摘要
根据《自动喷水灭火系统设计规范》(GB 50084-2017)和相关文献资料,对比中危险Ⅱ级非吊顶地下车库8.4m×8.4m柱网不同排布方式:①井字梁9只标准喷头配水支管变径与不变径布置;②井字梁9只标准喷头与十字梁4只扩大覆盖面积洒水喷头配水支管不变径布置,选用海澄-威廉公式对地下车库自动喷水灭火系统进行水力计算,分析其中利弊,并对各布置形式的最佳适用场所进行推荐。
According to Code for design of sprinkler systems(GB 50084-2017) and related literature, the layout of column network of medium-dangerous grade Ⅱ underground garage(non-ceiling) are compared: ① 9 standard sprinkler nozzles with variable diameter and constant diameter arrangement with grillage beams;② 9 standard sprinkler nozzles with grillage beams and 4 expanded coverage sprinkler nozzles with cross beams with constant diameter arrangement. The Haicheng-William formula is used to calculate the water distribution branch pipe of sprinkler system in underground garage. The advantages and disadvantages are analyzed, and the best places for layout forms are recommended.
