Abstract
A building element for the construction of self-supporting interlocking grids which may be used, for example, as floors or roofs, comprises a beam having a longitudinally protruding projection at each end, and having at least one recess of sufficient size to receive the longitudinally protruding projection from a second identical beam. The projection from a third such beam rests on the recess of the second, the projection of a fourth such beam rests in the recess of the third, and the projection of the first beam rests in the recess of the fourth. Thus, the four beams are rigidly connected in a statically determinate self-supporting manner. An entire grid of such joints may be made as well as light arched and domed roof structures.
