Abstract: Method of production of concrete double-wall panels, wherein a layer of concrete is poured into the bottom of a mould, covering a welded wire fabric and the lower end portion of vertical structures of rods; subsequently a second layer of concrete is poured into the upper part of the mould, over a plate of insulating material arranged at a height on the vertical structures, said concrete covering a third welded wire fabric fitted to the upper end portion of the vertical structures; after which the two layers of concrete are left to cure simultaneously.

Abstract: The invention relates to an automatic system for the construction of buildings, which uses a supporting structure (1) mounted on displacement rails (2), covering a space holding the building to be made, the construction taking place floor by floor, in such a way that all the parts of the construction are made in the installation itself, thereby defining a rigidly secured constructive assembly, based on reinforced concrete, in the building of each floor; for this purpose a number of platforms (4, 5) move in vertical displacement mode on the supporting structure (1), on which the construction operations are performed at the level of each floor, and include stores (3) in which the elements used for the construction are held, with a gantry crane (10) in the upper part for moving the construction elements.

Abstract: Installation to produce reinforced concrete parts, including a first conveyor (1) on which the model of the parts to be produced is carried out, a second conveyor (2) for the part drying and an outlet (3) to withdraw the formed parts, being formed the first conveyor (1) of a metal sheet band, on which a marking pencil (12) carries out the drawing to determine the forms of the parts, forming the cases of the mentioned forms respect to some continuous side bands (11) which are situated on the metal belt (1) in combined movement with it.
