Problems solved by technology

This method improves the load-bearing capacity of the support to a certain extent when vibrational stress occurs in the lateral or oblique direction, but it usually cannot effectively prevent the damage of the formwork support during the activities of ordinary construction sites.

Embodiment Construction

[0033] Preferred embodiments of the formwork support according to the present invention will now be described in detail with reference to the accompanying drawings.

[0034] figure 1 and figure 2A first embodiment of the formwork support 1 according to the invention is shown schematically. The formwork support 1 comprises an upper chord 2, a lower chord 4 and a web 6 connecting said chords, all of which are substantially made of wood. The web 6 may be a solid wall web, or eg a truss or lattice structure or the like. In this embodiment, the chords 2, 4 each comprise a recess 8 in the end region 1' of the support 1, which extends from the end face 1" of the formwork support 1 into the chords 2, 4. Furthermore, in this embodiment Among the examples, the recesses 8 are all set to be arranged adjacent to the web 6, that is, the recesses are adjacent to the web. But, according to the present invention, the recesses 8 can also extend into the web 6 or be arranged in the web 6, an...

Abstract

The aim of the invention is to improve the load-bearing capacity of formwork supports during shock-type stress that is effective especially perpendicular to or at an angle from the longitudinal axis of the support. The formwork support is made essentially of wood and is provided with a top chord, a bottom chord, and a web that connects the two chords. The web and / or at least one of the chords comprises at least one recess in at least one final area of the support, said recess being filled with a filling material that has shock-absorbing properties. The invention also relates to a method for producing such a formwork support.

Description

technical field [0001] The invention relates to a formwork support comprising an upper chord (upper chord), a lower chord (lower chord) and webs connecting said chords, all of which are substantially made of wood, and a method of manufacturing such Method of Formwork Support. Background technique [0002] Formwork supports of the above-mentioned type are widely used in construction work. Formwork supports used on construction sites are subjected to high mechanical loads, in particular vibrational and impact stresses, for example, when the support is dropped from scaffolding or the like. There is therefore the risk that the formwork support is damaged so that it no longer has sufficient dimensional stability or even load-bearing capacity. [0003] In order to solve this problem, various protective constructions for formwork supports are known in the prior art, wherein the ends of the supports are usually provided with covers or the like. For example, DE 43 04 438 A1 disclo...
