If the roof of the steel structure factory building is not designed properly, it will have a significant impact on the later stage. Fire prevention is essential, followed by anti leakage, as well as being able to bear weight and not affect indoor ventilation and lighting. When installing, the materials should be checked first before installation. If any defects are found during installation, they should be promptly repaired.
Key points of roof design for steel structure factory building
Fire prevention: Fire prevention is a key issue that needs to be paid attention to during the construction process of steel factory building. When a fire occurs, it is necessary to ensure that the roof materials do not catch fire. Generally, metal roofing materials do not burn, and flames do not penetrate the metal roof panels.
Seepage prevention: mainly to prevent rainwater from seeping into the metal roof panel from the outside, especially in rainy seasons, anti-seepage work must be done well. Rainwater usually enters metal roofs through overlapping gaps or nodes.
Load bearing: withstand construction loads, rainwater, dust, snow pressure, and maintenance loads. The load-bearing performance of metal roof panels is related to the cross-sectional characteristics of the panel type, the strength and thickness of the material, the force transmission method, and the spacing between purlins (secondary purlins).
Insulation: prevents the transfer of heat on both sides of the metal roof, ensuring stable indoor temperature. The insulation function is achieved by filling insulation material under the metal roof panel, and the insulation effect is expressed in U value, unit: WM2K.
Daylighting: Improving indoor lighting through skylights during the day, saving energy. When arranging daylighting panels or glass at specific locations on metal roofs, the service life of skylights should be coordinated with the metal roof panels, and waterproofing treatment should be done at the connection between skylights and metal roof panels.
Anti avalanche: This is a problem that everyone easily overlooks, so it is necessary to set up snow barriers on metal roofs in snowy areas to prevent sudden sliding of snow.
Installation method for roof of steel structure factory building
1. The installation and maintenance of steel structure factory roofs are generally carried out on sunny days. Installation personnel are arranged to inspect and reinforce the defective lock joints, nails, and other parts of the roof. If necessary, they are replaced. For areas prone to water accumulation, edge plates should be added for modification.
2. The effectiveness of color steel plate roof waterproofing largely depends on the on-site construction experience and professionalism of the installation unit. It is necessary to require technical personnel to be familiar with the design and structure of prefabricated houses, the construction process and installation steps of different materials, as well as the advantages and disadvantages of various waterproof material processes and practical application points, to maximize strengths and avoid weaknesses, optimize combinations, and develop reasonable construction plans and related technical measures based on the actual situation of the site project.
3. After the installation and construction are completed, inspect the roof of the entire steel structure factory buildings. If there are any defects, make up for them in a timely manner, clean the construction and installation site of the roof, and notify relevant personnel to come for inspection. The inspection methods include flushing experiments or inspection after rain.
