Description

  The present invention is mainly installed on a wall surface in a building such as a hotel, department store, office building, commercial building, condominium, hospital, school, theater, inn, factory, warehouse, station, etc., and used for fire fighting activities inside. In connection with the improvement of fire hydrant storage boxes for storing fire hoses, nozzles, fire hydrant valves, fire extinguishers, etc., especially when installing fire hydrant doors on the main body of the storage box that is embedded in the wall of a building, In addition to being able to install the door, the fire hydrant door can be easily and easily set on the main body of the storage box to improve workability. A fire hydrant storage box that can securely and satisfactorily attach a fire hydrant door to the main body of the storage box, and that can be easily attached to the door frame of the fire hydrant door. about It is intended.

  Generally, fire hydrant storage boxes containing fire hoses and nozzles, fire hydrant valves, fire extinguishers, etc., used for fire fighting activities in the event of a fire are installed on the walls of buildings such as hotels, department stores, and office buildings. .

  Conventionally, this kind of fire hydrant storage box is installed in the state of being buried in the wall surface of the building, and the front of the storage box main body is opened and the fire hydrant door is attached to the storage box main body and opens and closes the front opening of the storage box main body. (See, for example, Patent Document 1 and Patent Document 2).

  FIG. 28 shows an example of a conventional fire hydrant storage box 30, and the fire hydrant storage box 30 has an open front surface in which a fire hose, a nozzle, a fire hydrant valve, a hose storage device (all not shown) and the like are stored. And a fire hydrant door 34 comprising a door frame 32 attached to the inner peripheral edge on the opening side of the storage box main body 31 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 the fire hydrant door 34, 38 is a handle provided on the door plate 33, 39 is a fastening tool comprising a screw 39a and a nut 39b. .

  By the way, in the construction of the conventional fire hydrant storage box 30 in the building, the storage box body 31 is installed on the wall of the building in accordance with the building construction process, and then the fire hydrant door 34 is attached to the storage box body 31 after the wall surface is completed. It was fixed with a fastening tool 39 comprising a screw 39a and a nut 39b, and the installation work of the fire hydrant door 34 to the storage box body 31 was performed by two workers.

  That is, the operation of attaching the fire hydrant door 34 to the storage box main body 31 is a storage operation in which one of the two workers has the fire hydrant door 34 and the fire hydrant door 34 is embedded in the wall surface of the building. An angle-shaped connecting portion 32a provided at the inner peripheral edge of the door frame 32 and an angle-shaped door mounting portion 31a provided at the inner peripheral edge of the storage box main body 31. After the positions of the screw holes formed at predetermined intervals in the connecting portion 32a and the door mounting portion 31a are aligned, the other worker puts screws 39a in the screw holes of the connecting portion 32a and the door mounting portion 31a, respectively. The fire hydrant door 34 was attached to the storage box body 31 by inserting and tightening the nut 39b to each screw 39a.

  In addition, after the fire hydrant door 34 is fitted into the inner peripheral edge of the opening side of the storage box body 31, the door plate 33 can be easily screwed when the fire hydrant door 34 and the storage box body 31 are screwed. At this time, the fire hydrant door 34 tilts forward as shown in FIG. 29 due to the weight of the door plate 33, so one worker must keep pressing the fire hydrant door 34 toward the storage box body 31. I had to.

  As described above, in the conventional fire hydrant storage box 30, when attaching the fire hydrant door 34 to the storage box body 31, two workers, an operator holding the fire hydrant door 34 and an operator holding the screw, One worker cannot install the fire hydrant door 34, and the worker prevents the fire hydrant door 34 from being displaced relative to the storage box body 31, or the fire hydrant door 34 tilts forward due to its own weight. There is a problem that it is necessary to keep the fire hydrant door 34 until the fire hydrant door 34 can be fixed, and the construction cannot be easily performed.

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

  That is, the fire hydrant storage box 30 is a plate-shaped support for supporting the door frame 32 of the fire hydrant door 34 on the door mounting portions 31a at the left and right positions of the storage box body 31, as shown in FIGS. 30 (A) and 30 (B). 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 door frame 32 of the fire hydrant door 34 is supported by the support hook 40. It is what you do.

  Therefore, since the fire hydrant storage box 30 has a structure that can support the fire hydrant door 34 with the support hook 40, an operator holding the fire hydrant door 34 is not required, and a single worker can fix the screw. There is an advantage that can be done.

  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 distal end portion of the plate-like support hook 40 is connected to the connecting portion 32 a of the door frame 32. However, 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. There is a problem that it takes time to set the storage box body 31 to the storage box body 31.

  If the width of the hook insertion slit 32b is increased, the support hook 40 can be easily inserted. However, when the fire hydrant door 34 is installed in a state shifted in the left-right direction with respect to the storage box body 30. This causes another problem that the front end of the support hook 40 interferes with the rotation orbit of the door plate 33 and the fire hydrant door 34 cannot be opened and closed.

  Further, when the fire hydrant storage box 30 supports the fire hydrant door 34 with the support hook 40, the front end portion of the support hook 40 is located inside the door frame 32, so The length cannot be made too long. This is because if the supporting hook 40 is lengthened, it interferes with the tip of the supporting hook 40 when the door plate 33 rotates.

As a result, when the storage box body 31 moves back and forth with respect to the wall surface W due to an error during construction, the following problem occurs.
For example, when the opening-side tip of the storage box main body 31 enters behind the wall surface W, the door frame 32 is not caught by the tip of the support hook 40 as shown in FIG. Will not be able to be set in the storage box body 31.
On the contrary, when the opening end of the storage box body 31 comes out ahead of the wall surface W, the fire hydrant door 34 can be supported by the support hook 40 as shown in FIG. 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 body 31 must be removed.

  Further, the fire hydrant storage box 30 includes a door plate (not shown) that can be opened vertically on the door frame 32, and the door plate has a rotation shaft (not shown) in a lateral orientation on the left and right sides of the door frame 32. The rotary shaft holes (not shown) formed on the left and right sides of the door frame 32 are both formed in a circular shape, so that the rotary shaft is smoothly and smoothly placed in the rotary shaft hole. There is a problem that it is difficult to insert into the door frame, and it takes time to align the rotation shaft hole and the rotation shaft, and it is difficult to attach the vertically-open door plate to the door frame 32.

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