Abstract

L'invention concerne un dispositif (1) de retenue de véhicules léger et lourd le long d'une voie de circulation, le dispositif comportant une barrière de sécurité (2) à lisses (7) et un moyen de retenue (3) haut rapporté, la barrière de sécurité comportant des poteaux (5) et des écarteurs (6), les lisses étant fixées sur les écarteurs, le moyen de retenue haut comportant des tiges (8) sur lesquelles sont accrochés par des moyens de fixation (10) des éléments de retenue (9) longitudinaux, les tiges (8) étant introduites dans les poteaux et pouvant y coulisser. Selon l'invention, les éléments de retenue longitudinaux (9) sont fixés rigidement sur les tiges (8) de telle manière qu'en cas de choc avec un véhicule, les tiges (8) restent solidaires des éléments de retenue (9) et la tige (8) est un profilé métallique en C droit dont la résistance est telle qu'en cas de choc avec un véhicule, la tige (8) puisse plier sous l'action, d'une part, vers le bas de la tige, du pliage du poteau de la barrière de sécurité et, d'autre part, vers le haut de la tige, de l'effet de tirage longitudinal des éléments de retenue longitudinaux, ledit pliage de la tige et ladite fixation de la tige permettant que la déformation finale avant-arrière du dispositif de retenue corresponde sensiblement au pliage du poteau de la barrière de sécurité.

The invention relates to a device (1) for retaining light and heavy vehicles along a traffic lane, the device comprising a safety barrier (2) with rails (7) and an attachment retaining means (3). , the safety barrier comprising posts (5) and spacers (6), the rails being fixed on the spacers, the high retaining means comprising rods (8) on which are hung by fastening means (10) longitudinal retaining elements (9), the rods (8) being introduced into the posts and being able to slide therein. According to the invention, the longitudinal retaining elements (9) are fixed rigidly on the rods (8) in such a way that, in the event of impact with a vehicle, the rods (8) remain integral with the retaining elements (9) and the rod (8) is a straight C-shaped metal section whose resistance is such that, in the event of impact with a vehicle, the rod (8) can bend under the action, on the one hand, towards the bottom of the rod , folding the post of the safety barrier and, on the other hand, towards the top of the rod, the longitudinal pulling effect of the longitudinal retaining elements, said folding of the rod and said fixation of the rod allowing that the final deformation of the front-rear restraint substantially corresponds to the folding of the post of the safety barrier.
