Claim:
A building module having a box structure with top, bottom and opposed side walls, and comprising a plurality of interconnected coaxial discrete module segments which individually comprise a unitary open-ended rigid box structure molded from a composite material, each segment having integrally formed top, bottom and opposed side walls that combine to define a box with an open interior and opposed open ends, the segments being bonded together in an end-to-end relationship such that the side walls of the segments combine to form the side wall of the module, the bottom walls of the segments combine to form the bottom wall of the module, and the open interiors combine to define the open interior of the module, at least one of the segments having an integrally molded strengthening beam spanning its opposed side walls wherein at least one of the segments has an integral frame by which the module may be lifted, the frame comprising a pair of spaced substantially vertical posts interconnected by upper and lower cross-members, the posts being connected to the cross-members by means of corner plate members, the corner plate members comprising first and second connector portions disposed substantially at a right angle to each other, the first and second connector portions being joined by an intermediate arcuate portion in which part of the post is received.
