And seriously undermined the occupant's safety.

In order to solve this problem, a method of placing a bracket having a complicated shape between the support and the guardrail plate, like a rubber buffer, has been proposed. However, the complexity of the shape causes an increase in the unit cost. Due to the looseness of the fastening part, it is difficult to maintain the rigidity of the guardrail at the initial installation level and there is a concern that the debris separated from the guardrail due to the tearing of the bracket may violate the safety of the vehicle occupant.

In addition, in recent years, a method of using a guard rail plate having a different cross sectional ratio or having a different thickness as a guard rail plate and a lower guard rail plate has been attempted. However, in this case, the effect of shock absorption is Although it can be expected, it causes a sharp increase in manufacturing costs and is very difficult to apply to existing products.

The present invention has been made to solve the problems of the prior art, in the fastening device installed between the guard rail plate and the guard rail support, the impact applied during the guardrail collision of the vehicle by having the fastening device has a constant elastic force The purpose of this invention is to provide a shock absorbing rigid guardrail device having a structure that can easily absorb and disperse the vehicle in several stages, minimize the damage to the vehicle, ensure the safety of the occupants, and return the vehicle to the original driving direction. .

Another object of the present invention is to provide a shock absorbing rigid guardrail device to prevent overturning of the support by reinforcing the landfill by inserting the support in the socket having a border when the installation of the support, and to reinforce the impact strength of the guard rail plate. have.
