What should be paid attention to in the roof design of steel structure workshop?
The steel structure manufacturer of the factory building gives you a detailed introduction – the matters needing attention in designing the roof of the steel structure factory building.
1. Seepage prevention
Prevent precipitation from infiltrating into the metal roof panel of the steel structure factory workshop from the outside. The precipitation is mainly based on the lapping gap or node into the metal roof. In order to achieve the effect of seepage prevention, it is necessary to use the embedded fixation after using the sealing gasket at the screw opening. The lap joint of the plate should be treated with sealant or welding. It is better to use a full-length plate to remove the lap joint. At various nodes, it is necessary to have a tight waterproof treatment.
2. Fire protection
In case of fire, the metal roofing materials of the steel structure workshop will not burn, and the flame will not pass through the metal roof panel.
3. Wind pressure resistance
The metal roof panel of the steel structure workshop will not be pulled off by the negative wind pressure to resist the local large wind pressure. The wind resistance performance is related to the bonding force between the metal roof panel and the fixed base, and the density of the fixed base.
4. Sound insulation
Block the sound from outside to inside or from inside to outside. The metal roof layer of the steel structure workshop is filled with sound insulation materials, and the sound insulation effect is shown by the sound intensity difference between the two sides of the metal roof layer. The sound insulation effect is related to the density and thickness of the sound insulation material. It should be noted that sound insulation materials have different effects on sound insulation at different frequencies.
5. Ventilation
Gas exchange is carried out indoor and outdoor in the steel structure factory building. Provide ventilation holes on the metal roof.
6. Moistureproof
Avoid condensation of water vapor in the metal roof bottom layer and metal roof layer, and drain the water vapor from the metal roof layer. The solution is to fill the metal roof layer of the steel structure workshop with thermal insulation cotton, lay a waterproof membrane on the bottom plate of the metal roof, and have ventilated nodes on the metal roof panel.
