Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates. The components or between the components are usually connected by welding, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields.
Steel structures are classified according to different installation standards as follows: According to their use, there are four types of steel structures: high-rise steel structures, plate and shell steel structures, industrial plant steel structures and light steel structures.
1. Installation of high-rise steel structure
The towering structure includes TV tower, microwave tower, communication tower, high voltage transmission line tower, petrochemical tower, air monitoring tower, rocket launching tower, tourism tower, drilling tower, exhaust tower, water tower, chimney and so on. The towering structures are mostly steel.
2. Plate and shell steel structure installation
Containers with airtight requirements, such as large oil storage tanks, gas storage, furnace shells, etc. Can accept the high internal force and temperature change of steel structure. Large diameter high pressure oil pipeline is plate shell steel structure, some large hydraulic building lock gate is plate shell structure.
3. Steel structure installation of industrial workshop
Steel structures are usually used as load-bearing frames in heavy workshops, such as open hearth workshops, rolling workshops, mixer workshops in metallurgical factories, steel casting workshops, hydraulic press workshops, forging workshops in heavy machinery factories, slipway workshops in shipyards, assembly workshops in aircraft factories, roofs, crane beams, etc. Other factories with large spans. Many famous metallurgical group companies, such as China Anshan Iron and Steel, Wuhan Iron and Steel, Baotou Iron and Steel, Shanghai Baosteel, have chosen various planned steel structure plants.
4. Light steel structure installation
Light steel structure usually refers to the structure made by welding of round steel, small Angle steel, thin wall steel or thin steel plate. The advantages of light steel structure are light weight, low cost, high degree of industrialization of production and manufacturing, small workload of on-site equipment, fast construction speed, beautiful appearance, wide interior, high utilization rate of building area and space, very competitive in the construction of shopping malls. In recent years, light steel structure has developed rapidly in China, and its application scale has expanded from industrial plants, small and medium-sized houses, stadium bleachers awning and small warehouses to houses and villas.
