[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-73589 Summary of the Invention [Problem to be solved by the invention]

[0004] In a building with a beam-supported rigid frame structure, when constructing a large space such as an office, the rigid frame columns installed on the exterior walls alone may not be sufficient structurally. However, if additional rigid frame columns are installed indoors, the rigid frame columns may affect the living space. [Means for solving the problem]

[0005] (1) A building that solves the above problem is a building that includes a first exterior wall, a second exterior wall facing the first exterior wall, a third exterior wall connecting the first exterior wall and the second exterior wall, and a plurality of first sleeve walls extending from the third exterior wall toward the interior of a room, and a first column serving as a rigid-frame column is disposed in at least one of the plurality of first sleeve walls. With this configuration, the building can suitably dispose the first column as a rigid-frame column inside the room.

[0006] (2) The building of (1) above further includes a ceiling portion, in which a plurality of first beams are arranged parallel to the first and second exterior walls, a first end of at least one of the first beams being supported by a first support pillar, and a second end of at least one of the first beams being supported by a second support pillar arranged in a position opposite the third exterior wall inside the room. This configuration improves the strength of the framework of the building.

[0007] (3) In the building of (1) or (2) above, the building comprises a first room surrounded by the first exterior wall, the second exterior wall, and the third exterior wall, wherein a plurality of third columns are arranged as rigid-frame columns in a first portion of the first exterior wall facing the first room, a plurality of fourth columns are arranged as rigid-frame columns in a second portion of the second exterior wall facing the first room, and a plurality of fifth columns are arranged as rigid-frame columns in a third portion of the third exterior wall facing the first room, wherein the first columns, the third columns, the fourth columns, and the fifth columns are each arranged with their strong axes oriented in either a first orientation along the first exterior wall or a second orientation along the third exterior wall, and the ratio of the number of the first columns, the third columns, the fourth columns, and the fifth columns arranged in the second orientation to the number of columns arranged in the first orientation is 0.8 or more and 1.2 or less. According to this configuration, the strength of the building can be improved by the first, third, fourth and fifth pillars serving as rigid frame pillars.

[0008] (4) In the building of (3) above, the orientation of the first pillar in the first sleeve wall and the orientation of the third pillar in the first exterior wall are the first orientation, a first opening is provided in the first exterior wall, and the third pillar is arranged in a part of the first exterior wall different from the first opening. According to this configuration, the building can improve the indoor environment by providing the first opening in the first exterior wall.

[0009] (5) In the building of any one of (1) to (4) above, each of the plurality of first sleeve walls has a first dimension from the third outer wall to a first end face of the first sleeve wall, the first dimension being 0.5 m or more and 2 m or less. With this configuration, the building can arrange first sleeve walls of a suitable length indoors.

[0010] (6) In the building of any one of (2) to (4) above, each of the first beams has a second dimension from the first end to the second end, and the second dimension is 5 m or more and 7.5 m or less. With this configuration, the building can have an interior space of a suitable size.

[0011] (7) In the building of any one of (1) to (6) above, the first end faces of the plurality of first sleeve walls are patterned differently from the inner faces of at least one of the first outer wall, the second outer wall, and the third outer wall. This configuration improves the design of the interior of the building.

[0012] (8) In the building of any one of (1) to (7) above, a plurality of first rooms are provided, each surrounded by the third exterior wall and two first sleeve walls. With this configuration, users can utilize the plurality of first rooms as spaces for various purposes.

[0013] (9) In the building of (8) above, the depth length of at least one of the plurality of first rooms is different from the depth lengths of the other first rooms of the plurality of first rooms. With this configuration, users can use each of the first rooms with different depth lengths according to their purpose.

[0014] (10) In the building of (8) or (9) above, the ceiling height of the plurality of first rooms is lower than the ceiling height of the portion of the building that is different from the plurality of first rooms. With this configuration, the building can distinguish the first rooms from the portion that is different from the first rooms.

[0015] (11) In the building of any one of (2) to (4) and (6) above, the first beams are connected to one another by first connecting members. This configuration improves the strength of the framework of the building.

[0016] (12) In the building of any one of (2) to (4) and (6) above, at least one second beam extending parallel to the plurality of first beams and a first girder extending perpendicular to the plurality of first beams are arranged in the ceiling portion, and the second beam is arranged between two of the plurality of first beams and connected to the first girder. With this configuration, the strength of the framework of the building can be improved.

The first dimension A1 is 0.5 m or more and 2 m or less. With this configuration, the building 1 can arrange first sleeve walls 15 of an appropriate length indoors.

[0076] (6) Each of the first beams 28 has a second dimension A2 from the first end 28A to the second end 28B. The second dimension A2 is equal to or greater than 5 m and equal to or less than 7.5 m. This configuration allows the building 1 to have an interior space of an appropriate size.

[0077] (7) The first end faces 15A of the plurality of first sleeve walls 15 are patterned differently from the inner surfaces of at least one of the first exterior wall 12, the second exterior wall 13, and the third exterior wall 14. This configuration allows the building 1 to have an improved interior design.

[0078] (8) The building 1 has a plurality of first rooms 7 surrounded by a third exterior wall 14 and two first sleeve walls 15. With this configuration, users can utilize the plurality of first rooms 7 as spaces for various purposes.

[0079] (9) The depth length of at least one of the plurality of first chambers 7 is different from the depth lengths of the other first chambers 7 of the plurality of first chambers 7. With this configuration, the user can utilize the first chambers 7, each with a different depth length, according to the purpose of use.

[0080] (10) The ceiling height of the plurality of first rooms 7 is lower than the ceiling height of the portions of the building 1 that are different from the plurality of first rooms 7. With this configuration, the building 1 can distinguish between the first rooms 7 and the portions that are different from the first rooms 7 within the building.

[0081] (11) The first beams 28 are connected to one another by the first connecting members 32. This configuration allows the building 1 to have improved strength of its framework.

[0082] (12) At least one second beam 29 extending parallel to the plurality of first beams 28 and a first girder 34 extending perpendicular to the plurality of first beams 28 are arranged in the ceiling portion 4. The second beam 29 is arranged between two of the plurality of first beams 28. The second beam 29 is connected to the first girder 34. This configuration can improve the strength of the building 1 and the framework.

[0083] (13) The building 1 includes a first inner wall 17 facing the third outer wall 14, and a plurality of second sleeve walls 16 extending from the first inner wall 17 toward the third outer wall 14. A second support column 31 is disposed on at least one of the plurality of second sleeve walls 16.
