MODE FOR CARRYING OUT THE INVENTION

[0012] Embodiments for implementing the present invention will be described in detail while referring to the drawings. The present invention is not limited by the content described in the following embodiments. Further, the constituent elements described below include those that can be easily assumed by those skilled in the art and substantially identical ones. Furthermore, the constituent elements described below can be combined as appropriate. Furthermore, the same reference numerals are assigned to the same-structured parts, and the description thereof is omitted.

[0013] Note that the Z direction is the first direction (height direction), the Z1 side is one side (upper side) of the first direction, and the Z2 side is the other side (lower side) of the first direction. The Y direction is the second direction (the longitudinal direction of the runner, the left-right direction), the Y1 side is one side, and the Y2 side is the other side. The X direction is the third direction (the short-side direction of the runner, the front-rear direction), the X1 side is one side, and the X2 side is the other side.

[0014] First, the schematic configuration of the partition wall according to the embodiment will be described. FIG. 1 is an exploded perspective view of the partition wall according to the embodiment.

[0015] As shown in FIG. 1, the partition wall 100 includes studs 2, a first gypsum board 3, runners 4, mounting brackets 5, and a second gypsum board 6. As the first gypsum board 3, for example, a gypsum board defined by JIS A 6901 (2014), a gypsum board that is lighter or heavier than the above gypsum board (hereinafter, the gypsum board defined by the above JIS and a gypsum board that is lighter or heavier than the gypsum board defined by JIS are collectively referred to as "gypsum board"), a gypsum board, a hard gypsum board, a glass fiber-reinforced gypsum board, a calcium silicate board, etc. One or more types of non-combustible building facings selected therefrom can be preferably used.

[0016] The studs 2 extend in the Z direction. A plurality of studs 2 are arranged at intervals in the Y direction. For example, the distance between adjacent studs 2 in the Y direction is equal. However, the distance between adjacent studs 2 in the Y direction is not particularly limited and may be different intervals. Furthermore, the studs 2 may be arranged in a staggered pattern with respect to the runners 4.

[0017] The first gypsum board 3 is positioned on the X1 side relative to a plurality of studs 2. The first gypsum board 3 may be one sheet or multiple sheets. In this embodiment, a configuration with two sheets will be described. In detail, the first gypsum board 3 has an overlay gypsum board 31 and an underlay gypsum board 32. The overlay gypsum board 31 is positioned on the X1 side relative to the underlay gypsum board 32.

[0018] Runner 4 is a long member extending in the Y direction. Runner 4 has an upper runner 4A and a lower runner 4B. The upper runner 4A has a stud holder 41 and a first gypsum board holder 42. The Z1-side ends 21 of a plurality of studs 2 are inserted into the stud holder 41. The Z1-side ends 3a of the first gypsum board 3 are inserted into the first gypsum board holder 42. End 3a includes the Z1-side end 31a of the overlay gypsum board 31 and the Z1-side end 32a of the underlay gypsum board 32. Therefore, the Z1-side end 31a of the overlay gypsum board 31 and the Z1-side end 32a of the underlay gypsum board 32 are inserted into the first gypsum board holder 42. The lower runner 4B has a bottom surface 4B1 and a pair of flanges 4B2 extending from both ends of the bottom surface 4B1 in the X direction toward the Z1 direction. The lower runner 4B is U-shaped when viewed from the Y direction. The Z2 end 22 of the stud 2 is inserted into the lower runner 4B.

[0019] The mounting bracket 5 is positioned on the X2 side relative to the stud 2. The mounting bracket 5 attaches the first gypsum board 3 to the stud 2.

[0020] The second gypsum board 6 is positioned on the X2 side relative to the multiple studs 2. The second gypsum board 6 may be one sheet or multiple sheets. In this embodiment, a configuration with two sheets will be described. In detail, the second gypsum board 6 has an overlay gypsum board 61 and an underlay gypsum board 62. The overlay gypsum board 61 is positioned on the X2 side relative to the underlay gypsum board 62.

[0021] Next, the configuration of the upper runner 4A will be described. Figure 2 is a perspective view showing a part of the partition wall according to the embodiment. Figure 3A is a perspective view showing the runner according to the embodiment. Figure 3B is a side view of the runner as seen from the side of Figure 3A.

[0022] As described above, the upper runner 4A shown in Figures 2 to 3B has a stud holder 41 and a first gypsum board holder (gypsum board holder) 42. The first gypsum board holder 42 is adjacent to the stud holder 41 on the X1 side. The Z1 side ends 21 of multiple studs 2 are inserted into the stud holder 41. The Z1 side ends 3a of the first gypsum board 3 are inserted into the first gypsum board holder 42.

[0023] The stud holder 41 has a first top surface 411, a first flange 412, and a second flange 413, and is U-shaped when viewed from the Y direction. The first top surface 411 is a plane that intersects the Z direction. The first top surface 411 extends in the Y direction (second direction, longitudinal direction). The first flange 412 bends at the X1 side end of the first top surface 411 and extends toward the Z2 side. The second flange 413 bends at the X2 side end of the first top surface 411 and extends toward the Z2 side.

[0024] The first gypsum board holder 42 has a second top surface 421 and a third flange (gypsum board holder flange) 422. The third flange 422 is also called the gypsum board holder flange. In other words, as shown in Figure 3B, the first gypsum board holder 42 is a portion enclosed by the second top surface 421, the third flange 422, and the first flange 412, with the Z2 side open. The second top surface 421 is a plane extending toward the X1 side from the X1 side end of the first top surface 411. The third flange 422 extends toward the Z2 side from the X1 side end of the second top surface 421. A guide portion 422a may be provided at the Z2 side end of the third flange 422 as needed. The guide portion 422a bends toward the X1 side as it moves toward the Z2 side. This guide portion 422a makes it easier for the end portion 3a of the first gypsum board 3 to be inserted into the first gypsum board holding portion 42 when lifting from the Z2 side to the Z1 side.

[0025] As shown in Figure 3A, the second top surface 421 and the third flange 422 are cut-up pieces 420 obtained by cutting and bending the first flange 412 toward the X1 side. Therefore, an opening 423 is formed in the first flange 412, which becomes the second top surface 421 and the third flange 422. The opening 423 is rectangular when viewed from the X direction. The Z1 side end 3a of the first gypsum board 3 is inserted between the third flange 422 and the first flange 412. The dimensions of the second top surface 421 and the third flange 422 can be changed depending on the thickness and number of first gypsum boards 3 inserted. Multiple first gypsum board holders 42 are arranged at intervals in the Y direction (longitudinal direction, second direction). The distance between adjacent first gypsum board holders 42 in the Y direction may be equal or unequal.

[0026] Next, the mounting bracket 5 will be described. Figure 4 is a perspective view showing a part of the partition wall according to the embodiment. Figure 5A is a perspective view showing the mounting bracket and stud according to the embodiment. Figure 5B is a perspective view showing the stud according to Modification 1 applied to Figure 5A. Figure 6 is a schematic diagram of the mounting bracket according to the embodiment. Figure 7 is a perspective view of the fixing member. The fixing member according to the embodiment can be various types of fixing members, such as screws, bolts, screws, staples, etc. That is, the fixing member can be a wide range of types that fix multiple members together. In Figure 7, a screw is shown as an example of a fixing member. In particular, it is preferable to use Tiger YG screw screws 5.5φ × 38 mm, which are screws for fastening gypsum boards together, for the first fixing member 71.

[0027] As shown in Figures 4 to 6, the mounting bracket 5 has a first surface 51, 51A, a second surface 52, and a third surface 53, 53A. The first surfaces 51, 51A are surfaces facing the back surface 3b of the first gypsum board 3 and are attached to the back surface 3b of the first gypsum board 3. As shown in Figures 5A and 6, the first surface 51 and the third surface 53 are positioned on the Y2 side relative to the stud 2, and the first surface 51A and the third surface 53A are positioned on the Y1 side relative to the stud 2. Through holes 512 are formed in the first surface 51 and the first surface 51A, respectively. As shown in Figure 6, the first surface 51 and the first surface 51A are provided in pairs on both the left and right sides relative to the stud 2. The third surfaces 53, 53A are also provided in pairs on both the left and right sides relative to the stud 2. Furthermore, the first fixing member 71 is inserted into the through hole 512, and the first fixing member 71 is driven into the first gypsum board 3 through the through hole 512.

[0028] Here, the fixing member 7 shown in Figure 7 includes the first fixing members 71, 77, 78 and the second fixing members 72, 73, 74. As shown in Figure 7, the fixing member 7 according to this embodiment has a head portion 7a and a shaft portion 7b. The direction from the head portion 7a to the shaft portion 7b in the fixing member 7 is the direction from the X2 side to the X1 side. As shown in Figure 6, for each of the first surfaces 51 and 51A, the shaft portion 7b of the first fixing member 71 is inserted into the through hole 512, and the shaft portion 7b is driven into the first gypsum board 3. The direction in which the first fixing member 71 is driven is the P1 direction and the P2 direction. In other words, for each of the first surfaces 51 and 51A, the direction from the head portion 7a to the shaft portion 7b (P1 direction, P2 direction) in the first fixing member 71 is the direction from the X2 side to the X1 side.

[0029] Furthermore, as shown in Figure 5A, the stud 2 has an opposing surface 23, a support surface 24, a connecting surface 25, and a bent portion 26. The opposing surface 23 faces the back surface 3b (see Figure 4) of the first gypsum board 3 (gypsum board). The support surface 24 is located on the opposite side of the opposing surface 23. That is, the opposing surface 23 and the support surface 24 face each other in the X direction. The connecting surface 25 extends along the X direction and connects the Y1 side end of the opposing surface 23 and the Y1 side end of the support surface 24. The bent portion 26 bends at the Y2 side end of the opposing surface 23 and the Y2 side end of the support surface 24, respectively, and extends in the X direction.

[0030] As shown in Figures 5A and 6, the second surface 52 of the mounting bracket 5 faces the support surface 24 of the stud 2. The second surface 52 extends in the Y direction from end 521 to end 522. The second surface 52 is fixed to the support surface 24 via a fixing member 73. That is, the fixing member 73 has a head 7a and a shaft 7b, the shaft 7b is inserted into the through hole 523 and the shaft 7b is driven into the support surface 24 of the stud 2. The direction in which the fixing member 73 is driven is the P3 direction. In other words, in the fixing member 73, the direction from the head 7a to the shaft 7b (P3 direction) is the direction from the X2 side to the X1 side. Note that the fixing member 73 is not necessarily required, and an embodiment without the fixing member 73 (simply an embodiment in which the second surface 52 faces the support surface 24 of the stud 2) is also applicable.

[0031] The third surface 53 connects the first surface 51 and the second surface 52. The third surface 53 extends in the X direction from end 511 to end 521, connecting the first surface 51 and the second surface 52. The third surface 53A extends in the X direction from end 511A to end 522, connecting the first surface 51A and the second surface 52.

[0032] Furthermore, as shown in Figure 5B, the stud 2A according to Modification 1 can also be applied. The stud 2A is rectangular when viewed from the Z direction. The connecting surface 27 of the stud 2A is different from that of the stud 2. That is, in the stud 2A, the support surface 24 and the opposing surface 23 are connected by a connecting surface 25 and a connecting surface 27 that extend in the X direction.

[0033] Next, we will compare and explain the deformation state of the first gypsum board 3 in the case where the mounting bracket 5 is applied and in the case where the mounting bracket 5 is not applied. Figure 8A is a schematic diagram showing the amount of deformation of the first gypsum board in the case where the mounting bracket is not applied. Figure 8B is a schematic diagram showing the amount of deformation of the first gypsum board in the case where the mounting bracket is applied.

[0034] As shown in Figure 8A, the upper end of the first gypsum board 3 is held by the first gypsum board holder 42, and the lower end is fixed to the stud 2 via the fixing member 74. Therefore, as shown in Figure 8A, if the mounting bracket 5 is not applied, the central part of the first gypsum board 3 in the height direction is not held, and may deform and curve towards X1 by the deformation amount D1 indicated by the arrow.

[0035] In contrast, when two mounting brackets 5 are applied to one stud 2 (in the Z direction), as shown in Figure 8B, the central part of the first gypsum board 3 in the height direction (Z direction) is held to the stud 2 via the two mounting brackets 5. Specifically, two mounting brackets 5 are placed at approximately equal intervals in the height direction of the first gypsum board 3 for one stud 2, and the first fixing member 71 is driven into the first gypsum board 3 to hold the first gypsum board 3 to the stud 2. In this case, as shown in Figure 8B, the board deforms towards X1 by a deformation amount D2 indicated by the arrow, resulting in a slightly curved shape. However, since the deformation amount D2 is very small compared to the deformation amount D1, applying the mounting brackets 5 results in less deformation of the first gypsum board 3. Note that the number of mounting brackets 5 is not limited to two per stud; it may be one or three or more. Also, the position in the Z direction where the mounting brackets 5 are placed is not particularly limited.

[0036] Next, we will describe modified versions of the mounting bracket. Figure 9 is a schematic diagram of the mounting bracket according to Modification 2. Figure 10 is a schematic diagram of the mounting bracket according to Modification 3.

[0037] As shown in Figure 9, the mounting bracket 5A according to the modified example 2 lacks the third surface 53A and the first surface 51A compared to the mounting bracket 5 shown in Figure 6. In other words, the mounting bracket 5A consists of a first surface 51, a second surface 52, and a third surface 53. The first surface 51 is fixed to the first gypsum board 3, and the second surface 52 is held by the stud 2. Because the mounting bracket 5A lacks the third surface 53A and the first surface 51A compared to the mounting bracket 5, it has the advantage of being lighter in weight than the mounting bracket 5.

[0038] As shown in Figure 10, the mounting bracket 5B according to the modified example 3 differs from the mounting bracket 5A shown in Figure 9 in that it has a bent portion 53B. That is, the mounting bracket 5B consists of a first surface 51, a second surface 52, a third surface 53, and a bent portion 53B. The bent portion 53B bends toward the X1 side at end 522 and extends to end 53B1. The bent portion 53B abuts against the connecting surface 25 of the stud 2 shown in Figure 5A. The mounting bracket 5B has the advantage of being lighter in weight than the mounting bracket 5 because it does not have the first surface 51A.

[0039] Next, a method for assembling a partition wall will be described. Figure 11A is a schematic diagram showing the first step in the partition wall assembly method according to the embodiment. Figure 11B is a schematic diagram showing the first step in the partition wall assembly method according to the embodiment. Figure 11C is a schematic diagram showing the second step in the partition wall assembly method according to the embodiment. Figure 11D is a schematic diagram showing the third step in the partition wall assembly method according to the embodiment. The partition wall assembly method includes the first step, the second step, and the third step. In this embodiment, a method for assembling a partition wall 100 at the corner of a structure 8 including a first structure 81 and a second structure 82 will be described. The first structure 81 is, for example, a ceiling, and the second structure 82 is, for example, a beam, a column, and a wall. The second structure 82 has a side surface 82a extending in the Z direction and a bottom surface 82b extending in the X direction. A detailed explanation follows below.

[0040] (Step 1) The first step is to support the stud 2 and the first gypsum board 3 on the upper runner 4A (runner). The upper runner 4A is fixed to the first structure 81. In detail, as shown in Figure 11A, first, the stud 2 is lifted upward (towards Z1), and the upper end of the stud 2 is inserted into the stud holding portion 41 of the upper runner 4A. Next, the underlayment gypsum board 32 is lifted upward (towards Z1), and the end portion 32a of the underlayment gypsum board 32 is inserted into the first gypsum board holding portion 42 of the upper runner 4A. After this, a fixing member 74 is driven into the lower end portion 32b of the underlayment gypsum board 32 and the stud 2. The fixing member 74 is driven in from the X1 side to the X2 side. The height position of the fixing member 74 is below (towards Z2) the bottom surface 82b of the second structure 82. Furthermore, the underlayment gypsum board 32 may have its short side oriented in the Z direction, or its long side oriented in the Z direction. Also, the lower end 31b of the toplayment gypsum board 31 and the lower end 32b of the underlayment gypsum board 32 do not overlap with the second structure 82 when viewed from the X direction.

[0041] Then, as shown in Figure 11B, adhesive 110 is applied to multiple locations on the back of the overlay gypsum board 31, the overlay gypsum board 31 is lifted upward (towards Z1), the end 31a of the overlay gypsum board 31 is inserted into the first gypsum board holding part 42 of the upper runner 4A, and the back of the overlay gypsum board 31 is bonded to the underlay gypsum board 32 via adhesive 110. After this, staples 75 are driven into the lower end 31b of the overlay gypsum board 31 and the lower end 32b of the underlay gypsum board 32. The staples 75 are driven from the X1 side towards the X2 side.

[0042] (Step 2) The second step is to fix the first gypsum board 3 to the stud 2 via mounting brackets 5. Specifically, mounting brackets 5 are placed on the upper side (Z1 side) and lower side (Z2 side) of the stud 2 in the Z direction, respectively, and as shown in Figures 6 and 11C, the first surfaces 51 and 51A of the mounting brackets 5 are fixed to the first gypsum board 3, and the second surface 52 of the mounting brackets 5 is fixed to the stud 2 via the first fixing members 71 and 73. That is, the first fixing members 71 and 73 are driven in in the P1, P2, and P3 directions. The P1, P2, and P3 directions are all the same, and are directions from the X2 side to the X1 side. Note that the number of mounting brackets 5 is not limited to two, and may be one or three or more. Furthermore, the position in the Z direction in which the mounting brackets 5 are placed is not particularly limited.

[0043] (Step 3) The third step is to fix the second gypsum board 6 to the stud 2. In detail, as shown in Figure 11D, first, the underlayment gypsum board 62 is lifted upward (towards Z1) from the X2 side relative to the stud 2, and the second fixing member 72 is driven into the underlayment gypsum board 62 and the stud 2. The second fixing member 72 is driven in from the X2 side toward the X1 side. Multiple second fixing members 72 are driven in at intervals in the Z direction.

[0044] Next, adhesive 110 is applied to multiple locations on the back of the top gypsum board 61, the top gypsum board 61 is lifted upwards (towards Z1), and the back of the top gypsum board 61 is bonded to the underlayment gypsum board 62 via the adhesive 110. After this, staples 76 are driven into the top gypsum board 61 and the underlayment gypsum board 62. The staples 76 are driven from the X2 side towards the X1 side. Multiple staples 76 are driven in at intervals in the Z direction.

[0045] Next, we will compare and explain two configurations: one in which the tip of the fixing member protrudes beyond the surface of the gypsum board, and another in which the tip of the fixing member is located inside the gypsum board. Figure 12A is a schematic diagram showing the state in which the tip of the fixing member penetrates the first gypsum board. Figure 12B is a schematic diagram showing the state in which the tip of the fixing member is located inside the first gypsum board.

[0046] As shown in Figure 12A, the tip 7c of the shaft portion 7b of the first fixing member 77 protrudes through the overlay gypsum board 31 towards X1. In this case, the convex portion on the outer circumference of the shaft portion 7b bites into both the overlay gypsum board 31 and the underlay gypsum board 32, thus increasing the holding force when fixing the first surface 51 of the mounting bracket 5 to the overlay gypsum board 31 and the underlay gypsum board 32. The configuration shown in Figure 12A can be applied when the gap with the beam is narrow and the fixing member is not visible from below, when no one will touch the protruding fixing member, or when no finishing work is required.

[0047] In contrast, as shown in Figure 12B, the tip 7c of the shaft portion 7b of the first fixing member 78 is located inside the overlay gypsum board 31 without penetrating it. In this case, since the tip 7c of the shaft portion 7b does not protrude from the overlay gypsum board 31, it is possible to suppress the feeling of discomfort in the hands or fingers of workers or residents when they touch the surface of the overlay gypsum board 31. As shown in Figures 12A and 12B, pilot holes (guides) may be formed using a tool such as a drill before driving the first fixing members 77 and 78 into the overlay gypsum board 31 and the underlay gypsum board 32. Specifically, the tip of the tool is inserted into the through hole 512 (see Figure 6) in the first surface 51 of the mounting bracket 5, and the tool is operated to form pilot holes (guides) that penetrate the overlay gypsum board 31 and the underlay gypsum board 32 as shown in Figures 12A and 12B.

[0048] As described above, the partition wall 100 according to this embodiment comprises a stud 2, a first gypsum board 3, an upper runner 4A (runner 4), a mounting bracket 5, a second gypsum board 6, a first fixing member 71, and a second fixing member 72. The first gypsum board 3 is located on the X1 side relative to the stud 2. The mounting bracket 5 is positioned on the X2 side relative to the stud 2 and attaches the first gypsum board 3 to the stud 2. The second gypsum board 6 is positioned on the X2 side relative to the stud 2. The first fixing member 71 fixes the mounting bracket 5 to the first gypsum board 3. The second fixing member 72 fixes the second gypsum board 6 to the stud 2. The staples 76 fix the upper gypsum board 61 and the lower gypsum board 62. In both the first fixing member 71 and the second fixing member 72, the direction from the head 7a toward the shaft portion 7b is the same. In detail, in each of the first fixing member 71 and the second fixing member 72, the direction from the head portion 7a toward the shaft portion 7b is the direction from the X2 side toward the X1 side.

[0049] In the aforementioned Patent Document 1, the installation space between the beam and the first gypsum board is narrow, making it difficult to drive screws, staples, etc., into the portion of the first gypsum board facing the beam. Consequently, the rigidity of the first gypsum board facing the beam may decrease.

[0050] In contrast, the partition wall 100 according to this embodiment has mounting brackets 5. The mounting brackets 5 are positioned on the X2 side relative to the studs 2 and attach the first gypsum board 3 to the studs 2. Therefore, when constructing the partition wall 100 in a location with limited construction space, it is possible to increase the rigidity of the first gypsum board 3. Furthermore, by providing multiple mounting brackets 5, it is possible to further increase the rigidity of the first gypsum board 3.

[0051] Furthermore, the first fixing member 71 fixes the mounting bracket 5 to the first gypsum board 3, and the second fixing member 72 fixes the second gypsum board 6 to the stud 2. The staples 76 fix the top gypsum board 61 to the bottom gypsum board 62. In both the first fixing member 71 and the second fixing member 72, the direction from the head 7a toward the shaft 7b is the same. In other words, the direction in which the first fixing member 71 and the second fixing member 72 are driven in is the same. That is, in general construction, the directions in which the first fixing member 71 and the second fixing member 72 are driven in may be different, but according to this embodiment, the direction in which the first fixing member 71 and the second fixing member 72 are driven in can be the same.

[0052] The mounting bracket 5 also has a first surface 51, a second surface 52, and a third surface 53. The first surface 51 is fixed to the X2 side surface of the first gypsum board 3 via a first fixing member 71. The second surface 52 faces the support surface 24 of the stud 2.

[0053] In this way, the first gypsum board 3 can be attached to the stud 2 with a simple structure. The second surface 52 may also be fixed to the support surface 24 of the stud 2 via a fixing member, in which case the mounting bracket 5 can be firmly fixed to the support surface 24 of the stud 2.

[0054] Furthermore, the mounting bracket 5 has a pair of first surfaces 51, a second surface 52, and a pair of third surfaces 53. The pair of first surfaces 51 and the pair of third surfaces 53 are positioned on the Y1 side and the Y2 side, with the stud 2 in between.

[0055] This increases the rigidity of the mounting bracket 5 itself. In addition, since the pair of left and right first surfaces 51 are fixed to the first gypsum board 3, the rigidity of the first gypsum board 3 is further increased.

[0056] The upper runner 4A (runner 4) has a stud holding portion 41 and a first gypsum board holding portion (gypsum board holding portion) 42. This allows for more robust support of the upper end of the stud 2 and the upper end of the first gypsum board 3.

[0057] Furthermore, the stud retaining portion 41 has a first top surface 411, a first flange 412, and a second flange 413. The first gypsum board retaining portion (gypsum board retaining portion) 42 has a second top surface 421 and a third flange (gypsum board retaining portion flange) 422. The first gypsum board retaining portion 42 is a cut-up piece 420 obtained by cutting and bending a part of the first flange 412 in a rectangular shape toward the X1 side. Thus, the first gypsum board retaining portion 42 is a cut-up piece 420. Therefore, compared to the embodiment described in Patent Document 1 above, in which the stud retaining portion 41 and the first gypsum board retaining portion 42 are made separately and then joined together, the upper runner 4A is lighter.

[0058] Furthermore, the first gypsum board holding parts (gypsum board holding parts) 42 are arranged in multiples at intervals in the Y direction. Therefore, the upper runner 4A is lighter compared to an configuration in which the first gypsum board holding parts extend continuously in the Y direction.

[0059] The method for assembling the partition wall includes a first step of supporting the studs 2 and the first gypsum board 3 on the upper runner 4A (runner), a second step of fixing the first gypsum board 3 to the studs 2 via mounting brackets 5, and a third step of fixing the second gypsum board 6 to the studs 2. The first fixing member 71 and the second fixing member 72 are driven in in the same direction.

[0060] Thus, since the first fixing member 71 and the second fixing member 72 are driven in in the same direction, the work of fixing the mounting bracket 5 to the first gypsum board 3 and the work of fixing the second gypsum board 6 to the stud 2 become easier.

[0061] Furthermore, in the construction of a typical partition wall, the directions in which the first fixing member 71 and the second fixing member 72 are driven into the ground may differ. However, according to this embodiment, the directions in which the first fixing member 71 and the second fixing member 72 are driven into the ground can be the same. In other words, since the partition wall 100 can be constructed from only one side, even in locations where construction space can only be secured on one side of the partition wall 100, it becomes possible to install the partition wall 100 with the rigidity of the wall ensured by the mounting bracket 5.
