Description

Guardrail protector

The present invention relates to a guardrail protection device, and more particularly, it is possible to increase the life of the guardrail installed on the road, and to protect the driver and the vehicle as well as the guardrail by absorbing shocks when the vehicle collides with the guardrail. The present invention relates to a guardrail protection device.

Generally, guardrails are a road safety facility that is installed on the outside of a road or bridge, or in the center of a roadway to prevent cars driving on the road from leaving lanes or invading the center line.

The guard rail prevents accidents to minimize personal injury or vehicle damage, and prevents pedestrians from crossing the road. In addition, it helps to secure the driver's vision by blocking the headlights of vehicles coming from the other side at night, and reflects the light emitted from the headlights of the vehicles driving at night so that the driver can easily recognize the curvature and the boundary of the road. To help.

The guardrail is composed of pillars embedded in the ground at regular intervals and fence panels coupled laterally to the pillars. Pillars and fence panels are mainly made of steel. Fence panels generally have curvature for structural strength reinforcement.

The guard rail is exposed to rain, snow, and vehicle exhaust, and when used for a long time, dust accumulates or various foreign substances adhere to the surface, and its surface is contaminated, resulting in surface corrosion. Contaminated guardrails also hurt the beauty of the streets. In consideration of these problems, a method of painting the guardrail can be considered, but this also has a problem that the paint is peeled off for a long time and requires continuous maintenance, resulting in the cost of frequent maintenance.

Hereinafter, with reference to the accompanying drawings, it will be described in detail with respect to the guardrail protection device according to the present invention.

In describing the present invention, the sizes and shapes of the components shown in the drawings may be exaggerated or simplified for clarity and convenience of explanation. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. These terms are to be construed in accordance with the meaning and concept consistent with the technical idea of the present invention based on the contents throughout the present specification.

1 and 2 are for explaining the guardrail protection device according to an embodiment of the present invention.

1 and 2, the guardrail protection device 100 according to an embodiment of the present invention is coupled to the fence panel 11 of the guardrail 10 to protect the fence panel. The guardrail protection device 100 includes a front cover 110 covering the front surface of the fence panel 11 and a buffer member 120 disposed between the fence panel 11 and the front cover 110.

The front cover 110 is provided at the cover body 111 to cover the front of the fence panel 11, the upper engaging portion 112 provided at the upper end of the cover body 111, the lower end of the cover body 111 It includes a lower locking portion 113. The front cover 110 may be made of various materials having rigidity such as plastic or metal.

The cover body 111 is provided with a flat display surface 114 disposed perpendicular to the ground. On the display surface 114, a traffic guidance symbol 115 for a driver is displayed. Since the guard rail 10 is disposed at the eye level of the driver who drives the vehicle, the guard rail 10 is a visible part of the driver on the road. Therefore, when the traffic guide symbol 115 is displayed on the front cover 110 coupled to the guard rail 10, it is easy for the driver to check. In addition to the traffic guide symbol 115, the display surface 114 may display road information, advertisements, and various patterns or images for improving aesthetics of the road.

The upper locking portion 112 is bent downward from the upper end of the cover body 111 so as to be caught on the upper end of the fence panel 11, the lower locking portion 113 is the lower portion of the fence panel 11 It is provided bent in the upper direction from the lower end of the cover body 111 so as to be caught on the end. The upper cover 112 is caught by the upper end of the fence panel 11 and the lower stop 113 is caught by the lower end of the fence panel 11 so that the front cover 110 can be firmly fixed to the fence panel 11. Can be.
