<p>The present invention relates to a road guardrail and, more specifically, relates to a road guardrail which effectively absorbs shock to a vehicle as the wide surface of a continuously curved corrugated rail fence is installed to face upwards, and which enables drivers to enjoy the surrounding scenery while driving the vehicle without hiding the surrounding scenery. According to the present invention, the road guardrail includes the rail fences (20) mounted on a support frame (10) built on the edge of a road using a bolt (11). A rail fence (20) is made of a continuously curved corrugated steel plate (21). The rail fence (20) is horizontally mounted on the support frame (10) to face upwards with its wide surface, and is fixated by a triangular frame (30). The vertical surface (31) of the triangular frame (30) is fixated to the support frame (10) by the bolt (11). The horizontal surface (32) of the triangular frame (30) is fixated to the rail fence (20) by the bolt (11). A fold line (33a) on a joint surface (33) between the vertical surface (31) and the horizontal surface (32) makes the joint surface (33) be folded to absorb shock upon collision of a vehicle.</p> |
