Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevator device, and in particular, for ascending and descending continuously in an intermediate seismic isolation building composed of a high-rise building installed via a seismic isolation device on a low-rise building installed on the foundation of the ground. It is related with the elevator apparatus which comprises a suitable hoistway.
[0002]
[Prior art]
In general, seismic isolation buildings are installed on the foundation via seismic isolation devices, but recently, considering the effective use of the underground and rational seismic isolation buildings, An intermediate seismic isolation building has been devised consisting of high-rise buildings installed via a seismic isolation device. The middle seismic isolation building penetrates from the high-rise part to the low-rise building, and the elevator hangs the lifting column from the bottom of the high-rise building under the high-rise part hoistway, and ascends or descends in the low-rise part hoistway. An elevator hoistway structure for a seismic isolation building is proposed in which the intermediate seismic isolation bearing floor is an intermediate floor and is fixed at the top and bottom.
[0003]
[Problems to be solved by the invention]
In order to avoid interference between the hoisting column suspended from the lower surface of the high-rise part and the wall of the hoistway of the low-rise building due to the relative displacement between the high-rise part and the low-rise part at the time of the earthquake, It is necessary to provide a clearance larger than the horizontal relative displacement amount between the wall of the hoistway of the lower layer part and the effective floor area of the lower layer part is reduced.
[0004]
Furthermore, there is a drawback that the swinging of the lower part of the lifting column due to the rocking motion of the high layer part is likely to occur.
[0005]
The object of the present invention relates to an elevator that moves up and down in an intermediate seismic isolation building having a seismic isolation support device in the middle part of the building, and the rationality of the building and the elevator even under relative displacement between the low and high floors during an earthquake. It is providing the elevator hoistway structure which can ensure safety | security of.
[0006]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention also arranges the lifting column in the high layer part, so that the upper end of the lifting support is fixed to the middle part of the high part and the lower part is fixed to the middle part of the low part, By supporting the middle part of the lifting column body with the column support beam, the horizontal shaking of the middle part of the lifting column body is constrained, and the relative displacement of the upper and lower layers during an earthquake is deformed. As a result, the elevator hoistway structure that can reduce the clearance between the lifting column and the building due to the horizontal displacement of the seismic isolation device was constructed.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
[0008]
In FIG. 1, a low-rise part 2 installed on the foundation 1 of the ground, and a high-rise part 4 is installed on the low-rise part 2 via a seismic isolation device 3 to constitute an intermediate seismic isolation building. . An elevator hoistway 5 is fixed to the upper part 4, and an elevator column 6 is fixed at an intermediate part thereof, and is suspended downward. A lower part of the elevator column 6 is connected to the hoistway 7 in the lower part 2. The horizontal direction is constrained via the constraining material 8, and the support column is deformed according to the horizontal relative displacement between the high layer portion and the low layer portion. In addition, in order to bring the deformation of the lifting column closer to the bending deformation and avoid the sudden bending deformation of the rail, it is preferable to provide two or more restraining members 8 in the vertical direction.
[0009]
Further, at the position where the length H2 of the lifting column body 6 inside the high layer part 4 and the length H1 of the lifting column body 6 inside the low layer part 2 are substantially equal , the upper part of the lifting column body 6 is connected to the hoistway 5. Further, by horizontally constraining the lower part of the lifting column body 6 to the hoistway 7, the clearance L <b> 2 between the lifting column body 6 and the hoistway wall 9 in the high layer part 4 and the hoistway wall 10 in the lower layer part 2 are clearance L1 may be of an earthquake, and L _0/2 of the horizontal relative displacement amount L ₀ between the high-rise portion 4 and the low rise portion 2 due to the shear deformation of the isolator to. In addition, it is preferable to provide support body support beams 22 having pin support portions 23 at both ends so as to keep the horizontal relative displacement amount of the lifting support body more uniform. The hoistway includes a floor door 11 at the entrance to the elevator on each floor of the building, a machine room 12 at the upper part of the hoistway, a car 13 in the hoistway, a counterweight 14, and guide rails 15 (not shown on the counterweight side). The guide rail 15 is supported by a hoistway 16 in the lower layer 2 below the lower end of the lifting column 6 in the lower layer 2. In the machine room 12, an elevator 19 is constituted by a hoisting machine 17, a rope 18 that is hooked to the hoisting machine 17 and is connected to a car 13 and a counterweight 14. A movable transfer plate 20 is provided between the floor surface of the floor slab 21 and the lifting column body 6 in accordance with the horizontal relative displacement between the lifting column body 6 and the lifting path 16.
[0010]
By constructing as described above, the clearance of the lower layer can be reduced, the floor area of the lower layer can be effectively used, and during the earthquake, the lifting column body is bent and deformed, but the lifting column body does not sway Can get on and off safely.
[0011]
【The invention's effect】
As described above, the present invention is a column support beam in which the lifting column connected to the hoistway of the high-rise part and the hoistway of the low-rise part is provided across the seismic isolation device between the high-rise part and the low-rise part. Because it is supported, the horizontal displacement of the lifting column body during an earthquake can be made to follow the horizontal displacement of the high and low layer parts. As a result, the clearance dimension between the lifting column body and the building can be reduced, This has the effect of avoiding a reduction in the floor area of seismic isolation buildings.
