Abstract: A swimming pool structure comprises a plurality of buttress post assemblies spaced about the perimeter of the pool and servicing to support the pool wall. Each of the assemblies include a horizontal foot beam with a vertically oriented buttress post connected thereto by angle brackets. Laterally located beams and plates interconnect the sides of adjacent buttress post assemblies and the inner ends of opposing foot beams from opposite sides of the pool are directed under the floor of the pool and are secured together.

Abstract: The invention relates to a pool liner assembly that comprises a main liner subassembly and a secondary liner subassembly. The main liner subassembly comprises a main liner sheet for lining the walls of a pool, and a main liner clip attached to the top edge of the main liner sheet for attaching the main liner subassembly to a coping of the pool. The secondary liner subassembly comprises a secondary liner sheet overlapping an upper portion of the main liner sheet and having a bottom edge that is attached to the main liner sheet, and a secondary liner clip attached to the top edge of the secondary liner sheet, for attaching the secondary liner subassembly to the coping of the pool. The secondary liner subassembly may be attached to the front or back of the main liner subassembly. After the portion of the assembly facing the sun has faded, it can be removed to reveal an fresh underlying portion of the assembly.
