steel coil sheet Steel structure

Steel structure has the following characteristics:

First, the steel structure is light weight. Although the bulk density of the steel structure is large, it is much stronger in strength than other building materials, so that when the load and conditions are the same, the steel structure is lighter than other structures and is easy to transport and install. Large span.

Second, the plasticity of steel and toughness. Good plasticity, so that the steel structure is generally not due to accidental overload or partial overload and sudden fracture damage. Toughness is good, so that the steel structure of the strong adaptability to the dynamic load. These properties of steel provide a guarantee for the safety and reliability of steel structures.

Third, the steel is closer to homogeneous and isotropic. The internal structure of the steel is relatively uniform, very close to the homogeneous and isotropic body, in a certain range of stress is almost completely elastic. These properties are more consistent with the assumptions in the mechanical calculation, so the results of the steel structure are more realistic.

Fourth, the steel structure is simple, easy to use industrial production, construction and installation cycle is short. Steel structure from a variety of profiles, making simple. A large number of steel structures are specialized in the manufacture of metal structures manufacturing; high accuracy. Made of components shipped to the scene assembled, the use of bolts, and the structure of light, so the construction is convenient, short construction period. In addition, the built steel structure is also easy to disassemble, reinforcement or transformation.

Fifth, the steel structure of the good sealing. The airtightness and watertightness of the steel structure are better.

Six, the steel structure of the heat resistance is good, but the fire performance is poor. Steel heat and not high temperature. As the temperature increases, the strength decreases. When the surrounding radiation heat, the temperature above 150 degrees, it should take measures to block. If in the event of a fire, the structural temperature reaches more than 500 degrees, it may be all instantaneous collapse. In order to improve the fire resistance of the steel structure, usually with concrete or brick to wrap it up.

7, steel is easy to rust, should take protective measures. Steel is easy to rust in humid environments, especially in corrosive media, must be painted or galvanized, and should be regularly maintained during use.

Compared with other structures, steel structure has advantages in the use of functions, design, construction, and comprehensive economy. The advantages of steel structure in residential buildings are mainly reflected in the following aspects:

First, the steel structure of residential than the traditional building can better meet the building between the large open flexible requirements, and by reducing the cross-sectional area of the column and the use of lightweight wall panels, improve area utilization, indoor effective use area increased by about 6 %.

Second, the energy-saving effect is good, the wall using light energy-saving standard prefabricated wallboard instead of clay brick, good insulation properties, energy saving 50% per household per square meter can save the cost of 18 yuan.

Third, the steel structure system for residential buildings can give full play to the ductility of steel structure, plastic deformation ability, with excellent seismic performance, greatly improving the safety and reliability of residential. Especially in the case of earthquakes, typhoon disaster situation, to avoid the collapse of the building damage. Such as the 1995 Hanshin earthquake in 1999, the Taiwan earthquake did not collapse almost all of the H-beam steel structure of the building.
