Pre-stressed, pre-fabricated concrete supporting structure for a mobile home

Abstract

A new supporting structure for a mobile home comprising pre-stressed concrete and a method for making same. The supporting structure comprises a rectangular floor, supported by beams on the lower surface of the floor. A pair of large longitudinal beams are formed on the lower surface of the floor adjacent the longitudinal edge of the floor. A plurality of smaller transverse beams are formed on the lower surface of the floor connecting the longitudinal beams. Both the longitudinal and transverse beams are pre-stressed. Means for attaching wheels and a towing hitch are provided. The supporting structure is cast in a single piece in a bed provided with channels for the longitudinal and transverse beams. The beams are pre-stressed in a conventional manner either by pre-tensioning or post-tensioning tendons. After the concrete has set and the tendons anchored, the supporting structure is lifted out, and wheels and a towing hitch attached. Walls and the upper structure are later attached by means of studs cast in the concrete floor.
