Advantages of steel structure Advantages of steel structure Steel structure and other materials compared to the following characteristics:
the steel structure Light weight Steel structure Light weight Steel structure Weight Light steel structure Bulk density Although large and single with other building materials Than it is much stronger, so when the load and the same conditions, the steel structure than other structures light, easy to transport and installation, and can span a greater span. The weight of residential buildings built with steel structures is about 1/2 of the reinforced concrete houses. It can meet the needs of large-scale residential buildings. The use area is about 4% higher than that of reinforced concrete buildings.
the plasticity and toughness of steel Good plasticity and toughness of steel Good plasticity 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.
the steel is closer to the homogeneous and isotropic steel is closer to the homogeneous and isotropic body of steel closer to the homogeneous and isotropic body of the internal structure of the steel is relatively uniform, very close to 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.
the steel structure of the air tightness and good watertight steel structure of the air tightness and water tightness of the steel structure is better air tightness and watertight.
the design style flexible design style flexible, rich and rich. The In the case of the same beam height, the steel structure of the open space than the concrete structure of the large 50%, so that the building layout more flexible.
steel structure steel structure construction construction is simple and simple, simple construction and construction cycle short construction and installation cycle of short steel structure by a variety of profiles, the production is 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.
the use of steel structure can effectively protect the environment Steel structure can effectively protect the environment Steel structure can effectively protect the environment, the specific performance in three areas: First, compared with concrete, can be dry construction, resulting in small noise, dust The second is due to weight loss, the basic construction of less soil, the destruction of land resources, in addition to a large number of concrete to reduce the amount of excavation, is conducive to the protection of the ecological environment; Third, the construction life after the expiration of life, After the demolition of the structure, the amount of solid waste generated is small, and the scrap resource recovery value is high.
the degree of steel production of industrial production of high steel structure of the degree of industrialization of high steel structure of a high degree of industrial production, and easy to machinery manufacturing, intensive production, high precision, easy installation, easy to guarantee the quality, can build a real housing production plant, Factories, industrial plants and other factories. The development of steel structure, to create and promote the development of hundreds of new industries. H-beam advantages
