Method of manufacturing a construction bar by crimping, and construction bar thus obtained

摘要

process for the manufacture of a bar construction (10), includes the following steps:- conduct a profiled bar (1), an insulating tip (3) which is a cross.a profile (4) has a shape capable of being taken out from body in a housing (5) of the steel bar (2).a rib (6) extending beyond the profile (4), the cross section of the insulating bar, is suitable to be embedded in a groove (7) formed on the metal bar.a first support means (50) located below the longitudinal profile, and (4) capable of coming into contact with a supporting surface (12) or the metal bar is located below the housing (5).- insert the tip of the insulating bar in the steel bar- put the insulating bar (1) and the steel bar, in order to achieve a complete connection between these two elements, so that an active part (11), forming part of the housing (5) is bent at the metal bar, the metal bar operation, as well as on the insulating bar cross reaction.at least through the groove (7) and the supporting surface (12).;bar construction thus obtained.
