There Are Two Types Of Steel Structure

Steel structure is composed of steel material structure, is one of the main building structure type. The structure is mainly composed of steel and steel plate, steel column, steel truss and other components, the components or components are usually used between the weld, bolts or rivets connected. Because of its relatively light weight, and the construction is simple, widely used in large factories, venues, Steel Structure high-level areas.

Steel structure is composed of steel material structure, is one of the main building structure type. The structure is mainly composed of steel and steel plate, steel column, steel truss and other components, the components or components are usually used between the weld, bolts or rivets connected. Because of its relatively light weight, and the construction is simple, widely used in large factories, venues, high-level areas. According to different classification criteria are as follows:

First, the steel structure according to the use of two types: high steel structure, Steel Structure steel shell steel structure, industrial plant steel structure, light steel structure.

1, high steel structure

The towering structure includes TV tower, microwave tower, communication tower, high voltage transmission line tower, petrochemical tower, atmospheric monitoring tower, rocket tower, travel tower, drilling tower, exhaust tower, water tower, chimney, and most high Structures are made of steel structure. 336m high Heilongjiang TV Tower is China's highest steel structure of the multi-purpose TV tower, the same type of 200 ~ 300m steel tower there are many. China in the 20th century 60 - 70 years to build a large steel tower mast structure has 200m Guangzhou TV Tower, 210m Shanghai TV Tower, 194m Nanjing across the Yangtze River transmission line tower, 325m Beijing environmental climate mast. 1990 completed the 212m Shantou TV Tower, 260m Daqing TV Tower are also steel structure. Large and wide structure of the high tower is the communication tower and transmission tower, Steel Structure along with information and power development, this 50m steel tower will be around the Divine Land.

2, plate shell steel structure

Steel Structure Demand for closed containers, such as large oil depots, gas storage, furnace shell and other needs to accept the Chongqing steel structure of large internal forces and temperature changes in the blast furnace structure, large diameter high pressure oil pipeline are shell steel structure, there are some large water The structure of the ship gate is also the shell and shell structure.

3, industrial plant steel structure

Steel structure is usually used for heavy-duty workshop load-bearing skeleton, such as the metallurgical factory of the flat furnace workshop, the first rolling workshop, mixing furnace workshop, Steel Structure heavy machinery plant cast steel workshop, hydraulic press workshop, forging workshop, shipyard platform workshop, aircraft factory Of the assembly workshop, as well as other factories span the larger workshop roof, crane beam and so on. China's Anshan Iron and Steel, Wuhan Iron and Steel, Baotou Steel and Shanghai Baosteel and other well-known metallurgical complex of many workshops have chosen a variety of planning steel structure plant, Shanghai Heavy Machinery Plant hydraulic press workshop, Shanghai Jiangnan shipyard also has a huge steel Structure plant.

4, light steel structure

Light steel structure usually refers to the bar, small angle steel, thin-walled steel or welded steel plate made of the structure. Light steel structure is the strength of light weight, low cost, high degree of production and manufacturing factory, the site of the small workload, construction speed, with beautiful appearance, the internal wide, construction area and space utilization is high, so the construction of shopping malls Very competitive. In recent years, light steel structure in China to carry out rapid, the use of scale from the industrial plant, small and medium-sized housing construction, stadium stands awning, small warehouses, etc. to the shelter, villa.

Second, the construction of steel structure type in accordance with the structure of the division, can be divided into additional steel structure, tower steel structure, staircase steel structure, such as seven common steel structure type:

1, plus steel structure

Shaped steel as the main bearing beam, connecting the main wall or beam at both ends of the support point, the main structure should be laid above the pressure plate, and then laying steel, and the original structure of the surrounding bar connection, and finally pouring concrete. The following are the same as the "

2, the villa expansion of steel structure

Steel structure villa main structure beam, column, shelf support by the cold-formed thin-walled steel structure or composite beam composition. The use of steel structural components of light quality, easy to transport, installation, easy assembly and disassembly, expansion. The following are the same as the "

3, tower steel structure

The tower is a high-rise steel structure, the main structural material is steel pipe, Steel Structure tower widely used, can be used for factory chimney support, large building support, water tower tower, monitoring engineering, communication engineering and other special purposes. The following are the same as the "

4, staircase steel structure

Steel staircase support system is the staircase steel sloping beam as the main structural components, staircase ladder to the main plate, the railings in the form of parallel to the stairs oblique beam slash form. Its characteristics of small footprint, convenient construction, modeling casual, Steel Structure practical and strong.
