SUPPORT MADE FROM STONE AND TENSION-RESISTANT MATERIAL

Abstract

The invention describes a girder profile made of stone material and tensile-resistant material, which is preferably made of 002 in order to fix greenhouse gases. This is intended to replace steel girders and aluminum girders with sustainable building materials.

The invention adopts the principle of dovetailing from timber construction and transfers this principle to the structure made of stone material and fiber material, in that the planes of the profile, which usually meet orthogonally, overlap geometrically with regard to the tension-stable material parts or at least meet in one cutting plane.

Such materials made of mineral substances and fibrous materials are significantly lighter, more durable and more ecological than such carriers made of metallic materials.

Claims

7. Arrangement according to claim 6, characterized in that the fibers are glass, stone, carbon, aramid, bamboo, wood or flax fibers or a mixture of these fibers.

11. Arrangement according to claim 1, characterized in that the raw materials for the carbon fibers, the resins and adhesives come from plant residues that remain in papermaking, for example in the form of lignin and other plant residues, which are delivering fermented yeast oils, with help of yeast, for the biogenic production of PAN-based carbon fibers, graphene, resins and binders.

12. Arrangement according to claim 1, characterized in that PAN-based carbon fibers and/or resins and binders are produced from CO2 using synthetic processes.

Description

[0022] One of the many possible versions of the invention describes in FIG. 1 and FIG. 2 a CFS plate (1) as the upper chord and a second underlying stabilizing CFS plate (2) as the lower chord, each with an internal carbon layer (4) in the plates, with a web (3) arranged vertically to the plates (1) and (2) which is made of CFS, having also an internal carbon layer, which stiffens the overall arrangement. FIG. 1) shows the dovetailing and cutouts (5) of all panels which allow the panels to have interlocking structures which ensure cross-panel adhesion when the panels are interlocked with adhesives. The optimization of the components is achieved by the upper chord getting more stone contingent than the lower chord and the lower chord more carbon contingent than the upper chord. In the same way the carbon footprint can be optimized.

[0023] FIGS. 3 and 4 show the structure of FIG. 2 in cross section (F-F) and (G-G), with which the two plates (1) and (2) are mechanically force fitting connected with the help of dovetails via the CFS plate (3).

[0024] The same is shown for a T-beam in FIGS. 5 to 8 as an example. The two designs are representative of the principle of connecting the CFS panels with the help of dovetailing of the edges to be glued together in order to also connect all possible other structures at right angles or at an angle and force-fitting by the fact that the carbon surfaces with high tensile strength viewed from the perspective of the cross section are in intersect or at least meet at a cutting line.
