Abstract
The sidewall of a swimming pool is made up of bendable sheet modules fastened together at their ends. One end of each module is bent outwardly to define a vertical flange, the other end being unbent. A step is provided in the flanged end of each module of a depth to receive the unbent end of an adjacent module in coplanar relation to the unstepped area. Headed fasteners secure the modules together, their heads being housed in nested recesses in the overlapping portions of the modules to provide a smooth and continuous inner surface for the wall, the nested recesses serving to transmit forces from one module to the next without placing shear stresses on the headed fasteners.
