DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a seismic isolation complex according to the present invention will be described below with reference to FIGS. FIG. 1 is an overall schematic elevation view of a building according to the present embodiment, and FIG. 2 is an overall perspective view thereof. Reference numeral 1 in the figure is, for example, 200 m × 150 m =
It is a single- or low-rise base building that is provided on a large-scale site of about 30,000 m ^{2 and} has a size that covers almost the entire area. The base building 1 is provided in a seismic isolation pit 2 that is dug down on the entire site and supported by a column 3 and a seismic isolation device 4 installed above the pillar 3. The roof of the base building 1 is flat, and a plurality of low-rise or middle-rise upper buildings 5 and 6 are constructed therewith using the seismic isolation artificial ground, and there are sufficient green spaces 7 and open spaces 8 around it. Is secured.

As a use of the base building 1, a logistics center and a warehouse in which various materials are accumulated and function as a delivery base in normal times are preferable, and a base for evacuation and rescue utilizing its functions even in the event of a disaster. It can be made to function as. The upper buildings 5 and 6 provided on the base building 1 are appropriately used for commercial facilities such as stores, public facilities such as government offices and hospitals, low-rise houses, middle-high-rise offices and apartment houses.

The above-mentioned seismic isolation device 4 is provided in the seismic isolation pit 2 and most of it is used as a parking lot in normal times, but it can be used as an evacuation site in the event of a disaster. For this purpose, it is preferable to provide the seismic isolation device 4 with a fireproof coating. In addition, a part of the seismic isolation pit 2 includes various facilities for supplying energy such as electric power, water, and heat source to the whole seismic isolation complex, specifically, substation facilities, private power generation facilities, district heating and cooling facilities, Water, sewage, and rainwater storage tanks, sewage treatment facilities, septic tanks, sewage tanks, etc. are also provided, as are telecommunications-related central facilities such as telephones, networks, and broadcasting. Are also planned to be functionally sustainable.

The type of the above-mentioned seismic isolation device 4 is not particularly limited, but as shown in FIG. 3 (a), a laminated rubber 14 of a high damping laminated rubber bearing type having excellent energy absorption efficiency at the time of small and medium-sized earthquakes, and (b) As shown in the figure, an elastic slide bearing type that can realize a long period in the case of a large earthquake by interposing the slide plates 16 and 17 between the ordinary laminated rubber 15 and the building can be suitably adopted. Also (a),
It is also preferable to use the combination of (b). In particular, the combination of the high-damping laminated rubber bearing and the elastic sliding bearing enables seismic isolation of a complex building composed of low-rise and middle-rise buildings, and it is most preferable to do so. In addition, if the seismic isolation device 4 is used in combination with an oil damper, a more damping effect can be obtained, which is suitable for a case where it is expected that the entire building will be twisted.

[0013] Since the above seismic isolation complex is provided over the entire large-scale site, it is itself a single block,
Or if it is larger, it can itself function as a small city. Further, since the entire structure is seismically isolated and supported by the seismic isolation device 4, even in the event of a large earthquake, the entire safety can be ensured and major damage can be avoided. In particular, since the upper buildings 5, 6 are constructed on the base building 1, which is an artificial base, the seismic resistance of the upper buildings 5, 6 is lower than when the upper buildings 5, 6 are constructed directly on the natural ground. The structure required for securing can be reduced.

The base building 1, which also serves as an artificial ground,
Its normal use is as a distribution center and warehouse where various goods are accumulated and used as a delivery base. Therefore, in the event of a disaster, this distribution center can be effectively used as it is as a collection and delivery base for rescue supplies. However, it is also suitable for stockpiling a large amount of various supplies necessary during a disaster from normal times.

Further, the seismic isolation pit 2 which is normally used as a parking lot can be used as an evacuation center capable of accommodating a large number of victims immediately in the event of a disaster. The resulting power and water can be used. Of course, green spaces 7 and open spaces 8 on the artificial ground can also be used as shelters.

In the event that access to this building from the land is interrupted in the event of a disaster, access from the air is possible using the open space 8 secured on the artificial ground as a heliport. Further, when this building is provided in a seaside area, it is possible to access by sea by providing a ship berth 20.

[0017]

As described above, according to the present invention, the entire large-scale building is seismically isolated and supported by the seismic isolation device, so that even in the event of a large earthquake, the overall safety is ensured. Damage can be avoided, and the seismic performance of the upper building provided on the base building as the seismic isolated artificial ground can be reduced.

If the ordinary use of the base building also serving as the seismic isolation artificial ground is a distribution center and a warehouse, it can be effectively used as it is as a base for accumulation and delivery of relief supplies in the event of a disaster, and It is also possible to stockpile a large amount of various supplies necessary during a disaster from normal times.

Further, the seismic isolation pit as a space for installing the seismic isolation device can be used as an evacuation center, and the energy-related facilities such as electric power, water, and heat source provided to the entire seismic isolation complex can be maintained in the event of a disaster. Can be used as it is in evacuation life.

Further, if a seismic isolation device using a high-damping laminated rubber bearing, an elastic sliding bearing, or a combination thereof is used, the entire large-scale and multipurpose building as in the present invention can be used. The period can be sufficiently lengthened and an excellent energy absorbing effect can be obtained. If an oil damper is used in combination, a more excellent damping effect can be obtained.
