Claim 1

A prefabricated core element for the construction of partitions and bearing walls of buildings, said core element having the shape of a substantially parallelepipedic plate having peripheral edges and comprising a composite of a first section formed of a thermal insulation material having the face thereof constituting one face of the core element and a second section having the face thereof constituting the opposed face of the core element and being coextensive throughout the area of said core element with said first section, said second core section being made from a lightweight, rigid and strong loadbearing material having a U-shaped cross section with enlarged parallel peripheral edges having load bearing capacity and occupying the major portion of the thickness of the core element at least along said peripheral edges, said first member filling the interior of said U-shaped second member and extending over the peripheral edges thereof to form an entire face, said second core section having on at least one of the edges thereof a plurality of longitudinal grooves and a plurality of blind bores formed in said grooves extending into said core at an angle with respect to the edge surface, said grooves and blind bores being adapted to be filled after juxtaposition with a like prefabricated element with a settable binder injected therebetween.
