Consequently, the heat invasion to a fireproof chamber and the like from the outer side can be prevented.

Description

[Detailed description of the invention] [Industrial application field] FIELD OF THE INVENTION The present invention relates to fireproof panels.

[Prior art] Conventionally, in order to make buildings etc. fireproof, fireproofing materials were used for the interior and exterior materials of buildings, etc., and heat insulating materials were placed between the interior and exterior materials. Was.

[Problems to be Solved by the Invention] However, when fireproofing materials and heat insulating materials are used to make buildings etc. fireproof, the following problems arise.

■ For example, when a fire breaks out on the outside of a building, fireproofing and insulation materials cannot completely block heat from entering the building, causing the temperature inside the building to rise.

■ Refractory materials and insulation materials are separate pieces, making installation difficult.

In view of the above-mentioned circumstances, it is an object of the present invention to provide a fireproof panel that can maintain a constant internal temperature and is easy to install.

[Means for Solving the Problem] The present invention provides a liquid-impermeable heat insulating layer, a cooling pipe formed on the surface of the heat insulating layer and stretched so as to cover the surface of the heat insulating layer, and the cooling pipe. a heat transfer cooling layer made of an inner skin material formed on the surface; a cooling liquid supply port formed at the starting end of the cooling pipe; a porous seepage cooling layer formed on the back side of the heat insulation layer; This relates to a fire-resistant panel characterized in that it is provided with a seepage pipe that is arranged at the boundary between the cooling layer and the seepage cooling layer, communicates with the terminal end of the cooling pipe, and has a coolant seep hole at the tip. be.

[For production] The heat transfer cooling layer is cooled by the cooling liquid flowing inside.

At least a portion of the cooling fluid flowing through the heat transfer cooling layer is guided to the seepage cooling layer via the seepage piping.

Then, the guided cooling liquid spreads through the porous oozing cooling layer by capillary action and moistening the oozing cooling layer.

Then, when heat is applied from the outside, the cooling liquid evaporates from the surface of the seepage cooling layer, and the latent heat of evaporation at this time removes the heat from the seep cooling layer, thereby cooling the seep cooling layer.

Heat is isolated from the heat transfer cooling layer and the seepage cooling layer by a heat insulating layer provided between them.

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

1 to 4 show an embodiment of the present invention.

Liquid-impermeable structural materials 2.3 such as aluminum plates and stainless steel plates are pasted on both sides of the heat insulating material 1 to form a liquid-impermeable heat insulating layer 4.
form.

For example, as shown in FIG.
A cooling pipe consisting of a main cooling pipe 5 extending along the bottom and one side of the main cooling pipe 5 and branch cooling pipes 6 connected at one end to the main cooling pipe 5 and stretched so as to cover the surface of the heat insulating layer 4. 7 is attached to form a heat transfer cooling layer 8. Attach a coolant supply port 9 such as a one-touch joint to the lower end of the main cooling pipe 5.

At the upper end of the main cooling pipe 5, a coolant connection port lO such as a one-touch joint that can be connected to the one-touch joint is installed.

An inner skin material 11 such as a decorative board is attached to the surface of the heat transfer cooling layer 8.

On the other hand, on the back side of the heat insulating layer 4, there is a porous material 12 such as ceramic paper made of fibrous 5102, and a heat-resistant/fire-resistant material such as stainless steel or heat-resistant composite material with many small holes 13 formed on the surface. A seepage cooling layer 17 is provided, which is formed by combining an outer covering material 14 having a water-resistant property with a spacer 15 in between so as to form a steam passage 16 between the two.

At the other end of the cooling pipe B, an extension part 18 is provided that extends from the upper side of the heat insulating layer 4 to the back side.

A plurality of seepage pipes 2o having coolant seepage holes 19 at their tips are connected to the extension portion 18, which are inserted into the boundary between the heat insulating layer 4 and the porous material 12.

The fireproof panel 2I having the above structure is attached to the frame 22 so that the inner skin material 11 is on the inside and the outer skin material 14 is on the outside to form a fireproof room 23, as shown in FIG. 5, for example.

As shown in Figs. 5 and 6, a copper coolant supply pipe 26 with holes 25 is wrapped around the outer periphery of a flexible pipe 24 such as a stainless steel corrugated pipe, and the outside is covered with a silica cloth or similar material. A heat-resistant flexible tube 28 covered with a liquid-permeable fireproof cloth 27 is provided, and the heat-resistant flexible tube 28 led from the outside is connected to the bottom of the fireproof chamber 23, and the heat-resistant flexible tube 28 is led from the outside through the heat-resistant flexible tube 28. A power supply cable 29 and a coolant supply pipe 30 separate from the above are guided into the fireproof chamber 23.

Then, either connect the coolant supply pipe 30 to the coolant supply port 9 of each fireproof panel 21 (at this time, close the coolant connection port 10 of each fireproof panel 21), or connect the coolant supply pipe 30 to the coolant supply port 9 of each fireproof panel 21, or 21 cooling pipes 7 are connected to the cooling liquid supply port 9 and the cooling liquid connection port lO, the cooling liquid supply pipe 30 is connected to the vacant cooling liquid supply port 9 of each fireproof panel 21 (at this time, The vacant coolant connection ports 10 of each fireproof panel 21 are kept closed).

Note that 31 is a cooling liquid, and 29 is an interior material that covers the surface of the heat transfer cooling layer 8 of the fireproof panel 18.

The operation will be explained below.

Under normal conditions, the coolant 31 is not allowed to flow into the coolant supply pipe 30 passed inside the heat-resistant flexible tube 28 and the coolant supply pipe 2B wrapped around the outer circumference of the flexible tube 24 of the heat-resistant flexible tube 28. I'll keep it.

In the event of a fire, the coolant 3 is supplied to the coolant supply pipe 26°30 manually by a fire alarm, etc. or by a person in charge of fire protection.
1 is played.

Then, in the heat-resistant flexible tube 28, the coolant 31 leaks from the hole 25 of the coolant supply pipe 26 wrapped around the outer circumference of the flexible tube 24, and the leaked coolant 31 passes through the liquid-permeable fireproof cloth 27. The stain spreads due to capillary action, moistening the entire surface of the fireproof cloth 27.

In this way, when the fireproof cloth 27 on the surface of the heat-resistant flexible tube 28 becomes wet, when the heat-resistant flexible tube 28 is exposed to the heat of a fire, the cooling liquid 31 evaporates from the surface of the fireproof cloth 27 and this Since the heat of the fireproof cloth 27 is taken away by the latent heat of evaporation,
Heat resistant flexible tube 28 is protected from heat. And coolant 3
1 is evaporated, the coolant 3I is replenished by capillary action, so as long as the amount of coolant 31 flowing into the coolant supply pipe 26 is appropriate, the fireproof cloth 27 will always be kept moist. kept in condition.

In this way, by protecting the heat-resistant flexible tube 28 from heat, stable supply of the coolant 31 to the fireproof chamber 23 via the coolant supply pipe 30 is ensured.

In the fireproof room 23, each fireproof panel 2 is connected from the coolant supply pipe 30.
A cooling liquid 31 is supplied to the cooling liquid supply port 9 of the cooling liquid 3.
1 flows through the main cooling pipe 5 and branch cooling pipe 6 of the cooling pipe 7, cools the heat transfer cooling layer 8, and cools the surface of the fireproof panel 2I, that is, the fireproof chamber 23.
maintains a constant internal temperature.

Thereafter, the coolant 31 is guided to the seepage pipe 20 via the extension 18 and is discharged from the coolant seep hole 19.

The discharged coolant 31 oozes out by capillary action and spreads into the porous material 12 of the cooling layer 17, and the ooze-out cooling layer 1
Moisten 7.

In this way, when the porous material 12 of the seepage cooling layer 17 becomes wet, when the fireproof chamber 23 is exposed to the heat of a fire, the cooling liquid 31 evaporates from the surface of the porous material 12 and the steam passage 16 The heat is discharged through the small holes 13 of the outer skin material 21, and the heat is absorbed from the cooling layer 17 by the latent heat of vaporization at this time, so that heat is prevented from entering the fireproof chamber 23 from the outside.

Moreover, since the heat insulating layer 4 is interposed between the seepage cooling layer 17 and the heat transfer cooling layer 8, internal and external heat is completely cut off.

In the present invention, since the seepage cooling layer 17 and the heat transfer cooling layer 8 are incorporated into the integrated fireproof panel 21, construction can be facilitated.

Since the fireproof room 23 described above can maintain a constant internal temperature, it is suitable for making an evacuation room or a computer room in case of a fire. Furthermore, an evacuation route in the event of a fire can be created by covering the passageway of the building with a fireproof panel 21.

FIG. 7 shows another embodiment of the present invention, in which a coolant jacket 35 in which coolant channels 33 and 34 are formed on both sides of a corrugated plate 32 is used as the heat transfer cooling layer 8.
The structure is the same as that of the previous embodiment except that a seepage pipe 20° is provided which penetrates the heat insulating layer 4 and reaches the porous material 12 of the cooling layer 17. can play.

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

[Effects of the Invention] As explained above, the fireproof panel of the present invention can provide various excellent effects as described below.

■ The seepage cooling layer, the heat insulation layer, and the heat transfer cooling layer can almost completely block the heat input from the seepage cooling layer side to the heat transfer cooling layer side, so if a fireproof room is constructed, it will be fireproof. The temperature inside the room can always be kept constant.

■ The seepage cooling layer, heat insulation layer, and heat transfer cooling layer are integrated, making construction easier.
