  For example, in the embodiment of FIG. 16, since the connection of the external water supply pipe is made from the right side of the tunnel hydrant device 10, the valve storage frame 106 is arranged on the right side. If there is a place where a water supply pipe is connected from the left side of the fire hydrant device 10, the valve storage frame 106 is moved to the left side, and at the same time, the fire extinguisher storage frame 102 is moved to the right side. The tunnel fire hydrant device 10 according to the present invention can be easily applied to the place where the connection is made from the left side.

  Further, in the embodiment of FIG. 16, the fire extinguisher storage frame 102, the hose storage frame 104 and the valve storage frame 106 are configured. However, depending on the location, the fire extinguisher storage frame 102 is not used, and the hose storage frame is used. It is also possible to easily assemble a tunnel fire hydrant device composed of two frames 104 and a valve housing frame 106.

  Of course, the fire extinguisher storage frame 102 can be used alone, but this is used as a simple fire extinguisher storage device rather than a tunnel fire hydrant device, but as a modified use of the embodiment according to the present invention. Is possible.

  Note that a closing plate may be detachably attached between the frames such as the fire extinguisher storage frame 102 and the hose storage frame 104.

In the above embodiment, the upper decorative frame is separately assembled as a front decorative frame having a split structure on the upper part of the front decorative frame 26 attached to the frame body 12. Needless to say, the decorative frame 26 may be integrated with the decorative frame 26. Further, in the above embodiment, the upper closing plate portion 66 is integrally extended behind the upper decorative frame 62, but it goes without saying that an independent closing plate may be used.
