摘　　要：为研究建筑内常见的电缆桥架在不同位置下对一种新型仓储类喷头(CMSA喷头)布水效果的影响规律,设置电缆桥架与喷头间不同的水平距离、垂直距离的工况开展实验研究。通过控制单一变量的方法研究了20 cm宽桥架与CMSA喷头不同位置关系时对该喷头布水效果的影响规律,并同ESFR喷头在相同条件下的实验结果进行对比,发现CMSA喷头对障碍物的敏感度低于ESFR喷头。20 cm宽桥架在距离CMSA喷头水平0~45 cm、垂直15~45 cm的范围内均能对喷头的布水效果产生显著影响。The experimental study was conducted in order to study the effect rules of water distribution efficiency of common cable bridge on a new type of storage type sprinklers(CMSA)in the buildings under different locations.Scenarios with different horizontal distance and vertical distance from the cable bridge to the sprinklers were set to carry out the experiments.Using the method of controlling the single variable,the experiments made a research on the influence law of water distribution efficiency,the influence that the20cm wide bridge has on CMSA sprinklers at different horizontal distance and vertical distance.Besides,the ESFR sprinkler under the same experimental conditions was analyzed comparatively.The results were that the sensitivity of the CMSA sprinkler to bridge obstructions was lower than the ESFR sprinkler.And20cm wide bridge from the CMSA sprinkler with a horizontal distance ranging from0to45cm and a vertical distance ranging from15to45cm had a significant effect on the water distribution effect.
