ABSTRACT:
A light weight support box is formed as a rigid beam from a single thin sheet of inexpensive plastic. The single sheet forms the bottom and side walls of the box and serves as the tensile member of said beam. The interior of the box is insulated to protect the sheet from thermal degradation of its tensile strength. The one-piece sheet, forming the walls and bottom, is secured at the open edge of said box to a reinforcing bar members to which beam compressive forces are transfered by the plastic sheet. The box is particularly suitable for roof top mounting of a passive solar water heating system, including either a solar collector, or absorber, panel or a hot water storage tank, or both in a back-to-back assembly.
