Embodiment Construction

[0020] exist Figures 1 to 3 A channel cover is shown in , which is made of ductile iron. The channel cover comprises a load-bearing structure 20 consisting of eight radially extending supports 21 extending inwardly from the outer edge of the cover 10 by an amount less than radius. The height of the carrier 21 (as this especially from figure 2 ) rise inwards from the outer edge and are connected to one another at their inner ends by eight carriers 22 arranged in a regular octagon. Thus, when the (inserted) cover part 10 is loaded vertically from above, the inner support part 22 is essentially subjected to a purely tensile load, which is drawn from the support part 21, more precisely From its underside (in the installed state) it is transferred to the lower carrier side 24 of the carrier 22 .

[0021] Relatively minimal tensile loads act on the carrier 22 in regions A, A', which are adjacent to the "coupling region" to which the ends of the carrier 22 are coupled. In this...

Abstract

The invention relates to a load-bearing structure for the covering of buildings, such as shafts or water channels, which can be inserted into the ground, wherein the covering (10) has a driveable surface (11) and the load-bearing structure (20) Below the surface extends downwards into the building and has a beam-shaped carrier (21-23), so that the carrier side (24) below the carrier facing away from the surface (11) is subjected to pressure on the surface (11). subjected to tensile stress under load. The invention is also characterized in that, between the two regions (A, A') of minimum tensile stress, the thickness (D) of the carrier rises substantially symmetrically up to a maximum value and then falls again to form (at In the bottom view to the cover) spherical shape.

Description

technical field [0001] The invention relates to a load-bearing structure for a covering of a building that can be inserted into the ground, wherein the covering has a surface that can be driven over and the load-bearing structure extends below the surface down to the building In an object and with a beam-shaped carrier, the lower carrier side of the carrier facing away from the surface is subjected to tensile stress when the surface is loaded. Background technique [0002] Covering elements for buildings which can be inserted into the ground are known, for example, from EP 1 031 664 A1 or DE 10 2011 051 545 A1. This known object is a so-called manhole cover. At this point, however, it should also be mentioned that the invention also relates to support structures for rectangular coverings, for example coverings for floor drainage channels, whereby it follows that the covering can also have openings. [0003] Covers of this type are usually made of cast iron or also of plast...
