Steel structure factory buildings are suitable for buildings that require area. Its large span and small column area can greatly reduce the waste of indoor area and increase the usable area. Compared with single-story steel structure factories, multi-story steel structure factories can obtain more practical space under the same building area, so they have become the first choice for many companies to build factories.
1. High strength and light weight
Steel has higher strength and modulus of elasticity compared to other building materials such as concrete, masonry and wood. Therefore, structural members are light in weight and small in cross-section, and are particularly suitable for components and structures with large spans and large loads. Steel structures have lighter weight under the same stress conditions.
2. Small cross-section and large space
Due to the high strength of steel, its small cross-section takes up little space. Taking a simply supported beam under the same stress conditions as an example, the height of a concrete beam is usually 1/10-1/8 of the span, while the height of a steel beam is about 1/16-1/12. If the steel beam has sufficient lateral support, it can even reach 1/20, effectively increasing the net height between floors of the steel structure factory building. With the same beam height, the steel structure bays are 50% larger than the concrete structure bays, which can better meet the requirements of large span prefabricated steel structure workshop.
3. The material is uniform, has good plasticity and toughness, and has excellent seismic resistance.
Because the steel structure is a uniform, nearly isotropic homogeneous body, it has good plasticity and toughness. Therefore, the actual working performance of the steel structure is consistent with the currently used theoretical calculation model, so the reliability is high.
4. Simple production and short construction period
The materials used in multi-story steel structure factories are simple, mostly finished or semi-finished materials, and the processing is relatively simple. They can be mechanically operated, easy to shape and standardize, and have a high degree of industrial production. Therefore, steel components are generally manufactured in specialized structural processing plants with high precision, stable quality and low labor intensity.
5. Energy saving and environmental protection
Compared with traditional masonry structures and concrete structures, steel structure workshops belong to a green building structure system. The walls of steel structure factories mostly use new lightweight composite sandwich wall panels, such as metal rock wool sandwich wall panel. The floors mostly use composite floor slabs, such as PPGI corrugated sheet and other materials. Complying with the requirements of building energy conservation and environmental protection, it can achieve the goal of energy saving of 50%, greatly saving energy.
