A kind of road guard-rail, including multiple spacing side by side set pillar, the guardrail board on the pillar and be located at
The protective tip of guardrail board end, the guardrail board and protective tip are manufactured by elastic metallic material, and the guardrail board is along perpendicular
The corrugated that Nogata is arranged alternately to recess and convex portion, the protective tip include the planar portions of the end for being fixed on guardrail board and
The curled portion bent by the end away from guardrail board of planar portions, the curled portion is away from guardrail board by planar portions
If end reciprocally bending is curled into dried layer tubular to the dorsal part direction of guardrail board.
Preferred scheme is that the end position of both sides up and down of the upper and lower ends correspondence guardrail board of the planar portions is formed and protected respectively
Corresponding two assembly tab of side end shape of breast board, each assembly tab by fixture be arranged in assembly tab and guardrail board side end and
It is fixed.
Preferred scheme is that the recess of the planar portions correspondence guardrail board is provided with the fixed block being contained in recess, each fixation
Block welding is fixed in the recess of guardrail board.
Preferred scheme is, the curled portion include from the end of planar portions to guardrail board dorsal part direction along being curled into clockwise
Outer drum layer and by outer drum layer end in the inner drum layer being curled into the counterclockwise direction in outer drum layer.
Preferred scheme is that each convex portion that the guardrail board is vertically formed and the cross section of recess are isosceles ladder
Shape.
Preferred scheme is that the guardrail board is fixed on pillar by a connection piece.
Preferred scheme is that the connector is formed by the one bending of strip rectangle lamellar body, and it includes being fixed on pillar
Fixed part and two extensions for being formed are extended by the front end opposite sides outward bending of the fixed part, the guardrail board is fixed on
On extension.
Preferred scheme is that multiple peep holes are also interval with the guardrail board.
Beneficial effects of the present invention are：
Road guard-rail of the invention is set in it sharp corner bag of the end of guardrail board by protective tip, and with shield
Breast board forms elastomer together, can absorb the energy produced during Vehicular impact, mitigates occupant's injury degree, reduces to road
The damage of road guard rail, and then play a part of protection.
