This dismantling is then carried out in each additional scaffolding bay.
  • the railing device 10 is designed in such a way that it is present as a permanent railing device during the service life of the scaffolding 50 and thus the safety standards are guaranteed during the entire service life. At the same time, due to the frame-like overall construction of the railing device 10 in conjunction with its connecting devices (20, 22, 24, 26), the railing device 10 is designed as a component stiffening the entire frame 50, so that no additional diagonals or railing bars have to be mounted.

Abstract

L'invention concerne un dispositif de garde-corps (10) destiné à un échafaudage (50). Ledit échafaudage est doté de niveaux d'échafaudage (54) comprenant des arbres verticaux (58) espacés dans le sens de la largeur (B), des traverses (60) reliés aux arbres verticaux (58) dans la direction transversale (Q), des revêtements reliés aux traverses (60) dans le sens de la largeur (B). Le dispositif de garde-corps (10) est réalisé sous la forme d'un dispositif de garde-corps principal qui est installé à partir d'un niveau d'échafaudage inférieur existant (54) pour un niveau d'échafaudage supérieur devant être installé au-dessus et qui forme ensuite une protection latérale pour le niveau d'échafaudage supérieur. Un arbre de garde-corps de droite (16) comporte, dans sa zone d'extrémité inférieure, un premier dispositif de raccordement (20) et un second dispositif de raccordement (22) disposé à un espacement au dessus du premier dispositif de raccordement (20) ; un arbre de garde-corps gauche (18) comporte, dans sa zone d'extrémité inférieure, un troisième dispositif de raccordement (24) et un quatrième dispositif de raccordement (26) disposé à un espacement au-dessus du troisième dispositif de raccordement (24), et le troisième dispositif de raccordement (24) comporte une troisième et une quatrième unité de saillie, dont chacune fait saillie au-delà de la région d'extrémité libre dans la direction de la largeur (B) et qui entrent en contact avec le contour extérieur d'un arbre vertical (58) à l'intérieur lorsqu'il est installé, c'est-à-dire la distance interne de jeu dans la direction transversale (Q) de la troisième et de la quatrième unité de saillie correspond sensiblement au diamètre extérieur de l'arbre vertical (58), la troisième unité de saillie étant conçue pour être mobile/rotative d'une position fixe à une position libérée et vice versa.
