摘要

Improvements in devices for the manufacture of prefabricated structures for the construction with hollow core, which are characterized by being constructed on the basis of concrete structures and the like, together with a source of pressure by fluid; comprising in combination a mold, means that can be extracted to provide access to said mold, whereby the concrete mixture can be formed therein; means for producing vibration, associated with said devices to contribute to the compaction and dispersion of said mixture within said mold; and, at least, a core shape in said mold; means for coupling and retracting said core form inside and outside said mold; at least one water extraction component in said mold; and means for coupling and retracting said water extraction component inside and outside said mold.
