[0009] <Summary of Disclosure> This specification discloses the following partition walls and their installation structures. The reference numerals used in this summary of the disclosure are referenced in Figures 1 to 5. These reference numerals are used to facilitate understanding of the partition walls and their installation structures, and the scope of the invention is not limited to the examples shown in the drawings.

[0010] One aspect of the present disclosure is, firstly, a partition wall 10 (10A to 10D) in which a plurality of facing materials 30, 130, 230 are attached to both sides or one side of a frame-shaped partition wall body 20 (20A to 20D), as shown in Figures 1 to 5, The aforementioned partition wall body 20 (20A~20D) is, A pair of vertical bars 21, 22 (22A, 22B), An upper horizontal bar 23 is provided, which is spanned between the upper ends of a pair of vertical bars 21, 22 (22A, 22B), A lower horizontal bar 24 is provided, which is spanned between the lower ends of a pair of vertical bars 21, 22 (22A, 22B), It comprises at least one intermediate crossbar 25(25A,25B), 26(26A,26B) which is provided spanning between a pair of vertical crossbars 21,22(22A,22B) and positioned between the upper crossbar 23 and the lower crossbar 24, The plurality of the aforementioned facing materials 30, 130, 230 are arranged with gaps 40, 140, 240 between them in the width direction, height direction, or both of the partition wall body 20 (20A to 20D).

[0011] According to this, the frame formed on the frame by a pair of vertical bars 21, 22 (22A, 22B), an upper horizontal bar 23, and a lower horizontal bar 24 is reinforced by intermediate horizontal bars 25 (25A, 25B) and 26 (26A, 26B), thereby improving the rigidity of the partition wall body 20 (20A~20D). Furthermore, since such a partition wall body 20 (20A~20D) is reinforced by multiple facing materials 30 (30A~30D, etc.), 130 (130A~130H, etc.), and 230 (230A, 230B), the rigidity of the partition wall 10 (10A~10D) can be improved, thereby increasing seismic resistance. Furthermore, since the face material gaps 40, 140, and 240 are formed, work inside the partition wall 10 (10A to 10D) can be carried out without removing the face materials 30, 130, and 230. This not only makes wiring and piping work easier but also makes the installation and removal work of the partition wall 10 (10A to 10D) itself easier, facilitating renovation. Moreover, the partition wall body 20 (20A to 20D) can be formed with a small number of parts, and the face materials 30, 130, and 230 can use materials (edge materials) with a small area that were difficult to utilize effectively before. Therefore, the manufacturing cost of the partition wall 10 (10A to 10D) can be reduced, and as a result, it becomes possible to provide the partition wall 10 (10A to 10D) at a low cost.

[0012] Second, as shown in FIGS. 1 and 2 for example, in the partition wall body 20 (20A) to which a plurality of the face materials 30, 130 are fixed on both sides, the plurality of the face materials 30, 130 include one of the face materials 30, 130 fixed to one side surface of the partition wall body 20 (20A), and the other of the face materials 30, 130 fixed to the other side surface of the partition wall body 20 (20A), at least one or more of the intermediate horizontal bars 25 (25A, 25B), 26 (26A, 26B) include one of the intermediate horizontal bars 25A, 26A to which one of the face materials 30, 130 is fixed, and the other of the intermediate horizontal bars 25B, 26B to which the other of the face materials 30, 130 is fixed, and gaps 27, 28 are formed between one of the intermediate horizontal bars 25A, 26A and the other of the intermediate horizontal bars 25B, 26B.

[0013] According to this, the facing materials 30, 130 and the intermediate horizontal bars 25(25A, 25B), 26(26A, 26B) are attached to both sides of the partition wall body 20(20A). In addition, the gaps 27, 28 are formed inside the partition wall body 20(20A). Therefore, it is possible to provide a partition wall 10(10A) in which the facing materials 30, 130 and the intermediate horizontal bars 25(25A, 25B), 26(26A, 26B) enhance the seismic resistance of the partition wall 10(10A) while the intermediate horizontal bars 25(25A, 25B), 26(26A, 26B) do not obstruct wiring or piping. In particular, compared to the case where multiple facing materials 30,130 are attached to only one side of the partition wall body 20 (20A), for example, the rigidity of the partition wall 10 (10A) can be significantly improved, resulting in superior seismic resistance.

[0014] Thirdly, in a partition wall body 20 (20B to 20D) to which multiple facing materials 30, 130, 230 are attached to one side, as shown in Figures 3 to 5, Multiple of the aforementioned facing materials 30, 130, 230 are fastened to one side of the partition wall body 20 (20B~20D). At least one of the intermediate crossbars 25(25A, 25B), 26(26A, 26B) is composed of one of the intermediate crossbars 25A, 26A to which the facing material 30, 130, 230 on one side is fastened. The other side is characterized by the absence of the intermediate crossbars 25B and 26B.

[0015] According to this, the intermediate horizontal bars 25A, 26A and the facing materials 30, 130, 230 are attached to only one side of the partition wall body 20 (20B~20D), leaving a large space on the other side for routing wiring and piping. Therefore, while the seismic resistance of the partition wall 10 (10B~10D) is enhanced by the facing materials 30, 130, 230 and the intermediate horizontal bars 25A, 26A, wiring and piping can be arranged more freely. Moreover, compared to, for example, the case where multiple facing materials 30, 130, 230 are attached to both sides of the partition wall body 20 (20B~20D), the installation and removal of the partition wall 10 (10B~10D) becomes easier, thus facilitating renovations.

[0016] Fourth, for example, as shown in Figures 2, 3, and 5, when multiple surface materials 130, 230 are arranged with spacing in the height direction, At least one of the intermediate crossbars 25(25A,25B), 26(26A,26B) has: The upper intermediate crossbar 25 (25A, 25B) is positioned at the same height as the lower end of the upper surface material 130 (130A, 130B, etc.) 230 (230A), The lower intermediate crossbar 26 (26A, 26B) is positioned at the same height as the upper end of the lower surface material 130 (130C, 130D, etc.), 230 (230B), It is characterized by including this.

[0017] According to this, at least one of the intermediate crossbars 25(25A, 25B), 26(26A, 26B) includes an upper intermediate crossbar 25(25A, 25B) positioned at the same height as the lower end of the upper surface material 130(130A, 130B, etc.), 230(230A). Therefore, the lower end of the upper surface material 130(130A, 130B, etc.), 230(230A) can be securely attached to the upper intermediate crossbar 25(25A, 25B). Furthermore, since the lower intermediate horizontal bars 26 (26A, 26B) are positioned at the same height as the upper ends of the lower surface materials 130 (130C, 130D, etc.) and 230 (230B), the upper ends of the lower surface materials 130 (130C, 130D, etc.) and 230 (230B) can be securely attached to the lower intermediate horizontal bars 26 (26A, 26B). As a result, the surface materials 130 and 230 are less likely to be damaged or peel off from the partition wall body 20 (20A, 20B, 20D), thus protecting the structure necessary for ensuring seismic resistance. Furthermore, the lower ends of the upper facing materials 130 (130A, 130B, etc.) and 230 (230A) are attached to the upper intermediate crossbars 25 (25A, 25B) which are positioned at the same height as the lower ends of the facing materials 130 (130A, 130B, etc.) and 230 (230A), and the upper ends of the lower facing materials 130 (130C, 130D, etc.) and 230 (230B) are attached to the upper intermediate crossbars 25 (25A, 25B) which are positioned at the same height as the lower ends of the facing materials 130 (130C, 130D, etc.) and 230 (230 Since it is attached to the lower intermediate crossbar 26 (26A, 26B) which is positioned at the same height as the upper end of B), the lower ends of the upper facing materials 130 (130A, 130B, etc.) and 230 (230A) can be prevented from protruding downwards more than necessary, and the upper ends of the lower facing materials 130 (130C, 130D, etc.) and 230 (230B) can be prevented from protruding upwards more than necessary. As a result, the spacing between the facing materials 130 and 230 which are spaced apart in the height direction can be kept wide, so that, for example, a space for performing work such as wiring and piping can be secured as wide as possible not only in the height direction but also in the width direction at the height center of the partition wall 10 (10A, 10B, 10D).

[0018] Fifthly, an installation structure for a partition wall, characterized in that, for example as shown in Figures 1 to 5, the partition wall body 20 (20A to 20D) is arranged perpendicular to the outer wall 50 in a plan view, and of the pair of vertical bars 21 and 22 (22A, 22B), the vertical bar 21 on the outer wall 50 side is fixed to the outer wall 50 with a fastener, and the lower horizontal bar 24 is fixed to the floor with a fastener.

[0019] According to this, the partition wall body 20 (20A to 20D) is fixed perpendicularly to the outer wall 50 by fasteners 70. The partition wall body 20 (20A to 20D) is also fixed to the floor by fasteners 70. Therefore, while the seismic resistance of the partition wall 10 (10A to 10D) is enhanced by fixing it to the outer wall 50, the partition wall 10 (10A to 10D) can be easily removed by removing the fasteners.

[0020] Sixth, as shown in Figures 3 to 5, for example, one of the vertical battens 21 located on the side of the outer wall 50 and the other vertical batten 22 (22B) located on the opposite side are characterized in that they are erected in orientations that are 90 degrees different in plan view.

[0021] According to this, the vertical battens 21 have a wide surface area that is fixed to the wall, while a space is created behind the vertical battens 22 (22B). Therefore, it is possible to further secure space for wiring and piping while increasing seismic resistance.

[0022] Furthermore, in recent years, there has been a growing demand for the realization of a decarbonized society through the promotion of carbon neutrality, which aims to reduce carbon dioxide emissions to virtually zero, and for the achievement of the Sustainable Development Goals (SDGs). In the construction industry, efforts are also being made to use wood in buildings, which has lower carbon dioxide emissions. The partition wall according to one aspect of this disclosure can utilize small materials that were previously difficult to use effectively as the surface materials 30, 130, and 230, and thus can contribute to the realization of a decarbonized society through the promotion of carbon neutrality and the achievement of the SDGs.

[0023] Other specific details will be clarified in the following explanation.

[0024] <Embodiment> Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments described below are subject to various technically preferred limitations for carrying out the present invention, but the technical scope of the present invention is not limited to the embodiments and illustrated examples below. Note that the directions and orientations in the embodiments and illustrated examples below are set solely for the convenience of explanation.

[0025] The building in this embodiment is constructed using a panel construction method in which building components such as walls, floors, and roofs are pre-fabricated into panels in a factory, and these panels (hereinafter referred to as building wood panels) are assembled at the construction site. However, it may also be a conventional post-and-beam construction method, a wall-type construction method, or a wooden, steel-frame, or reinforced concrete building. Furthermore, the building may be multi-story or single-story.

[0026] In architectural wood panels, vertical and horizontal frame members are assembled in a rectangular shape, and auxiliary cross members are assembled vertically and horizontally inside the rectangular frame to form a frame body. Plywood or other facing material is attached to both sides or one side of this frame body, resulting in a hollow internal structure. Furthermore, insulation materials such as glass wool or rock wool, or foamed plastic insulation materials are appropriately selected and installed in the hollow internal portion.

[0027] The building in this embodiment is a two-story building, and an exterior wall 50 is provided along the outer perimeter of the building. This exterior wall 50 is composed of an exterior wall 52 for the first floor, an exterior wall 51 for the second floor, a part of the floor for the first floor, and a part of the floor for the second floor. The exterior wall 52 for the first floor is made of building wood panels for exterior walls (hereinafter referred to as the first-floor exterior wall panel 52).

[0028] The floor of the second floor is made of building wood panels for flooring (hereinafter referred to as the second-floor floor panel 90). The second-floor floor panel 90 comprises a second-floor floor panel surface material 91 and a frame material 92. The second-floor floor panel 90 is supported by the first-floor exterior wall panel 52.

[0029] An exterior wall 51 is provided along the outer perimeter of the second floor. This exterior wall 51 is made of building panels for exterior walls (hereinafter referred to as the second-floor exterior wall panel 51). The second-floor exterior wall panel 51 stands on a frame 92 and a girder 60.

[0030] <First Embodiment> Figure 1 shows a partition wall 10 according to the first embodiment of the present invention. Figure 1(a) is a front view of the partition wall 10, and Figure 1(b) is a side cross-sectional view of the partition wall 10. The partition wall 10 is a structure that divides the interior space into multiple rooms. The living space is divided by the partition wall 10 alone, or by arranging multiple partition walls 10 together with adjacent partition walls 80 in a row. The adjacent partition walls 80 are set to the same height and thickness as the partition wall 10.

[0031] This partition wall 10 is installed on the second-floor floor panel 90 so as to be perpendicular to the second-floor exterior wall panel 51 in a plan view. Note that the partition wall 10 is not limited to the second floor; it may also be installed on the first floor. If the building in this embodiment is three stories or more, it may also be installed on the third floor or higher.

[0032] The partition wall 10 is composed of a rectangular partition wall body 20 and a plurality of facing materials 30 attached to both sides of the partition wall body 20. In this embodiment, four facing materials 30 are used.

[0033] The partition wall body 20 comprises a first vertical rail 21, a second vertical rail 22A, an upper horizontal rail 23, a lower horizontal rail 24, and two first intermediate horizontal rails 25A and 25B.

[0034] The first vertical batten 21 extends vertically and is installed adjacent to the second-floor exterior wall panel 51. The second vertical batten 22A extends vertically and is installed adjacent to the adjacent partition wall 80. The first vertical batten 21 and the second vertical batten 22A are installed in the same orientation in a plan view.

[0035] The upper horizontal bar 23 is installed by spanning between the upper ends of the first vertical bar 21 and the second vertical bar 22A. The upper horizontal bar 23 is positioned on the winning side in relation to the first vertical bar 21 and the second vertical bar 22A. That is, the upper horizontal bar 23 is installed by spanning between the upper end faces of the first vertical bar 21 and the second vertical bar 22A. When the partition wall 10 is manufactured in the factory, the upper horizontal bar 23 is fixed to the first vertical bar 21 and the second vertical bar 22A by screwing the upper horizontal bar 23 towards the first vertical bar 21 and the second vertical bar 22A. In this embodiment, however, the first vertical bar 21 and the second vertical bar 22A may be positioned on the winning side of the upper horizontal bar 23.

[0036] The lower horizontal bar 24 is installed by spanning between the lower ends of the first vertical bar 21 and the second vertical bar 22A. The lower horizontal bar 24 is positioned on the winning side in relation to the first vertical bar 21 and the second vertical bar 22A. That is, the first vertical bar 21 and the second vertical bar 22A are provided on the upper surfaces of both ends of the lower horizontal bar 24 in the longitudinal direction. When the partition wall 10 is manufactured in the factory, the lower horizontal bar 24 is fixed to the first vertical bar 21 and the second vertical bar 22A by screwing them from the lower horizontal bar 24 toward the first vertical bar 21 and the second vertical bar 22A. In this embodiment, however, the first vertical bar 21 and the second vertical bar 22A may be positioned on the winning side of the lower horizontal bar 24.

[0037] The two first intermediate horizontal bars 25A and 25B are installed by spanning across the first vertical bar 21 and the second vertical bar 22A, which are located between the upper horizontal bar 23 and the lower horizontal bar 24. The two first intermediate horizontal bars 25A and 25B are spanned at the same height and are in contact with the front and back of the partition wall body 20, respectively. Furthermore, their height is above the vertical center of the partition wall body 20. In this embodiment, the two first intermediate horizontal bars 25A and 25B are positioned at the same height and face each other horizontally.

[0038] The combined length of the two first intermediate crossbars 25A and 25B in the depth direction is shorter than the depth direction of the partition wall body 20. Therefore, a first gap 27 is created between the two first intermediate crossbars 25A and 25B. Wiring and piping can be passed through the first gap 27.

[0039] The four facing panels 30 attached to the partition wall body 20 are rectangular structural plywood panels, all of the same size. The facing panels 30 include facing panels 30A and 30B that are attached to the front, and facing panels 30C and 30D that are attached to the back.

[0040] The length of the longer side of the panel 30 is the same as the height of the partition wall body 20. The length of the shorter side of the panel 30 is approximately one-third to one-quarter the length of the partition wall body 20. The panel 30 is fixed to the partition wall body 20, and screws may also be used for this purpose.

[0041] The facing material 30A is positioned on the front of the partition wall body 20, towards the first vertical rail 21, so that one of its upper and lower corners aligns with one of the upper and lower corners on the front of the partition wall body 20. The facing material 30A is attached to the first vertical rail 21, the upper horizontal rail 23, and the first intermediate horizontal rail 25A on the front side.

[0042] The facing material 30B is positioned on the front of the partition wall body 20, towards the second vertical rail 22A, so that one of its upper and lower corners aligns with one of the upper and lower corners on the front of the partition wall body 20. The facing material 30B is attached to the second vertical rail 22A, the upper horizontal rail 23, and the first intermediate horizontal rail 25A on the front side.

[0043] The facing material 30C is positioned on the back side of the partition wall body 20, towards the first vertical rail 21, so that one of its upper and lower corners aligns with one of the upper and lower corners on the back side of the partition wall body 20. The facing material 30C is attached to the first vertical rail 21, the upper horizontal rail 23, and the first intermediate horizontal rail 25A on the back side.

[0044] The facing material 30D is positioned on the back side of the partition wall body 20, towards the second vertical rail 22A, so that one of its upper and lower corners aligns with one of the upper and lower corners on the back side of the partition wall body 20. The facing material 30D is attached to the second vertical rail 22A, the upper horizontal rail 23, and the first intermediate horizontal rail 25A on the back side.

[0045] The panels 30 installed in this manner form a gap 40 between panels in the center of the width direction of the partition wall 10. The vertical length of the gap 40 is the same as the height of the partition wall 10. The width of the gap 40 is approximately one-third to half of the width dimension of the partition wall 10.

[0046] The partition wall 10 is fixed to the second-floor exterior wall panel 51 by driving screws 70 from the first vertical batten 21 toward the second-floor exterior wall panel 51. The partition wall 10 is also fixed to the second-floor floor panel 90 by driving screws 70 from the lower horizontal batten 24 toward the second-floor floor panel 90. Note that the fasteners are not limited to screws 70; bolts or nails may also be used.

[0047] As described above, gypsum board is attached to the front and back of the partition wall 10 fixed adjacent to the second-floor exterior wall panel 51, although this is not shown in the diagram, and a finishing material is then applied on top of it.

[0048] The partition wall 10 formed in this manner in the first embodiment is expected to have the following effects.

[0049] First, the frame formed on the frame by the first vertical support 21, the second vertical support 22A, the upper horizontal support 23, and the lower horizontal support 24 is reinforced by the first intermediate horizontal support 25A, 25B and the second intermediate horizontal support 26A, 26B, thereby improving the rigidity of the partition wall body 20. Furthermore, since the partition wall body 20 is reinforced by multiple facing materials 30, the rigidity of the partition wall 10 can be improved, thereby increasing its seismic resistance.

[0050] Next, the formation of gaps 40 between the facing materials allows work to be performed inside the partition wall 10 without removing the facing materials 30, making wiring and piping work easier, as well as making it easier to install and remove the partition wall 10 itself, thus facilitating renovations.

[0051] Furthermore, the partition wall body 20 can be formed with a small number of parts, and the facing material 30 can use structural plywood with a small surface area that was previously difficult to utilize effectively. As a result, the manufacturing cost of the partition wall 10 can be reduced, making it possible to provide the partition wall 10 at a low cost.

[0052] Furthermore, since the facing material 30 covers only a portion of the partition wall body 20, it becomes possible to use small structural plywood pieces that were previously difficult to utilize effectively. As a result, waste can be reduced, which can contribute to the realization of a decarbonized society through the promotion of carbon neutrality and the achievement of the SDGs.

[0053] <Second Embodiment> The second embodiment will be described below. In the second and subsequent embodiments, unless otherwise specified, the same components as in the first embodiment will be omitted or simplified in their description.

[0054] Figure 2 shows a partition wall 10A according to a second embodiment of the present invention. Figure 2(a) is a front view of partition wall 10A, and Figure 2(b) is a side cross-sectional view of partition wall 10A.

[0055] The partition wall 10A is composed of a rectangular partition wall body 20A and a plurality of facing materials 130 attached to both sides of the partition wall body 20A. In this embodiment, eight facing materials 130 are used.

[0056] In the second embodiment, two first intermediate crossbars 25A, 25B and two second intermediate crossbars 26A, 26B are provided spanning between the first vertical bar 21 and the second vertical bar 22A.

[0057] The two first intermediate horizontal bars 25A and 25B are provided at a height above the vertical center of the partition wall body 20A, similar to the first embodiment described above. On the other hand, the two second intermediate horizontal bars 26A and 26B are provided at a height below the vertical center of the partition wall body 20A.

[0058] Furthermore, the distance between the two first intermediate crossbars 25A and 25B and the upper crossbar 23, and the distance between the two second intermediate crossbars 26A and 26B and the lower crossbar 24 are set to approximately equal dimensions.

[0059] The second intermediate crossbars 26A and 26B, like the first intermediate crossbars 25A and 25B, are installed at the same height and are in contact with the front and back of the partition wall body 20A, respectively. The combined length of the two second intermediate crossbars 26A and 26B in the depth direction is shorter than the length of the partition wall body 20A in the depth direction. As a result, a second gap 28 is created between the two second intermediate crossbars 26A and 26B. Wiring and piping can be passed through the second gap 28.

[0060] The eight facing panels 130 attached to the partition wall body 20A are rectangular structural plywood panels, all of the same size. The facing panels 130 include facing panels 130A, 130B, 130C, and 130D that are attached to the front of the partition wall body 20A, and facing panels 130E, 130F, 130G, and 130H that are attached to the back of the partition wall body 20A.

[0061] The longer side of the panel 130 is approximately equal to the length from the height of the lower end of the first intermediate horizontal bars 25A and 25B to the height of the upper end of the upper horizontal bar 23. The shorter side of the panel 130 is approximately one-third to one-quarter the length of the partition wall body 20A. In other words, the lengths of the longer and shorter sides of the panel 130A, 130B, 130C, 130D, 130E, 130F, 130G, and 130H are all dimensionally set as described above.

[0062] The facing material 130A is positioned on the front of the partition wall body 20A, close to the corner formed by the first vertical rail 21 and the upper horizontal rail 23, with its upper end attached to the upper horizontal rail 23, its lower end attached to the first intermediate horizontal rail 25A and the first vertical rail 21, and one side end attached to the first vertical rail 21.

[0063] The facing material 130B is positioned on the front of the partition wall body 20A, close to the corner formed by the second vertical rail 22A and the upper horizontal rail 23, with its upper end attached to the upper horizontal rail 23, its lower end attached to the first intermediate horizontal rail 25A and the second vertical rail 22A, and one side end attached to the second vertical rail 22A.

[0064] The facing material 130C is positioned on the front of the partition wall body 20A, close to the corner formed by the first vertical rail 21 and the lower horizontal rail 24, with its upper end attached to the second intermediate horizontal rail 26A and the first vertical rail 21, its lower end attached to the lower horizontal rail 24, and one side end attached to the first vertical rail 21.

[0065] The facing material 130D is positioned on the front of the partition wall body 20A, close to the corner formed by the second vertical rail 22A and the lower horizontal rail 24, with its upper end attached to the second intermediate horizontal rail 26A and the second vertical rail 22A, its lower end attached to the lower horizontal rail 24, and one side end attached to the second vertical rail 22A.

[0066] The facing material 130E is positioned on the back of the partition wall body 20A, near the corner formed by the first vertical rail 21 and the upper horizontal rail 23, with its upper end attached to the upper horizontal rail 23, its lower end attached to the first intermediate horizontal rail 25B and the first vertical rail 21, and one side end attached to the first vertical rail 21.

[0067] The facing material 130F is positioned on the back of the partition wall body 20A, near the corner formed by the second vertical rail 22A and the upper horizontal rail 23, with its upper end attached to the upper horizontal rail 23, its lower end attached to the first intermediate horizontal rail 25A and the second vertical rail 22B, and one side end attached to the second vertical rail 22A.

[0068] The facing material 130G is positioned on the back of the partition wall body 20A, near the corner formed by the first vertical rail 21 and the lower horizontal rail 24, with its upper end attached to the second intermediate horizontal rail 26B and the first vertical rail 21, its lower end attached to the lower horizontal rail 24, and one side end attached to the first vertical rail 21.

[0069] The facing material 130H is positioned on the back of the partition wall body 20A, close to the corner formed by the second vertical rail 22A and the lower horizontal rail 24, with its upper end attached to the second intermediate horizontal rail 26B and the second vertical rail 22A, its lower end attached to the lower horizontal rail 24, and one side end attached to the second vertical rail 22A.

[0070] The facing material 130 installed in this manner forms a cross-shaped gap 140 between the facing materials in the partition wall 10A. That is, no facing material 130 is installed between the first intermediate horizontal bars 25A, 25B and the second intermediate horizontal bars 26A, 26B. In addition, facing material 130 is installed between the upper horizontal bar 23 and the first intermediate horizontal bars 25A, 25B, and between the lower horizontal bar 24 and the second intermediate horizontal bars 26A, 26B, leaving a gap in the center in the width direction.

[0071] In the sections where the facing material 130 is installed, the vertical length of the gap 140 between the facing materials is the same as the length between the first intermediate horizontal bars 25A, 25B and the second intermediate horizontal bars 26A, 26B. In the sections where the facing material 130 is not installed, the vertical length of the gap 140 between the facing materials is the same as the height of the partition wall 10A.

[0072] In areas where the facing material 130 is installed, the width of the gap 140 between the facing materials is approximately one-third to half of the width dimension of the partition wall 10A. In areas where the facing material 130 is not installed, the width of the gap 140 between the facing materials is the same as the width dimension of the partition wall 10A.

[0073] Similar to the first embodiment, the second embodiment also reduces manufacturing costs by using fewer parts and small structural plywood that was previously difficult to use. On the other hand, since the partition wall 10A is reinforced with multiple facing materials and battens, it is possible to realize a partition wall 10A with excellent seismic resistance. In addition, the gap 140 between the facing materials makes wiring and piping work, as well as the installation and removal of the partition wall 10A, easier, thus reducing the effort required for renovations.

[0074] In addition, according to this embodiment, the first intermediate crossbars 25A and 25B include first intermediate crossbars 25A and 25B that are positioned at the same height as the lower ends of the upper facing materials 130A, 130B, 130E, and 130F, so that the lower ends of the upper facing materials 130A, 130B, 130E, and 130F can be securely attached to the first intermediate crossbars 25A and 25B. Furthermore, the second intermediate crossbars 26A and 26B include second intermediate crossbars 26A and 26B that are positioned at the same height as the upper ends of the lower facing materials 130C, 130D, 130G, and 130H, so that the upper ends of the lower facing materials 130C, 130D, 130G, and 130H can be securely attached to the second intermediate crossbars 26A and 26B.

[0075] Therefore, the facing material 130 is less prone to damage and peeling from the partition wall body 20A, thus protecting the structure necessary for ensuring earthquake resistance.

[0076] Furthermore, the lower ends of the upper panels 130A, 130B, 130E, and 130F are attached to the first intermediate crossbars 25A and 25B, which are positioned at the same height as the lower ends of the panels 130A, 130B, 130E, and 130F. Also, the upper ends of the lower panels 130C, 130D, 130G, and 130H are attached to the second intermediate crossbars 26A and 26B, which are positioned at the same height as the upper ends of the panels 130C, 130D, 130G, and 130H.

[0077] Therefore, the lower ends of the upper surface materials 130A, 130B, 130E, and 130F are prevented from protruding downwards more than necessary, and the upper ends of the lower surface materials 130C, 130D, 130G, and 130H are prevented from protruding upwards more than necessary.

[0078] Therefore, since the spacing between the surface materials 130, which are arranged with gaps in the height direction, can be kept wide, a space for tasks such as wiring and piping can be secured as wide as possible not only in the height direction but also in the width direction at the center of the partition wall 10A in the height direction.

[0079] Furthermore, since the dimensions of the facing material 130 differ from those of the facing material 30 in the first embodiment, structural plywood, which could not be used in the first embodiment, can also be used as the facing material 130.

[0080] <Third Embodiment> The third embodiment will be described below.

[0081] Figure 3 shows a partition wall 10B according to the third embodiment of the present invention. Figure 3(a) is a front view of partition wall 10B, Figure 3(b) is a side section view of partition wall 10B, and Figure 3(c) is a plan section view of partition wall 10B.

[0082] The partition wall 10B is composed of a rectangular partition wall body 20B and a plurality of facing materials 230 attached to one side of the partition wall body 20B. In this embodiment, two facing materials 230 are used.

[0083] In the third embodiment, a pair of vertical bars 21 and 22B constituting the partition wall body 20B are used: a first vertical bar 21 located on the second-floor exterior wall panel 51 side and a second vertical bar 22B located on the adjacent partition wall 80 side. These first vertical bar 21 and second vertical bar 22B are erected at angles that are 90 degrees apart in plan view.

[0084] Specifically, the first vertical bar 21 is erected with one wide side in contact with the second-floor exterior wall panel 51. The second vertical bar 22B is erected with one wide side facing forward in contact with the adjacent partition wall 80.

[0085] The first vertical beam 21 and the second vertical beam 22B are both rectangular timbers with a rectangular cross-section, and when installed vertically, their four sides include two wide sides and two narrow sides. In this embodiment, the vertical and horizontal dimensions of the cross-sections of the first vertical beam 21 and the second vertical beam 22B are set differently, but they may be set to be the same.

[0086] In the third embodiment, the first intermediate horizontal bar 25A and the second intermediate horizontal bar 26A are arranged to be in contact with the front of the partition wall body 20B. No intermediate horizontal bars or facing material 230 are placed on the back side of the partition wall body 20B, creating a space for passing wiring and piping.

[0087] The two facing panels 230 attached to the partition wall body 20B are rectangular structural plywood panels, both of the same size. The facing panels 230 include facing panels 230A and 230B, which are attached to the front of the partition wall body 20B.

[0088] The longer side of the panel 230 is equal to the length from the first intermediate horizontal bar 25A to the upper horizontal bar 23 and from the second intermediate horizontal bar 26A to the lower horizontal bar 24. The shorter side of the panel 230 is equal to the width of the partition wall body 20B.

[0089] The facing material 230A is attached to the first vertical rail 21, the second vertical rail 22B, the upper horizontal rail 23, and the first intermediate horizontal rail 25A on the front of the partition wall body 20B.

[0090] The facing material 230B is attached to the first vertical rail 21, the second vertical rail 22B, the lower horizontal rail 24, and the second intermediate horizontal rail 26A on the front of the partition wall body 20B.

[0091] Furthermore, the facing material 230 cannot be attached to the back of the partition wall body 20B. Therefore, wiring and piping can be routed through the back side of the partition wall body 20B.

[0092] The panel 230 installed in this manner forms a gap 240 between the panels at the center of the height direction on the front of the partition wall 10B. The vertical length of the gap 240 is the same as the length from the first intermediate horizontal bar 25A to the second intermediate horizontal bar 26A. The width of the gap 240 is the same as the width dimension of the partition wall 10B.

[0093] Similar to the first embodiment, the third embodiment reduces manufacturing costs by using fewer parts and small structural plywood that was previously difficult to utilize. On the other hand, since the partition wall 10B is reinforced with multiple facing materials and battens, it is possible to realize a partition wall 10B with excellent seismic resistance. In addition, the gap 240 between the facing materials makes wiring and piping work, as well as the installation and removal of the partition wall 10B, easier, thus reducing the effort required for renovations.

[0094] In addition, according to this embodiment, the first intermediate crossbar 25A includes a first intermediate crossbar 25A positioned at the same height as the lower end of the upper surface material 230A, so that the lower end of the upper surface material 230A can be securely attached to the first intermediate crossbar 25A. Furthermore, the second intermediate crossbar 26A includes a second intermediate crossbar 26A positioned at the same height as the upper end of the lower surface material 230B, so that the upper end of the lower surface material 230B can be securely attached to the second intermediate crossbar 26A.

[0095] Therefore, the facing material 230 is less prone to damage and peeling from the partition wall body 20B, thus protecting the structure necessary for ensuring earthquake resistance.

[0096] Furthermore, the lower end of the upper panel 230A is attached to the first intermediate crossbar 25A, which is positioned at the same height as the lower end of the panel 230A. Also, the upper end of the lower panel 230B is attached to the second intermediate crossbar 26A, which is positioned at the same height as the upper end of the panel 230B.

[0097] Therefore, the lower end of the upper surface material 230A does not protrude downward more than necessary, and the upper end of the lower surface material 230B does not protrude upward more than necessary.

[0098] Therefore, since the spacing between the surface materials 230, which are arranged with gaps in the height direction, can be kept wide, a space for tasks such as wiring and piping can be secured as wide as possible not only in the height direction but also in the width direction at the center of the partition wall 10B in the height direction.

[0099] Furthermore, unlike the first embodiment, there are no facing materials or intermediate horizontal bars on the back of the partition wall body 20B, making it possible to assemble wiring and piping more freely.

[0100] Furthermore, since the dimensions of the facing material 230 differ from those of the facing material 30 in the first embodiment, structural plywood, which could not be used in the first embodiment, can also be used as the facing material 230. In addition, since the facing material 230 is attached to only one side, less structural plywood is required compared to the first embodiment.

[0101] <Fourth Embodiment> The fourth embodiment will be described below.

[0102] Figure 4 shows a partition wall 10C according to the fourth embodiment of the present invention. Figure 4(a) is a front view of partition wall 10C, Figure 4(b) is a side section view of partition wall 10C, and Figure 4(c) is a top cross view of partition wall 10C.

[0103] The partition wall 10C is composed of a rectangular partition wall body 20C and a plurality of facing materials 30 attached to one side of the partition wall body 20C. In this embodiment, two facing materials 30 are used.

[0104] The vertical bars used in the fourth embodiment are the first vertical bar 21 and the second vertical bar 22B. The first intermediate horizontal bar 25A and the second intermediate horizontal bar 26A are arranged to be in contact with the front of the partition wall body 20C. No intermediate horizontal bars or facing material 30 are placed on the back side of the partition wall body 20C, creating a space for passing wiring and piping.

[0105] The facing material 30 includes facing materials 30A and 30B that are attached to the front of the partition wall body 20C. Both facing materials 30 have the same dimensions as in the first embodiment.

[0106] The facing material 30A is positioned on the front of the partition wall body 20C, towards the first vertical rail 21, so that one of its upper and lower corners aligns with one of the upper and lower corners on the front of the partition wall body 20C. The facing material 30A is attached to the first vertical rail 21, the upper horizontal rail 23, and the first intermediate horizontal rail 25A and second intermediate horizontal rail 26A on the front side.

[0107] The facing material 30B is positioned on the front of the partition wall body 20C, towards the second vertical rail 22A, so that one of its upper and lower corners aligns with one of the upper and lower corners on the front of the partition wall body 20C. The facing material 30B is attached to the second vertical rail 22A, the upper horizontal rail 23, and the first intermediate horizontal rail 25A and second intermediate horizontal rail 26A on the front side.

[0108] The panel material 30 installed in this manner forms a gap 40 between the panel material in the center of the width direction of the partition wall 10C. The vertical length of the gap 40 is the same as the height of the partition wall 10C. The width of the gap 40 is approximately one-third to half of the width dimension of the partition wall 10C.

[0109] Similar to the first embodiment, the fourth embodiment reduces manufacturing costs by using fewer parts and small structural plywood that was previously difficult to utilize. On the other hand, since the partition wall 10C is reinforced with multiple facing materials and battens, it is possible to realize a partition wall 10C with excellent seismic resistance. In addition, the gap 40 between the facing materials makes wiring and piping work, as well as the installation and removal of the partition wall 10C, easier, thus reducing the effort required for renovations.

[0110] Furthermore, unlike the first embodiment, there are no facing materials or intermediate horizontal bars on the back of the partition wall body 20C, making it possible to assemble wiring and piping more freely.

[0111] Furthermore, since the facing material 30 is attached to only one side, less structural plywood is required compared to the first embodiment.

[0112] <Fifth Embodiment> The fifth embodiment will be described below.

[0113] Figure 5 shows a partition wall 10D according to the fifth embodiment of the present invention. Figure 5(a) is a front view of partition wall 10D, and Figure 5(b) is a cross-sectional view of partition wall 10D.

[0114] The partition wall 10D is composed of a rectangular partition wall body 20D and a plurality of facing materials 130 attached to one side of the partition wall body 20D. In this embodiment, four facing materials 130 are used.

[0115] The vertical bars used in the fifth embodiment are the first vertical bar 21 and the second vertical bar 22B. The first intermediate horizontal bar 25A and the second intermediate horizontal bar 26A are arranged to be in contact with the front of the partition wall body 20D. No intermediate horizontal bars or face material 130 are placed on the back side of the partition wall body 20D, creating a space for passing wiring and piping.

[0116] The facing material 130 includes facing materials 130A, 130B, 130C, and 130D that are attached to the front of the partition wall body 20D. All of the facing materials 130 have the same dimensions as in the first embodiment.

[0117] The facing material 130A is positioned on the front of the partition wall body 20D, close to the corner formed by the first vertical rail 21 and the upper horizontal rail 23, with its upper end attached to the upper horizontal rail 23, its lower end attached to the first intermediate horizontal rail 25A and the first vertical rail 21, and one side end attached to the first vertical rail 21.

[0118] The facing material 130B is positioned on the front of the partition wall body 20D, close to the corner formed by the second vertical rail 22A and the upper horizontal rail 23, with its upper end attached to the upper horizontal rail 23, its lower end attached to the first intermediate horizontal rail 25A and the second vertical rail 22A, and one side end attached to the second vertical rail 22A.

[0119] The facing material 130C is positioned on the front of the partition wall body 20D, close to the corner formed by the first vertical rail 21 and the lower horizontal rail 24, with its upper end attached to the second intermediate horizontal rail 26A and the first vertical rail 21, its lower end attached to the lower horizontal rail 24, and one side end attached to the first vertical rail 21.

[0120] The facing material 130D is positioned on the front of the partition wall body 20D, close to the corner formed by the second vertical rail 22A and the lower horizontal rail 24, with its upper end attached to the second intermediate horizontal rail 26A and the second vertical rail 22A, its lower end attached to the lower horizontal rail 24, and one side end attached to the second vertical rail 22A.

[0121] The facing material 130 installed in this manner forms a cross-shaped gap 140 between the facing materials in the partition wall 10D. That is, no facing material 130 is installed between the first intermediate horizontal bar 25A and the second intermediate horizontal bar 26A. In addition, facing material 130 is installed between the upper horizontal bar 23 and the first intermediate horizontal bar 25A, and between the lower horizontal bar 24 and the second intermediate horizontal bar 26A, leaving a gap in the center in the width direction.

[0122] In the sections where the facing material 130 is installed, the vertical length of the gap 140 between the facing materials is the same as the length between the first intermediate horizontal bar 25A and the second intermediate horizontal bar 26A. In the sections where the facing material 130 is not installed, the vertical length of the gap 140 between the facing materials is the same as the height of the partition wall 10D.

[0123] In the areas where the facing material 130 is installed, the width of the gap 140 between the facing materials is approximately half the width of the partition wall 10. In the areas where the facing material 130 is not installed, the width of the gap 140 between the facing materials is the same as the width of the partition wall 10D.

[0124] Similar to the first embodiment, the fifth embodiment reduces manufacturing costs by using fewer parts and small structural plywood that was previously difficult to utilize. On the other hand, since the partition wall 10D is reinforced with multiple facing materials and battens, it is possible to realize a partition wall 10D with excellent seismic resistance. In addition, the gap 140 between the facing materials makes wiring and piping work, as well as the installation and removal of the partition wall 10D, easier, thus reducing the effort required for renovations.

[0125] In addition, according to this embodiment, the first intermediate crossbars 25A and 25B include the first intermediate crossbar 25A, which is positioned at the same height as the lower end of the upper facing material 130A and 130B, so that the lower end of the upper facing material 130A and 130B can be securely attached to the first intermediate crossbar 25A. Furthermore, the second intermediate crossbar 26A includes the second intermediate crossbar 26A, which is positioned at the same height as the upper end of the lower facing material 130C and 130D, so that the upper end of the lower facing material 130C and 130D can be securely attached to the second intermediate crossbar 26A.

[0126] Therefore, the facing material 130 is less prone to damage and peeling from the partition wall body 20D, thus protecting the structure necessary for ensuring earthquake resistance.

[0127] Furthermore, the lower ends of the upper panels 130A and 130B are attached to the first intermediate crossbar 25A, which is positioned at the same height as the lower ends of the panels 130A and 130B. Also, the upper ends of the lower panels 130C and 130D are attached to the second intermediate crossbar 26A, which is positioned at the same height as the upper ends of the panels 130C and 130D.

[0128] Therefore, the lower ends of the upper surface materials 130A and 130B are prevented from protruding downwards more than necessary, and the upper ends of the lower surface materials 130C and 130D are prevented from protruding upwards more than necessary.

[0129] Therefore, since the spacing between the surface materials 130, which are arranged with gaps in the height direction, can be kept wide, a space for tasks such as wiring and piping can be secured as wide as possible not only in the height direction but also in the width direction at the center of the partition wall 10D in the height direction.

[0130] Furthermore, unlike the first embodiment, there are no facing materials or intermediate horizontal bars on the back of the partition wall body 20D, making it possible to assemble wiring and piping more freely.

[0131] Furthermore, since the facing material 130 has different dimensions from the facing material 30, structural plywood that could not be used in the first embodiment can also be used as the facing material 130. In addition, since the facing material 130 is attached to only one side, less structural plywood is required compared to the first embodiment.

[0132] <Variation> The embodiments to which the present invention can be applied are not limited to those described above, and can be modified as appropriate without departing from the spirit of the invention. Modifications are described below. The following modifications may be combined as much as possible. Furthermore, in each of the following modifications, elements common to the above-described embodiments are denoted by the same reference numerals, and their descriptions are omitted or simplified.

[0133] <Example 1> In the above embodiment, the partition wall 10 was adjacent to the second-floor exterior wall panel 51. However, in this modified example, although not shown in the figures, the partition wall 10 is not adjacent to the second-floor exterior wall panel 51. In this modified example, the partition wall 10 is installed so that adjacent partition walls 80 are adjacent to both sides.

[0134] The partition wall 10 has a structure that makes it easy to run wiring and piping through it. In this modified example, the partition wall 10, which was previously located adjacent to the exterior wall 50, is now located away from the exterior wall 50. Therefore, even in a location far from the exterior wall 50, it is possible to ensure that wiring and piping work inside the partition wall can be easily carried out.

[0135] <Modification 2> In the above embodiment, the partition wall 10 had an adjacent partition wall 80 adjacent to its side opposite to the second-floor exterior wall panel 51. In this modified example, although not shown in the figures, a partition wall 10 is placed in place of the adjacent partition wall 80. In other words, two partition walls 10 are provided in a series that are perpendicular to the second-floor exterior wall panel 51 in a plan view.

[0136] In this modified example, multiple partition walls 10 are arranged in a row, making it easy to install wiring and piping inside. Therefore, it is possible to ensure ease of work when running a large amount of wiring and piping into a single room.

[0137] <Variation 3> In the above embodiment, the pair of intermediate crossbars are positioned at the same height, but in this modified example, although not shown, the pair of intermediate crossbars 25A, 25B (26A, 26B) are positioned offset in the height direction.

[0138] In this modified example, the sum of the lengths in the depth direction of the intermediate crossbars 25A (26A) on the front side and the intermediate crossbars 25B (26B) on the back side is greater than or equal to the lengths in the depth direction of the first vertical support 21 and the second vertical bars 22 (22A, 22B). As a result, the pair of intermediate crossbars 25A, 25B (26A, 26B) are offset in the height direction, creating a gap 27 (28) between the upper and lower intermediate crossbars 25A, 25B (26A, 26B).

[0139] The embodiments disclosed herein are for illustrative purposes only and are not intended to limit the scope of the invention. The scope of the invention should be interpreted by the terms of the claims. [Explanation of Symbols]
