ABSTRACT:
A structural supporting system for use as a temporary support in concrete falsework construction and the like is disclosed. The structural supporting system includes a series of overlapping form beams and a plurality of cooperating brackets positioned along the length of the overlapping form beams. A bracket is provided at the opposite free ends of the overlapping form beams for mounting the overlapping form beams in the temporary concrete construction support. At least one other bracket, and preferably two other such brackets are positioned intermediate the opposite free ends of the overlapping form beams in order to provide adjustable extension and collapse of the overlapping form beams, so as to increase or reduce the span of the overlapping form beams, as desired. The end brackets at the opposite free ends of the overlapping form beams include an integral support ear which extends laterally outwardly from the end brackets and an adjacent free end of the overlapping form beams for attachment to a fastener suspended from the concrete form construction or other support. The intermediate bracket or brackets include adjustable upper and lower opposed gripping surfaces for engaging corresponding upper and lower surfaces of the overlapping form beams, in adjustable mounted relationship thereto.
