Floor structure for a building, for example, a parking garage, comprising primary beams (12), secondary beams (16-20) suspended on the primary beams and a lost form of sheet metal placed on the secondary beams. A concrete slab is poured in place in the form, which is trapezoidal and corrugated so that the concrete beams (47) are formed in the lower flanges of the form. The primary beams are lowered into the primary beams so that the concrete beams (47) are located below the level of the upper flanges (53) of the primary beams. |
