ABSTRACT:
A concrete supporting bridge overhang bracket system which can be lifted and transferred in gang fashion from a first section of a bridge after it has been formed to a subsequent section. The system includes a series of longitudinally spaced apart laterally extending overhang brackets to which concrete forms are secured. A lift bracket assembly is attachable to a pair of overhang brackets and can be clamped to the deck to support the overhang brackets and the forms from the deck so that the brackets can be disconnected from the deck. Once disassembled, the lift bracket assembly can be supported by a crane and unclamped from the deck, the crane thereafter moving the lift bracket assembly, the overhang brackets and the forms to the subsequent section. Also disclosed is a pivotably adjustable edge form which permits the outer edge of the deck to be vertically inclined irrespective of the horizontal inclination of the deck. Also disclosed is a sleeve member disposed about the hanger rod of each overhang bracket so that after the deck is poured the rod can be disconnected from the form supporting overhang bracket from the surface of the deck.
