Abstract
A method and apparatus for making swimming pools wherein all the pool walls are formed from sheet metal panels joined together at welded junctions. The method and apparatus is characterized by constructing the bottom wall of the pool from a plurality of bottom wall panels provided with edge flange configurations that mate with edge flanges on adjacent panels and thereby facilitate alignment of the panels during assembly. The mating edge flanges of the panels are further adapted to locate the top surfaces of the panels in co-planar relationship to provide a flush pool bottom. In addition, the edge flanges of the panels are adapted to form weld receiving grooves that result in non protruding welded junctions between the panels. The present method is further characterized by constructing the side wall panels with side wall bottom flanges that are welded to the periphery of the sheet metal bottom wall which bottom flanges are laterally yieldable under thermally and hydrostatically imposed stresses on the bottom wall.
