By the way, in the soundproof room 11, from the viewpoint of disaster prevention, nonflammable materials are used for the sound absorbing material 12a on the inner wall surface and the tile material 12c spread on the floor. When a new space is constructed, additional disaster prevention equipment may be required depending on the degree of sealing. Under these circumstances, an automatic fire extinguishing device 24 is provided on the ceiling 12b of the soundproof room 11 in order to detect an abnormality at an early stage in the event of a fire in the room and to minimize damage.

The automatic fire extinguishing system 24 is a downward discharge type fire extinguishing system (sprinkler), and as shown in FIG. It is integrally equipped with a discharge nozzle 26 capable of discharging a fire extinguishing agent into the room upon sensing by a built-in heat sensing section (not shown). Further, on both sides of the discharge nozzle 26, a pressure filling port 27 is attached to one side, and a pressure gauge 28 is attached to the other side. A low melting point metal is used for the heat sensing part, and when the heat collecting plate 26a at the lower end of the discharge nozzle 26 detects heat from the fire source, the low melting point metal melts and the pressurized gas in the container is sealed. The plug and the heat collecting plate 26a are blown away, and the extinguishing agent begins to be released.

Here, the installation position of the automatic fire extinguishing device 24 is set in consideration of the arrangement of the lighting 19, the speaker 21, the fan 22, various cover members 29, etc. so as not to lose the functionality of the soundproof room 11. (Figure 3). In particular, the position of the discharge nozzle 26, that is, the position of the heat detection unit, and the position of the fan 22 are in a side-by-side relationship with each other so as to promote the rise of heat from the fire source in the upward airflow formed by the operation of the fan 22. It is set up to be. Further, as shown in FIGS. 4 and 6, by arranging the discharge nozzle 26 at the height of the ceiling 12b, that is, in correspondence with the opening 12d of the ceiling 12b, the fire extinguishing agent container 25 is placed outside the ceiling 12b. It is set in. The extinguishing agent container 25 is covered by a box-shaped extinguishing device cover 30, and the extinguishing agent container 25 is removably attached to a mounting portion 31 provided on the upper plate 30a of the extinguishing device cover 30.

On the other hand, the width dimension is similarly formed to be as small as possible so as to correspond to the outer diameter dimension of the fire extinguishant container 25.

In this way, since the soundproof room 11 is provided with the integrated automatic fire extinguishing system 24 including the fire extinguishing agent container 25 on the ceiling 12b, an initial fire can be extinguished quickly without relying on human operations. Furthermore, the fan 22 installed on the ceiling 12b at the same height as the automatic fire extinguishing system 24 forms an upward air current inside the soundproof room 11 when it operates, so that the heat from the fire source is promoted to rise quickly and quickly. Reliable heat detection becomes possible.

In addition, since the soundproof room 11 can be transported with the automatic fire extinguishing device 24 still installed on the ceiling 12b, the soundproof room 11 can be put into use immediately without any work required to install it. In other words, it is possible to obtain a structure of the soundproof room 11 that is easy to install and can exhibit an excellent disaster prevention function in the event of an emergency, thereby promoting the safe use of the soundproof room 11 in the various environments in which it is installed. It becomes something you get.

Furthermore, by arranging the discharge nozzle 26 of the automatic fire extinguishing system 24 in accordance with the height position of the ceiling 12b, the fire extinguishing agent container 25 is provided outside the ceiling 12b, thereby improving the space utilization efficiency in the soundproof room 11. can be increased. Moreover, in combination with the integrated structure of the automatic fire extinguishing system 24, the fire extinguishing system cover 30 can be made small, so the external beauty of the soundproof room 11 is not impaired, and the thickness is increased over the entire ceiling 12b. This inconvenience will be eliminated.

In addition, since the fire extinguishing device cover 30 is provided with the mounting portion 31 to which the fire extinguishing agent container 25 can be attached and detached, the automatic fire extinguishing device 24 can be stably held at the ceiling 12b position. Furthermore, since the mounting portions 31 are a pair of fixing metal fittings having mating surfaces that abut in the vertical direction, they can be easily attached and detached even if the mounting space is limited.

Further, since the fire extinguishing device cover 30 is provided at a position retracted inward from the position of the outer wall surface of the casing 12, there is no risk of it coming into contact with other structures when installing the soundproof room 11. In particular, even in situations where the soundproof room 11 must be tilted to pass through, such as in a place with a narrow frontage in a building, the fire extinguishing device cover 30 can be kept low and transported safely and quickly.

Furthermore, as described above, the reliability of the automatic fire extinguishing system 24 can be improved by the fan 22 installed on the ceiling 12b of the soundproof room 11, but in addition to this, the smoke discharged from the fan 22 This allows outsiders to recognize the occurrence of a fire inside the 11, making it possible to respond quickly and accurately, which is required as an initial response in an emergency.
