<input id="uauy4"></input> Strut is usually defined by the following structural steel : ① cold-formed steel ; structure ⑤ thin wooden partition composite beam welding and weld formation ; ② hot rollers light steel ; ③ welding or high frequency welding light steel ; ④ light steel structure the combination of the column .
1 Scope
According to China's current situation , it is because of their vast expense , have obvious advantages , the structure has been widely applied to a single industrial plant , multi-storey industrial plants, office buildings and high-rise buildings and other non- load-bearing components . For a single industrial plant Typically , H -shaped steel, welded connections C- or Z -shaped steel purlins, roofing systems or floor surface layer system with pressure- color plate , the top can be poured reinforced concrete beam light pressure plate can be used as needed , can also be matched with reinforcement. The retaining wall may also be used single or sandwich pressure plates , sandwich panels can be filled with a variety of internal insulation .
Two main advantages
⑴ short construction period : The biggest advantage of light steel structure , all of the components of the production plant joint on-site installation , on a smaller scale industrial plants generally only 45 days to two months , and the use of reinforced concrete building will have 8-12 months.
⑵ overall economy : Since the construction cycle is short, you can put to use in advance , it can be put in the time and the return on investment can be used to get ahead , because the project time is short ; using colorful color pressure plate , gorgeous and beautiful colorful color press plate , gorgeous , beautiful, dynamic sense to improve the surrounding environment , because the building itself is light weight , generally do not need to do pile , you can save investment , polystyrene foam sandwich board plus hexene or cotton insulation and other measures through the use of make insulation, heat insulation and sound insulation , as each chapter . Color galvanized steel is used as a substrate and an organic silicon surface , in addition to two two baking , durability is good, according to Chinese steel reinforced concrete structure has been lower than the current market price of the cost of light , when greater span of the plant , and its advantage is more obvious, it is competition, which is a big advantage.
⑶ seismic performance : As the steel structure is flexible , light weight, can effectively reduce the impact of the earthquake and disaster response , it is highly beneficial to the earthquake . China is a country with many earthquakes in the building earthquake zone , should promote the use of a lot of steel , will greatly reduce the earthquake disaster and casualties. Tangshan earthquake painful lessons should be remembered. At present, Tianjin has officially started light steel houses.
⑷ desirable to remove Removal: Having made that change or accident site owners are not satisfied with the external environment , the entire building can be demolished within a very short period of time , the loss is very small , and all of which are reinforced concrete buildings not available.
This is because of the many advantages of light steel structure , but with the recent fire, corrosion of new products emerging, light steel structure has been solved the shortcomings of poor corrosion resistance , making it the industrial plant and civilian facilities have been widely used .
