Abstract: A building unit is made up of a generally straight elongated portion and a pair of generally straight, substantially parallel, spaced-apart legs extending in the same direction therefrom. Units may be used in various combinations, in particular to form a building frame structure having two generally U-shaped portions with limbs thereof connected by connecting members, in the shape of "Demi-Cubic" frame.

Abstract: Laminated building panels are constructed within metal framing members having external edges to protect the panel skins from crushing. These frame members are essentially Z-shaped in cross-section in order to provide a degree of flexure during panel manufacture and use. The flexure accommodates variations in the dimensions of core and skin materials and enables the manufacture of fully laminated panels without excessive lamination pressure or the use of mechanical fasteners. Delamination stresses during use are also accommodated by the "Z" framing members. Panel to panel connections are facilitated in all configurations by the use of connectors of an essentially open triangular cross-section dimensioned to mate with, promote alignment, and wedge into, the "Z" shaped frame member.
