Abstract

The invention relates to a device for the continuous extension of straps, in particular formwork straps with top plates. The aim of the invention is to eliminate the disadvantages of the known formwork beams and to provide a possibility for the continuous extension of formwork beams. The invention has for its object to provide a component which allows the continuous Verlaengerung of straps, in particular shuttering carriers, which are frontally provided with top plates. According to the invention, the object is achieved by connecting a coupling element to the top plate of the formwork girder, above which a trough carrier with rows of holes is pushed in a small grid. Formwork carriers and trough carriers are connected by bolt-wedge connection. Fig. 1

Device for extension of carriers Field of application of the invention

The invention relates to a device for the continuous extension of carriers, in particular scaffold carriers π with Kojd plates.

Characterization of the known technical solutions

There are formwork supports known «can be extended frontally and have a flat belt surface for receiving the formwork skin.

The disadvantage of this formwork support is that «only formwork support can be connected with a certain length to the frontal head plates. The length adjustment is only possible by joining different length carrier shots in coarse grid jumps. Such formwork supports, for example, can not always be used as slab formwork beams between existing walls.

Object of the invention

The aim of the invention is to eliminate the disadvantages of the known formwork beams and to provide a possibility for the continuous extension of formwork beams. ..... ^! . - .; ^_: - * V. '. : ·: '. ',: · ..

Explanation of the essence of the invention

The invention has for its object to provide a component; which allows a continuous extension of carriers, in particular formwork carriers, which are provided with head plates on the front side, without weakening the webs of the formwork carriers by bores or the like. According to the invention the object is achieved in that on the top plate of the formwork support a coupling element is closed to ~, which is provided with one or more holes ·

As an extension element, a trough carrier is arranged. The trough support is designed so that it can be pushed over the coupling element on the formwork support frontally.

It is provided in the upper part of the webs and in the flange, each with a row of holes, which serves as a connection to the coupling element or to the perforated lower flange.

On the formwork beams web reinforcements are arranged directly at each end, having one or two holes for connecting the trough carrier to the formwork support. The trough carrier has instead of the rows of holes in the lower flange in the lower part of the webs rows of holes · Due to the special shape of the tray carrier, it can be pushed as far as desired on the formwork support and connected in a form-fitting according to the hole pattern.
