Summary:Disclosed is a pipe connecting device that can firmly connect an expansion pipe to which a sprinkler head is coupled, and a branch pipe through which fire prevention water flows in. The pipe connecting device, which is a pipe connecting device for connecting an expansion pipe coupled to a sprinkler head and a branch pipe through which fire prevention water flows in, comprises: a housing having a first slit, which can have the expansion pipe inserted into the front thereof and the branch pipe inserted into the rear, extends in one direction, has the inside penetrated, and is recessed in one direction on the inner circumference surface thereof, and a second slit recessed in a direction of intersecting with the first slit; a sleeve ring inserted into the housing, having the shape of a ring having the thickness thereof increasing from the front to the rear with respect to one direction, and coupled to the outer circumference surface of the expansion pipe; a pressurizing ring having the center penetrated in one direction, including coupling protrusions, which can be inserted into the first slit and the second slit, on an outer circumference surface, inserted into the rear of the housing and pressurizing the sleeve ring forward; and a fixing unit inserted into the rear of the housing, fixing the position of the pressurizing ring and coupling the branch pipe and the pressurizing ring. The first slit is provided in a plurality and is formed at intervals in a circumferential direction on the inner circumference surface of the housing. The coupling protrusions are provided in a plurality and are spaced apart along the circumference of the pressurizing ring to correspond to the positions of the plurality of first slits. 스프링클러 헤드가 체결되는 신축배관과 방화수가 유입되는 가지배관을 견고하게 결합시킬 수 있는 배관 연결장치를 개시한다. 배관 연결장치는 스프링클러 헤드에 결합된 신축배관과 방화수가 유입되는 가지배관을 연결하기 위한 배관 연결장치로서 전방에 신축배관이 삽입 가능하고 후방에 가지배관이 삽입 가능하며 일방향으로 연장되고 내부가 관통되고 그 내주면에 일방향으로 함몰된 제1 슬릿과 제1 슬릿에서 교차하는 방향으로 함몰된 제2 슬릿을 가지는 하우징, 하우징에 삽입되고 일방향을 기준으로 전방에서 후방으로 두께가 증가하는 링형상을 가지며 신축배관의 외주면에 결합되는 슬리브링, 일방향으로 그 중심이 관통되고 외주면에 제1 슬릿 및 제2 슬릿에 삽입 가능한 체결돌기를 구비하고 하우징의 후방에 삽입되며 슬리브링을 전방으로 가압하기 위한 가압링 및 하우징의 후방에 삽입되고 가압링의 위치를 고정시키며 가지배관과 가압링을 결합시키기 위한 고정유닛을 포함한다. 제1 슬릿은 복수개로 마련되고 하우징의 내주면에 원주방향을 따라 이격되어 형성된다. 체결돌기는 복수개로 마련되고 복수의 제1 슬릿의 위치에 대응하여 가압링의 둘레를 따라 이격된다.
