Abstract
The utility model relates to a high strength tubular guard rail which is provided with a stretch-proof strap and a tube body fixed on the stretch-proof strap, wherein the tube body is made by adopting reinforcing modified PVC material, and the top part of the tube body is provided with a shock resistance strap. The section of the stretch-proof strap is shaped as an M with an arc depression at the middle, the section of the tube body is shaped as an irregular cycle, and the section of the shock resistance strap is shaped as an arc. The stretch-proof strap and the shock resistance strap adopt hot-melt coated metal strips or hot-melt coated fibre glass and carbon fibre or other materials which can increase the tensile strength. Compared with the prior art, the utility model adopts the novel irregular cycle which causes the tubular guard rail to have a certain distortion under the load so as to reach the most energy absorption, and has the advantages of best anticollision safety performance, environment protection, low cost, long service life, and the like.
Description
Technical field:
The utility model relates to the guardrail board that a kind of highway is used, and the particularly a kind of shock resistance band of reinforcement, high strength tubulose guardrail of stretch-proof band of having is mainly used in the divided shielding of road driveway.
Background technology:
Present highway protecting plate adopts galvanized steel plain sheet usually, and consequent problem is: 1, the easy oxidation and rusting of steel plate.2, easy scratch automobile.3, cost of production height.4, lighter collision easily causes the permanent deformation of guardrail, and influences attractive in appearance.5, manufacturing process easily causes serious environmental to pollute.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provide that a kind of shock resistance is good, cost is low, the life-span is long, safety is higher, environmental protection, the better high strength tubulose of result of use guardrail.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this high strength tubulose guardrail, it is characterized in that being provided with stretch-proof band and the body that is fixed on the stretch-proof band, body adopts the PVC material of enhancing modified to make, and the body top is provided with the shock resistance band.
Be the M type of circular arc depression in the middle of stretch-proof band described in the utility model cross section is, the body cross section is irregular cycle, and shock resistance band cross section is circular arc.
This practical utility model body adopts the PVC material of extra high molecular, need not anticorrosion, spray treatment aborning, real realization environmental protection, simultaneously because the PVC material is a renewable resource, and the production integrated cost of product is low, this tubulose guardrail frame for movement is irregular cycle, at the body top shock resistance band is arranged, but but the shock resistance band adopts a kind of or other reinforcing material in glass fiber that hot melt coats, carbon fiber, the metal.In body bottom the stretch-proof band is arranged, but the stretch-proof band adopts a kind of in steel band that hot melt coats, glass fiber, the carbon fiber or other can strengthen the material of tensile strength.
The utility model compared with prior art have high impact resistance more, better buffering, stronger stretch-proof effect, and structure is attractive in appearance, cost is low, the life-span is long, safety is higher, environmental protection.
