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] A building disclosed in Patent Literature 1 includes a wall that has horizontal members (girders as described in the Patent Literature) and structural panels (reinforced wall frames for wooden frame structure as described in the Patent Literature). The structural panels are coupled to the horizontal members. The structural panels are arranged above and below the horizontal members. CITATION LIST Patent Literature (Non-Patent Literature)

[0004] Patent Literature 1: JPH11-100896A SUMMARY OF INVENTION Technical Problem

[0005] The structural panels may be moved when the building sways due to winds, earthquakes, or other forces. When the structural panels move, force is applied by the structural panels to the horizontal members. Movement of the structural panels when the building sways may deform the horizontal members. 2025223837   07 Aug 2026 Preferred Solution to Problem

[0006] (1) In one general aspect, a building wall includes a horizontal member, a first structural panel arranged above the horizontal member, a second structural panel arranged above the horizontal member adjacent to the first structural panel, and a first coupling member coupling the first structural panel and the second structural panel to the horizontal member. The first structural panel and the second structural panel are coupled to the horizontal member by the first coupling member without contacting the horizontal member. The first coupling member includes a first part located between the horizontal member and the first structural panel to couple the first structural panel to the horizontal member, and a second part located between the horizontal member and the second structural panel to couple the second structural panel to the horizontal member. At least a portion of the second part is formed integrally with the first part.

[0007] A shear force generated when structural panels are rotated is an example of the force applied to the horizontal member when the building sways. More specifically, when the building sways, the structural panels oscillate in substantially the same cycle. In other words, when the building sways, the first structural panel and the second structural panel are rotated in the same direction. In one example, in the proximity of the horizontal member, a lower edge of the first structural panel located toward the second structural panel is moved upward and a lower edge of the second structural panel located toward the first structural panel is moved downward. This generates shear force acting on a part of the horizontal member that receives force from two edges, namely, the lower edge of the first structural panel located toward the second structural panel and the lower edge of the second structural panel located toward the first structural panel.

[0008] In this regard, in the above structure, at least a portion of the second part is formed integrally with the first part. Thus, the portion where the first part is integrated with the second 2025223837   07 Aug 2026 part receives the force acting in the upward direction applied by the edge of the first structural panel and the force acting in the downward direction applied by the edge of the second structural panel. This limits the shear force applied to the horizontal member. Since the first coupling member limits the shear force acting on the horizontal member at the portion between the first structural panel and the second structural panel, deformation of the horizontal member that would be caused by the shear force is limited.

[0009] (2) The building wall according to (1) further includes a third structural panel arranged below the horizontal member, a fourth structural panel arranged below the horizontal member adjacent to the third structural panel, and a second coupling member coupling the third structural panel and the fourth structural panel to the horizontal member. The third structural panel and the fourth structural panel are coupled to the horizontal member by the second coupling member without contacting the horizontal member. The second coupling member includes a third part located between the horizontal member and the third structural panel to couple the third structural panel to the horizontal member, and a fourth part located between the horizontal member and the fourth structural panel to couple the fourth structural panel to the horizontal member. At least a portion of the fourth part is formed integrally with the third part. A middle line located between the third structural panel and the fourth structural panel coincides with a middle line located between the first structural panel and the second structural panel.

[0010] When the building sways, the third structural panel and the fourth structural panel are rotated in the same direction. In one example, in the proximity of the horizontal member, an upper edge of the third structural panel located toward the fourth structural panel is moved upward and an upper edge of the fourth structural panel located toward the third structural panel is moved downward. This generates shear force acting on the part of the horizontal member that receives force from two edges, namely, the upper edge of the third structural 2025223837   07 Aug 2026 panel located toward the fourth structural panel, and the upper edge of the fourth structural panel located toward the third structural panel.

[0011] In this regard, in the above structure, at least a portion of the fourth part is formed integrally with the third part. Thus, the portion where the third part is integrated with the fourth part receives the force acting in the upward direction applied by the edge of the third structural panel and the force acting in the downward direction applied by the edge of the fourth structural panel. This limits the shear force applied to the horizontal member. Since the second coupling member limits the shear force acting on the horizontal member at the portion between the third structural panel and the fourth structural panel, deformation of the horizontal member that would be caused by the shear force is limited.

[0012] (3) The building wall according to (2), in which the first coupling member is interlocked with the second coupling member by an interlocking member arranged inside the horizontal member. With this structure, the first coupling member is coupled to the second coupling member by the interlocking members. Thus, the force generated by the rotation of the structural panels arranged above the horizontal member is transmitted to the structural panels arranged below the horizontal member through the interlocking members. Therefore, the interlocking members limit the stress applied to the horizontal member by the forces generated by the rotation of the structural panels arranged above the horizontal member. This also limits deformation of the horizontal member caused by the force generated when the structural panels arranged above the horizontal member are rotated.

[0013] Further, “the force generated by the rotation of the structural panels arranged above the horizontal member” refers to the force applied to the horizontal member by the edges of the structural panels when the structural panels are rotated. Here, “the force applied to the 2025223837   07 Aug 2026 horizontal member by the edges” includes the pushing force and the pulling force applied by the structural panels to the horizontal member.

[0014] (4) The building wall according to (2) or (3), in which the first structural panel, the second structural panel, the third structural panel, and the fourth structural panel each have a panel fastening portion. The first coupling member and the second coupling member each have a coupling fastening portion. The panel fastening portion of the first structural panel and the panel fastening portion of the second structural panel are each connected to the coupling fastening portion of the first coupling member by a first connecting member. The panel fastening portion of the third structural panel and the panel fastening portion of the fourth structural panel are each connected to the coupling fastening portion of the second coupling member by a second connecting member differing from the first connecting member.

[0015] With this structure, the first connecting members connect the first structural panel and the second structural panel to the first coupling member. Further, the second connecting members connect the third structural panel and the fourth structural panel to the second coupling member.

[0016] (5) The building wall according to (4), in which the first coupling member includes a first plate that includes a portion of the first part and a portion of the second part, a first bracket that includes the coupling fastening portion in which the first plate is fixed to an upper surface of the horizontal member, and the first bracket extends upward from the first plate. The second coupling member includes a second plate that includes a portion of the third part and a portion of the fourth part, a second bracket that includes the coupling fastening portion in which the second plate is fixed to a lower surface of the horizontal member, and the second bracket extends downward from the second plate.

[0017] With this structure, in the first coupling member, the first bracket is fixed to the first plate and extends upward from the first plate. Thus, the first coupling member has a T-shaped 2025223837   07 Aug 2026 cross-section. This improves the durability of the first coupling member with respect to the force applied by the structural panels arranged above the horizontal member. In the same manner, the second bracket is fixed to the second plate and extends from the second plate. Thus, the second coupling member has a T-shaped cross-section. This improves the durability of the second coupling member with respect to the forces applied by the structural panels arranged below the horizontal member.

[0018] (6) In another general aspect, the building includes the building wall according to any one of (1) to (5). This structure allows for the formation of a wall that resists deformation even though the structural panels are coupled to the horizontal member. Thus, the durability of the building is improved.

[0021] A building 1 and a wall 10 of the building 1 in accordance with the present embodiment will now be described with reference to Figs. 1 to 9.

[0022] 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. The building 1 is preferably a wooden 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 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, upper horizontal members 17, 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.

[0023] 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.

[0024] Wall The wall 10 includes structural panels 20 coupled to a structural body 1A of the building 1 by coupling members 50. The structural body 1A includes a horizontal member 12. The structural panels 20 are arranged above and below the horizontal member 12. In the 2025223837   07 Aug 2026 present embodiment, the wall 10 includes a structural panel 20 that forms the exterior wall 3 of the first floor and a structural panel 20 that forms the exterior wall 3 of the second floor. The horizontal member 12 is arranged between the structural 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.

[0025] 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 includes the foundation 2 and the frame structure 11.

[0026] The horizontal member 12 is, for example, a horizontal beam. In one example, the horizontal member 12 is formed from wood. In another example, the horizontal member 12 is formed by a glue-laminated timber. Preferably, the dimension of the cross-section of the horizontal member 12 in the vertical direction is less than or equal to 450 mm. Preferably, the dimension of the cross-section of the horizontal member 12 in the horizontal direction is less than or equal to 120 mm.

[0027] The structural body 1A includes openings 14. The openings 14 of the structural body 1A includes a first opening 15 in the second floor and a second opening 16 in the first floor. The first opening 15 is surrounded by the horizontal member 12, the upper horizontal member 17 arranged above the horizontal member 12, and the posts 5. The second opening 16 is surrounded by the foundation 2, the horizontal member 12, and the posts 5.

[0028] Structural Panel The structural panels 20 are arranged in the openings 14 of the structural body 1A without contacting the structural body 1A. In a front view of the structural panels 20 taken in a state attached to the structural body 1A, the structural panels 20 are rectangular. Each structural panel 20 is coupled at its four corners to the structural body 1A. 2025223837   07 Aug 2026

[0029] The structural panels 20 are formed by plywood, which is a lamination of multiple members. Examples of members forming the structural panels 20 include wooden boards, glued-laminated timbers, resin plates, thermal insulation resin members, inorganic material, or the like. In one example, the structural panels 20 are each formed by laminating a wooden board, a resin plate, and a thermal insulation resin member. In another example, the structural panels 20 are each formed by an orthogonal glued-laminated timber. In a further example, the structural panels 20 include an inorganic material.

[0030] The exterior wall 3 may be formed so that the structural panels 20 are exposed to indoor space of the building 1. The surface of each structural panel 20 facing the indoor direction may be at least partially exposed to the indoor side. For example, when the structural panels 20 are formed by orthogonal glued-laminated timber, the structural panels 20 are arranged so that the surfaces facing the indoor space are exposed indoor. This structure allows the indoor side to be wood-grained.

[0031] The wall 10 includes a first structural panel 21 and a second structural panel 22 as the structural panels 20. Further, the wall 10 also includes a third structural panel 23 and a fourth structural panel 24 as the structural panels 20. More specifically, the wall 10 includes the horizontal member 12, the first structural panel 21, the second structural panel 22, and first coupling member 41. Further, the wall 10 includes the third structural panel 23, the fourth structural panel 24, and a second coupling member 42.

[0032] The first structural panel 21 is arranged above the horizontal member 12. The second structural panel 22 is arranged above the horizontal member 12 and is adjacent to the first structural panel 21. The first structural panel 21 and the second structural panel 22 are coupled to the horizontal member 12 by the first coupling member 41 so that the first structural panel 21 and the second structural panel 22 do not contact the horizontal member 12. The first structural panel 21 and the second structural panel 22 are arranged in the first opening 15 of 2025223837   07 Aug 2026 the structural body 1A. The arrangement of the first structural panel 21 forms a first space S1, between a lower surface 21B of the first structural panel 21 and an upper surface 12A of the horizontal member 12, and a second space S2, between an upper surface 21A of the first structural panel 21 and a lower surface 17B of the upper horizontal member 17. The arrangement of the second structural panel 22 forms a third space S3, between a lower surface 22B of the second structural panel 22 and the upper surface 12A of the horizontal member 12, and a fourth space S4, between an upper surface 22A of the second structural panel 22 and the lower surface 17B of the upper horizontal member 17.

[0033] The third structural panel 23 is arranged below the horizontal member 12. The fourth structural panel 24 is arranged below the horizontal member 12 and is adjacent to the third structural panel 23. The third structural panel 23 and the fourth structural panel 24 are coupled to the horizontal member 12 by the second coupling member 42 so that the third structural panel 23 and the fourth structural panel 24 do not contact the horizontal member 12. The third structural panel 23 and the fourth structural panel 24 are arranged in the second opening 16 of the structural body 1A. The arrangement of the third structural panel 23 forms a fifth space S5, between a lower surface 23B of the third structural panel 23 and an upper surface 2A of the foundation 2, and a sixth space S6, between an upper surface 23A of the third structural panel 23 and a lower surface 12B of the horizontal member 12. The arrangement of the fourth structural panel 24 forms a seventh space S7, between a lower surface 24B of the fourth structural panel 24 and the upper surface 2A of the foundation 2, and an eighth space S8, between an upper surface 24A of the fourth structural panel 24 and the lower surface 12B of the horizontal member 12.

[0034] A middle line C2 located between the third structural panel 23 and the fourth structural panel 24 coincides with a middle line C1 located between the first structural panel 21 and the second structural panel 22. In a front view taken in a state in which the structural 2025223837   07 Aug 2026 panels 20 are attached to the structural body 1A, the middle line C1 is a line located at the middle of an end surface of the first structural panel 21 that is located toward the second structural panel 22 and an end surface of the second structural panel 22 that is located toward the first structural panel 21. In a front view taken in a state in which the structural panels 20 are attached to the structural body 1A, the middle line C2 is a line located at the middle of an end surface of the third structural panel 23 that is located toward the fourth structural panel 24 and an end surface of the fourth structural panel 24 that is located toward the third structural panel 23. In a front view taken in a state in which the structural panels 20 are attached to the structural body 1A, the end surface of the first structural panel 21 located toward the second structural panel 22 is flush with the end surface of the third structural panel 23 located toward the fourth structural panel 24. In a front view taken in a state in which the structural panels 20 are attached to the structural body 1A, the end surface of the second structural panel 22 that is located toward the first structural panel 21 is flush with the end surface of the fourth structural panel 24 that is located toward the third structural panel 23.

[0035] The first structural panel 21, the second structural panel 22, the third structural panel 23, and the fourth structural panel 24 each include panel fastening portions 32. Preferably, the panel fastening portions 32 are arranged at the four corners of each structural panel 20.

[0036] As shown in Fig. 4, an interior member 6 is arranged on the lower end of the surface of each structural panel 20 that faces 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 structural panel 20. The backing material 7 and the exterior member 8 extend downward from a lower end of the structural panel 20 so as to conceal the coupling member 50.

[0037] Panel Fastening Member As shown in Figs. 3 and 4, each structural panel 20 includes a panel fastening 2025223837   07 Aug 2026 member 30 that is fixed to the structural 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 B-B in Fig. 4. Fig. 4 is a cross-sectional view of the wall 10 taken along line A-A in Fig. 3.

[0038] Fig. 4 is an enlarged cross-sectional view of the portion where the horizontal member 12 and the second structural panel 22 are coupled. The portions where the horizontal member 12 is coupled to each structural panel 21, 23, and 24 are also formed in the same manner as the coupling structure illustrated in Fig. 4.

[0039] The panel fastening member 30 is 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 slit 25 in an end surface of the structural panel 20. The slit 25 is arranged at the middle of the structural panel 20 in the width direction. The embedded portion 31 is fixed to the structural panel 20 by fastening members 80. The embedded portion 31 includes first through holes 33 for insertion of the fastening members 80. Examples of a fastening member 80 include a set of a bolt and a nut, a rivet, a nail, or a drift pin. The same applies to the fastening members 80 described hereafter.

[0040] 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 fastened to the coupling member 50 by two connecting members 60. The panel fastening portion 32 projects from the end surface of the structural panel 20. The panel fastening portion 32 includes second through holes 34 for insertion of the fastening members 80.

[0041] The panel fastening member 30 is fixed to the structural panel 20 so that a main surface of the plate member forming the panel fastening member 30 is parallel to a main 2025223837   07 Aug 2026 surface of the structural panel 20. When the panel fastening member 30 is fixed to the structural 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.

[0042] Coupling Member As shown in Fig. 3, the coupling member 50 is coupled to the horizontal member 12 and the structural panels 20.

[0043] The first coupling member 41 is fixed to the upper surface 12A of the horizontal member 12 by the fastening members 80. The first coupling member 41, which acts as the coupling member 50, couples the first structural panel 21 and the second structural panel 22 to the horizontal member 12. The first coupling member 41 includes a first part 41A and a second part 41B. The first part 41A, which is located between the horizontal member 12 and the first structural panel 21, couples the first structural panel 21 and the horizontal member 12. The second part 41B, which is located between the horizontal member 12 and the second structural panel 22, couples the second structural panel 22 and the horizontal member 12. The first part 41A is located in the first space S1, which is between the lower surface 21B of the first structural panel 21 and the upper surface 12A of the horizontal member 12. In one example, the first part 41A is coupled to the panel fastening portion 32 of the first structural panel 21 by the two connecting members 60. The second part 41B is located in the third space S3, which is between the lower surface 22B of the second structural panel 22 and the upper surface 12A of the horizontal member 12. In another example, the second part 41B is coupled to the panel fastening portion 32 of the second structural panel 22 by the two connecting members 60.

[0044] The second coupling member 42 is fixed to the lower surface 12B of the horizontal member 12 by the fastening members 80. The second coupling member 42, which acts as the coupling member 50, couples the third structural panel 23 and the fourth structural panel 24 to 2025223837   07 Aug 2026 the horizontal member 12. The second coupling member 42 includes a third part 42A and a fourth part 42B. The third part 42A, which is located between the horizontal member 12 and the third structural panel 23, couples the third structural panel 23 and the horizontal member 12. The fourth part 42B, which is located between the horizontal member 12 and the fourth structural panel 24, couples the fourth structural panel 24 and the horizontal member 12. The third part 42A is located in the sixth space S6, which is between the upper surface 23A of the third structural panel 23 and the lower surface 12B of the horizontal member 12. In one example, the third part 42A is coupled to the panel fastening portion 32 of the third structural panel 23 by the two connecting members 60. The fourth part 42B is located in the eighth space S8, which is between the upper surface 24A of the fourth structural panel 24 and the lower surface 12B of the horizontal member 12. In another example, the fourth part 42B is coupled to the panel fastening portion 32 of the fourth structural panel 24 by the two connecting members 60.

[0045] An example of the coupling member 50 will now be described with reference to Figs. 5 and 6. Figs. 5 and 6 show an example of the first coupling member 41, which acts as the coupling member 50. The second coupling member 42 is substantially identical in structure to the first coupling member 41. The coupling member 50 is, for example, formed from steel. The coupling member 50 is, for example, formed by a metal plate.

[0046] The coupling member 50 includes a plate 51 and brackets 52. The plate 51 is fixed to the horizontal member 12 by the fastening members 80. Third through holes 53 for insertion of the fastening members 80 extend through the plate 51. The fastening members 80 inserted through the third through holes 53 fix the coupling member 50 to the horizontal member 12. The third through holes 53 are located at the middle of the plate 51 in the lateral direction of the plate 51.

[0047] The brackets 52 are fixed to the plate 51. The brackets 52 are, for example, welded to 2025223837   07 Aug 2026 the plate 51. The brackets 52 include fourth through holes 57. The fourth through holes 57 extend through intermediate brackets 55. When the coupling member 50 is fixed to the horizontal member 12, a center axis of each fourth through hole 57 in each bracket 52 is orthogonal to the main surface of the wall 10.

[0048] The brackets 52 include the intermediate brackets 55 extending in the longitudinal direction of the plate 51, and end brackets 56 extending in the lateral direction of the plate 51 in plan view.

[0049] The intermediate brackets 55 are located at the middle position of the plate 51 in the lateral direction. The intermediate brackets 55 are interrupted in the longitudinal direction of the plate 51 at portions where third through holes 53 extend through the plate 51. The end brackets 56 are continuous with the two longitudinal ends of the intermediate brackets 55.

[0050] The intermediate brackets 55 and the end brackets 56 extend vertically from the plate 51. In a state in which the coupling member 50 is fixed to the horizontal member 12, the intermediate brackets 55 and the end brackets 56 project from the plate 51 in the vertical direction. The connecting members 60 are fastened to the intermediate brackets 55. In a state in which the coupling member 50 is attached to the horizontal member 12, the coupling member 50 has a T-shaped cross-section formed by the plate 51 and the intermediate bracket 55. When the coupling member 50 is attached to a horizontal member 12, the coupling member 50 has a T-shaped cross-section formed by the plate 51 and the end bracket 56.

[0051] As shown in Fig. 3, the longitudinal direction of the plate 51 corresponds to the longitudinal direction of the horizontal member 12. In the first coupling member 41, one side of the plate 51 in the longitudinal direction defines the first part 41A, and the other side of the plate 51 in the longitudinal direction defines the second part 41B. In the second coupling member 42, one side of the plate 51 in the longitudinal direction defines the third part 42A, and the other side of the plate 51 in the longitudinal direction defines the fourth part 42B. 2025223837   07 Aug 2026

[0052] The first coupling member 41 includes a first plate 43 that includes a portion of the first part 41A and a portion of the second part 41B, and a first bracket portion 44 that includes a coupling fastening portion 54. The first plate 43 is fixed to the upper surface 12A of the horizontal member 12. The first bracket portion 44 extends upward from the first plate 43. The second coupling member 42 includes a second plate 45 that includes a part of the third part 42A and a part of the fourth part 42B, and a second bracket portion 46 that includes the coupling fastening portion 54. The second plate 45 is fixed to the lower surface 12B of the horizontal member 12. The second bracket portion 46 extends downward from the second plate 45.

[0053] The first part 41A is the part of the first coupling member 41 located in the first space S1. The second part 41B is the part of the first coupling member 41 located in the third space S3. At least a portion of the second part 41B is formed integrally with the first part 41A. For example, the first plate 43 of the second part 41B is formed integrally with the first plate 43 of the first part 41A.

[0054] The third part 42A is the part of the second coupling member 42 located in the sixth space S6. The fourth part 42B is the part of the second coupling member 42 located in the eighth space S8. At least a portion of the fourth part 42B is formed integrally with the third part 42A. For example, the second plate 45 of the fourth part 42B is formed integrally with the second plate 45 of the third part 42A.

[0055] The coupling member 50 includes the coupling fastening portions 54. In one example, a connecting member 60 is fastened to each coupling fastening portion 54. The coupling fastening portion 54 is connected to the panel fastening portion 32 of the structural panel 20 by the connecting members 60. The first coupling member 41 and the second coupling member 42 each include the coupling fastening portions 54. As shown in Fig. 5, each 2025223837   07 Aug 2026 coupling fastening portion 54 is a portion of the bracket 52 that includes fourth through holes 57.

[0056] Connecting Member As shown in Fig. 3, the wall 10 further includes the connecting members 60. The connecting members 60 connect the structural panels 20 to the coupling members 50 so that the structural panels 20 do not contact the horizontal member 12. The connecting members 60 are configured to be attached in a removable manner to the coupling members 50 by the fastening members 80. The wall 10 includes first connecting members 60X, arranged above the horizontal member 12, and second connecting members 60Y, arranged below the horizontal member 12, as the connecting members 60. The first connecting members 60X differ from the second connecting members 60Y. The panel fastening portion 32 of the first structural panel 21 and the panel fastening portion 32 of the second structural panel 22 are each connected to the coupling fastening portion 54 of the first coupling member 41 by the first connecting members 60X. The panel fastening portion 32 of the third structural panel 23 and the panel fastening portion 32 of the fourth structural panel 24 are each connected to the coupling fastening portion 54 of the second coupling member 42 by the second connecting members 60Y.

[0057] As shown in Fig. 7, each 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.

[0058] 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. 2025223837   07 Aug 2026

[0059] 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 and the second horizontal portion 62B. Each first fastening portion 63 has fifth through holes 64 for insertion of the fastening members 80.

[0060] The second member 65 includes a second protrusion 66 and two second fastening portions 67. The second protrusion 66 is arranged between the two 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 of 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 80.

[0061] The second member 65 is coupled to the first member 61 by the fastening members 80. More specifically, the first member 61 and the second member 65 are coupled to each other by the fastening members 80 with the coupling fastening portion 54 and the panel fastening portion 32 held in between. 2025223837   07 Aug 2026

[0062] 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 expansion-contraction 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.

[0063] 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 structural panel 20 relative to the horizontal member 12 expands or contracts the expansion-contraction portion 60A. This limits the force applied by the structural panel 20 to the horizontal member 12.

[0064] Interlocking Member As shown in Figs. 3 and 4, the wall 10 further includes interlocking members 70. The first coupling member 41 is interlocked with the second coupling member 42 by the interlocking members 70. In one example, the first coupling member 41 is interlocked with the second coupling member 42 by four interlocking members 70. The interlocking members 70 are arranged inside the horizontal member 12. Each interlocking member 70 is arranged in a hole 18 that extends from the upper surface 12A of the horizontal member 12 to the lower surface 12B of the horizontal member 12.

[0065] Each interlocking member 70 includes a main body 71. The main body 71 is arranged in the hole 18 and extends through the hole 18. The main body 71 is, for example, formed 2025223837   07 Aug 2026 from steel. The main body 71 is, for example, formed by a round steel bar. The length of the main body 71 is set in correspondence with the height of the horizontal member 12.

[0066] When the first coupling member 41 is detached from the horizontal member 12, a first end of the main body 71 is exposed from the upper surface 12A of the horizontal member 12. When the second coupling member 42 is detached from the horizontal member 12, a second end of the main body 71 is exposed from the lower surface 12B of the horizontal member 12. The first end of the main body 71 is in contact with a lower surface 41Y of the first coupling member 41. The second end of the main body 71 is in contact with an upper surface 42X of the second coupling member 42. The first end of the main body 71 includes a first interlocking part 72. The second end of the main body 71 includes a second interlocking part 73.

[0067] A fastening member 80 arranged in a third through hole 53 of the first coupling member 41 is fastened to the first interlocking part 72. A fastening member 80 arranged in a through hole 53 of the second coupling member 42 is fastened to the second interlocking part 73. The first interlocking part 72 and the second interlocking part 73 each include a fastening hole 74 where the fastening member 80 is fastened. When the fastening member 80, which is arranged in the third through hole 53 of the first coupling member 41, is fastened to the fastening hole 74 of the first interlocking part 72, the first coupling member 41 is fixed to the upper surface 12A of the horizontal member 12. When the fastening member 80, which is arranged in the third through hole 53 of the second coupling member 42, is fastened in the fastening hole 74 of the second interlocking part 73, the second coupling member 42 is fixed to the lower surface 12B of the horizontal member 12.

[0068] Operations of Embodiment A first operation of the present embodiment will now be described. 2025223837   07 Aug 2026 The structural panels 20 may be moved when the building 1 sways due to winds, earthquakes, or other forces. When the structural panels 20 move, force is applied by the structural panels 20 to the horizontal member 12.

[0069] Fig. 8 illustrates a referential example in which a conventional wall 91 includes structural panels 93, 94, 95, and 96 that are directly attached to a horizontal member 92. When a building 90 sways, the structural panels 93, 94, 95, and 96 oscillate in substantially the same cycle. In other words, when the building 90 sways, the structural panels 93, 94, 95, and 96 are rotated in the same direction. In the example of Fig. 8, when the building 90 sways, the structural panels 93, 94, 95, and 96 in the wall 91 of the building 90 are moved so as to rotate counterclockwise as indicated by the arrows. A connecting portion 97 of the horizontal member 92, connected to the structural panels 93, 94, 95, and 96, receive force from the edges of the structural panels 93, 94, 95, and 96. This generates a shear force in the horizontal member 92 in the proximity of the connecting portion 97.

[0070] The force applied to the connecting portion 97 may be reduced by omitting the two structural panels 93 and 96 or by omitting the two structural panels 94 and 95 so that only two panels are arranged at diagonal positions with the horizontal member 92 located in between. However, the arrangement of the structural panels in only the diagonal positions with the horizontal member 92 located in between imposes design restrictions, such as the outer appearance of the building 90 and the layout of the windows. As another option, a horizontal member 92 may be formed from steel to improve durability. However, from the viewpoint of easiness for demolishing, sorting, and recycling of the wall 10, it is preferred that wood be used for the horizontal member 92.

[0071] With reference to Fig. 9, the force applied from the structural panels 21, 22, 23, and 24 of the wall 10 to the horizontal member 12 will now be described. Fig. 9 illustrates an example where the building 1, which includes the wall 10, sways thereby moving and rotating 2025223837   07 Aug 2026 each of the structural panels 21, 22, 23, and 24 counterclockwise. In the wall 10, the first part 41A of the first coupling member 41, which is located between the horizontal member 12 and the first structural panel 21, is formed integrally with the second part 41B, which is located between the horizontal member 12 and the second structural panel 22. Thus, the first coupling member 41 receives a force generated by an edge of the first structural panel 21 and acting in an upward direction and a force generated by an edge of the second structural panel 22 and acting in a downward direction. Further, the third part 42A of the second coupling member 42, which is located between the horizontal member 12 and the third structural panel 23, is formed integrally with the fourth part 42B, which is located between the horizontal member 12 and the fourth structural panel 24. Thus, the second coupling member 42 receives a force generated by an edge of the third structural panel 23 and acting in an upward direction and a force generated by an edge of the fourth structural panel 24 and acting in a downward direction.

[0072] The second operation of the present embodiment will now be described. In the wall 10, the interlocking members 70 couples the first coupling member 41 and the second coupling member 42. Thus, a force applied to one of the first coupling member 41 and the second coupling member 42 is directly transmitted to the other of the first coupling member 41 and the second coupling member 42. This limits the force directed from the first coupling member 41 and the second coupling member 42 toward the horizontal member 12.

[0073] Furthermore, each interlocking member 70 is formed from steel. Thus, the interlocking member 70 resists deformation even if one of the first coupling member 41 and the second coupling member 42 applies force to the interlocking member 70. This allows the interlocking member 70 to transmit the force applied to one of the first coupling member 41 and the second coupling member 42 to the other one of the first coupling member 41 and the second coupling member 42 in a preferable manner. 2025223837   07 Aug 2026

[0074] The third operation of the present embodiment will now be described. The interlocking member 70 is arranged inside the horizontal member 12. Thus, the interlocking member 70 is concealed inside the horizontal member 12. This allows the horizontal member 12 to be formed as a visible beam.

[0075] The fourth operation of the present embodiment will now be described. The interlocking members 70 are arranged inside the horizontal member 12. Thus, the interlocking members 70 may be arranged inside the horizontal member 12 when manufacturing the horizontal member 12. The interlocking members 70 do not have to be arranged in the holes 18 of the horizontal member 12 when constructing the wall 10 at a construction site.

[0076] Advantages of Embodiments The advantages of the present embodiments will now be described. (1) The building wall 10 includes the horizontal member 12, the first structural panel 21 arranged above the horizontal member 12, the second structural panel 22 arranged above the horizontal member 12 adjacent to the first structural panel 21, and the first coupling member 41 coupling the first structural panel 21 and the second structural panel 22 to the horizontal member 12. The first structural panel 21 and the second structural panel 22 are coupled to the horizontal member 12 by the first coupling member 41 without contacting the horizontal member 12. The first coupling member 41 includes the first part 41A located between the horizontal member 12 and the first structural panel 21 to couple the first structural panel 21 to the horizontal member 12, and the second part 41B located between the horizontal member 12 and the second structural panel 22 to couple the second structural panel 22 to the horizontal member 12. At least a portion of the second part 41B is formed integrally with the first part 41A. 2025223837   07 Aug 2026

[0077] The shear force generated when the structural panels 20 are rotated is an example of the force applied to the horizontal member 12 when the building 1 sways. More specifically, when the building 1 sways, the structural panels 20 oscillate in substantially the same cycle. In other words, when the building 1 sways, the first structural panel 21 and the second structural panel 22 are rotated in the same direction. In one example, in the proximity of the horizontal member 12, a lower edge of the first structural panel 21 located toward the second structural panel 22 is moved upward and a lower edge of the second structural panel 22 located toward the first structural panel 21 is moved downward. This generates shear force acting on the part of the horizontal member 12 that receives force from two edges, namely, the lower edge of the first structural panel 21 located toward the second structural panel 22 and the lower edge of the second structural panel 22 located toward the first structural panel 21.

[0078] In this regard, in the above structure, at least a portion of the second part 41B is formed integrally with the first part 41A. Thus, the portion where the first part 41A is integrated with the second part 41B receives the force acting in the upward direction applied by the edge of the first structural panel 21 and the force acting in the downward direction applied by the edge of the second structural panel 22. This limits the shear force applied to the horizontal member 12. Since the first coupling member 41 limits the shear force acting on the horizontal member 12 at the portion between the first structural panel 21 and the second structural panel 22, deformation of the horizontal member 12 that would be caused by the shear force is limited.

[0079] (2) The wall 10 of the building 1 further includes the third structural panel 23 arranged below the horizontal member 12, the fourth structural panel 24 arranged below the horizontal member 12 adjacent to the third structural panel 23, and the second coupling member 42 coupling the third structural panel 23 and the fourth structural panel 24 to the horizontal member 12. The third structural panel 23 and the fourth structural panel 24 are 2025223837   07 Aug 2026 coupled to the horizontal member 12 by the second coupling member 42 without contacting the horizontal member 12. The second coupling member 42 includes the third part 42A located between the horizontal member 12 and the third structural panel 23 to couple the third structural panel 23 to the horizontal member 12, and the fourth part 42B located between the horizontal member 12 and the fourth structural panel 24 to couple the fourth structural panel 24 to the horizontal member 12. At least a portion of the fourth part 42B is formed integrally with the third part 42A. The middle line C2 located between the third structural panel 23 and the fourth structural panel 24 coincides with the middle line C1 located between the first structural panel 21 and the second structural panel 22.

[0080] When the building 1 sways, the third structural panel 23 and the fourth structural panel 24 are rotated in the same direction. In one example, in the proximity of the horizontal member 12, an upper edge of the third structural panel 23 located toward the fourth structural panel 24 is moved upward and an upper edge of the fourth structural panel 24 located toward the third structural panel 23 is moved downward. This generates shear force acting on the part of the horizontal member 12 that receives force from two edges, namely, the upper edge of the third structural panel 23 located toward the fourth structural panel 24, and the upper edge of the fourth structural panel 24 located toward the third structural panel 23.

[0081] In this regard, in the above structure, at least a portion of the fourth part 42B is formed integrally with the third part 42A. Thus, the portion where the third part 42A is integrated with the fourth part 42B receives the force acting in the upward direction applied by the edge of the third structural panel 23 and the force acting in the downward direction applied by the edge of the fourth structural panel 24. This limits the shear force applied to the horizontal member 12. Since the second coupling member 42 limits the shear force acting on the horizontal member 12 at the portion between the third structural panel 23 and the fourth 2025223837   07 Aug 2026 structural panel 24, deformation of the horizontal member 12 that would be caused by the shear force is limited.

[0082] (3) The first coupling member 41 is interlocked with the second coupling member 42 by the interlocking members 70 arranged inside the horizontal member 12. With this structure, the first coupling member 41 is coupled to the second coupling member 42 by the interlocking members 70. Thus, the force generated by the rotation of the structural panels 20 arranged above the horizontal member 12 is transmitted to the structural panels 20 arranged below the horizontal member 12 through the interlocking members 70. Therefore, the interlocking members 70 limit the stress applied to the horizontal member 12 by the forces generated by the rotation of the structural panels 20 arranged above the horizontal member 12. This also limits deformation of the horizontal member 12 caused by the force generated when the structural panels 20 arranged above the horizontal member 12 are rotated.

[0083] Further, “the force generated by the rotation of the structural panels 20 arranged above the horizontal member 12” refers to the force applied to the horizontal member 12 by the edges of the structural panels 20 when the structural panels 20 are rotated. Here, “the force applied to the horizontal member 12 by the edges” includes the pushing force and the pulling force applied by the structural panels 20 to the horizontal member 12.

[0084] (4) The first structural panel 21, the second structural panel 22, the third structural panel 23, and the fourth structural panel 24 each have the panel fastening portion 32. The first coupling member 41 and the second coupling member 42 each have the coupling fastening portion 54. The panel fastening portion 32 of the first structural panel 21 and the panel fastening portion 32 of the second structural panel 22 are each connected to the coupling fastening portion 54 of the first coupling member 41 by the first connecting member 60X. The panel fastening portion 32 of the third structural panel 23 and the panel fastening portion 32 of 2025223837   07 Aug 2026 the fourth structural panel 24 are each connected to the coupling fastening portion 54 of the second coupling member 42 by the second connecting member 60Y differing from the first connecting member 60X.

[0085] With this structure, the first connecting members 60X connect the first structural panel 21 and the second structural panel 22 to the first coupling member 41. Further, the second connecting members 60Y connect the third structural panel 23 and the fourth structural panel 24 to the second coupling member 42.

[0086] (5) The first coupling member 41 includes the first plate 43 that includes a portion of the first part 41A and a portion of the second part 41B and the first bracket 44 that includes the coupling fastening portion 54. The first plate 43 is fixed to the upper surface 12A of the horizontal member 12. The first bracket 44 extends upward from the first plate 43. The second coupling member 42 includes the second plate 45 that includes a portion of the third part 42A and a portion of the fourth part 42B and the second bracket 46 that includes the coupling fastening portion 54. The second plate 45 is fixed to the lower surface 12B of the horizontal member 12. The second bracket 46 extends downward from the second plate 45.

[0087] With this structure, in the first coupling member 41, the first bracket 44 is fixed to the first plate 43 and extends upward from the first plate 43. Thus, the first coupling member 41 has a T-shaped cross-section. This improves the durability of the first coupling member 41 with respect to the force applied by the structural panels 20 arranged above the horizontal member 12. In the same manner, the second bracket 46 is fixed to the second plate 45 and extends downward from the second plate 45. Thus, the second coupling member 42 has a T-shaped cross-section. This improves the durability of the second coupling member 42 with respect to the forces applied by the structural panels 20 arranged below the horizontal member 12. 2025223837   07 Aug 2026

[0088] (6) The building 1 includes the wall 10 of the building 1. This structure allows for the formation of a wall that resists deformation even though the structural panels 20 are coupled to the horizontal member 12. Thus, the durability of the building 1 is improved.

[0089] Modifications The above embodiment exemplifies structures of the building 1 and the wall 10 of the building 1 and is not intended to impose any limitation. The building 1 and the wall 10 of the building 1 may differ from the structures exemplified in the above embodiment. Parts of the structures described in the embodiment may be replaced, changed, or omitted. Otherwise, a new feature may be added to the structure of the embodiment. Modifications of the embodiment will now be described.

[0090] The first coupling member 41 or the second coupling member 42 may be omitted from the wall 10. In this modification, the wall 10 is formed as a single-layer load-bearing wall. Even if the structural panel 20 is a single-layer, the coupling member 50, which couples the structural panel 20 to the horizontal member 12, limits deformation of the horizontal member 12.

[0091] The middle line C2, located between the third structural panel 23 and the fourth structural panel 24, may be separated from the middle line C1, located between the first structural panel 21 and the second structural panel 22.

[0092] The interlocking members 70 may be omitted from the wall 10. In this modification, the coupling member 50 may be directly fixed to the horizontal member 12. In the present embodiment, the first plate 43 of the first part 41A is formed integrally with the first plate 43 of the second part 41B in the first coupling member 41. However, a portion of the second part 41B may be formed integrally with the first part 41A in a different 2025223837   07 Aug 2026 manner. For example, the first part 41A and the second part 41B may be connected with a rodshaped component. The same applies to the second coupling member 42.

[0093] In the coupling member 50, the brackets 52 may be arranged separately from the plate 51. For example, the brackets 52 may be attached in a removable manner to the plate 51 by the fastening members 80.

[0094] In the present embodiment, the first structural panel 21 and the second structural panel 22 are adjacent to each other above the horizontal member 12. However, three or more structural panels 20 may be arranged above the horizontal member 12. In the same manner, three or more structural panels 20 may be arranged below the horizontal member 12.

[0095] The wall 10 extends from the first floor to the second floor of the building 1. The wall 10 may also extend from the second floor or a higher floor to a further upper floor. The horizontal member 12 may be formed from steel. For example, the steel horizontal member 12 may be a wide flange beam.

[0096] The horizontal member 12 is not limited to a beam. The horizontal member 12 may be a floor material. For example, the floor material of the building 1 may use the same panels as the structural panels 20. The floor material of the building 1 as the horizontal member 12 may be structured from a parallel chord truss.

[0097] In this specification, the terms ‘comprises’, ‘comprising’, ‘includes’, ‘including’, or similar terms are intended to mean a non-exclusive inclusion, such that a method, system or apparatus that comprises a list of elements does not include those elements solely, but may well include other elements not listed.
