摘要:国内建筑业发展非常迅速,随着《高层民用建筑设计防火规范》(以下简称《高规》)的更新及新《自动喷水灭火系统设计规范》(以下简称《自喷规范》)的出台,对高层建筑消防给排水设计的要求也日趋严格。特别是近年来,各省、市都先后开始实施建筑工程图审查制度,其审查的主要依据为2000 年颁布的《工程建设标准强制性条文》,《强制性条文》所规定的各项条款是设计当中必须遵循的硬性要求。

Abstract: the domestic construction industry is developing very fast, with the code for fire protection design of high civil buildings (hereinafter referred to as the high rules ") and the renewal of the new "automatic sprinkler system design rules" (hereinafter referred to as the spray from the standard "), the promulgation of the fire water supply and drainage design of high-rise building requirements are strictly. Especially in recent years, province and city are successively began to carry out the system of review of architecture engineering drawings, the review of the main basis for 2000 years "issued by the engineering construction standards mandatory provisions", "the mandatory provisions of the regulations of the terms is design must be in accordance with the requirements of the rigid.

1 在高层建筑内应控制使用双阀双出口消火栓代替两组单阀消火栓
《高规》规定“同层相邻两个消火栓的水枪的充实水柱达到被保护范围内的任何部位。”在某些条形高层建筑中,其端部是否可以采用双阀双出口消火栓,从而省去1 组单阀消火栓的设置呢?虽然在中国建筑工业出版社出版的《给水排水设计手册》(第二版) 中提出“在每层楼的端部可采用双阀双出口消火栓”,但是《高规》中明确规定“十八层及十八层以下,每层不超过8 户、建筑面积不超过650m2 的塔式住宅,当设两根消防竖管。有困难时,可设一根竖管,但必须采用双阀双出口消火栓。”且以强制性条文的形式予以规定。因此,在设计中我们应该力求避免出现这种情况。
2 正确计算消火栓充实水柱长度,合理布置消火栓
《高规》规定“消火栓的水枪充实水柱应通过水力计算确定,且建筑高度不超过100m 的高层建筑不应小于10m;……
