A ceiling formwork 18 of the respective ceiling field 11 to be produced is by means of adjustable formwork column reinforcement bars 27 but run into support 21 on the floor slab below through the next floor. The ceiling tile is over 22 supported, the formwork supports 21 on foot 5 longitudinal beams 28 stretched across, which in turn their carriers 23 are available, which serve to distribute the load. Transfer loads to crossbeams 29, which are provided with lugs 30

To the ceiling formwork 18, for example, from the one on the supports 16 with the interposition of To be able to move field lic into field 12c, sliding plates 26 are on top.

On this roller 10 concreting on short traverses31 , the ceiling formwork is pushed through the block 23 α after the openings in the supports 16, hardening of the respective ceiling field is drained and the traverses 31 carry rolled profile girders 32, which are used as on the floor slab below 22 are used in the sliding track for the slab formwork 18, continue to the next slab field. The formwork parts 24 that are to be moved downwards after they have been lowered into the next supports 16 are to be moved down 15 ceiling field,

j During the construction of the building, a reasonably even temperature gradient is initially required

the structural supports 16 erected and expediently arises from the joint to the already completed ceiling parts with the floor slab underneath to the rear. It is not connected to this. The structural supports 16 can be manoeuvrable in their 30 so that the mobility of the ceiling fields correspond to the height of a storey height, but their hardening is retained for a long time,
It is also possible to run them over several floors. After sufficient hardening, the

18 with the help of the formwork props 21, which can be lowered simultaneously or successively as hydraulic fields and designed telescopic presses, in 35 in the next three ceiling fields 12 a, 12 b, 12 c on a ceiling field, for example the ceiling field 11, the sliding tracks 32 drove up and brought it back into position and brought it exactly out into position at its height. The concreting process and that aligns. Then the prefabricated reinforcement for steam treatment then begins again, as the ceiling field 11 is placed in the formwork and this is described above.

Ceiling field concreted in place, with 40 as soon as at least three ceiling fields 11, 12 and 13 placed one on top of the other in the working direction behind in the area of the consoles 17 are finished. After concreting is placed under and over and their steam treatment is completed, the floor ceiling 11 can be attached to the ceiling panels 11 and 12 of the steam hood and the ceiling concrete in rows a, b and c delimited spaces 33 over the known Way hardened by steam. The central supports 45 and, of course, changes in length of the plate connected to the edge of the supports can be filled with concrete, since then none of them are not transferred to the supports 16, since the plate value changes in length of the ceiling plates 11 and, thanks to the sliding plates 26, occur on the brackets 17 in 12 and constraints can no longer move unhindered to the horizontal direction. are feared. If necessary, you can order completely

As soon as the ceiling field 11 is sufficiently firm, the ceiling fields 14 also first has achieved speed, the formwork parts 24 are concreted and treated with steam before one with see the supports folded down, the ceiling - concreting the openings above the supports formwork 18 is lowered onto the roller blocks 23 α begins. Sometimes it is also useful, all of them first and to complete in their entirety in the next ceiling field 12 ceiling fields of a floor before the moved on, where the same process was repeated anew starts. eliminated and these are connected to the supports.

After completion of a support 16 in the same way is then with the rest

The slab formwork will then Concrete top edge of the ceiling. If the supports from 60 after making the supports 16 for the next In-situ concrete, this can be done together with the loading upper floor by a hoist or toning the support of the next floor is done on the floor slab that has just been completed. The connection of the ceiling panels with the lifted, so that now with the manufacture of the next Support is started by short, cross-shaped floor slabs, whereby Tendons 34 produced. 65 now appropriately reverses the working direction and

Claims (4)

1 2 floor ceilings of a building to reduce and patent claims: this reduces the construction time with little effort. 1. A method for producing one or more floors Buildings whose ceilings are made of steel 5 solves that the concrete ceiling field on the or prestressed concrete by means of a grid-like column-prop in the horizontal direction initially shifting arrangement superimposed in one or more rows of borrowed, for quick hardening of one above the other Subject to surface vaporization of approximately the same size ceiling fields and subdivided after completion in which the ceiling panels are firmly connected to the supports to reduce vaporization at least one row of ceiling panels after production becomes io. the supports assigned to them on a lowering such a method allows in advantageous steam hardening even with in-situ concrete from formwork Concreted on the spot successively guided structures, as the ceiling panels during are, characterized in that the setting and hardening during the steam verdas each concreted ceiling field (11) on which 15 are slidably supported and only after being supported (16) in the horizontal direction, they initially sound displaceable as a result of the steam treatment superimposed, length changes called for rapid hardening are firmly connected to the supports Surface vapor deposition are subjected and bound. Through these measures will be outside Termination of the vaporization with the studs has the advantage that even with in-situ concrete zen (16) is firmly connected. 20 structures produced a much faster 2. The method according to claim 1, characterized in construction progress and a higher concrete strength, that the individual ceiling fields (11, half a short time is achieved. 12, 13, 14, 15) on protruding from the supports Consoles (17) are supported. Supports cantilevered consoles are supported. 3. The method according to claim 1, characterized in that it is also possible to initially only use the supports indicates that the supports (16) initially only approximately up to the lower edge of the supports they carry to be concreted roughly to the lower edge of the floor slab supported by them, then the after-one slab field (11) concreted, then the slab fields concreted one after the other with protruding other concreted ceiling fields (11, 12) to be placed on the supports with front lugs and after the spring Lugs (30) on the supports (16) harden the ceilings resting on the supports and after the hardening of the spaces delimited by these on the support plates via the zen (16) overlying ceiling fields (11, 12) to fill the columns with concrete. The latter construction has of these limited spaces (33) over the stud advantage that the ceiling tiles than between two zen (16) are concreted. Beams can be designed with transversely tensioned plates 4. The method according to any one of claims 1 to 3, 35 can, wherein only the beams on the supports characterized in that they all rest in the transverse direction. of the building next to each other ceilings- In order to avoid constraints that can arise with the steam fields (11a, 11b, lic) concreting and hardening at the same time, it is advisable to steam all of them in. Transverse direction of the building adjacent to each other 40 ceiling fields to be concreted and steamed at the same time.

The hardening time of the concrete is 60 rows a, b and c of the same size more square due to the heating during setting but not ceiling fields 11. 12, 13, 14 and 15 is divided. This shortens and does not improve the strength of the concrete.
