A GUARD RAIL FOR ABSORBING IMPACTION AND AN APPARATUS FOR ABSORBING IMPACT ENERGY USED IN THAT APPARATUS

摘要

The present invention includes a plurality of supports and is provided on the guard rail consists of tensile steel is connected between the support used for impact absorption by a bellows member which effectively absorbs the impact energy of the vehicle collision guard rail device, and this is installed at a predetermined interval relates to a shock energy absorber is mounted to at least one end of each support and tension the steel material comprises an energy conversion means for converting a pulling force caused by the external force acting on the tension steel material to plastic deformation. Energy converting means has a predetermined length both end surfaces are connected to the tension of steel through the housing, a hole formed in a ball fastened to be fixed to the blind cylindrical shape and the end face, the holes of the side end portions is formed in the other end face, the support is the inner surface of the housing in accordance with the mobile plate, the first and / or provided between the plate and the housing to the second member it includes a bellows. If the impact can the energy absorber to absorb the vehicle collision impact energy effectively by providing a suitable distance to the guard rails and This sikimyeo reduce the accident's injury, replace only the wire at the time of repair of the guardrail that section configured as described above since thereby reducing costs and time. Further, the impact energy absorption device of the present invention can be obtained also in the driver's field of vision, so the connection in the tensioned steel wire.
