In the test jig unit 200 of the fire hydrant device and the test method of the fire hydrant device configured as described above, the support 201 is installed on the floor surface F, and a plurality of connecting bodies 211 are arranged in a row from the support 201 in the X1 direction. In connection with each other, the fire hydrant device 100 is installed in the recess 203 of the support 201. As a result, the upper surface 202 of the support 201 and the upper surface 212 of the connecting body 211 become higher than the floor surface F. Assuming that the floor surface F is, for example, the road surface 1T of the roadway 1 of the tunnel T in which the fire hydrant device 100 is installed, and the upper surface 202 of the support 201 and the upper surface 212 of the connecting body 211 are assumed to be the road surface 2T of the observer passage 2. A test was conducted in which the elevating unit 20 of the fire hydrant device 100 was raised, and the housed hose 24 was stretched in the X1 direction on the upper surface 202 of the support 201 and the upper surface 212 of the connecting body 211 assuming the road surface 2T of the observer passage 2. It can be carried out. Therefore, the test can be easily performed without performing a large-scale work such as digging down the floor surface F for installing the fire hydrant device 100.

Further, a test in which the floor surface F is assumed to be the road surface 1T of the roadway 1 and the hose 24 is stretched along the floor surface F assumed to be the road surface 1T of the roadway 1 is also performed without adding a test jig or installing work. It is very convenient because it can be done.

Further, since the connecting bodies 211 and 221 are connected in a row from the support body 201 in the X1 direction, the positional deviation between the support body 201 and the connecting bodies 211 and 221 is suppressed, and the test can be appropriately performed.

Further, the connection between the support 201 and the connecting body 211 and the connection between the plurality of connecting bodies 211 are fastened by bolts 205 and 215. Therefore, by fastening the bolts 205 and 215, a simulated observer passage can be assembled by the support 201 and the plurality of connecting bodies 211, and a test of extending the hose 24 from the fire hydrant device 100 in the X1 direction can be performed. Further, after the test is completed, the support 201 and the connecting body 211 can be disassembled and housed compactly by removing the bolts 205 and 215. Further, the bolt 205 connecting the support 201 and the connecting body 211 on the base end side in the X1 direction is removed, and the support 201 is rotated about the vertical axis again as shown by the two-dot chain line in FIG. By connecting the connecting body 211 to the X2 direction (see FIG. 8), it is possible to perform a test of extending the hose 24 by changing the drawing direction of the hose 24 with respect to the fire hydrant device 100.

Further, since the height of the support 201 and the height of the connecting body 211 are substantially the same, the support 201 and the connecting body 211 are connected to the upper surface 202 of the support 201 with the support 201 and the connecting body 211 installed on the floor surface F. The upper surface 212 of the body 211 is flush with each other. Therefore, it is possible to assume that the upper surface 202 of the support 201 and the upper surface 212 of the connecting body 211 are the road surface 2T of the observer passage 2, and perform the test assuming the road surface 2T of the observer passage 2 without a step.

It should be noted that the various shapes and combinations of the constituent members shown in the above-described embodiment are examples, and various changes can be made based on the design requirements and the like without departing from the gist of the present invention.

For example, various configurations of the support 201 and the connecting body 211 can be adopted, but the structure may be configured by assembling the outer shape with sheet metal or the like and then filling the inside with concrete. Further, height-adjustable adjusters (not shown) may be provided at the lower portions of the support 201 and the connecting body 211, or casters (not shown) that can roll in the horizontal direction may be provided. Further, a finishing material equivalent to the road surface 2T of the observer passage 2 may be formed in a panel shape and detachably attached to the upper part of the support 201 and the upper part of the connecting body 211.

Further, in the embodiment shown above, the elevating unit 20 is configured to be able to move up and down, but the present invention is not limited to this, and the configuration is installed on the roadway 1 side of the observer passage 2 (embedded in the observer passage 2).
