Abstract: A moulded building sheet (1) has opposed side edges (5) of increased thickness with respect to the general thickness of the sheet. The thicker side edges each accommodate a rebate (6) which extends along the respective side edge and into which the free ends of reinforcing wires (7) project.

Abstract: Composite building elements of reinforced concrete having trimmed outer surfaces, formed through the coupling of two flat basic semielements, each of which comprising a continuous metal reinforcement according to a fret-like pattern, formed of a perforated metal laminate, or a latticework or a bent wire net said basic semielements comprising on the outer trimming side also a flat wire net embedded within an initial layer of cement mixture, the fineness of which decreases from the outer surface to said inner reinforcement, so that the complete element provided through the coupling of the two semielements has the two exposed sides perfectly smooth and trimmed; the fabrication and coupling of said semielements being realized by an automatic equipment working in a continuous cycle, comprising at least one feeding continuous rubber belt running over a plane of transverse metal box elements articulated to one another and sidewise guided by C-shaped elements opposite to one another, along the sides of said continuou

Abstract: A prefabricated building module comprising at least two side-walls, a ceiling, and a floor. In one embodiment of the building module, the walls, ceiling and floor each include a thin, continuous layer of a concrete-like material having spaced-apart, open web bar girders embedded in one surface thereof. The two side-walls, the ceiling and the floor are assembled together with the bar girders extending outwardly and are rigidly attached to one another, for example, by welding the ends of the bar girders to one another, thus forming a rigid, box-like building module. The building modules can be formed into a building by placing one layer of building modules with one side-wall of each module adjacent to but spaced-apart from one side-wall of a different module.
