ABSTRACT:
Cellular steel flooring is provided which includes corrugated steel decking and separately applied cover plates which establish a lengthwise cell in cooperation with a valley and the two connecting sloping sidewalls. The resulting cellular steel decking permits distribution of electrical wiring or ventilation air throughout a building without requiring perforations or penetrations of the crest surfaces or sloping sidewall surfaces of the decking. The resulting wet strength of the cellular steel decking remains undiminished. The exposed corrugated undersurface of the corrugated steel decking provides an improved adhesion surface for subsequently applied fireproofing materials. Special cover plates for noncellular troughs are provided along the locus of transverse electrical trench structures to facilitate the mounting of the electrical trench and to permit strengthening concrete to be applied beneath the electrical trench.
