Abstract
A cover for tank is formed from a plurality of panels attached together by cross members. The cover includes means for sealing the panels to the cross members, and means for sealing the panels and the cross members to the tank. The panels are constructed from a multiplicity of edge-to-edge planks. The planks may be connected together without welds, and the panels may be connected to the cross members without welds. The cover may be in the shape of an arch, or the shape of a dome. In another embodiment a dome-shaped cover may be formed from a plurality of panels each having the shape of a section of a circle. Each panel is connected between an adjacent pair of a plurality of radial members arranged in a radial pattern.

A cover for an open-topped structure such as a tank having a cover supporting rim or edge, comprising:
- at least one panel with a plurality of planks forming each panel, said planks connected together edge-to-edge with tongue-in-groove means for connecting plank edges,
- each of said panels having side members extending transversely along the planks at edges thereof, said side members having plank receiving means therein for receiving ends of planks and supporting the planks from the side member,
- each side member having outside edge connection means for transferring load from the planks to adjacent structure parallel to the side member such that said load is ultimately transferred to the cover supporting rim or edge of the open-topped structure, and
