Method of manufacturing vertical scaffolding element comprises shaping metal band and stamping flat to form dihedral then folding to obtain star shaped part comprising radially projecting sockets

摘要

The scaffolding element (16) is composed of a tubular section (14) provided with a number of radially projecting sockets (17) for coupling to the end of a horizontal scaffolding crosspiece. The manufacturing method comprises shaping a plane metal band and stamping it flat in several regularly spaced places so as to form dihedral imprints with a rounded edge. The stamped bands are then folded to obtain a star shaped part (11) comprising the sockets. An Independent claim is included for the scaffolding element.
