Specific embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.

As shown in Figures 1 and 2, the road guard-rail include pillar 10 that multiple spacing side by side set, located at the pillar 10 On guardrail board 20 and the protective tip 30 positioned at the end of guardrail board 20, only illustrated with pillar in figure.

The guardrail board 20 is fixed on pillar 10 by a connection piece 50.In the present embodiment, each pillar 10 is cylinder, its The below grounds such as bottom embedment soil or pitch, and vertically upwardly extend setting.Each pillar 10 is carbon steel tubing, its Opposite sides near its apical position is respectively equipped with mounting hole 11.The connector 50 is formed by metallic plate bending, and it includes solid Extend two extensions for being formed due to the fixed part 51 on pillar 10 and by the front end opposite sides outward bending of the fixed part 51 52.The connector 50 is that the one bending of strip rectangle lamellar body is formed.The fixed part 51 is by the fixtures such as screw through fixation The top of portion 51 and pillar 10 and fix.Each extension 52 is provided with fixing hole 53.

The guardrail board 20 is the corrugated of vertically concavo-convex bending extension.In the present embodiment, the guardrail board 20 is along perpendicular Nogata is to formation two convex portions 21 and the recess 22 between two convex portions 21.The cross section of each convex portion 21 and recess 22 is Isosceles trapezoid.The recess 22 is correspondingly arranged on the stator 52 of connector, and is fixed by fixtures such as screws.

Please refer to Fig. 3 and Fig. 4, the guardrail board 20 is filled out respectively respectively in the back side of the front of recess 22 and convex portion 21 If thermoplastic resin foaming body 60, the thermoplastic resin foaming body 60 can be pasted in guardrail board 20 by binding agent. The surface of the thermoplastic resin foaming body 60 being filled in the front of recess 22 and the top surface flush of convex portion 21, are filled at convex portion The surface of the thermoplastic resin foaming body 60 in 21 back sides and the bottom surface flush of recess 22.The thermoplastic resin foaming body 60 can be foamed polystyrene body or polyurethane foaming body.During specific implementation, it is embedded with the thermoplastic resin foaming body 60 Glass fabric or non-woven fabrics, make the surface of the thermoplastic resin foaming body 60 that tree line pattern is presented, and strengthen aesthetic.Should The setting of thermoplastic resin foaming body 60 in guardrail board 20, can absorb the energy of its generation in external force collision, mitigate mutual Damage.

The protective tip 30 includes the planar portions 31 of the end for being fixed on guardrail board 20 and by planar portions 31 away from shield The curled portion 32 of the end bending of breast board 20.The position of two side ends up and down of the upper and lower ends correspondence guardrail board 20 of the planar portions 31 Put and form two assembly tab 33 corresponding with the side end shape of guardrail board 20 respectively, each assembly tab 33 is worn by fixtures such as screws It is fixed located at the side end of assembly tab 33 and guardrail board 20.In the present embodiment, the correspondence guardrail board 20 of the planar portions 31 Recess 22 is provided with the fixed block 35 being contained in recess 22, and each fixed block 35 is fixed on the recessed of guardrail board 20 by modes such as welding In portion 22.The curled portion 32 is reciprocally bending to the dorsal part direction of guardrail board 20 from the end away from fixed block 35 of planar portions 31 If being curled into dried layer tubular.In the present embodiment, the curled portion 32 is included from the end of planar portions to the dorsal part direction edge of guardrail board 20 Clockwise the outer drum layer that is curled into and by outer drum layer end in the inner drum layer being curled into the counterclockwise direction in outer drum layer.Specifically During implementation, the number of plies of the curled portion is not limited by the present embodiment, and it can be two-layer, or three layers or multilayer.

During specific implementation, the guardrail board 20 and protective tip 30 are elastic metallic material and are made, concretely roll forming steel Plate or hot-dip galvanized steel sheet etc..The structure of the guardrail board 20 is not limited to the case for this embodiment, and it can be to include along longitudinal concavo-convex The recess 22 of three convex portions 21 and two for extending, or two convex portions 21 and a recess 22 are bent, can also be the recessed of other quantity Portion 22 and convex portion 21, the number of the fixed block 35 of the structure of its protective tip 30 are changed also according to the structure correspondence of guardrail board 20. The road guard-rail is set in it sharp corner bag of the end of guardrail board 20 by protective tip 30, and together with guardrail board 20 Elastomer is formed, the energy produced during Vehicular impact can be absorbed, mitigate occupant's injury degree, reduced to road guard-rail Damage, and then play a part of protection.

Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
