The building according to the present invention divides a plane of a high-rise house into a plurality of blocks each having several blocks, and each block has an independent tube structure (hereinafter, referred to as a subtube). Are connected via a core part.

For example, the building shown in FIG. 1 has a basic structure in which two subtubes 1 and 1 are connected to each other via a core 2 in a plane-symmetric manner. In addition, the building shown in FIG. 2 has a basic structure in which two subtubes 1 and 1 are connected to each other via a core portion 2 so as to go wild. Further, the building shown in FIG. 3 has a basic structure in which three subtubes 1, 1, 1 located at each vertex of a triangle in plan view are connected to each other via a core portion 2 located at a midpoint of the triangle. Have been. Furthermore, the building shown in FIG.
The basic structure is such that four subtubes 1 to 1 located at respective corners of the rectangle in a plan view are connected to each other via a core 2 located at the midpoint of the rectangle.

FIG. 5 shows a more specific plan structure of a building having the basic structure shown in FIG. As shown in FIG. 5, the subtube 1 includes an outer peripheral portion 3 that bears seismic force acting on the subtube 1, a stud 4 that bears a vertical load acting on the subtube 1, and a floor slab 5. I have. The outer peripheral part 3 has a plurality of columns 6 standing up along the circumferential direction. In addition, for example, a super concrete pillar or the like is applied to the stud 4. Further, the subtube 1 having such a structure has a structure in which the upper structure and the foundation are independent from each other.

On the other hand, the core portion 2 for connecting the sub tubes 1 to 1 is made of a flexible floor / beam system which is pin-joined to each other. That is, both ends of the beams 7 constituting the core portion 2 are pin-joined to the columns 6, 6 of the outer peripheral portion 3 of the adjacent sub-tube 1, and a core portion floor (not shown) is formed on the upper surface of the beams. It has become.
The core section 2 is provided with a stud that bears a vertical load acting on the core section 2 together with the core section floor as necessary.

As described above, since the core portion 2 has a flexible structure, a structure in which displacement between the sub tubes 1 to 1 is not restricted to each other can be achieved. Further, by providing a damper for vibration suppression between the core portion 2 and the sub tubes 1 to 1 as necessary, the building can also have a vibration damping structure.

According to this embodiment, the following merits in architectural planning can be obtained. (1) The entire building is divided into a plurality of subtubes 1 to 1 having an independent tube structure in plan view, and these subtubes 1 to 1 are independently connected by a core portion 2. As shown in FIG. 4, various plan plans can be handled. (2) By such various floor plans, it is possible to make the arrangement of the house excellent in view, lighting, and privacy.
It is also possible to form an open core portion 2. (3) Furthermore, since the sub tubes 1 to 1 have an independent tube structure, the module and the shape can be changed for each sub tube 1. (4) In each of the sub-tubes 1 to 1, a wide space of each of the sub-tubes 1 to 1 can be secured by combining with the stud 4 and the floor slab 5 that bear the vertical load generated in each of the sub-tubes 1 to 1. it can.

Further, according to the present embodiment, the following merits in structural planning can be obtained. (1) Since the subtube 1 is constituted by the outer peripheral portion 3 that bears the seismic force acting on the subtube 1, the stud 4 and the floor slab 5 that bears the vertical load acting on the subtube 1, An independent optimal structure can be selected for each subtube 1. (2) Subtubes 1 to 1 for shaping (for example, rectangular in plan view)
By combining the above, it is possible to realize a building having an unshaped plane without twisting. (3) By changing the floor number of each subtube 1, a building having a setback without twisting can be realized. (4) By providing a damper in the core portion 2, seismic energy can be consumed by utilizing the interaction between the sub tubes 1 to 1, and the seismic energy input to each of the sub tubes 1 to 1 can be reduced. In particular, by intentionally changing the dynamic characteristics of each of the subtubes 1 to 1 (for example, changing the floor of each of the subtubes 1 to 1 and changing the natural period of each of the subtubes 1), the vibration control for the building is performed. The effect can be increased.

According to the present embodiment, the sub-tube 1
By unitizing ~ 1, it is possible to promote the unitization of buildings, thereby reducing on-site construction and shortening the construction period, and improving productivity by configuring the inside of the unit with the same member. Construction costs can be reduced. In addition, the foundation of the building is
