The guard rail bar is assembled with bolts and nuts on the support.
However, the conventional guardrail has a simple shape, which can be easily broken due to collision of the vehicle, which may make it difficult to properly exhibit the characteristics of protecting the vehicle or alleviating the collision.
An object of the present invention is to provide a guardrail assembly reinforced with a shock absorbing structure capable of effectively absorbing an impact applied at the time of a vehicle collision and minimizing deformation or breakage of the guard rail.
Further, it is possible to provide a guardrail assembly reinforced with a shock absorbing structure capable of maximizing impact buffering effect irrespective of the point of collision of a vehicle and enhancing visibility irrespective of the traveling direction of the vehicle to prevent an accident in advance .
A guardrail assembly reinforced with a shock absorbing structure according to the present invention comprises: a plurality of strut members embedded in the ground or fixed on the ground so as to be spaced apart from each other at a predetermined interval; A guard rail provided so as to traverse the plurality of strut members at a front surface of the plurality of strut members and provided with a plurality of spaced apart upper and lower strut members; And an impact absorbing member provided corresponding to the shape of the outer circumferential surface of the strut member and interposed between the strut member and the guard rail.
Here, the strut member is provided in the shape of a triangular column so that a corner portion thereof is directed to the guard rail, and a portion of the impact absorbing member, which is coupled with the strut member, corresponds to the corner shape of the strut member, It is preferable to be formed concavely.
Meanwhile, the guardrail assembly with the shock-absorbing structure reinforced according to the present invention includes a plurality of reinforcing cushioning members installed in the width direction of the guard rail across the plurality of guard rails and spaced apart from each other at regular intervals .
The reinforcement cushion member may include a fastening plate coupled to the guard rail and a fastening plate integrally bent from the fastening plate so as to protrude through a space spaced between the plurality of guard rails, It is preferable that the interspacing buffer be inclined gradually toward the other side.
According to the present invention, it is possible to provide a guard rail assembly having an impact absorbing structure reinforced that can effectively absorb shock applied when a vehicle is in a collision and minimize deformation or breakage of the guard rail.
Further, it is possible to provide a guardrail assembly reinforced with a shock absorbing structure capable of maximizing impact buffering effect irrespective of the point of collision of a vehicle and enhancing visibility irrespective of the traveling direction of the vehicle to prevent an accident in advance can do.
