Welcome to Qingdao Steel Building Co., Ltd.
Steel structure building is composed by steel structure material, is one of the main building structure types.Structure is mainly made of steel and steel plate, steel column, steel truss girder artifacts, such as weld is required between each components or parts, bolt, or rivet connection.Because of its weight is lighter, and the construction is simple, widely used in large factories, stadiums, high-rise, and other fields.
What is steel structure building?
The characteristics of steel structure building
Steel is characterized by high strength, light weight, good overall stiffness and deformation ability, therefore, to build large span and super high, super-heavy buildings is suitable;Homogeneous and isotropic materials is good, is a ideal elastic body, the most in line with the general engineering mechanics basic assumption;Material plasticity and toughness, good can have large deformation, can bear dynamic load;Short construction period;Its high degree of industrialization, high mechanization degree of specialization of production can be performed. Steel structure components are easy to manufacture, site assembly in the factory.Mechanization of factory manufacture steel structure component products of high precision, high efficiency, site assembly speed up, short time limit for a project.Steel structure is one of the most industrialized structure.
Steel structure building fireproof performance
When the temperature was below 150 ℃, the steel properties changed little.Thus the steel structure is suitable for the hot shop, but the structure surface at the thermal radiation of about 150 ℃, to adopt heat insulation board to protect it.Temperature at 300 ℃ to 400 ℃. The steel strength and elastic modulus were decreased significantly, the temperature about 600 ℃, the steel strength tends to zero.In buildings with special fire protection demand, steel structure must be preserved with refractory materials in order to improve the fire resistance rating.
The application of steel structure building
Steel structure is widely used in prefabricated steel buildings, steel structure buildings,steel hangar kits, steel hall, steel structure storage shed, steel villa frame, steel structure warehouse, steel structure workshop, steel construction building,commercial buildings, aircraft hangars, stands, platform, indoor horse arena churches,Logistics Warehouse,apartment building, office building, steel hotel building, steel structure mezzanine, industrial buildings, processing plants, steel warehouses, shopping malls, poultry houses,poultry farm building, cow shed, dairy farm building, pig building house goat building house, agricultural buildings and many other steel structures. bclasse.
