摘　　要：针对目前大型综合性商业建筑拟采用钢化玻璃作为防火分隔物的使用需求,通过建立实体试验模型研究在自动喷水冷却系统保护下钢化玻璃作为防火分隔物有效性,并进而提出可行的自动喷水冷却系统保护方案。研究结果表明:快速响应型洒水喷头在高温烟气作用下可及时启动并对玻璃进行冷却保护,使钢化玻璃完整性未受到破坏,且玻璃背火面温度和热辐射强度均小于无水系统冷却保护的情况。Aiming at use requirement on toughened glass as fire barrier in the large-scale comprehensive commercial buildings,full scale fire tests were conducted to check the effect of toughened glass protected by water sprinkler as fire barrier,thereby a feasible sprinkler cooling system protection scheme was proposed.Based on the results,it was found that fast response sprinkler in high temperature smoke can timely start and cool glass to prevent the damage of the toughened glass integrity,and the temperature and thermal radiation intensity of glass back-fire surface were descreased as compared to the cases without sprinkler cooling system.
