Description

The present invention is mainly installed on the wall surface of a building such as a hotel, department store, office building, commercial building, condominium, hospital, school, theater, inn, factory, warehouse, station, etc., and is used for fire extinguishing activities inside. Involved in the improvement of the fire hydrant storage box that stores fire hydrants, nozzles, fire hydrant valves, fire hydrants, etc. The door can be attached, and the fire hydrant door can be easily and easily set on the storage box body to improve workability. Moreover, the storage box body is displaced back and forth with respect to the wall surface due to an error during construction. Regarding a fire hydrant storage box that allows the fire hydrant door to be securely and satisfactorily attached to the storage box body even when installed, and further allows a vertically openable door plate to be easily attached to the door frame of the fire hydrant door. It is a thing.

Generally, a fire hydrant storage box containing fire hoses, nozzles, fire hydrant valves, fire extinguishers, etc. used for fire extinguishing activities in the event of a fire is installed on the wall surface of a building such as a hotel, department store, or office building. ..

Conventionally, this type of fire hydrant storage box is installed in a state of being buried in a wall surface in a building, and is attached to a storage box body having an open front and a fire hydrant door which is attached to the storage box body to open and close the front opening of the storage box body. And (see, for example, Patent Document 1 and Patent Document 2).

FIG. 28 shows an example of the conventional fire hydrant storage box 30, and the front surface of the fire hydrant storage box 30 in which a fire hose, a nozzle, a fire hydrant valve, a hose storage device (all not shown) and the like are stored is opened in the internal space. The storage box main body 31 is provided with a fire hydrant door 34 composed of a door frame 32 attached to the inner peripheral edge of the storage box main body 31 on the opening side and a door plate 33 provided on the door frame 32 so as to be openable and closable. ..

In FIG. 28, 35 is a concrete wall, 36 is a wall finishing material, 37 is a rotating shaft of a fire hydrant door 34, 38 is a handle provided on a door plate 33, and 39 is a fastener composed of screws 39a and nuts 39b. ..

By the way, in the conventional construction of the fire extinguisher storage box 30 on a building, the storage box main body 31 is installed on the wall of the building according to the construction process of the building, and then the fire extinguishing door 34 is attached to the storage box main body 31 after the wall surface is completed. It is fixed by a fastener 39 composed of a screw 39a and a nut 39b, and the work of attaching the fire extinguishing door 34 to the storage box main body 31 is performed by two workers.

That is, in the work of attaching the fire extinguishing door 34 to the storage box main body 31, one of the two workers has the fire extinguishing door 34, and the fire extinguishing door 34 is installed in the wall surface of the building in a stored state. An angle-shaped connecting portion 32a that is fitted into the opening-side inner peripheral edge of the box body 31 and provided on the inner peripheral edge of the door frame 32 and an angle-shaped door mounting portion 31a provided on the opening-side inner peripheral edge of the storage box body 31. After aligning the positions of the screw holes formed at predetermined intervals in the connecting portion 32a and the door mounting portion 31a, the other worker puts the screws 39a in the screw holes of the connecting portion 32a and the door mounting portion 31a, respectively. The fire extinguishing door 34 was attached to the storage box main body 31 by inserting and tightening the nut 39b to each screw 39a.

Further, when the fire hydrant door 34 is fitted into the inner peripheral edge of the storage box main body 31 on the opening side and then the fire hydrant door 34 and the storage box main body 31 are screwed together, the door plate 33 can be easily screwed. However, at this time, the weight of the door plate 33 causes the fire hydrant door 34 to tilt forward as shown in FIG. 29, so that one worker must keep pressing the fire hydrant door 34 toward the storage box main body 31 side. I had to.

As described above, in the conventional fire hydrant storage box 30, when the fire hydrant door 34 is attached to the storage box main body 31, two workers, a worker holding the fire hydrant door 34 and a worker performing screwing work, are used. The fire hydrant door 34 cannot be attached by one worker, and the worker can prevent the fire hydrant door 34 from being displaced with respect to the storage box main body 31 or tilt the fire hydrant door 34 forward due to its own weight. There is a problem that the fire hydrant door 34 must be held until the fire hydrant door 34 can be fixed, which makes it difficult to construct the fire hydrant door 34.

On the other hand, a fire hydrant storage box that solves the above-mentioned problems has been developed and published as Japanese Patent Application Laid-Open No. 2010-104625 (see Patent Document 3).

That is, as shown in FIGS. 30A and 30B, the fire extinguishing plug storage box 30 is for plate-shaped support for supporting the door frame 32 of the fire extinguishing plug door 34 on the door mounting portions 31a at the left and right positions of the storage box main body 31. The hook 40 is inserted, the tip of the support hook 40 is inserted into the hook insertion slit 32b formed in the connecting portion 32a of the door frame 32, and the support hook 40 supports the door frame 32 of the fire extinguisher door 34. It is something that I tried to do.

Therefore, since the fire hydrant storage box 30 has a structure in which the fire hydrant door 34 can be supported by the support hook 40, an operator holding the fire hydrant door 34 becomes unnecessary, and one operator can perform screwing work. Has the advantage of being able to do.

However, in the fire hydrant storage box 30 shown in FIGS. 30A and 30B, when the fire hydrant door 34 is attached to the storage box main body 31, the tip of the plate-shaped support hook 40 is connected to the connecting portion 32a of the door frame 32. It must be inserted into the vertically long hook insertion slit 32b formed in the above, but since the hook insertion slit 32b cannot be seen from the operator side, it is difficult to insert the support hook 40 into the hook insertion slit 32b, and the fire hydrant door 34. There was a problem that it took time to set the hook in the storage box main body 31.

When the width of the hook insertion slit 32b is widened, the support hook 40 can be easily inserted, but when the fire hydrant door 34 is installed so as to be displaced in the left-right direction with respect to the storage box main body 30. Will cause another problem that the tip of the support hook 40 interferes with the rotation trajectory of the door plate 33 and the fire hydrant door 34 cannot be opened or closed.

Further, in the fire hydrant storage box 30, when the fire hydrant door 34 is supported by the support hook 40, the tip of the support hook 40 is located inside the door frame 32, so that the support hook 40 is in the front-rear direction. The length cannot be made too long. This is because if the support hook 40 is lengthened, it will interfere with the tip of the support hook 40 when the door plate 33 rotates.

As a result, when the storage box main body 31 moves back and forth with respect to the wall surface W due to an error during construction, the following problems occur.
For example, when the opening end of the storage box body 31 is deeper than the wall surface W, the door frame 32 does not get caught in the tip of the support hook 40 as shown in FIG. 31 (A), and the fire hydrant door 34 Can not be set in the storage box main body 31.
On the contrary, when the opening end of the storage box main body 31 protrudes in front of the wall surface W, the fire hydrant door 34 can be supported by the support hook 40 as shown in FIG. 31 (B), but the fire hydrant is stored. Depending on the processing tolerance of the box 30, when the door plate 33 rotates, it may interfere with the tip of the support hook 40, which causes a problem that the storage box main body 31 must be removed.

Further, the fire extinguishing plug storage box 30 is provided with a door plate (not shown) that can be vertically opened in the door frame 32, and the door plate has a rotation axis (not shown) in a lateral orientation on the left side and the right side of the door frame 32. Although it is supported so as to be vertically openable through the door frame 32, since the rotation shaft holes (not shown) formed on the left side and the right side of the door frame 32 are both formed in a circular shape, the rotation shaft is smoothly and smoothly formed in the rotation shaft hole. There is a problem that it is difficult to insert the door plate into the door frame 32, it takes time to align the rotation shaft hole and the rotation shaft, and the vertically opening door plate cannot be easily attached to the door frame 32.

As described above, even in the fire hydrant storage box 30 shown in FIGS. 30A and 30B, it is difficult to set the fire hydrant door 34 in the storage box main body 31, and there is an error in the front-rear direction when the storage box main body 31 is installed. If this occurs, there is a problem that the fire hydrant door 34 cannot be set in the storage box main body 31 or that the door plate 33 interferes with the support hook 40 when the door plate 33 rotates.
