某大型科技文化中心防火设计高度分析

Analysis on fireproof height of a large-scale center of science,technology and culture

针对大型商业综合体中大坡度建筑的高度如何确定,以某大型科技文化中心的防火设计高度分析为例,按照规范的设计原则和目标,从建筑特点、使用功能、消防救援、人员疏散等方面进行综合分析。在满足建筑整体消防安全的情况下,通过设计二层室外平台作为消防车救援场地、人员室外疏散安全出口,合理确定大坡度屋面的屋脊和屋檐高度,按照规范的建筑坡屋面计算建筑高度,确定整体建筑为多层公共建筑,明确了建筑分类,为后期的建筑消防设计提供依据和支撑。

Aiming at how to determine the fireproof height of slope construction in a large commercial area,taking the fire proof height of a large-scale center of science,technology and culture as the example,a comprehensive analysis of architectural features,functions,fire rescue and personnel evacuation was carried out with the principle and target from the code.Under the circumstance of ensuring the safety of whole building,the terrace on second floor was designed as for fire truck rescue site and human evacuation exit.The ridge and eaves height of large slope roof were determined reasonably,and the building height was calculated according to the code.The building was identified as multi-storey public buildings,and the classification of buildings is defined.It might provide reference and support for the fire protection design of this kind building.
