HORIZONTAL FLOOR MADE UP OF A LOAD-BEARING STRUCTURE AND FLOOR PANELS LAID THEREON

Abstract

A horizontal floor consists of a load-bearing structure and panels, which are laid thereon and together form a floor surface. The load-bearing structure is made up of at least one main profile, which is fastened on vertical supports, and secondary profiles, which are arranged transversely in relation to the main profile, are connected at their end to the main profile and on which the panels rest by way of their underside. Forces acting horizontally on the floor are absorbed by the load-bearing structure. For this purpose, a single piece connecting element is provided. The connecting element has a first fastening edge, a parallel second fastening edge, and a central portion between the two fastening edges. The first fastening edge is supported on the main profile and connected to it. The second fastening edge is supported on the underside of one of the panels and connected to this panel.

DETAILED DESCRIPTION

[0028] FIG. 1 shows a perspective view of a portion of a horizontal floor used in the storage and logistics area, consisting of a load-bearing structure and panels 7 laid thereon and together forming a flat floor surface.

[0029] The load-bearing structure is made up of the vertical supports, not illustrated, main profiles 1 fastened thereto and secondary profiles 2 arranged transversely in relation to the main profiles 1 and fastened laterally to the main profiles. All the main profiles 1 and secondary profiles 2 extend horizontally.

[0030] In the interspace between each two secondary profiles 2, a connecting element 20 is additionally fastened to the main profile 1. The secondary profiles 2 and the connecting element 20 each form with their upper sides a support for the underside 7A of the panel 7 or the panels 7.

[0031] The ends of the secondary profiles 2 are not connected to the main profile 1 directly but via a respective connection element 3. For this purpose, the connection element 3 is fastened to the secondary profile 2 by a connecting region 4A and to the main profile 2 by a connection flange 4B at right angles to the connection region 4A. To attach the secondary profile 2 to the connecting region 4A of the connection element 3, it is also conceivable for both components to have a complementary contour in order to produce a form-fitting and force-fitting connection when plugged into each other. In principle, a screw connection or riveting or a combination of screw connection and riveting and a form fit between connection element 3 and secondary profile 2 is also possible.

[0032] The connecting element 20 is advantageous with regard to the transmission of shear loadings, namely horizontal forces acting transversely in relation to the longitudinal extent of the secondary profiles 2, to the load-bearing structure. Their influence is primarily disadvantageous in the region of the connection of the secondary profiles 2 to the main profile 1, here therefore in practical terms in the region of the connection elements 3. Disadvantageous loading states can occur in particular when heavy goods are pushed onto the panels 7 screwed to the secondary profiles 2. This is because the secondary profiles 2 are better able to accommodate horizontal forces in the direction of their own longitudinal extent than horizontal forces transverse to their own longitudinal extent.

[0033] The individual connecting element 20 is made up of a first fastening edge 21, a second fastening edge 22 parallel to the first fastening edge 21 and a central section 25 between the two fastening edges 21, 22. The first fastening edge 21 is at least indirectly supported on the vertical profile section of the main profile 1 and screw-connected to the latter, here with the interposition of the connection flange 4B. The first fastening edge 21, the connection flange 4B and the main profile 1 thus form a common connection region.

[0034] Although the connecting element 20 is connected to the main profile 1 and to at least one panel 7, it is not connected to the secondary profile 2. Consequently, a force acting on the panel 7 transversely relative to the longitudinal extent of the secondary profile 2 is transmitted via the connecting element 20 to the massively and stably configured main profile 1 and not primarily to the secondary profiles 2. This leads to the load on the secondary profiles 2 being relieved, above all in the region of the connection elements 3.

[0035] The fastening edge 22 of the connecting element 20 and the secondary profiles 2 reach higher than the upper side of the main profile, with the consequence of a vertical clearance 16 between the main profile 1 and the underside 7A of the panel 7 arranged above the main profile 1.

[0036] In order to be able to change the vertical clearance 16, the connection element 3 can be formed with a plurality of holes 6 arranged vertically one above another on the connection flange 4B. As a result of the many holes 6, the connection element 3 can be fastened to the vertical profile section of the main profile 1 in various vertical positions.

[0037] The connection between the first fastening edge 21 and the main profile 1 is preferably made by means of two screws 17 which are spaced apart considerably relative to each other in the longitudinal direction of the fastening edge 21, which engage in holes in the vertical profile section of the main profile 1 and the spacing of which is at least 50% and preferably at least 75% of the total length of the first fastening edge 21. It is conceivable that more than two screws 17 and associated holes are also arranged along the first fastening edge 21 and the main profile 1, and connect these to each other.

[0038] Of course, further secondary profiles 2 and connecting elements 20 can also be placed on the main profile 1 from the other side, that is to say from the left in FIG. 2, wherein the fastenings can be made on both sides via common screw fixings.

[0039] The second fastening edge 22 of the connecting element 20 is supported on the underside 7A of the panel 7 and connected to the panel 7 via rivets or screws 18. The panel 7 lies on the secondary profiles 2 and is fastened thereto by means of the screws 18 or rivets. In order to make it easier, for example, for a load to slide on the floor panels, recesses are provided on the upper side of the panels 7, into which the screws or rivet heads are completely countersunk.

[0040] The main profile 1 is, for example, a steel support produced in a hot-rolling process, more precisely a double-T support with two horizontal legs running one above another and parallel to one another, and a vertical profile section connecting these. To fasten the first fastening edge 21 to the vertical profile section, the central section 25 of the connecting element 20 is made up of two portions 27, 28 connected at a bending line 33 extending parallel to the two fastening edges 21, 22 (FIG. 2). These portions are a horizontal 27 and a vertical portion 28, wherein the portions 27, 28 preferably extend at right angles to each other at the bending line 33, and wherein each portion 27, 28 is preferably connected to the fastening edge 21, 22 at a respective further bending line 31, 32.

[0041] In particular, the fastening edges 21, 22 are arranged at right angles to the portions 27, 28 arranged adjacent thereto. This likewise step-like configuration of the connecting element 20 ensures good stiffening of the load-bearing structure. However, a non-right-angled configuration is also possible, or another number of steps.
