ABSTRACT:
In order to provide, in a composite structural assembly comprising a plurality of metallic support members disposed in side-by-side relationship and a layer of cementitious material disposed on the plurality of support members, for the securement of the support members to the layer of cementitious material in a particularly simple and efficient manner, there are provided spaced lugs which project from each side edge portion of each of the support members, with according to one aspect of the invention the lugs presented by adjacent side edge portions of adjacent support members being interfitted and being embedded within the layer of cementitious material. According to an alternative aspect of the invention the spaces between the lugs presented by each of said side edge portions are each in alignment with respective ones of the spaces between the lugs presented by the other of said side edge portions, reinforcement rods being disposed through said spaces, with the lugs and the reinforcement rods being embedded within the layer of cementitious material.
