によりシール漏れを生ずることがある。2. Description of the Related Art In a sprinkler fire extinguishing facility, since a water distribution pipe and a sprinkler head are separated from each other, they are connected to each other via a connection pipe called an unwinding pipe. This unwind tube connects the corners via a rotary joint, so
It is easy to adjust the horizontal or vertical position of the unwinding tube. However, since the unwinding pipe is placed in a horizontal state or a vertical state, the piping work is troublesome, and its length is longer than the straight line connecting the water distribution pipe and the sprinkler head. It is uneconomical.
Further, since the rubber packing is used for the sealing, the seal may leak due to deterioration or the like.

レキシブル管を用いるのは問題がある。The conventional flexible tube is convenient because it can be bent freely. However, the flexible pipe deforms when it is filled with high-pressure fire extinguishing water, distorting the ceiling on which the sprinkler head is mounted. Therefore, it is problematic to use this flexible tube for a high pressure unwinding tube.

As shown in FIG. 4, a spherical connecting portion 2A is formed on the outer periphery of the tip of the horizontal unwinding pipe 1, and an annular seal projection 21 is formed on the outer peripheral surface thereof.
To form. This connecting portion 2A is brought into contact with a hemispherical receiving port 23 provided in the receiving side connecting portion 2B of the branch pipe 26. The central axis 26C of the branch pipe 26 intersects with the central axis 1C of the unwinding pipe 1 at an angle γ. Presser part 20 to receiving side connecting part 2B
Then, the seal projection 21 is pressed against the inner surface 20a of the pressing portion 20. Then, the unwinding pipe 1 and the branch pipe 26 are fixed while being sealed as shown by the chain line. By thus tilting the central axis 26 of the branch pipe 26, the turning range θ of the unwinding pipe 1 can be fully utilized. The angle of inclination is preferably 1 / 2θ.
