Formwork frame

The invention relates to the formation of a rectangular or square floor or ceiling opening serving formwork frame of a height *, which is slightly larger than the thickness of the floor or the ceiling, so that, for example, stairs can end there.

Until now, metal or wooden frames have been used for this purpose, the sides of which are removed afterwards the frictional connection between them is canceled. It requires a lot of time to take these frames apart and difficult to move.

In addition, attempts are being made in modern buildings where ' both the walls and the ceilings are made of cast concrete, ■ to cut out large openings *, which are often enclosed between two walls,

to put a temporary ceiling on the frame of the shaft, about driving on with relatively heavy machinery to enable, whereby there should be no protrusion on the ceiling surface, the wall attachment parts for the. pouring the upper storey at the same time as the cover slab,

This can be done with the previously known wood or metal shuttering " gen cannot be achieved, so that it is an object of the invention ... is to meet these demands.

To solve this problem, it is proposed according to the invention that to form the frame from two pairs of parallel side parts, one of which has protrusions on the outside

the other side parts' are performed, which latter sloping

The frame is made up of two side parts 1 and 2 of fixed length and two side parts j5 and 4 of variable length. It may contain a central elongate member intended to reinforce it and which is of a construction similar to that of the side parts 3 i and 4 i. The side parts -J- and 4 consist of a kind of double-T steel profile 6, which is protected on the outside: · by a flat, welded sheet 7, which is inclined longitudinally in such a way that · it facilitates unlocking by • lifting it upwards will. Each steel profile 6 has at each of its ends an axial pipe section 8 which is suitable for receiving a rod 9, which. can be brought into operative connection with one of the side parts 1 and 2. The rod 9 can be slid into the corresponding tube 8. In order to prevent the rods from being displaced, blocking pins 11 are provided, which penetrate through corresponding openings provided in the rods 9 and in the pipe sections 8 as well as in the sheet metal 7. The end 12 of each pin 11 can thus have a projection on the outer surface of the sheet 7

form in order to achieve an anchoring in the concrete; around ; To facilitate the pulling out of the pins li, their ends 12 have a conical shape.

The side parts 1 and 2 do not have any inclined surfaces. .

In order to make use of this framework, one supports it, whereby the side parts 1 and 2 are brought to the maximum distance, i.e., the rods 9 are then fixed in the pipe section 8 by the locking pins 11.
