Support frame for horizontal formwork

The invention relates to a support frame for horizontal formwork.

The previously known designs of support frames for horizontal formwork have several disadvantages. There are, for example, support frames of this type, which can be used to mount cladding of various dimensions can be. ' For this purpose, however, individual elements are used that are adapted to the respective dimensions, so that the combination of these elements is only suitable for certain dimensions of a formwork. A larger number of different elements must therefore be available.

The horizontal support plate of this essay 21 is once with four Bores 22 for attaching a railing, not shown, and for other provided with two bores 23, which in the same way as the Bores 18 of the fastening plate 16 are formed and are used to fasten the last profile element 3. Because of this movability the attachments 21 can easily cover the area of the support frame according to the invention be adapted to the respective size of the casing.

For cladding, for example, a ceiling with protruding beams a longitudinal beam as shown in FIG. 4 is used. Like the carrier 2, this carrier also has a certain length and consists of two tubular struts 24 and 25, which by means of vertical bars 26 and 27 are connected to each other. These vertical bars 26 and 27 are in this case, however, it is extended upwards over the upper longitudinal strut 24.

As on the strut 6 of the carrier 2, they are also seated on the strut 25 here Fastening plates 10, 11 and 17. The vertical bars 26 and 27 also wear fastening plates 8 and 9 at their upper ends. The stiffening of this The carrier takes place by means of further, vertical cross braces 28 and corner plates 29 and 30. Above the upper longitudinal strut 24, further corner plates 31 and 32 can also be provided, which are located on both sides of the extend upper mounting plate 33 with the bores 33a.

10983? / 0569

This mounting plate 33 on the upper longitudinal strut 24 serves like that Fastening plates 16 of the carrier 2 for supporting and fastening the profile elements 3.

In Figures 5 and 6, a device is shown as it is for holding vertical formwork panels are used when a ceiling in the same Height should be shuttered with the upper edge of a wall. Here, a clamp 34 can be displaced by a few centimeters between the profile elements 3 arranged so that the necessary game for stripping is given.

This bracket 34 sits in a guide 35 made of a carrier plate 36 and a tubular part 37. Two plates 38 and 39, which are provided with bores 40 and 41, are welded to this tubular part 37 are. By means of these bores 40 and 41, the carrier part 36 can be fastened to the outer end of a hollow profile element 3.

A bolt 42 is displaceable in the longitudinal direction within the guide 37, which is provided at its inner end with transverse bores 43 for receiving locking pins to prevent falling out. At the Provided at the outer end of this bolt 42 is a carrier plate 44 on which the aforementioned clamp 34 is screwed or riveted.
