Abstract

Purpose: The purpose of this study is to test the sprinkler performance to protect the wall and ceiling joints of the sandwich panel warehouse in case of fire. Method: Based on the field surveys, test was setup and combustibles were prepared. The sprinkler discharge tests were performed at the corner of the wall and right under the sprinkler head. Results: It has been found that operation of the K-80 closed sprinkler head prevents the ignition of the sandwich panel and therefore no damage to the joints of sandwich panels. To prevent skipping phenomenon, it is necessary to install the sprinkler head from the corner of the wall and to keep a minimum distance of 2.4m and a maximum distance of 3m. Conclution: A Standard Operation Procedure should be prepared to suppress and rescue of fire brigade for a sandwich panel warehouse protected by perimeter sprinklers preventing a ignition of core materials and control fire.

연구목적:본 연구는 화재 시 샌드위치패널 구조 창고의 벽 천장접합부 방호를 위한 스프링클러 성능확인 실험을 목적으로 한다. 연구방법: 현장조사결과를 기반으로 창고의 공간규격과 가연물을 선정하고 벽 코너 및 헤드 직하부에서의 방호실험을 수행하고 결과를 분석하였다. 연구결과:벽 코너 화재 시나리오에 대해서 K-80 폐쇄형 스프링클러헤드의 작동으로 샌드위치 패널의 착화 및 접합부 손상이 방지됨을 확인하였다. 결론:샌드위치패널 심재로의 착화 및 연소방지를 통한 화세제어로 이를 가정한 소방대의 소화 및 구조활동을 위한 표준진압대책이 마련되어야 한다.
