JPH1081467A - Machine room arranging structure of hydraulic elevator for base isolation building - Google Patents

Abstract

PROBLEM TO BE SOLVED: To take a living room sound quieting measure against vibration and a noise of a machine room, and also effectively use a base isolation pit space by arranging the machine room under an under surface of a base isolation building on the outside of the base isolation building as well as on the outside of a closed hoistway of an elevator. SOLUTION: A base isolation pit space 9 of a recessed part shape is formed in a footing 1 in the relationship opposed to a base isolation building 4. A base isolation support 3 is arranged on a floor surface of a base isolation pit floor 2, and the base isolation building 4 is supported by a base isolation building under surface 5. A hoistway 6 of a hydraulic elevator in the base isolation building 4 has a pit part 7 projecting in the base isolation pit space 9 from the base isolation building under surface 5. A machine room 8 of the hydraulic elevator is installed on a pit part side surface 15 of the hoistway 6 as well as on the base isolation building under surface 5 by fixation or suspension. Since the machine room 8 is not placed in the base isolation building 4, laying of an oil sending pipe 10 to the hydraulic elevator becomes shortest, and propagation of vibration and a noise of the machine room 8 into the base isolation building 4 can be reduced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine room layout structure of a hydraulic elevator installed in a base-isolated building.

[0002]

2. Description of the Related Art Seismic isolation buildings have been introduced as a means of disaster prevention to reduce urban disasters caused by earthquakes. A hydraulic elevator has been installed in this seismic isolation building.

A seismic isolation building has been introduced as a means of disaster prevention to reduce urban disasters caused by earthquakes. FIG. 5 shows a conventional machine room arrangement when a hydraulic elevator is installed in this seismic isolation building. The problem to be solved in the conventional arrangement of the machine room will be described.

[0004] A seismic isolation building 4 installed via a seismic isolation element 3 on a seismic isolation pit floor 2 of a foundation 1 may be installed at a top position 13 of the building due to the layout and arrangement of the building. However, it is generally installed at a position 14 below the building.

[0005]

In a base-isolated building, there is little basement space like a non-base-isolated building, so there is little effective space for arranging common equipment such as a hydraulic machine room. There are many. On the other hand, measures to reduce noise in the living room against vibration noise in the machine room of the hydraulic elevator are important in residential buildings and the like, but in seismic isolation buildings, the measures are often difficult due to layout restrictions.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and is intended for a seismically isolated building in which a countermeasure against vibration noise in a machine room of a hydraulic elevator is provided and a seismic isolation pit space is effectively utilized. It is intended to provide a machine room layout structure for hydraulic elevators.

[0007]

According to the present invention, a hoistway of a hydraulic elevator is installed in a seismic isolation building, and a pit portion of the hoistway protrudes into a seismic isolation pit space below the seismic isolation building. In a machine equipped with a hydraulic elevator machine room for supplying hydraulic pressure to an elevator, the hydraulic elevator machine room is located outside the seismic isolation building and outside the elevator up / down closed circuit and below the bottom surface of the seismic isolation building. Provided is a machine room arrangement structure of a hydraulic elevator for a base-isolated building.

Preferably, the machine room is attached to a side surface of the pit portion of the hoistway and is attached to a lower surface of the seismic isolation building.

Preferably, the machine room is arranged apart from the lower surface of the base-isolated building.

[0010] Preferably, the machine room is arranged outside a wall of the seismic isolation pit space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

In FIG. 1, a base-isolated building 4 is supported on a foundation 1 by a base-isolating element 3. The base 1 is formed with a seismic isolation pit space 9 which is concave and faces the seismic isolation building. The depth H of this space is usually 2 to 2.5 m, but it is not necessary to stick to this depth. A seismic isolation bearing 3 is installed on the floor of the seismic isolation pit floor, and a seismic isolation building 4 is supported by a lower surface 5 of the seismic isolation building. In such a base-isolated building structure,
The hoistway 6 of the hydraulic elevator in the seismic isolation building 4 has a pit portion 7 protruding into the seismic isolation pit space 9 from the lower surface 5 of the seismic isolation building so that the elevator can service the lowest floor. Here, the machine room 8 of the hydraulic elevator is arranged on the pit side surface 15 of the hoistway and on the lower surface 5 of the seismic isolation building by attachment or suspension.

With this arrangement, there is no need to place a machine room in the seismic isolation building.
Laying is shortest, and the vibration noise of the machine room can be reduced in the seismic isolation building.

FIG. 2 is a view showing another embodiment, in which the machine room 8 is disposed in the foundation 1 outside the seismic isolation pit wall 13, and the hydraulic pressure of the hydraulic elevator is U-shaped from the machine room 8. It is supplied to the pit 7 of the hoistway of the hydraulic elevator via the flexible oil pipe. This oil pipe is thus supported by the strut 11.

The feature of this arrangement structure is that since the machine room is buried in the foundation 1, the noise insulation characteristics of the machine room noise are good.

FIG. 3 shows another embodiment in which the machine room 8 is directly installed on the seismic isolation pit floor 2.
By doing so, the cost of installing the machine room can be reduced.

[0017]

The arrangement structure of the machine room of the elevator for a base-isolated building described above is more effective than the conventional structure in which a machine room is installed in a base-isolated building. Propagation of room vibration noise into the building is reduced,
This has the effect of reducing noise in the building.
