Description

TECHNICAL FIELD

[0001] The present disclosure relates to a building wall and a building. BACKGROUND ART

[0002] Reference to background art herein is not to be construed as an admission that such art constitutes common general knowledge.

[0003] Patent Literature l discloses a wall including panels. The wall includes a frame structure (a building structure as described in the Patent Literature), the panels (PC curtain walls as described in the Patent Literature) that are arranged in the frame structure, and coupling members (anchor bolts or fasteners as described in the Patent Literature) that couple the frame structure and the panels. CITATION LIST Patent Literature (Non-Patent Literature)

[0004] Patent Literature 1: JPH09-242233 SUMMARY OF INVENTION Technical Problem

[0005] Story drift may occur in a wall when a building sways due to winds, earthquakes, or other forces. When story drift occurs in a wall, force generated in an out-of-plane direction may move the panels of the wall in the out-of-plane direction and cause out-of-plane deformation. In this regard, in the walls of Patent Literature 1, the panels that are adjacent to each other in the vertical direction are engaged together to limit movement of the panels in the out-of-plane direction.

[0006] In the wall of Patent Literature 1, engagement of the panels constrains movement of 2025223829   07 Aug 2026 the panels in the out-of-plane direction. However, even if the panels are engaged together, depending on how the building sways, the panels may be moved by a great amount in the out-of-plane direction or in an in-plane direction. Preferred Solution to Problem

[0007] (1) In one general aspect, a building wall includes a frame structure, a panel arranged in the frame structure, a coupling member coupling the frame structure and the panel, and a movement restricting portion restricting movement of the panel relative to the frame structure in an out-of-plane direction intersecting the panel. The movement restricting portion includes a first projection projecting from the frame structure in a projecting direction intersecting the out-of-plane direction and directed from the frame structure toward the panel, a second projection projecting from the frame structure in the projecting direction and spaced apart from the first projection in the out-of-plane direction, and a third projection projecting from an end surface of the panel and arranged between the first projection and the second projection.

[0008] With this structure, the third projection, which projects from the end surface of the panel, is arranged between the first projection and the second projection. The first projection and the second projection are spaced apart from each other in the out-of-plane direction, and the third projection is arranged between the first projection and the second projection. This restricts movement of the third projection in the out-of-plane direction. The third projection projects from the end surface of the panel. Restriction of the movement of the third projection in the out-of-plane direction restricts movement of the panel in the out-of-plane direction. Therefore, out-of-plane deformation of the wall is restricted.

[0009] (2) The building wall according to (1) may include the coupling member fixed to the frame structure and the first projection and the second projection arranged on the coupling member. 2025223829   07 Aug 2026 With this structure, the first projection and the second projection are arranged on the coupling member. Thus, fixing the coupling member to the frame structure allows the first projection and the second projection to be provided.

[0010] (3) The building wall according to (1) or (2) may include the movement restricting portion including a first plate member arranged parallel to the out-of-plane direction and extending from the frame structure in the projecting direction, and a second plate member projecting from the end surface of the panel. The first plate member has one end connected to the frame structure. The first plate member has another end including a slit. The first projection and the second projection are located at two sides of the slit in the first plate member. The third projection is the second plate member. The second plate member is arranged in the slit.

[0011] With this structure, the first plate member, which includes the slit, defines the first projection and the second projection. Thus, the part of the movement restricting portion arranged on the frame structure can be formed readily.

[0012] (4) The building wall according to (1) or (2) may include the first projection including a first plate portion arranged intersecting the out-of-plane direction, the second projection including a second plate portion arranged intersecting the out-of-plane direction and spaced apart from the first plate portion in the out-of-plane direction, and the third projection arranged between the first plate portion and the second plate portion.

[0013] With this structure, the third projection is arranged between the first plate portion and the second plate portion, which are arranged to intersect with the out-of-plane direction. Thus, even if the third projection is moved in the in-plane direction, which intersects with the out-of-plane direction, the third projection will most likely remain in position between the first projection and the second projection. This restricts movement of the third projection in the out-of-plane direction in a preferable manner. 2025223829   07 Aug 2026

[0014] (5) The building wall according to (4) may include the movement restricting portion including a third plate member fixed to the frame structure and the first plate portion and the second plate portion welded to the third plate member.

[0015] With this structure, the first plate portion and the second plate portion are welded to the third plate member and thus fixes the third plate member to the frame structure. This forms the first plate portion and the second plate portion.

[0016] (6) The building wall according to (4) may include the first projection including a first rib extending in the out-of-plane direction from a surface of the first plate portion opposite a surface facing the second plate portion. The first rib supports the first plate portion in the out-of-plane direction. The second projection includes a second rib that extends in the out-of-plane direction from a surface of the second plate portion opposite a surface facing the first plate portion. The second rib supports the second plate portion in the out-of-plane direction.

[0017] With this structure, the first plate portion is supported by the first rib. This increases the strength of the first plate portion. Further, with this structure, the second plate portion is supported by the second rib. This increases the strength of the second plate portion.

[0018] (7) The building wall according to any one of (1) to (6) may include the frame structure including an upper member located above the panel, and a lower member located below the panel. The projecting direction extends from one of the upper member and the lower member to the other one of the upper member and the lower member. The movement restricting portion is arranged on each of four corners of the panel.

[0019] With this structure, the movement restricting portion is arranged at four corners of each panel. This restricts movement of the panel relative to the frame structure in the out-ofplane direction. (8) In another general aspect, a building includes the building wall according to any 2025223829   07 Aug 2026 of (1) to (7) in which the frame structure includes a horizontal member.

[0020] With this structure, the building is formed by the wall that restricts out-of-plane deformation. This limits deterioration of the building caused by the oscillation of the building. (9) In a further general aspect, a building includes the building wall according to any of (1) to (6) in which the frame structure includes a post.

[0021] With this structure, the building is formed by the wall that restricts out-of-plane deformation. This limits deterioration of the building caused by the oscillation of the building. Advantageous Effects of Invention

[0022] According to the structure of the building wall and the building of the present disclosure, out-of-plane deformation of the walls may be limited. BRIEF DESCRIPTION OF DRAWINGS

[0024] First Embodiment A building 1 and a wall 10 of the building 1 in accordance with a first embodiment will now be described with reference to Figs. 1 to 7.

[0025] Building As shown in Figs. 1 and 2, the building 1 is any one of a medium-scale building, a large-scale building, a medium-rise building, or a high-rise building. Fig. 1 shows a four-story residence as an example of the building 1. In countries such as the United Kingdom and Australia, “the first floor” as described in the specification will refer to “the ground 2025223829   07 Aug 2026 floor” and “the second floor” as described in the specification will refer to “the first floor.” The building 1 includes a foundation 2, exterior walls 3, a roof 4, and a frame structure 11. The frame structure 11 forms the framework of the building 1. The frame structure 11 includes posts 5, horizontal beams, and longitudinal beams. The exterior walls 3 are arranged on the frame structure 11. The roof 4 is also arranged on the frame structure 11.

[0026] The building 1 includes the wall 10. The exterior walls 3 are partially or entirely formed by the wall 10. When the building 1 includes interior walls, the interior walls may be partially or entirely formed by the wall 10.

[0027] Wall The wall 10 includes the frame structure 11, panels 20, coupling members 50, and movement restricting portions 70. The wall 10 is formed by coupling the panels 20 to a structural body 1A with the coupling members 50. In the present embodiment, the wall 10 includes panels 20 that form the exterior wall 3 of the first floor and panels 20 that form the exterior wall 3 of the second floor. A horizontal member 12 is arranged between the panels 20 in the exterior wall 3 of the first floor and the panels 20 in the exterior wall 3 of the second floor. This forms a continuous two-story load-bearing wall.

[0028] Frame Structure As shown in Fig. 2, the frame structure 11 forms a part of the structural body 1A of the building 1. In the present embodiment, the structural body 1A of the building 1 includes a foundation 2 and the frame structure 11.

[0029] The frame structure 11 includes, for example, horizontal members 12. The horizontal members 12 are, for example, horizontal beams. In one example, the horizontal members 12 are formed from steel. In another example, the horizontal members 12 are formed from H-shaped steel.

[0030] Fig. 2 shows an example of the wall 10 including four panels 20. An upper member 2025223829   07 Aug 2026 13 is located above the panels 20. A lower member 14 is located below two panels 20. The description hereafter will focus on the panels 20 located above a second horizontal member 12B as viewed in Fig. 2. The frame structure 11 includes the upper member 13 and the lower member 14. The frame structure 11 includes the horizontal members 12, namely, a first horizontal member 12A and the second horizontal member 12B, which is located below the first horizontal member 12A. In Fig. 2, the upper member 13 is the first horizontal member 12A, and the lower member 14 is the second horizontal member 12B.

[0031] The structural body 1A includes an opening 15. The opening 15 is surrounded by the upper member 13, the lower member 14, and the posts 5. The panels 20 are arranged in the opening 15. Panel The panels 20 are arranged in the frame structure 11. The panels 20 are not in contact with the structural body 1A. The panels 20 are not in contact with the frame structure 11. In a front view of the panels 20 taken in a state attached to the frame structure 11, the panels 20 are rectangular. Each panel 20 is coupled at its four corners to the frame structure 11.

[0032] The panel 20 is any one of an exterior member, a structural panel, or a curtain wall. The panel 20 of the present embodiment is a structural panel. The panel 20 is formed by plywood, which is a lamination of multiple members. Examples of members forming the panel 20 include a wooden board, a glued laminated timber, a resin plate, a thermal insulation resin member, an inorganic material, or the like. In one example, the panel 20 is formed by a wooden board, a resin plate, and a thermal insulation resin member. In another example, the panel 20 is formed by a cross laminated timber. In a further example, the panel 20 includes an inorganic material.

[0033] The exterior wall 3 may be formed so that the panels 20 are exposed to an indoor 2025223829   07 Aug 2026 space of the building 1. The surface of each panel 20 facing the indoor direction may be at least partially exposed to the indoor side. For example, when the panel 20 is formed by cross laminated timber, the panel 20 is arranged so that the surface facing the indoor space is exposed indoors. This structure allows the indoor side to be wood-grain.

[0034] The panels 20 are coupled to the frame structure 11 by the coupling members 50 without contacting the frame structure 11. The arrangement of the panels 20 forms a first space S1, between a lower surface 20B of each panel 20 and an upper surface 14A of the lower member 14, and a second space S2, between an upper surface 20A of each panel 20 and a lower surface 13B of the upper member 13.

[0035] Each panel 20 includes panel fastening portions 32. Preferably, the panel fastening portions 32 are arranged at the four corners of each panel 20. As shown in Fig. 4, an interior member 6 is arranged on a lower end of the surface of each panel 20 facing the indoor space so as to conceal the coupling member 50. An example of the interior member 6 is a baseboard. Backing material 7 and an exterior member 8 are arranged on an outer surface of the panel 20. The backing material 7 and the exterior member 8 extend downward across a lower end of the panel 20 so as to conceal the coupling member 50.

[0036] Panel Fastening Member As shown in Figs. 3 to 4, each panel 20 includes a panel fastening member 30 that is fixed to the panel 20. The panel fastening member 30 is a member forming the panel fastening portion 32. Fig. 3 is a cross-sectional view of the wall 10 taken along line C-C in Fig. 4. Fig. 4 is a cross-sectional view of the wall 10 taken along line A-A in Fig. 3. Fig. 5 is a cross-sectional view of the wall 10 taken along line B-B in Fig. 3. Among the four corners of the panel 20, three corners differing from the corner illustrated in Figs. 3 to 5 are also formed in a manner similar to the coupling structure illustrated in Figs. 3 to 5. 2025223829   07 Aug 2026

[0037] The panel fastening member 30 is, for example, formed from steel. The panel fastening member 30 is formed by a plate member. The panel fastening member 30 is, for example, formed by a metal plate. The panel fastening member 30 includes an embedded portion 31 and the panel fastening portion 32. The embedded portion 31 is inserted into a panel slit 25 in an end surface of the panel 20. The panel slit 25 is arranged at a middle of the panel 20 in the thickness direction. The embedded portion 31 is fixed to the panel 20 by fastening members 100. The embedded portion 31 includes first through holes 33 for insertion of the fastening members 100. Examples of a fastening member 100 include a set of a bolt and a nut, a rivet, a nail, or a drift pin. The same applies to the fastening members 100 described hereafter.

[0038] The panel fastening portion 32 is formed integrally with the embedded portion 31. The panel fastening portion 32 is a part to which a connecting member 60 is fastened. In one example, the panel fastening portion 32 is coupled to the coupling member 50 by two connecting members 60. The panel fastening portion 32 projects from the end surface of the panel 20. The panel fastening portion 32 includes second through holes 34 for insertion of the fastening members 100.

[0039] The panel fastening member 30 is fixed to the panel 20 so that a main surface of the panel fastening member 30 is parallel to a main surface of the panel 20. When the panel fastening member 30 is fixed to the panel 20, a center axis of each second through hole 34 in the panel fastening portion 32 is orthogonal to the main surface of the wall 10.

[0040] Coupling Member As shown in Fig. 2, the coupling members 50 couple the frame structure 11 and the panels 20. Each coupling member 50 is fixed to the frame structure 11. In order to arrange the panels 20 in the frame structure 11, the coupling member 50 is fixed to the upper surface 14A of the lower member 14 and to the lower surface 13B of the upper member 13. The 2025223829   07 Aug 2026 coupling members 50 are, for example, formed from steel. The coupling members 50 are, for example, formed by metal plates.

[0041] As shown in Fig. 3, each coupling member 50 includes a plate 51 and a bracket 52. The plate 51 is fixed by the fastening members 100 to either one of the upper surface 14A of the lower member 14 and the lower surface 13B of the upper member 13. The plate 51 includes third through holes 53 for insertion of the fastening members 100.

[0042] The bracket 52 is fixed to the plate 51. The bracket 52 is, for example, welded to the plate 51. The bracket 52 includes fourth through holes 57. When the bracket 52 is in a state attached to the plate 51, the fourth through holes 57 extend through the bracket 52 in a direction that is horizontal and orthogonal to the longitudinal direction of the bracket 52. The coupling member 50 is fixed to the horizontal member 12 so that the longitudinal direction of the horizontal member 12 coincides with the longitudinal direction of the plate 51. In this manner, when the coupling member 50 is fixed to the horizontal member 12, the center axis of each fourth through hole 57 in the bracket 52 is orthogonal to the main surface of the wall 10. The longitudinal direction of the plate 51 coincides with the longitudinal direction of the horizontal member 12.

[0043] If the panels 20 are directly attached to the horizontal member 12, when the building 1 sways, the panels 20 may be moved relative to the horizontal member 12. This may press the corners of the panels 20 against the horizontal member 12. In the wall 10, the panels 20 are attached to the horizontal member 12 by the connecting members 60 without contacting the horizontal member 12. Thus, even if the panels 20 are moved relative to the horizontal member 12, the corners of the panels 20 will not be pressed against the horizontal member 12.

[0044] The bracket 52 includes a coupling fastening portion 54. The coupling fastening portion 54 is connected to the panel fastening portion 32 of the panel 20 by the connecting 2025223829   07 Aug 2026 members 60. Connecting Member As shown in Fig. 3, the wall 10 further includes the connecting members 60. The connecting members 60 connect the panel 20 to the horizontal member 12 so that the panel 20 does not contact the horizontal member 12. The connecting members 60 are configured to be attached in a removeable manner to the panel 20 by the fastening members 100. The panel fastening portion 32 is connected to the coupling fastening portion 54 by the connecting members 60. In one example, a single panel fastening portion 32 is coupled to the corresponding coupling fastening portion 54 by two connecting members 60.

[0045] As shown in Fig. 6, the connecting member 60 includes a first member 61 and a second member 65. The second member 65 may have the same structure as the first member 61 or may have a structure differing from the first member 61. In the present embodiment, the second member 65 has the same structure as the first member 61.

[0046] The first member 61 and the second member 65 are formed by metal plates. The first member 61 and the second member 65 are, for example, formed from steel. Preferably, the first member 61 and the second member 65 are formed from low yield point steel.

[0047] The first member 61 includes a first protrusion 62 and two first fastening portions 63. The first protrusion 62 is arranged between the two first fastening portions 63. The first protrusion 62 is formed by bending a plate to protrude in a first direction D1, which extends toward one side in the thickness direction of the wall 10. The first protrusion 62, for example, includes a first horizontal portion 62A, a second horizontal portion 62B, and a first vertical portion 62C. The first horizontal portion 62A protrudes horizontally from one of the first fastening portions 63. The second horizontal portion 62B protrudes from the other first fastening portion 63. The first vertical portion 62C connects the first horizontal portion 62A 2025223829   07 Aug 2026 and the second horizontal portion 62B. Each first fastening portion 63 has fifth through holes 64 for insertion of the fastening members 100.

[0048] The second member 65 includes a second protrusion 66 and two second fastening portions 67. The second protrusion 66 is arranged between the two second fastening portions 67. The second protrusion 66 is formed by bending a plate to protrude in a second direction D2, which is the direction opposite the first direction D1. The second protrusion 66, for example, includes a third horizontal portion 66A, a fourth horizontal portion 66B, and a second vertical portion 66C. The third horizontal portion 66A protrudes horizontally from one of the second fastening portions 67. The fourth horizontal portion 66B protrudes horizontally from the other second fastening portion 67. The second vertical portion 66C connects the third horizontal portion 66A and the fourth horizontal portion 66B. Each second fastening portion 67 has sixth through holes 68 for insertion of the fastening members 100.

[0049] The second member 65 is coupled to the first member 61 by the fastening members 100. More specifically, the first member 61 and the second member 65 are coupled to each other by the fastening members 100 with the coupling fastening portion 54 and the panel fastening portion 32 held in between.

[0050] The connecting member 60 includes an expansion-contraction portion 60A and two fastening portions 60B. When the first member 61 and the second member 65 are in a coupled state, the first protrusion 62 and the second protrusion 66 form the expansioncontraction portion 60A. The force applied to the connecting member 60 expands or contracts the expansion-contraction portion 60A. When the first member 61 and the second member 65 are in a coupled state, one of the first fastening portions 63 and one of the second fastening portions 67 define one of the fastening portions 60B. The expansion-contraction portion 60A is located between the two fastening portions 60B. 2025223829   07 Aug 2026

[0051] The expansion-contraction portion 60A has a structure that changes the distance between the two fastening portions 60B. When the expansion-contraction portion 60A deforms, the connecting member 60 contracts and decreases the distance between the two fastening portions 60B or expands and increases the distance between the two fastening portions 60B. Movement of the panel 20 relative to the horizontal member 12 expands or contracts the expansion-contraction portion 60A. This limits the force applied by the panel 20 to the horizontal member 12.

[0052] Movement Restricting Portion As shown in Fig. 2, the movement restricting portions 70 are arranged at the four corners of each panel 20. The movement restricting portions 70 are arranged in the first space S1, which is between the lower surface 20B of each panel 20 and the upper surface 14A of the lower member 14, and the second space S2, which is between the upper surface 20A of each panel 20 and the lower surface 13B of the upper member 13.

[0053] As shown in Fig. 5, the movement restricting portion 70 restricts movement of the panel 20 relative to the frame structure 11 in an out-of-plane direction X1 that is the direction intersecting the panel 20. The movement restricting portion 70 includes a first projection 71, a second projection 72, and a third projection 73. The first projection 71 projects from the frame structure 11 in a projecting direction A1. The second projection 72 projects from the frame structure 11 in the projecting direction A1 and the second projection 72 is spaced apart from the first projection 71 in the out-of-plane direction X1. The projecting direction A1 is a direction intersecting the out-of-plane direction X1 and a direction from the frame structure 11 to the panel 20. For example, the projecting direction A1 is a direction extending from one of the upper member 13 and the lower member 14 to the other of the upper member 13 and the lower member 14. The projecting direction A1 shown in Fig. 5 illustrates the direction from the lower member 14 to the upper member 13. 2025223829   07 Aug 2026 In a view taken in the out-of-plane direction X1, the second projection 72 overlaps with the first projection 71.

[0054] The third projection 73 projects out of an end surface of the panel 20 in the direction opposite the projecting direction A1. The third projection 73, which projects from the end surface of the panel 20, is arranged between the first projection 71 and the second projection 72. At least a portion of the third projection 73 overlaps with the first projection 71 and the second projection 72 as viewed in the out-of-plane direction X1.

[0055] The first projection 71 and the second projection 72 are arranged on the coupling member 50. The first projection 71 and the second projection 72 are fixed to the plate 51 of the coupling member 50. The first projection 71 and the second projection 72 are arranged in a first plate member 74.

[0056] The movement restricting portion 70 includes the first plate member 74 and a second plate member 75. The first plate member 74 includes the first projection 71 and the second projection 72. The first plate member 74 is arranged in the out-of-plane direction X1 and extends from the frame structure 11 in the projecting direction A1. The second plate member 75 projects from the end surface of the panel 20.

[0057] Fig. 7 is a perspective view showing the first plate member 74 of the movement restricting portion 70. An end portion 74A of the first plate member 74 is connected to the frame structure 11. The end portion 74A of the first plate member 74 is fixed to the plate 51 of the coupling member 50. Thus, the coupling member 50 fixes the end portion 74A to the frame structure 11. Another end 74B of the first plate member 74 includes a slit 76. The slit 76 extends from an end of the first plate member 74 in the projecting direction A1 (refer to Fig. 5). The first projection 71 and the second projection 72 are located at the two sides of the slit 76 of the first plate member 74.

[0058] As shown in Fig. 3, the second plate member 75 is arranged on the panel fastening 2025223829   07 Aug 2026 member 30. The second plate member 75 is formed integrally with the embedded portion 31 of the panel fastening member 30. The second plate member 75 is arranged in the slit 76 of the first plate member 74. The thickness direction of the second plate member 75 coincides with the out-of-plane direction X1. The size of the second plate member 75 is set so that even if the panel 20 moves in the in-plane direction X2, the third projection 73 will be able to remain located between the first projection 71 and the second projection 72.

[0059] The third projection 73 is defined by part of or all of the second plate member 75. The third projection 73 is the portion of the second plate member 75 extending from the peripheral surface of the panel 20 and arranged in the slit 76 of the first plate member 74. The width of the slit 76 is set so that one surface of the second plate member 75 contacts the first projection 71 and the other surface of the second plate member 75 contacts the second projection 72.

[0060] Operation of Present Embodiment The first operation of the embodiment will now be described. Story drift may occur in the wall 10 when the building 1 sways due to winds, earthquakes, or other forces, and generate a force in the wall 10 in the out-of-plane direction X1. Movement of the wall 10 in the out-of-plane direction X1 may have undesirable effects, such as the separation of the panels 20 or damage inflicted to the interior of the indoor space of the building 1. In the wall 10, the third projection 73, which projects from the panel 20, is located between the first projection 71 and the second projection 72, which project from the frame structure 11. Thus, even if force acts on the wall 10 in the out-of-plane direction X1, movement of the panel 20 in the out-of-plane direction X1 will be restricted.

[0061] The second operation of the embodiment will now be described. The first projection 71 and the second projection 72 are fixed to the plate 51 of the coupling member 50. The plate 51 of the coupling member 50 is fixed by the fastening 2025223829   07 Aug 2026 members 100 to either one of the upper surface 14A of the lower member 14 and the lower surface 13B of the upper member 13. The coupling member 50 is arranged on the horizontal member 12 when manufacturing the horizontal member 12. This eliminates the processes that would have to be performed to arrange the first plate member 74 of the movement restricting portion 70 on the horizontal member 12 at a construction site of the wall 10.

[0062] Advantages of Present Embodiment The advantages of the present embodiment will now be described. (1-1) The building wall 10 includes the frame structure 11, the panel 20 arranged in the frame structure 11, the coupling member 50 coupling the frame structure 11 and the panel 20, and the movement restricting portion 70 restricting movement of the panel 20 relative to the frame structure 11 in the out-of-plane direction X1 intersecting the panel 20. The movement restricting portion 70 includes the first projection 71 projecting in the projecting direction A1 intersecting the out-of-plane direction X1 and directed from the frame structure 11 toward the panel 20, the second projection 72 projecting from the frame structure 11 in the projecting direction A1 and spaced apart from the first projection 71 in the out-of-plane direction X1, and the third projection 73 projecting from the end surface of the panel 20 and arranged between the first projection 71 and the second projection 72.

[0063] With this structure, the third projection 73, which projects from the panel 20, is arranged between the first projection 71 and the second projection 72. The first projection 71 and the second projection 72 are spaced apart from each other in the out-of-plane direction X1, and the third projection 73 is arranged between the first projection 71 and the second projection 72. This restricts movement of the third projection 73 in the out-of-plane direction X1. The third projection 73 projects from the end surface of the panel 20. Restriction of the movement of the third projection 73 in the out-of-plane direction X1 restricts movement of the panel 20 in the out-of-plane direction X1. Therefore, out-of-plane deformation of the 2025223829   07 Aug 2026 wall 10 is restricted.

[0064] (1-2) The first projection 71 and the second projection 72 are arranged on the coupling member 50. With this structure, the first projection 71 and the second projection 72 are arranged on the coupling member 50. Thus, the arrangement of the coupling member 50 allows the first projection 71 and the second projection 72 to be provided.

[0065] (1-3) The movement restricting portion 70 includes the first plate member 74 and the second plate member 75. The first plate member 74 is arranged parallel to the out-ofplane direction X1 and extends from the frame structure 11 in the projecting direction A1. The second plate member 75 projects from the end surface of the panel 20. The first plate member 74 has the end portion 74A connected to the frame structure 11 and the other end portion 74B of the first plate member 74 has the slit 76. The first projection 71 and the second projection 72 are located at two sides of the slit 76 in the first plate member 74. The third projection 73 is the second plate member 75. The second plate member 75 is arranged in the slit 76.

[0066] With this structure, the first plate member 74, which includes the slit 76, defines the first projection 71 and the second projection 72. Thus, the part of the movement restricting portion 70 arranged on the frame structure 11 can be formed readily.

[0067] (1-4) The frame structure 11 includes the upper member 13 located above the panel 20, and the lower member 14 located below the panel 20. The movement restricting portion 70 is arranged on each of four corners of the panel 20.

[0068] With this structure, the movement restricting portion 70 is arranged at four corners of each panel 20. This restricts movement of the panel 20 relative to the frame structure 11 in the out-of-plane direction X1. (1-5) The building 1 includes the wall 10 of the building 1. The frame structure 11 2025223829   07 Aug 2026 includes the horizontal member 12.

[0069] With this structure, the building 1 is formed by the wall 10 that restricts out-of-plane deformation. This limits deterioration of the building 1 caused by the oscillation of the building 1. Second Embodiment The building 1 and the wall 10 of the building 1 in accordance with a second embodiment will now be described with reference to Figs. 8 to 10. In the present embodiment, same reference numbers are given to those elements that are the same as the first embodiment. Such elements will not be described in detail.

[0070] In the present embodiment, the structure of the part of the movement restricting portion 70 arranged on the frame structure 11 differs from the first embodiment. Instead of the first plate member 74, the movement restricting portion 70 includes a first angle 81 and a second angle 82. The first angle 81 and the second angle 82 are each formed by L-shaped steel. The first angle 81 and the second angle 82 are arranged facing each other. The first angle 81 forms the first projection 71 and the second angle 82 forms the second projection 72.

[0071] The first projection 71 includes a first plate portion 83. The portion of the first angle 81 that faces the second angle 82 is the first plate portion 83. The second projection 72 includes a second plate portion 84. The portion of the second angle 82 that faces the first angle 81 is the second plate portion 84. The movement restricting portion 70 includes a third plate member 85. The first angle 81 and the second angle 82 are welded to the third plate member 85.

[0072] As shown in Figs. 9 and 10, the first plate portion 83 is arranged intersecting the out-of-plane direction X1. The second plate portion 84 is arranged intersecting the out-ofplane direction X1 and is spaced apart from the first plate portion 83 in the out-of-plane 2025223829   07 Aug 2026 direction X1. The third projection 73 is arranged between the first plate portion 83 and the second plate portion 84. The first plate portion 83 and the second plate portion 84 are welded to the third plate member 85. More specifically, the welding of the first angle 81 to the third plate member 85 welds the first plate portion 83 to the third plate member 85. Further, welding of the second angle 82 to the third plate member 85 welds the second plate portion 84 to the third plate member 85.

[0073] The third plate member 85 is fixed to the frame structure 11. The third plate member 85 is fixed to the frame structure 11 by the fastening members 100. The third plate member 85 includes seventh through holes 86 for insertion of the fastening members 100.

[0074] Advantages of Present Embodiment The advantages of the present embodiment will now be described. (2-1) The first projection 71 includes the first plate portion 83. The first plate portion 83 is arranged intersecting the out-of-plane direction X1. The second projection 72 includes the second plate portion 84 arranged intersecting the out-of-plane direction X1 and is spaced apart from the first plate portion 83 in the out-of-plane direction X1. The third projection 73 is arranged between the first plate portion 83 and the second plate portion 84.

[0075] With this structure, the third projection 73 is arranged between the first plate portion 83 and the second plate portion 84, which are arranged to intersect with the out-of-plane direction X1. Thus, even if the third projection 73 is moved in the in-plane direction X2, which intersects with the out-of-plane direction X1, the third projection 73 will most likely remain in position between the first projection 71 and the second projection 72. This restricts movement of the third projection 73 in the out-of-plane direction X1 in a preferable manner.

[0076] (2-2) The movement restricting portion 70 includes the third plate member 85. The third plate member 85 is fixed to the frame structure 11. The first plate portion 83 and the second plate portion 84 are welded to the third plate member 85. 2025223829   07 Aug 2026

[0077] With this structure, the first plate portion 83 and the second plate portion 84 are welded to the third plate member 85 and thus fixes the third plate member 85 to the frame structure 11. This forms the first plate portion 83 and the second plate portion 84.

[0078] Third Embodiment The building 1 and the wall 10 of the building 1 in accordance with the third embodiment will now be described with reference to Figs. 11 to 13. In the present embodiment, same reference numbers are given to those elements that are the same as the second embodiment. Such elements will not be described in detail.

[0079] In the present embodiment, the part of the movement restricting portion 70 arranged on the frame structure 11 differs from the second embodiment. Instead of the first angle 81 and the second angle 82, the movement restricting portion 70 includes a first T-shaped member 91, which is T-shaped in plan view, and a second T-shaped member 92, which is T-shaped in plan view. The first T-shaped member 91 and the second T-shaped member 92 are arranged facing each other. The first T-shaped member 91 defines the first projection 71, and the second T-shaped member 92 defines the second projection 72.

[0080] The first T-shaped member 91 includes the first plate portion 83. The portion of the first T-shaped member 91 that faces the second T-shaped member 92 is the first plate portion 83. The second T-shaped member 92 includes the second plate portion 84. The portion of the second T-shaped member 92 that faces the first T-shaped member 91 is the second plate portion 84. The second angle 82 is formed separately from the first angle 81.

[0081] As shown in Figs. 12 and 13, the first projection 71 includes a first rib 93. The first rib 93 extends in the out-of-plane direction X1 from a surface of the first plate portion 83 opposite the surface facing the second plate portion 84. The first rib 93 supports the first plate portion 83 in the out-of-plane direction X1. The first plate portion 83 and the first rib 93 are arranged in a T-shape in plan view. 2025223829   07 Aug 2026

[0082] The first projection 71 includes a fourth plate member 94. The fourth plate member 94 is formed integrally with the first plate portion 83 and the first rib 93. The fourth plate member 94 is fixed to the frame structure 11. The fourth plate member 94 is fixed to the frame structure 11. The fourth plate member 94 includes eighth through holes 98 for insertion of the fastening members 100.

[0083] The second projection 72 includes a second rib 95. The second rib 95 extends in the out-of-plane direction X1 from a surface of the second plate portion 84 that is opposite the surface facing the first plate portion 83. The second rib 95 supports the second plate portion 84 in the out-of-plane direction X1. The second plate portion 84 and the second rib 95 are arranged in a T-shape in plan view.

[0084] The second projection 72 includes a fifth plate member 96. The fifth plate member 96 is formed integrally with the second plate portion 84 and the second rib 95. The fifth plate member 96 is fixed to the frame structure 11. The fifth plate member 96 is fixed to the frame structure 11 by the fastening members 100. The fifth plate member 96 includes ninth through holes 99 for insertion of the fastening members 100.

[0085] In the present embodiment, the first plate portion 83 and the second plate portion 84 are fastened together by the fastening members 100. The first plate portion 83 and the second plate portion 84 each include an out-of-plane direction fastening portion 97 that includes an insertion hole for insertion of the fastening member 100. The out-of-plane direction fastening portion 97 restricts movement of one of the first plate portion 83 and the second plate portion 84 relative to the other one of the first plate portion 83 and the second plate portion 84.

[0086] Advantages of Present Embodiment The advantages of the present embodiment will now be described. (3) The first projection 71 includes the first rib 93. The first rib 93 extends in the 2025223829   07 Aug 2026 out-of-plane direction X1 from the surface of the first plate portion 83 opposite the surface facing the second plate portion 84. The first rib 93 supports the first plate portion 83 in the out-of-plane direction X1. The second projection 72 includes the second rib 95 that extends in the out-of-plane direction X1 from the surface of the second plate portion 84 opposite the surface facing the first plate portion 83. The second rib 95 supports the second plate portion 84 in the out-of-plane direction X1.

[0087] With this structure, the first plate portion 83 is supported by the first rib 93. This increases the strength of the first plate portion 83. Further, with this structure, the second plate portion 84 is supported by the second rib 95. This increases the strength of the second plate portion 84.

[0088] Modifications The above embodiments exemplify structures of the building 1 and the wall 10 of the building 1 and are not intended to impose any limitations. The building 1 and the wall 10 of the building 1 may differ from the structures exemplified in the above embodiments. Parts of the structures described in the embodiments may be replaced, changed, or omitted. Otherwise, a new feature may be added to the structure of the embodiments. Modifications of the embodiments will now be described.

[0089] The frame structure 11 may include the posts 5. In this modification, the first projection 71 and the second projection 72 are arranged projecting from the post 5 of the frame structure 11 in the horizontal direction. The third projection 73 projects from a side surface of the panel 20 in the horizontal direction. In this modification, the projecting direction A1, which is the direction the first projection 71 and the second projection 72 project toward, may be the direction from the post 5 at one side of the opening 15 to the post 5 at the other side of the opening 15. With this structure, the wall 10, which limits out-ofplane deformation, forms the building 1. This limits deterioration of the building 1 caused by 2025223829   07 Aug 2026 oscillation of the building 1.

[0090] In the first embodiment, the first projection 71 and the second projection 72 do not need to be arranged on the coupling member 50. For example, the first projection 71 and the second projection 72 may be directly coupled to the frame structure 11.

[0091] In the second embodiment, the first angle 81 and the second angle 82 may be arranged on the coupling member 50. In this modification, the first angle 81 and the second angle 82 may be arranged on the coupling member 50 of the plate 51 through the third plate member 85 or may be directly welded to the plate 51 of the coupling member 50.

[0092] In the third embodiment, the first T-shaped member 91 and the second T-shaped member 92 may be arranged on the plate 51 of the coupling member 50. As shown in Fig. 14, in the third embodiment, the out-of-plane direction fastening portion 97 may include a welding portion 97A instead of the insertion hole, which is for insertion of the fastening member 100. The welding portion 97A is formed by welding the first plate portion 83 and the second plate portion 84 together.

[0093] The movement restricting portion 70 may be arranged on at least one of the four corners of the panel 20. When the movement restricting portion 70 is arranged on at least one of the four corners of the panel 20, out-of-plane deformation of the wall 10 will be limited.

[0094] An example of the panel 20 arranged in the opening 15 of the frame structure 11 has been described. However, the movement restricting portion 70 may be applied to a wall where a panel 20 is spaced apart from the frame structure 11 in the out-of-plane direction X1. For example, the third projection 73, which projects from the peripheral surface of the panel 20, may be arranged extending from the panel 20 in the out-of-plane direction X1.

[0095] The horizontal member 12 may be formed from wood. In this modification, the first projection 71 and the second projection 72 may be directly fixed to the wooden horizontal 2025223829   07 Aug 2026 member 12 by the fastening members 100. The wall 10 of the building 1 of this modification allows for the construction of a wooden building that is any one of a medium-scale building, a large-scale building, a medium-rise building, or a high-rise building.
