ABSTRACT:
An expansible bottom structure for a fiberglass reinforced plastic tank allows a lower portion of the tank side wall structure to expand radially outwardly without significant deformation of its original shape.
The improvement includes a fiberglass reinforced plastic batten having an upper portion bonded to the cylindrical side wall of a tank, a lower portion bonded to the bottom of the tank, and an intermediate arcuate transitional portion adapted to flex under tension to a less arcuate position. Such permissible flexure of the batten transitional portion enables the tank side wall structure to expand radially outwardly under hydrostatic load, while preserving substantially undeformed the desired shape and characteristics of the lower portion of the side wall structure. The batten provides the sole fluid-containing connection between the side wall structure and the tank bottom.
