Roofing system

Light steel roof system for residential buildings

It is composed of roof truss, structural OSB panel, waterproof layer, light roofing tile (metal or asphalt tile) and related connecting parts. Maite building light steel structure roof, appearance can be a variety of combinations. There are also a variety of materials. On the premise of ensuring the waterproof technology, the appearance has many options.

The wall structure

The wall of light steel structure residence is mainly composed of wall frame column, wall top beam, wall bottom beam, wall support, wall board and connecting parts. Light steel structure residential building will cross wall inside as a general structure of the main wall, wall column for C shape light steel structures, according to the wall thickness of load, usually is 0.84 ~ 2 mm, wall column spacing generally is 400 ~ 600 mm, light steel structure residential building the wall body structure arrangement, can be effective and reliable delivery under vertical load, and the arrangement is convenient.

Technical performance

Thermal insulation energy-saving technology light steel structure to ensure the thermal insulation effect, thermal insulation materials used in the building's external walls and roof can be used for a long time and thermal insulation. Generally, in light steel structure residential buildings, in addition to filling glass fiber mesh cloth between the wall columns, a layer of insulation material is pasted on the outside of the wall, effectively cutting off the thermal bridge from the wall columns to the wall panels. Glass fiber is filled in the joists between floors to reduce heat transfer through the floors. All interior walls are filled with fiberglass between the wall columns to reduce heat transfer between the walls.

Fire prevention technology light steel structure one of the most critical problems is the application of fire prevention technology, light steel structure residential fire resistance level for four. Light steel structure residential building at both sides of the wall and floor of the smallpox of fire prevention plasterboard, for common firewall and the ledger wall with 25.4 mm (1 inch) thick plasterboard protection, in order to achieve an hour fire prevention requirements, in the wall between the wall and floor joists between pillars fill glass fiber for fire prevention and heat transfer also play a positive role in protecting.

The light steel structure is filled with glass wool between the internal and external walls and the floor joists, which effectively prevents the audio part transmitted through the air. For the impact sound transmitted through the solid, the structural treatment is as follows: for the partition wall, two wall columns are used to form two walls with intermediate gaps; And to the fixed plasterboard with condole top small keel, with the elastic structure that has small cut groove in order to reduce the solid sound transmission between floor effectively.
