A sheet metal decking unit useful in the construction of a composite floor. The sheet metal decking unit exhibits substantial wet strength (ability to support wet concrete between spaced supports); has long span capabilities; and is useful in single and multiple span applications. The sheet metal decking unit presents hold-down elements above and below the geometric mid-plane of the decking unit, and presents shear-resisting elements below the geometric mid-plane, which cooperate in the composite floor construction to achieve the composite load carrying capability of the floor. The decking unit is fully nestable in jam-free relation with others of the decking unit for packaging, storage and shipment. A side joint of the overlap type is provided which is laterally adjustable to facilitate spreading or drawing together of the decking units thereby to accommodate camber or sweep in the decking units, deviations from the specified spacing between the supporting beams, and the like. |
