Patent ID: 8801422

Claim:
A machine to produce structural elements for building trade, the structural elements being made of cement material with one or more inserts made of polymer material, said machine moving in step wise advance, said machine comprising: a molding member open at a top side and selectively opened and closed from a lower side by a movable plate, said movable plate being movable by means of an actuator; a loader for said inserts; a rotary brush connected to said loader at a lower part of said loader and able to brush an upper surface of the structural element when said structural element deposited on a ground; a depositing member for said cement material; wherein said loader and said depositing member are selectively and alternately positionable above said molding member by respective drive members configured to move the depositing member and the loader on a plane above said molding member, from respective inactive positions to respective operating positions, in order to load and deposit from above, respectively, said inserts and said cement material into said molding member, in order to achieve said structural elements, wherein said loader includes a movable positioning tray, the movable positioning tray having inside it a plurality of positioning elements for the inserts, open both at a top and also at a bottom, selectively movable between a first inactive position and a second inactive position, the first inactive position having the bottom closed to contain the inserts which are loaded from above inside said positioning elements, and the second operating position in which the movable positioning tray is open at the bottom and the movable positioning tray is above said molding member, in order to allow the inserts to be loaded into the molding member from above; and a thruster unit located above the molding member and fitted with a comb element that positions the inserts inside the molding member when the positioning tray is above the molding member, wherein after a first group of said structural elements has been formed, the movable plate is opened, and the structural elements are deposited on the ground, and thereafter, the machine advances one step, and during the advancement of the machine one step, the structural elements are surface finished by the rotary brush.
