In recent years, the issue of fire safety in high-rise buildings has become a major concern, especially with the widespread use of glass aluminum curtain walls. When exposed to fire or extreme heat, these structures are prone to shattering, leading to large-scale breakage and rapid fire spread. This phenomenon, known as the "fire wind effect," can pose serious threats to both human lives and property. To address this risk, it is essential to implement proper fire protection measures during the design and construction phases.
Based on practical experiences from both domestic and international applications of aluminum curtain walls in high-rise buildings, and lessons learned from past fire incidents, it has been found that using non-combustible materials such as rock wool, mineral wool, glass wool, and aluminum silicate in the gaps between glass panels and window frames is highly effective in preventing fire propagation.
The general requirements for fire protection in glass aluminum curtain walls include:
1. Non-combustible materials must be used as fillers in window walls and wall sections. If the outer surface of a non-combustible structure has a fire resistance rating of at least 1 hour, then hard-burning materials may be used as filling materials, provided they meet other safety standards.
2. On the outer edge of each floor of the glass curtain wall, where there are no window partitions or window curtains, solid non-combustible skirt walls with a fire resistance rating of at least 1 hour and a height of not less than 0.8 meters should be installed.
3. The gaps between the glass curtain wall and each floor slab or partition wall must be filled with non-combustible materials to prevent the spread of fire through these openings.
By following these guidelines, building designers and engineers can significantly enhance the fire resistance of glass aluminum curtain walls, ensuring greater safety for occupants and reducing the risk of catastrophic fire damage. It's crucial to stay updated with the latest fire safety codes and best practices to adapt to evolving building technologies and environmental challenges.
