尚、28は冷却液、28は耐火パネル18の伝熱冷却層８表
面を覆う内装材である。Reference numeral 28 denotes a coolant, and reference numeral 28 denotes an interior material that covers the surface of the heat transfer cooling layer 8 of the refractory panel 18.
以下、作動について説明する。 Hereinafter, the operation will be described.
平常時には、耐熱可撓管25内部に通した冷却液供給管
27、及び、耐熱可撓管25の可撓管21外周に巻付けた冷却
液供給管23には冷却液28を流さないようにしておく。In normal times, the coolant supply pipe passed through the heat-resistant flexible pipe 25
The coolant 28 is prevented from flowing through the coolant supply pipe 23 wound around the outer periphery of the flexible tube 27 of the heat-resistant flexible tube 25.
火災発生時には、火災報知器等と連動させて、或いは
防火責任者等が手動で冷却液供給管23,27に冷却液28を
流す。In the event of a fire, a fire engineer or the like manually flows the coolant 28 into the coolant supply pipes 23 and 27 in conjunction with a fire alarm or the like.
すると、先ず、耐熱可撓管25では、可撓管21外周に巻
付けた冷却液供給管23の孔22から冷却液28が漏出し、漏
出した冷却液28が透液性のある耐火布24に毛管現象によ
ってしみ拡がり、耐火布24全面を湿らせる。Then, first, in the heat-resistant flexible tube 25, the coolant 28 leaks out of the hole 22 of the coolant supply pipe 23 wound around the outer periphery of the flexible tube 21, and the leaked coolant 28 becomes a liquid-permeable fireproof cloth 24. It spreads by capillary action and moistens the entire surface of the refractory cloth 24.
このように、耐熱可撓管25表面の耐火布24が湿った状
態となると、耐熱可撓管25が火災の熱にさらされた時
に、耐火布24の表面から冷却液28が蒸発してこのときの
蒸発潜熱により耐火布24の熱が奪われるので、耐熱可撓
管25は熱から保護される。そして、冷却液28が蒸発して
いる耐火布24へは、毛管現象により冷却液28が補給され
て行くので、冷却液供給管23へ流す冷却液28の量が適正
である限り、常に耐火布24は湿った状態に保たれる。As described above, when the fire-resistant cloth 24 on the surface of the heat-resistant flexible tube 25 becomes wet, when the heat-resistant flexible tube 25 is exposed to the heat of a fire, the cooling liquid 28 evaporates from the surface of the fire-resistant cloth 24, and this is removed. Since the heat of the refractory cloth 24 is removed by the latent heat of evaporation, the heat-resistant flexible tube 25 is protected from the heat. The coolant 28 is replenished to the refractory cloth 24 where the coolant 28 is evaporated by capillary action, so that the refractory cloth always flows as long as the amount of the coolant 28 flowing to the coolant supply pipe 23 is appropriate. 24 is kept moist.
このように、耐熱可撓管25が熱から保護されることに
よって、冷却液供給管27を介して耐火室20への冷却液28

管７の主冷却管５と枝冷却管６を流れて伝熱冷却層８を
冷却し、耐火パネル18の表面即ち耐火室20の内部の温度
を一定に保つ。In the refractory chamber 20, a coolant 28 is supplied from the coolant supply pipe 27 to the coolant supply port 10 of each refractory panel 18, and the coolant 28 flows through the main cooling pipe 5 and the branch cooling pipe 6 of the cooling pipe 7 to be transmitted. The heat cooling layer 8 is cooled to keep the temperature of the surface of the refractory panel 18, that is, the temperature inside the refractory chamber 20 constant.
その後、冷却液28は延長部14を介してしみ出し用配管
17の分岐管16に導かれ、冷却液しみ出し孔15から排出さ

The liquid is guided to a branch pipe 16 of 17 and discharged from a coolant seepage hole 15.
排出された冷却液28は毛管現象によってしみ出し冷却
層４の多孔質材2,3にしみ拡がり、しみ出し冷却層４全
面を湿らせる。The discharged cooling liquid 28 exudes by the capillary phenomenon and spreads to the porous materials 2 and 3 of the cooling layer 4 to wet the entire exuding cooling layer 4.
このように、しみ出し冷却層４全面が湿った状態とな
ると、耐火室20が火災の熱にさらされた時に、しみ出し
冷却層４の表面から冷却液28が蒸発してこのときの蒸発
潜熱によりしみ出し冷却層４の表面から熱が奪われるの
で、耐火室20は外部からの入熱が防止される。As described above, when the entire surface of the exudation cooling layer 4 becomes wet, when the refractory chamber 20 is exposed to the heat of fire, the coolant 28 evaporates from the surface of the exudation cooling layer 4 and the latent heat of evaporation at this time. As a result, heat is removed from the surface of the exuding cooling layer 4, so that heat input from the outside into the refractory chamber 20 is prevented.
本発明では、冷却液28を、耐火室20内部の伝熱冷却層
８の冷却に用いた後、外部のしみ出し冷却層４の冷却に
用いるようにしているので、高い冷却効率を得ることが
できる。In the present invention, since the cooling liquid 28 is used for cooling the heat transfer cooling layer 8 inside the refractory chamber 20 and then for cooling the seepage cooling layer 4 outside, high cooling efficiency can be obtained. it can.
更に、しみ出し冷却層４と伝熱冷却層８を一体の耐火
パネル18に組み込んだので、施工を容易化することがで
きる。Further, since the seepage cooling layer 4 and the heat transfer cooling layer 8 are incorporated into the integral fireproof panel 18, the construction can be facilitated.
上記したような耐火室20は内部の温度を一定に保つこ
とができるので、火災時の避難室やコンピュータ室を作
るのに適している。又、建物の通路を耐火パネル18で覆
って火災時の避難通路を作ることもできる。The refractory room 20 as described above can keep the internal temperature constant, and thus is suitable for building an evacuation room or computer room in case of fire. In addition, the passage of the building can be covered with the fireproof panel 18 to form an evacuation passage in case of fire.

Various excellent effects as described below can be obtained.
しみ出し冷却層側から冷却管側への入熱を略完全に
遮断することができるので、耐火室を構成した場合には
耐火室内部の温度を常に一定に保持することができる。Since the heat input from the seepage cooling layer side to the cooling pipe side can be almost completely shut off, the temperature inside the refractory chamber can always be kept constant when the refractory chamber is configured.
