Floor comprising girders and structural floor units as well as a seamless cast slab on these girders and structural floor units

摘要

The floor has shuttering structural floor units (42) interposed between concrete girders (19). A seamless cast compression slab is arranged on the girders and the structural floor units. Each girder has a flat upper surface (23), and flanks (24, 26) partially encased by wedges of the slab. The flanks have main surfaces (27, 36) that are parallel to each other. The flanks are provided with longitudinal key forming ribs (28, 37) projected from the main surfaces. The longitudinal ribs are encased by the wedges and the slab.
