Method, apparatus, mould supporting structures and installations for the improvement of the efficiency of the methods of making prestressed concrete products

摘要

Some self-supporting screens for closing the mold head, some self-supporting separating screens, group positioning devices and group tensioning devices, are used. A series of novel installations for the shock heat treatment, stripping and removal of the products enables by combination with the foregoing means, improvement with respect to known processes, on the one hand of the manufacturing process and on the other hand enables stripping to be brought forward.
