ABSTRACT:
A fluted deck for use in the building industry includes a plurality of vents disposed within the webs interconnecting top and bottom flutes. Since the webs are proportionally stronger than the top and bottom flutes, the vents do not reduce the inherent strength of the deck. The vents are inwardly oriented louvers longitudinally aligned with the troughs developed in the deck. When concrete fill is poured upon the deck and particularly when the concrete fill is covered by non-porous insulating material, the vents promote and insure more uniform and more complete curing than unvented deck. The inwardly directed louvers form recesses or depressions within the concrete fill to physically interlock the deck with the concrete fill and form a high strength unitary diaphragm for buildings.
