Description

Technical area

The present invention relates to a substructure for supporting an elevated, accessible area, in particular terrace areas or other floor surfaces, according to the preamble of the first claim.

Usually, the raised, accessible area is formed by a plurality of decking boards or patio slabs.

State of the art

Are known from the prior art bearing structures or support devices on which support beams of a substructure for the establishment of elevated, accessible surfaces. In this case, there is typically a large number of decking boards or terrace panels directly on the support beams.

For example, is from the DE 10 2013 109 845 A1 a pedestal bearing serving as a support device known as part of the substructure, wherein the support beam is height adjustable by means of the pedestal bearing. Such pedestals are used to lay the large number of terrace plates without mortar and thereby create between terrace plates and ground cavity, through which the surface water such as rainwater can drain. The water passes through the open (not grouted) plate joints under the terrace surface and is there derived via a slope of the substrate or drainage mats.

Such pedestals allow in a simple way a height adjustment of the supporting beams and thus the overlying terrace area.

That in the DE 10 2013 109 845 A1 shown pedestal bearing has a rotatable, manually operable intermediate member with two oppositely acting threads, which engages in an upper support part and a lower bottom part. The upper support part is in turn connectable via a latching connection with the supporting beam to be relocated. By rotating the intermediate member a height adjustment of the support beam is achieved with respect to the bottom part, whereby in other words the intermediate member acts as a spacer means (ie a means for setting a desired distance) between the support beam and the bottom part.

Furthermore, from the DE 20 2016 103 694 U1 discloses a comparable substructure with a support device in the form of a pedestal bearing. The pedestal bearing shown here also comprises a manually operable intermediate member (or intermediate part), which engages in an upper intermediate part connected to a support part and a lower bottom part. The support part connected to the upper intermediate part is connectable to a support beam via a screw connection.

The substructure comprises a large number of pedestal bearings as shown in the documents DE 10 2013 109 845 A1 and DE 20 2016 103 694 U1 known corresponds to a relatively complicated and therefore relatively expensive construction.

Presentation of the invention

The object of the present invention is to provide a substructure for supporting an elevated walk-on area, which overcomes the disadvantages of the prior art and, in particular, represents a simple and cost-effective solution.

These objects are achieved by a supporting device with the features of claim 1.

According to the invention, the at least one intermediate member with the at least two support beams directly or directly connectable and the intermediate member relative to each one support beam adjustable to adjust the distance between the support beam and bottom part, i. for height adjustment of the support beam.

It has been found advantageous that a waiver of the additional support member for supporting the support beams is possible by the inventive substructure and thereby the substructure can be significantly simplified. In particular, it has been found that a direct fixation between the preferably designed as a spacer screw intermediate member and the support beam is possible.

For the purposes of the present invention can be understood as elevated, accessible surface constructions, for example, terraces, walkways, balcony areas or the like.

Further advantageous embodiments are specified in the dependent claims.

Preferably, the intermediate member is formed by a spacer screw, wherein a thread of the spacer screw can engage in a support beam and thereby the spacer screw with a support bar directly connectable and is adjustable relative to the supporting beam.
