Stairwell

The application of fireproof board in stairwell is an important part of building fire protection design. Its application is not only related to the overall safety of the building, but also directly affects the evacuation efficiency and life safety of personnel when a fire occurs. The following is a detailed analysis of the application of fireproof board in stairwell:

1. Basic characteristics of fireproof board
Fireproof board is a building material with a high fireproof grade, which is mainly made of wood fiber and other auxiliary materials after high temperature and high pressure treatment. It has the following main characteristics:

Excellent fireproof performance: Fireproof board is not easy to burn when it encounters fire, and can effectively delay the spread of fire, buying precious time for personnel evacuation.

High temperature resistance: Even in high temperature environment, fireproof board can maintain its structural stability and will not soften or collapse quickly.

Environmental protection and health: Some fireproof boards are made of environmentally friendly materials, which will not produce toxic and harmful substances and are harmless to the environment and human health.

2. Application of fireproof board in stairwell
Wall closure of enclosed stairwell
Purpose: The purpose of enclosing stairwell is to prevent the spread of fire and ensure the safety of personnel evacuation.

Application method: As a material with good fireproof performance, fireproof board is suitable for wall closure of enclosed stairwell. By choosing fireproof boards with high fireproofing ratings (such as Class A or Class B1), the fireproofing isolation capacity of the stairwell can be effectively improved.
Notes: When choosing fireproof boards, it is necessary to comprehensively consider their fireproofing rating, the use environment, and whether they need to have insulation, sound insulation and other functions at the same time.
Stair treads and handrails
Although fireproof boards are mainly used for wall closures, they may also be used in the production of stair treads and handrails in some designs. This requires that the fireproof boards not only have fireproofing properties, but also have sufficient wear resistance and anti-slip properties.
Door design
The door of the stairwell is also an important part of the fireproofing design. According to the requirements of the specification, the stairwell should be equipped with a Class B fireproof door, and it should be opened in the direction of evacuation. Fireproof boards can be used as part of the fireproof door to improve the fireproofing performance of the door.
