某石膏板吊顶高大空间火灾试验研究

Experimental study on the fire of a large space with gypsum board ceiling

通过对一起带石膏板吊顶高大空间建筑火灾的事故调查,展开调查走访、现场勘验,针对火灾起火部位无法确定的问题,开展1∶1全尺寸火灾试验研究,得到与火灾现场一致的燃烧痕迹特性,最终确定火灾部位为吊顶下方。总结该类建筑火势蔓延的特殊规律,为火灾调查及灭火救援提供参考。

Through fire investigation on a large space building with gypsum board ceiling, launched a series of investigation and on-site inspection. As the fire origin was difficult to identify, the 1 ： 1 full-scale fire test was carried out and the combustion trace was consistent with that on the scene, and the fire origin was finally identified as under the ceiling. The special rules of fire spread in the building were summarized, which could provide references for fire investigation and fire fighting and rescue of similar buildings.
