剧场类大空间建筑由于其特殊的使用功能而具有不同于普通民、商用建筑的的空间特点,内部尤其观众厅缺少明确的防火分区,具有极大的火灾隐患。此外,在其使用过程中人员密度大且人们多专注于活动本身,一旦发生火灾疏散起来十分困难,容易对人员安全造成极大威胁,后果严重。文章从剧场类大空间的空间特点、火灾隐患因素、火灾特征等方面逐步展开叙述,并讨论了现有的剧场观众厅的防排烟措施。
Because of its special use function, the large-scale theater building has the characteristics of space different from ordinary citizens and commercial buildings. The interior, especially the auditorium, lacks a definite fire protection partition and has a great fire hazard. In addition, during the process of using it, the density of people and the people’s concentration on the activities themselves are very difficult to evacuate and threaten the safety of personnel. The consequences are serious. The article begins with the narration of space characteristics, fire hazard factors and fire features in the large space of theater, and discusses the smoke control measures in the auditorium of theaters.
