某影视基地改造中的消防问题分析

Analysis on fire safety problems during the renovation of the film and television base

分析某影视基地消防改造过程中遇到的安全疏散、耐火极限方面的问题,结合工程实际,从增设安全出口、控制火灾荷载、提高构件耐火性能等方面提出相应的解决方案。设置不同位置起火、自动喷水灭火系统和机械排烟系统不同运行情况的火灾场景模拟火灾发展,并设置相应的疏散场景,评价改造措施的有效性。根据模拟结果提出改设乙级防火门、限制人数等措施保障消防安全。

Combined with engineering practice, safe evacuation and fire endurance of a fihn and television base during fire safety renovation were analyzed in the fields of additional security ex it, fire load control and improving the component fireproof per formanee for the solutions. Fire scenario simulation was applied to study the fire development by setting different factors inclu ding fire location, sprinkler system running condition and me- chanical exhaust system running condition. Evacuation scenario was conducted for evaluating the effectiveness of the renovation According to the simulation results, the use of type-b fire door and population limits could be available for fire safety.
