If it is necessary to adjust the mounting position of the fixing bracket, with the bolt part 42 pushed into the bottom side of the lip channel (the upper side in Fig. 22), shift the position of the lip channel 10 and hook it. Change the notch to lock the stop 41 (8th step). Finally, the nut 60 is joined to the position indicated by the solid line in FIG. 22 and tightened (ninth step (final fastening step)).
  • the order of the first step to the ninth step can be changed as appropriate according to the working mode, etc., which is not limited to this.
  • the fifth step and the sixth step may be arranged immediately after the seventh step.

Abstract

La présente invention concerne un procédé pour installer un élément en acier selon lequel un élément de fixation métallique n'est pas susceptible d'être déplacé par rapport à un canal à rebord en acier, même si une grande force externe est appliquée sur l'élément de fixation. Le procédé pour installer un élément en acier permet de relier un canal à rebord en acier (10) à une pièce angulaire en acier (50) en utilisant un élément de fixation métallique (40). Le canal à rebord en acier (10) présente, dans un bord d'extrémité de rebord, des découpes en dents de scie et un trou de boulon est ménagé dans la pièce angulaire en acier (50). L'élément de fixation métallique (40) est constitué d'une partie d'engagement (41) conçue pour raccorder l'élément de fixation et les découpes en dents de scie et d'une partie de boulon (42) qui passe à travers le trou de boulon (53). La partie d'engagement (41) s'engage avec les découpes en dents de scie du canal à rebord en acier (10) et la partie de boulon (42) passe à travers le trou de boulon dans la pièce angulaire en acier (50) et est serrée. Le canal à rebord en acier (10) est ainsi relié à la pièce angulaire en acier (50).
