Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator for ultra-high-rise buildings, which can adjust the pressure difference between the inside and outside of the elevator shaft in the ultra-high-rise buildings.

[0002]

2. Description of the Related Art In conventional elevators, the internal and external pressures fluctuate according to the atmospheric pressure, and therefore, there is a drawback that "ear ears" occur when moving to high floors at high speed. 100 in future
If a 0m class ultra-high-rise building is to be realized, a pressure difference that is several times that of conventional high-rise buildings will occur, and countermeasures will be required.

[0003]

By the way, 1000 m
In a super high-rise building of the class, if the air pressure difference between the ground and the upper layers becomes remarkable and the movement is slow, it is considered that there is no problem for ordinary people, but for people who have a bad nose or who have a defective ear, In some cases, even a slight change in atmospheric pressure poses a problem. In addition, even when a normal person rises or descends rapidly, "ear ears" occur.

In the case of an ultra-high-rise building, it is considered preferable to divide the block into blocks according to the height and to apply air pressure on the ground floor to each air pressure block. The pressure difference is about several mb to several tens of mb, and a large blower is enough. In this case, the elevator shaft, the emergency staircase, the facility shaft, and the like that penetrate vertically have a problem because the pressure difference between the interior and the interior becomes large. The emergency stairs and equipment shafts should be separated by air pressure blocks, and an airlock should be installed if necessary.

However, when operating the elevator shaft by dividing it into compressed air blocks, it suffices to attach an airlock (or revolving door) to the top floor of the compressed air block, but if all floors are installed, When operating with the elevator, it is necessary to install an airlock at each entrance or exit or an airlock through which the elevator can pass at the top floor of the pressure block.

The present invention solves the above problems, and provides an elevator for an ultra-high-rise building that can adjust the atmospheric pressure difference between the inside and outside of the elevator shaft and can operate all floors with a single elevator. The purpose is to do.

[0007]

Therefore, the invention described in claim 1 of the present invention is to elevate and lower the inside of an elevator shaft 4 by a wire 2 in an ultra-high-rise building in which a building is divided into blocks to form a pneumatic block. Elevator body 3, a bag-shaped gasket 10 provided around the entrance / exit 7 of the elevator shaft 3, and the elevator shaft 3
And a pressing device 11 provided on the side opposite to the entrance / exit 7 of the elevator, and when the entrance / exit of the elevator is stopped, the pressing device 11 is provided.
The elevator main body 3 is pressed by the above, and high pressure air is supplied to the bag-shaped gasket 10 to airlock the entrance / exit 7.

Further, according to a second aspect of the present invention, in an ultra-high-rise building in which a building is divided into blocks to form a compressed air block, an elevator main body 3 that moves up and down in an elevator shaft 4 by a linear motor, and an elevator. Sealing members 19 and 2 provided on the upper and lower parts of the main body 3
0, and opening / closing doors 16 and 17 which are arranged at the upper and lower portions of the entrance / exit 7 on the uppermost floor of the pressure block in the elevator shaft 4 and which are opened / closed in conjunction with the passage of the elevator main body. Is air-locked for each pressure block.

The numbers added to the above-mentioned constitutions are for comparison with the drawings for easy understanding, and the constitutions of the present invention are not limited thereto.

[0010]

According to the present invention, in an ultra-high-rise building in which a building is divided into blocks to form a compressed air block, in the case of an elevator that moves up and down in the elevator shaft by a wire, the entrance / exit is air-locked and the linear motor is used in the elevator shaft. In the case of an elevator that moves up and down, airlock each air pressure block.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the atmospheric pressure distribution in an ultra-high-rise building of the present invention. In the case of an ultra-high-rise building, a pressure difference occurs according to the altitude. For example, in an ultra-high-rise building with an altitude of 1000 m, the atmospheric pressure difference is 114 mb. For example, the entire building is divided into blocks every 200 m as shown in FIG. Further, it is necessary that the pressure is increased by a large blower to increase the pressure to form a pressure block, and the pressure difference is set to several mb to several tens of mb. However, since the interior of the elevator shaft is a continuous space, it is necessary to hermetically seal the elevator shaft and the elevator so that the passenger does not feel a pressure difference when getting on and off.

FIG. 2 is a sectional view showing an embodiment of the elevator for an ultra-high-rise building of the present invention. This embodiment shows a method of suspending an elevator 1 with a wire 2 and moving it up and down.
The elevator body 3 is suspended in the elevator shaft 4 by the wire 2, and the elevator inner door 5 is packed 6
Sealed with. At the entrance / exit 7 of the elevator shaft 4, an elevator outer door 9 sealed by packing 8 is provided. A bag-shaped gasket 10 made of an elastic material such as rubber is fixed around the entire inside of the entrance / exit 7 of the elevator shaft 4. A bag-shaped jack 11 made of an elastic material such as rubber is fixed to the side of the elevator shaft 4 opposite to the entrance / exit 7. The bag-shaped jack 11 includes a piston driven by air or hydraulic pressure,
In short, any pressing device that presses the elevator body 3 may be used.

A high-pressure air pipe 12 for supplying high-pressure air is connected to the bag-shaped gasket 10 and the bag-shaped jack 11 and is configured to be normally compressed by a spring 13. In addition, a low-pressure air pipe 14 that supplies low-pressure air for equalizing the pressure in the passenger compartment is provided between the elevator inner door 5 and the elevator outer door 9. Reference numeral 15 denotes an auxiliary preload device, which preloads the interior of the elevator body 3 as necessary.

The operation of the present invention having the above-described structure will be described. When the elevator 1 stops at the entrance / exit 7, the high-pressure air is sent from the high-pressure air pipe 12 to the bag-shaped gasket 10 and the bag-shaped jack 11, and the elevator main body. 3 The air between the front surface of the elevator 3 and the elevator shaft 4 is hermetically closed, and at the same time, the air for lowering the pressure inside the room is sent from the low pressure air pipe 14 between the inner door 5 of the elevator and the outer door 9 of the elevator. The gasket is pressed in the direction of 10.
Therefore, while the elevator is stopped, the entrance / exit 7 is air-locked to the elevator shaft 4 to have an airtight structure.

A seal is attached to the portion of the bag-shaped gasket 10 that comes into contact with the elevator body 3 so as to complete the airtightness. However, if the blower to pressurize the room has a sufficiently large capacity, some air leakage is a particular problem. Don't

FIG. 3 is a sectional view showing another embodiment of the elevator for an ultra-high-rise building according to the present invention. The same components as those in the embodiment of FIG. 2 are designated by the same reference numerals and the description thereof will be omitted. This embodiment shows a method of driving the elevator 1 by a linear motor.

Since the elevator driven by the linear motor does not have a wire, it is possible to provide air pressure in the elevator shaft 4 by providing an airlock for each air pressure block of the building. That is, the upper opening / closing door 16 and the lower opening / closing door 17 are arranged above and below the entrance / exit 7 of the elevator shaft 4 at the entrance / exit 7 on the uppermost floor of the pressure block provided with the airlock.
Between the upper opening / closing door 16 and the lower opening / closing door 17, a compressed air supply port 1
8 is provided. Further, the gap between the elevator main body 3 and the elevator shaft 4 is made as small as possible, and the seal members 19 and 20 are provided on the upper and lower portions of the elevator main body 3.

The operation of the above embodiment will be described. When the elevator 1 passes through the entrance / exit 7 on the entry / exit floor where the airlock is installed, the speed is once reduced and the upper opening / closing door 16 and the lower opening / closing door 17 are opened and closed to make an elevator. To let air pass through and eliminate air loss as much as possible. Therefore, there is no pressure difference in the pressure block, and the passenger can get on and off comfortably.

[0019]

As is apparent from the above description, according to the present invention, the pressure difference between the inside and outside of the elevator shaft can be adjusted, and all elevators can be operated by one elevator.
