Abstract
Description
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.
It is an object of the present invention to provide a structure in which a wire rope is firmly installed on one side of a guardrail plate provided on a support, The damage to the guard rail plate and the wire rope can be solved at the same time, so that the impact can be effectively solved (alleviated), and the damage of the guard rail plate can be minimized, And a reinforcing structure of the guard rail.
In addition, since the impact relaxation means prevents the wire rope at the collision point from being stretched due to the impact when the vehicle collides with the guardrail plate, the wire rope is extended to prevent a secondary accident that may occur when the vehicle leaves the road And a reinforcing structure of a guardrail that can enhance safety.
Another object of the present invention is to provide a guardrail reinforcement structure capable of preventing a collision of a guardrail of a vehicle due to low visibility by securing a high visibility at night or night owing to a fluorescent tube covered with a wire rope.
According to another aspect of the present invention, there is provided a guardrail reinforcement structure including: a guardrail plate having at least one wire rope formed on a surface of a guardrail plate in a longitudinal direction of the guardrail plate; And a binding means for firmly binding and fixing to the guardrail plate,
It is possible to minimize the damage of the guard rail plate by mitigating the impact caused by the collision due to the collision of the guard rail plate when the vehicle collides with the wire, thereby preventing the vehicle from being detached due to breakage of the guard rail plate. do.
The U-bolts are positioned at both ends of the U-bolt so that the wire rope is positioned inside the U- And a binding nut for firmly fixing a position of the wire rope and guiding the wire rope positioned inside the U bolt to be firmly fixed, wherein the binding means is installed at a constant interval.
Further, the present invention is characterized by further comprising shock absorbing means for effectively absorbing impact from the wire rope when the vehicle collides with the guard rail plate, thereby easily preventing the vehicle from departing.
The U-bolts may include a U-bolt and a U-bolt. The U-bolt may be fixed to the wire rope. The U- And a second fixture located on the other side of the U-bolt,
When both sides of the wire rope are pulled on the basis of a point of collision due to an impact at the time of a vehicle collision on the guardrail plate, the fixed body positioned on the wire rope is brought into contact with the U bolt, So that the wire rope at the point of collision due to the impact is extended, thereby preventing the vehicle from being detached.
Further, a wire sleeve (clip) is used as the fixing body.
In addition, a fluorescent tube containing a fluorescent pigment is coated on the outer circumferential surface of the wire rope so that visibility can be easily ensured at night or night.
And connecting means for interconnecting the end of the wire rope of the reinforcing structure of the guard rail and the end of the wire rope of the reinforcing structure of the other guardrail,
The connecting means includes a first wire sleeve for bending an end of the wire rope of the reinforcing structure of the guard rail so as to be bent and fixed to the wire rope so as to form a ring at the end of the wire rope, A second wire sleeve for bending an end of the wire rope of the structure so as to be bent and fixed on the wire rope so as to form a ring at the end of the wire rope and a ring formed on the wire rope end of the reinforcing structure of the guard rail And a turn buckle for interconnecting the rings formed at ends of the wire ropes of the reinforcing structure of the other guard rails.
As described above, according to the reinforcing structure of the guard rail according to the present invention, the wire rope is firmly installed on one surface of the guardrail plate provided on the support, so that the shock generated when the vehicle collides with the guardrail plate 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 There is an effect.
In addition, since the impact relaxation means prevents the wire rope at the collision point from being stretched due to the impact when the vehicle collides with the guardrail plate, the wire rope is extended to prevent a secondary accident that may occur when the vehicle leaves the road It has an effect of enhancing safety.
In addition, since the fluorescent tube covered with the wire rope secures high visibility in day and night, it is possible to prevent the guardrail collision of the vehicle due to low visibility in advance.
