1. Wind resistance: it can resist the local atmospheric pressure, and the steel structure workshop is not easy to be broken by the negative pressure. The wind resistance energy is related to the bearing force and relative density of steel column and vertical pole.
2. The practical effect of sound insulation and noise reduction: prevent the noise from being transmitted from outside to inside or from inside to outside. Sound absorbing materials (usually used as thermal insulation materials) are added to the floor of steel structure workshop. The actual effect of sound insulation and noise reduction is expressed by the shell of sound intensity difference on both sides of the floor. The actual effect of sound insulation and noise reduction is related to the relative density and thickness of sound absorption materials. It should be noted that sound-absorbing materials have different isolation effects on different frequencies of sound.
3. Dampproof: to avoid precipitation from the outside into the metal roof. Precipitation is mainly based on the steel lap gap or connection point into the steel structure plant. In order to achieve the function of waterproof layer, it is necessary to coat the sealing gasket at the screw mouth, fix it with built-in type, and use sealant or electric welding at the steel bar lap joint of the plate. The lap joint of reinforcement shall be removed with long plate as far as possible, and each connection point shall be moistureproof.
4. Lightning protection: lead the lightning to the road to avoid the lightning penetrating the roof of the steel structure workshop into the room.
5. Lighting: improve indoor lighting according to panoramic skylight in broad daylight to save energy. When laying daylighting tiles or laminated glass in special parts of metal roof, the service life of panoramic skylight should be coordinated with metal roof, and the load should be solved at the junction of panoramic skylight and steel structure of steel structure workshop.
