Description

  The present invention relates to a building in which a seismic wall arranged in a cylindrical shape continuous to upper and lower floors is provided in a central portion of a building plane, and the seismic resistance is improved by the seismic wall.

  Conventionally, as shown in FIG. 4, this type of building has the function of an inner peripheral column added to the earthquake resistant wall 1, while a plurality of columns 2 are arranged in an annular position on the outer periphery of the building. There was what formed the frame structure part 20 over the surrounding earthquake-resistant wall and the outer peripheral side pillar (for example, refer patent documents 1-4).

JP 2002-121922 A (FIGS. 1 to 5) JP 2002-121923 A (FIGS. 1 to 5) JP 2002-121924 A (FIGS. 1 to 5) Japanese Patent Laid-Open No. 2002-121925 (FIGS. 1 to 5)

According to the above-mentioned conventional building, the span between the seismic wall part and the pillar standing on the outer periphery of the building tends to be large, and as a result, it is necessary to secure a large beam structure and floor slab thickness of the ramen structure part. There is.
Therefore, when the floor height is constant, the indoor height is lowered and the comfortability is lowered. On the other hand, when the indoor height is constant, the floor height is likely to be high and within a predetermined building height. However, there is a problem that it is easy to make a frame design lacking rationality.

  Accordingly, an object of the present invention is to solve the above problems and provide a building having a highly rational frame.

  A first characteristic configuration of the present invention is a building in which a seismic wall arranged in a cylindrical shape continuous to upper and lower floors is provided in a central portion on a building plane, on the outer peripheral side from the seismic wall on the building plane. A ramen structure part in which a plurality of columns are arranged in a ring shape and a plurality of layers is provided, and a large beam is provided in a state of protruding from the inner peripheral side column of the ramen structure part over the earthquake-resistant wall.

  According to the first characteristic configuration of the present invention, a ramen structure part in which a plurality of pillars are arranged annularly and in a plurality of layers is provided on the outer peripheral side of the earthquake-resistant wall on a building plane, and the inner part of the ramen structure part is provided. Since the large beam protrudes from the circumferential column over the earthquake-resistant wall, the span of each of the inner and outer columns in the ramen structure is smaller than before, and the beam formation and floor slab in the ramen structure It is possible to reduce the thickness. As a result, if the floor height is kept constant, the interior height can be kept high to improve the comfort, or if the interior height is kept constant, the floor height can be lowered and the specified building height It becomes possible to make a building with a high rationality of the frame, such as increasing the number of floors in the area.

  The second characteristic configuration of the present invention is that the earthquake-resistant wall is supported by the large beam.

  According to the second characteristic configuration of the present invention, in addition to achieving the above-described operation and effect of the first characteristic configuration of the present invention, the earthquake-resistant wall is supported by the ramen structure portion via the large beam. Therefore, the seismic wall can be supported by the foundation structure of the ramen structure. As a result, it is possible to design without the need for a dedicated foundation under the seismic wall, and the plan of the lower floor is implemented as a ramen structure without the seismic wall. It becomes possible to make it. As an example, it can be mentioned that the upper floor is designed as a residence, while the lower floor is designed for a tenant building, so that the building usage plan can be performed very easily.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the parts indicated by the same reference numerals as those in the conventional example indicate the same or corresponding parts.

[First Embodiment]
1 and 2 show a high-rise house B which is a first embodiment of the building of the present invention, in which an atrium space A1 is formed in the center, and a residential space A2 is formed around it. Yes. In the present embodiment, a description will be given by taking as an example a reinforced concrete high-rise house B constructed in a substantially similar frame over all floors.

The planar structure of the building will be described. A cylindrical earthquake-resistant wall 1 is provided in a state surrounding the atrium space A1, and a plurality of pillars 2 are provided on the outer peripheral side of the annular earthquake-resistant wall 1 (double in this embodiment). A ramen structure portion 3 arranged at a position is provided.
The ramen structure 3 includes a large beam 4 laid over each column 2 and a slab 5 provided over each large beam 4.
Further, a large beam 6 is provided in a protruding state across the earthquake-resistant wall 1 on the annular inner peripheral column 2a.
And each pillar 2 and the earthquake-resistant wall 1 are each supported by the foundation.
A slab 7 is also provided in a range surrounded by the large beams 4, the large beams 6, and the earthquake-resistant wall 1.

  According to the building of the present embodiment, it is possible to reduce the beam formation and the slab thickness by the short-span structure ramen structure portion 3 while improving the earthquake resistance performance as a building by the earthquake-resistant wall 1. If the floor height is constant, the interior height is secured to improve the comfort, or if the floor height is constant, the floor height can be lowered and within the specified building height. It is possible to make the building with a high rationality of the frame, such as increasing the number of floors.

[Second Embodiment]
FIG. 3 shows a second embodiment of the building of the present invention, and the description of the parts common to the previous embodiment is omitted, and different configurations are mainly described.
The building employs a frame provided with a series of indoor spaces A3 having an atrium space A1 similar to that of the first embodiment on the upper floor, and a series of indoor spaces A3 having no atrium space A1 on the lower floor.

  That is, the earthquake-resistant wall 1 on the upper floor is supported by each of the large beams 6. The lower beam 8 is constructed over the pillars 2 below the atrium space A1 to form a lower ramen structure 9.

Therefore, since the earthquake-resistant wall 1 is supported by the lower-level frame structure portion 9 via the large beams 6 and 8, the foundation of the earthquake-resistant wall 1 alone is not provided.
On the other hand, the lower floor ramen structure 9 is supported by the foundation below the pillar 2.

  According to the building of this embodiment, while improving the seismic performance as a building by the earthquake-resistant wall 1, the beam formation and the slab thickness are reduced by the ramen structure portion 3 having a short span configuration on the upper floor. As in the previous embodiment, the building can be a highly rational building. Furthermore, since the seismic wall 1 is supported by the girder 6, the seismic wall 1 can be supported by the foundation structure of the ramen structure 9, and a dedicated foundation is not provided below the seismic wall 1. The design which may be sufficient is enabled. In other words, it is possible to improve the freedom of building plan planning, for example, by executing the floor plan of the lower floor as a ramen structure without the earthquake-resistant wall 1, and it is possible to plan the use of the building very easily. It becomes.
