A branch pipe 18 is connected to the water supply pipe 16, and a water control valve 19, an electromagnetic valve type opening / closing control valve 20 which is normally closed, and a header 21 are sequentially connected to the branch pipe 18. .

A closed sprinkler head 14 and a fire detector 23 near each sprinkler head 14 are provided in each of the watering areas of the dwelling unit 8, such as the kitchen, the living room, the bedroom, and the bathroom. Will be placed. Each sprinkler head 14 is independently connected to the distal end side of the branch pipe 24 via a joint 25. Further, a few sprinkler heads 14 which are close to each other are connected to the branch pipe 24 by a joint 25 in series with each other.
The proximal ends of these branch pipes 24 are connected to the header 21 via a joint 26 such as a union. In addition,
When a plurality of sprinkler heads 14 are provided in the same room, the fire detector 23 is equipped with a plurality of sprinkler heads.
One head 14 may be provided. It is convenient to install the water control valve 19, the opening / closing control valve 20, and the header 21 in a device box that houses a switchboard or gas meter provided in the dwelling unit 8 or in a pipe shaft or the like. A control panel 27 is installed near the valve 19 and the like.

On the control panel 27, a control circuit 28, an alarm bell 29 as a fire alarm for notifying the opening operation of the opening / closing control valve 20, an alarm lamp 30, and the opened opening / closing control valve 20 are closed. There is provided a release switch 31 for doing so. Each fire detector 23 is connected to the control circuit 28 by the wiring 32.
The open / close control valve 20 is connected to the control circuit 28 by the wiring 33. As all the fire detectors 23, ones that operate earlier than all the sprinkler heads 14 are used for each watering area or each of a plurality of watering areas, and the open / close control valve 20 in a normally closed state is fired. The control circuit 28 is configured to be opened by the sensing operation of the sensor 23.

In the living room of the dwelling unit 8 and the like, a house information board 35 having an interphone 34 used for communication with the outside of the entrance is provided. Therefore, the house information board 35 also has an alarm bell as an alarm device. 36 is provided and the control circuit 2 is provided by wiring 37.

The branch pipe 24 is preferably made of a flexible pipe and has good piping work, such as a polyethylene pipe and a polybutene pipe which are lightweight and have high strength and excellent temperature characteristics.

The joint 25 connecting the sprinkler head 14 to the branch pipe 24 is composed of an elbow 39 and a union 40 at the distal end side, and a T-shaped joint 41 and a union 40 at an intermediate position. As shown in the front view of the longitudinal section of the main part in FIG. 3, it is fixed to the ceiling beam 43 by a mounting tool 42. The illustrated mounting tool 42 is a ┏ type, and a vertical piece 45 is provided on the upright piece 44, and a horizontal piece 46 is fixed to the ceiling beam 43 using an insert 47, and an elbow 39 is mounted. By adjusting the mounting position of the standing piece 44 to the surface 48 in the vertical direction along the long hole 45 and tightening the mounting screw 49, the elbow 39 and the sprinkler head 14 are fixed to the ceiling beam 4.
The tip of the sprinkler head 14 is fixed to the water spray area (range) 52 from the cutout hole 51 of the ceiling plate 50 at a predetermined height. Reference numeral 53 is an elbow 39
Is a protective cap that is fitted or attached to the tip end of the sprinkler head 14 by screwing means to protect the sprinkler head 14 from construction work such as the ceiling plate 50.

After the interior work is completed, the protective cap 53 is removed from the elbow 39, and a cosmetic plate is attached instead. In the case of a house, the sprinkler-head 14 is preferably a high-sensitivity small-water type, and the fire detector 23 is
Although the constant temperature spot type is used, various types such as ionization type, photoelectric type, and differential type can be used.

Next, the operation of the above equipment will be described. In the normal state where the fire detector 23 does not operate, the opening / closing control valve 20 is closed, and the header-21, the branch pipe 24 and the sprinkler are closed.
The head 14 has no pressure water and is in the same state as a so-called dry sprinkler, or is in a non-pressurized state even if there is water in the branch pipe 24. In this state, when a fire occurs in a certain sprinkling area (range) and the fire detector 23 performs a sensing operation, the opening / closing control valve 20 opens through the control circuit 28, the boost pump 12 is activated, and the auxiliary water tank. The water of 11 is sent to the branch pipe 18 through the water supply pipe 16 at an appropriate pressure, and the water of the branch pipe 18 is filled into the respective branch pipes 24 and the sprinkler heads 14 through the header 21.

At the same time as the opening / closing control valve 20 is opened, the alarm lamp 30 of the control panel 27 is turned on and the alarm bell 29 is sounded.
The alarm bell 36 of the house information panel 35 in the dwelling unit 8 also sounds, and a central monitoring panel (not shown) is also notified by the wiring 38 as a warning state. As a result, the resident can immediately and intensively know the operation of the fire detector 23 in the dwelling unit 8, and can quickly respond to the fire occurrence. The opening operation of the opening / closing control valve 20 associated with the fire detection operation of the fire detector 23 is notified to the central monitoring panel by the notification means 38, which is convenient for security management of the dwelling unit 8. When the fire further spreads and reaches a high temperature, the fusible alloy of the sprinkler-head 14 in the sprinkling region melts and opens, and the water in the branch pipe 24 is discharged from the sprinkler-head 14 to extinguish the fire. At this time, the sprinkler head 14, the joint 25, and the like try to dance due to large fluctuations in water pressure, but the joint 25 and the branch pipe 24
Since the joint 25 side of the joint 25 is fixed to the building member 43 with the fixture 42, even if the joint 25 or the joint 25 side of the branch pipe 24 is subjected to a water pressure fluctuation that appears at the start of water discharge or the end of water discharge, for example. Does not vibrate, and damage such as leakage of the joint 25 portion due to vibration is prevented.

Then, the above-mentioned warning state is manually released, and
The water discharge of the sprinkler head 14 can be stopped easily by turning on the release switch 31 provided on the control panel 27. The opening / closing control valve 20 is closed by the closing operation of the release switch 31, and the alarm lamp 30
Is turned off and the alarm bells 29 and 36 are stopped, and the standby state is restored. Further, by closing the water control valve 19, inspection and maintenance of the sprinkler head 14 and the connecting portion of the branch pipe 24 can be easily performed. Even if the sprinkler-head 14 is opened in a non-warning state, even if the sprinkler-head 14 is opened, the opening / closing control valve 20 remains closed and water is not discharged. Therefore, the tip of the sprinkler-head 14 is accidentally impacted. Since it does not discharge water even when it is opened and released, it does not cause water damage accidents, and is suitable for fire extinguishing equipment for houses where ordinary people come in and go out.

The sprinkler heads 14 are connected to the header 21 by individual branch pipes 24, respectively.
Each branch pipe 24 has a simple pipe shape with a small number of bends without being restricted by the arrangement position of the other sprinkler heads 14. This reduces the number of joints, reduces the risk of water leaks, and reduces equipment costs. All branch pipes 2
4, the base side is connected at the position gathered by the header 21. Therefore, the piping work is simplified and the construction cost is reduced. The length of the branch pipe 24 for each sprinkler head 14 was shorter and the pressure loss was smaller than that of the conventional equipment that does not use a header. Furthermore, all branch pipes 24
Can be made to have the same diameter, and the effect of eliminating connection mistakes in piping can be expected.

In the case of the embodiment, since the flexible pipe is used as the branch pipe 24, the connection work using the joints in the middle portion of the branch pipe 24 is completely different from the conventional pipe using the hard pipe. It becomes unnecessary, and the piping work is almost completed by simply connecting the base side of the branch pipe 24 to the header 21 and the end side to the sprinkler head 14, and the piping work is extremely simple. As the number of sprinklers has decreased, it has become suitable as a sprinkler-extinguishing system for homes.

In the above embodiment, the case of the collective housing has been described, but it can be used for a single-family house or a building. In the case of a single-family house, the branch pipe 18 may be connected to a water pipe drawn from the water main via the main valve, for example, a sanitary pipe. In the case of a building, the header for each floor or block for each floor is
21 may be provided, and each header-21 and the sprinkler head 14 provided in each sprinkling area may be connected by a branch pipe 24.
