ABSTRACT:
The present invention provides a membrane structure for a liquid gas storage tank. The structure is characterized in that the bottom wall of the membrane comprises a number of elongated corrugated members arranged in a square-lattice pattern, and each member has a pair of spaced, parallel, longitudinally extending corrugations. Also, the members are assembled by joining one end of each corrugated member to substantially the mid-point of another corrugated member extending normal thereto, and each opening between the corrugated members is closed and made liquid tight by a thin plate.
Preferably, each corrugated member is a sheet member of U-shaped cross-section, having a pair of vertical flanges of equal height, located between a pair of sheet members of L-shaped cross-section which are arranged back to back in spaced, parallel relationship, the top edges of respective adjacent vertical flanges of said L-shaped and said U-shaped members being continuously welded together.
