Recoverable vault, of the type that is constituted by a trunk quadrangular pyramid, hollow, lacking major base and that in its smaller base centrally involves a nut, whose orifice communicates with the interior and exterior of the piece and serves to attach a screw that it acts as an extractor, essentially characterized by a block of resistant material, a progressive and/or a series of grooves and is retained to the upper face of, by means of a screw that threads on the nut and its plug, for which purpose it presents a threaded axial hole, with its bevelled peripheral edge, thereof arranged in such a way that when the salt is removed from the mold. Tadilla, the block is embedded in the concrete to which it adheres strongly by the steps or groove that it presents, determining a centered hole, in the vault of the slab for the posterior anchoring cover plate that will be joined to the block through a shank central.
