Abstract

A formwork support for supporting concrete formworks in the construction sector, comprising an upper flange and a lower flange, which are connected to one another via a hollow profile web such that they are at an invariant distance in relation to one another, wherein the hollow profile web is stiffened inside by framework struts.

First claim

The invention claimed is:

1. A formwork support for supporting concrete formworks in the construction sector, comprising an upper flange and a lower flange which are connected to one another via a hollow profile web so as to be at an invariant distance relative to one another, wherein the hollow profile web is stiffened on the inside thereof by framework struts,
wherein first framework struts of the framework struts form a strut framework having transverse posts which are arranged so to as extend orthogonally with respect to two lateral walls of the hollow profile web that are arranged opposite one another and second framework struts of the framework struts extend away from a node region of the framework struts in a diagonal direction.

2. The formwork support according to claim 1 , wherein the hollow profile web is designed in the form of a metal extruded profile or in the form of a plastics extrusion profile.

3. The formwork support according to claim 1 , wherein the upper and the lower flange of the formwork support each have a flange body which is designed as a separate component to the hollow profile web and which is detachably fastened to the hollow profile web.

4. The formwork support according to claim 3 , wherein the flange body is made at least in part of wood, a wood material, or a plastics material.

5. The formwork support according to claim 3 , wherein the flange body is supported on and/or fastened in each case to a laterally projecting profile extension of the hollow profile web in an axial direction with respect to the vertical axis of the formwork support.

6. The formwork support according to claim 3 , wherein the flange body is formed in multiple parts and has in each case a first and a second flange body segment which each rest laterally against the hollow profile web.

7. The formwork support according to claim 1 , wherein the hollow profile web extends over an entire overall height of the formwork support.

8. The formwork support according to claim 3 , wherein the flange body and the hollow profile web engage in one another in the direction of the vertical axis of the formwork support over the entire longitudinal extent of the hollow profile web.

9. The formwork support according to claim 1 , wherein the upper and the lower flange of the formwork support are integrally formed on the hollow profile web.

10. The formwork support according to claim 1 , wherein the hollow profile web has closed or substantially closed lateral walls or in that the hollow profile web has a plurality of through-recesses, such that the hollow profile web forms, in the direction of the longitudinal extent thereof, framework profiles which are integrally connected to one another.

11. The formwork support according to claim 10 , wherein the framework profiles are each arranged so as to extend obliquely with respect to the upper flange and to the lower flange at an acute angle β, where the angle β is preferably: β>45°.

12. The formwork support according to claim 1 , wherein the hollow profile web is completely foamed.

13. A formwork support for supporting concrete formworks in the construction sector, comprising an upper flange and a lower flange which are connected to one another via a hollow profile web so as to be at an invariant distance relative to one another, wherein the hollow profile web is stiffened on the inside thereof by framework struts, wherein the framework struts comprise a framework strut which is arranged to extend orthogonally with respect to two lateral walls of the hollow profile web that are arranged opposite one another and a further framework strut which extends away from a node region of the framework struts in a diagonal direction.
