샌드위치패널은 건축물의 내 외벽 및 지붕구조에 사용되며 양면의 불연성재료와 단열용 심재로 구성된 복합자재이다. 뛰어난 단열성능과 경량 및 시공의 우수한 특성 대비 화재 시 패널간 결합부위를 통해 화염이 내부로 유입되어 심재가 쉽게 용융되며 급격한 화염확산으로 인명 및 재산피해를 발생시킨다. 현행 건축법은 건축물 마감재료에 대하여 소규모 시험편에 대한 화재시험방법으로 연소성능을 파악하며 규정한 성능기준에 합격한 제품을 사용하도록 한다. 외벽 마감재료의 경우 불연 준불연 성능확보 재료를 사용하거나 화재확산방지구조를 설치하도록 규정한다. 본 연구는 외벽 마감재료에 국한되어 적용하고 있는 화재확산방지 구조를 샌드위치패널 건축물에 적용하여 수평 수직 화재확산의 위험성의 차이를 확인하고자 하였다. 이에 샌드위치패널에 대하여 ISO 13784-1 시험방법을 통한 실물화재실험과 금속구조물을 이용하여 패널간 화염확산을 차단하는 시공을 통해 화염확산방지 적용 여부에 대한 연소거동과 그 효과를 측정하였다. 실험 결과 패널 조인트 부위의 화염확산방지구조 시공은 패널 내부의 화염확산을 지연하며 이에 따른 플래시오버 시간이 지연되어 복합자재 건축물의 화재안전확보에 중요한 요인으로 작용될 수 있음을 확인하였다.
A sandwich panel is a composite material composed of a double-sided noncombustible material and insulation core which is used in the inner, outer walls, and roof structure of a building. Despite its excellent insulation performance, light weight and excellent constructability, a flame is brought into the inside of the panel through the joint between the panels, melting the core easily and causing casualties and property damage due to the rapid spread of flame. The current Building Law provides that the combustion performance of finishing materials for buildings should be determined using a fire test on a small amount of specimen and only a product that passes the stipulated performance standard should be used. This law also provides that in the case of finishing materials used for the outer walls of buildings, only materials that secured noncombustible or quasi-noncombustible performance should be used or flame spread prevention (FSP) should be installed. The purpose of this study was to confirm the difference between the dangers of horizontal and vertical fire spread by applying FSP, which is applied to finishing materials used for the outer walls of buildings limitedly to a sandwich panel building. Therefore, the combustion behavior and effects on the sandwich panel according to the application of FSP were measured through the construction to block the spread of flame between the panels using a full scale fire according to the test method specified in ISO 13784-1 and a metallic structure. The construction of FSP on the joint between the panels delayed the spread of flame inside the panels and the flash over time was also delayed, indicating that it could become an important factor for securing the fire safety of a building constructed using complex materials.
