Structure for the construction of swimming pools, characterized in that it consists of: rigid vertical sections (3) each comprising at least one outer face (5) and one inner face (8) provided with an opening (7), at least one relatively flexible base band (1) comprising at regular intervals means of securing the said outer faces (5) in such a way that only small spaces remain between these successive faces (5), assembly sections (4) or keys which are relatively deformable transversally and capable of fitting on the lateral ends (9) of the said inner faces (8) to fix together and fill in the varying space between these ends of two successive sections (3).

A method for fabricating a pool mold comprising the steps of creating a recess, the recess having the general shape and contour of the desired finished pool and is installed with support materials and surface references. A layer of forming material is place over the support materials and surface references and formed to desired contour and grade. The forming material has substantially uniform coefficients of thermal expansion and heat transfer. The surface of the recess is sealed and coated with a release agent. A mold is then fabricated within the recess.

An apparatus and method is disclosed for an improved swimming pool comprising a base forming the bottom of the pool. A sidewall extends about a peripheral edge of the base. The sidewall has an inner surface facing an interior of the pool, and an outer surface facing an exterior of the pool. An inner coating is disposed on the inner surface of the sidewall and on the base for affixing the sidewall to the base and for forming an interior surface for the pool. The sidewall comprises a plurality of flexible panels, which define a plurality of vertical joints. A plurality of upright supports are affixed to the outer surface of the sidewall at the vertical joints. A plurality of contour panels are affixed to the outer surface of the sidewall proximate the vertical joints and define a plurality of cavities therebetween. The cavities contain the upright supports. A plurality of vertical support columns are molded within the cavities for supporting the sidewall and integrally joining the flexible panels.

A precast wall panel has forms for flanges and a lintel embedded in place. Upon erection of the panel over a precast footing having an anchoring trough, this trough, the flanges and lintel may all be cast on-site, with appropriate reinforcing present within the core volumes that are filled with binder.

A swimming pool construction is of the type using metal fabricated walls and a plastics liner covering the walls and a rigid excavated pool base. The metal fabricated walls include spaced inner and outer panels defining therebetween a crawl space. The inner panels define the inner surface of the pool. The outer panels engage the surrounding soil. The panels are mounted on support members and rails supported on pairs of piles at spaced positions around the periphery of the pool. The panels are supported initially on bottom rails which are used as forms to cast a concrete layer therebetween. The panels are supported in spaced positions temporarily by a rigid arch form into which is cast a cast concrete arch allowing the rails and the arch form to be removed for re-use. The arch is cast integrally with a concrete floor which sits on supporting panels bridging the rails and resting on flat top supporting surfaces of the concrete piles. A top concrete cover is cast onto bridging panels spanning between the inner and outer walls and carried on the top of the arches.
