ABSTRACT:
A structural wall unit for retaining wall structures of in ground swimming pools, whereupon assembly of a plurality of wall units in series, a circuitous pathway is formed which defines the swimming pool shape. In accordance with one aspect of the present invention, each unit includes end surfaces comprising folded portions at the corners thereof for reinforcement of the wall unit, at least one of the surfaces being formed for engagement with a corresponding end surface of an adjacent unit. The units are fastened one to the other so as to form the circuitous wall structure. Each unit includes a base or lower wall for supporting the unit in an upright position and a gusset plate having apertures adapted for cooperation with matching holes on a pair of adjacent folded portions of an end surface, each of the folded portions being adapted to overlie the gusset plate. Upon engagement of the plate with the folded portions, complementary connectors formed in the folded portions engage the apertures so as to secure the plate to the folded portions and reinforce the wall unit.
