As in the above-mentioned Patent Document 1, if a configuration in which a high-rigidity main building encloses the entire outer periphery of a low-rigidity sub-building is adopted, the size of the entire building becomes large in plan view, and it is applicable to a narrow land. In addition, the boundary wall between the sub-building and the main building enclosing the entire outer periphery of the sub-building becomes very wide, which complicates the structure. Furthermore, there is also the problem that natural lighting from the surroundings cannot be obtained in the sub-building section.
In view of this situation, the main object of the present invention is to provide a building comprising a main building portion and a sub-building portion that is joined to the side of the main building portion and has lower rigidity than the main building portion.

Along the outward direction, the low-rigidity secondary building section can be firmly supported by the high-rigidity main building section. As a result, seismic forces acting on the secondary building from multiple directions can be favorably borne by the main building, which has a higher rigidity than the secondary building, so that a wide internal space can be secured in the secondary building. .
Further, in a plan view, the main building section is configured in a shape that opens the outer periphery of at least one of the sub building sections, and the main building section exists outside the outer periphery of at least one of the sub building sections. Since it is not necessary, it is possible to secure natural lighting to the sub-building section through the open outer perimeter, and to minimize the installation area of the building. Furthermore, since the boundary wall between the main building section and the sub-building section is limited to at least two outer peripheries excluding the open perimeter of the sub-building section, the structure can be simplified.

Furthermore, even though the sub-building section is steel-framed, the seismic force acting on the sub-building section is mainly borne by the main building section, so a wider internal space can be secured in the sub-building section.

A third characteristic configuration of the present invention is that the main building section is configured in an L shape along two adjacent outer peripheries of the sub building section in a plan view.

According to this configuration, in a plan view, the main building section and the sub building section are arranged such that the two adjacent outer peripheries of the sub building section are aligned with the inner corner of the L-shaped main building section. can do. As a result, the two outer peripheries of the sub-building section other than the outer perimeter along the main building section are left open, so that natural lighting to the sub-building section can be sufficiently ensured. A configuration that can be applied more simply and rationally even in a narrow space can be achieved.

A fourth characteristic configuration of the present invention is that the main building section is configured as a school building, and the sub-building section is configured as a gymnasium.

According to this configuration, in plan view, the main building section configured as a school building is configured in a shape along at least two adjacent outer peripheries of the sub-building section configured as a gymnasium. In the outer periphery, it is possible to secure access and views to and from the school building. In addition, since the seismic force acting on the gymnasium, which is the sub-building portion, is favorably borne by the school building, which has a higher rigidity than the gymnasium, a large internal space can be secured in the gymnasium.

A fifth characteristic configuration of the present invention is that the pillars of the main building section and the sub building section and the foundations supporting the same are used in the parting wall section between the main building section and the sub building section. be.

According to this configuration, the parting wall between the main building section and the sub-building section uses the pillars of the main building section and the sub-building section and the foundations that support them, thereby realizing a simpler and more rational configuration. can be realized.

A sixth characteristic configuration of the present invention is that the main building section is provided with a quake-resistant wall, and the quake-resistant wall is omitted in an area other than the parting wall section between the sub-building section and the main building section. .

According to this configuration, the seismic force acting on the secondary building is mainly borne by the main building. Seismic walls can be omitted in areas other than the parting wall. Therefore, it is possible to secure a wider internal space in the sub-building part, and furthermore, by omitting the seismic wall along the open outer periphery, it is possible to secure better natural lighting from the surroundings. can be done.

As shown in FIG. 1, a building (hereinafter referred to as "main building") 50 according to the present embodiment includes a main building section 1 and a sub-building section 2 joined to the side thereof. While adopting a configuration in which the main building section 1 bears the seismic force of the entire building 50 including the building section 2, allowing natural lighting to the sub building section 2, it can be easily and rationally applied even in a narrow area. The following describes the details of the configuration.
In the present application, the building section indicates a frame section having a column interval of one span or more in the short side direction and the long side direction in a plan view.

The main building section 1 is a building section made of reinforced concrete with high rigidity, and is mainly configured as a school building. On the other hand, the secondary building section 2 is a steel frame structure with lower rigidity than the main building section 1, and is mainly configured as a gymnasium.
In the plan view shown in FIG. 2, the sub building section 2 is configured in a rectangular shape, and the main building section 1 has two adjacent outer peripheries 2a on the side of the main building section. , 2b.
That is, the inner outer perimeters 1a and 1b, which are two adjacent outer perimeters on the inner side of the L-shape in the main building section 1, are the two adjacent outer perimeters in the rectangular sub-building section 2, which are the main building section side outer perimeters. It will be in the state which overlaps with the surroundings 2a and 2b. Further, open side outer peripheries 2c and 2d, which are outer peripheries other than the main building section side outer peripheries 2a and 2b in the rectangular sub building section 2, are in an open state where the main building section 1 does not exist outside. becomes.

By adopting such a configuration, along the out-of-plane direction of each of the two main building portion side outer peripheries 2a and 2b in the sub building portion 2, the low rigidity sub building portion 2 and the high rigidity main building portion 1 strongly supported by The seismic forces acting on the secondary building section 2 from multiple directions are favorably borne by the main building section 1 having higher rigidity than the secondary building section 2 . Therefore, the sub-building part 2 can be suitably used as a steel-framed gymnasium that secures a wide internal space.
In a plan view shown in FIG. 2, the main building section 1 is configured such that the open side outer peripheries 2c and 2d of the sub building section 2 are open. , 2d does not exist outside the main building portion 1 . Therefore, natural daylighting to the sub-building section 2 is ensured through the open side outer peripheries 2c and 2d, and the installation area of the building 50 can be made small.
Furthermore, the boundary wall portion 6 between the main building portion 1 and the sub building portion 2 is restricted to the main building portion side outer peripheries 2a and 2b excluding the open side outer peripheries 2c and 2d of the sub building portion 2 which are opened. is simplified. In addition, at the boundary wall portion 6 between the main building portion 1 and the sub-building portion 2 corresponding to the two main building portion side outer peripheries 2a and 2b of the sub-building portion 2, the sub-building portion 2 configured as a gymnasium and the school building Access and view between the main building part 1 configured as

As shown in FIG. 3, at the boundary wall 6 between the main building section 1 and the sub-building section 2, there are columns 11 of the main building section 1 and foundations 21 that support them, columns 12 of the sub-building section 2 and their The base 22 for supporting the is also used, and a simpler and more rational configuration is realized. In this embodiment, the pillars 11 and 12 and the foundations 21 and 22 that support them are used in the entire area of the boundary wall 6 between the main building 1 and the sub-building 2. The pillars 11 and 12 and the foundations 21 and 22 may not be shared between the main building section 1 and the sub-building section 2 in part or all of the wall section 6 .

In particular, at least one seismic wall 5 is arranged in the area of the main building section 1 where the seismic force is transmitted from the sub-building section 2 perpendicularly to the side outer perimeters 2a, 2b of the main building section. On the other hand, in the secondary building section 2, the distance between columns is set wide to form a large space without columns, but the seismic force acting on the secondary building section 2 is mainly borne by the main building section 1. Therefore, the above earthquake-resistant wall is omitted in the area other than the boundary wall 6 with the main building 1, that is, in the area of the outer wall along the outer peripheries 2c and 2d on the open side. As a result, a wider interior space is secured in the sub-building section 2 configured as a gymnasium. It is possible to ensure better natural lighting from the surroundings in the open side outer peripheries 2c and 2d. Although FIG. 2 shows an example of the arrangement of the earthquake-resistant wall 5 in the building 50, the arrangement of the earthquake-resistant wall 5 can be changed as appropriate. For example, in order to further improve the accessibility and viewability between the sub building section 2 and the main building section 1, it is arranged along the parting wall section 6 between the main building section 1 and the sub building section 2. It is also possible to minimize or eliminate the earthquake-resistant wall 5 which
