Abstract
A swimming pool wall, for placement in an excavation, is made up of a series of bendable plates having only vertical flanges for stiffening while permitting shaping the wall to a selected outline. A resilient coping strip embraces the upper edge of the wall and houses a rigid metal bar to retain the upper edge of the wall in the desired configuration while other braces, at the lower edge of the wall extend from the plates to the outer edge portions of the flanges to securely maintain the lower edge of the wall in the desired configuration. Vertical Z-shaped bars are secured to certain of the plates to further stiffen them and further braces, secured to the flanges, extend diagonally upward into a concrete apron, selected ones of the diagonal braces carrying a form plate for defining the outer edge of the apron. Rigid bars are used to hold corner plates to a desired curvature during assembly of the pool wall and its placement in the excavation. After back-filling and forming the apron, those bars are removed.
