Structural supporting system for concrete construction forms

In a structural supporting system for temporary support in concrete falsework construction including a series of adjacent overlapping form beams and a plurality of cooperating bracket means positioned along the length of said adjacent form beams, the improvement comprising:

• at least one intermediate bracket between opposite free ends of said overlapping form beams and having a vertically extending, complementary configured elongated body for receiving the overlapping form beams therein, and adjustable gripping means for at least partial gripping engagement and support of each of said overlapping form beams following desired positionment of said at least one bracket means along said overlapping form beams, the height said intermediate bracket being changeable for different size form beams to increase or reduce the span of said overlapping form beams, said adjustable gripping means including generally vertically adjustable and opposed gripping surfaces for engaging upper and lower surfaces of said overlapping form beams, said vertically adjustable surfaces positioned below said overlapping form beams are also arranged at different heights to accommodate overlapping form beams of different heights, said adjustable gripping means includes two outer bearing elements at substantially the same level for underlying and engaging to spaced outermost overlapping form beams and a lower lever intermediate bearing element for underlying and engaging an intermediate vertically larger overlapping form beam, said intermediate bearing element being connected to threaded adjustment means for vertically adjusting the intermediate bearing element and said intermediate bearing element also engaging said outer bearing elements for simultaneous vertical adjustment therewith.
