Abstract

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.

A deck structure for resisting horizontal shear loads, said structure including a concrete fill, said structure comprising in combination: a. a fluted deck, said fluted deck including impervious top and bottom flutes and webs alternately interconnecting said top and bottom flutes; and b. downwardly oriented loubers disposed within at least some of said webs for venting the concrete fill to insure complete curing of the concrete fill and for physically locking the cured concrete fill with said fluted deck, said louvers within each said web being horizontally spaced to preclude overlap therebetween along a vertical axis.
Claim 10
Dependent Claim 21 words
The structure as set forth in claim 7 wherein a plurality of said louvers are disposed in each of said webs.
Claim 11
Dependent Claim 33 words
The structure as set forth in claim 8 wherein each of said webs includes two rows of said louvers, said louvers in one row being horizontally separated from said louvers in another row.
Claim 12
Dependent Claim 32 words
The structure as set forth in claim 9 wherein the lower one of said rows of louvers are at least 1/2 of an inch above the adjacent one of said bottom flutes.
Claim 13
