摘要: 搭建室外木结构连廊实验平台开展水幕系统实验,结合建筑的特殊构造,设置不同朝向的水幕喷头,通过两组点火工况的对比,分析水幕启动下不同位置温度及热辐射的变化。结果表明,水幕系统的启动能够有效控制热辐射和烟气蔓延,使得水幕系统后的区段处于相对安全的状态。该系统可为类似工程的消防设计提供参考。

关键词: 木结构连廊, 水幕系统, 热辐射, 烟气蔓延

Abstract: Water curtain system test was carried out for an outdoor wooden structure corridor.Combined with the special structure of the building, water curtain nozzles with different orientations are set. Through the comparison of two groups of ignition conditions, the changes of temperature and thermal radiation at different positions after the starting of water curtain are analyzed.The test results show that the starting of the water curtain system can effectively control the thermal radiation and smoke spread, and make the section behind the water curtain system being in a relatively safe state.The system can provide reference for the fire protection
design of similar projects.

Key words: wood structure, water curtain system, thermal radiation, smoke spread
