Steel structure plant is divided into light steel and heavy steel structure factories
1. Light quality, high strength, and large span: Although the density of steel is larger than other building materials, its strength is very high. Under the same force, the
steel structure is small and can be made into a large span structure.
2. Short construction period: The architecture of the plant is mainly produced in the factory prefabricated. After being transported to the scene, it is installed.
3. High fire prevention: When the surface temperature of the steel is within 150 ° C, its strength changes very small. When the temperature exceeds 150 ° C, its strength decreases significantly. Generally, fireproof coatings are applied to the surface of the steel structure, and a protective film is formed to increase the refractory limit of the component. Of course, the reasonable division of fireproof partitions is also very important for the use of fireproof rolling curtains.
4. Anti -seepage and waterproof: The penetration of rainwater is mainly through nodes or gaps. To prevent seepage and waterproof, it is necessary to use a hidden fixing after using a sealing cushion in the screw port. It is good to use a long board to eliminate the overlap and tight waterproof treatment of abdominal distension at various nodes.
5. Sound insulation: Fill the sound insulation material (usually glass wool) in the metal roof layer, or add insulation reflex coatings to the metal tile surface.
6. Ventilation and cooling: Generally, there is no large power heating equipment without high power, and the personnel are not very dense, and there is no odor or dust. The best steel structure factories with higher architecture and large span are to install a large exhaust ventilator on the roof to discharge outdoors; form a negative pressure in the room; press it around the workshop to a large amount of fresh air in the workshop to form air Flow; the effect is better.
7. Good lighting: Install the lighting board or lighting glass at the specific position of the roof. Considering the service life of the sunroof and the coordination of the roof panel, the connection must be well -proof.
