Abstract

588501 Disclosed is a bolted joint mechanism located between a horizontal fence and vertical support poles of a metallic traffic or vehicle safety barrier intended to contain vehicle lateral impacts at margins and median strips of roads. The bolted joints connecting a fence to a pole have at least one characteristic that confers a controlled fusible behaviour when impacted by a colliding vehicle, which enables the bolted joints to be uncoupled or released when the level of the force transmitted to the bolted joints by the vehicle impacting the metallic safety barrier reaches a pre-established value wherein a bolt of the bolted joints between the fence, and the pole are characterized in having a rod connected to a bolt head. A section or area along the length of the rod of the bolt has a lower mechanical resistance obtained by applying a mechanical, thermal or chemical treatment to that particular section or area of the rod of the bolt than a remaining section or area of the rod of the bolt. The rod of the bolt has at a given distance from the bolt head a furrow-like and/or cylindrical section or area with a diameter smaller than the diameter of the rod, or the rod of the bolt have at a given distance from the bolt head, one or several notches that are perpendicular to the rod or slightly tilted from the perpendicular axis of the rod wherein each notch is located along a single section of said rod.
