Description

本発明は、散水設備に関する。詳しくは、構造物に設けられてこの構造物の外装部材に散水する散水設備に関する。   The present invention relates to watering equipment. Specifically, the present invention relates to a watering facility that is provided in a structure and sprays water on an exterior member of the structure.

従来より、構造物の外装部材に散水する散水設備が知られている（特許文献１参照）。散水設備は、例えば、建物の外壁面に沿って配置された配管と、この配管に所定間隔おきに設けられた散水ヘッドと、を備える。このような散水設備によれば、例えば夏季に、各散水ヘッドから構造物の外装部材に散水することで、この散水した水の気化熱により外装部材を冷却できる。よって、構造物周囲の気温を下げたり、構造物の内部に入る風の温度を下げたりして、ヒートアイランド現象を軽減できる。   Conventionally, a watering facility for watering an exterior member of a structure is known (see Patent Document 1). The watering facility includes, for example, piping arranged along the outer wall surface of a building, and watering heads provided on the piping at predetermined intervals. According to such a sprinkling facility, for example, in the summer season, the exterior member can be cooled by the heat of vaporization of the sprinkled water by spraying water from each watering head to the exterior member of the structure. Therefore, the heat island phenomenon can be reduced by lowering the temperature around the structure or lowering the temperature of the wind entering the structure.

ところで、従来の散水設備では、屋外で火災が発生した場合、散水により外装部材が湿潤状態となるものの、散水量が少ないため、火災の延焼を確実に防止するのは困難であった。   By the way, in the conventional watering equipment, when a fire occurs outdoors, although the exterior member becomes wet due to watering, it is difficult to reliably prevent the fire from spreading because the amount of watering is small.

本発明は、火災の延焼を確実に防止できる散水設備を提供することを目的とする。   An object of the present invention is to provide a watering facility that can reliably prevent the spread of fire.

請求項１に記載の散水設備は、構造物に設けられて当該構造物の外装部材に散水する散水設備であって、前記構造物に設けられた配管と、当該配管に水を供給する加圧送水装置と、前記配管に設けられて前記構造物の外部に露出する複数の散水ヘッドと、を備え、前記加圧送水装置を駆動して前記散水ヘッドから前記構造物の外装部材に散水し、火災が発生した場合には、火災発生箇所の近傍に位置する散水ヘッドから外部に向かって散水することを特徴とする。   The watering facility according to claim 1 is a watering facility which is provided in a structure and sprays water on an exterior member of the structure, and is provided with a pipe provided in the structure and a pressurized feed for supplying water to the pipe. A water device, and a plurality of watering heads provided on the pipe and exposed to the outside of the structure, and driving the pressurized water supply device to spray water from the watering head to the exterior member of the structure, When a fire occurs, water is sprayed from the watering head located in the vicinity of the fire occurrence point to the outside.

この発明によれば、例えば夏季には、各散水ヘッドから構造物の外装部材に散水することで、この散水した水の気化熱により外装部材を冷却できる。これにより、構造物周囲の気温を下げたり、構造物の内部に入る風の温度を下げたりして、ヒートアイランド現象を軽減できる。   According to the present invention, for example, in the summer, the exterior member can be cooled by the heat of vaporization of the sprinkled water by spraying water from each watering head to the exterior member of the structure. Thereby, the heat island phenomenon can be reduced by lowering the temperature around the structure or lowering the temperature of the wind entering the structure.

一方、火災が発生した場合には、火災発生箇所の近傍に位置する散水ヘッドから外部に向かって膜状に散水して、火の粉や放射熱などを防いだり、外装部材を湿らせて燃えにくくしたりして、火災の延焼を防止する。
このとき、常時散水用の散水ヘッドで火災用の散水ヘッドを兼用するので、火災用の散水ヘッドを個別に取り付ける場合に比べて、安価になる。
また、火災発生時に常時使用している散水ヘッドを使用するので、配管内に水を常時流通させているため、火災発生時に初めて故障や誤作動が発覚するということが少なくなる。よって、火災の延焼を確実に防止できる。 On the other hand, in the event of a fire, water is sprayed in the form of a film from the watering head located in the vicinity of the point where the fire occurred to prevent sparks and radiant heat, and the exterior members are moistened to make it difficult to burn. To prevent the spread of fire.
At this time, since the watering head for regular watering also serves as the watering head for fire, the cost is lower than when the watering head for fire is individually attached.
In addition, since the watering head that is always used in the event of a fire is used, water is constantly circulated in the pipe, so that it is less likely that a malfunction or malfunction will be detected for the first time when a fire occurs. Therefore, it is possible to reliably prevent the fire from spreading.

また、水を常時散水するために、配管に大きな貯水タンクを連結しておくことになる。よって、地震時に構造物の周囲で屋外火災が同時に多発して、多数の散水ヘッドで同時に散水することになっても、貯水タンクに大量の水を貯めているため、長時間に亘って散水できる。   In addition, in order to constantly spray water, a large water storage tank is connected to the pipe. Therefore, even if many outdoor fires occur around the structure at the time of an earthquake, and a large number of watering heads sprinkle simultaneously, a large amount of water is stored in the water storage tank, so water can be sprinkled for a long time. .

請求項２に記載の散水設備は、前記散水ヘッドは、前記配管に設けられて外周面に噴射孔が形成された筒状のヘッド部と、当該ヘッド部の内部に移動可能に設けられた移動弁と、前記ヘッド部の先端を塞いでかつ熱により溶融可能な蓋部と、当該蓋部に反力をとって前記移動弁を前記ヘッド部の基端側に向かって付勢する付勢部と、を備えることを特徴とする。   The watering facility according to claim 2, wherein the watering head is provided in the pipe and has a cylindrical head part having an injection hole formed on an outer peripheral surface thereof, and a movement provided in the head part so as to be movable. A valve, a lid portion that closes the tip of the head portion and can be melted by heat, and a biasing portion that biases the moving valve toward the proximal end side of the head portion by applying a reaction force to the lid portion And.

この発明によれば、付勢部により移動弁がヘッド部の基端側に向かって付勢されて、この移動弁により分岐配管の先端が塞がれる。この状態で、加圧送水装置を駆動して所定の水圧で配管内に水を供給すると、水圧により移動弁が付勢部の付勢力に抵抗してヘッド部の先端側に向かって移動し、ヘッド部内に水が流入して、噴射孔から水が噴射される。   According to this invention, the moving valve is urged toward the proximal end side of the head portion by the urging portion, and the distal end of the branch pipe is blocked by the moving valve. In this state, when the pressurized water supply device is driven and water is supplied into the pipe at a predetermined water pressure, the moving valve moves toward the front end side of the head portion against the urging force of the urging portion due to the water pressure, Water flows into the head portion and water is ejected from the ejection holes.

火災が発生すると、火災発生箇所の近傍に位置する散水ヘッドでは、火災の熱で蓋部が溶けて脱落し、移動弁に作用する付勢力が解除されるとともに、ヘッド部の先端が外部に開放される。よって、噴射孔に加えてヘッド部の先端から水が噴射される。
これにより、配管内の水圧が低下するため、火災発生箇所の近傍に位置していない散水ヘッドでは、付勢部により移動弁が押されてヘッド部の基端側に向かって移動し、この移動弁により分岐配管の先端が塞がれる。よって、ヘッド部内への水の流入が停止し、噴射孔からの水の噴射が停止する。 When a fire breaks out, the watering head located near the location of the fire will cause the lid to melt and fall off due to the heat of the fire, releasing the biasing force acting on the moving valve and opening the tip of the head to the outside Is done. Therefore, water is ejected from the tip of the head portion in addition to the ejection holes.
As a result, the water pressure in the pipe decreases, so in the watering head that is not located near the location of the fire, the moving valve is pushed by the urging unit and moves toward the base end side of the head unit. The valve closes the end of the branch pipe. Therefore, the inflow of water into the head portion is stopped, and the water injection from the injection hole is stopped.

以上より、ヘッド部、移動弁、蓋部、および付勢部を含んで散水ヘッドを構成することで、簡易な構造で、散水ヘッドから常時散水しつつ、火災発生時には、火災発生箇所の近傍に位置していない散水ヘッドの散水を停止しつつ、火災発生箇所の近傍に位置する散水ヘッドのみ外部に向かって散水して延焼を防止することが可能となる。
また、火災発生箇所の近傍に位置していない配管で弁が閉じていない場合でも、蓋部によりヘッド部内への水の流入が止まるため、火災発生箇所のみにより確実に散水できるようになる。 From the above, by constructing the watering head including the head part, the moving valve, the lid part, and the urging part, with a simple structure, always watering from the watering head, in the event of a fire, in the vicinity of the fire occurrence point While stopping the watering of the watering heads that are not located, only the watering heads located in the vicinity of the fire occurrence point can be watered outward to prevent the spread of fire.
In addition, even when the valve is not closed by piping that is not located in the vicinity of the fire occurrence location, the inflow of water into the head portion is stopped by the lid, so that water can be reliably sprayed only from the fire occurrence location.

この発明によれば、例えば夏季には、各散水ヘッドから構造物の外装部材に散水することで、この散水した水の気化熱により外装部材を冷却できる。これにより、構造物周囲の気温を下げたり、構造物の内部に入る風の温度を下げたりして、ヒートアイランド現象を軽減できる。一方、火災が発生した場合には、火災発生箇所の近傍に位置する散水ヘッドから外部に向かって膜状に散水して、火の粉や放射熱などを防いだり、外装部材を湿らせたりして、火災の延焼を防止する。このとき、外装部材に散水することで配管内に水を常時流通させているため、火災発生時に初めて故障や誤作動が発覚するということが少なくなる。また、水を常時散水するために、配管に大きな貯水タンクを連結しておくことになる。よって、地震時に構造物の周囲で屋外火災が同時に多発して、多数の散水ヘッドで同時に散水することになっても、貯水タンクに大量の水を貯めているため、長時間に亘って散水できる。   According to the present invention, for example, in the summer, the exterior member can be cooled by the heat of vaporization of the sprinkled water by spraying water from each watering head to the exterior member of the structure. Thereby, the heat island phenomenon can be reduced by lowering the temperature around the structure or lowering the temperature of the wind entering the structure. On the other hand, in the event of a fire, water is sprayed in the form of a film from the watering head located near the location of the fire to prevent fire sparks and radiant heat, etc. Prevent the spread of fire. At this time, since water is constantly circulated in the piping by sprinkling water on the exterior member, it is less likely that a failure or malfunction is detected for the first time when a fire occurs. In addition, in order to constantly spray water, a large water storage tank is connected to the pipe. Therefore, even if many outdoor fires occur around the structure at the time of an earthquake, and a large number of watering heads sprinkle simultaneously, a large amount of water is stored in the water storage tank, so water can be sprinkled for a long time. .

図１は、本発明の一実施形態に係る散水設備が適用された構造物としての建物１の構造を示す模式図である。
建物１には、外壁面２に沿って外装部材としての木製のルーバー１０が設けられている。
この建物１には、散水設備としての散水システム２０が設けられている。この散水システム２０は、建物１の内部を通り外壁面２に沿って各階毎に略水平に延びる配管２１と、この配管２１に連結された大型の貯水タンク２２と、建物１の内部に設けられて貯水タンク２２内の水を配管２１に供給する加圧送水装置としての送水ポンプ２３と、配管２１に設けられた複数の散水ヘッド３０と、を備える。 Drawing 1 is a mimetic diagram showing the structure of building 1 as a structure to which watering equipment concerning one embodiment of the present invention was applied.
The building 1 is provided with a wooden louver 10 as an exterior member along the outer wall surface 2.
The building 1 is provided with a watering system 20 as watering equipment. The watering system 20 is provided inside the building 1, a pipe 21 that passes through the inside of the building 1 and extends substantially horizontally along the outer wall 2 for each floor, a large water tank 22 connected to the pipe 21, and the building 1. A water supply pump 23 as a pressurized water supply device that supplies water in the water storage tank 22 to the pipe 21, and a plurality of watering heads 30 provided in the pipe 21.

図２〜図４は、ルーバー１０の横断面図、正面図、および縦断面図である。
ルーバー１０は、所定間隔おきに設けられた複数の木製の羽板１１で構成される。散水ヘッド３０は、これら羽板１１同士の間に設けられて、建物１の外部に露出している。 2 to 4 are a cross-sectional view, a front view, and a vertical cross-sectional view of the louver 10.
The louver 10 is composed of a plurality of wooden slats 11 provided at predetermined intervals. The watering head 30 is provided between the slats 11 and is exposed to the outside of the building 1.

図５は、散水ヘッド３０の断面図である。
羽板１１同士の間では、配管２１から分岐して分岐配管２１１が延びている。散水ヘッド３０は、各分岐配管２１１の先端に取り付けられている。
散水ヘッド３０は、分岐配管２１１の先端に設けられて外周面に噴射孔３１１が形成された筒状のヘッド部３１と、このヘッド部３１の内部に移動可能に設けられた移動弁３２と、ヘッド部３１の先端を塞いでかつ熱により溶融可能な蓋部３３と、この蓋部３３に反力をとって移動弁３２をヘッド部３１の基端側に向かって付勢する付勢部としてのばね部材３４と、を備える。 FIG. 5 is a cross-sectional view of the watering head 30.
Between the blades 11, a branch pipe 211 extends from the pipe 21. The watering head 30 is attached to the tip of each branch pipe 211.
The watering head 30 is provided at the tip of the branch pipe 211 and has a cylindrical head portion 31 having an injection hole 311 formed on the outer peripheral surface thereof, and a moving valve 32 provided movably inside the head portion 31. A lid portion 33 that closes the tip of the head portion 31 and can be melted by heat, and a biasing portion that urges the movement valve 32 toward the proximal end side of the head portion 31 by applying a reaction force to the lid portion 33. The spring member 34 is provided.

ヘッド部３１の基端側は、分岐配管２１１に連結されている。また、ヘッド部３１の先端面には、貫通孔３１２が形成されており、蓋部３３はこの貫通孔３１２に係止している。
移動弁３２は、分岐配管２１１の内径よりも大きい外径を有しており、ヘッド部３１の軸方向に沿って移動可能となっている。この移動弁３２は、ばね部材３４によりヘッド部３１の基端側に向かって付勢されて、分岐配管２１１の先端を塞いでいる。 The proximal end side of the head portion 31 is connected to the branch pipe 211. In addition, a through hole 312 is formed on the distal end surface of the head portion 31, and the lid portion 33 is engaged with the through hole 312.
The movement valve 32 has an outer diameter larger than the inner diameter of the branch pipe 211 and is movable along the axial direction of the head portion 31. The moving valve 32 is urged toward the proximal end side of the head portion 31 by the spring member 34 and closes the distal end of the branch pipe 211.

以上の散水システム２０は、以下のように動作する。
例えば夏季には、図１〜図４に示すように、送水ポンプ２３を駆動して、貯水タンク２２に貯めた水を散水ヘッド３０からルーバー１０の羽板１１に散水する。この噴射された水は、羽板１１の表面を伝って下方に流れ、この水の気化熱によりルーバー１０を冷却する。 The above watering system 20 operates as follows.
For example, in the summer, as shown in FIGS. 1 to 4, the water pump 23 is driven to spray water stored in the water storage tank 22 from the water spray head 30 onto the slats 11 of the louver 10. The jetted water flows downward along the surface of the slat 11 and cools the louver 10 by the heat of vaporization of the water.

具体的には、平常時で散水しない場合においても、送水ポンプ２３を駆動して、貯水タンク２２に貯めた水を水圧Ｐ０で配管２１内に供給しておく。この水圧Ｐ０は、移動弁３２が移動しない程度の水圧である。
そして、夏季などに散水したい場合には、送水ポンプ２３を駆動して、Ｐ０よりも大きい水圧Ｐ１で配管２１内に水を供給する。すると、図６に示すように、水圧により移動弁３２がばね部材３４の付勢力に抵抗してヘッド部３１の先端側に向かって移動し、ヘッド部３１の内部に水が流入して、噴射孔３１１から水が噴射される。 Specifically, even when water is not sprayed in normal times, the water pump 23 is driven to supply the water stored in the water storage tank 22 into the pipe 21 at the water pressure P 0 . This water pressure P 0 is a water pressure at which the moving valve 32 does not move.
And when watering is desired in the summer, etc., the water supply pump 23 is driven to supply water into the pipe 21 at a water pressure P 1 greater than P 0 . Then, as shown in FIG. 6, the moving valve 32 resists the urging force of the spring member 34 due to the water pressure and moves toward the front end side of the head portion 31, and water flows into the head portion 31 to cause the injection. Water is injected from the hole 311.

一方、屋外火災が発生した場合には、図７〜図１０に示すように、火災発生箇所の近傍に位置する散水ヘッド３０から外部に向かって膜状に散水するとともに、火災発生箇所の近傍に位置していない散水ヘッド３０の散水を停止する。   On the other hand, when an outdoor fire occurs, as shown in FIGS. 7 to 10, water is sprayed in the form of a film from the watering head 30 located in the vicinity of the fire occurrence point to the outside, and in the vicinity of the fire occurrence point. Stop watering of the watering head 30 which is not located.

具体的には、屋外で火災が発生すると、火災発生箇所の近傍に位置する散水ヘッド３０では、図１１に示すように、火災の熱で蓋部３３が溶けて脱落し、移動弁３２に作用する付勢力が解除されるとともに、ヘッド部３１の先端が外部に開放される。よって、噴射孔３１１に加えてヘッド部３１の先端の貫通孔３１２から水が大量に噴射される。貫通孔３１２から噴射された水は、建物１の外部に向かって大きく飛散する。   Specifically, when a fire occurs outdoors, in the watering head 30 located in the vicinity of the fire occurrence point, the lid 33 melts and falls off due to the heat of the fire, as shown in FIG. The urging force to be released is released, and the tip of the head portion 31 is opened to the outside. Therefore, a large amount of water is ejected from the through hole 312 at the tip of the head portion 31 in addition to the ejection hole 311. The water sprayed from the through hole 312 greatly scatters toward the outside of the building 1.

これにより、配管２１内の水圧がＰ０以下に低下するため、火災発生箇所の近傍に位置していない散水ヘッド３０では、図１２に示すように、ばね部材３４により移動弁３２が押されてヘッド部３１の基端側に向かって移動し、この移動弁３２により分岐配管２１１の先端が塞がれる。よって、ヘッド部３１の内部への水の流入が停止して、噴射孔３１１からの水の噴射が停止する。 As a result, the water pressure in the pipe 21 is lowered to P 0 or less, and therefore, in the watering head 30 that is not located in the vicinity of the fire occurrence point, the moving valve 32 is pushed by the spring member 34 as shown in FIG. It moves toward the proximal end side of the head portion 31, and the distal end of the branch pipe 211 is closed by the movement valve 32. Accordingly, the inflow of water into the head portion 31 is stopped, and the water injection from the injection hole 311 is stopped.

本実施形態によれば、以下のような効果がある。
（１）例えば夏季には、各散水ヘッド３０から建物１のルーバー１０に散水することで、この散水した水の気化熱によりルーバー１０を冷却できる。これにより、建物１の周囲の気温を下げたり、建物１の内部に入る風の温度を下げたりして、ヒートアイランド現象を軽減できる。 According to this embodiment, there are the following effects.
(1) For example, in the summer season, the louver 10 can be cooled by the heat of vaporization of the sprinkled water by sprinkling water from each sprinkling head 30 to the louver 10 of the building 1. Thereby, the heat island phenomenon can be reduced by lowering the temperature around the building 1 or lowering the temperature of the wind entering the building 1.

一方、屋外で火災が発生した場合には、火災発生箇所の近傍に位置する散水ヘッド３０から外部に向かって膜状に散水して、火の粉や放射熱などを防いだり、ルーバー１０を湿らせて燃えにくくしたりして、火災の延焼を防止する。
このとき、常時散水用の散水ヘッド３０で火災用の散水ヘッドを兼用するので、火災用の散水ヘッドを個別に取り付ける場合に比べて、安価になる。
また、火災発生時に常時使用している散水ヘッド３０を使用するので、配管２１内に水を常時流通させているため、火災発生時に初めて故障や誤作動が発覚するということが少なくなる。よって、火災の延焼を確実に防止できる。 On the other hand, when a fire occurs outdoors, water is sprayed in the form of a film from the watering head 30 located in the vicinity of the location where the fire has occurred to prevent sparks and radiant heat, or to moisten the louver 10. Prevent fire from spreading by making it difficult to burn.
At this time, since the watering head 30 for regular watering also serves as the watering head for fire, it is less expensive than the case where the watering head for fire is individually attached.
Further, since the watering head 30 that is always used in the event of a fire is used, water is constantly circulated in the pipe 21, so that it is less likely that a malfunction or malfunction will be detected for the first time when a fire occurs. Therefore, it is possible to reliably prevent the fire from spreading.

また、水を常時散水するために、配管２１に大きな貯水タンク２２を連結しておくことになる。よって、地震時に建物１の周囲で屋外火災が同時に多発して、多数の散水ヘッド３０で同時に散水することになっても、貯水タンク２２に大量の水を貯めているため、長時間に亘って散水できる。   In addition, a large water storage tank 22 is connected to the pipe 21 in order to constantly spray water. Therefore, even if an outdoor fire frequently occurs around the building 1 at the time of an earthquake and a large number of watering heads 30 spray water at the same time, since a large amount of water is stored in the water storage tank 22, Can spray water.

（２）ヘッド部３１、移動弁３２、蓋部３３、およびばね部材３４を含んで散水ヘッドを構成することで、簡易な構造で、散水ヘッドから常時散水しつつ、屋外火災発生時には、火災発生箇所の近傍に位置していない散水ヘッド３０の散水を停止しつつ、火災発生箇所の近傍に位置する散水ヘッド３０のみ外部に向かって散水して延焼を防止することが可能となる。
また、火災発生箇所の近傍に位置していない配管で弁が閉じていない場合でも、蓋部３３によりヘッド部３１の内部への水の流入が止まるため、火災発生箇所のみにより確実に散水できるようになる。 (2) By constructing the watering head including the head portion 31, the moving valve 32, the lid portion 33, and the spring member 34, a simple structure is used. While stopping the watering of the watering heads 30 that are not located in the vicinity of the location, only the watering heads 30 located in the vicinity of the fire occurrence location can be sprinkled outward to prevent the spread of fire.
In addition, even when the valve is not closed by piping that is not located near the fire occurrence location, the inflow of water into the head portion 31 is stopped by the lid 33, so that water can be reliably sprayed only from the fire occurrence location. become.

（３）ルーバー１０を木製とした。木製のルーバーは延焼しやすいが、建物１の周囲に屋外火災が発生しても、散水ヘッド３０から水を噴射して水幕を形成することで、ルーバー１０が延焼するのを確実に防止できる。さらに、ルーバー１０の材料として国産木材を使用すれば、地球環境保護に貢献できる。   (3) The louver 10 was made of wood. Although the wooden louver is easy to spread, even if an outdoor fire occurs around the building 1, it is possible to reliably prevent the louver 10 from spreading by spraying water from the watering head 30 to form a water curtain. .
