Abstract

PROBLEM TO BE SOLVED: To avoid lowering of floor area of an intermediate base isolated building by fixing the upper end part of an elevating base to an intermediate part of a high storied part, fixing the lower part of the elevating base to an intermediate part of a low storied part, and supporting an intermediate part of the elevating base by a base supporting beam. SOLUTION: A high storied part 4 is installed on a low storied part 2, arranged on the foundation 1 of the ground, through a base isolating device 3 to construct an intermediate base isolated building. An elevating support body 6 is fixed to the high storied part 4 at an intermediate part of an elevator shaft 5 and hung downward. A lower part of the elevating support body 6 is horizontally constrained to the elevator shaft 7 in the low storied part 2 through a constraining material 8 so as to be constituted in such a way that deformation is generated to the support body 6 according to horizontal displacement of the high storied part 4 and low storied part 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator system and, more particularly, to an intermediate seismic isolation building comprising a high-rise building installed on a low-rise building installed on a ground foundation through a seismic isolation device. The present invention relates to an elevator apparatus constituting a hoistway suitable for continuously moving up and down.

[0002]

2. Description of the Related Art In general, a seismic isolation building is installed on a foundation through a seismic isolation device. An intermediate seismic isolation building consisting of a high-rise building installed via a seismic isolation device on a multi-story building has been devised. The elevator penetrates from the high-rise building to the low-rise building through the middle seismic isolation building, and the elevator suspends the hoisting column from the lower surface of the high-rise building under the high-rise hoistway, and moves up or down the low-rise hoistway. There has been proposed an elevator hoistway structure for a base-isolated building in which the intermediate base-isolated bearing floor is an intermediate floor and fixed at upper and lower portions.

[0003]

The above-mentioned prior art is based on the problem that a relative displacement between a high-rise portion and a low-rise portion during an earthquake causes a lifting column suspended from the lower surface of the high-rise portion and a wall of a hoistway of a low-rise building. In order to avoid interference, it is necessary to provide a clearance larger than the horizontal relative displacement between the lifting column and the wall of the hoistway in the low-rise section, which has the disadvantage that the effective floor area of the low-rise section is reduced.

[0004] Furthermore, there is a disadvantage that whirling of the lower portion of the lifting column is easily caused by the rocking motion of the high-rise portion.

An 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 of the building, and is capable of rationalizing the building even under relative displacement between a low-rise section and a high-rise section during an earthquake. An object of the present invention is to provide an elevator hoistway structure that can ensure the safety and safety of the elevator.

[0006]

According to the present invention, in order to achieve the above-mentioned object, an elevating column is also arranged on a high-rise part. By fixing to the middle part of the low-rise part and supporting the middle part of the elevating support body with the support beam, the horizontal shaking of the middle part of the elevating support body is restrained, and the high and low parts during the earthquake are restrained. By absorbing the relative displacement by the deformation of the hoisting column, an elevator hoistway structure can be constructed in which the clearance between the hoisting column and the building due to the horizontal displacement of the seismic isolation device can be reduced.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG.
2 will be described with reference to FIG.

In FIG. 1, a low-rise section 2 is installed on a foundation 1 of the ground, and a high-rise section 4 is installed on the low-rise section 2 via a seismic isolation device 3 to constitute an intermediate seismic isolation building. doing. In the high-rise section 4, there is a hoistway 5 for elevators,
The lifting column 6 is fixed and hung downward, and the lower portion of the lifting column 6 is attached to the lifting path 7 in the low-rise section 2 by a restraining member 8.
The horizontal direction is constrained through the support, and the support is deformed in accordance with the horizontal relative displacement between the high-rise section and the low-rise section. In addition, in order to make the deformation of the elevating support body closer to the bending deformation and to avoid the sharp bending deformation of the rail, it is preferable to provide the restraining member 8 at two or more places in the vertical direction.

The length H of the lifting column 6 in the high-rise section 4
2 and the height H1 of the lifting column in the low-rise section 2 are substantially equal to each other.
L2 between the elevator and the hoistway wall 9 in the high-rise part 4 and the clearance L1 between the hoistway and the hoistway wall 10 in the low-rise part 2
Can be set to Lo / 2 of the horizontal relative displacement Lo between the high-rise section 4 and the low-rise section 2 due to the shear deformation of the seismic isolation device during an earthquake. Further, it is preferable to provide a column support beam 22 having pin support portions 23 at both ends so as to keep the horizontal relative displacement of the lifting column more uniform. In the hoistway, the floor door 11 at the entrance to the elevator on each floor of the building, and the machine room 1 above the hoistway
2, the cage 13 in the hoistway, the counterweight 14, these guide rails 15 (not shown on the counterweight side), and these guide rails On the hoistway 16 inside. In the machine room 12, the hoisting machine 17, the hoisting machine 17,
An elevator 19 is constituted by a rope 18 connected to the counterweight 3 and the weight 14. In addition, the transfer plate 20 that can move in accordance with the relative displacement between the lifting column 6 and the hoistway 16.
Is provided between the floor surface of the floor slab 21 and the lifting column 6.

With the above construction, the clearance of the low-rise part can be reduced, and the floor area of the low-rise part can be effectively used. You can get on and off safely without turning.

[0011]

As described above, according to the present invention, the horizontal relative displacement of the high and low sections during an earthquake is the horizontal deformation of the lower column and the upper column, and the vertical relative displacement is the lower column guide mechanism. Since the clearance between the support and the building only needs to be provided according to the horizontal deformation of the support, the clearance dimension can be reduced, and the floor area of the intermediate seismic isolation building can be avoided. Has an effect.
