for a formwork system ^ »

The disher with SclialuBgspasseeles κηδ / or carriers Formwork systems have sicn. in practice only for peeling of walls and columns proven to be economical and come to the The shuttering of a concrete ceiling is out of the question, as the use of an adjustable nozzle formed by it worn formwork base due to the long hardening time of the concrete slab, which usually had a formwork time of 28 Days is not very economical in terms of the costs required for the formwork system is.

The! Innovation intends to avoid this disadvantage and to create a prop head that supports the susan with the other

closing formwork panels form the formwork surface for the Can form ceiling, the formwork panels and the formwork beams can be removed independently of the top plates before the concrete slab has finally hardened. In this Way, the ceiling can be fully supported by the head plates remain until complete hardening is achieved without this after a previous removal of the formwork panels, e.g. by supporting unwanted deformations, tensions, and is exposed to vibrations, which affect the strength of the Se = affect tons. The other formwork parts are released for further use after a short time.

According to the inflation, this purpose is achieved in that the Support head has an upward guide shaft on which Upper side a formwork panel is attached and on which entlaag a lockable formwork support part rotatably displaceable is provided with a stop serving as a spacer.

With this stop, the support part can home shuttering in the correct Distance in relation to the top of the fixed upper plate are clamped and when Eutschalen over a sufficient Distance decrease so that removal of the formwork parts is possible borrowed. Due to the fact that the support parts can be rotated on the Guide shaft, the cross-section of which is e.g. triangular, flat-oval or rounded with special gate elevations to prevent rotation of the supporting part guided thereon, the L * g · des lies

Stü'czteiles and thus the attachment point for the actual Formwork parts, e.g. formwork beams or formwork pairs neele, stuck in the horizontal plane. By getting the top plate • lets form a part of the casing bottom, also lies the Height of the support part, after setting the support height, in vertical Sense firmly. After the concrete slab or beam has hardened sufficiently, the formwork parts can be removed and the concrete ceiling remains so long through the obscure slab supported until the concrete has finally hardened and also the StÜta can be fetched away with prop head. It is only through this innovation that it is possible to make the formwork system economical for both to use vertical as well as horizontal concrete structures, the formwork system with the help of relatively unskilled personnel can be built.

If you have the support part with a right-angled opening around the can-shaped guide shaft with right-angled Cross-section lets you see what breakthrough you are about The upper part of the collar extends over the upper part of the shaft which is brought to a stop against the top plate verdeij & ami, is a strong guide shaft and a collar that is easy to make from welded-on strips to support the leads around the shaft without clamping and can serve as a stop.

According to the hiring, the upper stop for the support part can be used by two strips welded on both sides of the guide shaft are formed. This will make it possible to place the top plate on top an easy way to weld it to the outside of the guide shaft.

Conveniently, the stirrer shaft is used to attach the Support part with sei-Qichen projections and with a means of a Locking element guided along the shaft, that with the support part by means of corresponding recesses arranged for this purpose vertically past these projections and can be locked horizontally. This horizontal locking movement makes a further passage of the projections not possible*

Among other things, to keep the wear and tear when clamping as low as possible, can the side projections by a rotatably mounted in the shaft ^ through pin or the like. be formed on what the locking element can be wedged tight by means of inclined rope surfaces.

The locking element can be provided with a lug protruding outside the support part in the wedged state. This makes it easier to wedge the locking element aehx .

A very simple installation and dismantling of the formwork parts can be achieved, for example , in that the support part is guided out in the form of a plate and provided with hooking ears on which formwork supports or formwork panels can be hooked.

According to the innovation, the breakthrough in locking can be gselera & Tnt be designed such that a rotation of the locking element is made possible by 90 ° around the guide shaft, whereby because «working near walls or such obstacles is made much easier.

The support head also has a plate-shaped support part 10 which can be displaced along the guide shaft and to which Formwork beams 30 are suspended ,, These formwork beams are indicated by dash-dotted lines. The support part 10 engages with a reefcwiJikXigen opening 11 around the guide shaft 5 » Two ears 33 protrude upward from the support part, onto which the formwork supports 30 are hooked.

For a jam-free guidance along the guide shaft, the support parts 10 are provided with an upwardly directed collar 13. Since this collar can come into contact with a strip-shaped upper stop 14 on the guide shaft 5, the level of the hooked formwork supports is also fixed upwards Serve stop

To concrete a ceiling 32 (see Pig. 1) the Supports 2 may be set upright by means of temporary horizontal connections and the formwork supports 30 on the support parts 10 hooked. The support parts are supported by the Driving the wedge pieces 20 pressed against their stops 14, making them autoaatiscji the correct height with respect to the

upper side of the upper plates 6 received. The supports have been then adjusted to the correct length and on the formwork beams 30, the formwork panels 31 are placed, all around

After the "concreted floor" some time, e.g. some Days, is hardened, can be proceeded to partial removal of the formwork. For this purpose, the wedge 20 is released, which jj can easily take place because its tail piece 24 protrudes outside the support part 10, whereby the support part with the formwork girders something will go down. This will not be enough to remove the formwork beams with formwork panels from the support parts to be able to, so that a sinking of the support part and the wedge piece under the pin 7 is necessary. To this end are the slots 11 and 21 in the support part and the wedge piece are provided with lateral recesses 12 and 22, respectively, which form a passage enable via the pin 7. The recesses 22 are therefore at the end of the wedge surfaces 23. The collar 13 is also interrupted at the point of passage for the pin 7 and shows a vertical slot 15 there (see Pig. 4).

The formwork girders with the formwork panels lying on them can now sink down to the lower panel 1 of the column head, after which the formwork panel *! removed and the formwork beams are unhooked. These parts can then be used again at a different location. The concrete ceiling 32, which is not yet self-supporting, remains supported for some time by the supports 2 with the upper plates 6 lying against the underside of the concrete ceiling. The whole process can be carried out by relatively unskilled workers.

The open slot 21 with the recesses 22 in the wedge piece 20 (? Fig. 5) also have the advantage that the wedge piece, if the conditions make it necessary, by 90 ° can be introduced twisted.

If the formwork beams can be omitted, can the formwork panels also directly axd * the supporting parts 10 be attached. Furthermore, the innovation-like support head Form a whole with a support instead of being mounted on it to become"
