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.
Claims16
A building element for the construction of floor and roof grids comprising:
- a beam, girder or truss having two ends and which is provided in the upper portion of at least one of said ends with a longitudinally protruding first projection of a vertical dimension less than the vertical dimension of the beam, girder or truss, the element being further provided with a first recessed portion disposed in its upper surface, of a width not less than the width of said projection and of a depth not more than half the vertical dimension of the beam, truss or girder at said ends, said first recess beginning a distance from said end of the element which is greater than the protruding length of the said first projection but which is small relative to the entire longitudinal length of the element, wherein said beam, girder or truss is symmetrical and is provided with a second protruding projection and a second recessed portion beginning at the other of said ends symmetrically disposed with respect to said first projection and said first recessed portion at said at least one end, and wherein said recessed portions beginning at each said end consist of a single central recess extending over the entire central portion of the element at equal depth.
