Abstract:
(EN) A waveform beam guardrail plate and a waveform beam steel guardrail are provided. In which, the guardrail plate includes a main body (15) and two rings (16, 17) with a same structure installed axial symmetrically on an upper and a lower edges of the main body; furthermore, a transverse section of the main body has an arc shape, and the upper and lower edges of the main body of the guardrail plate are curled inwardly and helically toward a protruding direction of the main body of the guardrail plate for forming the two rings (16, 17). The waveform beam steel guardrail includes numbers of guardrail plate units (1, 11), upright posts (2) and preventing blocks (3), and the guardrail plate units (1, 11) are connected with the upright posts (2) by the preventing blocks (3).
(FR) L'invention porte sur une glissière de sécurité de forme ondulée et sur une glissière de sécurité en acier de forme ondulée dans lesquels la plaque de glissière de sécurité comprend un corps principal (15) et deux bagues (16, 17) de même structure installées en symétrie axiale sur les bords supérieur et inférieur du corps principal; de plus, la section transversale du corps principal a la forme d'un arc, et les bords supérieur et inférieur du corps principal de la plaque de la glissière de sécurité sont repliés vers l'intérieur et en hélices dans une direction de saillie du corps principal de la plaque de la glissière de sécurité afin de constituer les deux bagues (16, 17). La glissière de sécurité en acier de forme ondulée comprend un certain nombre d'éléments de plaque de glissière de sécurité (1, 11), de poteaux verticaux (2) et de blocs de prévention (3), et les unités de plaque de glissière de sécurité (1, 11) sont reliées aux poteaux verticaux (2) par les blocs de prévention (3).
