Abstract

Abstract A building element or block consisting of empty substantially uniformly sized cans which are assembled in a wall-like structure using mortar joints and without the necessity of embedding the cans in concrete or other cementitious material. Each element consists of first and second pairs of cans standing in a first direction, a third pair of cans disposed intermediate said first and second pairs, the principal axes of which are at right angles with respect to those of said first and second pairs. A seventh can is reduced to flattened condition and positioned between said first mentioned and third mentioned pair of cans, and an eighth can is similarly flattened to be positioned between said second pair and said third pair to serve as weather stops. The assembled element is maintained in such condition by wire cinctures held in position by the rims of said first and second pairs of cans.
