Other Data of Light Steel Building --1. Seismic resistance of light steel residential buildings: Because of the light weight of the steel structure building, metal material properties and to shear wall structure determines the seismic performance of light steel structure system of innate. Due to the seismic activity is move up and down, so with the fastening piece even with light steel structure formed a stable and safe box, not because of the earthquake shaking and collapse of the wall or floor fall endangers the personal safety. When the earthquake intensity is 9, it can meet the requirement of not falling down. --2. Light gauge steel residential sound insulation: 1). Sound insulation of wall≥45db 2). Floor impact sound pressure ≤70db thermal insulation according to requirement of the world climate,external walls, roof insulation layer thickness can be arbitrarily changed. --3. wind resistance Wind load can reach 12 typhoon(1.5KN/m2). --4. Light steel residential environmental protection: Eco recyclable steel, wood, plastic 100% can be recycled . --5. Light steel residential security: permanent buildings and color Steel sheet house, activity house is essentially the difference. Housing service life reached the requirements of the national standard for 50 years Advantage (1) Light steel house's structure parts produce as manufacturing factory type and high degree of mechanization, high degree of commercialization . (2) Light steel housing construction speed is fast, it is a civilization construction and will not affect the nearby residents (3) The steel structure of light gauge steel house is a sustainable development product of environmental protection. (4) Light steel house is light weight, seismic performance is good. (5) Because of the wall thickness of light steel structure housing is smaller .It can increase the effective use of the area than the brick concrete structure . (6) Compared to the light steel structure building with reinforced concrete residential, due to the light steel structure of the steel after recycling, but concrete cannot be recycled. later must be construction waste, causing environmental pressure and concrete need 40 years to completely dry, so easy to cause the indoor humidity, wet, is not conducive to human health. But light steel structure completely without concrete, and therefore does not exist the problem. (7) Light steel housing have good anti-seismic performance . Due to the seismic activity is about and activities, so screw nail is tight with light steel structure to composed of a safety box, can't because of the earthquake shaking and collapse of the wall or floor fall endangers the personal safety. (8) Light steel building construction using dry construction method, will not cause the waste of water , and save the cost.
