Description

Guardrail connector {GUARD RAIL CONNECTION DEVICE}

The present invention relates to a guardrail connecting device that is inserted between the rail and the support of the guard rail to be installed on the side of the road to fix the rail to the support, more particularly light, low manufacturing cost, easy installation, vehicle collision The present invention relates to a guardrail connecting device that can be materialized to absorb a shock when it is to reduce the damage of people or vehicles.

Guardrail is a road safety facility that aims to minimize the loss of people, injuries or vehicle damage by preventing accidents that occur when a car driving on the road leaves the lane or intrudes the center line due to the driver's carelessness. Incidentally, it functions to induce the driver's line of sight to reach the destination accurately and to prevent pedestrians from crossing the road.

Guardrails are formed with a steel or column type post that is fixed to the ground by a fixed distance or other means, and a "W" type rail is used to protect all vehicles, from low-passenger cars to high-rise vans. It is fixed to the side of the road by fixing bolts and welding.

However, in the event of a vehicle crash, a tremendous shock is primarily transmitted to the rail and then delivered to the next shore. In this process, the rails and the shore are fixed, and thus there is a problem that additional damage cannot be dealt with.

Therefore, it is not only good to make the guard rails sturdy, but it is more desirable to endure the appropriate amount of impact, but to damage it while absorbing the impact on its own.

Furthermore, the connector for joining the rail to the support must have an impact buffer effect between the support and the guardrail. The conventional guardrail connector simply bends the metal plate to simply support the support between the support and the guardrail, or the space between the support and the guardrail. Since it only has a function of securing, there is almost no effect on the shock buffer.

Korean Registered Patent [10-0877527] discloses a guardrail buffer connector for roads and a method of manufacturing the same.

Korea Patent Registration [10-0877527] (Registration Date: December 30, 2008)

Accordingly, the present invention has been made to solve the problems described above, the object of the present invention is to provide a lightweight, low manufacturing cost, easy installation, to form a guardrail connecting device to absorb the impact in the event of a vehicle crash It is to provide a guardrail connecting device that can materialize, to reduce the damage to people or vehicles.

The objects of the embodiments of the present invention are not limited to the above-mentioned objects, and other objects, which are not mentioned above, will be clearly understood by those skilled in the art from the following description. .

Guard rail connecting device according to an embodiment of the present invention for achieving the object as described above, is installed between the rail and the support of the guard rail to the guard rail connecting device 1000 for fixing the rail to the support The support rail is formed in front of the guardrail connecting device 1000, is formed in a shape corresponding to one side of the support is in close contact with the support, and a predetermined region is passed through the one side of the coupling member passing through the support ( 101 is formed front portion 100; Upper and lower portions respectively formed in the upper direction and the lower direction of the guardrail connecting device 1000 and extended from the support connecting portion 100 so as to protrude rearward in a shape that gradually increases from the front portion 100 toward the rear ( 200); Left and right side portions 300 which are respectively formed in the left and right directions of the guardrail connecting device 1000 and extend from the top and bottom portions 200 to connect portions of the rear side of the top and bottom portions 200; It is formed on the front left and front right of the guardrail connecting device 1000, respectively, the upper portion and the lower portion of the left and right side portion 300 is connected to the front portion 100 and the upper and lower portion 200 is connected.
