Improved recoverable vault, characterized essentially because it is provided with an internal reinforcement framework, which is constituted by two U-shaped rods, which are cut orthogonally and in which, the intersection point is welded a nut, while the ends of the rods jointly carry axially orificeed plates, all arranged in such a way that in the operation of molding a rod, the frame is embedded in it, the lateral branches of the u-bars constituting the frame being arranged, centered on the lateral faces of the vault while the transverse branches are located in the smaller base of said vault, in whose center of the base the nut will be housed with its through hole, while each one of the lateral faces of the vault and in proximity to the vault. The larger base will have a through hole coaxial with that of the plates that will act as internal reinforcement. (Machine-translation by Google Translate, not legally binding)
