门墙组合构件的耐火性能分析

Fire resistance analysis of the combined member of the wall and the door sets

将防火墙和防火门这两个子系统视为一个组合构件,从整体角度来考察该组合构件的耐火性能。在防火墙子系统的背火面、防火门子系统的门扇背火面、两个子系统的结合处设置测温点。实验进行180min,记录不同时刻各测温点的温度数据。实验结果表明:所测试的系统能够满足耐火极限的要求,安全裕量较大。建议加强防火墙与防火门子系统结合处的设计,保证其力学强度。

The subsystems of the fire wall and the fire door were taken as a total system and the fire performance of this system was tested.The test spots were set at the back of the wall,the back of the door and the back of the juncture.The system was tested for 180 minutes and the temperature of test spots at different time was recorded.The results showed that this system can fit the requirement of fire endurance and the safety margin was big.Suggestion on enhance the design of juncture of fire wall and fire door was put forward to make sure the mechanical strength.
