开放空间防火疏散设计研究——关于国标图集《建筑设计防火规范》图示-5.5.17图示7的探讨

Study on Fire Evacuation Design of Open Space:Discussion on Figure 7 of Code for Fire Protection Design of Buildings

“45°规则”是建筑开放空间疏散设计中的重要规则,与美国消防安全协会(NFPA)倡导的“半对角线法”相比各有优劣。掌握《建筑设计防火规范》图示中的“45°规则”,并合理应用该规则,是保证开放空间疏散设计的关键。

"45° rule" is an important rule in the evacuation design of building open space.Compared with the "semi diagonal method" advocated by the American Fire Safety Association,each has its own advantages and disadvantages.The key to ensure the evacuation design of open space is to master the "45°rule" in the figure of Code for Fire Protection Design of Buildings and reasonably apply the rule.
