ABSTRACT:
A concrete form support assembly for the form structure needed to pour concrete for bridge floors and the like. Such form structures include a plywood flooring supported at a desired uniform depth relative to the plane of the upper surface of the bridge beams, depending on the thickness of the concrete called for by the specifications. The plywood flooring is supported by ledgers which extend laterally between the bridge beams and stringers on the top thereof which extend longitudinally and parallel with the bridge beams. The ledgers are supported by vertical bolts hanging from hanger bars on each side of each bridge beam, with support plates at the lower end of the vertical bolts to support opposite ends of the ledgers, and threaded nuts below the support plates to adjust the plates and ledgers thereon up and down. After the plywood flooring has been put in place, workmen cannot thereafter reach the adjusting nuts from above to make final depth adjustments of the flooring. The support assembly in accordance with the present invention provides depth adjustable hanger bolts adjustable from above the plywood flooring after it has been put in place.
