Abstract
The present invention provides a guardrail structure which is installed at the center of a road or on a side of a road to prevent the vehicle from being separated. A polygonal reinforcement is provided between a pair of guardrails parallel to each other to reinforce the strength of the guardrail and collide with the vehicle. In order to improve the safety of the city, the guardrail structure according to the present invention comprises: a plurality of struts vertically installed at regular intervals on the road; A first guard rail and a second guard rail which are fixedly coupled to both sides of the support part and installed side by side along a road while being spaced apart from each other in a lateral direction; It is installed in the space between the first guard rail and the second guard rail, characterized in that it comprises a reinforcing member having a polygonal pillar shape.
Description
The present invention relates to a guardrail structure, and more particularly, in a guardrail structure installed at a center of a road or a side of a road to prevent the vehicle from being separated, a reinforcing structure having a polygonal structure is disposed between a pair of guardrails parallel to each other. Therefore, the present invention relates to a guardrail structure capable of reinforcing the strength of a guardrail and improving safety in a vehicle crash.
In general, the guardrail structure is installed along the center line of the road, that is, along the yellow solid line that defines the driving width of the road. It prevents large-scale collisions in advance or is installed on the edge of roads or bridges to prevent departure of driving vehicles.
Typically, the guardrail structure includes a plurality of struts vertically installed at regular intervals along a center or side of the road, and a W-shaped bumpy guardrail horizontally connecting the struts. In the case of the guardrail structure on the side of the road, the guardrail is composed of a single body, and in the case of the guardrail structure installed in the center of the road, a plurality of guardrails are generally arranged side by side at a predetermined distance from each other in the lateral direction.
However, the conventional guardrail structure as described above remains empty space between the support portion and the support portion, so if the vehicle collides with this portion, the guardrail is severely deformed and the vehicle penetrates the guardrail and moves to the opposite lane for large size. An accident may occur or a problem may occur in which the vehicle's protective function is not properly performed.
In order to solve this problem, Korean Patent Registration No. 10-0969810 (registered on July 5, 2010) discloses a vehicle safety protection measure (guard rail structure) in which a truss structure buffer part is formed in a space between a support part and a support part. It is.
However, the guardrail structure of the registered patent has a limit in strength improvement because the flat buffer bar is simply connected to the space between the support part and the support part in a zigzag form to form a truss structure. There is a problem that can cause a fatal damage to the occupant by digging into the vehicle as it is built.
The present invention is to solve the above problems, the object of the present invention is to provide a significantly improved strength compared to the conventional guardrail structure, and to further improve safety by absorbing the shock while crushing during a strong impact. To provide a guardrail structure.
The present invention for achieving the above object, and a plurality of struts vertically installed on the road at regular intervals; A first guard rail and a second guard rail which are fixedly coupled to both sides of the support part and installed side by side along a road while being spaced apart from each other in a lateral direction; Provided in the space between the first guard rail and the second guard rail, provides a guard rail structure comprising a reinforcing member having a polygonal pillar shape.
As described above, according to the present invention, since a reinforcing member having a polygonal honeycomb shape is installed in the space between the supporting portion and the supporting portion, the strength of the guard rail is greatly improved, and when a large impact is applied, the reinforcing member As the shock absorbs the shock, the vehicle protection function can be further improved.
