Device for clamping τοη Eandsclaalungen on steel mold floors _β

The innovation relates to a facility for clamping edge formwork on shaped steel floors.

"In known-.BaüM ..-" - types mostly U-profiles are used as edge formwork, which are connected to the steel mold base by screws at the desired points The threaded holes that are not currently required ^: have to be plugged in. This is tedious and, if not carried out very precisely, can lead to unclean surfaces on the finished part.

The purpose of inflation is to avoid this disadvantage and create any formwork with little effort: to be able to.

The facility according to the innovation is marked; -.- '. through tensioning beams, which at one end have a vertical ^{pin that engages in edge formwork, in which a tensioning screw that can be tensioned against a flange of the edge - '"-:} formwork is guided and the other end is a row at a distance from each other in the longitudinal direction of the clamping beam aligned holes, and by a bracket connectable to the steel mold bottom via a Gr and plate with two parallel perpendicular cheeks, between which the clamping bar ⁷ engages and through one through first holes in the cheeks and _r one of the holes in your clamping bar entering locking pin is fixed in its longitudinal direction and is overlapped without play by a locking pin entering the edge through second holes in the cheeks.

In this way, the edge formwork is held down at the desired location by the tensioning beams, which are supported on the steel mold base via the brackets attached to the edge with this. It is therefore only necessary to provide a limited number of threaded holes in the area of the edge of the steel mold base. The measures provided for in the tie beam rows of holes allow the adaptation \ to ^~>: - "/ .the geweiligen circumstances These may conveniently v _~: v be to keep available clamping beams of different overall length!

In a further embodiment of the furnace is'. ^: provided that third holes in the cheeks of the trestle; are provided for receiving a locking pin, which zn the second holes parallel to the base plate of the block '\; have the same distance as the second holes from the first holes perpendicular to the base plate. As a result, the trestles can be attached to the vertical palms of the hands instead of their base plate on the horizontal surface of the steel mold bottom are * "'■ It is also provided that fourth holes for receiving a hinge pin are provided in the cheeks of the bracket, the centers of which form a rectangle with the centers of the first and second holes, and on the hinge pin a locking plate that matches the profile of the edge formwork sits. This allows the. Bock can be used as a joint to swivel the prefabricated part into the vertical position when it is formed on a tiltable steel mold floor, so that it can be lifted up vertically by a crane.

As Mg. 1 shows, a steel mold bottom 1 is

provided, which rests on a frame 2 made of U-iron. on the steel mold bottom 1 Rands ^ formwork 3 are placed, the are also designed as U-irons. The steel mold bottom 1 "_ and the edge formwork 3 form the shape for a prefabricated part concrete.

Each clamping bar 5 has at one end a perpendicular locking pin 6 in which a clamping *. "/ ■". screw 7 runs (Fig. 3). The clamping screw 7 is tensioned against the lower flange of the edge formwork 3, which carries an angle 8 through which the catch pin 6 passes with play. On the other side, each clamping beam 5 has one in its; Longitudinal row of spaced holes 9. In practice, clamping bars 5 of different lengths, for example three lengths, are used ^: depending on the prefabricated part 4 to be produced over the: --.-. To keep the edge of the steel mold bottom 1 protruding end as low as possible. The holes 9 are used to fix the clamping beam 5 on the steel mold bottom 1. \

For this purpose, a bracket for each clamping beam is attached to the edge of the steel mold base 1. Each book has a base plate 10 with fastening holes 11 and two spaced apart perpendicular cheeks 12, between which the clamping beam 5 fits. The base plate has between __- the cheeks 12 at one end of a section 13. In ^the:; Cheeks 12 are aligned first holes 14 are provided which; with inserted clamping beam 5 with one of the holes 9 to the _r ; Coverage can be brought. A locking pin 15 fitted with a toggle fixes the clamping beam in its longitudinal direction and thus determines the position of the edge formwork 3 ^.:

The cheeks 12 are also in alignment

second holes 16 through which a toggle provided Locking pin .17 is inserted, which engages over the tension bars 5 without play. The first and second holes are longitudinal of the clamping beam 5 distance "from each other. In the working position you see forces directed downwards on the clamping tube 7 and on the locking pin 15 and an upward force on the locking pin 17 »

In the embodiment according to lig. 1

the individual blocks are perpendicular to the edges of the steel mold bottom 1 with the base plate 10 supported on this. However, the blocks can according to FIG. 2 also secured to the vertical edge surfaces of the Stahlformboiens 1 ■ ".-. ■ be. The Ό iron of the frame 2 will then support plates 18, on which the base plate 10 is fixed so 'that the second Holes 16 can cooperate with the holes 9 of the clamping beam 5 inserted between the cheeks 12 in order to fix the latter in the longitudinal direction.

The cheeks 12 of the trestle contain

also aligned third holes 19 'through which a locking pin 20 is inserted over the clamping beam 5 without play in order to support the clamping beam. The second and third holes have the same distance in the direction lying parallel to the base plate 10 as the ^: first and second holes in the direction perpendicular to the base plate.

With this arrangement, the edge formwork 5 / when using short tension bars 5 close to the edge of the; Steel mold bottom are arranged. With enclosures between the support plates 18 and the base plates 10 of the brackets istν even one that goes beyond the division of the holes 9 Fine adjustment possible.

The fixing of the bracket shown in FIG _e 2 may also serve to form a joint (]? Ig.5). For this purpose, the cheeks 12 have aligned fourth holes 21, the center points of which form a rectangle ″ along those of the first and second holes 14 ″ and 16 ″. The holes 21 receive a hinge pin 22 on which a locking plate 23, which matches the U-shaped iron of the edge formwork 5, is seated. As FIG. 6 shows, the molded steel base 1 with its frame 2 can be tilted by a certain angle in order to lift off the prefabricated part 4. The remaining angle (A ^ to the vertical / position of the prefabricated part 4 is made by pivoting around the hinge pin 22, so that the prefabricated part 4 can be lifted vertically by means of a crane rope 24.

The innovation only requires a limited λ Λ Number of threaded holes on the edges of the otherwise smooth " Stahlformbodens 1 and allows arbitrarily arranged "edge formwork in a simple and two-way manner on the ■; Define steel mold bottom 1 * The required parts are to be determined the clamping device simple in structure and therefore cheap and under the relatively rough operating conditions. reliable.
