Zusammenfassung:A linear joint for an exterior panel with an interfloor fireproof function according to the present invention is a linear joint which is arranged between floor slabs spaced apart from an exterior panel and constituting the exterior panel to improve fire resistance function of the exterior panel, and may comprise: a fire resistance structure filling material which is located between the exterior panel and the floor slab to prevent fire from spreading through the gap at the floor slabs; and an exterior panel finishing material which is located between the exterior panel and the fire resistance filling material to prevent the exterior panel from being deformed by flames. Therefore, according to the present invention, in order to prevent a fire at the wall body with respect to a fire rising through the gap formed at the surface after the steel plate of the inside skin of the exterior panel constructed at the outer wall of a warehouse building is creased by flames, a fireproof plasterboard, a CRC board, Cerakwool and the like are used as the finishing material of an exterior panel. Consequently, although the steel plate of the inside skin at the lower side is creased, the upper side of the exterior panel finishing material maintains the contact strength with the exterior panel, such that construction costs may be reduced, and the optimal thickness may be achieved, thereby satisfying a reinforced regulation according to which a fire should be prevented from spreading from the lower floor to the upper floor for two hours (the fire resistance function). 개시된 본 발명에 따른 층간 방화기능을 구비한 외장판넬용 선형조인트는, 외장판넬을 구성하는 외장판넬과 이격되는 바닥 슬라브의 사이에 배치되어 상기 외장판넬의 내화성능을 향상시키는 선형조인트로서, 상기 외장판넬과 상기 바닥 슬라브 사이에 위치되어, 상기 바닥 슬라브의 틈새로 화재가 확산되는 것을 방지하는 내화구조 채움재; 및 상기 외장판넬과 상기 내화구조 채움재의 사이에 위치되어, 화염으로부터 상기 외장판넬의 변형을 방지하도록 구비된 외장판넬 마감재;를 포함한다. 본 발명에 의하면, 물류창고 건물 외벽에 구성된 외장판넬의 내피재 강판이 화염에 의해 울어 표면에 형성된 틈을 통해 뚫고 올라가는 화재에 대한 벽체 쪽 화재 방화를 위해 외장판넬 마감재로 방화석고보드, CRC보드, 세라크 울 등을 이용하므로 아래쪽 내피재 강판은 울지만 외장판넬 마감재의 상측은 외장판넬과 밀착강도를 유지하게 하면서 공사비 절감과 함께 최적의 두께를 통해 아래층에서 위층으로 화재가 2시간(내화성능)동안 발생하지 않게 하는 강화된 법규를 충족시키는 효과가 있다.
