초록

랙크식 창고 내에는 화재하중이 높은 물품이 수직으로 조밀하게 적재되어 있어 창고의 내부에서 화재가 발생되는 경우 현재의 스프링클러설비에 의해 유효하게 소화되기 어렵다. 이에 본 연구에서는 실물 규모의 랙크 구조물을 구축하고, 구조물 내부의 스프링클러헤드 종류 및 배치에 따른 화재실험을 통해 스프링클러설비에 의한 소화유효성을 확인하였다. 본 연구를 통하여 랙크식 창고의 내부의 화재를 유효하게 진압하기 위해서는 방수량 115 LPM 이상의 스프링클러헤드를 사용해야 하며, 동 스프링클러헤드를 높이 기준이 아닌 랙크 각 단마다 설치해야하고, 각 단의 가연물더미의 대각선 모서리 위치에 설치될 필요가 있다는 것을 알 수 있었다.

In rack-type warehouses, it is difficult to extinguish fires effectively using sprinkler systems because high fire load commodities are stacked vertically and densely. In this study, an actual size rack structure was constructed and the effectiveness of the fire extinguished by the sprinkler system was confirmed through fire tests according to the type and arrangement of the sprinkler head in the rack structure. Through this study, to effectively suppress fires in rack-type warehouses, it is necessary to use sprinkler heads with a volume of more than 115 LPM and sprinkler heads need to be installed at the diagonal corner positions of the commodities of each rack.
