経済である。2. Description of the Related Art In sprinkler fire extinguishing equipment, a water pipe and a sprinkler head are separated from each other, so they are connected through a connecting pipe called an unwinding pipe. Since the corner portions of this unwinding pipe are connected via right-angled elbow joints, the pipe is installed from the water pipe to the sprinkler head in either a horizontal or vertical position. As a result, the unrolled pipe bends, making piping work troublesome, and the total length thereof is longer than the length of a straight line connecting the water pipe and the sprinkler head (the shortest connection length), which is uneconomical.

フレキしブル管を用いるのは問題である。Conventional flexible tubes are convenient because they can be bent freely. However, when the flexible pipes are filled with high-pressure fire extinguishing water, they become deformed, distorting the ceiling where the sprinkler heads are attached. Therefore, it is problematic to use this flexible tube as an unwinding tube that is subjected to high pressure.

はDESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings, in which the same reference numerals have the same names and functions. One end 1a of a straight cylindrical unwinding pipe 1 is connected to a water distribution pipe 3 via a ball-shaped universal joint 2, and the other end 1b is connected to a sprinkler head 5 via a ball-shaped universal joint 4. The ball-shaped universal joints 2 and 4 consist of a ball portion A and a socket portion B, and the socket portion B is formed at the tip of the branch pipe 6 and the fitting tube 7, respectively. As shown in FIG. 2, the socket part B includes a cap nut 11 that holds the ball part A, a receiving part 12 that supports the ball part A, and a ball part A and the receiving part 1.
2 and a packing 13 interposed between them. The unwinding tube 1 is provided with an expansion joint 10 for length adjustment. 16 is a cap nut screwed into the external thread 20 of the outer tube P2, 17 is a lock ring fitted to the inner tube P1, 18 is a washer, and 19 is a packing. Next, the operation of this embodiment will be explained. First, the branch pipe 6 is connected to the water distribution pipe 3, and the attachment pipe 7 is fixed to a fixing member 28 such as a C channel on the ceiling 27 using a U-shaped fitting 29 or the like. Next, after loosening the cap nut 16 of the expansion joint 10 to make the unwinding tube 1 expandable and retractable, the ball portion A of the one end 1a of the tube 1 is brought into contact with the socket portion B of the branch tube 6 via the packing 13. At the same time, rotate the cap nut 11 to tighten the ball part A. Next, the ball part A of the other end 1b of the pipe 1 is brought into contact with the socket part B of the attachment pipe 7 of the sprinkler head 5 protruding from the ceiling 27 via the packing 13, and the cap nut 11 is rotated to make the ball Tighten part A. Then, the straight cylindrical unwinding pipe 1 becomes straight and connects the branch pipe 6 and the attachment pipe 7 at the shortest distance. In this state, the cap nut 16 of the expansion joint 10 is rotated to fix the inner pipe P1 and the outer pipe P2, and the packing 19 is pressed via the lock ring 17 and washer 18.
Seal. Then, the sprinkler head 5 is attached to the tip of the attachment pipe 7. As mentioned above, the unwinding pipe 1 is arranged between the branch pipe 6 and the attachment pipe 7 in a straight state, but
How to determine the length L of the unwinding tube at this time will be explained with reference to FIG. 3. Connection part 3 between water pipe 3 and branch pipe 7
0 and the connection part 31 between the sprinkler head 5 and the attachment pipe 7 is defined as r, and the distance between this straight line R and the X axis is
-The angle on the Y plane is Ψ, the angle between this straight line R and the Z axis is θ, the length of the branch pipe 6 is L1, and the height of the attachment pipe 7 of the sprinkler head 5 is L2. Unwinding tube length L

を固定するようにしても良い。It can be obtained from [Formula 1]. Note that L11 is an error during construction, but this error is absorbed by the action of the expansion joint 10. Furthermore, since the length L1 of the branch pipe 6 and the height L2 of the attachment pipe 7 of the sprinkler head 5 are constant if common pipes are used, it is also possible to directly measure the length L schematically. Note that the mounting pipe 7 is attached to the unwinding pipe 1 in advance, and the length is adjusted using the expansion joint 10 so that the universal joint 4 is directly above the installation position of the sprinkler head 5, and then the cap nut 11 is tightened. Alternatively, the mounting pipe may be fixed by

Since the unwinding pipe can connect the water distribution pipe and the sprinkler head in a straight state, the length of the unwinding pipe can be shortened compared to the conventional example. In addition, since a ball-shaped universal joint is used, the direction of the unwound pipe can be changed freely, so the piping work is extremely simple and the working time is shortened compared to the conventional example. Further, unlike the conventional example, even if high-pressure fire extinguishing water passes through the unwinding pipe, the pipe does not deform, so reliability against pressure is improved.
