ABSTRACT:
A floating roof for use in a storage tank for liquid petrochemical products has a frame comprised of girders having grooved slots in top and opposite side surfaces thereof along substantially the entire lengths of the girders. The slots are capable of receiving threaded fasteners and flanges at any location along the length thereof, permitting cross girders to be bolted to main girders at virtually any location along the length of the main girder and deck sheeting to be bolted to the tops of the girders at virtually any location along the length of each girder, without the need to drill holes. Adjustable legs for supporting the floating roof on the bottom of the storage tank are mounted on the girders, and are coupled to the junction of a main girder and a cross girder by a support housing assembly. A manway assembly and bleeder vent assemblies are also coupled to girder junctions. The bleeder vent assemblies include well support angles mounted on opposite pairs of spaced-apart girders together with a bleeder guide assembly which supports a leg. The floating roof includes pontoons, each of which is coupled to the girders by mounting arrangements including a one-piece saddle having an intermediate arc shaped cradle portion for receiving the pontoon and an elongated strap extending around the pontoon and having opposite ends bolted to the girder through the opposite ends of the saddle either directly to the girder or to a mounting bracket attached to the girder.
