The building 100 also has auxiliary pillars 56 and pillars 66, and a clearance S is secured around the core portion 58 (elevator, stairs, etc.) provided on the left side of the building for absorbing displacement during an earthquake. doing.

  As shown in FIG. 2, the TP body 18 is received by the seismic isolation device upper beams 54 of (4) to (7) and [C] to [F]. Moreover, the core part 58 of a building is a street core, and only the pillar 52 of (1)-[D], (1)-[E], (3)-[D], (3)-[E] is a lower floor. Grate and connect to the base 50 for seismic isolation devices. As a result, the column 52, the seismic isolation device upper beam 54, and the seismic isolation device fixing base 50 are arranged in a balanced manner in the width direction and the depth direction, and a large force applied to the intermediate floor (the seismic isolation floor) is applied to the planar structure of the entire building. Can be reasonably communicated to the intermediate floor seismic isolation device 16.

  On the other hand, as shown in FIG. 3, the seismic wall 62 and the seismic isolation device lower beam 64 are provided between the cores (4) to (7)-[C] and [F] below the intermediate floor seismic isolation device 16.

Thus, the following effects can be obtained.

  The first effect is that the TP main body 18 is made to stand by providing a slight gap between the main body and the tower park column at normal times, and leans against the building main body 100 at the time of an earthquake, so that the structure does not become large. The cost for making it completely independent can be reduced. Further, by supporting the vertical load of the car lift unit 20 on the structure 22 on the intermediate floor seismic isolation device 16 via the TP body 18, the seismic isolation device provided below the car lift unit 20 can be minimized, or In the case of a completely suspended structure, only the gap can be formed, the dent (a) can be minimized, and the amount of ground cutting can be reduced. For this reason, the construction cost of a building can be reduced. Therefore, it is useful for construction of a high-rise building in an area where the building site is narrow and existing underground structures exist, and the total cost including demolition can be reduced.

  The second effect is that the cross section of the car lift section 20 is sufficient for a small area of about one vehicle. Therefore, as shown in FIG. A space usable range SP for providing a wall or the like can be secured, the rentable ratio of the building can be increased, and a structurally effective earthquake resistant wall or an opening earthquake resistant wall can be installed around the car lift portion 20. .

  The third effect is that the pillars and beams of the building main bodies 100 and 102, the foundation for fixing the seismic isolation device, the wall pillar, the seismic wall, or the opening seismic wall are reasonably balanced on the upper and lower floors of the intermediate seismic isolation device 16. Since it can arrange | position well, rationalization of a housing structure is attained and cost can be reduced.

In the seismic isolation structure of a middle floor of a building including a seismic device, the mechanical multi-story parking facility is provided on a lower side of the tower park main body having a garage shelf for housing a parked vehicle, and a lower side of the tower park main body. And a car lift part having a lifting shaft extending in the vertical direction for raising and lowering the parked vehicle from the vehicle entrance to the tower park body above, and isolating the load on the tower park body from the intermediate floor Received by the structure on the device.

  Therefore, the TP main unit normally has a slight gap between the main unit and the tower park pillar, and is self-supporting. In the event of an earthquake, the TP main unit behaves so as to lean against the building main unit, so that the structure does not need to be overwhelmed. The cost can be reduced. In addition, since the vertical load of the car lift can be supported by the structure on the intermediate floor seismic isolation device via the TP body, the seismic isolation device provided under the car lift can be minimized or suspended completely. If the structure is adopted, only the gap can be formed, and the amount of ground cutting can be reduced.

  In addition, the cross section of the car lift section needs only to secure a small area for about one vehicle, so that equipment rooms, living rooms, rooms for other uses, earthquake resistant walls, or open earthquake resistant walls are provided around the car lift section. Space can be secured, the rentable ratio of the building can be increased, and a structurally effective seismic wall or open seismic wall can be easily installed around the car lift part. From the above, it is possible to efficiently and rationally provide a building with a middle floor seismic isolation structure and a multilevel parking facility.

  As described above, the building with intermediate floor seismic isolation structure and multi-story parking facilities according to the present invention is useful for the construction of high-rise buildings in areas where the building site is narrow and the existing underground frame exists, It is suitable for reducing the total cost including the cost.
