Abstract

Disclosed is a road guardrail which comprises guardrail columns (1) and a guardrail body (2). The guardrail body (2) is mounted on the guardrail columns (1). The road guardrail is characterized in that the guardrail body (2) comprises a guard board (3) made of elastic plastic, a wave-shaped steel board (4) and a plurality of elastic components which are arranged repeatedly and in parallel. The guard board (3) attaches tightly onto the wave-shaped steel board (4) which is tightly fixed with one faces of the plurality of the elastic components, the other faces of the plurality of the elastic components are fixed on the guardrail columns (1) in a tight attaching mode, and upper covering boards and lower covering boards are arranged on the top faces and the bottom faces of the elastic components respectively. According to the road guardrail, the multi-layer buffer of the guard board (3), the wave-shaped steel board (4) and the elastic components are utilized, so that a large quantity of impact energy can be absorbed, and the guardrail, vehicles and the human safety are protected effectively. The road guardrail has the advantages of being ingenious in design, convenient to mount and wide in applicable range.

Description

technical field [0001] The invention relates to a road safety protection device, in particular to a buffered road guardrail. Background technique [0002] The road guardrail is set on both sides of the road and can also be used between the lanes. It not only has the function of isolating the lanes, but also plays the role of buffer protection when hit by vehicles. Existing a kind of application number is 200910014702.4 and the Chinese invention patent application titled "Highway Guardrail" discloses a kind of road safety protection device, particularly relates to a kind of highway guardrail. The road guardrail includes a guardrail body and a guardrail post with a guardrail cap, and is characterized in that: the guardrail body is provided with a reinforcing hole, and the reinforcing hole is filled with reinforcing ribs; the guardrail post is hollow cylindrical, and the guardrail post cap It is a round rainproof cap, and the guardrail post cap is installed on the top of the g...
