Abstract

Installation for the manufacture of elements of lightweight materials, cellular structure, by casting in molds, a mass of concrete or ceramic, according to the process of "chain" casting, pre-hardening, finishing and passage through the autoclave, being characterized said installation because it comprises a set of rigid, large-capacity parallelepiped molds, preferably in a small number, rolling on rails carrying movable portions by means of fixed wheels on the walls of said molds, according to a preferably closed circuit, in two overlapping tracks , the lower path being at the level of the casting, the previous hardening and the finishing, and the track superimposed on the level of the return of the molds towards their preparation before casting, the said molds being directed from the casting site to the site from the previous hardening, then to the finishing, and then, once the finished mass is removed, returning to the Preparation and then casting, the said molds carrying a vertically sliding bottom, with a small play between the lateral and transverse walls of the molds mounted rigidly, said bottom of the mold being constituted by a rigid board, preferably metallic , suspended in a removable manner on stirrups provided in the inner lower part of the walls, said board being provided, on its upper surface, with grooves, of suitable profile and spacing, or carrying movable carriers vertically, susceptible in an outgoing position , with respect to said surface of the mold, to form said grooves, and these being intended for the guidance and insertion of movable elements intended for finishing and transporting the mass to be treated; the circuit being completed by means of a lifting and lowering device formed, for example, by hydraulic jacks fixed in a pit, and supporting a removable portion of the rails on which the wheels of the mold rest, on the finishing track, having said device its prolonged course in the pit, so that the walls of the mold descend during the descent, releasing the bottom of the mold, having stirrups in the pit to stop and detach from the walls the bottom of the mold during its descent, up to the level of the finishing position, said lifting and lowering device having, on the other hand, its prolonged course above the finishing level, to reconstitute the mold during lifting, and to bring the position of the rails from the finishing track to the track superimposed return; the closed circuit being by means of a second descent device formed, for example by hydraulic jacks fixed in a second pit, and intended to carry the molds of the track superimposed on the lower track; a rolling frame tool holder, carrying the finishing and cutting tools, also being provided on the lower track, before the lifting and lowering device; the installation also comprising a transverse load beam, suspended by integral gripping elements of the same winch, and provided with fingers, allowing lifting the carrier sleepers with the raw dough finished and cut, from the bottom of the mold, to a hardening enclosure or of cooking, on saver cars, that return without load, leaving the mass in the enclosure.
