A nickel-phosphorous alloy plating is arranged on the surface of the spherical crown lining board. Protective rust layers are arranged on the surfaces of the upper support board and the lower support board. The weather-proof steel support for the bridge, disclosed by the invention, is advantaged in that the weather-proof steel support is simply structured and reasonably designed; the weather-proof steel support exerts very good long-term corrosion resistance and excellent wear-resisting property; the service life of the weather-proof steel support is long; the weather-proof steel support is favorable for environmental protection and cost reduction; and the weather-proof steel support does not need post-stage paint maintenance.
Description
Technical field
The invention belongs to technical field of bridge, particularly relate to a kind of bridge weathering steel bearing.
Background technology
The corrosion of steel is a general and serious problem, the loss that wherein atmospheric corrosion causes accounts for the half of whole corrosion loss, massive losses is brought to national economy, add up according to some industrially developed country, the economic loss caused due to corrosion of steel structure every year accounts for 2% ~ 4% of national economy total output value.At present, the economic loss that the whole world causes because of corrosion of steel structure is every year up to more than hundreds billion of dollar, and therefore, hold corrosion-prone problem in an atmosphere to solve steel, people start to develop weathering steel.
Bridge pad is as working the critical component formed a connecting link and act between beam body and pier, its durability directly has influence on the application life of bridge engineering.Current bridge pad mainly adopts the modes such as common iron+oil paint coating, needs the maintenances such as annual income paint, once application was lost efficacy, bearing corrosion was very serious, directly has influence on the application life of bearing.
Therefore, the direction becoming these those skilled in the art and make great efforts how is solved the problems of the technologies described above.
Summary of the invention
Object of the present invention is just to provide a kind of bridge weathering steel bearing, can solve above-mentioned the deficiencies in the prior art part completely.
Object of the present invention is realized by following technical proposals:
A kind of bridge weathering steel bearing, comprise upper bracket plate and lower support plate, between upper lower support plate, install spherical crown liner plate, described upper bracket plate, spherical crown liner plate and lower support plate are weathering steel and make, and spherical crown liner plate has the person of outstanding talent gram surface that energy metal surface mirror processing method processes.
As preferably, described spherical crown backing surface is provided with nickel-phosphorus alloy coating.
As preferably, described upper lower support plate surface arranges protective rust.
As preferably, described upper bracket plate bottom surface is provided with the groove mated with lower support plate.
As preferably; described upper bracket plate bottom surface is provided with side direction block along along bridge in both sides, lower support plate top; this side direction block is bolted on bottom upper bracket plate; and shear-pin is combined with between upper bracket plate and side direction block; described block is the block that weathering steel is made, and arranges protective rust from the teeth outwards.
As preferably; described upper bracket plate bottom surface is provided with side direction block along direction across bridge in both sides, lower support plate top; this side direction block is bolted on bottom upper bracket plate; and shear-pin is combined with between upper bracket plate and side direction block; described block is the block that weathering steel is made, and arranges protective rust from the teeth outwards.
The main steel part of bearing of the present invention all adopts weathering steel to make, the corrosion resistance index of this bearing weathering steel is more than 6.0 or 6.0, atmospheric corrosion resistance is 2 ~ 8 times of common straightcarbon steel, and service time is longer, anti-corrosion effect is more outstanding, and therefore this bearing has very outstanding anticorrosion ability.And-60 DEG C of low temperature V-type impact tests absorb energy and are not less than 47KV
2/ J.
Further; the main steel piece surface of this bearing adopts surface stabilizing treatment; even, the fine and close protective rust of one deck is formed on weathering steel surface; thus make weathering steel in use more attractive in appearance; also prevent rust liquid to run off simultaneously, solve exposed weathering steel and to become rusty before rusty scale is stablized in generation the pollution problem of water to environment.
And spherical crown liner plate sphere adopts person of outstanding talent's gram energy processing method to process, and arranges nickel-phosphorus alloy coating.Spherical crown backing surface fineness is made to reach as high as Ra0.02 μm of super mirror effect.Nickel-phosphorus alloy coating dense non-porous gap, hardness reach as high as more than 1000HV, and with the good bonding strength of base material, decay resistance, anti-wear performance are all better than 1Cr18Ni9Ti stainless steel.
Compared with prior art, beneficial effect of the present invention is: structure is simple, and reasonable in design, have good long-effective corrosion performance, anti-wear performance is outstanding, long service life, is conducive to environmental protection, and safeguards without the need to later stage paint, is conducive to reducing costs.
