钢质防火门失去耐火完整性问题分祈及改进措施的研究

摘要

Analyzed the reasons of the fire resistant steel doorsets loss of fire integrity in this paper. Showed the deformation mechanism of the fire resistant steel doorscts in fire resistant test, and studied the problem of fire integrity of the fire resistant steel doorsets. The tests proved that the improvement could improve the fire integrity of the fire resistant steel doorsets.%本文对耐火试验中铜质防火门失去耐火完整性的原因进行了分析．提出了铜质防火门耐火性能试验中门扇的变形机理，并对如何改进铜质防火门的耐火完整性进行了研究。经试验证明，改进措施很好地提高了钢质防火门的耐火完整性能。
