Abstract

Method of producing a precast hollow slab or beam member made of standard or precompressed concrete comprising the following steps in sequence: continuous casting by means of a forming machine on a steel track on which suitably arranged pre-compression rods have already been laid and tensioned, setting and hardening of the casting, thereby obtaining a compact article, releasing the tensioning of the rods and subsequent pre-compression of the article, and carrying out two mutually inclined cuts at least at one end of said article.
