webs of the sheet cassettes on the guide rails and arranged underneath rectangular sections of the support frame in the installed state of the cassettes in the guide rails but on the flanks of the respective guide rails and the underlying rectangular profile. On the one hand, this has the advantage that the webs merely serve for horizontal coupling, that is to say for the horizontal concatenation of the floor covering, but themselves do not absorb any loads. A bending of the bars is thus extremely unlikely. On the other hand, this measure provides an additional drainage channel in the foot region of the double flank of the guide rail. The outflow of surface water is thus further favored.

Furthermore, the upper edge of the guide rails or guide rail sections adhered to the prefabricated support frame thus serves as a horizontally aligned support surface for the cassettes. Height tolerances of the webs cut off on the sheet metal cassette thus do not influence the altitude of the tile covering. Furthermore, so larger sheet metal cassettes, for example, for a central ornament ornament or so easily similar be provided, for example, has the size of 2 x 2 standard cartridges. Such enlarged cassettes then each have additional recesses on their bevelled webs for the bridged guide rail. The enlarged sheet cassette is then flat with its bottom on the flanks of the underlying guide rails.

Due to the fact that spacer elements, preferably made of an elastic hardening compound, are provided between the substrate and the supporting frame, an elevation of the floor construction system is achieved for bridging unevenness of the substrate and in particular for creating barrier-free covering surfaces adjoining, for example, balcony doors. If an elastically hardening mass with sufficient buoyancy, such as a mixed with Blähglaskügelchen synthetic resin mortar used, the prefabricated support frame can be placed on regularly applied to the substrate on the ground resin piles. The desired height and horizontal alignment is achieved by a suitable amount of the synthetic resin mortar and slight Justierschläge. The synthetic resin mortar cures relatively quickly, so that the covering surface is already loadable after about 2 to 3 hours.

Hereinafter, an embodiment of the invention will be described in detail with reference to the accompanying drawings.

In Fig. 1 is a plan view of a partially laid floor construction system is shown on a balcony with a trapezoidal floor plan. On a sealed for example with a liquid resin system substrate U balcony plate a support frame 5 are placed horizontally aligned by means of spacers 4. The support frame 5 is completely prefabricated and consists of longitudinally parallel to the building wall arranged rectangular profiles 51, which are arranged parallel to each other in accordance with the resulting from the cassette size grid spacing. The rectangular profiles 51 are connected to each other by means of connection profiles 52.

On the support frame 5 51 guide rails 2 in the form of plastic profiles, for example made of recyclate, Ethylenvenylacetat, PVC etc. are glued to the rectangular profiles. At the edge regions of the surface to be laid edge guideways 3 are also glued as angle plastic profiles on arranged underneath rectangular profiles 51 of the support frame 5.

In these prefabricated support frame 5 with attached (edge) guide rails 2 and 3, the cassette 11 formed as a sheet metal carrier are possibly used with tiled surface 12, for example, granite plates o. Ä., In the guide rails, wherein the folds 13 of the cassette 11 at each two edge regions in a groove formed between the double edges 21, 22 of the guide rail 2 dip groove 23 or the flank 31 a Overlap edge guide rail 3. Bends 13 aligned transversely to the longitudinal extent of the guide rails 2 and 3 stiffen the sheet-metal carrier 11 which bears freely in this direction.

In Fig. 2, the built-up on a balcony floor system according to FIG. 1 is shown with the connection to a balcony door T. The rectangular profiles 51 of the support frame 5 are placed on spacers 4, so that the floor structure is oriented horizontally and aligned heightwise elevated to the threshold height of the balcony door T. The spacer elements 4 are formed in particular from a synthetic resin mortar 4. In this case, a Kunstharzmörtelhäufchen 4 is applied to the substrate U at regular intervals and then placed on the rectangular profiles 51 of the support frame 5 and aligned horizontally. After setting of the synthetic resin mortar of the support frame 5 with the guide rails mounted thereon 2 and 3 permanently aligned horizontally and resilient.

FIG. 3 shows in detail a cross-section through a rectangular profile 51 with guide rail profile 2 glued thereto and (two sections) two engaging plate-shaped elements 11. The guide rail has an inverted T-shaped cross-section, wherein the upwardly directed leg of the guide rail 2 has two mutually parallel flanks 21, 22 has. The double flank 21, 22 forms a groove 23 with a bottom 24. For the outflow of surface water running therein, the guide rails, as shown in Fig. 1, divided into longitudinally spaced portions, the short distances drainage holes 25 to the expiration of in the Groove 23 recorded surface water on the underground U serve.

Of course, it is also conceivable that in the parallel flanks 21, 22 of the guide rail 2 near the bottom 24 arranged holes or slots are provided for drainage.

In Fig. 4, an edge guide rail 3 is glued to a rectangular profile 51 of the support frame 5 with hinged plate-shaped element 1 in cross-section. The edge guide rail 3 is an angle profile of the same material as the guide rail 2. Substantially corresponds to the edge guide rail 3 between the double flank 21, 22 in the longitudinal direction halved guide rail 2. The edge guide rail 3 has a vertically upwardly directed edge 31 and a horizontally oriented base 32, which is glued on the rectangular profile 51.

Fig. 5 shows a plate-shaped element 1 in a spatial view obliquely from below. The plate-shaped element 1 consists of a cassette 11 and a tile 12 applied on the upper side of the cassette 11, for example a ceramic tile or natural stone tile. The cassette 11 is designed as a preferably rectangular sheet-metal carrier, with all four edge regions of the sheet-metal carrier having the webs forming folds 13. The adjacent folds 13 stiffen the sheet metal carrier 11 and also serve to fix the position of the plate-shaped elements 1. Two adjoining plate-shaped elements 1 dive with their abutting folds 13 precisely into the groove 23 of the double flank 21, 22 of the guide rail 2, as shown in Fig. 3rd is shown. The width of the groove 23 corresponds to twice the material thickness of the sheet metal support 11 plus a tolerance measure. For example, can be used as a material for the sheet metal support Aluminiumzinkblech with a thickness of 1.8 mm. The clear width of the groove 23 of the double flank 21, 22 should then be 4 mm.

The folds 13 are recessed at the corners of the cassette 11. These provided at the corners of the cassette 11 recesses 14 are so chosen that the continuous edges 21 and 22 of the guide rail 2 and by the edge 31 of the edge guide rail 3 are not disturbed by the transversely to the longitudinal extent of the guide rail 2, 3 arranged folds 13. Preferably, the recesses 14 are selected so that the flanks 21, 22 or 31 received therein are enclosed on both sides by the folds 13 only with little play. In order to allow any orientation of the elements, in particular in the case of square plate-shaped elements 1, the recesses 14 are trained rotationally symmetrical to one another.

The plate-shaped elements 1 preferably have a square surface extension, in particular with a dimension of 300 × 300, 350 × 350 or 400 × 400 mm 2. In addition, individual larger cassettes can be used for special design solutions that cover, for example, an area of 2 x 2 standard cassettes 11. In this case, 11 recesses for the bridged by the enlarged cassettes guide rails 2 are provided in the folds of these larger cassettes according to the division of the standard cassettes.

With the floor construction system according to the invention sufficiently stable raised surface areas can be created for usual traffic loads. The flooring allows the passage of surface water onto the previously sealed subsoil supporting the structure for drainage of the surface. Particularly in the case of balcony renovation, barrier-free access from the balcony covering to the balcony door can be created with such a floor construction system.
