Technical field
The present invention relates to windproof breast board of a kind of bridge and preparation method thereof and mounting method.
Background technology
Construct a bridge on the marine site, because the waters meteorological condition complexity of being crossed over, typhoon, cyclone, thunderstorm and sudden weather happen occasionally, and crosswind influences vehicle driving safety probably, even causes accident.The air partition global anti-wind system being set for marine bridge is one of effective way that addresses the above problem, but existing air partition plate is the slabbed construction by acrylic sheet material, tempered glass plastic production, have following defective: weight is big, life-span is short, and making and installation cost are higher, and security performance is relatively poor, impact strength is low, fracture is dangerous high easily, non-refractory, easy deformation deterioration, and light transmission is poor.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of C shape bridge air partition plate and preparation method thereof and construction method of installation, solve existing air partition panel products life-span weak point, making and the high technical problem of installation cost.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of C shape bridge air partition plate is bar shaped, and it is characterized in that: the cross section of air partition plate is a C shape, is to be bent by co-extrusion UV strata carbonic ester PC endurance sheet material to form.
A kind of preparation method of C shape bridge air partition plate is characterized in that:
Step 6, the demoulding of air partition plate, demould time is 5～8 minutes, pastes simultaneously and changes flexible PE diaphragm.
Step 7, air partition plate cooling promptly is flat on cooling in the thermostatic chamber after the demoulding of air partition plate, paste simultaneously and change flexible PE diaphragm.
Step 8, air partition plate are cut edge, and promptly adopt special-purpose side cut equipment to cut two straight flanges of air partition plate simultaneously, paste simultaneously and change flexible PE diaphragm.
Step 9, air partition plate otch UV spraying and solidifying, promptly to air partition plate side cut section spraying antiultraviolet UV coating, spraying is carried out ultraviolet curing by UV curing machine later, pastes simultaneously and changes flexible PE diaphragm.
In the described step 3, the heat drying process adopts non-linear heating mode, and the vacuum drying oven furnace temperature is stabilized in 150 ± 3 ℃, dry 22～36 hours.
In the described step 4, be 18～25 minutes heat time heating time.
In the described step 5, mould is selected the good aluminum dipping form of heat conductivility for use, and is preheated to 45 ℃ before use.
In the described step 7, interior temperature is controlled at 35 ± 2 ℃, and be 24 hours cool time.
A kind of construction method of installation of C shape bridge air partition plate is characterized in that:
In the described step 1, the external coating of rail post has antifouling paint.
Described every pair of one of them clamping plate of C clamp plate are connected with semicircle base plate, and semicircle base plate is connected with the rail post bolt.
There is anti-skidding line on the surface of described damping rubber bar.
Beneficial effect of the present invention is as follows:
It is the PC force-bearing plate of Merlon that the present invention has adopted raw material, and co-extrusion UV layer is processed as the technology of C shape air partition plate then, can reduce by 3～4 grades of wind-force in the air partition scope, for the normal operation of bridge spanning the sea provides sound assurance, and has following advantage:
1, construction cost is low.The present invention can make air partition plate processing cost reduce, and at present, traditional air partition plate price of 2000mm * 310mm specification reaches 3000 yuan/piece, and the cost of production of the air partition plate of the same specification of the present invention only is 1000 yuans, saves 2000 yuan/piece than traditional product.
2, easy for installation.The air partition plate that adopts this method to make is in light weight, is convenient to carrying, boring, blocks when installing not easy fracture, and construction is simple, good processability.
3, life-saving.In polycarbonate force-bearing plate surface co-extrusion one deck antiultraviolet UV coating, prevent the destruction of ultraviolet ray to polycarbonate, the durability of polycarbafil PC force-bearing plate, delaying aging has increased service life.The C tee section helps reducing damage, prolongs life of product.
4, C shape air partition plate is used for the bridge traffic engineering, and security performance is good.At first be that impact resistance is strong: impact strength is 250～300 times of simple glass, is 20～30 times of acrylic sheet material, is 2～5 times of tempered glass, fracture dangerous low; Next is a temperature tolerance height, not yielding, can not cause quality badnesses such as distortion in 40 ℃～+ 120 ℃ temperature ranges Celsius; It three is that light transmission is good, and light transmittance reaches more than 80%.
