摘要 A light-weight, high-strength beam member for use in concrete form assemblies. An end plate (16) is secured by weldment to each end of a pair of channel members (14) arranged in a back-to-back, spaced-apart relation. The channel members (14) include a pair of transversely opposite leg sections (20a, 20b) with inturned terminal edges (22a, 22b) and an interconnecting web section (24). The terminal end portion of the web section (24) is foreshortened (38) by one-half the thickness of an end plate (16). In assembly, an end plate (16) rests against the terminal edge (38) of the web sections (24) and is partially recessed in the leg sections (20a, 20b) and inturned edges (22a,22b) of the channel members (14). Upon welding of the end plates (16) to the channel members (14) a high-strength end connection is created which permits full strength beam assemblies to be constructed by interconnecting end-to-end a plurality of individual beam members.
