针对单片防火玻璃在实际使用中背火面温度高而影响人员疏散的缺点，提出水喷淋保护方案。研究结果表明：在水喷淋保护下单片防火玻璃背火面温度和热辐射通量大大低于无水喷淋保护下的相应数值；快速响应水喷头在高温烟气作用下能够自动启动，可以长时间地保护防火玻璃，而且不会影响到防火玻璃背火面的人员安全疏散。

On account of fine appearance and lucidity of glass, fire-resistant glass has been widely used as architecture exterior materials and fire-resistant compartmentation in modem buildings. Especially, single-pane fire-resistant glass is more widely used than compounding one because of its higher light transmission and less weight in construction. However, single-pane fire-resistant glass can only prevent the spread of fire and smoke, while high temperature and thermal radiation flux on its rear surface may cause a new fire on the protected side. Furthermore, fire-resistant glass is usually quite close to evacuation passage, so it will be harmful to security evacuation. These shortcomings prevent single-pane fire-resistant glass from using in practice. This article describes the experimental study of single-pane fire-resistant glass performance with sprinkler protection. The test setup was introduced in detail, and the test results were discussed. It is showed that the temperature and thermal radiation flux on the protection side of single-pane fire-resistant glass with sprinkler protection are quite lower than those without sprinkler condition. The fast responding sprinkler can automatically spray well-proportioned water and protect certain area. The study of this article may be of benefit to the evacuation calculation in performance-based fire design and engineering application of fire-resistant glass.
