Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevator apparatus.
[0002]
[Prior art]
There are buildings with seismic isolation devices in the middle. In such a building, the upper layer and the lower layer of the seismic isolation device move differently in the horizontal direction. Therefore, when the elevator apparatus is provided through the upper floor and the lower floor, there is a risk that the guide rail of the elevator apparatus may be deformed or damaged in the layer portion where the seismic isolation device is provided.
[0003]
[Problems to be solved by the present invention]
In order to solve such a problem, it is possible to adopt a method in which separate elevator devices are provided on the lower floor and the upper floor of the floor where the seismic isolation device is installed. However, it is difficult to adopt such a configuration in the case of general low-rise and middle-rise buildings due to the trouble of changing elevators, regardless of whether it is a super high-rise building.
[0004]
The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide an elevator apparatus that can be easily adopted in low-rise and middle-rise buildings where seismic isolation devices are installed.
[0005]
[Means for Solving the Problems]
To achieve the above object, the elevator apparatus of the present invention, in a building which is interposed isolator in the middle of the hierarchy, established the elevator guide rails through the seismic isolation floor, base isolation the hierarchy of the device, attach the top end to the upper floor of the seismic isolation floor, established the support posts fitted with bottom under floor seismic isolation floor, holds the elevator guide rails by the support struts, the support struts, the The elevator apparatus is characterized in that upper and lower ends are attached to the upper and lower floors by universal joints .
[0006]
[Embodiments of the present invention]
Hereinafter, embodiments of an elevator apparatus according to the present invention will be described in detail with reference to the drawings.
[0007]
<I> Structure of the building.
The object to which the elevator apparatus of the present invention is adopted is a building in which one building is divided in the middle as shown in FIG. 1 and the seismic isolation device 1 is interposed in the middle hierarchy. As the seismic isolation device 1, conventionally known devices such as a device using laminated rubber, a device using Teflon having a small friction coefficient, and the like can be adopted. In any seismic isolation device 1, relative horizontal movement occurs above and below the level where the seismic isolation device 1 is installed during an earthquake.
[0008]
<B> Guide rail.
A guide rail 2 for guiding the movement of the elevator car 3 is installed in the vertical direction on the elevator shaft as in the prior art. As this guide rail 2, a conventional general guide rail can be used as it is.
[0009]
<C> Restraint band.
The restraint band 4 may be attached in a state of surrounding the guide rail 2. By restraining from the surroundings by the restraining band 4, the distance between the guide rails 2 can be accurately maintained even during deformation. As a result, the elevator car 3 can be prevented from being removed. The restraint band 4 is preferably attached at a position above and below a support position on a support column, which will be described later.
[0010]
<D> Fixed bracket.
The elevator shaft, to project the bracket 5 toward the interior space from the walls surrounding the seismic isolation floor of the upper and lower layers. The guide rail 2 is fixed from the periphery by the bracket 5. The bracket 5 firmly holds the guide rail 2 from the surroundings using a simple steel material whose dimensions and position do not change. By thus securing the rail in seismic isolation floor of the upper and lower floor from the surroundings, the deformation of the rail can be distributed across multiple floors, the upper and lower stories of the deviation those gentle deformation of the rail and may occur during an earthquake Can be. Therefore, the stress of the rail can be kept within the elastic range, and the elevator car can be moved smoothly even during deformation.
[0011]
<E> Support column.
A support column 6 is installed at the level of the seismic isolation device. The support struts 6 are attached to the upper end seismic isolation floor upstairs, for example at a position corresponding to the ceiling of the seismic isolation floor. The lower end of the support posts 6, seismic isolation floor lower level, for example, attached to a position corresponding to a seismic isolation floor floor. A horizontal arm projects from the support column 6 toward the elevator shaft. And the front-end | tip of a horizontal arm is fixed to the guide rail 2 of an elevator. Then, the guide rail 2 can be held by the support column 6. Further, when the support column 6 is tilted at the time of an earthquake, the guide rail 2 that has been in the vertical state until then can be tilted in an orderly manner substantially along the tilt of the support column 6.
[0012]
<F> Universal joint.
The support column 6 is configured by attaching upper and lower ends thereof to the upper and lower floors by a universal joint 61. That is, the upper end and the lower end of the support column 6 are not fixed integrally to the upper and lower slabs, but can be displaced in the entire circumferential direction. Therefore, even if the upper and lower floors are displaced relatively in any direction during an earthquake, the support column 6 can be tilted freely and will not be damaged.
[0013]
<G> Elevator elevator 3 is raised and lowered.
Next, the operation will be described. During an earthquake, the upper and lower floors move relatively horizontally through the level of the seismic isolation device 1. Then, since the upper and lower ends of the support column 6 are attached by the universal joint 61, the upper end of the column 6 follows the movement of the upper floor, and the lower end follows the movement of the lower floor, and the middle is continuously deformed. As a result, the guide rail 2 supported by the support column 6 is also continuously deformed in a substantially similar state. Therefore, even in the level where the seismic isolation device 1 is installed, the guide rail 2 is not deformed at a steep angle in part, and can maintain a smooth continuous shape. Elevator car 3 was being moved in the hierarchy seismic isolation device 1 during an earthquake To that end, even be inclined, without lifting is prevented, the seismic isolation device 1 by the operation of such known sensors Smoothly arrives at and stops at the hierarchy level or above and below it.
[0014]
[Effect of the present invention]
As described above, the elevator apparatus of the present invention smoothly deforms without the deformation of the guide rail 2 being concentrated on a part, so that the passenger can safely move without disturbing the smooth movement of the elevator car 3 even during an earthquake. You can evacuate.
