Abstract
Abstract A roof deck construction in which a plurality of spaced beams having wooden nailers on their upper surfaces receive elongated metal sheets parallel to the beams with the edges of the sheets being joined together along the nailers. The adjacent edges are joined by connectors and the connectors are in turn secured to the nailers by driving nails or equivalent fasteners through the connectors, between adjacent edges, to the nailer.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
118 words
A deck structure comprising, a plurality of longitudinally extending spaced parallel beams, elongated nailers secured for longitudinal sliding movement on top of said beams, a plurality of elongated, flat sheets of steel extending longitudinally between said beams, upwardly projecting L-shaped flanges at the longitudinal edges of said sheets, said flanges terminating in inwardly projecting horizontal legs, a plurality of longitudinally spaced clips straddling the edges of adjacent flanges and having portions extending downwardly and under the edges of said legs, a fastener projecting through each clip into said nailer, a watertight strip of felt overlying adjacent flanges, said strip being wrapped downwardly around said legs, and a longitudinally extending cap overlying said strip and clinched around said legs.
Claim 2
Dependent Claim
