Abstract
Described is a universally usable and durable cover structure formed of a framing and a flexible plastic sheet. The framing consists of a metal grid structure onto which the flexible plastic sheet is shrunk or welded. In a preferred embodiment shown in FIG. 3, a thinner and closer-meshed mesh structure overlays the grid structure 1. This embodiment employs an upper and a lower plastic sheet 2a and 2b, respectively, connected to one another in such a manner that the grid structure and mesh structure are sealingly enclosed therebetween. Further described are preferred uses of the cover structure as for the construction of water retention structures.
Claims7
A cover structure comprising:
- A. a substantially rigid grid-like frame structure comprising two sets of rod-like members, the rod-like members of each set being in spaced apart substantially parallel relation to one another and in crosswise relation to the members of the other set;
- and
- B. a pair of shrinkable plastic sheets, each covering one side of said frame structure and adhered thereto, said sheets
- (1) cooperating to substantially enclose the frame structure,
- (2) being shrunk to be under edgewise tension between the members of the frame structure, and
- (3) being bonded flatwise to one another through the spaces between the members of the frame structure.
