[0003] [Patent Document 1] JP 2001-336294 A [Patent Document 2] JP 2002-004486 A Summary of the Invention [Problem to be solved by the invention]

[0004] Meanwhile, the demands of users or designers regarding the size and shape of outdoor spaces provided in buildings are becoming more diverse. However, with conventional framework structures, there are cases where the demands cannot be fully realized due to structural reasons. For this reason, there is room for improvement in walls and buildings from the viewpoint of increasing the design freedom of the layout or size of spaces in buildings. [Means for solving the problem]

[0005] (1) A structural wall that solves the above problem is a structural wall that supports a building body and includes a first wall portion, a second wall portion that is parallel to the first wall portion with a gap therebetween, a third wall portion that connects the first wall portion and the second wall portion, and a fourth wall portion that connects the first wall portion and the second wall portion at a position on the first wall portion and the second wall portion opposite the third wall portion. This configuration can increase the strength of the structural wall. Therefore, when the structural wall is incorporated as a part of the structural structure of a building, it is possible to increase the design freedom of the spatial arrangement or size.

[0006] (2) In the structural wall of (1) above, each of the first wall portion and the second wall portion includes a plurality of columns having webs, and in each of the first wall portion and the second wall portion, the plurality of columns are arranged such that the webs of the columns are aligned along the extension direction of the wall in a plan view. With this configuration, the first wall portion and the second wall portion can be made thin. This allows the structural wall to be made thin.

[0007] (3) In the structural wall of (1) or (2) above, a connecting portion is provided that connects the plurality of columns of the first wall portion and the plurality of columns of the second wall portion, the connecting portion including a first annular connecting portion that connects the upper ends of the columns of the first wall portion and the second wall portion in an annular shape. With this configuration, the strength of the structural wall can be improved.

[0008] (4) In the structural wall of (3) above, the connecting portion includes a second annular connecting portion, and the second annular connecting portion connects the columns in an annular shape at intermediate portions of the first wall portion and the second wall portion, respectively. With this configuration, the strength of the structural wall can be improved.

[0009] (5) In the skeleton wall of any one of (1) to (4) above, the distance between the width center of the first wall portion and the width center of the second wall portion is 300 mm or more and 700 mm or less. With this configuration, the width of the skeleton wall can be limited within a predetermined dimensional range.

[0010] (6) A structural wall that solves the above problems is a building having a structural structure, the structural structure comprising the structural wall according to any one of (1) to (5) above and a framework structure connected to the structural wall. With this configuration, since the building includes the structural wall, it is possible to increase the design freedom of the spatial arrangement or size in the building.

[0011] (7) A structural wall that solves the above problem is a building having a structural structure, the structural structure comprising a plurality of structural walls and a framework structure connected to the structural walls, each of the plurality of structural walls being the structural wall described in any one of (1) to (5) above, the plurality of structural walls being configured as exterior walls of the building, and each of the plurality of structural walls being arranged parallel to the other structural walls. With this configuration, the building includes a structural wall with high strength, so that the design freedom of the spatial arrangement or size of the building can be increased. Also, since each of the plurality of structural walls is arranged parallel to the other structural walls, a building with a distinctive appearance and excellent design can be provided.

[0012] (8) In the building of (7) above, some of the first groups of the plurality of structural walls are arranged in a row with a space between them, and the remaining second groups of the plurality of structural walls are arranged in a row with a space between them, the structural walls of the second groups are arranged parallel to the structural walls of the first groups, the structural walls of the first groups are connected to each other with connecting members, and the structural walls of the second groups are connected to each other with connecting members. This configuration can improve the earthquake resistance of the building.

[0013] (9) In the building according to (8) above, the second group of structural walls are arranged alternately with the first group of structural walls in a front view of the building. This configuration can improve the design of the building.

[0014] (10) In the building of any one of (7) to (9) above, a building body supported by the plurality of structural walls and the framework structure is provided between a first boundary surface formed along a first group of structural walls and a second boundary surface formed along a second group of structural walls, and the building body forms an indoor space and an outdoor space. According to this configuration, the indoor space and the outdoor space can be provided in the space between the first boundary surface and the second boundary surface.

[0015] (11) In the building of (10) above, the outdoor space includes a first outdoor space, which is provided to include an area between two adjacent structural walls in the first group when viewed from the front, or to include an area between two adjacent structural walls in the second group. This configuration makes it possible to connect the surrounding space of the building with the outdoor space of the building. This improves the openness of the outdoor space.

[0016] (12) In the building of (10) above, the outdoor space includes a second outdoor space, and the second outdoor space is provided along one of the structural walls of the first group, or along one of the structural walls of the second group. With this configuration, an outdoor space that is less exposed to wind and rain can be configured. Effect of the Invention

The second annular connector 18 connects the columns 15 in an annular shape at the intermediate portions of the first wall 11 and the second wall 12. Specifically, the second annular connector 18 is disposed between the columns 15 between the first floor 21 and the second floor 22 and the columns 15 between the second floor 22 and the flat roof 34. The second annular connector 18 connects the upper ends of the columns 15 between the first floor 21 and the second floor 22 in an annular shape. The second annular connector 18 also connects the lower ends of the columns 15 between the second floor 22 and the flat roof 34 in an annular shape.

[0032] The width of the body wall 3 is 600 mm or more and 1000 mm or less. The distance between the width center of the first wall portion 11 and the width center of the second wall portion 12 is 300 mm or more and 700 mm or less. In one example, the distance between the width center of the first wall portion 11 and the width center of the second wall portion 12 is 500 mm.

[0033] [Buildings] An example of a building 1 will be described with reference to FIG. 1 and FIGS. The building 1 has a first floor 21 and a second floor 22. The building 1 includes a plurality of structural walls 3, a first exterior wall 31, a second exterior wall 32 opposite the first exterior wall 31, a floor structure 33 constituting the floor of the second floor 22, and a flat roof 34. The first exterior wall 31, the second exterior wall 32, the floor structure 33, and the flat roof 34 include a frame structure 4.

[0034] The second outer wall 32 is disposed at a predetermined distance from the first outer wall 31. The distance between the first outer wall 31 and the second outer wall 32 is longer than the distance between the first boundary surface SX1 and the second boundary surface SX2. The second outer wall 32 is disposed in parallel with the first outer wall 31.

[0035] [Layout of Core Wall 3] 1, each of the multiple structural walls 3 extends from the foundation 30 to the flat roof 34. Each of the multiple structural walls 3 has the same height.

[0036] As shown in Fig. 4, one of the multiple structural walls 3 is arranged parallel to the other one. In one example, two structural walls 3 are arranged parallel to each other. The state in which two structural walls 3 are arranged parallel to each other (hereinafter, parallel arrangement state) is defined as follows. The parallel arrangement state of two structural walls 3 indicates a state in which a line along one structural wall 3 is parallel to a line along the other structural wall 3. Therefore, the parallel arrangement state includes a state in which two opposing structural walls 3 are parallel to each other, and a state in which two non-opposing structural walls 3 are parallel to each other.

[0037] When the building 1 has four or more structural walls 3, the structural walls 3 are arranged as follows: Some of the structural walls 3 in a first group GA are arranged in a row with a gap between them. The remaining structural walls 3 in a second group GB are arranged in a row with a gap between them. The structural walls 3 in the second group GB are arranged parallel to the structural walls 3 in the first group GA.

[0038] In this embodiment, the building 1 has six structural walls 3. The six structural walls 3 are divided into a first structural wall 3 of a first group GA and a second structural wall 3 of a second group GB.

[0039] The first group GA of structural walls 3 includes three structural walls 3. The three structural walls 3 of the first group GA are arranged in a row such that their longitudinal centerlines are aligned. The three structural walls 3 of the first group GA are arranged with a gap between them. The structural walls 3 of the first group GA are arranged between the first outer wall 31 and the second outer wall 32.

[0040] The structural walls 3 of the second group GB include three structural walls 3. The three structural walls 3 of the second group GB are arranged in a row so that their longitudinal centerlines are aligned. The three structural walls 3 of the second group GB are arranged at intervals. The structural walls 3 of the second group GB are arranged on the opposite side of the building 1 to the structural walls 3 of the first group GA. The structural walls 3 of the second group GB are arranged between the first exterior wall 31 and the second exterior wall 32.

[0041] The structural walls 3 of the second group GB may be arranged alternately with the structural walls 3 of the first group GA in a front view of the building 1. In this embodiment, the front surface of the building 1 is the first boundary surface SX1 or the second boundary surface SX2 (see below).

[0042] The structural walls 3 of the first group GA are connected to each other by connecting members 19. The structural walls 3 of the second group GB are connected to each other by connecting members 19. The connecting members 19 are made of steel. Examples of the steel include H-shaped steel and I-shaped steel. The steel is waterproofed. The connecting members 19 connect the upper end side surface of one structural wall 3 to the upper end side surface of another structural wall 3. The connecting members 19 are coupled to the first annular connecting portion 17.

[0043] In a plan view of the building 1, the shape formed by the first line L1 along the first exterior wall 31, the second line L2 along the second exterior wall 32, the third line L3 along the structural wall 3 of the first group GA, and the fourth line L4 along the structural wall 3 of the second group GB is rectangular.

[0044] [Building body] The building 1 includes a building body 20. The building body 20 is provided between a first boundary surface SX1 formed along the structural wall 3 of the first group GA and a second boundary surface SX2 formed along the structural wall 3 of the second group GB.

[0045] The building body 20 is supported by a plurality of structural walls 3 and a frame structure 4. The building body 20 constitutes an indoor space SB and an outdoor space SC. In this embodiment, the outdoor space SC includes a first outdoor space SC1 and a second outdoor space SC2. In this embodiment, the building body 20 includes a first exterior wall 31, a second exterior wall 32, a floor structure 33, and a flat roof 34.

[0046] [Indoor space] The indoor space SB is configured as a space used as an office, a space for recreation, a space for education, a space for sports, a space for relaxation, and a space for watching movies or paintings. The indoor space SB may be configured as a living space.

[0047] [First outdoor space] 4, the first outdoor space SC1 is provided to include an area between two adjacent structural walls 3 in the first group GA when viewed from the front. The first outdoor space SC1 is also provided to include an area between two adjacent structural walls 3 in the second group GB when viewed from the front.

[0048] The first outdoor space SC1 may be configured as a pilotis space or as a loggia space SD. In this embodiment, the first outdoor space SC1 is configured as a loggia space SD. On the first floor 21, the loggia area in which the first outdoor space SC1 is provided does not have a floor. The loggia area is configured as a courtyard that is continuous with the ground around the building body 20. The loggia area is open to the sky. Specifically, the loggia space SD includes an outdoor void SH that opens from the ground to the flat roof 34. The loggia space SD is connected to the sky above the flat roof 34 through the cutout 34A of the flat roof 34.

[0049] [Second outdoor space] The second outdoor space SC2 is provided so as to run along one of the structural walls 3 of the first group GA. Or, the additional second outdoor space SC2 is provided so as to run along one of the structural walls 3 of the second group GB. In this embodiment, the second outdoor space SC2 is provided so as to run along the structural wall 3 of the first group GA. And, the second outdoor space SC2 is provided so as to run along the structural wall 3 of the second group GB.

[0050] 4 and 5, the second outdoor space SC2 may be configured as a balcony space SF or may be configured as a deck space SE. In this embodiment, the building body 20 has the balcony space SF and the deck space SE.

[0051] On the first floor 21 of the building body 20, a deck floor 37 is provided in the deck area where the deck space SE is provided. The deck floor 37 is configured at the same height as the first floor indoor floor 36 of the indoor space SB. The deck space SE is provided adjacent to the loggia space SD. The deck space SE is continuous with the loggia space SD. Specifically, no partition wall is provided between the deck space SE and the loggia space SD. A balcony floor 39 is arranged above the deck area.

[0052] A balcony floor 39 is provided on the second floor 22 of the building body 20. The balcony floor 39 constitutes a balcony space SF. The balcony floor 39 is configured at the same height as the second floor indoor floor 38 of the indoor space SB. The balcony space SF is provided adjacent to the loggia space SD. The balcony space SF is continuous with the loggia space SD via a fence. A portion of the flat roof 34 is placed on top of the balcony floor 39.

[0053] [Floor structure] As shown in FIG. 5, the floor structure 33 constitutes the floor of the second floor 22 as described above. The floor structure 33 extends from the first exterior wall 31 to the second exterior wall 32. A floor opening 33A is provided in the floor structure 33. The building body 20 has an indoor void section SG. The indoor void section SG opens from the first floor 21 to the second floor 22 through the floor opening 33A. Six balcony floors 39 are connected to the floor structure 33. The floor structure 33 is connected to the structural wall 3 via the balcony floor 39. The floor structure 33 is supported by the structural wall 3 via the balcony floor 39.

[0054] Fig. 6 is a diagram showing the indoor space SB on the first floor 21. Fig. 6 is a diagram showing the deck space SE as viewed from inside the room. The indoor space SB is separated from the deck space SE by a first window sash 41. The indoor space SB is separated from the loggia space SD by a second window sash 42. The first window sash 41 and the second window sash 42 extend from the first floor indoor floor 36 to near the first floor ceiling 40. The first window sash 41 is disposed so as to be continuous with the second window sash 42. Therefore, the loggia space SD and deck space SE can be seen at a glance from inside the room.

[0055] [Operation of this embodiment] The operation of this embodiment will now be described. The structural wall 3 has a first wall portion 11, a second wall portion 12, a third wall portion 13, and a fourth wall portion 14. The first wall portion 11, the second wall portion 12, the third wall portion 13, and the fourth wall portion 14 are connected in a ring shape in a plan view. This increases the strength of the structural wall 3. Furthermore, in this embodiment, the structural wall 3 is made of reinforced concrete. This further increases the strength of the structural wall 3.

[0056] When a structural wall 3 is incorporated into a building 1 as part of a structural structure 2, the structural wall 3 supports the structural structure 2. For this reason, the structural structure 2 has a higher overall structural strength than a structural structure 2 that does not have a structural wall 3. Since the overall structural strength is higher, there is a structural margin for the required earthquake resistance. For this reason, there is a higher degree of freedom in spatial arrangement and design of size.

[0057] In this embodiment, the building 1 has a plurality of structural walls 3. The building body 20 is provided between the structural walls 3 of the first group GA arranged in a row and the structural walls 3 of the second group GB arranged in a row. The building body 20 is supported by the structural walls 3 of the first group GA and the structural walls 3 of the second group GB. This increases the strength of the building 1 as a whole. Since the strength of the entire structure increases, the building body 20 has a structural margin for the required earthquake resistance strength. This increases the degree of freedom in the layout of the space or the design freedom in the size of the space in the building body 20. Specifically, the indoor space SB in the building body 20 can be enlarged. In addition, there are fewer restrictions on the position where the indoor void part SG is provided in the building body 20. In addition, there is a high degree of freedom in the layout of the outdoor space SC. In addition, it is easy to increase the number of outdoor spaces SC or to enlarge the outdoor space SC.

[0058] [Effects of this embodiment] The effects of this embodiment will be described. (1) The structural wall 3 has a first wall portion 11, a second wall portion 12, a third wall portion 13, and a fourth wall portion 14. This configuration can increase the strength of the structural wall 3. Therefore, when the structural wall 3 is incorporated as part of the structural structure 2 in the building 1, it is possible to increase the design freedom of the spatial arrangement or size.

[0059] (2) In the structural wall 3, each of the first wall portion 11 and the second wall portion 12 includes a plurality of columns 15 having webs 15A. In each of the first wall portion 11 and the second wall portion 12, the plurality of columns 15 are arranged such that the webs 15A of the columns 15 are aligned along the extension direction DA of the first wall portion 11 or the second wall portion 12 in a plan view. This configuration allows the first wall portion 11 and the second wall portion 12 to be made thin. This allows the structural wall 3 to be made thin. This improves the design of the building 1.

[0060] (3) The structural wall 3 has a first annular connecting portion 17. The first annular connecting portion 17 connects in an annular shape the upper ends of the columns 15 of the first wall portion 11 and the second wall portion 12. This configuration can improve the strength of the structural wall 3.

[0061] (4) The structural wall 3 has a second annular connecting portion 18. The second annular connecting portion 18 annularly connects the pillars 15 at the intermediate portions of the first wall portion 11 and the second wall portion 12. This configuration can improve the strength of the structural wall 3.

[0062] (5) In the structural wall 3, the distance between the widthwise center of the first wall portion 11 and the widthwise center of the second wall portion 12 is 300 mm or more and 700 mm or less. With this configuration, the width of the structural wall 3 can be limited within a predetermined dimensional range.

[0063] (6) The skeleton structure 2 includes a skeleton wall 3 and a frame structure 4 connected to the skeleton wall 3. With this configuration, since the building 1 includes the skeleton wall 3, the design freedom of the spatial arrangement or size of the building 1 can be increased.

[0064] (7) The structural body 2 of the building 1 comprises a plurality of structural walls 3 and a frame structure 4 connected to the structural walls 3. The structural walls 3 are configured as the exterior walls of the building 1. Each of the structural walls 3 is arranged parallel to the others. With this configuration, the building 1 includes the structural walls 3, which increases the design freedom of the spatial arrangement or size of the building 1. Furthermore, since each of the structural walls 3 is arranged parallel to the others, the building 1 can be provided with a distinctive exterior and a highly designed appearance.

[0065] (8) In the building 1, some of the first group GA of the multiple structural walls 3 are arranged in a row with gaps between them. The remaining second group GB of the multiple structural walls 3 are arranged in a row with gaps between them. The structural walls 3 of the second group GB are arranged parallel to the structural walls 3 of the first group GA. The structural walls 3 of the first group GA are connected to each other with connecting members 19. The structural walls 3 of the second group GB are connected to each other with connecting members 19. With this configuration, the structural walls 3 are connected to each other, thereby improving the earthquake resistance of the building 1.

[0066] (9) In the building 1, the structural walls 3 of the second group GB are arranged alternately with the structural walls 3 of the first group GA in a front view of the building 1. With this configuration, the design of the building 1 can be improved.

[0067] (10) In the building 1, the building body 20 is provided between a first boundary surface SX1 formed along the structural wall 3 of the first group GA and a second boundary surface SX2 formed along the structural wall 3 of the second group GB. The building body 20 forms an indoor space SB and an outdoor space SC. With this configuration, the indoor space SB and the outdoor space SC can be provided in the space between the first boundary surface SX1 and the second boundary surface SX2. The structural wall 3 is more visible than the building body 20. In addition, the structural wall 3 is thicker than the other walls. This allows the building 1 to have an impression of being sturdy.

[0068] (11) The first outdoor space SC1 is provided to include an area between two adjacent structural walls 3 in the first group GA when viewed from the front. Alternatively, the first outdoor space SC1 is provided to include an area between two adjacent structural walls 3 in the second group GB when viewed from the front. This configuration makes it possible to connect the surrounding space of the building 1 with the outdoor space SC of the building 1. This improves the openness of the outdoor space SC. Also, it makes it easier for wind or light to enter the building 1.

[0069] (12) The second outdoor space SC2 is provided along one of the structural walls 3 of the first group GA. Alternatively, the second outdoor space SC2 is provided along one of the structural walls 3 of the second group GB. With this configuration, it is possible to configure the outdoor space SC that is less exposed to wind and rain.

[0070] <Modification> The above embodiment is an example of the form that the structural wall 3 and the building 1 can take, and is not intended to limit the form. The structural wall 3 and the building 1 can take a form different from the form exemplified in the above embodiment.
