摘要

The building element frame is quadrilateral in shape and formed from two isosceles triangles joined by a common base. Each element has a concave face and an opposite convex face symmetrical with respect to a bisector plane passing through the opposed summits of the two isosceles triangles. The element has, along each edge of one of its faces, a projecting rib with holes for bolts or screws for fixing adjacent elements, while a diagonal projecting rib extends between the edge ribs bracing the element.
