유리커튼월 수막시스템 분무헤드의 화재 실험 연구

초록

Recently, a curtain wall system was applied to skyscrapers to prevent fire spreading along the vertical direction due tostack effect and outside air flow when a fire breaks out in skyscraper. Conventional sprinklers cannot prevent the spreadof fire to the upstairs areas, which increases the loss of life and property. In this study, a water curtain nozzle that createswider water coverage on the surface of glass and can prevent the spread of fire to the upstairs areas was developed. Thespray pattern of the water curtain nozzle was compared with that of a sprinkler to determine performance of the water curtainnozzle. A fire experiment was constructed on the second floor to verify performance of the water curtain nozzle inpreventing the spread of fire to the upstairs areas. The fire and watering experiment proved that the water curtain nozzleprevented more effectively the spread of fire than the conventional sprinkler. The position of first crack and critical temperatureof fracture were also analyzed using numerical analysis.
