Abstract

The utility model relates to a glass fiber reinforced plastic barrier for expressway, which has a higher intensity and rigidity, erosion resistance, light weight and can be made into various colors. A strengthened rubber is arranged inside a safety guard barrier. The safety guard barrier contains the strengthened rubber inside the safety guard barrier. The strengthened rubber may be metal bar or metal net. The utility model is of simpler art and easy implementation, which is fit for closing highway.

Description

Speedway glass fiber reinforced plastic fence plate

Technical field:

The utility model relates to the traffic safety technology field, and exactly it is a kind of speedway glass fiber reinforced plastic fence plate.

Background technology:

Along with the raising of the economic comprehensive strength of China, speedway extends in all direction, and still, because the speed of a motor vehicle is very fast on the speedway, for the sake of security, with express-way guard-rail plates speedway is closed usually, ensures traffic safety.What existing express-way guard-rail plates generally adopted is the guardrail board that steel plate is made, this guardrail board is owing to be metal material manufacturing, thereby processing more complicated, the technological equipment that needs during manufacturing is many, production cycle is long, and transit link is many, and cost is higher, product price is also higher, and corrosion resistance is relatively poor.China Patent No.: 97275376 disclose the utility model patent that a kind of name is called " speedway guardrail ", it has just increased aluminium coat, strengthened anti-corrosion function, but cost is still higher, China Patent No.: 99222636 disclose the utility model patent that a kind of name is called " speedway glass fiber reinforced plastic fence ", though it makes the higher easy fracture of fragility for glass fiber reinforced plastic.

Summary of the invention:

The purpose of this utility model provides a kind of good antiseptic property that has, and speedway glass fiber reinforced plastic fence plate in light weight, that light transmission is good, it can also the one-tenth shades of colour, the outward appearance light is attractive in appearance.Its skin adopts glass fiber reinforced plastic to make, and the center accompanies the metal reinforcing mat, has higher intensity and stiffness, and has good anti-corrosion, and atmosphere, water, height gentle generally acid, alkali, salt, the oil of concentration are all had resistivity preferably, and is durable in use.It is that reinforcing rib (2) is housed in guardrail board (1), and guardrail board (1) is completely contained in reinforcing rib (2) in the guardrail board (1).Reinforcing rib (2) can be bonding jumper or wire lath.

The utility model has the advantages that: when having higher-strength and height, also have good antiseptic property, and weight is lighter, the light transmittance height, can the one-tenth shades of colour, the outward appearance light is attractive in appearance, helps producing, transportation, installs and store, can produce on the spot, install on the spot, with glass fiber reinforced plastic make guardrail board can simplified design in road construction project, quicken programming, reduce construction costs, accelerating road construction speed, is the substitute products of metal guardrail board.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

The guardrail board skin is a glass-reinforced plastic material, and glass fiber reinforced plastic is by glass glass dimension reinforcing material and synthetic resin cement, adds a little auxiliary, is composited through the resin crosslinks curing reaction.Herewith, the specification of producing the glass fiber reinforced plastic fence plate and at first be by guardrail board makes mould, and bed die can use concrete, all can of making such as plank glass fiber reinforced plastic.Mold is the most handy to have the good steel plate of fineness of constant weight to make.How much quantity that mold is manufactured determines by production scale.On long more than ten meter production platform, put one deck mylar.Earlier the four-layer glass cloth is layered on the polyester film, above the resin of converting is poured on, fast resin is wipeed off with scraper plate, make glass fabric all invade profit among resin, reinforcing rib is placed on middle, and then put the triplex glass cloth, the resin of once converting again, thicker polyester film is placed on the top, with scraper plate from the centre to around scrape bubble, move on to this glass fiber reinforced plastic flat board on the bed die reposefully rapidly, put the lastblock patrix above again, above being pressed in reposefully with heavier thing, then do second, be pressed in the thing on the mould.Second overlapping being placed on the mould, put a mold above again, press thing and can put tens to tens like this overlappingly.Solidify the twenty four hours rear demoulding, advance to draw edging all around.It promptly is product.As the better quality of producing with the mechanical injection moulding, speed is faster.The utility model safety can adopt existing metal guardrail board that connected mode is installed, thereby mounting process is fairly simple, is fit to promote rapidly.

Claims

1, speedway glass fiber reinforced plastic fence plate is characterized in that: reinforcing rib (2) is housed in guardrail board (1), and guardrail board (1) is completely contained in reinforcing rib (2) in the guardrail board (1).

2, a kind of speedway glass fiber reinforced plastic fence plate according to claim 1, it is characterized in that: reinforcing rib (2) can be bonding jumper or wire lath.
