Description
【０００１】[0001]
本考案は火災発生時等の緊急時に、避難する人の安全を高温の熱から守るため の耐熱室に関するものである。 The present invention relates to a heat-resistant room for protecting the safety of evacuees from high-temperature heat in an emergency such as a fire.
【０００２】[0002]
近年、都市化により建造物が益々高層化する傾向にあり、このためにビル火災 による悲惨な人的災害が多く発生している。 In recent years, buildings have tended to rise in height due to urbanization, which has caused many tragic human disasters due to building fires.
【０００３】 従来より、こうした火災に対する安全対策として、煙感知や温度感知を行う火 災感知器やスプリンクラー或いは手動の消火機器等を設置したり、また避難用の 機器等を設置することが行われている。Conventionally, as a safety measure against such a fire, a fire detector for detecting smoke or temperature, a sprinkler, a manual fire extinguishing device, or the like has been installed, or an evacuation device or the like has been installed. ing.
【０００４】[0004]
しかし、火災感知器やスプリンクラーを備えていても、故障によって作動しな い危険性があり、更に火災感知器は火事が発生しても感知を行うのみで消火する 能力はなく、またスプリンクラーを設置した場合にも爆発的な火災に対しては充 分な消火を行えない場合があり、このために高層建築物の火災の場合火災が起こ っていない部屋等に避難することが行われるが、その場合にも隣接した部屋の火 災による熱によって避難した部屋の中の温度が短時間の内に高温となってしまい 大変危険となる問題がある。 However, even if a fire detector or sprinkler is provided, there is a risk that it will not operate due to a failure.Furthermore, the fire detector does not have the ability to extinguish only by detecting when a fire occurs, and the sprinkler is installed. In some cases, it may not be possible to fully extinguish an explosive fire, and in the case of a fire in a high-rise building, evacuation to a room where no fire has occurred may occur. Even in that case, there is a problem that the temperature in the room evacuated due to the heat of the fire in the adjacent room becomes high in a short time and becomes very dangerous.
【０００５】 又、避難用の機器等が種々考えられているが、安全でしかも効率良く避難でき る実用的に優れたものはなく、特に高層ビルでは高さが高いために避難中に落下 する等の二次的災害の発生の危険もある。[0005] Although various evacuation equipment and the like have been considered, there is no practically excellent one that can safely and efficiently evacuate, and especially in a high-rise building, it falls during evacuation because of its high height. There is also the risk of the occurrence of secondary disasters such as.
【０００６】 本考案は、上記従来の問題点に鑑みてなしたもので、建物内において火災の発 生により避難する人を、火災による高温の熱から安全に保護し得る耐熱室を提供 することを目的とする。The present invention has been made in view of the above conventional problems, and provides a heat-resistant room capable of safely protecting a person evacuating due to a fire in a building from high-temperature heat caused by the fire. With the goal.

本考案は、部屋の天井部、周壁部及び床部下側の夫々に、滲み出し冷却パネル を用いて天井冷却壁、側部冷却壁及び床下冷却壁を形成し、前記天井部内に給水 タンクを設け、該給水タンクを途中に開閉弁を有した給水管を介して前記天井冷 却壁、側部冷却壁及び床下冷却壁の滲み出し冷却パネルに接続したことを特徴と する耐熱室、に係るものである。 According to the present invention, a ceiling cooling wall, a side cooling wall, and an underfloor cooling wall are formed by using a seepage cooling panel on each of the ceiling portion, the peripheral wall portion, and the floor lower portion of a room, and a water supply tank is provided in the ceiling portion. A heat-resistant room characterized in that the water supply tank is connected to the seepage cooling panel of the ceiling cooling wall, the side cooling wall and the underfloor cooling wall via a water supply pipe having an opening / closing valve in the middle thereof Is.
【０００８】[0008]
本考案では、火災発生時に、滲み出し冷却パネルによって形成された天井冷却 壁、側部冷却壁及び床下冷却壁に給水タンクの水を供給すると、前記滲み出し冷 却パネルに水が滲み渡って耐熱室全体が湿り、従って火災の熱に晒されても耐熱 室の表面から水が蒸散することによりその蒸発潜熱により冷却が行われて、耐熱 室内への入熱が遮断され耐熱室内を低温に維持して安全を図ることができる。更 にこの時、断熱室の直上の天井部内に給水タンクを備えているので、給水管が焼 損するようなことを防止でき耐熱室内からの直接操作によっても給水タンクの水 を滲み出し冷却パネルに供給することができ、よって確実な断熱による安全を確 保することができる。 According to the present invention, when a fire occurs, when water in the water tank is supplied to the ceiling cooling wall, the side cooling wall, and the underfloor cooling wall formed by the seepage cooling panel, the seepage cooling panel is permeated with water and heat-resistant. Even if the entire room gets damp and therefore exposed to the heat of a fire, water evaporates from the surface of the heat-resistant room to cool it by the latent heat of vaporization, and the heat input to the heat-resistant room is shut off, keeping the heat-resistant room at a low temperature. You can achieve safety. Furthermore, at this time, since the water supply tank is installed in the ceiling part directly above the heat insulation room, it is possible to prevent the water supply pipe from being burnt out, and the water in the water supply tank can be exuded by a direct operation from the heat resistant room to form a cooling panel. It is possible to supply it, and thus to ensure safety through reliable heat insulation.

【００１０】 図１は本考案の一実施例を示すもので、ビルの所要の部屋に耐熱室１を構成す るようにしている。FIG. 1 shows an embodiment of the present invention, in which a heat-resistant room 1 is constructed in a required room of a building.
【００１１】 耐熱室１は、天井部２と、周壁部３と、床部４からなる部屋の形状を有してお り、前記天井部２に、滲み出し冷却パネル５を用いて所要の角度で傾斜させた天 井冷却壁６を形成する。該天井冷却壁６の最上端部には、該天井冷却壁６全面に 水を拡散供給するための給水ヘッダ７を設ける。The heat-resistant room 1 has the shape of a room consisting of a ceiling part 2, a peripheral wall part 3 and a floor part 4, and the ceiling part 2 is provided with a bleeding cooling panel 5 at a required angle. The tilted cooling wall 6 is formed. At the uppermost end of the ceiling cooling wall 6, a water supply header 7 for diffusing and supplying water to the entire surface of the ceiling cooling wall 6 is provided.
【００１２】 耐熱室１の直上の天井部２内（天井裏）に給水タンク８を設け、該給水タンク ８を給水管９を介して前記給水ヘッダ８に接続する。図中１０は、前記給水管９ に取付けられた開閉弁であり、該開閉弁１０は図示しない火災感知器からの感知 信号により自動的に開作動するようになっていても良いが、自動化されているい ないに関係なく、手動ハンドル１１により耐熱室１内から確実に開閉を行うこと ができるようになっている。又、前記天井部２の給水タンク８の下側には、給水 タンク８の外周面に結露した水滴を集める傾斜面１２を形成していると共に、該 傾斜面１２の最下端部に集められた水を外部に排出する排水管１３を接続してい る。A water supply tank 8 is provided in the ceiling 2 (above the ceiling) directly above the heat-resistant room 1, and the water supply tank 8 is connected to the water supply header 8 via a water supply pipe 9. Reference numeral 10 in the figure denotes an on-off valve attached to the water supply pipe 9, and the on-off valve 10 may be automatically opened by a detection signal from a fire detector (not shown). Regardless of whether or not it is used, the manual handle 11 can be used to reliably open and close the heat resistant chamber 1. Further, below the water supply tank 8 of the ceiling portion 2, there is formed an inclined surface 12 for collecting water droplets condensed on the outer peripheral surface of the water supply tank 8 and is collected at the lowermost end of the inclined surface 12. A drain pipe 13 for discharging water to the outside is connected.
【００１３】 前記周壁部３に、滲み出し冷却パネル５を用いて前記天井冷却壁６の下端部に 連続するように側部冷却壁１４を形成する。側部冷却壁１４の上端部にも給水ヘ ッダ７を設け、該給水ヘッダ７を給水管９を介して給水タンク８に接続し、更に 給水管９の途中に手動ハンドル１１を有した開閉弁１０を設ける。A side cooling wall 14 is formed on the peripheral wall portion 3 so as to be continuous with a lower end portion of the ceiling cooling wall 6 by using a seepage cooling panel 5. A water supply header 7 is also provided on the upper end of the side cooling wall 14, the water supply header 7 is connected to a water supply tank 8 via a water supply pipe 9, and the water supply pipe 9 has a manual handle 11 in the middle thereof for opening and closing. A valve 10 is provided.
【００１４】 更に前記床部４の床下には、前記周壁部３の側部冷却壁１４の下端に連続し、 且つ所要の傾斜を有した床下冷却壁１５を形成すると共に、該床下冷却壁１５の 下側に傾斜床面１６を形成して該傾斜床面１６の最下端に余剰の水を外部に排出 するための排水管１７を接続する。床下冷却壁１５の上端部にも給水ヘッダ７を 設け、該給水ヘッダ７を図示しない給水管を介して給水タンク８に接続すると共 に、給水管の途中に手動ハンドルを有した開閉弁を設ける。図中１８は耐熱室１ 内に備えられるベッド等の備品を示す。 前記給水タンク８は、図２に示すように天井部の傾斜面１２に有した支持突条 １９上に支持され床板２０を支持する桁材２１に沿って延びる形状を有しており 、補水管２２により常に一定レベル以上の水が給水タンク８内に保持されるよう にレベル計等を備えて調節されるようになっている。Further, under the floor of the floor portion 4, an underfloor cooling wall 15 is formed which is continuous with the lower end of the side cooling wall 14 of the peripheral wall portion 3 and has a required inclination, and the underfloor cooling wall 15 is formed. An inclined floor surface 16 is formed on the lower side of the above, and a drain pipe 17 for discharging excess water to the outside is connected to the lowermost end of the inclined floor surface 16. A water supply header 7 is also provided at the upper end of the underfloor cooling wall 15, the water supply header 7 is connected to a water supply tank 8 via a water supply pipe (not shown), and an opening / closing valve having a manual handle is provided in the middle of the water supply pipe. . Reference numeral 18 in the figure denotes equipment such as a bed provided in the heat-resistant room 1. As shown in FIG. 2, the water supply tank 8 has a shape that extends along a girder material 21 that supports a floor plate 20 and is supported on a support ridge 19 that is provided on the inclined surface 12 of the ceiling portion. 22 is provided with a level meter or the like so that water above a certain level is always kept in the water supply tank 8.
【００１５】 前記天井冷却壁６、側部冷却壁１２及び床下冷却壁１３を構成する滲み出し冷 却パネル５は、図３に示すように、不透水性の内側板２３の一側面に、板状の多 孔質材２４と、金網２５と、格子状の構造材２６とからなる滲み出し層２７を設 け、前記内側板２３と多孔質材２４との境界に、多数の滲み出し口２８を有して 複数に分岐する分散給水管２９を挿入配置して一体にした構成を有している。As shown in FIG. 3, the seepage cooling panel 5 that constitutes the ceiling cooling wall 6, the side cooling wall 12, and the underfloor cooling wall 13 has a plate on one side of the impermeable inner plate 23. A bleeding layer 27 composed of a porous material 24, a wire mesh 25, and a lattice-shaped structural material 26 is provided, and a large number of bleeding openings 28 are provided at the boundary between the inner plate 23 and the porous material 24. The distributed water supply pipe 29 that is branched into a plurality of parts is inserted and arranged to be integrated.
【００１６】 前記滲み出し冷却パネル５は内側板２３が耐熱室１の内側で、滲み出し層２７ が耐熱室１の外側になるように備えられる。又前記滲み出し冷却パネル５によっ て形成される前記天井冷却壁６、側部冷却壁１４、床下冷却壁１５は、全てが連 通された構成を有していても良い。 なお、上記耐熱室１には、空気供給装置あるいは煙遮断装置等の所要の設備を 同時に備えるようにしても良い。The exuding cooling panel 5 is provided such that the inner plate 23 is inside the heat resistant chamber 1 and the exudation layer 27 is outside the heat resistant chamber 1. Further, the ceiling cooling wall 6, the side cooling wall 14, and the underfloor cooling wall 15 formed by the seepage cooling panel 5 may all be connected to each other. The heat-resistant room 1 may be provided with required equipment such as an air supply device or a smoke blocking device at the same time.
【００１７】 火災が発生した際には、速やかに耐熱室１内に避難して扉等を閉める。火災が 発生すると、図示しない火災感知器からの火災感知信号により開閉弁が自動的に 開作動して給水タンク８の水が滲み出し冷却パネル５に所定量ずつ供給される。 又、開閉弁１０の自動開閉装置を備えていない場合、あるいは自動開閉装置の故 障により開作動が行われない場合は、直ちに手動ハンドル１１を操作して開閉弁 １０を開ける。When a fire occurs, immediately evacuate into the heat-resistant room 1 and close the door or the like. When a fire occurs, the open / close valve automatically opens in response to a fire detection signal from a fire detector (not shown), and the water in the water supply tank 8 seeps out and is supplied to the cooling panel 5 by a predetermined amount. If the opening / closing valve 10 is not provided with an automatic opening / closing device, or if the opening / closing operation is not performed due to a failure of the automatic opening / closing device, the manual handle 11 is immediately operated to open the opening / closing valve 10.
【００１８】 すると、上部給水タンク８内の水が給水管９を介して滲み出し冷却パネル５に よって形成された天井冷却壁６、側部冷却壁１４及び床下冷却壁１５に供給され 、前記滲み出し冷却パネル５に滲み渡り、耐熱室１の外周面全体が湿った状態と なる。Then, the water in the upper water supply tank 8 oozes out through the water supply pipe 9 and is supplied to the ceiling cooling wall 6, the side cooling wall 14 and the underfloor cooling wall 15 formed by the cooling panel 5, and the bleeding occurs. The heat spreads out to the cooling panel 5, and the entire outer peripheral surface of the heat resistant chamber 1 becomes wet.
【００１９】 これにより、耐熱室１が火災の熱に晒されても耐熱室１の表面から水が蒸散す ることによってその蒸発潜熱により外部からの熱を奪い、耐熱室１内への入熱を 遮断して耐熱室１内を低温に維持し安全を確保することができる。As a result, even if the heat-resistant chamber 1 is exposed to the heat of a fire, water evaporates from the surface of the heat-resistant chamber 1 to remove the heat from the outside by the latent heat of vaporization, and the heat input into the heat-resistant chamber 1 It is possible to keep the inside of the heat-resistant chamber 1 at a low temperature by shutting off the heat to ensure safety.
【００２０】 又、天井冷却壁６及び床下冷却壁１５が所要の傾斜角度で傾斜しており、その 最上端部に給水ヘッダ７を介して給水管９を接続するようにしているので、天井 冷却壁６及び床下冷却壁１５の水の廻りが非常に良好となる。また天井冷却壁が 傾斜していると、余剰の水が天井冷却壁６を伝って流れるために天井から水滴が 落下して室内を汚すことが防止されると共に、天井冷却壁６を伝った水はその後 側部冷却壁１３或いは床下冷却壁１３に伝って蒸散し、冷却に供されることにな るので水の有効な利用が図れる。Further, since the ceiling cooling wall 6 and the underfloor cooling wall 15 are inclined at a required inclination angle, and the water supply pipe 9 is connected to the uppermost end of the ceiling cooling wall 6 through the water supply header 7, the ceiling cooling wall is cooled. The water around the wall 6 and the underfloor cooling wall 15 becomes very good. Further, when the ceiling cooling wall is inclined, excess water flows along the ceiling cooling wall 6 to prevent water droplets from falling from the ceiling and polluting the room. After that, the heat will be transmitted to the side cooling wall 13 or the underfloor cooling wall 13 to evaporate and be used for cooling, so that effective use of water can be achieved.
【００２１】 又前記したように、天井部２に給水タンク８を備えていると、夏期時における 冷房効果を期待することができる。この場合、給水タンク８の外周面には結露が 生じるが、水滴を傾斜床面１６によって回収し配水管１７で外部に排出するよう にしているので、何等問題は生じない。Further, as described above, when the ceiling part 2 is provided with the water supply tank 8, the cooling effect in the summer can be expected. In this case, dew condensation occurs on the outer peripheral surface of the water supply tank 8, but since water drops are collected by the inclined floor surface 16 and discharged to the outside by the water pipe 17, no problem occurs.
【００２２】 通常の火災は、出火から３０分〜１時間で殆んど終了してしまうと言われてお り、従って前記給水タンク８は、耐熱室１の滲み出し冷却パネル５が乾燥しない ように３０分〜１時間供給し続けることができる容量を有していれば良い。又前 記給水タンク８の容量は少なくても消火活動による救出が行われるまでの間火災 の熱から隔絶できれば、救出による安全確保の可能性が非常に大きくなる。It is said that a normal fire is almost completed within 30 minutes to 1 hour after the fire started. Therefore, in the water tank 8, the seepage cooling panel 5 of the heat-resistant room 1 is prevented from drying. It is sufficient that it has a capacity capable of continuously supplying for 30 minutes to 1 hour. Also, even if the water tank 8 has a small capacity, if it can be isolated from the heat of the fire before the rescue by the fire fighting activity, the possibility of ensuring safety by the rescue becomes very large.
【００２３】 尚、本考案は上記実施例にのみ限定されるものではなく、本考案の要旨を逸脱 しない範囲内において種々変更を加え得ることは勿論である。It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
【００２４】[0024]
本考案の耐熱室によれば、滲み出し冷却パネルによって天井冷却壁、側部冷却 壁及び床下冷却壁を構成し、滲み出し冷却によって断熱を行うようにしているの で、故障等を生じることなく耐熱室内を確実に低温に保持して火災発生時に避難 する人の安全を図ることができ、耐熱室の直上の天井部内に給水タンクを設ける ようにしているので、給水管が焼損するようなことがなくしかも耐熱室内からの 直接の操作によって給水タンクの水を滲み出し冷却パネルに供給することができ るので、確実に作動させて断熱による安全を確保することができる。また給水タ ンクを天井部内に設けるようにしているので、スペースの有効利用を図ることが できる。 According to the heat-resistant chamber of the present invention, the ceiling cooling wall, the side cooling wall, and the underfloor cooling wall are configured by the seepage cooling panel, and the heat is provided by the seepage cooling, so that no failure occurs. It is possible to keep the heat-resistant room at a low temperature to ensure the safety of people who evacuate in the event of a fire, and the water supply tank is installed in the ceiling directly above the heat-resistant room, so the water supply pipe will not be burnt out. In addition, since the water in the water supply tank can be exuded and supplied to the cooling panel by direct operation from the heat resistant room, it can operate reliably and ensure safety by heat insulation. In addition, since the water supply tank is installed inside the ceiling, the space can be effectively used.
