Abstract: A drain for a prefabricated shower stall that can be quickly and easily connected to a drain pipe, even though the drain pipe might be off-center with respect to the shower drain opening. The drain consists of two interfitting parts, a first of which is a drain body designed for attachment to the shower stall, and the second of which is a bushing-like member designed to interconnect the drain body and drain pipe. The drain body has a round opening, with a converging wall, extending through it, and an outwardly extending flange by means of which it can be affixed to a prefabricated shower stall around the drain opening in the stall. The converging wall of the opening in the drain body serves as a seat for the second part of the drain, which has a frustoconical outer wall to make this possible. This second part has a cylindrical bore concentric with its outer wall and is of such size as to extend below the first part, when seated therein, and telescopically receive the drain pipe in its cylindrical bore.

Abstract: A one-story building having a concrete foundation, a wooden roof and interior and exterior walls of precast concrete panel construction, the walls being formed from precast concrete panels and installed in place without benefit of rigid interconnecting joints therebetween. Additionally, the wall panels are connected to the foundation at their bottom ends, and to the wooden roof at their upper ends, by means of nonrigid, as opposed to rigid, connection. Each of the exterior wall panels has an inner, structural slab of steel-reinforced concrete, a thin intermediate layer of a compressive, insulative material and an equally thin outer layer, or skin, of wire-reinforced concrete. The interior walls of the building are interrupted by door openings, or the like, to permit expansion and contraction of each wall segment as an independent unit.
