Wanxin Fire
1. Steel smoke-blocking vertical wall refers to the smoke-proof isolation measures installed vertically under the ceiling, beam or ceiling of the building, which can form a certain smoke storage space in the event of a fire. During a fire, the steel smoke-retaining vertical wall can effectively flow the smoke under the ceiling and establish a smoke storage bin that is conducive to smoke exhaust. The height requirement shall not be less than 500mm. It is suitable for large spaces such as large shopping centers, office buildings, and warehouses. 2. The steel smoke barrier is made of non-combustible materials, and the fire resistance limit is not less than 0.5h. When it is used under the suspended ceiling, the smoke-shielding vertical wall installed vertically below the station under the suspended ceiling shall be made of transparent silk fire-resistant glass, and the height shall be 500mm below the suspended ceiling. . Not only can it meet the needs of the smoke and fire protection function, but also because of its good air permeability, the vertical wall of the smoke shield is not less than 2.3m from the ground.
