In recent years, most factories have adopted steel structures.What are the advantages of steel structures? Let's take a look at the major factories building factories with this material.1. Light weight, high strength and large span Although the density of steel is greater than that of other building materials, its strength is very high.Under the same stress condition, the steel structure is light in weight and large in span.2. Short construction period: The main components of the factory are prefabricated in the factory.After being shipped to the site, it is easy to install.3. High refractoriness: When the surface temperature of the steel is within 150°C, the strength changes little.When the temperature exceeds 150°C, the strength decreases significantly.Fire retardant coatings are often used on the surface of steel structures to form a protective film and improve the fire resistance of parts.Of course, the reasonable division of fire compartments is also very important for the use of fire shutters.4. Anti-seepage and waterproof: The infiltration of rainwater is mainly carried out through nodes or gaps.To prevent leakage and waterproofing, concealed fixing should be used after the use of sealing washers at the screw ports, and sealant or welding treatment should be used at the joints of the plates.It is best to use longboards to eliminate overlapping joints and expand at various joints for strict waterproofing.5. Sound insulation: The metal roof layer is filled with sound insulation material (usually glass wool), or a heat reflective coating is applied on the surface of the metal tile.6. Ventilation and cooling: It is usually a high-architecture workshop without super-power heating equipment, the personnel are not very dense, and there is no smell or dust.Roof fan + gas building can be used.For the steel structure with high structure and large span, it is best to install a large exhaust fan on the roof to form indoor negative pressure; inject a large amount of fresh air from around the workshop to form air convection, and the effect is very good.Seven, good lighting: Lighting panels or lighting glass are installed in specific locations on the roof.Considering the service life of the skylight and the coordination of the roof, the joint must be waterproof.
