Beam for a composite floor comprising integral shear connectors

摘要

Methods of manufacturing a composite floor comprise securing together cold rolled galvanised steel sections 1a so as to form a series of spaced apart parallel beams 1. Steel sheets 2 are positioned so that their edges rest on the beams. Concrete is poured onto the sheets to form a deck 4. The beams may define troughs T into which the concrete flows, or the sections may have tabs or holes, in order to key the deck to the beams.
