  • Patent number: 4076777
    Abstract: Each one of a plurality of sector-shaped form members for a reinforced concrete or postensioned roof supported by a circumscribing wall, footing, columns or the like of a large building structure has an eyebolt located near its center of gravity to permit raising and lowering the form. The forms are lifted by this eye and successively positioned with their wide ends supported by brackets fastened to the circumscribing walls, footings, or columns and supported near their narrow ends by a central staging structure. If the building structure has circular walls or columns for supporting the roof, a pivoted station at the wide end of each form member provides a work platform for access to the bracket fastening means. When all of the forms are in place, their narrower ends define an opening which is centrally located. The forms are then covered by a layer of reinforced concrete. Holes are left in the roof at each eyebolt.
