自动喷水灭火系统设计.doc

中文摘要 自动喷水灭火系统作为一种建筑消防设施，已经得到广泛应用，大量的工程实践也已经证明了其灭火、控火的高效性，但由于一些历史原因及人们长期以来对建筑消防的固有观念，使得它在建筑消防减灾0范虽给设计施工提供了可执行的依据，但规范本身还存在着一定的缺陷，削弱了自动喷水灭火系统的灭火性能。 本文在分析研究国内外大量的相关数据及文献的基础上，结合工程实践经验,从安全性、经济性、合理性的原则出发，强调了自动喷水灭火系统在建筑消防中不可替代的地位。同时，对规范中的相关条文及工程实践中难以解决的问题，提出了自己的观点，使之不断完善。 关键词：自动喷水灭火系统 消防 自动报警 喷淋泵 ABSTRACT As fire protection services for building, the sprinkler systems have been extensively used, lots of engineering practices have also proved that these systems have high efficiency on fire-extinguishing and fire-controlling. But some historical reasons and some original concepts about the fire protection for building caused the guiding place of the systems in fire protection for building not to be established Moreover, each kind of related standard although has provided the basis to the design construction which may carry out, but standard itself also has the certain flaw, weakened the automatic deluge system extinguishment characteristics. This article studies the domestic and foreign massive correlation data and in the literature foundation in the analysis, the union project experience, from the security, the efficiency, the rational principle embarked, emphasized the automatic deluge system the status which could not be substituted in the construction fire prevention. At the same time, the question which solves with difficulty to in the standard related article and the project practice, proposed own viewpoint, cause it unceasingly to consummate.
