通过工程实例介绍马戏表演场这种特殊形体大空间建筑的防排烟系统的设计。利用消防性能化对火灾场景进行模拟计算分析,根据计算结果指导防排烟等系统的设置。采取舞台区域安装雨淋系统、观众厅安装大空间智能型主动喷水灭火系统、座椅进行阻燃处理等措施,为室内人员的安全疏散提供保障。 Through the example of the project, we introduce the design of the smoke control and smoke exhaust system of this special form and large space building. The use of fire performance of the fire scene to simulate the calculation and analysis, according to the calculation results guide smoke exhaust system settings. Take the stage area to install the rain system, auditorium installation of large space intelligent sprinkler system, fire retardant seat treatment and other measures for the safety of indoor personnel to provide protection.
