Abstract: Prefabricated elements juxtaposable for making partitions and walls of buildings, having each one the shape of a parallelepipedic plate comprising a core provided on at least one edge with longitudinal grooves in each one of which open cavities sloping with respect to the edge surface, the grooves and cavities being filled after juxtaposition of the elements with a settable binder injected under pressure, the core consisting of a light-weight, rigid and strong material and being formed on its portions comprising said grooves with means for communication between the grooves, said means being filled with binder upon its injection under pressure into the grooves and cavities.

Abstract: A method of assembling and conveying pre-fabricated wall elements for buildings having their edges formed with longitudinal assembling grooves with injection of a settable binder therein, consisting in disposing said elements separately on a support with juxtaposition thereof in the proper wall-forming sequence, assembling same through injection of said binder and conveying the assembled elements resting on said support to the building site.
