Smoke wall is a common passiv fire protection facility in buildings, its main function is to limit the flame and smoke in the burning area when the fire occurs, reduce the spread of the fire, and improve the evacuation time. The smoke wall is usually composed of metal or non-metal materials, and has certain fire protection characteristics, which can effectively isolate the fire space and prevent the spread of the fire.

The fire protection characteristics of the smoke baffle wall mainly include the following aspects:

1. High temperature resistance: the smoke wall is usually made of materials with high temperature resistance, which can withstand high temperature thermal radiation and flame attack in the event of fire, and is not easy to deformation, fall off, etc., to ensure the integrity and stability of the vertical wall.

2. Smoke insulation performance: The main function of the smoke wall is to isolate the burning area and non-burning area, prevent the smoke from spreading to the personnel evacuation channel and escape channel, and ensure the safety of personnel. The vertical wall of the smoke baffle has good smoke insulation performance, which can effectively prevent the spread of smoke and reduce the harm caused by smoke to personnel.

3. Tensile performance: the vertical wall of the smoke shield requires a certain tensile performance, which can withstand the thermal expansion and contraction caused by the fire and the structural stress, maintain the stability and strength of the vertical wall, and is not easy to damage and collapse.

4. Heat insulation performance: the smoke wall also has a certain heat insulation performance, which can reduce the impact of thermal radiation on the inside and surrounding structure of the wall, slow the spread of the fire, and reduce the degree of fire harm.

5. Durability: The smoke baffle wall requires a long service life in the use process, can withstand long-term wind and rain and environmental erosion, and maintain good fire protection effect and appearance quality.

To sum up, as an important passiv fire protection facility in buildings, the smoke baffle hanging wall has excellent fire protection characteristics, which can effectively isolate the fire space in the event of a fire and ensure the safe evacuation of personnel. Therefore, in the architectural design and construction, the fire performance requirements of the smoke baffle wall should be fully considered, and the appropriate material and structural design should be selected to ensure that it plays a stable, reliable, safe and effective role.
