Description

[Technical Field]

[0001] The present disclosure relates to buildings. [Background technology]

[0002] There are known buildings in which the exterior wall materials are used for the interior of the rooms (for example, Patent Document 1). In the building of Patent Document 1, the same exterior wall material as the building is used for some of the interior walls of the rooms in the building. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 09-021243 Summary of the Invention [Problem to be solved by the invention]

[0004] In the prior art, exterior panels are simply used as interior decoration, and the structure of the interior walls in which the exterior panels are used is no different from other interior walls. However, there are cases where soundproofing or heat insulation is required indoors. From this perspective, we propose a new building. [Means for solving the problem]

[0005] (1) A building that solves the above problem is a building having a building body, the building body comprising an exterior wall and a continuous inner wall portion that is perpendicular to and connected to the exterior wall portion that is a part of the exterior wall, the continuous inner wall portion being arranged so that at least a portion of the continuous inner wall portion is located inside the room and has the same internal structure as the exterior wall portion.

[0006] According to this configuration, a soundproof wall or a heat-insulating wall can be provided indoors. Furthermore, since the continuous inner wall portion has the same structure as the outer wall portion, the continuous inner wall portion can be efficiently formed during the construction of a building.

[0007] (2) In the building described in (1) above, the building body further comprises a sash, the sash comprising a sash outer frame and a sash window movably attached to the sash outer frame, the exterior cladding of the exterior wall portion is provided on the exterior wall portion and the continuous inner wall portion so as to be continuous from the exterior wall portion to the continuous inner wall portion, and at least a portion of the sash outer frame is embedded in the exterior cladding.

[0008] This configuration makes it possible to make the sash outer frame invisible from inside or outside the room, or to make the sash outer frame less noticeable. This allows the ratio of window glass to the opening of the building to be increased when the sash window is closed. Also, when the sash window is open, the sash outer frame is less visible, allowing the opening of the building to look beautiful.

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

[0010] With this configuration, the building is supported by four core structures. In this way, columns can be concentrated at the four corners of the building, which reduces the number of columns required inside the building. This increases the degree of freedom in the layout of the building's interior. Furthermore, because the connecting walls are configured as continuous interior walls, the degree of freedom in the layout of the building's interior can be increased compared to when all of the connecting walls are configured as exterior walls.

[0011] (4) In the building described in (3) above, the building body has a first room inside, and the first room is configured to be surrounded by the first outer wall portion, the second outer wall portion, and the connecting wall of the core structure, and the connecting wall is configured as the continuous inner wall portion. With this configuration, the first room can be used as a room with high soundproofing or heat insulation. The first room can be used, for example, as a bathroom, laundry room, performance room, stairwell, or study room.

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

[0013] With this configuration, an outdoor enclosed space surrounded by three walls can be created outside the room using the first outer wall, the second outer wall, and the connecting wall. The outdoor enclosed space can be used, for example, as a windbreak or a shaded relaxation space connected to a balcony.

[0014] (6) In the building described in 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 form a rectangle in a plan view. This configuration improves the earthquake resistance of the core structure.

[0015] (7) In the building described in (3) above, the core structure is connected to another core structure by two second connecting members. This configuration can improve the earthquake resistance of the building.

[0016] (8) In the building described in (7) above, the core structure is connected to another core structure by two of the second connecting members, and is connected to yet another core structure by two of the second connecting members, and two of the four second connecting members located on the interior side of the building are connected to each other by a reinforcing member. This configuration can improve the earthquake resistance of the building. [Effects of the Invention]

[0017] According to the technology of the present disclosure, a building having soundproof or heat-insulating walls can be provided. [Brief explanation of the drawings]

[0019] A building 1 of this embodiment will be described with reference to FIGS. Examples of the building 1 include a detached house, an apartment building, a commercial facility, and a public facility. In this embodiment, the building 1 is a two-story house.

[0020] 1 and 2, the building 1 has a building body 2. The building body 2 includes an exterior wall 10 and a continuous interior wall portion 12.

[0021] The continuous inner wall portion 12 is perpendicular to the outer wall portion 11, which is a part of the outer wall 10, so as to be continuous with the outer wall portion 11, and is connected to the outer wall portion 11. The continuous inner wall portion 12 is configured as an extension of the outer wall portion 11. The continuous inner wall portion 12 may also be configured as a branch portion of the outer wall portion 11. The continuous inner wall portion 12 is provided so that at least a portion of the continuous inner wall portion 12 is located inside the room.

[0022] The continuous inner wall portion 12 has the same internal structure as the outer wall portion 11. In this embodiment, a connecting wall 23 (see below) in the core structure 13 is configured as the continuous inner wall portion 12.

[0023] The building 1 further includes a normal interior wall 14. The normal interior wall 14 has a normal wall structure that separates the interior of a room. The normal interior wall 14 does not have a thermal insulation material 35, or has a thermal insulation material 35 that is thinner than that of the exterior wall portion 11.

[0024] In this embodiment, the inner wall 9 is a wall disposed inside the room. The inner wall 9 includes a continuous inner wall portion 12 and a normal inner wall 14. The outer wall 10 includes an inner / outer partition wall separating the inside and outside of the room, and a wall disposed outside the room and connected to the inner / outer partition wall. In this embodiment, the outer wall 10 includes an outer wall portion 11. Examples of the outer wall portion 11 are a first outer wall portion 21 and a second outer wall portion 22 described below.

[0025] When a connecting wall 23, which will be described later, is located indoors, it is classified as an interior wall 9. When a connecting wall 23 is located outdoors, it is classified as an exterior wall 10. When the first floor portion of the connecting wall 23 is located indoors and the second floor portion is located outdoors, the first and second floor portions of the connecting wall 23 are classified into different wall types.

[0026] A specific example of building 1 will be described below. As shown in Figures 1 and 2, the building body 2 has four corners 3. In the building body 2, a core structure 13 is provided at each of the four corners 3 of the building body 2. Each of the four core structures 13 includes the same structure. As described below, each of the four core structures 13 includes at least a first outer wall portion 21 and a second outer wall portion 22 that is perpendicular to the first outer wall portion 21. Each of the four core structures 13 is arranged so that a corner portion 13A formed by the first outer wall portion 21 and the second outer wall portion 22 is located at a corner 3 of the building body 2.

[0027] The building body 2 further has a first room 5 inside the first floor 2A. The first room 5 is provided inside a core structure 13 as described below. The building body 2 may have a second room 7 other than the first room 5. The second room 7 is configured such that, for example, four core structures 13 are positioned 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 interior floor of the second floor 2B of the building main body 2. The veranda 4 is divided into four areas 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 separates the interior from the exterior. The sash 15 is disposed between the two core structures 13. The sash 15 is disposed so as to connect the two core structures 13 horizontally.

[0030] [Core Structure] The core structure 13 comprises a first outer wall portion 21, a second outer wall portion 22 perpendicular to the first outer wall portion 21, a connecting wall 23 connected to the second outer wall portion 22 so as to be continuous with the second outer wall portion 22, a first pillar 31, a second pillar 32, a third pillar 33, and a fourth pillar 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 to the second outer wall portion 22 so as to be perpendicular to the first outer wall portion 21. The connecting wall 23 may be connected to the end of the second outer wall portion 22 opposite to the first outer wall portion 21. The connecting wall 23 may be connected to an intermediate portion of the second outer wall portion 22 other than both ends.

[0032] The first exterior wall portion 21, the second exterior wall portion 22, and the connecting wall 23 have the same internal structure. Furthermore, the first exterior wall portion 21, the second exterior 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 columns 30, 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 each other from the first floor 2A to the second floor 2B.

[0034] The core structure 13 at the top right of FIG. 9 will be described as an example. In the core structure 13 in the upper right of Figure 9, the first floor portion of the first exterior wall portion 21 has an exterior material 38 on one side and an interior material 39 on the other side. The second floor portion of the first exterior wall portion 21 has exterior materials 38 on both sides. The second exterior wall portion 22 is configured in the same way as the first exterior wall portion 21.

[0035] In the core structure 13 in the upper right of Figure 9, the first floor portion of the connecting wall 23 has interior materials 39 on both sides. The second floor portion of the connecting wall 23 has two sections. The two sections of the second floor portion of the connecting wall 23 each have a different exterior structure. Specifically, in the second floor portion of the connecting wall 23, the portion that is located on the balcony 4 has exterior materials 38 on both sides. In the second floor portion of the connecting wall 23, the portion that separates the indoors and outdoors has exterior materials 38 on one side and interior materials 39 on the other side.

[0036] The arrangement of the first pillars 31 to the fourth pillars 34 in the core structure 13 will be described with reference to FIGS. The first pillar 31 is provided at the portion where the first outer wall portion 21 and the second outer wall portion 22 are connected to each other. The second pillar 32 is provided at the portion where the second outer wall portion 22 and the connecting wall 23 are connected to each other. The third pillar 33 is provided at a predetermined distance from the first pillar 31 on the first outer wall portion 21. The fourth pillar 34 is provided at a predetermined distance from the second pillar 32 on the connecting wall 23.

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

[0038] [Core structure connection structure] As shown in FIG. 5, the core structure 13 is connected to another core structure 13 by two second connecting members 42. Specifically, a 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 members 42 connect the pillars 30 of one core structure 13 to the pillars 30 of the other core structure 13. The second connecting members 42 are, for example, beams.

[0039] As shown in Fig. 6, of the four second connecting members 42 connected to the core structure 13 at the corners 3, the two second connecting members 42 located on the indoor side may be connected to each other by a reinforcing member 43. This allows the second floor to be reinforced. It also reduces the shaking of the core structure 13 due to 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 external wall portion 21, a second external 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 openings 24 in each of the first and second floor portions to allow people to enter the internal space SA. The core structure 13 may have sleeve walls 25 for installing fixtures in the openings 24.

[0041] As shown in Figure 7, the internal space SA of the first floor portion of each of the four core structures 13 is arranged indoors. In this case, the connecting walls 23 of the core structures 13 are configured as continuous inner wall portions 12. The internal space SA of the first floor portion of each of the core structures 13 is configured as a room suitable for a particular purpose.

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

[0043] As shown in FIG. 8 , for two of the four core structures 13, the internal space SA of the second floor of the core structure 13 is located indoors. For the other two of the four core structures 13, the internal space SA of the second floor of the core structure 13 is located outdoors and forms an outdoor enclosed space SB surrounded by the outer wall portion 11. The outdoor enclosed space SB is surrounded by a first outer wall portion 21, a second outer wall portion 22, and a connecting wall 23 of 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 wind-shielded or shaded relaxation space connected to the balcony 4. The outdoor enclosed space SB may also be configured as an area for hanging laundry. The outdoor enclosed space SB may also be configured as a storage area for outdoor furniture.

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

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

[0046] [Exterior wall structure and exterior continuous structure] The structure of the exterior wall portion 11 will be described with reference to Figure 9. Figure 9 is an enlarged view of the upper right corner portion of Figure 1. Note that in Figure 9, the television 50 shown in Figure 1 is omitted. The exterior wall portion 11 includes two or more pillars 30, a heat insulating material 35 arranged between the two pillars 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 furring strips 38A.

[0047] 9, in the portion of the building body 2 shown in FIG. 9, the continuous inner wall portion 12 has the same internal structure as the outer wall portion 11, and also has the same external structure as the outer wall portion 11. The exterior cladding 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.

[0048] [Sash Outer Frame Placement] In this 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 perpendicular to the continuous inner wall portion 12 in the continuous inner wall portion 12, which extends so as to bend toward the second outer wall portion 22 and is perpendicular to the end of the second outer wall portion 22. The exterior cladding 18 is provided continuously from the second outer wall portion 22 to the continuous inner wall portion 12. Therefore, the exterior cladding 18 of the second outer wall portion 22 extends continuously into the room.

[0049] As shown in Figure 9, at least a portion of the sash outer frame 16 is embedded in the exterior cladding 18 at the boundary between the indoor and outdoor areas in the continuous inner wall portion 12. Specifically, the sash outer frame 16 is attached to the continuous inner wall portion 12 so that a portion of the sash outer frame 16 is disposed in the ventilation space SC between the exterior cladding 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 cladding 18, the exterior cladding 18, which extends from the outdoor area to the indoor area, appears more continuous than if the sash outer frame 16 were not embedded in the exterior cladding 18. This increases the sense of unity between the indoor and outdoor areas.

[0050] [Operation of this embodiment] In the conventional building 1, the internal structure of the interior wall 9 is different from the internal structure of the exterior wall 10. The interior wall 9 does not use a heat insulating material 35 and has a simpler structure than the exterior wall 10. In contrast, in this embodiment, the building main body 2 has a continuous interior wall portion 12. The continuous interior wall portion 12 is perpendicular to and connected to the exterior wall portion 11 so as to be continuous with the exterior wall portion 11. The continuous interior wall portion 12 has the same internal structure as the exterior wall portion 11. This makes it possible to provide a soundproof wall or a heat insulating wall inside the room. Furthermore, because the continuous interior wall portion 12 has the same structure as the exterior wall portion 11, the continuous interior wall portion 12 can be efficiently formed during the construction of the building 1.

[0051] Furthermore, in this embodiment, a portion of the core structure 13 is configured as the continuous inner wall portion 12. In the continuous inner wall portion 12 that extends so as to bend toward the second outer wall portion 22, the exterior cladding 18 is provided continuously from the second outer wall portion 22 to the continuous inner wall portion 12. The sash 15 is arranged so as to be perpendicular to the continuous inner wall portion 12. The sash outer frame 16 is embedded in the exterior cladding 18. This increases the sense of unity between the indoor and outdoor spaces.

[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 made up of rooms with different uses on the first and second floors. The internal structure of the core structure 13 is the same from the first floor 2A to the second floor 2B. In contrast, the external structure of the core structure 13 differs depending on the use of the internal space SA. This structure increases the degree of freedom in the design of the building 1 having the core structure 13.

[0053] [Effects of this embodiment] The effects of this embodiment will be described. (1) The building body 2 comprises an exterior wall 10 and a continuous interior wall portion 12. The continuous interior wall portion 12 is perpendicular to and continuous with the exterior wall portion 11, and is connected to the exterior wall portion 11. At least a portion of the continuous interior wall portion 12 is located inside the room. The continuous interior wall portion 12 has the same internal structure as the exterior wall portion 11. This configuration makes it possible to provide a soundproof wall or a heat-insulating wall inside the room. Furthermore, because the continuous interior wall portion 12 has the same structure as the exterior wall portion 11, the continuous interior wall portion 12 can be efficiently formed during the construction of the building 1.

[0054] (2) In the outer wall portion 11, the exterior cladding 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 portion of the sash outer frame 16 is embedded in the exterior cladding 18.

[0055] This configuration makes it possible to make the sash outer frame 16 invisible from inside or outside the room, or to make the sash outer frame 16 less noticeable. This allows the ratio of window glass to the opening 6 of the building 1 to be increased when the sash window 17 is closed. Furthermore, because the sash outer frame 16 is difficult to see when the sash window 17 is open, the opening 6 of the building 1 can be made to look beautiful. Specifically, in the continuous inner wall portion 12, the exterior cladding 18 appears to be continuous without interruption toward the room through the sash outer frame 16, making the opening 6 in which the sash 15 is provided look beautiful and improving the sense of unity between the inside and outside of the room.

[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 the second outer wall portion 22 so as to be continuous with the 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] With this configuration, the building 1 is supported by four core structures 13. In this way, the columns 30 can be concentrated at the four corners 3 of the building 1, so the number of columns 30 installed inside the building 1 can be reduced. This increases the degree of freedom in the interior layout of the building 1. Furthermore, because the connecting walls 23 are configured as continuous inner wall portions 12, the degree of freedom in the interior layout of the building 1 can be increased compared to when all of the connecting walls 23 are configured as outer wall portions 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 of the core structure 13. The connecting wall 23 is configured as the continuous inner wall portion 12. With this configuration, the first room 5 can be used as a room with high soundproofing or heat insulation. The first room 5 can be used, for example, as a bathroom, laundry room, performance room, stairwell, or study room.

[0059] (5) In the building body 2, the outdoor enclosed 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 of the core structure 13. The connecting wall 23 is configured as a part of the outer wall 10. With this configuration, the outdoor enclosed space SB surrounded by three walls can be provided outside the room by the first outer wall portion 21, the second outer wall portion 22, and the connecting wall 23. The outdoor enclosed space SB can be used, for example, as a windbreak or shaded relaxation space connected to the balcony 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 a plan view. This configuration improves the earthquake resistance of the core structure 13.

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

[0062] (8) In the building 1, a 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. Of the four second connecting members 42, two second connecting members 42 located on the indoor side are connected to each other by reinforcing members 43. This configuration can improve the earthquake resistance of the building 1.

[0063] (9) The building 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 first floor portion of the connecting wall 23 is configured as a continuous interior wall portion 12. The second floor portion of the connecting wall 23 is configured as part of the exterior wall 10. The internal structure of the connecting wall 23 is the same from the first floor 2A to the second floor 2B. With 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. This increases the degree of freedom in how the internal space SA of the core structure 13 can be used.

[0064] <Modification> The above embodiment is an example of a form that the building 1 can take, and is not intended to limit the form. The building 1 can take a form different from the form exemplified in the above embodiment. Examples of such a form include a form in which part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0065] A normal inner wall 14 may be connected to the continuous inner wall portion 12. This allows the interior space of the building body 2 to be diversified.

[0066] Two openings 24 may be provided on the first or second floor of the core structure 13. This allows for greater flexibility in the layout of the building 1.

[0067] The core structure 13 may be provided in a part of the building 1 other than the corners 3. For example, the core structure 13 may be disposed in a part of the building 1 where the boundary between the interior and exterior is a straight line. In this case, the core structure 13 has a first exterior wall portion 21 located on the boundary between the interior and exterior and two continuous interior wall portions 12.

[0068] As shown in Fig. 7, an independent wall 26 may be provided in the building 1. The independent wall 26 is provided independently from the core structure 13.
