Definitions
- the invention relates to a composite steel ceiling with ceiling beams and attacking precast panels.
- Such composite steel ceilings are in different Embodiments known. In many cases they exist Ceiling beams made of steel profiles with a T-section or double-T section. On the top straps or straps of the ceiling beams precast panels can be placed, for example Filigree slabs.
- the object of the invention is therefore a composite steel ceiling the genus mentioned in such a way that at simple assembly as simple as possible is made possible.
- the Ceiling beam steel-concrete composite beam with double-T cross-section are each a belt plate as a steel lower flange and have a web plate connected to it, the precast panels with support tongues on the belt plate are supported that the web plate at its upper edge forms a bond with a concrete top chord that In-situ concrete consists of recesses in the precast slabs is introduced above the support tongues, and that a upper chord reinforcement extending on both sides of the web plate of reinforcement ends of a plate reinforcement protruding into the recesses of the precast panels on both sides is overlapped.
- the material requirement for steel for the ceiling beams is relatively small, because only the lower flange and the web of the ceiling girder are made of steel.
- the top flange of the Ceiling girder consists of in-situ concrete with an inlaid Upper chord reinforcement, being a composite with the web plate will be produced.
- the manufacture of the composite steel ceiling is especially simplified by the fact that no formwork is required because of the in-situ concrete in the recesses of the precast panels are inserted on both sides. The the amount of in-situ concrete required is very small.
- the composite steel ceiling has a high load-bearing capacity because of the overlap of the upper chord reinforcement with both sides Reinforcement ends of the plate reinforcement in a very simple way a good flow effect is achieved.
- the upper chord reinforcement extending transversely to the longitudinal direction of the girder the split tensile forces of the pressure diagonals in the in-situ concrete top chord on.
- the ceiling girder is achieved a continuous effect through the upper chord reinforcement. The force is applied in the center of gravity of the concrete top chord.
- the dimensions of the steel lower flange are exclusive given by the static requirements and are sufficient for Supporting the support tongues of the precast panels in any case, so that the material requirements for steel are minimized becomes.
- the upper chord reinforcement can be made from simple prefabricated reinforcement mats exist.
- the force between the web plate and the subsequent one In-situ concrete is created by a composite effect at the top of the Web plate reached.
- a composite effect at the top of the Web plate reached is created by a composite effect at the top of the Web plate reached.
- Edge of the web plate recesses are formed so that a toothing between the web plate and the in-situ concrete Concrete upper chord is reached.
- Those recesses of the web plate are preferably those take up one reinforcement bar of the upper chord reinforcement, open to the upper edge of the web plate. This allows the top chord reinforcement can be inserted from above in a very simple manner.
- the composite steel ceiling shown in Fig. 1 has several Ceiling beams 1 arranged parallel to one another, wherein in Fig. 1 only a single ceiling beam 1 is shown. On both sides of the ceiling beam 1 is off Reinforced concrete existing precast slab 2 arranged.
- the ceiling beam 1 is a steel-concrete composite beam with Double-T cross-section. He has a belt plate as Steel lower flange 3, with a vertical web plate 4 connected, for example welded or as one piece Rolling profile is made.
- the prefabricated panels 2 have on their ceiling beams 1 facing edges each support tongues 5 on the Top of the belt plate forming the steel lower flange 3 are stored.
- each support tongue 5 is on the edge of each precast slab 2 each have a recess 6 or notch intended.
- Each precast plate 2 has one in the support tongues 5 protruding lower plate reinforcement 7 and an upper plate reinforcement 8, the reinforcement ends 9 in the recesses 6 protrude.
- the lower plate reinforcement 7 can also be prestressed Reinforcement.
- a top chord reinforcement consisting of a reinforcement mat 13 is inserted into the recesses 6 so that they are on both sides the reinforcement ends 9 of the plate reinforcement 8 overlap and some reinforcement bars of the upper chord reinforcement 13 through the open to the upper edge 12 of the web plate 4 Extend recesses 11.
- the space delimited by the recesses 6 on both sides of the Web plate 4 is with in-situ concrete up to the upper edge 15 of the Precast panels 2 backfilled.
- the in-situ concrete forms together with the upper chord reinforcement 13 one with the web plate 4 positively connected concrete top chord 14 of the ceiling beam 1.
