Abstract

L'invention concerne un longeron d'échafaudage (20.1) constitué d'un profilé porteur métallique (21.1) en acier qui présente deux extrémités opposées (32.1, 32.2), sur lesquelles sont soudés des moyens de fixation (33.1) en métal servant assembler de manière détachable le longeron d'échafaudage (20.1) à d'autres éléments d'échafaudage (41). Un profilé de renfort en U (22.1) en tôle d'acier est soudé, par les extrémités de fixation de ses ailes latérales, sur le profilé porteur (21.1). La hauteur du profilé de renfort en U est supérieure à celle du profilé porteur, et la largeur du profilé de renfort en U est inférieure, de plus du double de l'épaisseur de paroi du profilé porteur (21.1), à la largeur du profilé porteur.
