DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator hoistway, and more particularly, to an intermediate seismic isolation building consisting of a high-rise building installed on a low-rise building installed on a foundation via a seismic isolation device. The present invention relates to an elevator hoistway for an intermediate seismic isolation building that is suitable for ascending and descending continuously.

[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 hoistway structure is suspended from the lower part of the high-rise building under the high-rise hoistway so that the elevator goes up and down the high-rise part through the middle seismic isolation building from the low-rise part to the hoistway in the low-rise part. Hoistway structure for intermediate seismic isolation buildings is proposed (Japanese Patent Publication No. 5-4)
No. 9595).

[0003]

According to the above prior art, assuming that the relative horizontal swing amount between the low-rise section and the high-rise section at the time of the earthquake is Lo, the lifting column suspended from the high-rise section to the low-rise section and the low-rise section In order to make the clearance taken to avoid interference with the hoistway above Lo, it is necessary to make the hoistway cross-sectional area of the low-rise part wider than that of the high-rise part, and there is a disadvantage that the effective floor area of the low-rise part becomes small. In addition, since the elevating column in the low-rise section is suspended from the high-rise building, the length of the elevating column, that is, the height of the low-level section is limited due to the restriction of the strength of the joint with the high-rise section.

An object of the present invention relates to a hoistway of 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. An object of the present invention is to provide an elevator hoistway for an intermediate seismic isolation building that can ensure the rationality of the building and the safety of the elevator.

[0005]

According to the present invention, in order to achieve the above object, a support is provided between a low-rise section and a high-rise section,
An elevator hoistway for an intermediate seismic isolation building capable of absorbing the relative displacement at the time of the earthquake by the horizontal deformation of the support and reducing the clearance between the support and the building due to the horizontal displacement of the seismic isolation device.

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

In FIG. 1, an intermediate seismic isolation building 5 comprising a low-rise part 2 and a high-rise part 4 via a seismic isolation device 3 on a foundation 1, and an elevator 6 in this building 5 is moved by a rope 7 through a machine room A known hoisting machine 9 in 8 runs in hoistways 10 and 11 in low and high sections.

A rail 12 for guiding the elevator 6
The lower part 12 ′ is in the hoistway 10 of the low-rise part 2,
2 ″ is a lower support 13 fixed to an intermediate portion of the lower story 2
The upper part 12 '''is attached to the hoistway 11 of the high-rise part via brackets 14, 15, and 16, respectively.

In addition, the hoistway 11 of the high-rise section 4 is provided with the lower support 1 by the horizontal relative displacement Lo of the seismic isolation device 3 during an earthquake or the like.
3 is provided with a column guide mechanism 17 for generating horizontal deformation such as shearing deformation and bending deformation.

The support body guide mechanism 17 is provided on the hoistway 11.
The horizontal displacement of the upper portion 18 of the lower support 13 is restrained by the side wall of the lower support 13 to cause horizontal deformation of the lower support 13 by the horizontal relative displacement Lo. Vertical displacement due to change, 2) Vertical subsidence due to shear deformation during earthquake, and 3) Vertical fluctuation due to vertical movement of earthquake Is provided between the tip 19 of the upper part 18 of the lower support 13 and the side wall of the hoistway 11, and the upper part 18 of the lower support 13 is provided within the vertical clearance. Consists of a mechanism that slides while being restrained in the horizontal direction.

The lower support 13 is not deformed in the horizontal direction due to the horizontal relative displacement Lo of the seismic isolation device 3 so that the lower support 13 does not interfere with the hoistways 10, 11.
The cross section of the hoistway is widened in accordance with the amount of deformation of No. 3, and clearances L1 and L2 are provided between the hoistways 10 'and 11' and the lower support 13 respectively.

The clearance reduces the effective floor area of the building. To minimize this, the lengths H1 and H2 of the lower support 13 in the low-rise section 2 and the high-rise section 4 are substantially reduced. When the lower pillars 13 are arranged so as to be equal to each other, the necessary clearances of the hoistways 10 'and 11' are L1 = L2 = Lo / 2, and a decrease in the effective floor area can be minimized.

The upper portion 12 "" attached to the lower support 13 in accordance with the above-mentioned relative vertical displacement is, for example, a spring clip (not shown) which permits vertical sliding at a portion where the bracket 16 is engaged. Hold it down and attach it to the bracket.

In this embodiment, depending on the height of the high-rise part,
Alternatively, if the length of the upper part 18 of the lower support part 13 of the lower support body guide mechanism is lengthened, the rail 12 ′ ″ may be omitted, and in this case, the vertical relative displacement of the seismic isolation device 3 may be reduced. Rails are no longer affected. Further, in the present embodiment, there is a form in which the lower portion 12 'is not provided depending on the height of the low layer portion 2.

FIG. 2 shows that the lower support 13 is provided with a plurality of supports 2.
The struts are connected by a horizontal frame 21 to stabilize the horizontal deformation of each strut. Further, in order to stabilize the deformation of the support, the support is made of a circular material, and in order to prevent inadvertent lateral vibration, the support is provided between the longitudinal center of the lower support 13 and the hoistway. It is preferable to provide a well-known damper or the like that absorbs the roll vibration of the body.

There may be a case where two to four elevators are provided in one hoistway, but the columns 20 may be arranged according to the arrangement of the elevators.

In this deformed state, the intermediate portion 12 "supported by the lower support body portion 13 also undergoes the same deformation. The lower support column is so formed that the stress generated in each part of the structure due to this deformation is allowed. Determine the length of the body part 13 (H1, H2, etc.)
There is a need.

The upper part 12 "" attached to the upper part of the hoistway of the high-rise part 4 with the above-mentioned vertical relative displacement has a bracket 16, for example, a spring clip (not shown) structure which allows vertical sliding. It is good to adopt.

FIG. 3 shows an embodiment in which the lower support 13 is fixed on the low-rise section 2.
The length of the lower support body 13 and the hoistway 11 ″, 1
The clearance from 1 "" needs to be at least Lo, but the cross section of the hoistway changes only in the high-rise section 4 and can be selected according to the layout form such as the partition of the building.

The clearance between the lower support 13 and the hoistway does not need to be constant, and the clearance L3 of the hoistway 11 "" is Lo according to the deformation of the lower support 13.
Can be smaller. This clearance is applied to the lower support 13
Can be changed according to the modified form of the hoistway 1 in FIG.
It is also possible for the 0 'and 11' parts.

FIG. 4 shows a column support mechanism 22 having a mechanism similar to the column guide mechanism 17 described with reference to FIG.
The lower strut 13 and the upper strut 13 ′ are attached to the lower strut 13 and the upper strut 13 ′ by the horizontal relative displacement between the low strut 2 and the high strut 4 under the horizontal deformation shown in FIG. 5. Prop body 1
3 'is composed of a plurality of columns 20', 20 ", respectively, and rails are supported on cross beams 21 ', 21" connecting the columns.

The vertical displacement of the low-rise portion 2 and the high-rise portion 4 is caused by the displacement between the upper end of the support 20 'of the lower support 13 and the lower end of the support 20 "of the upper support 13'. It is absorbed by the clearance K 'provided.

The lower strut body portion 13 in the low-rise portion 2 and the high-rise portion 4,
By making the lengths H1 and H2 of the upper support 13 'substantially equal, the clearances L1 and L2 between the support and the hoistways 10' and 11 'become approximately 1/2 of Lo as in the configuration of FIG. A reduction in the effective floor area of the building can be minimized.

In this embodiment, since the lower support guide mechanism 22 is located in the space between the low-rise section and the high-rise section, it is easy to inspect the support body guide mechanism section.

FIG. 6 shows another embodiment of the column guide mechanism 22. The column 2 forming the upper column portion 13 'is shown.
A fitting guide 23 for fitting a clearance K ″ in the vertical direction to the top of the support 20 ′ is attached to the tip of the support 0 ′ to form a support guide mechanism 22 ′.

FIG. 7 shows an embodiment in which the lower support 13 is disposed only in the lower section 2.
The clearance between the hoistway in the low-rise part 2 and the lower support 13 is determined by the horizontal relative displacement L of the seismic isolation device 3.
However, as in the embodiment of FIG. 3, depending on the horizontal deformation state of the lower support 13, as shown in FIG.
By changing o, L4, and L5 depending on the position, a decrease in the effective floor area of the low-rise section 2 can be prevented.

In the rail mounting structure, the low-rise part 2
The middle part 12 ″ in FIG.
Similarly, in the embodiment shown in FIGS. 4 and 7, the rail bracket portion of the high-rise portion has a sliding function, or the rail 24 of the low-rise portion 2 has the same function as the clearance of the column guide mechanism.
A rail joint 26 having a clearance and a sliding mechanism in the longitudinal direction of the rail may be provided at a rail joint between the rail and the rail 25 of the high-rise section 4.

[0028] The distance between the well-known floor door attached to the building side to enter and exit the elevator and the well-known car door attached to the elevator car is required to be kept at a certain distance or less for safety in getting on and off. The floor door follows the car door in response to the deformation of the column, and the floor door is attached to the lower column and the upper column to ensure the safety of getting on and off when the column is deformed. It is better to attach.

As another embodiment of the present invention, an elevator 6 attached to one end of a rope 7 and a counterweight (not shown) attached to the other end during an earthquake both have a lower support 13 and an upper support. At the position of the body part 13 ',
Since the inertial force due to the weight of the elevator 6 and the counterweight acts on the lower support 13 and the upper support 13 ', the lower support 13 and the upper support 13' are configured to withstand these inertial forces. Since it is necessary, the lower support 13 and the upper support 13 'are positioned so that the elevator 6 and the counterweight are not located at positions facing the lower support 13 and the upper support 13'. It is desirable to change the installation position. The lower support body 13 and the upper support 13 are arranged in such a manner that the lower support 13 and the upper support 13 'are installed together with the elevator 6 so that the weights are not located together.
3 'may be a structure that can withstand a load with a large inertial force, either of the weights balanced with the elevator 6, so that the structure can be rationalized.

[0030]

As described above, according to the present invention, the horizontal relative displacement of the high and low layers during an earthquake is caused by the horizontal deformation of the column composed of the lower column and the upper column, and Since the displacement can be absorbed by the support guide mechanism, the clearance between the support and the building only needs to be provided according to the horizontal deformation of the support, so that the clearance dimension can be reduced, and the floor area of the intermediate seismic isolation building Has the effect of preventing the decrease of
