The utility model technical problem to be solved is to overcome existing above-mentioned deficiency in the prior art, and provides the rational more highway of a kind of structure design to use the high strength guardrail board.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this highway comprises the plate body that is made of resin with the high strength guardrail board; In plate body, be provided with the reinforcing band consistent with the plate body bearing of trend; It is characterized in that: described reinforcing band comprises the horizontal blend and the perpendicular fiber of both direction at least on the cross section; Described horizontal blend is made up of fiber and steel cord, and all blends and fiber in the reinforcing band all are fixed together.Its effect is: strengthen stretch-proof ability and jolt capacity; Simultaneously, the tensile strength of steel cord superelevation and lower material price can strengthen the intensity of reinforcing band, better reduce cost.
Steel cord in the said horizontal blend of the utility model evenly is arranged in the middle of the fiber, and promptly middle is the steel cord, and both sides are fibers up and down, and the steel cord accounts for 20～30% of reinforcing band sum, can strengthen the intensity of reinforcing band thus, reduces cost.
The diameter of steel cord is 0.2～2mm in the said reinforcing band of the utility model.With convenient braiding and fixing, has enough intensity again.
Horizontal blend and perpendicular fiber in the said reinforcing band of the utility model are fixed together through braiding, and they are coated and fixed together through hot melt and described plate body.Make reinforcing band not only have the advantage of polyster fibre strong shock resistance, also have long service life, the advantage that anti-shearing force is big.
The described reinforcing band of the utility model is a kind of in one deck reinforcing band or two-layer reinforcing band or the three layers of reinforcing band.Can select the number of plies of reinforcing band according to required intensity.
Sticking press fit between every layer of the described reinforcing band of the utility model.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design: good impact resistance not only, and tensile strength is higher than the strength criterion of steel guardrail, also has anti-shearing force preferably; 2, cost is low: comprise that cost of production and installation and maintenance cost are all lower, it is in light weight, and transportation and install does not simply need to safeguard that the surface is difficult for piling up dust, can clean voluntarily through the rainy day; 3, security performance is high: advantages of higher tensile strength has improved the impact force of guardrail greatly, has better resiliency, has reduced the secondary injury of people's car.4, long service life: than steel guard rail application life above 1 times.
