Device for pouring concrete slabs

The invention relates to a device for pouring concrete slabs by means of a trimmed casing

Such a supported formwork consists of each between two supports supported longitudinal beams over their entire length to form the concrete slabs serving mold surfaces, and several beam support elements that are independent of each other adjustable on parts of the longitudinal beam and over the length of the same are arranged distributed. The beam support elements can be locked in their operational position, in the Formwork boards worn from the inside have such a position that their surfaces serving as shaped surfaces are in a plane with the Form surfaces of the longitudinal beams lie. The locks can be released individually so that the beam support elements In lower a position in which the shuttering boards can no longer be supported and can therefore be removed. The shape of the The longitudinal beams remain in contact with the concrete slabs.

The present invention goes along with an apparatus several such longitudinal beams, which are supported by supports and between which cross beams run, the ends of the beam support elements are carried and the shuttering boards wear, which form surfaces lying in one plane with the shaped surfaces of the longitudinal beams.

The invention has the object of further such a device to improve; at the same time, the device should be designed in such a way that the transverse beams are optionally attached to the longitudinal beams can be that you either change the height of the shaped surfaces formed by the shuttering boards or auoh

Can use shuttering boards of different thicknesses. It is also part of the object of the invention to address the difficulties and disadvantages of the prior art to avoid.

One proposed by the invention to solve this problem Device is characterized by several longitudinal beams that Have a shaped surface over its entire length for shaping the underside of the concrete slabs, through several shuttering boards, their Top has a molding surface for shaping the underside of the concrete slabs, by several, over the length of the longitudinal beams distributed and adjustable on these independently of one another fastened beam support elements, by transverse beams running between the longitudinal beams, the ends of which are attached to the beam support elements are attached and which carry the shuttering boards, by supports for supporting the longitudinal beams which can be fastened to these and by means of locks to fix the Balkentrageleraente in a working position in which the shaped surfaces of the shuttering boards and the longitudinal beam lie in one plane, with the locking mechanisms the beam support elements are detachable and these can be lowered into such a position that the shuttering boards carried by you from the underside of the concrete slabs can be removed while the shaped surfaces of the longitudinal beams are in contact with the concrete slabs stay.

Further advantageous embodiments of the invention and those with The advantages that can be achieved by the invention emerge from the following description of an exemplary embodiment, which is based on a drawing is explained in more detail; show in detail:

Flg. 1 is a perspective view of a device for pouring concrete slabs according to the invention;

FIG. 2 is a plan view of one in the device according to FIG Figure 1 used crossbeams;

Fig. 5 is a view of the end face of the crossbeam.

009847/087

The device shown in FIG. 1 has longitudinal beams 10 with head pieces 11 which support the longitudinal beams 10 on supports 12. For supporting crossbars 15, as shown in FIGS. 2 and "3 are shown, serve beam support elements 13. Each crossbeam 15 consists of a long beam made of sectional steel, which is so-formed is that it encloses a wooden beam 16. At the ends of this channel-shaped profile support sits a U-shaped Bracket 17, the legs of which are attached to the sides of the profile beam. The supporting center piece of every bracket is provided with a shallow incision 17a on one side and a deeper incision 17b on the other side. A U-shaped additional bracket 19 is each attached to one of the two brackets 17 of a crossbar 15, the supporting middle part of the additional bracket 19 is provided with incisions which correspond to the incisions 17a and 17b. To a Longitudinal bar 10 each has a cover profile 20, the upward-facing middle part of which forms a shaped surface.

When the beam support elements 13 are locked in their ready-to-use position and the brackets 17 with their fleeing incisions 17a rest on this, the open side of the U-shaped profile support forming the crossbeam 15 shows upwards, see above that its bent edge surfaces can carry a plywood shaped plate, the top of which with the shaped surfaces of the longitudinal beams 10 and the head piece 11 completes. When the crossbars 15 are turned over so that their deeper cuts 17b on the beam support elements 13 rest, the middle pieces of the crossbeams 15 forming profile beams upwards, so that they can carry flanged, elongated shuttering boards, the longitudinal axis of which is then parallel to the longitudinal axis of the Longitudinal bar 10 runs.

The additional brackets 19 attached to the crossbar 15 grip under a bent-down edge of the cover profile 20, which on

the longitudinal beam 10 rests. The head pieces H of the supports 12 are also provided with hooks 21 in which the bracket 17 with their notches 17a or 17b can be hung. If a transverse beam 15 is to be hung behind the ends of the longitudinal beam 10. .
