Summary of the Invention

Problems to be Solved by the Invention

[0004] In the prior art, an exterior panel is merely used as an interior finish, and the structure of the inner wall on which the exterior panel is used is the same as that of other inner walls. By the way, sound insulation or heat insulation may be required indoors. From this point of view, a new building is proposed.

Means for Solving the Problems

[0005] (1) A building that solves the above problems is a building having a building body, wherein the building body includes an outer wall and a continuous inner wall portion that is orthogonal and connected to the outer wall portion so as to be continuous with a part of the outer wall, and the continuous inner wall portion is provided such that at least a part of the continuous inner wall portion is located indoors and has the same internal structure as the outer wall portion.

[0006] According to this configuration, a sound insulation wall or a heat insulation wall can be provided indoors. Further, since the continuous inner wall portion has the same structure as the outer wall portion, the continuous inner wall portion can be efficiently formed in the construction of the building.

[0007] (2) In the building according to (1) above, the building body further includes window sashes, and each window sash includes a window sash outer frame and a window sash window movably attached to the window sash outer frame. The exterior finish of the outer wall portion is provided on the outer wall portion and the continuous inner wall portion so as to be continuous from the outer wall portion to the continuous inner wall portion, and at least a part of the window sash outer frame is embedded in the exterior finish.

[0008] According to this configuration, it is possible to prevent the window sash outer frame from being visible from inside or outside the room, or to make the window sash outer frame less conspicuous. As a result, when the window sash window is closed, the ratio of the window glass to the opening of the building can be increased. Further, when the window sash window is opened, since the window sash outer frame is difficult to see, the opening of the building can be made to look beautiful.

[0009] (3) In the building according to (1) or (2) above, the building body has four corners, and each of the four corners of the building body has a core structure. The four core structures include a first outer wall portion as the outer wall portion, a second outer wall portion orthogonal to the first outer wall portion, a connecting wall connected to be continuous with the second outer wall portion, a first column provided at a portion where the first outer wall portion and the second outer wall portion are connected to each other, a second column provided at a portion where the second outer wall portion and the connecting wall are connected to each other, a third column provided at a position separated from the first column by a predetermined distance in the first outer wall portion, and a fourth column provided at a position separated from the second column by a predetermined distance in the connecting wall. In at least one of the four core structures, the connecting wall is configured as the continuous inner wall portion.

[0010] According to this configuration, the building is supported by the four core structures. In this way, since the columns can be concentrated at the four corners of the building, the number of columns provided inside the building can be reduced. As a result, the degree of freedom in the layout of the interior of the building can be increased. And since the connecting wall is configured as the continuous inner wall portion, the degree of freedom in the layout of the interior of the building can be increased as compared with the case where all of the connecting walls are configured as the outer wall portion.

[0011] (4) In the building according to (3) above, the building main body has a first room indoors, and the first room is configured to be surrounded by the first outer wall portion, the second outer wall portion, and the connection wall in the core structure, and the connection wall is configured as the continuous inner wall portion. According to this configuration, the first room can be used as a room with high sound insulation or heat insulation. The first room can be used, for example, as a bathroom, a laundry room, a music room, a staircase room, or a study room.

[0012] (5) In the building according to (3) or (4) above, the building main body has an outdoor enclosed space surrounded by the outer wall portion outdoors, and the outdoor enclosed space is configured to be surrounded by the first outer wall portion, the second outer wall portion, and the connection wall in the core structure, and the connection wall is configured as a part of the outer wall.

[0013] According to this configuration, an outdoor enclosed space surrounded by three walls can be provided outdoors by the first outer wall portion, the second outer wall portion, and the connection wall. The outdoor enclosed space can be used, for example, as a windbreak or a shaded relaxation space connected to a veranda.

[0014] (6) In the building according to any one of (3) to (5) above, the first column, the second column, the third column, and the fourth column are connected by a first connecting member so as to be rectangular in plan view. According to this configuration, the seismic resistance of the core structure can be improved.

[0015] (7) In the building according to (3) above, the core structure is connected to another core structure by two second connecting members. According to this configuration, the seismic resistance of the building can be improved.

[0016] (8) In the building according to (7) above, the core structure is connected to another core structure by two of the second connecting members, and is further connected to yet another core structure by two of the second connecting members. Of the four second connecting members, the two second connecting members located on the indoor side are connected to each other by a reinforcing member. According to this configuration, the seismic resistance of the building can be improved.

Effect of the Invention

[0017] According to the technology of the present disclosure, a building having a sound insulation wall or a heat insulation wall can be provided.

Examples of the outer wall portion 11 are the first outer wall portion 21 and the second outer wall portion 22 described later.

[0025] When the connection wall 23 described later is disposed indoors, it is classified as the inner wall 9. When the connection wall 23 is disposed outdoors, it is classified as the outer wall 10. When the first floor portion of the connection wall 23 is disposed indoors and the second floor portion is disposed outdoors, the connection wall 23 is classified into different wall types for the first floor portion and the second floor portion.

[0026] A specific example of Building 1 will be described below. As shown in FIGS. 1 and 2, the building main body 2 has four corner portions 3. In the building main body 2, a core structure 13 is provided at each of the four corner portions 3 of the building main body 2. The four core structures 13 each include the same structure. The four core structures 13 include at least a first outer wall portion 21 and a second outer wall portion 22 orthogonal to the first outer wall portion 21, as will be described later. Each of the four core structures 13 is arranged such that a corner portion 13A formed by the first outer wall portion 21 and the second outer wall portion 22 is located at the corner portion 3 of the building main body 2.

[0027] The building main body 2 further has a first room 5 inside the first floor 2A. The first room 5 is provided inside the core structure 13, as will be described later. The building main body 2 may have a second room 7 other than the first room 5. The second room 7 is configured such that, for example, the four core structures 13 are located around the second room 7.

[0028] The building main body 2 further includes a veranda 4 on the second floor 2B. The veranda 4 is arranged so as to surround the indoor floor of the second floor 2B of the building main body 2. The veranda 4 is partitioned into four regions 4A.

[0029] The building main body 2 further includes a sash 15. The sash 15 includes a sash outer frame 16 and a sash window 17 movably attached to the sash outer frame 16. The sash 15 partitions the interior and the exterior. The sash 15 is arranged between two core structures 13. The sash 15 is arranged so as to connect the two core structures 13 in the horizontal direction.

[0030] [Core Structure] The core structure 13 includes a first outer wall portion 21, a second outer wall portion 22 orthogonal to the first outer wall portion 21, a connecting wall 23 connected so as to be continuous with the second outer wall portion 22, a first column 31, a second column 32, a third column 33, and a fourth column 34.

[0031] The second outer wall portion 22 is connected to one end of the first outer wall portion 21. The connecting wall 23 is arranged parallel to the first outer wall portion 21 and is connected so as to be orthogonal to the second outer wall portion 22. The connecting wall 23 may be connected to the end of the second outer wall portion 22 on the side opposite to the first outer wall portion 21. The connecting wall 23 may be connected to an intermediate portion other than both ends of the second outer wall portion 22.

[0032] The first outer wall portion 21, the second outer wall portion 22, and the connecting wall 23 have the same internal structure. Also, the first outer wall portion 21, the second outer wall portion 22, and the connecting wall 23 have the same internal structure from the first floor 2A to the second floor 2B. The internal structure of the connecting wall 23 includes a column 30, a heat insulating material 35, an inner base material 37, and an outer base material 36.

[0033] The outer structures of the first outer wall portion 21, the second outer wall portion 22, and the connecting wall 23 may be the same or different from the first floor 2A to the second floor 2B.

[0034] The core structure 13 in the upper right of FIG. 9 will be described as an example. In the core structure 13 in the upper right of FIG. 9, the first floor portion of the first outer wall portion 21 is provided with an exterior material 38 on one surface and an interior material 39 on the other surface. The second floor portion of the first outer wall portion 21 is provided with exterior materials 38 on both surfaces. The second outer wall portion 22 is configured in the same manner as the first outer wall portion 21.

[0035] In the core structure 13 in the upper right of FIG. 9, the first floor portion of the connecting wall 23 is provided with interior materials 39 on both surfaces. The second floor portion of the connecting wall 23 has two portions. The two portions of the second floor portion of the connecting wall 23 have different outer structures. Specifically, in the second floor portion of the connecting wall 23, the portion disposed on the veranda 4 is provided with exterior materials 38 on both surfaces. In the portion of the second floor portion of the connecting wall 23 that partitions the interior and the exterior, an exterior material 38 is provided on one surface and an interior material 39 is provided on the other surface.

[0036] With reference to FIGS. 3 and 4, the arrangement of the first column 31 to the fourth column 34 in the core structure 13 will be described. The first column 31 is provided at a portion where the first outer wall portion 21 and the second outer wall portion 22 are connected to each other. The second column 32 is provided at a portion where the second outer wall portion 22 and the connecting wall 23 are connected to each other. The third column 33 is provided in the first outer wall portion 21 at a location separated from the first column 31 by a predetermined distance. The fourth column 34 is provided in the connecting wall 23 at a location separated from the second column 32 by a predetermined distance.

[0037] As shown in FIG. 5, the first column 31, the second column 32, the third column 33, and the fourth column 34 are arranged so as to be located at the vertices of a rectangle in plan view. Then, the first column 31, the second column 32, the third column 33, and the fourth column 34 are connected by a first connecting member 41 so as to form a rectangle in plan view. The first connecting member 41 is, for example, a beam.

[0038] [Connection structure between core structures] As shown in FIG. 5, the core structure 13 is connected to another core structure 13 by two second connecting members 42. Specifically, the core structure 13 is connected to another core structure 13 by two second connecting members 42, and is further connected to another core structure 13 by two second connecting members 42. The second connecting member 42 connects the column 30 of one core structure 13 and the column 30 of the other core structure 13 to each other. The second connecting member 42 is, for example, a beam.

[0039] As shown in FIG. 6, among the four second connecting members 42 connected to the core structure 13 at the corner 3, the two second connecting members 42 located on the indoor side may be connected to each other by a reinforcing member 43. Thereby, the second floor can be reinforced. Also, the sway of the core structure 13 can be reduced against external vibrations.

[0040] [Internal space of the core structure] The core structure 13 extends from the first floor 2A to the second floor 2B of the building 1. The core structure 13 has an internal space SA surrounded by a first outer wall portion 21, a second outer wall portion 22, and a connecting wall 23. In the core structure 13, the internal space SA is divided into a first floor portion and a second floor portion. The core structure 13 has an opening 24 for people to enter the internal space SA in each of the first floor portion and the second floor portion. The core structure 13 may have a sleeve wall 25 for installing fittings at the opening 24.

[0041] As shown in FIG. 7, for all of the four core structures 13, the internal space SA of the first floor portion of the core structure 13 is arranged indoors. In this case, the connecting wall 23 of the core structure 13 is configured as a continuous inner wall portion 12. The internal space SA of the first floor portion of the core structure 13 is configured as a room according to the use.

[0042] In the present embodiment, the first room 5 in the core structure 13 is configured to be surrounded by the first outer wall portion 21, the second outer wall portion 22, and the connecting wall 23 configured as a continuous inner wall portion 12. The first room 5 is configured as, for example, a bathroom, a laundry room, a music room, a staircase room, or a study room.

[0043] As shown in FIG. 8, for two of the four core structures 13, the internal space SA of the second floor portion of the core structure 13 is arranged indoors. For the other two of the four core structures 13, the internal space SA of the second floor portion of the core structure 13 is arranged outdoors and constitutes an outdoor enclosed space SB surrounded by the outer wall portion 11. The outdoor enclosed space SB is surrounded by the first outer wall portion 21, the second outer wall portion 22, and the connecting wall 23 in the core structure 13. The connecting wall 23 is configured as a part of the outer wall 10. The outdoor enclosed space SB is configured as, for example, a windbreak or a shaded relaxation space connected to the veranda 4. The outdoor enclosed space SB may be configured as a region for drying laundry. The outdoor enclosed space SB may be configured as a storage portion for outdoor furniture.

[0044] In the core structure 13, the internal space SA may be connected from the first floor part to the second floor part. Such a space may be configured as a space for arranging an elevator for transporting objects, for example.

[0045] As described above, in the present embodiment, at least one connection wall 23 among the four core structures 13 is configured as the continuous inner wall portion 12. Specifically, in the four core structures 13, the first floor part of the connection walls 23 is configured as the continuous inner wall portion 12. In the four core structures 13, the second floor part of the connection walls 23 is configured as a part of the outer wall 10. The second floor part of the connection wall 23 partitions the veranda 4.

[0046] [Structure of the outer wall part and exterior continuous structure] Referring to FIG. 9, the structure of the outer wall part 11 will be described. FIG. 9 is an enlarged view of the upper right corner part of FIG. 1. Note that, in FIG. 9, the description of the television 50 shown in FIG. 1 is omitted. The outer wall part 11 includes two or more columns 30, a heat insulating material 35 disposed between the two columns 30, an outer base material 36, an inner base material 37, and an exterior material 38. The exterior material 38 is fixed to the outer base material 36 via the body edge 38A.

[0047] As shown in FIG. 9, in the part of the building body 2 shown in FIG. 9, the continuous inner wall portion 12 has the same internal structure as the outer wall part 11 and has the same outer structure as the outer wall part 11. The exterior 18 of the outer wall part 11 is provided on the outer wall part 11 and the continuous inner wall portion 12 so as to be continuous from the outer wall part 11 to the continuous inner wall portion 12.

[0048] [Arrangement of the sash outer frame] In the present embodiment, one of the sashes 15 is arranged so as to be connected to the continuous inner wall portion 12. Specifically, the sash 15 is provided so as to be orthogonal to the continuous inner wall portion 12 in the continuous inner wall portion 12 that extends so as to bend to the second outer wall part 22 and is orthogonal to the end of the second outer wall part 22. The exterior 18 is continuously provided from the second outer wall part 22 to the continuous inner wall portion 12. Therefore, the exterior 18 of the second outer wall part 22 continuously enters the room.

[0049] Then, as shown in FIG. 9, at least a part of the sash outer frame 16 is embedded in the exterior finish 18 at the boundary between the outdoor and indoor sides in the continuous inner wall portion 12. Specifically, the sash outer frame 16 is attached to the continuous inner wall portion 12 such that a part of the sash outer frame 16 is disposed in the ventilation space SC between the exterior finish material 38 and the outer base material 36 in the continuous inner wall portion 12. By embedding the sash outer frame 16 in the exterior finish 18, the exterior finish 18 continuous from the outdoor to the indoor can appear more continuous than when the sash outer frame 16 is not embedded in the exterior finish 18. For this reason, the sense of unity with the outdoor increases indoors.

[0050] [Operation of the Present Embodiment] In the conventional building 1, the internal structure of the inner wall 9 is different from the internal structure of the outer wall 10. The inner wall 9 does not use a heat insulating material 35 and has a simpler structure than the outer wall 10. On the other hand, in the present embodiment, the building main body 2 includes a continuous inner wall portion 12. The continuous inner wall portion 12 is orthogonal and connected to the outer wall portion 11 so as to be continuous with the outer wall portion 11. The continuous inner wall portion 12 has the same internal structure as the outer wall portion 11. Thereby, a soundproof wall or a heat insulating wall can be provided indoors. Further, since the continuous inner wall portion 12 has the same structure as the outer wall portion 11, the continuous inner wall portion 12 can be efficiently formed in the construction of the building 1.

[0051] Furthermore, in the present embodiment, a part of the core structure 13 is configured as the continuous inner wall portion 12. In the continuous inner wall portion 12 extending so as to bend to the second outer wall portion 22, the exterior finish 18 is continuously provided from the second outer wall portion 22 to the continuous inner wall portion 12. The sash 15 is disposed so as to be orthogonal to the continuous inner wall portion 12. And the sash outer frame 16 is embedded in the exterior finish 18. For this reason, the sense of unity with the outdoor increases indoors.

[0052] Furthermore, the core structure 13 extends from the first floor 2A to the second floor 2B of the building 1. In the core structure 13, the internal space SA is configured with rooms for different uses in the first floor part and the second floor part. The internal structure of the core structure 13 is the same from the first floor 2A to the second floor 2B. In contrast, the outer structure of the core structure 13 differs depending on the use of the internal space SA. With such a structure, the degree of freedom in the design of the building 1 having the core structure 13 is increased.

[0053] [Effects of the present embodiment] The effects of the present embodiment will be described. (1) The building main body 2 includes an outer wall 10 and a continuous inner wall portion 12. The continuous inner wall portion 12 is orthogonal so as to be continuous with the outer wall portion 11 and is connected to the outer wall portion 11. At least a part of the continuous inner wall portion 12 is located indoors. The continuous inner wall portion 12 has the same internal structure as the outer wall portion 11. According to this configuration, a sound insulation wall or a heat insulation wall can be provided indoors. In addition, since the continuous inner wall portion 12 has the same structure as the outer wall portion 11, the continuous inner wall portion 12 can be efficiently formed in the construction of the building 1.

[0054] (2) In the outer wall portion 11, the exterior finish 18 of the outer wall portion 11 is provided on the outer wall portion 11 and the continuous inner wall portion 12 so as to be continuous from the outer wall portion 11 to the continuous inner wall portion 12. At least a part of the sash outer frame 16 is embedded in the exterior finish 18.

[0055] According to this configuration, it is possible to prevent the sash outer frame 16 from being seen from indoors or outdoors, or to make the sash outer frame 16 less conspicuous. As a result, when the sash window 17 is closed, the ratio of the window glass to the opening 6 of the building 1 can be increased. In addition, when the sash window 17 is opened, since the sash outer frame 16 is difficult to see, the opening 6 of the building 1 can be made to look beautiful. Specifically, in the continuous inner wall portion 12, since the exterior finish 18 appears to be continuous without being interrupted by the sash outer frame 16 toward the indoors, the opening 6 provided with the sash 15 can be made to look beautiful and the sense of unity between the indoors and the outdoors can be improved.

[0056] (3) Each of the four corners 3 of the building body 2 has a core structure 13. The four core structures 13 include a first outer wall portion 21, a second outer wall portion 22, a connecting wall 23 connected to be continuous with the second outer wall portion 22, a first column 31, a second column 32, a third column 33, and a fourth column 34. In at least one of the four core structures 13, the connecting wall 23 is configured as a continuous inner wall portion 12.

[0057] According to this configuration, the building 1 is supported by the four core structures 13. In this way, since the columns 30 can be concentrated at the four corners 3 of the building 1, the number of columns 30 provided inside the building 1 can be reduced. Thereby, the degree of freedom in the layout of the interior of the building 1 can be increased. And since the connecting wall 23 is configured as a continuous inner wall portion 12, the degree of freedom in the layout of the interior of the building 1 can be increased compared to the case where all of the connecting wall 23 is configured as an outer wall portion 11.

[0058] (4) In the building body 2, the first room 5 is configured to be surrounded by the first outer wall portion 21, the second outer wall portion 22, and the connecting wall 23 in the core structure 13. The connecting wall 23 is configured as a continuous inner wall portion 12. According to this configuration, the first room 5 can be used as a room with high sound insulation or heat insulation. The first room 5 can be used, for example, as a bathroom, a laundry room, a music room, a staircase room, or a study room.

[0059] (5) In the building body 2, the outdoor surrounding space SB is configured to be surrounded by the first outer wall portion 21, the second outer wall portion 22, and the connecting wall 23 in the core structure 13. The connecting wall 23 is configured as a part of the outer wall 10. According to this configuration, the first outer wall portion 21, the second outer wall portion 22, and the connecting wall 23 can provide an outdoor surrounding space SB surrounded by three walls outdoors. The outdoor surrounding space SB can be used, for example, as a windbreak or shaded relaxation space connected to the veranda 4.

[0060] (6) In the building 1, the first column 31, the second column 32, the third column 33, and the fourth column 34 are connected by the first connecting member 41 so as to form a rectangle in plan view. According to this configuration, the seismic resistance of the core structure 13 can be improved.

[0061] (7) In the building 1, the core structure 13 is connected to another core structure 13 by two second connecting members 42. According to this configuration, the seismic resistance of the building 1 can be improved.

[0062] (8) In the building 1, the core structure 13 is connected to another core structure 13 by two second connecting members 42, and is further connected to another core structure 13 by two second connecting members 42. Among the four second connecting members 42, the two second connecting members 42 located on the indoor side are connected to each other by a reinforcing member 43. According to this configuration, the seismic resistance of the building 1 can be improved.

[0063] (9) The building main body 2 has a first floor 2A and a second floor 2B. The core structure 13 extends from the first floor 2A to the second floor 2B. The core structure 13 has a connecting wall 23. The connecting wall 23 extends from the first floor 2A to the second floor 2B. The part of the connecting wall 23 on the first floor is configured as a continuous inner wall portion 12. The part of the connecting wall 23 on the second floor is configured as a part of the outer wall 10. The internal structure of the connecting wall 23 is the same from the first floor 2A to the second floor 2B. According to this configuration, the use of the connecting wall 23 on the second floor 2B can be made different from the use of the connecting wall 23 on the first floor 2A. Therefore, the degree of freedom in the use of the internal space SA of the core structure 13 can be improved.
