ABSTRACT:
Principal members of structures are manufactured as foldable assemblies of like size and shape structural members, foldable for handling, packaging, shipping, and storage, and unfolded into their respective principal member configurations. Each like size and shape structural member has its opposite end surfaces formed on a sixty degree bias, whereby one longitudinal edge surface is longer than the other opposite edge surface, thereby creating opposite trapezoidal side surfaces. Each of these members has two spaced holes formed along its centerline, and each of these holes is equally spaced from a respective bias end. Regarding relative design dimensions, the respective longitudinal centerline length of each like size and shaped structural member is given the formula dimension, L, then the space between holes, X, is equal to 0.464 L, and the space from each hole to the centerline end, Y, is equal to 0.268 L. Using fasteners passing through respective aligned holes, these like size and shape structures are arranged as pivotal members, in two adjacent parallel planes, each plane staying within the thickness of the thickness size of one like size and shape structural member, to become, when unfolded, a complete principal member of a structure, in reference to 360 degrees, either in a vertical plane or a horizontal plane.
