1概述在工程实际应用中,中庭共享空间周边设置环廊,通过环廊将相邻商业区域与中庭联系在一起,形成高大复杂的连通空间的设计形式越来越多(如室内步行街)。现行规范并未对中庭、环廊及相邻商业形成的区域防排烟设计进行要求,防火设计、消防审核时对该类型区域无依据可遵循。
1 Overview In practice, the atrium is set around the shared space of the atrium, and the adjacent commercial area is connected with the atrium through the perimeter porch. As a result, there are more and more forms of design for tall and complicated connected spaces (such as pedestrian shopping streets). The current norms do not require the design of smoke control and smoke evacuation zones in atriums, corridors and adjacent commercial areas. Fire safety design and fire protection audits can not follow this type of area.
