摘　　要：通过工程实地走访及设计调查,发现自动喷水灭火系统实施中,障碍物下增设喷头布置不满足规范的情况广泛存在。造成这种情况的原因在于自动喷水灭火系统规范相关条文规定的安装距离长度无法满足安装施工要求。通过查阅国内外相关标准与文献、分析与计算,提出可适当增大喷头溅水盘距离障碍物的距离。现有规范使用情况下,提出采用边墙型喷头以减小喷头溅水盘与障碍物的距离。It is found that the arrangement of sprinkler under obstruction does not conform the standard in the implementation of sprinkler system through the project field visit and design investigation. The reason is found that the installation distance stipulated is not satisfied installation requirements in the code for design sprinkler system. It is suggested that the distance between sprinkler deflector and the obstruction can be increased appropriately by referring to relevant literature, analysis and calculation. The side-wall sprinkler is proposed to reduce the distance between the sprinkler deflector and the obstruction during the existing data.
