Abstract

The present invention relates to a guardrail reinforcement structure comprising one and more wire ropes, which are formed in the longitudinal direction of a guardrail plate on one side of the guardrail plate; and a binding unit, which firmly fixes the wire ropes on the guardrail plate. Disclosed is the guardrail reinforcement structure having wire ropes firmly fixed on one side of the guardrail plate installed in a support. Therefore, the support, the guardrail plate, and the wire ropes simultaneously mitigate impact occurring when a vehicle collides with the guardrail plate. Therefore, the impact can be effectively mitigated. Also, damage to the guardrail plate can be minimized, so costs needed to maintain the guardrail can be reduced. In addition, when a vehicle collides with the guardrail plate, an impact mitigating unit prevents a wire rope at a collision point from being pulled and being stretched by the impact. Therefore, a possible secondary accident by a stretched wire rope causing a vehicle to depart from the road can be prevented. Also, safety can be enhanced. In addition, a fluorescent tube coated on the wire ropes secures high visibility at day and night. Therefore, a guardrail collision accident of a vehicle, which is caused by low visibility, can be prevented.

Description

[0001] Guardrail reinforcement structure [

The present invention relates to a reinforcing structure of a guard rail, more particularly, to a structure in which a wire rope is firmly installed on one side of a guardrail plate provided on a support, The guard rail plate and the wire rope can be eliminated at the same time, so that the impact can be effectively solved (alleviated), and the damage of the guardrail plate can be minimized, thereby reducing the cost of maintenance and management of the guardrail To a reinforcing structure of a guardrail.

Generally, the guard rail installed on the road side is installed for the purpose of preventing a vehicle from falling off the road due to an unexpected accident on the road and causing a secondary accident that the vehicle falls or overturns. If the strength of the shear strength suffers in the event of a vehicle collision, the guard rail is easily damaged and the road is released. If the shear strength of the guardrail is strengthened, There was a risk of a secondary accident with the side or behind the vehicle, because the car could be thrown out due to the rebound shock.

Accordingly, the Ministry of Construction and Transportation (MOCT) has been guiding the installation and management of road safety facilities through the vehicle crash test for guard rails since July 2002, thereby preventing the vehicle from being separated from the road and suggesting a standard to prevent passenger cars from being thrown out. To be used.

However, the conventional guard rails installed on the roadside include a pillar installed at regular intervals on the ground, and a guardrail plate installed on the pillar. The guardrail plate, which is usually formed of a flat metal plate, The detachment of the pin connecting the guard rail plate to the plate and the weak shear strength of the guard rail plate are easily broken even when the vehicle collides with the vehicle and the post (POST) is also transmitted. As described above, It is difficult to expect the guard rail function to prevent secondary accident of overturning and falling.

Therefore, in order to solve the above-described problem of the guard rail, there is proposed a registra- tion utility model No. 20-0432896 (a guardrail post reinforcement structure using a wire cable) and a registra- tion utility model No. 20-0394517 Guard rails) have been proposed to reinforce the guard rails using wire ropes.

However, the above-mentioned Registration Utility Model No. 20-0432896 (guardrail reinforcement structure using a wire cable) has a structure in which the wire rope is spaced apart from the rear of the guardrail plate, so that a primary collision with the guardrail plate occurs in the event of a vehicle collision It is difficult to effectively mitigate the impact in comparison with the structure in which the guard rail plywood wire rope mitigates the impact together, and the guard rail plate is easily damaged due to the structure in which the guard rail plate is easily broken. There is a disadvantage in that the cost of maintenance and repair such as repair and replacement is high.

In addition, in the above-mentioned registered utility model publication No. 20-0394517 (two-stage shock-absorbing type guardrail), the wire rope is spaced apart from the upper portion of the guard rail, A large-sized vehicle having a large body when the vehicle is separated from the road may be able to cope with a certain portion of the wire rope, but in the case of a small-sized vehicle having a low body, the wire rope does not collide with the vehicle body or the bumper, It is more dangerous to collide with the side window glass.

Furthermore, a wire rope such as a registered utility model publication No. 20-0432896 (guardrail reinforcement structure using a wire cable) and a registration machine model No. 20-0394517 (two-stage shockproof type guardrail) The structure of the structure reinforcing the wire rope has proposed a structure for mitigating the impact by simply installing the wire rope. However, when a vehicle traveling at high speed collides with the wire rope, The wire rope is pulled and stretched. As a result, the vehicle easily deviates from the road so that a secondary accident frequently occurs.

Therefore, development of a guardrail capable of solving the above problems is urgently required.
