Abstract
727,023. Roofs; domes. MOTHERWELL BRIDGE & ENGINEERING CO., Ltd., and FOSTER, R. H. Oct. 22, 1952 [Oct. 12, 1951], No. 23820/51. Class 20 (4). [Also in Group XXIX] A domed roof for a storage tank or other circular structure comprises a peripheral curb, a plurality of upwardly-convex radially-disposed ribs which abut at their outer ends against the curb and at their inner ends against a centrallydisposed crown member so that each pair of diametrically opposite ribs has rigid continuity through the crown member, and roof sheets which are secured together to form a continuous spherical membrane attached to the curb and supported by, but not attached to, the ribs and the crown member. In an oil storage tank described (Fig. 3), the ribs 1 are H-section girders and the curb may be (a) a continuous L-section ring 7 (Fig. 7) welded to the tank wall 2, with or without an annular plate 8 welded to both the ring 7 and the ribs, or (b) a J-section ring 9 (Fig. 9) welded to the tank wall 2 and having strengthening web plates 10. The outer end of each rib is cut away and welded to a baseplate 12 which is bolted.to a cap plate 13 supported by a stiffener 14. The crown member 3 is formed of two annular plates 3a welded to two vertical cylindrical plates 3b, 3c. Concentrically disposed purlins 4 extend between pairs of adjacent ribs, the sets of purlins 4a, 4b, 4c and 4d being of I, #, I and # section respectively. Short sub-rafters midway between each pair of ribs extend from the curb to the innermost circle of purlins and are secured to the roof sheets. Diagonal bracing may be provided between pairs of adjacent ribs, particularly between two diametrically opposite pairs only.
