Classification of light steel construction
The so-called light steel structure usually refers to the structure consisting of the following steel: ① cold-formed thin-walled steel structure; ② hot-rolled light steel structure; ③ welded or high-frequency welded light steel structure; ④ light steel pipe structure ⑤ thin wall Welded composite beam and welded composite column structure. According to the current situation in our country, this kind of structure has been widely used in single-layer industrial plants, multi-storey industrial plants, office buildings and non-load-bearing components in high-rise buildings because of its extensive use and obvious advantages. First, the application of light steel structure 1, low-rise light steel Construction: low-rise light steel construction, refers to the two-story (including two) light steel housing construction, the main use of real abdominal or lattice-type portal plane steel frame structure system. At present, the main applications of light steel structure low-rise buildings are: industrial plants, hangars, waiting rooms, wharf buildings, supermarkets, farmers markets, catering and entertainment houses, sports facilities and various temporary buildings. China has built a gantry steel frame light steel structure housing more than 800 million square meters, and an annual increase of about 1 million square meters. 2, multi-story light steel construction: multi-story light steel building is another promising form of construction, the general can be defined below the 10-story residential; total height less than 24 meters of public buildings, the floor load is less than 8KN / M² industrial plant. This type of building more use of three-dimensional framework of the system can also be used plane steel structure system. Domestic multi-story light steel buildings are: residential, multi-storey industrial plants, schools, hospitals, offices, entertainment and other public buildings, supermarkets, retail, department stores and other commercial buildings, the old building plus layers, such as expansion.
