First, the characteristics of the steel structure
1. High strength: Steel is a high-strength material that can obtain greater strength at a smaller cross-sectional size, and the bearing capacity is stronger than that of traditional building materials.
2. Lightweight: The unit weight of the steel structure is lighter than that of the brick-concrete structure, which can reduce the self-weight of the building, save materials and reduce the scale of the foundation.
3. Corrosion resistance: The steel can be waterproof, fireproof and anti-corrosion, and can prevent oxidation and corrosion after electroplating or hot-dip galvanizing treatment.
4. Fast construction: The steel structure can be prefabricated and manufactured and installed on site, which greatly shortens the construction period and saves manpower and material costs.
Second, the application range of steel structure
1. Industrial field: Steel structure is widely used in the industrial field, which can be used in manufacturing workshops, workshops, warehouses and other facilities, and usually adopts the factory construction method of large span, high space and large space, and no columns to meet the requirements of industrial production.
2. Civil buildings: Steel structures are increasingly used in civil buildings, which can be used to build villas, high-rise residences, commercial complexes and other buildings, and its lightweight, energy-saving and consumption-reducing characteristics make it an important choice for buildings in the new era.
3. Bridge field: Computer-aided design and manufacturing software is used in the design and manufacturing process of steel structure bridges to ensure their quality and reliability. The span range and carrying capacity of steel bridges also far exceed those of traditional concrete bridges.
4. Protective facilities: Steel structures can also be used to build various protective facilities, such as flood control levees, wind power towers, communication towers, etc., and their sturdiness and durability meet the requirements of various harsh environments.
【Conclusion】 Due to the characteristics of high strength, light weight, corrosion resistance and fast construction, steel structure is widely used in industrial, civil, bridge and other fields. With the continuous improvement of technology, the future application prospects of steel structure will be broader.
