Method of manufacturing a vertical scaffolding element, and element thus obtained

摘要

The invention relates to a vertical scaffolding element consisting of a tubular portion provided with a number n of radially projecting sockets, distributed peripherally in a star arrangement, designed for the attachment of one end of a horizontal crosspiece of the scaffolding; the sockets are defined by a metal strip folded in order to form a star-shaped part closed on itself having protuberances forming the said sockets alternating with re-entrant regions bearing against the tubular portion, the upper and lower edges of the reentrant regions in contact with the tubular portion being welded thereto by continuous or discontinuous annular weld beads.
