Description

A kind of bakelite purlin and manufacture method thereof
Technical field
The present invention relates to building field, be specifically related to a kind of large-scale steel structure roofing or metope of being applied to Bakelite purlin and manufacture method thereof.
Background technology
Due to steel building have with steel province, cost economic, the supply of material rapidly, simple installation and profile The advantage such as succinct, at home and abroad obtains developing rapidly with widely used as a kind of commodity.External six The ten's started to widely apply, and nowadays, light weight steel structure system is in the low-rise building city of non-livability Occupying an leading position on field, its purposes is extremely wide, including cold-formed steel residence structure (1~3 layer of villa house), the building of commercial use such as warehouse, small-sized storied office building, garage, supermarket; Build such as Factory Building, material recovery station, automobile production Factory Building and chemical plant including manufacture and processing industry type Deng;Also include community and public building such as school, City Hall, stadiums etc..
The First Line defendd to external world of building is made up of metope and roofing, they be also subjected to simultaneously as The structural load effect such as wind, snow load, and these loads are passed on secondary supporting structure.Roof purline As aggregated(particle) structure most important in steel structural roof, not only occupy the biggest in the cost of roofing system Ratio, and play great effect.Transmitted, by metope and roofing, the load of coming by receiving, and by it Pass to the main structure of post and crossbeam composition equably up, bear wind load, snow load and other load and incite somebody to action It is delivered to building foundation.
In early days, China is mainly hot-rolled steel section for the purlin of roofing, but it is from great, steel quantity consumption Many.Conventional freely-supported purlin mostly controls for amount of deflection, and intensity tends not to play one's part to the full.Later The light gauge cold-formed steel shape of exploitation have meterial saving and high efficiency, consumption steel few, from heavy and light, to manufacture transport easy etc. excellent Point, is used as the purlin of steel structural roof in a large number.But for some border on the sea building, steel rolling mill, smelting Industry in the corrosive environment such as factory, chemical fertilizer factory, Aluminum oxidation workshop, chemicals workshop, mariculture Building, metal material purlin easily corrodes, and brings puzzlement greatly to steel structural roof building.
Traditional fiberglass in the successful Application of corrosion-resistant field more than 80 years, such as chemical storage tank, ground Lower water supply and sewerage pipeline, marine pleasure-boat, wind power facility etc., the anticorrosion of its brilliance, ageing-resistant performance obtain Arrive extensive approval.It is although the purlin excellent anti-corrosion performance that this composite makes, lightweight, But, it is easy to burning under the high temperature conditions, causes fracture, caves in, and cost of manufacture is high.
Therefore, how to promote roofing or the corrosion resistance of metope purlin, anti-flammability and mechanical property are to work as The urgent needs of front architectural structural system.
