In addition, continuous earthquake-resistant walls (for example, continuous earthquake-resistant walls 22A, 22C, and 22D to be described later) extending vertically and penetrating the equipment floor are provided.

According to this invention, the facility floor is provided directly above the multi-storey parking space. Therefore, by installing the lifting equipment for the multi-story parking lot on this equipment floor and installing equipment for the upper floors of the equipment floor, the equipment for the upper and lower floors of the equipment floor can be consolidated on the equipment floor, so the building height can be kept low.
In addition, since a continuous earthquake-resistant wall that is continuous in the vertical direction is installed to penetrate the equipment floor vertically, this continuous earthquake-resistant wall is not divided at the equipment floor located at the middle height of the building, and can be used from the lower floors of the building. It functions as a core material that continues to the upper floors, and can enhance the seismic performance of the building.
In addition, if a continuous seismic wall is installed in the lower part of the building where the seismic load acting on the building is large, the seismic performance of the building can be further improved.
Further, the building of the present invention is a composite building comprising a core portion and a peripheral portion provided around the lower portion of the core portion. Since it resists force (horizontal force), it is highly safe against earthquakes.

The building of the second invention is characterized in that at least part of the continuous earthquake-resistant wall (for example, a continuous earthquake-resistant wall 22C described later) is arranged to surround the multi-storey parking space in plan view.

According to this invention, at least a portion of the continuous earthquake-resistant wall is arranged to surround the multi-storey parking space in a plan view. Therefore, since most of the seismic load input to the building during an earthquake is borne by the continuous seismic wall, it is possible to reduce the deformation of structures such as pillars and beams of the multistory parking lot during an earthquake.

In the building according to the third aspect of the invention, at least one of lifting equipment for the multistory parking lot, equipment piping for upper floors of the equipment floor, a seismic isolation device, and a vibration damping device is installed on the equipment floor. characterized by

According to this embodiment, there are the following effects.
(1) The equipment floor 21 is provided directly above the multi-storey parking space 46 . Therefore, by providing lifting equipment for the multi-storey parking lot 47 on this equipment floor 21 and providing equipment piping for the upper floors of the equipment floor 21, the equipment for the upper and lower floors of the equipment floor 21 can be integrated on the equipment floor. Therefore, the building height can be kept low. Therefore, it is possible to reduce the influence of wind, sunshine, etc. that the building 1 has on the surrounding environment. In addition, since the equipment piping and lifting equipment for the multi-storey parking lot 47 are concentrated on the equipment floor 21, maintenance of equipment and equipment piping is facilitated while the building 1 is being used.
In addition, since the continuous earthquake-resistant walls 22A, 22C, and 22D that are continuous in the vertical direction are provided through the facility floor 21 in the vertical direction, the continuous earthquake-resistant walls 22A, 22C, and 22D are located at an intermediate height of the building 1. It functions as a core material continuous from the lower floor to the upper floor of the building 1 without being divided by the floor 21, and the earthquake resistance performance of the building 1 can be improved.
In addition, since the continuous seismic wall 22B is also installed in the lower part of the building where the seismic load acting on the building 1 increases, the seismic performance of the building 1 can be further enhanced.
In addition, the building 1 is a composite building including a core portion 20 and a peripheral portion 30 provided around the lower portion of the core portion 20. In the lower layer of the building 1, the core portion 20 and the peripheral portion 30 are integrated. As it resists seismic force (horizontal force), it is highly safe against earthquakes.

(2) A part of the continuous earthquake-resistant wall 22C is arranged to surround the multi-storey parking space 46 in plan view. Therefore, since most of the seismic load input to the building 1 during an earthquake is borne by the continuous seismic wall 22C, it is possible to reduce the deformation of structures such as columns and beams of the parking structure 47 during an earthquake. In addition, by arranging the parking structure 47 on the lower floor than the equipment floor 21, the vibration that the parking structure 47 exerts on the residential floor provided on the upper floor of the equipment floor 21 can be reduced.

(3) Since the outer wall 32 of the peripheral portion 30 has a wall-type structure, the pillar shape does not protrude into the building, so the design freedom of the interior of the building 1 can be increased. In addition, since wall pillars 33 are provided at predetermined intervals on the lowest floor of the peripheral portion 30, the load on the upper portion of the outer wall 32 can be collectively transmitted to the underground skeleton. In addition, in the peripheral part 30 of the wall type structure, since it is not always necessary to provide an outer wall directly below the upper outer wall 32, an arch-shaped opening 34 is provided to ensure a large width of the frontage for entering and exiting the building 1. - 特許庁
