Description

The present invention relates to a booth used for office work, meetings, and the like.

2. Description of the Related Art Conventionally, there has been known a booth capable of suppressing the intrusion of external noise and human voices and increasing the degree of concentration in an internal space. In the booth industry of this kind, movable booths have been introduced according to the notification titled "About sending work materials related to firefighting equipment, etc." issued by the Fire and Disaster Management Agency on November 2, 2018 By installing a downward discharge type automatic fire extinguishing device for residential use (see, for example, Non-Patent Document 1), the special measure that the installation of sprinkler heads, etc., which was conventionally required, can be exempted.

Therefore, in recent booths of this type, it has become common practice to provide a downward discharge type automatic fire extinguishing device on the ceiling (see, for example, Non-Patent Document 2).

In the attached state, the cover is attached to the outer surface of the ceiling of the booth together with the fire extinguishing agent storage container and the fire extinguishing agent injection nozzle. That is, in the conventional one, it is necessary to attach the fire extinguishing device to the upper surface of the ceiling panel from the outside space side.

By the way, recently, there are many cases where this type of booth is regarded as a "living room" under the Building Standards Law, and it is rare that the height dimension of the internal space is required to be 2100 mm or more by the provisions of the law. Absent. On the other hand, this type of booth is sometimes installed in an office space with a ceiling height of, for example, about 2300 mm, and there are cases where only a narrow space is left between the ceiling of the booth and the architectural ceiling of the external space. . Cramped work is required to attach the fire extinguishing device to the ceiling of the booth from above under such an environment.

Such a problem may also occur when the fire extinguishing device is mounted on the ceiling plate of the booth in an exposed state without having a cover, and some countermeasures are desired.

With such a configuration, the extinguishing agent storage container 81 and the container holder 53 that holds the extinguishing agent storage container 81 can be attached to the ceiling plate 51 from the interior space IS side. Therefore, even if the building ceiling of the external space OS is relatively low and only a narrow space is left between the ceiling 5 of the booth B, the fire extinguishing device 8 having the relatively bulky fire extinguishing agent storage container 81 can be installed in the booth B. It becomes possible to easily attach it to the ceiling 5. - 特許庁In other words, according to this configuration, even if the ceiling 5 of the booth B is set high and the internal space IS has a margin, the fire extinguisher is installed under a relatively low building ceiling without causing difficulty in installing the fire extinguisher. This makes it possible to reasonably improve the degree of freedom of arrangement while complying with the aforementioned Building Standards Act and the like.

Moreover, in this embodiment, since the cover 50 covering substantially the entire extinguishing agent storage container 81 is provided, the extinguishing device 8 can be prevented from being exposed to the external space OS.

Moreover, in this embodiment, the cover 50 can be attached to the ceiling plate 51 not only from the inner space IS side but also from the outer space OS side, so that the cover 50 can be attached to the ceiling panel 51 from the outer space OS side. An assembly procedure can be selected. 16 to 21 show sub-mounting modes for mounting the cover 50 to the ceiling plate 51 from the outside space OS side. In the sub-mounting mode, first, after the container holder 53 and the fire extinguishing agent storage container 81 are attached to the ceiling plate 51 by the procedure according to the main mounting mode, the cover 50 is attached from the outside space OS side. At this time, the cover 50 assumes a posture horizontally turned by 90 degrees with respect to the posture in the main mounting mode. Then, the cover 50 is placed on the ceiling plate 51 in such a horizontal swirling posture and screwed. As shown in FIG. 18, the bolt v2 used at this time is screwed into an upward nut 511 fixed to the ceiling plate 51 through bolt insertion holes 508a and 508b formed in the flange 507. Since these upward nuts 511 are attached by rotating the cover 50 horizontally by 90 degrees, they can be arranged at positions that do not interfere with the container holder 53 . This sub-mounting mode is adopted when there is a relatively large external space OS above the ceiling plate 51. Therefore, as shown in FIG.
