This block consists of a solid or hollow body (1) profiled with shoulders (2, 3) and with receiving recesses (4, 5) ensuring, by juxtaposition and superposition, the self-stabilised jointing of the load-bearing surfaces. It is particularly intended, by virtue of its functional shape, to allow self-alignment for the construction of walls and frames of a building. <IMAGE>
