Once a fire occurs, it not only causes enormous casualties and property damage but also severely impacts social order. Fire-resistant glass, as a material that combines fire resistance with architectural aesthetics, has been widely used in the construction industry.

However, in some special scenarios, conventional fire-resistant glass is insufficient to meet fire protection needs, such as in some large public buildings, industrial buildings, and high-rise buildings. Therefore, in order to solve the fire protection requirements in the above scenarios, this invention provides a segmented dynamic control method for enhanced wind pressure of fire-resistant glass.
