Description

The invention relates to a floor structure system, arranged on a base floor on feet U-shaped support rails whose free legs are aligned towards the base floor, and the grid-like spanning the surface of a support floor is suitable for laying floor slabs and / or natural stones, so that these the base floor laid floor panels and / or natural stones opposite the base floor form a double floor.

In the prior art is a floor construction system for outdoor use in the DE 4 233 175 A1 described above, in which are provided as support means for the plates mounting rails, which are formed as a network with longitudinal and transverse rails, wherein the cross rails are arranged on the longitudinal rails. In this case, this floor construction system is provided in particular for the installation of balcony and terrace slabs. The disadvantage of this floor construction system is that unevenness of the base floor can be compensated only by placing spacer plates in place, so that as flat a base floor as possible is the basic requirement for laying the panels of a flat double floor.

From the DE 10 249 493 B4 is a floor construction system known which can be used even on uneven ground floor. In this solution, the guide rails for receiving the plates of the double bottom are placed on aggregates of synthetic resin mortar and aligned horizontally. This process requires a great deal of experience for planar alignment of the surface of the false floor, and is the more difficult the larger the raised floor areas are to be aligned, especially since a subsequent correction of the guide rails after the resin mortar has cured, is no longer possible.

In addition to the above-mentioned, especially for outdoor use, such as terraces, balconies, etc., provided floor construction systems, floor construction systems for indoor use are described in the prior art. In the interior, the construction of raised floors is usually also connected with an intended creation of receiving spaces for installation lines ö. Ä. Under the floor.

Preferred areas of application for the use of such raised floors are offices, where the space under the raised floor serves to accommodate a variety of installations.

In these intended for indoor solutions, the guide rails are made of sheet steel. The guide rails themselves are arranged on support legs made of steel. Therefore, all these solutions are inevitably only suitable for indoor use because of the susceptibility to corrosion of the guide rails and the support feet.

For example, such designs are in the DE 29 42 257 A1 , of the DE 85 31 810 U1 , the generic DE 41 32 989 A1 , of the EP 1 247 922 A2 and the DE 20 2011 109 402 U1 described above.

The support feet used in these solutions are designed by means of filigree screws and / or arranged in threaded sleeves threaded rod and with these to secure the position in operative connection passing locknuts height adjustable. At the top of the, adjustable in height support legs made of steel, guide rails are also made of steel, by means of small screws and nuts under the given connection angles of 90 ° or a multiple of 90 °. In the solution after the EP 1 247 922 A2 The guide rails can also be mounted at a multiple of 45 ° on the height-adjustable support foot.

All support legs described in the aforementioned solutions is common, however, that with uneven base floor whose bearing surfaces relative to the base base, the bearing surfaces of the support legs, must be aligned by chocks so that the center axes of the support legs are positioned perpendicular to the later floor level of the raised floor.

To overcome this latter drawback, prior art support systems for raised floors, i. Floor system described above, in which the support leg is pivotally mounted by means of a ball joint between the base floor and the double bottom.

Such solutions are for example in the US 3,318,057 A , of the GB 1 209 007 A , of the DE 91 01 717.3 U1 , of the GB 2 347 152 A , of the ES 2 326 056 A1 and the KR 101217358 B1 described above.

But even with all these solutions are again solutions with metal machine screws with a variety of loseable, assembly-intensive small parts, such as screws, nuts, washers and retaining rings that always require the appropriate installation tool and inevitably require a high assembly cost.

In addition, all the aforementioned solutions have in common that the respective solution associated guide rails are prefabricated so that they always enforce a predetermined pitch. Each individual adaptation of the floor to the space geometry present in / on the structure requires individually produced guide rails (for example in the area of the wall connection in the respective room), which inevitably results in a high additional installation effort.

Particularly expensive is the mounting of the support rails on the feet especially whenever, for example, the corners of the deviate from 90 ° in each room and also do not represent a multiple of 45 °.

Based on the aforementioned prior art, the present invention seeks to develop a corrosion-resistant both for indoor use as well as for outdoor use soil structure system, which eliminates the aforementioned disadvantages of the prior art, while the structure of a support floor for the raised floor in any infinitely Heights, even with respect to a "sloping" or uneven base floor should allow, the support floor should be easily adaptable both in its length as well as in its width, but also in its corner angles continuously to the respective room geometry, and the floor to be developed system even under unfavorable Boundary conditions should always be heavy duty, stable and reliable, while at the same time should be easy, simple and inexpensive to transport, also always simple, fast, reliable and safe to install, and should also be easy and inexpensive to produce, with Construction and / or stabilization of the spanned by the floor construction system support floor by no means a variety of different filigree items, such as washers, nuts, or the like. May apply.
