본 발명은 내화성능이 개선된 샌드위치 패널의 시공구조에 관한 것으로, 더욱 상세하게는 건축물의 내,외벽 및 지붕 등에 시공되는 샌드위치 패널 접합부의 내화성을 향상시킨 내화 성능이 개선된 샌드위치 패널의 시공구조에 관한 것이다.The present invention relates to a construction of a sandwich panel with improved fire resistance, and more particularly, to a construction of a sandwich panel with improved fire resistance, which improves the fire resistance of a sandwich panel joint to be constructed on the inner, outer walls, and roofs of a building. It is about.

주지하는 바와 같이 샌드위치 패널은 양면 도장된 강판 사이에 우수한 단열 성능을 가지는 폴리스티렌폼(Expanded poly-stylene foam), 우레탄폼(Poly-urethane foam), 그라스울(Glass wool) 등의 단열재를 내장시킨 합성복합재로써, 건설현장의 인력난, 자재난의 극복 및 건식공법의 적용으로 인한 시공의 편리성을 가져 사용량이 증가하고 있는 건축용 자재이다.As is well known, the sandwich panel is a composite composite material in which insulation materials such as expanded poly-stylene foam, polyurethane foam, and glass wool have excellent insulation performance between the coated steel sheets. As a result, it is a building material that has increased in use due to convenience of construction due to overcoming manpower shortages, material shortages in construction sites, and application of a dry method.

이러한 샌드위치 패널은 공업용 건축 및 창고시설 등의 용도뿐만 아니라 주택 및 냉동 창고, 정밀기계 공장, 전자반도체 공장, 항온항습실 등 그 사용이 확대되고 있는 실정이다.Such sandwich panels are being used not only for industrial construction and warehouse facilities, but also for housing and freezing warehouses, precision machinery factories, electronic semiconductor factories, and constant temperature and humidity rooms.

이와 같은 샌드위치 패널을 도1 및 도2에 도시하였다.Such a sandwich panel is shown in FIGS. 1 and 2.

이에 도시된 바와 같이 샌드위치 패널(100)은 일정 두께를 가지는 강판의 양면에 아연이 도금된 아연도금강판(101)을 제작하고, 이들 아연도금강판(101) 사이에 폴리스티렌폼, 우레탄폼 또는 그라스울 등의 불연성 심재(102)를 충진하며, 다수개의 샌드위치 패널(100)이 연속적으로 조립되도록 샌드위치 패널(100)의 일측 단부에 심재(102) 보다 아연도금강판(101)의 길이를 더 돌출시킨 접합부(103)를 형성하고, 이에 다수개의 리벳(104)이 삽입되도록 통공(105)을 형성한다.As shown in the drawing, the sandwich panel 100 fabricates zinc plated galvanized steel plates 101 on both sides of a steel plate having a predetermined thickness, and polystyrene foam, urethane foam or glass wool, etc., between the galvanized steel sheets 101. The non-combustible core material 102 is filled, the joint portion protruding the length of the galvanized steel sheet 101 more than the core material 102 at one end of the sandwich panel 100 so that a plurality of sandwich panels 100 are continuously assembled ( 103 is formed, and through-holes 105 are formed to insert a plurality of rivets 104.

아울러 샌드위치 패널(100)의 타측 단부에 접합부(103)와 대응되어 이에 삽입되도록 아연도금강판(101)을 접합부(103)의 길이만큼 절곡하여 돌출접합부(106)를 형성하고, 이에 통공(105)과 동일한 위치에 대응되는 통공(107)을 형성한다.In addition, the galvanized steel sheet 101 is bent by the length of the junction portion 103 to correspond to the junction portion 103 at the other end of the sandwich panel 100 so as to be inserted therein, thereby forming a protruding junction portion 106, thereby through-hole 105. To form a through hole 107 corresponding to the same position.
