Introduction to Steel Structure
Steel structure is a form of building structure mainly composed of steel plates, profiled steel, steel pipes, steel cables, etc., connected by welds, bolts or rivets. Compared with other structural forms such as reinforced concrete structures, masonry structures such as masonry, steel structures not only have many advantages such as high strength, light weight, good plastic toughness and seismic performance, but also suitable for mechanized processing, high degree of industrialization, and construction period. short. Since materials such as cement, sand and gravel are rarely used, environmental pollution problems such as dust, construction waste and noise have been greatly reduced.
As one of the most important building structures, steel structures are widely used in housing construction, machinery, energy, municipal facilities and other industries. There is no unified standard for the classification of steel structures. According to the application field, it can be divided into equipment steel structures (sealed pressure vessel steel structures, tower mast steel structures, ship and marine steel structures, water conservancy steel structures, coal power steel structures, drill tools and drill steel structures). , underground steel structure, etc.), building heavy steel structure (high-rise steel structure, heavy workshop, etc.), building light steel structure (light workshop, steel structure residential, etc.), bridge steel structure, space steel structure and other five categories.
