Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a high-rise building equipped with a vibration isolation device.

[Prior art and problems to be solved by the invention] At present, the development of buildings with vibration-isolated structures is active, but in general, a vibration-isolating device is interposed between the foundation and the superstructure to absorb the seismic force of an earthquake. It is devised so that it does not enter into the superstructure of objects.

However, in high-rise buildings, the load on the upper structure is large, making it difficult to implement this method because the vibration isolation device becomes large. Furthermore, since the upper part of a high-rise building has a large sway, it is desirable to have a structure that accommodates this.

This invention has been developed to address the above-mentioned problems.

[Means for solving problems]

This invention attempts to absorb vibrations that occur during an earthquake in several stages by arranging vibration isolation devices at multiple levels for each required floor in the height direction of a high-rise building.

〔Example〕

The drawing shows an outline of the invention, in which an upper building 2 is installed on a foundation 1, and insulation is provided between the foundation 1 and the upper building 2 and at multiple levels for each required floor such as the 5th to 20th floors. A shaking device 3 is arranged.

As the vibration isolation device 3, a laminated rubber bearing, a sliding bearing, an elastoplastic damper, an oil damper, a viscous damper, etc. are used. Furthermore, on the floor where the upper vibration isolation device is installed, the horizontal atrium is space A, and the vibration isolation device 3 is placed between the pillars 4. Furthermore, the floor where the vibration isolation device 3 is installed can have upper and lower beams intersecting each other, and the vibration isolation device can be placed at the intersection of the upper and lower beams. Furthermore, a space B can be provided in the atrium in the vertical direction as well.

[Function and effect of the invention]

In the conventionally researched and developed seismic isolation structures, a vibration isolation device is installed between the foundation and the superstructure, and the short-period intense vibrations that occur in the foundation during an earthquake are reduced to long-period, slow vibrations in the superstructure. However, in this invention, by providing vibration isolators in several stages, vibrations are sequentially absorbed in response to the magnitude of shake as the building progresses to the upper floors, so a relatively small vibration isolator is required, and it is suitable for high-rise buildings. It can also be applied to objects. Furthermore, if a vibration isolator is installed between the pillars of the atrium, maintenance and management of the vibration isolator will be easier.
