Abstract (en)
[origin: EP0013998A1] The invention provides a shuttering or formwork (10) for conventional or prefabricated building, of the "lost shuttering" or "permanent formwork" type and a process for providing walls with said shuttering. The shuttering has two parallel flat parts (11, 12) and parallel longitudinal internal slots or hollows (19, 20) for receiving the concrete; in cross-section the slots or hollows are of substantially regular triangle shape, the adjacent slots or hollows being of opposing arrangement. For use as floors, the shutterings may have some slots or hollows with longitudinal passages (22) through a flat part to form ribs or joists of concrete. The process contemplates the disposition of reinforcements in the slots or hollows, in the case connecting adjacent slots or hollows with transverse cross stiffening brackets, in case arranging through pins or needies to retain a plaster lath and casting concrete into the slots or hollows.
