Description

Road guard rail coupling structure between rails {COUPLING STRUCTURE FOR RAIL AND RAIL OF GUARD RAIL USING ROAD}

The present invention relates to a coupling structure between rails of a road guard rail, and more specifically, to reduce the impact energy generated when a vehicle crashes and to reinforce the support force between the rail and the rail coupling by reinforcing the existing or new guard rail. By reinforcing the buffering and supporting structure between the rail end and the rail end, which are jointed while being coupled to the support rail of the guardrail, only the coupling structure added between the rails is installed in the installation state of the new guardrail as well as the existing support. The present invention relates to a coupling structure between rails of a road guard rail that provides a buffer coupling structure corresponding to simplicity and impact.

Guard rails installed on roads refer to protective measures installed on both sides of the road for the safety of road traffic, or a median divider installed in the middle of the road. Especially, it is installed to prevent cars from falling out of the road on mountain roads or roads with many curves. , In cities, it is installed at the boundary between sidewalks and roadways to protect pedestrians and to minimize injury and vehicle damage to occupants of accident vehicles. Therefore, the guardrail must have a structural rigidity enough to withstand when a traveling vehicle collides with the rail, and also must have a shock absorbing ability for the safety of the occupants.

Until now, many technologies have emerged regarding guard rails that have the function of absorbing impact energy due to collision. For example, fastening a rail in which a plate-like plate member is bent in two or three stages on a vertically installed post. It is a guard rail that is installed by combining and fixing with members.

However, the guardrail structure as described above is not only not beautiful because the rail is made of only a metal plate, and the rail with a large plate member attached to it is installed between the driveway and the sidewalk, blocking the view and preventing the vehicle from colliding. There is a problem that damage to an accident vehicle and injuries to the occupants cannot be reduced because the rails with bent plate members cannot absorb all the shocks, and if the shocks are large, the shocks received by the rails are transmitted to the support as they are.

Therefore, the applicant of the present invention basically has structural stiffness enough to withstand the impact when a traveling vehicle or heavy object collides with the guard rail, and is installed in the jointed portion of the rail and the rail to effectively absorb the impact. The development of a guardrail that can cushion and demonstrate a solid bond between rails as well as a beautiful exterior has been developed.
