摘要
A three-dimensional construction element comprising a body of generally polyhedral form with an aperture therethrough. Said element comprises at least one peripheral rib forming a statically indeterminate frame the neutral axis of which is located in a plane parallel to the planes defining the ends of the element having the aperture therethrough, and in that the grooves located beside the rib form, separately or together, a geometric figure which is complementary to the figure formed by the rib. (FIG. 1).
