Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator.

[Conventional technology] When a fire breaks out in a high-rise building such as a high-rise building, victims located above the floor where the fire occurs are unable to use the stairs due to smoke and flames filling the intermediate floors. You may be forced to escape by elevator.

[Problem to be solved by the invention] However, in conventional elevators, even if it is possible to block fire and smoke to some extent and allow victims to escape, it is not possible to prevent heat from entering the elevator. There was a risk of being burned in the overheated elevator while escaping.

The present invention was made in view of the above-mentioned circumstances, and it is an object of the present invention to provide an elevator that protects disaster victims from the heat of a fire and allows them to escape safely.

[Means for Solving the Problems] The present invention provides reinforcement for the peripheral wall of an elevator main body that is moved in the vertical direction of a high-rise building by a lifting device, using a porous material, a water supply pipe that supplies water to the porous material, and reinforcement. A peripheral wall of an elevator main body that is moved in the vertical direction of a high-rise building by an elevator or a lifting device, and a wall surface of the high-rise building that faces the elevator main body, characterized by being constructed of a seepage cooling panel comprising a member The present invention relates to an elevator characterized in that it is constituted by a seepage cooling panel comprising a porous material, a water supply pipe for supplying water to the porous material, and a reinforcing member.

[Function] Accordingly, in the present invention, when water is supplied from the water supply device to the seepage cooling panel constituting the peripheral wall of the elevator main body, the water seeps into the seep cooling panel and spreads, moistening the surface of the elevator main body surrounding wall and absorbing the heat of the fire. When the elevator body is exposed to water, water evaporates from the surface of the peripheral wall of the elevator body and its latent heat of vaporization is taken away, thereby preventing heat from entering the elevator body from the outside.

Furthermore, if the wall surface of the high-rise building facing the elevator main body is configured with a seepage cooling panel, the wall surface of the high-rise building facing the elevator main body will be cooled by the same effect as described above, and the entry into the elevator main body from the outside will be prevented. Heat is further prevented.

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

1 to 5 show an embodiment of the elevator according to claim 1 of the present invention, in which four parts 2 extending vertically are formed on the outer wall of a high-rise building 1 such as a high-rise building, as shown in the figure. ,
In the recess 2, an elevator main body 4 whose peripheral wall is constituted by a seepage cooling panel 3, which will be described later, is disposed so as to be movable up and down. It is suspended and supported from the boarding room 6 via a wire 7.

Here, the upper end of the wire 7 is tied to the upper part of the emergency boarding room 6, and the lower end is wound around the winch drum 9 of the lifting device 8 installed on the upper part of the elevator main body 4. The elevator main body 4 can be moved up and down by winding and unwinding the wire 7 by the winch drum 9.

Furthermore, the structure of the seepage cooling panel 3 that constitutes the peripheral wall of the elevator main body 4 will be described in detail below.

As shown in FIGS. 3 and 4, water-impermeable structural materials 11 and 12 are pasted on both sides of a plate-shaped heat insulating material 10 to form a heat insulating layer 13.
A cooling pipe 14 stretched in a zigzag pattern is attached to the surface of the heat insulating layer 13 so as to cover the surface, and a plate-shaped porous material 15 is attached to the back surface of the heat insulating layer 13. and,
A seepage cooling layer 18 is formed by assembling a wire mesh 16 and a lattice-like structural material 17, and a plurality of seepage holes 19 are formed at the boundary between the heat insulating layer 13 and the seepage cooling layer 18. The seepage cooling panel 3 described above is constructed by inserting and arranging a water supply pipe 20 that branches into two, and connecting the base end of the water supply pipe 20 to the cooling pipe 14.

In addition, in the seep cooling panel 3 configured as described above, the heat insulating layer 13 is inside the elevator main body 4, and the seep cooling layer 1 is located inside the elevator body 4.
8 is the outer side of the elevator main body 4 to form the peripheral wall of the elevator main body 4.

Furthermore, an air cylinder 21 capable of supplying emergency air into the elevator main body 4 is connected to the cooling pipe 14 of the seepage cooling panel 3 via a valve (not shown) in the upper part of the elevator main body 4. A water tank 22, which is a water supply device that stores the required amount of water, is installed in each case (see Fig. 2).

Moreover, the high-rise building 1 is located at a required position of the elevator main body 4.
A water supply pipe 24 that connects one end of a heat-resistant cable 23 led from the outside and passes through the heat-resistant cable 23 to supply water to the water tank 22, and a power supply cable °25 that supplies current to the lifting device 8. Air supply pipes 2B for supplying air into the elevator main body 4 separately from the air cylinder 21 are respectively guided from the outside of the high-rise building 1 to the elevator main body 4.

The other end of the heat-resistant cable 23 may be connected to a rescue trailer 27 on the ground mounted near a high-rise building, for example, as shown in FIG. , an air pump, etc. are of course provided.

In the figure, 28 is a door for boarding, 29 is a door for escape, and 30 is a guide roller for raising and lowering the elevator main body 4 while preventing contact with the high-rise building 1.

The effect will be explained below.

During normal times, the wire 7 is connected to the winch drum 9 of the lifting device 8.
The elevator main body 4 is placed adjacent to the emergency boarding room 6 in a wound state.

In the event of a fire, victims in the high-rise building 1 evacuate to the roof 5, open the boarding door 28 from the emergency boarding room 6, enter the elevator body 4, open the valve of the air cylinder 21, and exit the elevator. By filling the inside of the main body 4 with fresh air, the internal pressure is made slightly higher than the external pressure to prevent smoke from entering, and the water seeps out by opening the valve of the water tank 22 and supplies water to the cooling pipe 14 of the cooling panel 3. .

The water supplied to the cooling pipe 14 seeps out to the cooling panel 3
While cooling the inner surface of the elevator body 4, the water supply pipe 2
0 and is discharged from the seepage hole 19, and the discharged water spreads through the porous material 15 of the seepage cooling layer 18 by capillary action and moistens the seepage cooling layer 18.

On the other hand, on the ground, the other end of the heat-resistant cable 23 is immediately connected to the rescue trailer 27, and electricity, water, and air are supplied to the elevator main body 4.

Once the heat-resistant cable 23 is connected to the rescue trailer 27,
The disaster victim inside the elevator main body 4 operates the elevator main body 4 to lower the elevator main body 4, and when it reaches the ground, opens the escape door 29 and escapes.

At this time, when the elevator main body 4 is exposed to the heat of the fire while descending, water evaporates from the surface of the porous material 15 of the seepage cooling panel 3, and its latent heat of evaporation causes water to seep out into the cooling layer 1.
Since heat is removed from the elevator body 8, heat input from the outside is prevented from entering the elevator body 4.

Moreover, since there is a heat insulating layer 13 inside the seepage cooling layer 18, heat between the inside and outside is almost completely cut off.

Therefore, according to the above, victims can be protected from the heat of the fire and safely evacuated.

In this embodiment, electricity is supplied from the rescue trailer 27 via the heat-resistant cable 23 because there is a risk that the power supply on the high-rise building 1 side will not be available in the event of a fire. Wire 7 using the power supply on the building 1 side
The elevating device for winding and rewinding is installed in the emergency boarding room 6.
It may also be provided on the upper part for combined use.

In addition, the reason why air and water are supplied from the rescue trailer 27 via the heat-resistant cable 23 is that if there are many victims and the elevator body 4 repeatedly transports the pistons, the air cylinder 21 and water tank 22 may be This is because the elevator main body 4 is not equipped with the air cylinder 21 and the water tank 22, and the rescue trailer 2 is directly operated.
It is also possible to use the air and water supplied from the rescue trailer 27, and in this case, the water pump of the rescue trailer 27 of course serves as the water supply device.

The heat-resistant cable 23 is wound up and unwound using a large drum, for example, which is formed by fitting a hollow cylindrical rotary part to which the end of the heat-resistant cable 23 is connected to the outer periphery of a cylindrical fixed part. The water, electric current, and air supplied to the cylindrical fixed part are passed through the rotating part to the water supply pipe 24 in the heat-resistant cable 23 and the power supply cable 2.
5. The air may be sent to the air supply pipe 26.

6 and 7 show an embodiment of the elevator according to claim 2 of the present invention, in which the elevator main body 4, which is constructed in substantially the same manner as the embodiment shown in FIGS. When the elevator is accommodated in the elevator vertical hole 31 formed inside the building 1 and raised or lowered, a large number of seeps occur on the inner wall surface of the elevator vertical hole 31, which is the wall surface of the high-rise building l facing the elevator main body 4. It is composed of cooling panels 3°, and each seepage cooling panel 3′ is connected via a valve 33 to a water tank 32, which is a water supply device provided on the roof 5 of the high-rise building 1.

The seepage cooling panel 3°, as shown in FIG.
A seepage cooling layer 18° is formed by assembling the seepage cooling layer 1g' with a large number of seepage holes 19' arranged in a zigzag pattern on the back side of the seepage cooling layer 1g' and arranged in a zigzag pattern. It is constructed by assembling a water-impermeable structural material 12' between the connected water supply pipes 20, and the seepage cooling layer I8° side of the seepage cooling panel 3' is on the inside, that is, on the elevator main body 4 side. Place it so that it is facing the same direction.

When the valve 33 of the water tank 32 is opened in the event of a fire, water is discharged from the seepage hole I9 of the water supply pipe 20', and the discharged water seeps out by capillary action and flows into the 18° cooling layer. The seepage spreads into the material 5 and moistens the seepage cooling layer I8°, so even if the middle of the elevator vertical shaft 31 is exposed to the heat of a fire, the surface of the porous material 15' of the seepage cooling panel 3' remains intact. Heat is taken away from the seepage cooling layer 18° by the latent heat of evaporation due to transpiration of water from the evaporation layer, making it possible to suppress the temperature rise inside the elevator vertical shaft 31.
Therefore, the safety of disaster victims inside the elevator main body 4 can be further improved.

The seepage cooling panel used in the present invention may have the structure shown in FIGS. 3 and 4 or the structure shown in FIG. 7, and basically consists of a porous material and a water supply pipe that supplies water to the porous material. , it is sufficient if there is a reinforcing member that maintains the shape and overall strength of the porous material and the water supply pipe by allowing water to evaporate from one side of the porous material, and the reinforcing member is shown in FIG. ,
In Figures 4 and 7, structural members 11°, 12°, 12°,
These are the wire mesh 16 and 18 degrees and the grid-like structural members 17 and 17 degrees.

Note that the elevator of the present invention is not limited to the above-mentioned embodiments, and the lifting device may be provided on the elevator main body side or on the high-rise building side, or may be provided on both sides and used in combination. The water supply device may be provided on the elevator main body side, the water supply device may be provided on the side of the high-rise building, or may be provided outside the high-rise building, and various other modifications may be made without departing from the gist of the present invention. Of course, modifications can be made.

[Effects of the Invention] As explained above, according to the elevator of the present invention, it is possible to prevent heat from entering the elevator body from the outside, thereby protecting victims from the heat of the fire and allowing them to escape safely. This has the excellent effect of being able to.
