Description
The main advantages of steel structure workshop
1. Light weight, high strength and large span: Although the density of steel structure plant is higher than that of other building materials, the strength is very high. Under the same stress conditions, the steel structure has small self weight and can be made into a long-span structure.Short construction period: the framework of the steel structure plant is mainly fabricated in the factory and transported to the site for installation and assembly, which is convenient for construction.
2. High fire resistance: when the steel surface temperature is within 150 ℃, the strength changes little, and when it exceeds 150 ℃, the strength decreases significantly. Generally, the surface of steel structure will be coated with fire retardant coating to form a layer of protective film to improve the fire resistance of components. Of course, the rational division of fire areas is also very important for the use of fire shutter.
3. Anti seepage and waterproof: rainwater infiltration is mainly through nodes or gaps. In order to achieve anti-seepage and waterproof, it is necessary to use sealing washer at the screw port, then use concealed fixation, and use sealant or welding at the overlap of the plate. It is better to use full-length steel plate to eliminate overlap, and use tight waterproof treatment of abdominal expansion at each node.
4. Sound insulation and heat preservation: the metal roof is filled with sound insulation materials (generally glass wool), or the surface of the metal tile is coated with heat insulation and reflection coating.
5. Ventilation and cooling: the overhead steel structure workshop generally has no super power heating equipment, the personnel are not very dense, and there is no peculiar smell and dust. Roof fan + tower can be adopted. For the steel structure workshop with high structure and large span, the best way is to install a large exhaust fan on the roof to exhaust the air to the outside; Negative pressure is formed in the room; A large amount of fresh air is pressed into the steel structure workshop from around the workshop to form air convection; The effect is very good.
6. Good daylighting: install daylighting panels or glass at specific locations on the roof. Considering the service life of the skylight and its cooperation with the roof panel, the joints must be waterproof.
