Guangzhou Steel News: Steel construction engineering new technology - Steel construction technique residence
1. The main technical content
A steel structure as a residence of the main load-bearing structure system, for low-density living so using cold-formed steel structural system based, plus plasterboard wall to wall studs, floor grate for the C-type light board; for multilayer live so steel frame construction system should adopt concrete floor slabs, walls of precast lightweight panel or light block. Multilayer steel structure residence in another direction is the use of light steel structure with steel plate shear wall or mixed with ordinary steel; the mixing structure for senior residences, places of steel frame and cylinder combination consisting of concrete or steel support frame structure.
2. Technical Specifications
For low-rise cold-formed steel residence system, the total amount of steel structure is 22 ~ 25kg / m, bay size is 3.3 ~ 4.8m; multistory steel frame shelter system, its steel construction steel consumption is 35 ~ 40kg / m , bay dimensions are 3.3 ~ 4.5m is appropriate; tall steel frame structure or steel mixing braced steel frame system, its steel construction steel consumption is about 50kg / m, open and asked the size of 3.3 ~ 7.2m is appropriate.
3. Scope
Cold-formed steel can be widely used in the construction of low-rise residences (1-3 layers); steel frame construction can be widely used in the construction of multi-residence (4-7 layers); mixed structure of steel and concrete or steel support frame structure It can be used in the construction of high-rise residence (9 to 24 layers). Steel structure residence construction industry as the goal to be to do a good job of supporting wallboard job to do a pilot project based on the promotion of steel structure residence job.
4. Typical project has been applied
Senior residence project hometown Wuhan century, Dujiangyan Yiyuan happy home residence residential steel construction, Beijing Jin Chen apartments. Guangzhou Steel
