| 中文摘要: |
| 针对双层玻璃幕墙实际应用中的消防问题,采用全尺寸火灾实验的方法对火焰和烟气在双层幕墙结构中的传播进行了分析研究。在建立实体实验模型时采用同工程设计和实际构造相同的双层玻璃幕墙,并按实际尺寸搭建了一座2层的楼房模拟客房床垫中央着火、客房床垫角落着火和客房整体失火3种工况,并对火源热释放速率、幕墙玻璃内外侧温度、火焰和烟气运动过程进行了测量和观测,得出了火焰传播过程和烟气在幕墙夹层内运动特征及双层玻璃幕墙结构临界破碎温度、破碎时间等耐火性能特性。 |
| 英文摘要: |
| Describes the fire protection challenge brought by the double skin facade and a study of the fluence of this kind of facade on the potential of vertical fire spread.According to the actual size and structure,the two layers building and double skin facade were set up,the full scale fire tests were conducted and three cases were simulated: the center burn of mattress in the guest room;on the corner burn of mattress;another case on the whole burn of the guest room,fire heat release rate,outside and inside temperature of double skin facade were measured and smoke movement was observed.Based on the results,it is found that there was a potential of fire spread via the cavity of the double skin facade,and the fire resistance characteristics on the double skin facade,for example the critical breaking temperature and breaking time etc,were given. |
