Title (EN) BREAKAWAY SUPPORT POST FOR HIGHWAY GUARDRAIL END TREATMENTS
(FR) POTEAU DE SUPPORT A MECANISME DE RUPTURE POUR EXTREMITES DE RAIL DE GLISSIERE DE SECURITE D'AUTOROUTE
Abstract:
(EN) A breakaway support post (130) is provided for a highway guardrail system (120) to enhance the safety of a vehicle impacting with either the rail face of the associated guardrail or one end of the guardrail facing oncoming traffic. For some applications, the breakaway support post (130) may be formed from a steel I-beam with one or more elongated slots formed intermediate the ends of the steel I-beam. The slots are preferably formed in the flanges of the I-beam which are in turn aligned generally parallel with the associated guardrail. For other applications, a breakaway support post may have an upper (142) and a lower (144) portion with a rotatable coupling (140) assembly disposed therebetween. A shear pin (156) or other releasing mechanism is preferably provided to maintain the upper and lower portions generally aligned with each other prior to the impact of a vehicle with one end of the associated guardrail.
(FR) Ce poteau de support à mécanisme de rupture (130) pour système de glissière de sécurité d'autoroute (120) a pour but d'accroître la sécurité des passagers d'un véhicule entrant en collision avec, soit la face d'une rail de la glissière, soit l'une de ses extrémités coté trafic. Dans certaines réalisations, ce poteau (130) peut être fabriqué à partir d'une poutre d'acier en forme de I et comprendre une ou plusieurs fentes situées entre les extrémités de la poutre. Ces fentes se trouvent, de préférence, dans les ailes de la poutre en forme de I, lesquelles sont, d'ordinaire, parallèles au rail de la glissière de sécurité associée. Dans le cas d'autres applications, le poteau de support à mécanisme de rupture peut comporter une partie supérieure (142) et une partie inférieure (144) entre lesquelles se trouve un ensemble de couplage rotatif (140). Le système comporte, de préférence, une goupille de cisaillement (156) ou tout autre mécanisme de dégagement servant à maintenir dans l'alignement les parties supérieure et inférieure avant qu'un véhicule n'entre en collision avec l'une des extrémités du rail de la glissière de sécurité associée.
