Abstract
828,467. Roofs. SILBERKUHL, W. J. April 17, 1957 [Jan. 30, 1957], No. 12503/57. Class 20(4) A concrete shell roof comprises prefabricated concrete shells 1 curved to span the building transversely and sloping in opposite directions in the longitudinal direction of the building, the adjoining edges of the shells providing mutual support between the shells at the ridges and valleys formed by the shells. The adjoining edges of the shells may directly abut or they may be thickened and supported by curved I-section steel girders. 2 which may be strengthened by tie rods 3 and grouted in position. The shells may be provided with prestressing cables running inside tubes built into the shells.
