It has. The ceiling of the core structure 22 is closed with a seismic wall. Here, the core structure 22 is constructed with higher rigidity than the external building 12. For this reason, the natural period of the core structure 22 is shorter than that of the external building 12. When an external force is applied to the building 10 due to an earthquake or the like, the core structure 22 and the external building 12 have different vibrations. Vibrate in mode.

The frame 21 supports the load of the vehicle stored in the parking facility 100, the pallet 131, and the machine room on the uppermost floor. Therefore, the total proof stress of the frame 21 and the frame 120 only needs to exceed the required proof strength against the load of the vehicle or the like applied to the parking facility 100, seismic force, or the like.

  Therefore, in this embodiment, the proof strength of the frame 120 alone is set to a level that does not satisfy the required proof strength against the load of the vehicle or the like applied to the parking facility 100 or seismic force, and the total proof strength of the frame 21 and the frame 120 is obtained. The structural design of the frame 21 and the frame 120 is performed so that the above-described required strength is exceeded. In particular, by setting the proof stress of the column members 123, 124, 125, and 126 lower than that when the frame 120 alone has the necessary proof strength, the cross-sectional areas of the column members 123, 124, 125, and 126 are reduced. It is set small.

Construction of the multistory parking lot 20 having the above-described configuration is performed in the following procedure.
First, the core structure 22 is constructed by a formwork method. In this step, the anchor bolt 24 is installed so as to penetrate the mold (not shown). Then, concrete is placed in the mold so that one end of the anchor bolt 24 is embedded. Thereby, the seismic walls 22A and 22B in which the anchor bolts 24 are placed are constructed.

  Next, the parking facility 100 is installed in the core structure 22. In this process, the beam member 23 and the column member 124 are fixed to the earthquake resistant walls 22A and 22B with the anchor bolt 24, and the parking facility 100 is assembled so that the load of the parking facility 100 is supported by the frame 21.

  As described above, the multi-story parking lot 20 according to the present embodiment includes the tower-type parking facility 100 including the elevator 110 that raises and lowers the vehicle, and the multistage storage shelves 130 that store the vehicle, and the parking facility 100. A core structure (concrete structure) 22 including seismic walls (concrete walls) 22 </ b> A and 22 </ b> B to be surrounded, and a plurality of beam members 23 fixed to the core structure 22 are provided.

  Here, the core structure 22 and the plurality of beam members 23 form a frame 21 that supports the load of the vehicle stored in the parking facility 100 and the storage shelf 130. As a result, the total proof stress of the frame 21 and the frame 120 only needs to exceed the required proof strength against the load of the vehicle or the seismic force applied to the parking facility 100, and the proof strength of the frame 120 alone satisfies the required proof strength. It doesn't have to be. Therefore, by setting the proof stress of the column members 123, 124, 125, and 126 lower than that when the frame 120 alone has the necessary proof strength, the cross-sectional areas of the column members 123, 124, 125, and 126 are reduced. Can be set small. Further, by directly fixing the beam member 23 and the earthquake-resistant wall 22 </ b> A so that there is no gap between them, the earthquake-resistant wall 22 </ b> A can be disposed on the center side of the core structure 22. The flat area of the multistory parking lot 20 can be reduced by the above. Moreover, since the proof stress of the frame 120 can be set low, the material cost of the steel material can be reduced.

  Further, here, in the multi-story parking lot 20 in which the frame 120 of the parking facility 100 is fixed to the core structure 22 via the beam member 23, vibration generated inside propagates to the outside via the core structure 22. And outside the multistory parking lot 20, there is an external building 12 that is a residential building. However, in the building 10 having the coupled vibration damping structure according to the present embodiment, the multistory parking garage 20 and the external building 12 are provided at an interval and are coupled by the vibration damping damper 16. Thereby, since the propagation of the vibration from the multi-story parking lot 20 to the external building 12 is suppressed by the vibration damper 16, the comfortability of the external building 12 can be ensured.

  In particular, in the present embodiment, the damping damper 16 is a hydraulic damper (oil damper). However, the hydraulic damper is superior in vibration absorption performance compared to other damping dampers such as steel dampers. Therefore, in this embodiment, the propagation of vibration from the multi-story parking lot 20 to the external building 12 can be effectively suppressed, so that the vibration of the multi-story parking lot 20 does not affect the habitability of the external building 12. can do.

  Moreover, in the construction method of the multistory parking lot 20 according to the present embodiment, the anchor bolts 24 are placed on the earthquake-resistant wall 22 </ b> A at intervals in the height direction, and the multi-stage beam constituting the frame 21 together with the core structure 22. The material 23 is fixed to the earthquake resistant wall 22 </ b> A by the anchor bolt 24, and the parking facility 100 is constructed so that the load is supported by the frame 21. Thereby, the parking facility 100 can be supported by the frame 21 during the construction of the parking facility 100. Therefore, the parking facility 100 can be constructed safely.

  In addition, the above-mentioned embodiment is for making an understanding of this invention easy, and does not limit this invention. It goes without saying that the present invention can be changed and improved without departing from the gist thereof, and that the present invention includes equivalents thereof. For example, in the above-described embodiment, the multilevel parking garage 20 is fixed to a pair of parallel earthquake-resistant walls 22A with a pair of parallel beam members 23, and both ends of the beam member 122 between them are paired with another pair of earthquake-resistant materials. Although it was set as the structure fixed to the wall 22B, you may make it the structure etc. which provide the beam material orthogonal to the beam materials 23 and 122 further, and fix this beam material to the earthquake-resistant wall 22B.
