ABSTRACT:
A composite slab useful as a floor or roof structure of a building. The composite slab comprises plural cellular sections which span across horizontal structural support beams, and which provide a substantially flat upper surface and plural longitudinal cells disposed below the flat upper surface. Certain and preferably all of the longitudinal cells are substantially entirely filled with concrete. Plural spaced portions disposed along each of the cells interrupts the interior surface of the cells, whereby the concrete is extended out of its normal plane in the region of the spaced portions and achieves a positive mechanical combination with the cellular section. The resulting composite slab develops predictable and reliable composite coaction between the concrete and the metal cellular sections throughout the lifetime of the building.
