多舱体系钢结构变电站附加防火层耐火性能试验研究

open access: yesJianzhu Gangjiegou Jinzhan
为保证多舱体系变电站的钢结构预制舱单元在主变压器火灾下的安全性,提出了一种以蒸压轻质混凝土板作为围护材料的附加防火层构造;该构造基于建筑工业化的发展背景,不仅可在工厂预制,现场施工亦简单快捷。基于碳氢化合物火灾升温曲线,对既有多舱体系变电站所采用的复合墙体及所提出的附加防火层构造进行了时长为3 h的受火试验;其中,5个附加防火层试件的设计考虑了重复受火、钩头螺栓锚固长度、板厚、干密度等级、板材连接方式等参数的影响。结果表明,由于热桥效应,复合墙体试件中的构造钢柱所对应的背火面测点温升在107 ...
