Technical performance of steel structure
Thermal insulation and energy-saving technology for light steel structures ensures that the insulation effect is achieved. The insulation materials used in the exterior walls and roofs of buildings can be used for a long time and can provide thermal insulation. Generally, in addition to filling glass fiber mesh cloth between the walls and columns of light steel structure residential buildings, a layer of insulation material is also pasted on the outside of the walls to effectively isolate the thermal bridge from the wall columns to the exterior wall panels; Fill the shelves between floors with fiberglass to reduce heat transfer through the floors; All interior walls and columns are filled with fiberglass to reduce heat transfer between the walls.
One of the most critical issues in fire prevention technology for light steel structures is the application of fire prevention technology. The fire resistance rating of light steel structure residential buildings is level four. Fireproof gypsum boards are pasted on both sides of the walls and the ceiling of the building in light steel structure residential buildings. For ordinary firewalls and partition walls, 25.4mm thick (1 inch) gypsum boards are used for protection to meet the 1-hour fire protection requirement. In addition, glass fibers filled between wall columns and floor joists also play a positive role in fire prevention and heat transfer.
The sound insulation technology of light steel structure is filled with glass wool between the inner and outer walls and floor joists, effectively preventing the audio part transmitted through the air. For the impact sound transmitted through solids, the following structural treatment is made: for the partition wall, two wall columns are used to form a two wall body with a middle gap; For the small keel of the fixed gypsum board used for the ceiling, an elastic structure with small grooves is used to effectively reduce the solid sound propagation between floors.

The Development History of Steel Structures
Although China made early achievements in iron structures, it remained at the level of iron buildings for a long time. It was not until the end of the 19th century that China began to adopt modern steel structures. After the establishment of the People's Republic of China, the application of steel structures has made great progress, far exceeding the past in both quantity and quality. The floor of the light steel structure is composed of cold-formed thin-walled steel frames or composite beams, floor OSB structural plates, supports, connectors, etc. The materials used are oriented strand board, cement fiberboard, and plywood. These lightweight floors can withstand a load of 316-365 kilograms per square meter.
