Description

The The invention relates to a floor construction system for a surface to be occupied with plate-shaped Elements and associated support elements, wherein the support elements are laid on the ground and for plane alignment the plate-shaped Serve elements, wherein on the plate-shaped elements at two opposite edges provided to the ground webs are provided, the support elements as guide rails with two mutually parallel and upwardly open flanks are designed as double edges, the guide rails in parallel and at a distance corresponding to the width of the plate-shaped elements are arranged to each other and the two adjacent webs of two adjacent plate-shaped Elements between the flanks of the guide rail can be inserted

Such a floor construction system is as a so-called cavity floor for the pure interior use of the DE 195 27 303 A1 known. This cavity floor is used indoors for the creation of receiving spaces for installation cables. In this case, raised floor panels are mounted on a stand assembly spaced from the interior floor. The stator assembly consists of supporting beams, for example of mineral material, which are leveled by means of mortar. Furthermore, the raised floor panels are tightened by screwing, nailing or gluing with the support beams and thereby form a uniform, leveled wing.

A similar floor, suitable for interiors, is from the DE 31 44 815 A1 in which special provisions are made for catching liquid possibly passing through the bodywork by providing a so-called large gutter.

such Superstructures are for Building exteriors not applicable, since just a permeability of the soil structure system for drainage on the underlying surface to be occupied is wanted and accordingly also an occasional picking up of the floor slabs possible for cleaning the substrate have to be.

Therefore are for Building exteriors Floor construction systems for covering concrete surfaces, for example balconies known, the surface to be coated a seal, for example with Plastic sheets, liquid resin or bitumen. On it small mortar bags in the distance to be laid Pavement plates placed and laid out the sidewalk plates and aligned. For any Maintenance or repair purposes The surface can be removed on the ground, but this is for the usually used pavement slabs very laborious. Further is disadvantageous that leaves and Dirt largely unhindered by the relatively wide joints in the Cavity under the plates. There these particles collect, accumulate moisture and lead too undesirable Algae and moss growth as well as an odor nuisance.

Further is under the brand name "KERA-Flex" a topping for sealed substrates from BSW Berleburger Schaumstoffwerk GmbH, 57301 Bad Berleburg known, in which on the ground a plate-shaped insulation pad a polyurethane rubber building material is placed on and in the Bonded tiles are glued. On the underside of the insulating layer Although a profile for horizontal drainage is provided, nevertheless gets through the insulation layer the moisture is kept on the ground. Adequate ventilation is due to the extremely low Cross sections not possible. Consequently, unwanted arises Algae growth. About that addition, it is disadvantageous that the Flooring not nondestructively added can be, because insulation pad and tiles are glued together in a composite.

Furthermore, the DE 200 05 249 U1 a tile system for resealable laying of tiles is known in which on the bottom of each tile is provided with a plugged Bodenstelzplatte and form tile and Stelzplatte a composite element. The connectors of the Bodenstelzplatte serve for releasable coupling of adjacent tiles and form a surface connection of the floor covering. Although this floor covering is resumable, however, made of plastic, tile-sized Bodenstelzplatten allow no individual ground leveling for horizontal alignment of the flooring on an uneven and / or sloping underground. The load of the tile covering is transferred over the Bodenstelzplatte surface to the ground. Accordingly, the Bodenstelzplatte the composite element should lie substantially full surface, otherwise there is a risk of tile breakage.

From the DE 42 33 175 A1 is a plate-laying system for floors, especially outdoors, known in which the plates are placed on mounting rails, wherein the support rails have channels for collecting and discharging liquid. The carrying device consists of longitudinal rails and cross rails, which together form a very complicated structure.

Furthermore, from the DE 23 33 005 A1 a floor slab for a raised floor with a wood plate, which is covered on its underside with a sheet metal, in which the wooden plate is additionally covered on the sides with a fire-resistant metal and reinforced with downwardly projecting metal flanges. This circumferential, projecting metal flange engages in its corner areas in an upper part of punctiform supports. However, these floor supports have the disadvantage that they bring punctiform loads on the ground under heavy weight load. Furthermore, a subsequent alignment, so moving the inserted floor panels is not possible.

outgoing From the above-mentioned prior art, it is the task of Invention to provide a floor assembly system that is easy to level can be, non-destructive is again absorbable and as far as possible from a moisture accumulation and resulting vegetation is protected.
