[Industrial applications]

 The present invention relates to a heat-resistant room for protecting safety from high-temperature heat in an emergency such as a fire.

[0002]

[Prior Art]

 In recent years, buildings have tended to rise in height due to urbanization, which has caused many tragic human disasters due to building fires.

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]

[Problems to be solved by the device]

 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 such a case, it may not be possible to sufficiently extinguish an explosive fire.Therefore, it is necessary to evacuate to a room where no fire has occurred, but in that case as well There is a problem that the temperature inside the evacuated room becomes high in a short time due to the heat of the fire, which is very dangerous.

Although various devices for evacuation have been considered, there is no practically excellent one that can evacuate safely and efficiently. In a high-rise building, the height is high and the device falls during evacuation. There is also the risk of the occurrence of secondary disasters.

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.

[0007]

[Means for Solving the Problems]

 The present invention is directed to a side cooling wall and an underfloor cooling wall formed on a lower side of a peripheral wall and a floor using a seepage cooling panel, and a ceiling cooling attached to a ceiling at a required inclination angle using a seepage cooling panel. The present invention relates to a heat-resistant room comprising a wall and an upper water supply tank connected to the uppermost end of the ceiling cooling wall via a water supply pipe.

[0008]

[Action]

 According to the present invention, when water is supplied to the ceiling cooling wall, the side cooling wall and the underfloor cooling wall formed by the seepage cooling panel in the event of a fire, the water seeps into the seepage cooling panel and the entire heat-resistant room gets wet. Therefore, even when exposed to the heat of a fire, water evaporates from the surface of the heat-resistant chamber to remove the heat from the outside by the latent heat of vaporization, shut off the heat input to the heat-resistant room, and maintain the heat-resistant room at a low temperature. Can be planned. Also, since the ceiling cooling wall has the required inclination and the water supply pipe is connected to the uppermost end of the ceiling cooling wall, the water around the ceiling cooling wall is very well circumvented and excess water is supplied. Even if there is, the water drops are prevented from falling from the ceiling and polluting the room because it flows along the ceiling cooling wall, and the water that has propagated through the ceiling cooling wall oozes to the side cooling wall or the underfloor cooling wall. Water is effectively used because it evaporates and is used for cooling.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

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.

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. A water supply header 7 for diffusing and supplying water to the entire surface of the ceiling cooling wall 6 is provided at the uppermost end of the ceiling cooling wall 6, and the water supply header 7 is provided in a machine room directly above the heat-resistant room 1 or on the rooftop. It is connected to the upper water supply tank 8 via a water supply pipe 9. Reference numeral 10 in the drawing 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). Even if it is not automated, it can be opened and closed surely from inside the heat-resistant room 1 by the manual handle 11.

A side cooling wall 12 is formed on the peripheral wall portion 3 so as to communicate with the lower end portion of the ceiling cooling wall 6 by using a seepage cooling panel 5.

Further, under the floor of the floor portion 4, an underfloor cooling wall 13 that communicates with the side cooling wall 12 of the peripheral wall portion 3 and has a necessary inclination is formed, and the underfloor cooling wall 13 is The inclined floor surface 14 is formed on the lower side, and a drain pipe 15 for discharging excess water to the outside is connected to the lowermost end of the inclined floor surface 14.

As shown in FIG. 2, 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 16 as shown in FIG. A bleeding layer 20 composed of a porous multi-layered material 17, a wire mesh 18, and a lattice-shaped structural material 19 is provided, and a large number of bleeding openings 21 are provided at the boundary between the inner plate 16 and the porous material 17. The distributed water supply pipe 22 that branches into a plurality of parts is inserted and arranged to be integrated.

The exuding cooling panel 5 is provided such that the inner plate 16 is inside the heat resistant chamber 1 and the exudation layer 20 is outside the heat resistant chamber 1. The ceiling cooling wall 6, the side cooling wall 12, and the underfloor cooling wall 13, which are formed by the exuding cooling panel 5, may all be in communication with each other, or the ceiling cooling wall 6 and four surfaces. The side cooling wall 12 and the underfloor cooling wall 13 may be independent of each other and separately supplied with water. Reference numeral 23 in FIG. 1 denotes equipment such as a bed provided in the heat-resistant room 1.

In the event of a fire, immediately evacuate into the heat-resistant room 1 and close the door, etc., and then operate the manual handle 11 to open the on-off valve 10.

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 13, and the underfloor cooling wall 13 formed by the cooling panel 5, and the bleeding occurs. The heat spreads over the discharge cooling panel 5, and the entire outer peripheral surface of the heat resistant chamber 1 becomes wet.

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.

Further, the ceiling cooling wall 6 is inclined at a required inclination angle, and the water supply pipe 9 is connected to the uppermost end of the ceiling cooling wall 6 via the water supply header 7. Is very good, and since excess water flows along the ceiling cooling wall 6, it is possible to prevent water droplets from falling from the ceiling and pollute the room. After that, water is effectively used because it is transmitted to the side cooling wall 12 or the underfloor cooling wall 13 and evaporated to be used for cooling.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

[Effect of the device]

 According to the heat-resistant room of the present invention, since the ceiling cooling wall, the side cooling wall and the underfloor cooling wall are constituted by the seepage cooling panel, and the heat is provided by the seepage cooling, there is no trouble. The temperature inside the heat-resistant room can be maintained at a low temperature to ensure the safety of people who evacuate in the event of a fire, and the ceiling cooling wall is inclined at the required inclination angle, which allows good water circulation around the ceiling cooling wall. As the excess water flows along the ceiling cooling wall, it is possible to prevent water droplets from falling from the ceiling and polluting the room.At the same time, the excess water flows along the ceiling cooling wall to the side cooling walls. Since the water droplets are used for evaporation on the side cooling wall or the like, it is possible to exhibit excellent effects such as efficient use of water.
