Abstract:
A structural member assembly comprising:(a) two or more longitudinally adjacent shafts, each with an outside facing plate having an inner and outer face, an edge of the outside facing plate forming a first vertex with an enclosed plate having an inner and outer face, whereby opposite edges of each plate are parallel to the first vertex such that the two plates form a substantially triangular cross section with the opposite edges of the plates defining a third plate space therebetween;(b) each adjacent shaft further having a leg surface with an outer face extening from the opposite edge of each plate to form two second vertices such that the leg surface extends only partly into the third plate space and do not join with the leg surface of an adjacent shaft at any point;(c) a basic structural unit comprising a first and a second adjacent shaft whereby the second adjacent shaft is secured in a position such that the outer face of the leg surface extending from the second vertex with the opposite edge of its outside facing plate abuts the outer face of the enclosed plate of the first adjacent shaft near its first vertex, thereby defining a first interface, and the other leg surface of the second adjacent shaft abuts the outer face of the enclosed plate of the first adjacent shaft side near its opposite edge of its enclosed plate, thereby defining a second interface.
