Abstract
A floating roof for use in a storage tank for oil or other 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. In the bleeder vent assembly a cover mounted on the upper end of a leg is raised above a well formed by well support angles in response to upward vertical movement of the leg to vent the underside of the floating roof. The well support angles are mounted on opposite pairs of spaced-apart gir…
