世博中心大会堂舞台水消防系统设计

Water fire-fighting system design for the Expo Center

世博中心大会堂(2 600人厅)有两种功能:演出和会议,舞台通过4块移动的台口完成这两种功能的切换,形成两种状态:演出状态和会议状态。根据舞台的两种状态,设计了4套水消防系统,包括:室内消火栓系统、自动喷水灭火系统、大空间洒水系统、舞台雨淋系统;针对移动台口的形式,研究与比选消防系统的控制与连接方案;综合考虑舞台火灾的起火形式及舞台火灾探测方式,设计雨淋系统的喷头布置形式,确定雨淋阀的个数。

Expo Center（2 600 persons capacity） has two functions： performance and conference.By moving four mobile prosceniums,the hall stage can switch between these two modes： performance mode and conference mode.According to two modes,four sets of fire-fighting systems were designed,including： indoor hydraulic system,automatic sprinkler system,large-space sprayer system,stage deluge system.Based on the style of moving prosceniums,the control and connection of fire-prevention system were studied and compared.Grounded on comprehensive consideration of the stage fire styles and detection methods,the sprinkler layout of the deluge system and the deluge valve number were determined.
