<p>A machine for manufacturing prefabricated building components formed of an insulating concrete mix, comprises means in which to cast the insulating concrete mix and comprising an elongated mold having a bottom wall and side walls; means to cast the insulating concrete mix into the elongated mold along the length thereof and comprising a feeding hopper; and shaping means to shape the upper surface of the insulating concrete mix when it has been cast within the elongated mold, and to provide at least one deep depression in the concrete mix within the elongated mold, which depression has a generally rectangular cross section. The shaping means comprises at least one elongated shaping hull, the shaping hull extending below the upper edges of the side walls of the mold; the shaping hull has an upper level, a bottom molding surface, side molding surfaces extending between the upper level and the bottom molding surface, an upstream end and a downstream end, and is adapted to form the depression in the cast insulating concrete mix with the depression extending longitudinally of the elongated mold, the upstream end of the hull being provided with means to force the mix downwardly and including a face sloping downwardly and rearwardly from approximately the upper level, the upper level being above the casting level in the mold, and further comprising an inclined plate hingedly attached at its lower end to the upper portion of the elongated shaping hull, and hinged at its upper end to the hopper. The machine of the invention includes means to control the height of the plate and means to move the elongated shaping hull relative to the elongated mold along a direction parallel to the sides of the mold whereby the hull penetrates into the insulating concrete mix to compress the mix downwardly to form the depression of generally rectangular cross section. The prefabricated building components manufactured by means of the apparatus of the invention are used as panels, roofing units and floor blocks for either load bearing or non-load bearing purposes.</p> |
