Abstract (en)
[origin: EP2128342A2] Fusible mechanism for the bolted joint connecting the horizontal fence, beams or railings (1) of a metallic safety barrier to the vertical support poles (2) of same that confers said joining element the capacity to be released or disengaged in a controlled manner when the intensity of the force transmitted to said joining element by an impacting vehicle reaches a pre-established threshold value. Said joining element is comprised by a bolt (3) in which a straight section or area in the rod located at a particular distance from its head has been mechanically or chemically treated to reduce its mechanical resistance capacity.
