Details will be described below.

（屋内駐車場）
屋内駐車場とは例えばビルやマンションなどの建物内に設けられた駐車場をいう。屋内駐車場は例えば複数の駐車区画（例：白い線で床面に引かれた囲み、機械式屋内駐車場における各段）を有しており、各駐車区画には例えば１台の自動車（例：普通自動車、軽自動車、自動二輪車）を駐車することができる。なお、自動車は、ガソリン自動車であってもよいし、燃料電池自動車などのような新しいタイプの自動車であってもよい。 (Indoor parking lot)
An indoor parking lot refers to a parking lot provided in a building such as a building or a condominium. An indoor parking lot has, for example, a plurality of parking sections (for example, an enclosure drawn on the floor with a white line, each stage in a mechanical indoor parking lot), and each parking section has, for example, one automobile (for example, : Normal car, light car, motorcycle) can be parked. The automobile may be a gasoline automobile or a new type of automobile such as a fuel cell automobile.

（加圧送水装置１０）
加圧送水装置１０は貯水層１００に貯水された水や消火栓から供給される水などを所定の圧力でもって第１配管３０に送水する装置である。所定の圧力は、特に限定されるものではないが、例えば、０．３５ＭＰａ以上１．４ＭＰａ以下の範囲内にあることが好ましい。加圧送水装置１０には例えばポンプや圧力タンクなどを用いることができる。貯水層１００は例えばビルの地下に設置される。 (Pressurized water supply device 10)
The pressurized water supply device 10 is a device that supplies water stored in the water reservoir 100 or water supplied from a fire hydrant to the first pipe 30 with a predetermined pressure. The predetermined pressure is not particularly limited, but is preferably in the range of 0.35 MPa to 1.4 MPa, for example. For example, a pump or a pressure tank can be used for the pressurized water supply apparatus 10. The water reservoir 100 is installed, for example, in the basement of a building.

（流水検知装置２０）
流水検知装置２０は第１配管３０中の流水を検知する装置である。第１配管３０中の流水を検知することによって、火災が生じているかどうかを判断することができる。流水検知装置２０には、例えば、自動警報弁型、作動弁型、またはパドル型のものを用いることができる。 (Running water detection device 20)
The flowing water detection device 20 is a device that detects flowing water in the first pipe 30. By detecting the flowing water in the first pipe 30, it can be determined whether or not a fire has occurred. As the flowing water detection device 20, for example, an automatic alarm valve type, an operation valve type, or a paddle type can be used.

（第１配管３０）
第１配管３０には例えば鋼管を用いることができる。第１配管３０は加圧送水装置１０に流水検知装置２０を介して接続される。第１配管３０と加圧送水装置１０との間には、流水検知装置２０が介在する限り、流水検知装置２０以外の他の装置がさらに介在していてもよい。 (First piping 30)
For example, a steel pipe can be used for the first pipe 30. The first pipe 30 is connected to the pressurized water supply device 10 via the flowing water detection device 20. As long as the flowing water detection device 20 is interposed between the first pipe 30 and the pressurized water supply device 10, another device other than the flowing water detection device 20 may further be interposed.

（感熱開放継手４０）
感熱開放継手４０とは、第１配管３０と第２配管５０との間における流路を閉鎖する閉鎖部と、所定量以上の熱を感知した場合に第１配管３０と第２配管５０との間における流路を開放する感知部と、をあわせ持つ装置である。閉鎖部のみを有する装置（例：一斉開放弁）や感知部のみを有する装置は感熱開放継手４０から除かれる。 (Thermal opening joint 40)
The heat-sensitive open joint 40 includes a closing portion that closes a flow path between the first pipe 30 and the second pipe 50, and the first pipe 30 and the second pipe 50 when a predetermined amount of heat is detected. And a sensing unit that opens the flow path between them. A device having only a closed portion (for example, a simultaneous opening valve) and a device having only a sensing portion are excluded from the heat-sensitive open joint 40.

感熱開放継手４０は屋内駐車場の天井面に設置される。具体的に説明すると、感熱開放継手４０は、例えば、０＜感熱開放継手４０と天井面との最短距離≦３０ｃｍの条件を満たすように設置される。自動車火災が生じると、自動車周辺の空気が暖められ天井面に向けた熱上昇気流が発生するが、天井面に達した熱上昇気流は天井面に沿って流動展開していく。したがって、感熱開放継手４０を屋内駐車場の天井面に設置すれば、屋内駐車場にて生じた火災をいち早く検知することができる。   The heat-sensitive open joint 40 is installed on the ceiling surface of the indoor parking lot. More specifically, the heat-sensitive open joint 40 is installed so as to satisfy the condition of 0 <the shortest distance between the heat-sensitive open joint 40 and the ceiling surface ≦ 30 cm, for example. When an automobile fire occurs, the air around the automobile is warmed and a heat rising airflow toward the ceiling surface is generated, but the heat rising airflow reaching the ceiling surface flows and develops along the ceiling surface. Therefore, if the heat sensitive open joint 40 is installed on the ceiling surface of the indoor parking lot, it is possible to quickly detect a fire that has occurred in the indoor parking lot.

感熱開放継手４０は、自動車の駐車位置（屋内駐車場が自動車の横幅・縦幅とほぼ同じ横幅・縦幅を有する駐車区画を有する場合には駐車区画。以下、同じ。）とは無関係に設置することもできるが、自動車の駐車位置を考慮した位置に設置されることが好ましく、特に、自動車の駐車位置の右側上方、左側上方、前側上方、または後側上方に設置されることが好ましい。自動車火災においては、自動車の内部に火源があることが多く、前述した熱上昇気流は、窓やエンジンルームなどがある自動車の右側、左側、前側、または後側にて生じやすい。したがって、上記の位置に感熱開放継手４０を設置すれば、屋内駐車場にて生じた火災をより早く検知することができる。   The heat-sensitive open joint 40 is installed regardless of the parking position of the automobile (the parking area if the indoor parking lot has a parking area having the same width and height as the width and length of the car. The same applies hereinafter). However, it is preferably installed at a position in consideration of the parking position of the automobile, and particularly preferably installed at the upper right side, the upper left side, the upper front side, or the upper rear side of the parking position of the automobile. In an automobile fire, there are many fire sources inside the automobile, and the above-described heat rising airflow is likely to occur on the right side, the left side, the front side, or the rear side of the automobile having a window or an engine room. Therefore, if the heat-sensitive open joint 40 is installed at the above position, a fire occurring in the indoor parking lot can be detected earlier.

（第２配管５０）
第２配管５０には例えば鋼管を用いることができる。第２配管５０は感熱開放継手４０を介して第１配管３０に接続される。第１配管３０と第２配管５０との間には、感熱開放継手４０が介在する限り、感熱開放継手４０以外の他の装置がさらに介在していてもよい。 (Second piping 50)
For example, a steel pipe can be used for the second pipe 50. The second pipe 50 is connected to the first pipe 30 via the heat sensitive open joint 40. As long as the heat-sensitive open joint 40 is interposed between the first pipe 30 and the second pipe 50, another device other than the heat-sensitive open joint 40 may further be interposed.

第２配管５０は屋内駐車場の天井面側から床面側へ向けて延伸する延伸部５０ａを備えている。このような延伸部５０ａを第２配管５０が備えることにより、開放型水噴霧ヘッド７０を自動車に近接する位置に設置することが可能となる。なお、第２配管５０は、延伸部５０ａとは別に、屋内駐車場の天井面に沿って設置される天井面沿い部５０ｂなどを備えていてもよい。   The 2nd piping 50 is provided with the extending part 50a extended | stretched toward the floor surface side from the ceiling surface side of an indoor parking lot. By providing the extending portion 50a with the second pipe 50, the open-type water spray head 70 can be installed at a position close to the automobile. In addition, the 2nd piping 50 may be provided with the ceiling surface along part 50b etc. installed along the ceiling surface of an indoor parking lot separately from the extending | stretching part 50a.

開放型水噴霧ヘッド７０を自動車に近接させることができる程度の長さを有する限り、延伸部５０ａの具体的な長さは特に限定されない。また、延伸部５０ａは、例えば、直線状、曲線状、あるいはこれらを組み合わせた様々な形状に形成することができる。   The specific length of the extending portion 50a is not particularly limited as long as it has a length that allows the open water spray head 70 to be close to the automobile. Moreover, the extending | stretching part 50a can be formed in various shapes which combined linear shape, curve shape, or these, for example.

（開放型水噴霧ヘッド７０：近接）
開放型水噴霧ヘッド７０とは感熱部を有さず出口が常に開放された水噴霧ヘッドをいう。開放型水噴霧ヘッド７０は、例えば、第２配管５０に接続されるノズルと、ノズルから噴射された水を散水するデフレクタと、を備えている。 (Open water spray head 70: proximity)
The open-type water spray head 70 refers to a water spray head that does not have a heat sensitive part and whose outlet is always open. The open-type water spray head 70 includes, for example, a nozzle connected to the second pipe 50 and a deflector that sprays water sprayed from the nozzle.

開放型水噴霧ヘッド７０は、第２配管５０の延伸部５０ａに接続され、自動車に近接する。このように、開放型水噴霧ヘッド７０が自動車に近接することにより、開放型水噴霧ヘッド７０から放出される水の水勢が空気抵抗などを受けて自動車に到達するまでの間に減じられてしまうことが防止される。   The open-type water spray head 70 is connected to the extending portion 50a of the second pipe 50 and is close to the automobile. Thus, when the open-type water spray head 70 is close to the automobile, the water force discharged from the open-type water spray head 70 is reduced until it reaches the automobile due to air resistance or the like. It is prevented.

開放型水噴霧ヘッド７０と自動車との近接の程度（開放型水噴霧ヘッド７０と自動車の最短距離）は、特に限定されるものではないが、好ましくは１ｃｍ以上２ｍ以下であり、より好ましくは３ｃｍ以上９０ｃｍ以下であり、さらに好ましくは４４ｃｍ以上４６ｃｍ以下であり、望ましくは４５ｃｍ程度である。最短距離がこれらの範囲内にあれば、開放型水噴霧ヘッド７０と自動車との緩衝を回避しつつ、自動車から噴き出る炎の火勢に負けない水勢でもって、自動車の内部にまで十分な量の水を到達させることができる。なお、開放型水噴霧ヘッド７０は、自動車に近接する限り、延伸部５０ａ中のどの部位に接続されてもよく、例えば、延伸部５０ａにおける延伸元側の部位に接続することもできるし、延伸先側の部位に接続することもできるし、延伸の先端に接続することもできる。   The degree of proximity between the open water spray head 70 and the automobile (the shortest distance between the open water spray head 70 and the automobile) is not particularly limited, but is preferably 1 cm or more and 2 m or less, more preferably 3 cm. It is 90 cm or less, more preferably 44 cm or more and 46 cm or less, and desirably about 45 cm. If the shortest distance is within these ranges, a sufficient amount of water can be introduced into the interior of the automobile with a water force that does not suffer from the fire of the flame ejected from the automobile while avoiding buffering between the open water spray head 70 and the automobile. Water can be reached. The open-type water spray head 70 may be connected to any part in the extending part 50a as long as it is close to the automobile. For example, the open water spray head 70 can be connected to a part on the stretching source side in the extending part 50a. It can also be connected to the front site, or it can be connected to the tip of stretching.

開放型水噴霧ヘッド７０の数は特に限定されず、１つ以上であればよい。例えば、本実施形態では、開放型水噴霧ヘッド７０として、２つの開放型水噴霧ヘッド７０（自動車の右側に設置される開放型水噴霧ヘッド７１、自動車の左側に設置される開放型水噴霧ヘッド７２）が設けられるものとするが、これは一例である。また、開放型水噴霧ヘッド７０は、例えば、自動車の右側と左側にそれぞれ設置することができるほか、前側と後側にそれぞれ設置することもできるし、右側、左側、前側、及び後側にそれぞれ設置することもできる。   The number of the open-type water spray heads 70 is not particularly limited as long as it is one or more. For example, in the present embodiment, as the open water spray heads 70, two open water spray heads 70 (an open water spray head 71 installed on the right side of the automobile and an open water spray head installed on the left side of the automobile). 72) is provided, but this is an example. Moreover, the open-type water spray head 70 can be installed, for example, on the right side and the left side of the automobile, respectively, and can also be installed on the front side and the rear side, respectively, and on the right side, the left side, the front side, and the rear side, respectively.

図４Ａは自動車に近接する開放型水噴霧ヘッドのデフレクタの模式的平面図であり、図４Ｂは図４Ａ中のＡ−Ａ断面図である。また、図５Ａは自動車の上方に設置される開放型（閉鎖型）水噴霧ヘッドのデフレクタの模式的平面図であり、図５Ｂは図５Ａ中のＢ−Ｂ断面図である。図４Ａ、図４Ｂ、図５Ａ、図５Ｂに示すように、自動車の上方に設置される開放型（閉鎖型）水噴霧ヘッド８０、９０のデフレクタＤ２の開き角度θ２は、自動車に近接する開放型水噴霧ヘッド７０のデフレクタＤ１の開き角度θ１より小さいことが好ましい。このようにすれば、自動車の上方に設置される開放型（閉鎖型）水噴霧ヘッド８０、９０の散水エリアが狭まるため、火源を有する自動車を包み込むよう、該自動車の上方から該自動車に向けてカーテン状に水を散水させることができる。また、自動車に近接する開放型水噴霧ヘッド７０の散水エリアが広がるため、隣接する自動車に向けても散水することが可能となり、隣接する自動車への延焼を効果的に防止することができる。 [Opening angle of deflector]
FIG. 4A is a schematic plan view of a deflector of an open-type water spray head close to an automobile, and FIG. 4B is a cross-sectional view taken along line AA in FIG. 4A. 5A is a schematic plan view of a deflector of an open type (closed type) water spray head installed above the automobile, and FIG. 5B is a cross-sectional view taken along line BB in FIG. 5A. As shown in FIGS. 4A, 4B, 5A and 5B, the opening angle θ2 of the deflector D2 of the open type (closed type) water spray heads 80 and 90 installed above the automobile is an open type close to the automobile. It is preferable that the opening angle θ1 of the deflector D1 of the water spray head 70 is smaller. In this way, the water spray area of the open (closed) water spray heads 80, 90 installed above the automobile is narrowed, so that the automobile having the fire source is wrapped from above the automobile toward the automobile. Water can be sprayed like a curtain. Further, since the water spray area of the open water spray head 70 adjacent to the automobile is widened, water can be sprayed toward the adjacent automobile, and the spread of fire to the adjacent automobile can be effectively prevented.
