Light steel structure In order to ensure the thermal insulation effect, the thermal insulation materials used in the external walls and roofs of buildings can be used for a long time and can be thermal insulation. Generally, in addition to filling glass fiber mesh cloth between the wall pillars, a layer of thermal insulation material is pasted on the outside of the wall, effectively cutting off the thermal bridge from the wall pillars to the outer wall panels; The joists between the floors are filled with glass fibers to reduce heat transfer through the floors; All interior wall walls are filled with fiberglass between the wall pillars to reduce heat transfer between household walls.
One of the most critical issues of light steel structure is the application of fire prevention technology, and the fire resistance grade of light steel structure residential buildings is four grades. Building light steel structure housing on both sides of the wall and the ceiling of the floor fire gypsum board, for the ordinary firewall and household wall with 25.4 mm thick (1 inch) gypsum board protection, in order to achieve 1 hour fire prevention requirements, in addition between the wall column and the floor joist filled with glass fiber for fire prevention and heat transfer also played a positive role in the protection.
The light steel structure is filled with glass wool between the inner and outer walls and the floor joists, which effectively prevents the audio part transmitted through the air. For the impact sound transmitted through the solid, the following structural treatment is made: for the household wall, two wall pillars are used to form two walls with intermediate gaps; For the small keel used to fix the gypsum board for the ceiling, the elastic structure with small grooves is used to effectively reduce the solid sound propagation between floors.
