摘要： 为了评价建筑外火灾对室内自动喷水灭火系统以及防火玻璃的影响，搭建试验平台，开展24次室外火灾条件下水对防火玻璃完整性影响测试。研究表明，24次试验中自动喷水灭火系统均启动，并导致防火玻璃破裂甚至完整性丧失。系统感温元件破裂温度在84~87 ℃，远高于标称温度68 ℃。不同厚度玻璃破裂行为不同，5、6、8、10 mm玻璃破裂后脱落，而12 mm和15 mm玻璃破裂后因厚度方向未贯穿未脱落。为保障建筑外窗耐火完整性，需要综合考虑自动喷水灭火系统中洒水喷头的布置、感温元件的测试方法以及防火玻璃的选用。

Abstract: This study investigates the impact of exterior building fires on both the internal automatic sprinkler system and fire-resistant glass. An experimental platform was developed, and 24 tests were conducted to assess the influence of water on the integrity of fire-resistant glass under simulated outdoor fire conditions. The findings reveal that in all 24 tests, the automatic sprinkler system was activated, and the fire-resistant glass's integrity was compromised. The temperature sensing elements ruptured at temperatures ranging from 84~87 ℃, significantly exceeding their nominal activation temperature of 68 ℃. The study also observed distinct rupture behaviors based on glass thickness: 5, 6, 8, and 10 mm glass panes shattered and detached upon rupture, whereas 12 mm and 15 mm glass panes remained intact as the rupture did not penetrate the glasses. To ensure the fire integrity of building external windows, it is necessary to comprehensively consider the layout of sprinkler heads in automatic sprinkler systems, the testing methods of temperature sensing components, and the selection of fire-resistant glass.
