How to improve the fire resistance of steel factory buildings?
Steel structure reinforcement
When designing the steel structure factory, the stability of the steel structure shall be considered emphatically, and the stability of the steel structure shall be strengthened by changing the structure. According to the distribution of the steel structure, the load, node performance and transfer mode should be reasonably changed by adding member support, prestress and space cooperation.
Improve the fire protection performance of steel factory buildings
Steel directly affects the fire resistance of steel structure workshop. Because steel is not resistant to high temperature, its strength will be significantly reduced under high temperature environment, leading to deformation and even failure of steel structure members. Therefore, it is necessary to make the fire resistance of the steel factory buildings reach a large limit to avoid immediate collapse in case of fire.
In addition to improving the fire resistance of steel structure workshop, spraying method can also be used to improve the fire resistance of steel structure, change the steel structure and metal structure, and improve the fire resistance and weather resistance of steel structure.
During construction, spraying can also be used to improve the fire resistance of steel structures, and the spraying thickness can be reasonably designed according to the design value. Spraying method is an economical and effective construction method with fast construction speed, especially suitable for steel members with complex shapes. However, this method has some shortcomings such as rough surface and difficulty in cleaning, so it needs to be modified by some design methods during construction.
