井裏に設置できないことがある。In the prior art described above, the joint provided at one end of the flexible tube is screwed to the connection port of the header, so that a space between the connection ports is used as a working space. , And there is a problem that the header becomes large. Also, 1
Since there is a limit to the number of connection ports provided in each header, in order to connect a large number of flexible tubes, a plurality of headers must be vertically connected. However, since the space between the slab and the ceiling plate of the building is narrow, it may not be possible to connect a plurality of headers in the vertical direction, and thus the number of flexible tubes to be connected is limited. In addition, there is a problem that the number of nipple connections must be significantly increased in order to connect a large number of headers.
Further, when the nipple and the header are long in the vertical direction, the nipple and the header may not be installed above the ceiling.

大きな負荷がかかり好ましくないという問題がある。Further, since a flexible tube is used to be somewhat longer, when the flexible tube is connected to a connection port provided at a lower portion of the header, a height distance between the connection port and the sprinkler head is reduced. In some cases, the flexible tube may be crawled on the ceiling material to be piped, so that there is a problem that a large load is applied to the ceiling material when the flexible tube is filled with water.

However, in the case of the screw-in method, not only is the connection work troublesome, but also if the tightening is weak, there is a risk of water leakage, and if it is too strong, the members may be deformed. there were. Further, in the case of the screw-in system, it is necessary to increase the interval between the connection ports provided in the header due to the work space, and there is a problem that the header itself becomes large. Furthermore, the connection work is troublesome and requires a lot of man-hours due to the narrow space above the ceiling.

ル部材２４を保持する。Next, the operation of joining the joint 16 to the connection port 10 configured as described above will be described. First, joint 1
6 is gripped by hand and its opening is fitted into the main body 12 of the connection port 10 and then pushed. As a result, the main body portion 17 and the engagement claw 20 of the joint 16 are slightly elastically deformed and move forward, and one of the ends comes into contact with the other party and stops moving forward. At this time, the projection 19 provided at the tip of the joint 16 is connected to the connection port 10.
The engaging claw 20 is located at the base side of each engaging portion 14 and holds the seal member 24 between the two.

ことができる。As described above, in this embodiment, the joint 16 attached to the flexible tube 15 can be connected to the connection port 10 of the header 5 with one touch without using tools or a special one-touch joint member. In addition, since the seal member 24 is interposed between the two, there is no risk of water leakage. In addition, since the convex portion 19 provided at the distal end of the joint 16 is fitted and held in the concave groove 13 provided in the flange portion 11 of the connection port 10, expansion due to an increase in internal pressure, that is, internal pressure increases. The detachment of the connecting part 10 and the main body part 17 can be suppressed. Furthermore, since the connection port 10 of the header 5 is provided in the left-right direction (horizontal direction), connection work of the joint is easy, and the number of connection steps can be significantly reduced. Further, since the joint 10 can be easily connected even when the interval between the connection ports 10 provided in the header 5 is reduced, the header 5 can be downsized.

が好ましい。By the way, the flexible tube 15 having a length of about 50 m is used by cutting it to a predetermined length at a site of a sprinkler facility. At this time, the connection port 10 of the header 5 and the distal end of the flexible tube 15 can be connected by heat welding. However, since the header 5 is installed at a high position on the ceiling, considering workability, It is preferable to make a one-touch connection using the joint 16 as described in the present embodiment.

If the marking 19a is provided by coloring or the like, when the header 19 is connected to the connection port 10 of the header 5, it is possible to check the clearance between the two and check the insertion failure. Further, the thickness of the body portion 12 of the connection port 10 is reduced, and the seal member 24 is connected to the joint 1 by utilizing the expansion of the body portion 12 caused by water pressure.
6 may be pressed against the inner surface of the main body 17 to maintain the sealing property.

ことは云うまでもない。In the above description, the case where a plurality of locking portions 14 are provided on the outer periphery of the main body 12 of the connection port 10 of the header 5 and the sealing member 24 is attached to each locking portion 14 has been described. The number of the portions 14 may be one or more, and the number of the seal members 24 may be one or more. Further, the connection port 10 is constituted by a flange portion 11 having a concave groove 13 and a main body portion 12 having a locking portion 14, and a joint 16 has a convex portion 19 at a distal end portion and a locking claw 2 on an inner wall.
0, the connecting portion 10 is constituted by the projecting portion 19 and the main body portion 17 having the locking claw 20 on the inner wall, and the joint 16 is formed by a concave groove. Alternatively, the main body 10 may have a flange portion 11 having a locking portion 13 and a locking portion 14 on the outer periphery. Needless to say, the connection structure of the present embodiment can be applied to the sprinkler fire extinguishing equipment of the first embodiment.
