[0003] Patent Document 1 Japanese Unexamined Patent Application Publication No. 2014-177799 Summary of the Invention Problems to be Solved by the Invention

[0004] There is a demand for suitably joining a brace to a joining object by a joint metal fitting. Means for Solving the Problems

[0005] (1) A building that solves the above problem is a building comprising a frame composed of a plurality of axial members, a brace having a rod-shaped brace body and connecting plates provided at both ends of the brace body, and a brace connecting member that connects the brace to the frame, wherein the frame is provided with a plurality of connecting holes, the connecting plate is provided with plate through holes, the brace connecting member has a first plate and a second plate, the first plate is provided with a first through hole and a second through hole extending in the same direction as the first through hole, and the second plate The plate is provided with a third through-hole and a fourth through-hole extending in the same direction as the third through-hole. The first plate and the second plate are connected to the brace by a first connecting member inserted through the plate through-hole, the first through-hole, and the third through-hole. The first plate is connected to the frame by a second connecting member inserted through the connecting hole and the second through-hole. The second plate is connected to the frame by a third connecting member inserted through a connecting hole different from the connecting hole through which the second connecting member is inserted, and through the fourth through-hole.

[0006] In this configuration, when the connection between the connecting plate, the first plate, and the second plate by the first connecting member is loosened, the first plate and the second plate are each rotatable relative to the connecting plate with the first connecting member as the axis of rotation. Therefore, the direction in which the first plate and the second plate extend can be adjusted. This allows the brace connecting member to be connected to the frame in a way that prevents it from interfering with other members connected to the frame.

[0007] Furthermore, according to the above configuration, the connecting hole through which the second connecting member is inserted and the connecting hole through which the third connecting member is inserted are different. That is, the connection position of the first plate to the frame and the connection position of the second plate to the frame are different. Therefore, the brace connecting member can be stably connected to the frame. Consequently, the brace can be suitably connected to the frame.

[0008] (2) In the building described in (1) above, the plurality of shaft members include a first shaft member, the plurality of connecting holes include a plurality of first connecting holes provided in the first shaft member, the first plate is connected to the first shaft member by a second connecting member inserted through the first connecting hole and the second through hole, and the second plate is connected to the first shaft member by a third connecting member inserted through a first connecting hole and a fourth through hole different from the first connecting hole through which the second connecting member is inserted.

[0009] This configuration allows braces to be connected to different positions on the same shaft member. Therefore, for example, if the shaft assembly does not have an intersection where two shaft members intersect, or if other members are connected to the intersection, braces can be connected to the shaft assembly.

[0010] (3) In the building described in (2) above, the first axial member further comprises a plate material extending in the direction in which the first axial member extends, wherein the angle between a reference line extending in the direction in which the first axial member extends and a first imaginary line extending in the direction in which the brace body extends is a first angle, the angle between a second imaginary line connecting the first through hole and the second through hole and the reference line is a second angle, the angle between a third imaginary line connecting the third through hole and the fourth through hole and the reference line is a third angle, the second angle and the third angle are each greater than the first angle, and the plate material is provided with plate insertion holes through which the first plate and the second plate are inserted.

[0011] This configuration reduces the amount of material loss in the plate material in the direction in which the first axial member extends, compared to a case where the brace is directly connected to the first axial member and brace insertion holes are provided in the plate material through which the brace is inserted.

[0012] (4) In the building described in (1) above, the plurality of shaft members include a first shaft member and a second shaft member intersecting the first shaft member, the plurality of connecting holes include a plurality of first connecting holes provided in the first shaft member and a plurality of second connecting holes provided in the second shaft member, the first plate is connected to the first shaft member by the second connecting members inserted through the first connecting holes and the second through holes, and the second plate is connected to the second shaft member by the third connecting members inserted through the second connecting holes and the fourth through holes. With this configuration, a brace can be connected to the intersection where the first axis member and the second axis member intersect.

[0013] (5) A construction method for constructing a building as described in any one of (1) to (4) above includes a frame construction step of constructing the shaft member to which the brace connecting member is temporarily connected, and a brace construction step of connecting the brace to the shaft member using the brace connecting member which is temporarily connected to the shaft member. This method allows for the pre-temporary attachment of brace connecting members to the shaft members, thus preventing omissions during brace installation.

[0014] (6) In the construction method of the building described in (5) above, the brace connecting member is temporarily connected to the shaft member so as not to protrude from the shaft member. This method prevents the brace connecting members from getting in the way during transportation or installation of the shaft members.

[0015] (7) In the construction method of the building described in (5) or (6) above, the brace connecting member is temporarily connected to the shaft member in the brace construction process. This method allows the brace installation process to be carried out without removing the brace connecting member that is temporarily connected to the shaft member.

[0016] (8) A brace connecting member that solves the above problems connects a brace having a rod-shaped brace body and connecting plates provided at both ends of the brace body and having plate through holes to a frame made up of a plurality of shaft members and having a plurality of connecting holes, the brace connecting member having a first plate and a second plate, the first plate having a first through hole through which a first connecting member that is inserted and connects the first plate and the second plate to the brace is inserted, and The first plate is provided with a second through-hole through which a second connecting member, which connects the first plate to the frame, is inserted, and the second through-hole extends in the same direction as the first through-hole. The second plate is provided with a third through-hole through which the first connecting member is inserted, and a fourth through-hole through which a third connecting member, which connects the second plate to the frame, is inserted, and the fourth through-hole extends in the same direction as the third through-hole.

[0017] In this configuration, when the connection between the connecting plate, the first plate, and the second plate by the first connecting member is loosened, the first plate and the second plate are each rotatable relative to the connecting plate with the first connecting member as the axis of rotation. Therefore, the direction in which the first plate and the second plate extend can be adjusted. This allows the brace connecting member to be connected to the frame in a way that prevents it from interfering with other members connected to the frame.

[0018] By adjusting the direction in which the first plate and the second plate extend, the connecting hole through which the second connecting member is inserted and the connecting hole through which the third connecting member is inserted can be made different. In other words, the connection position of the first plate to the frame and the connection position of the second plate to the frame can be made different. Therefore, the brace connecting member can be stably connected to the frame. Consequently, the brace can be suitably connected to the frame. [Effects of the Invention]

[0019] According to the building, building construction method, and brace connecting member of the present disclosure, a brace can be suitably connected to a framework. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] With reference to FIGS. 1 to 4, a building 10, a construction method for the building 10, and a brace connecting member 14 according to the present embodiment will be described. As shown in FIGS. 1 and 2, the building 10 includes a framework 11, two braces 12, and a plate member 13. In the following description, when distinguishing between the two braces 12, one brace 12 is referred to as a first brace 12a, and the other brace 12 is referred to as a second brace 12b.

[0022] <Framework 11> The framework 11 is constituted by a plurality of shaft members 20. In the present embodiment, the plurality of shaft members 20 include a first shaft member 21, a second shaft member 22, a third shaft member 23, and a fourth shaft member 24. The first shaft member 21, the second shaft member 22, the third shaft member 23, and the fourth shaft member 24 are each horizontal members extending in the horizontal direction. The length of each of the first shaft member 21 and the third shaft member 23 is longer than the length of each of the second shaft member 22 and the fourth shaft member 24.

[0023] The first shaft member 21 and the third shaft member 23 extend in parallel. The second shaft member 22 and the fourth shaft member 24 extend in parallel. The direction in which the second shaft member 22 and the fourth shaft member 24 extend intersects with the direction in which the first shaft member 21 and the third shaft member 23 extend. In this embodiment, the direction in which the second shaft member 22 and the fourth shaft member 24 extend is perpendicular to the direction in which the first shaft member 21 and the third shaft member 23 extend. The second shaft member 22 connects the first end of the first shaft member 21 and the first end of the third shaft member 23. The fourth shaft member 24 connects the second end of the first shaft member 21 and the second end of the third shaft member 23.

[0024] The frame 11 has a frame 11a composed of a first axis member 21, a second axis member 22, a third axis member 23, and a fourth axis member 24. The frame 11a in this embodiment is rectangular in shape. The first axis member 21 and the third axis member 23 constitute the long sides of the frame 11a. The second axis member 22 and the fourth axis member 24 constitute the short sides of the frame 11a.

[0025] As shown in Figure 3, the shaft member 20 in this embodiment is made of H-shaped steel. The shaft member 20 has a web 25, an upper flange 26 provided at the upper end of the web 25, and a lower flange 27 provided at the lower end of the web 25.

[0026] As shown in Figure 1, the shaft assembly 11 is provided with a plurality of connecting holes 20h. In this embodiment, the plurality of connecting holes 20h include a plurality of first connecting holes 21h provided in the first shaft member 21, a plurality of second connecting holes 22h provided in the second shaft member 22, a plurality of third connecting holes 23h provided in the third shaft member 23, and a plurality of fourth connecting holes 24h provided in the fourth shaft member 24. The connecting holes 20h penetrate the lower flange 27 in the thickness direction. The plurality of connecting holes 20h provided in each shaft member 20 are spaced apart in the direction in which the shaft member 20 extends.

[0027] <Brace 12> The brace 12 has a rod-shaped brace body 30 and connecting plates 34 provided at both ends of the brace body 30. In other words, the brace 12 has two connecting plates 34. When distinguishing between the two connecting plates 34, one connecting plate 34 is called the first connecting plate 34a and the other connecting plate 34 is called the second connecting plate 34b.

[0028] The brace body 30 includes a first rod 31, a second rod 32, and a turnbuckle 33. In this embodiment, the length of the second rod 32 is longer than the length of the first rod 31. The turnbuckle 33 connects the first end of the first rod 31 to the first end of the second rod 32.

[0029] The first connecting plate 34a is flat. The first connecting plate 34a is provided at the second end of the first rod 31. The first connecting plate 34a is welded to the second end of the first rod 31. The first connecting plate 34a is located at the first end of the brace 12.

[0030] The second connecting plate 34b is flat. The second connecting plate 34b is provided at the second end of the second rod 32. The second connecting plate 34b is welded to the second end of the second rod 32. The second connecting plate 34b is located at the second end of the brace 12.

[0031] As shown in Figure 3, the connecting plate 34 is provided with a plate through-hole 34h. The plate through-hole 34h penetrates the connecting plate 34 in the thickness direction. The plate through-hole 34h extends in a direction perpendicular to the direction in which the brace body 30 extends.

[0032] As shown in Figure 1, the two braces 12 extend horizontally within the frame 11a. The direction in which the braces 12 extend is inclined with respect to both the direction in which the first axial member 21 and the third axial member 23 extend, and the direction in which the second axial member 22 and the fourth axial member 24 extend.

[0033] The first brace 12a extends from the intersection of the first shaft member 21 and the second shaft member 22 to the intersection of the third shaft member 23 and the fourth shaft member 24. Both ends of the first brace 12a are connected to the shaft assembly 11 via brace connecting members 14, which will be described later. In this embodiment, the first end of the first brace 12a is connected to a portion of the first shaft member 21 near the first end via the first brace connecting member 14a, which is the brace connecting member 14. The second end of the first brace 12a is connected to a portion of the third shaft member 23 near the second end via the second brace connecting member 14b, which is the brace connecting member 14.

[0034] The second brace 12b extends from the intersection of the second shaft member 22 and the third shaft member 23 to the intersection of the first shaft member 21 and the fourth shaft member 24. Both ends of the second brace 12b are connected to the shaft assembly 11 via brace connecting members 14. In this embodiment, the first end of the second brace 12b is connected to a portion of the third shaft member 23 near the first end via a third brace connecting member 14c, which is a brace connecting member 14. The second end of the second brace 12b is connected to a portion of the first shaft member 21 near the second end via a fourth brace connecting member 14d, which is a brace connecting member 14.

[0035] The first brace 12a and the second brace 12b intersect within the frame 11a. In this embodiment, the second bar 32 of the first brace 12a and the second bar 32 of the second brace 12b intersect.

[0036] <Brace connecting member 14> The brace connecting members 14 for connecting the brace 12 to the frame 11 will be described in detail. In the following description, the first brace connecting member 14a will be described. The second brace connecting member 14b, the third brace connecting member 14c, and the fourth brace connecting member 14d have the same structure as the first brace connecting member 14a, so their description will be omitted and they will be given the same reference numerals.

[0037] As shown in Figures 2 to 4, the brace connecting member 14 has a first plate 41 and a second plate 42. The first plate 41 and the second plate 42 have the same shape when viewed from the thickness direction. In this embodiment, the edges of the first plate 41 and the second plate 42 each have two parallel straight sections and two arc sections connecting the two straight sections. In the following description, the direction in which the two straight sections extend will be referred to as the direction in which the first plate 41 and the second plate 42 extend.

[0038] The first plate 41 is provided with a first through hole 41a and a second through hole 41b. The first through hole 41a and the second through hole 41b each penetrate the first plate 41 in the thickness direction. Therefore, the second through hole 41b extends in the same direction as the first through hole 41a. The first through hole 41a is provided at the first end in the direction in which the first plate 41 extends. The second through hole 41b is provided at the second end in the direction in which the first plate 41 extends. The direction in which the first through hole 41a and the second through hole 41b are aligned is the same direction in which the first plate 41 extends.

[0039] At the second end of the first plate 41 in the direction in which it extends, a projection 41c is provided that protrudes in the thickness direction from one surface of the first plate 41. Therefore, the thickness of the second end of the first plate 41 in the direction in which it extends is greater than the thickness of other parts of the first plate 41. In this embodiment, the amount of protrusion of the projection 41c from one surface of the first plate 41 is approximately the same as the thickness of the second plate 42.

[0040] The second plate 42 is provided with a third through hole 42a and a fourth through hole 42b. The third through hole 42a and the fourth through hole 42b each penetrate the second plate 42 in the thickness direction. Therefore, the fourth through hole 42b extends in the same direction as the third through hole 42a. The third through hole 42a is provided at the first end in the direction in which the second plate 42 extends. The fourth through hole 42b is provided at the second end in the direction in which the second plate 42 extends. The direction in which the third through hole 42a and the fourth through hole 42b are aligned is the same direction in which the second plate 42 extends. The thickness of the second plate 42 is the same throughout the entire second plate 42.

[0041] The first end of the first plate 41, the first end of the second plate 42, and the connecting plate 34 are arranged in overlapping positions such that the first through hole 41a, the third through hole 42a, and the plate through hole 34h are in communication with each other. The thickness direction of the first plate 41, the thickness direction of the second plate 42, and the thickness direction of the connecting plate 34 are all in the same direction.

[0042] In this embodiment, the first end of the first plate 41 is located between the connecting plate 34 and the first end of the second plate 42. The first end of the first plate 41 is located above the first end of the second plate 42. The connecting plate 34 is located above the first end of the first plate 41. When viewed from a direction perpendicular to the thickness direction of the first plate 41, the second plate 42, and the connecting plate 34, the tip surface of the projection 41c is located substantially on the same plane as the surface of the second plate 42 opposite to the surface facing the first plate 41.

[0043] The first plate 41 and the second plate 42 are connected to the connecting plate 34 by a first bolt 15a and a first nut 15b, which serve as a first connecting member. Specifically, the first bolt 15a is inserted through the first through hole 41a, the third through hole 42a, and the plate through hole 34h, and the first nut 15b is locked onto the first bolt 15a. When the connection between the first plate 41, the second plate 42, and the connecting plate 34 by the first connecting member is loosened, the first plate 41 and the second plate 42 are each rotatable relative to the connecting plate 34 with the shaft of the first bolt 15a as the axis of rotation.

[0044] The second end of the first plate 41 is positioned on the upper surface of the lower flange 27 of the first shaft member 21 such that the second through hole 41b communicates with the first connecting hole 21h. The thickness direction of the first plate 41 is the same as the thickness direction of the lower flange 27. The tip surface of the protrusion 41c is in contact with the upper surface of the lower flange 27.

[0045] The first plate 41 is connected to the first shaft member 21 by a second bolt 16a and a second nut 16b, which serve as a second connecting member. Specifically, the second bolt 16a is inserted through a second through hole 41b and a first connecting hole 21h, and the second nut 16b is locked onto the second bolt 16a. When the connection between the first plate 41 and the first shaft member 21 by the second connecting member is loosened, the first plate 41 is rotatable relative to the first shaft member 21 with the shaft portion of the second bolt 16a as the axis of rotation.

[0046] The second end of the second plate 42 is positioned on the upper surface of the lower flange 27 of the first shaft member 21 such that the fourth through hole 42b communicates with the first connecting hole 21h. The first connecting hole 21h through which the fourth through hole 42b communicates is a different first connecting hole 21h from the first connecting hole 21h through which the second through hole 41b communicates. The thickness direction of the second plate 42 is the same as the thickness direction of the lower flange 27. The lower surface of the second plate 42 is in contact with the upper surface of the lower flange 27.

[0047] The second plate 42 is connected to the first shaft member 21 by a third bolt 17a and a third nut 17b, which serve as a third connecting member. Specifically, the third bolt 17a is inserted through a fourth through hole 42b and a first connecting hole 21h, and the third nut 17b is locked onto the third bolt 17a. When the connection between the second plate 42 and the first shaft member 21 by the third connecting member is loosened, the second plate 42 is rotatable relative to the first shaft member 21 with the shaft portion of the third bolt 17a as the axis of rotation.

[0048] As shown in Figure 1, the first connecting hole 21h through which the second bolt 16a is inserted is different from the first connecting hole 21h through which the third bolt 17a is inserted. In this embodiment, the second bolt 16a is inserted into the fourth connecting hole 21h from the first end of the first shaft member 21, among a plurality of first connecting holes 21h arranged in the direction in which the first shaft member 21 extends. The third bolt 17a is inserted into the third connecting hole 21h from the first end of the first shaft member 21, among a plurality of first connecting holes 21h arranged in the direction in which the first shaft member 21 extends.

[0049] Thus, the first plate 41 is connected to the first shaft member 21 by a second bolt 16a inserted through one of the multiple first connecting holes 21h and a second through hole 41b. The second plate 42 is connected to the first shaft member 21 by a third bolt 17a inserted through a first connecting hole 21h different from the first connecting hole 21h through which the second bolt 16a is inserted and a fourth through hole 42b.

[0050] Therefore, the connection position of the first plate 41 to the first shaft member 21 is different from the connection position of the second plate 42 to the first shaft member 21. In other words, the first plate 41 and the second plate 42 are connected to different positions on the same shaft member 20. In this embodiment, the distance from the intersection of the first shaft member 21 and the second shaft member 22 to the connection position of the first plate 41 to the first shaft member 21 is greater than the distance from the intersection of the first shaft member 21 and the second shaft member 22 to the connection position of the second plate 42 to the first shaft member 21.

[0051] As described above, the connection positions of the first plate 41 and the second plate 42 to the first connecting plate 34a of the brace 12 are the same. On the other hand, the connection positions of the first plate 41 and the second plate 42 to the first shaft member 21 are different. Therefore, the direction in which the first plate 41 extends and the direction in which the second plate 42 extends are different from each other. In this embodiment, the direction in which the first plate 41 extends and the direction in which the second plate 42 extends are different from the direction in which the brace body 30 extends.

[0052] As shown in Figure 2, the reference line L is a virtual line extending along the direction in which the first shaft member 21 extends. The first virtual line L1 is a virtual line extending along the direction in which the brace body 30 extends. The angle between the reference line L and the first virtual line L1 is the first angle A1. The second virtual line L2 is a virtual line connecting the first through hole 41a and the second through hole 41b of the first plate 41. The angle between the reference line L and the second virtual line L2 is the second angle A2. The second angle A2 is greater than the first angle A1. The third virtual line L3 is a virtual line connecting the third through hole 42a and the fourth through hole 42b of the second plate 42. The angle between the reference line L and the third virtual line L3 is the third angle A3. The third angle A3 is greater than the first angle A1. In this embodiment, the third angle A3 is the same angle as the second angle A2.

[0053] In this embodiment, the first plate 41 and the second plate 42 of the brace connecting member 14 are temporarily connected to the shaft member 20 at the factory. The brace connecting member 14 is temporarily connected to the shaft member 20 at the position where it will be permanently connected in the brace construction process described later. The brace connecting member 14 is also temporarily connected to the shaft member 20 so as not to protrude from it. The shaft member 20 is transported to the site with the brace connecting member 14 temporarily connected to it.

[0054] In the case of the first brace connecting member 14a, the first plate 41 and the second plate 42 are temporarily connected to the first shaft member 21, as shown by the dashed line in Figure 2. The first plate 41 and the second plate 42 are temporarily connected to the position where they will be permanently connected to the first shaft member 21 during the brace construction process. Specifically, the first plate 41 is temporarily connected to the first shaft member 21 by a second bolt 16a inserted through the first connecting hole 21h and the second through hole 41b, which are located fourth from the first end of the first shaft member 21. The second plate 42 is temporarily connected to the first shaft member 21 by a third bolt 17a inserted through the first connecting hole 21h and the fourth through hole 42b, which are located third from the first end of the first shaft member 21.

[0055] In the state where the first plate 41 and the second plate 42 are temporarily connected to the first shaft member 21, the first plate 41 and the second plate 42 each extend in the direction in which the first shaft member 21 extends. Therefore, in a plan view, the first plate 41 and the second plate 42 do not protrude from the first shaft member 21.

[0056] <Plate material 13> As shown in Figures 1 and 2, the plate material 13 is positioned inside the frame 11a in a plan view. The plate material 13 has a first plate portion 13a that extends in the direction in which the first shaft member 21 extends, and a second plate portion 13b that extends in the direction in which the second shaft member 22 extends. In this embodiment, the plate material 13 constitutes a fire-resistant partition wall. The plate material 13 extends from the floor to the ceiling. The first plate portion 13a is provided with a plate insertion hole 13h. The plate insertion hole 13h penetrates the first plate portion 13a in the thickness direction.

[0057] The first plate 41 and the second plate 42 are inserted through the plate insertion hole 13h. The first plate 41 and the second plate 42 penetrate the first plate portion 13a. Within the plate insertion hole 13h are the portion of the first plate 41 located between the first through hole 41a and the second through hole 41b, and the portion of the second plate 42 located between the third through hole 42a and the fourth through hole 42b.

[0058] <Construction methods for building 10> The construction method for building 10 will be described below. The construction of building 10 will be carried out by workers. The construction method for building 10 includes a frame construction process for constructing the frame 11 and a brace construction process for connecting the braces 12 to the frame 11 using brace connecting members 14.

[0059] As described above, the brace connecting member 14 is temporarily connected to the shaft member 20 at the factory. The shaft member 20 is transported to the site with the brace connecting member 14 temporarily connected. In the frame construction process, the shaft member 20 is constructed with the brace connecting member 14 temporarily connected. In the brace construction process, the brace 12 is connected to the shaft member 20 by the brace connecting member 14 which is temporarily connected to the shaft member 20.

[0060] In this embodiment, the first plate 41 and the second plate 42 of the first brace connecting member 14a are temporarily connected to the first shaft member 21 so as not to protrude from the first shaft member 21 in a plan view. Furthermore, the first plate 41 and the second plate 42 of the first brace connecting member 14a are temporarily connected to the position where they will be permanently connected to the first shaft member 21 during the brace installation process. In this case, the brace installation process is carried out as follows.

[0061] First, the worker loosens the connection between the first shaft member 21 and the first plate 41 by the second bolt 16a and the second nut 16b, thereby allowing the first plate 41 to rotate around the second bolt 16a as the axis of rotation. Next, the worker loosens the connection between the first shaft member 21 and the second plate 42 by the third bolt 17a and the third nut 17b, thereby allowing the second plate 42 to rotate around the third bolt 17a as the axis of rotation.

[0062] Next, the worker rotates the first plate 41 around the second bolt 16a as the axis of rotation, and rotates the second plate 42 around the third bolt 17a as the axis of rotation. The first plate 41 and the second plate 42 are rotated so that the direction in which the first plate 41 extends and the direction in which the second plate 42 extends are in the desired direction, and the first through hole 41a and the third through hole 42a overlap in a plan view. After that, the worker permanently connects the first plate 41 to the first shaft member 21 by tightening the second bolt 16a, and permanently connects the second plate 42 to the first shaft member 21 by tightening the third bolt 17a.

[0063] Next, the worker positions the first brace 12a such that, in a plan view, the plate through-hole 34h of the first connecting plate 34a aligns with the first through-hole 41a and the third through-hole 42a. The worker adjusts the orientation of the first brace 12a so that the direction in which the brace body 30 extends is the desired direction. After that, the worker connects the first plate 41 and the second plate 42 to the first brace 12a by fastening the first nut 15b to the first bolt 15a inserted through the plate through-hole 34h, the first through-hole 41a, and the third through-hole 42a.

[0064] As a result, the first end of the first brace 12a is connected to the first shaft member 21 via the first brace connecting member 14a. Note that the final connection work of the first plate 41 and the second plate 42 to the first shaft member 21 and the connection work of the first plate 41 and the second plate 42 to the first brace 12a may be performed together after the direction in which the brace body 30, the first plate 41, and the second plate 42 extend has been adjusted.

[0065] [Operation of this embodiment] The operation of this embodiment will now be explained. The building 10 comprises a frame 11, braces 12, and brace connecting members 14. The frame 11 is composed of a plurality of axial members 20. The frame 11 is provided with a plurality of connecting holes 20h. The brace 12 has a rod-shaped brace body 30 and connecting plates 34 provided at both ends of the brace body 30. The connecting plates 34 are provided with plate through holes 34h. The brace connecting members 14 connect the brace 12 to the frame 11.

[0066] The brace connecting member 14 has a first plate 41 and a second plate 42. The first plate 41 is provided with a first through hole 41a and a second through hole 41b extending in the same direction as the first through hole 41a. The second plate 42 is provided with a third through hole 42a and a fourth through hole 42b extending in the same direction as the third through hole 42a.

[0067] The first plate 41 and the second plate 42 are connected to the brace 12 by first bolts 15a inserted through plate through holes 34h, the first through hole 41a, and the third through hole 42a. The first plate 41 is connected to the frame 11 by second bolts 16a inserted through connecting holes 20h and the second through hole 41b. The second plate 42 is connected to the frame 11 by third bolts 17a inserted through a different connecting hole 20h and a fourth through hole 42b, which are different from the connecting hole 20h through which the second bolts 16a are inserted.

[0068] With this configuration, when the connection between the connecting plate 34, the first plate 41, and the second plate 42 by the first bolt 15a is loosened, the first plate 41 and the second plate 42 are each rotatable relative to the connecting plate 34 with the first bolt 15a as the axis of rotation. Therefore, the direction in which the first plate 41 and the second plate 42 extend can be adjusted. This allows the brace connecting member 14 to be connected to the frame 11 in such a way that it does not interfere with other members connected to the frame 11.

[0069] Furthermore, the connecting hole 20h through which the second bolt 16a is inserted is different from the connecting hole 20h through which the third bolt 17a is inserted. In other words, the connection position of the first plate 41 to the frame 11 is different from the connection position of the second plate 42 to the frame 11. Therefore, the brace connecting member 14 can be stably connected to the frame 11. Consequently, the brace 12 can be suitably connected to the frame 11.

[0070] [Effects of this embodiment] The effects of this embodiment will now be explained. (1) The brace connecting member 14 has a first plate 41 and a second plate 42. The first plate 41 is provided with a first through hole 41a and a second through hole 41b extending in the same direction as the first through hole 41a. The second plate 42 is provided with a third through hole 42a and a fourth through hole 42b extending in the same direction as the third through hole 42a.

[0071] The first plate 41 and the second plate 42 are connected to the brace 12 by first bolts 15a inserted through plate through holes 34h, the first through hole 41a, and the third through hole 42a. The first plate 41 is connected to the frame 11 by second bolts 16a inserted through connecting holes 20h and the second through hole 41b. The second plate 42 is connected to the frame 11 by third bolts 17a inserted through a different connecting hole 20h and a fourth through hole 42b, which are different from the connecting hole 20h through which the second bolts 16a are inserted.

[0072] With this configuration, the brace connecting member 14 can be connected to the frame 11 in such a way that it does not interfere with other members connected to the frame 11. Furthermore, the brace connecting member 14 can be stably connected to the frame 11. Therefore, the brace 12 can be suitably connected to the frame 11.

[0073] (2) The plurality of shaft members 20 include a first shaft member 21. The plurality of connecting holes 20h include a plurality of first connecting holes 21h provided in the first shaft member 21. The first plate 41 is connected to the first shaft member 21 by second bolts 16a inserted through the first connecting holes 21h and second through holes 41b. The second plate 42 is connected to the first shaft member 21 by third bolts 17a inserted through a first connecting hole 21h different from the first connecting hole 21h through which the second bolts 16a are inserted, and through a fourth through hole 42b.

[0074] This configuration allows the brace 12 to be connected to different positions on the same shaft member 20. For example, if the frame 11 does not have an intersection where two shaft members 20 intersect, or if other members are connected to the intersection, the brace 12 can be connected to the frame 11.

[0075] (3) The angle between the reference line L extending in the direction in which the first shaft member 21 extends and the first virtual line L1 extending in the direction in which the brace body 30 extends is the first angle A1. The angle between the second virtual line L2 connecting the first through hole 41a and the second through hole 41b of the first plate 41 and the reference line L is the second angle A2. The angle between the third virtual line L3 connecting the third through hole 42a and the fourth through hole 42b of the second plate 42 and the reference line L is the third angle A3. The second angle A2 and the third angle A3 are both greater than the first angle A1.

[0076] The building 10 includes a plate member 13 that extends in the direction in which the first axial member 21 extends. The plate member 13 is provided with plate insertion holes 13h through which the first plate 41 and the second plate 42 are inserted.

[0077] With this configuration, compared to the case where the brace 12 is directly connected to the first shaft member 21 and a brace insertion hole is provided in the plate material 13 through which the brace 12 is inserted, the amount of material missing from the plate material 13 in the direction in which the first shaft member 21 extends can be reduced.

[0078] More specifically, the closer the angle between the direction in which the plate material 13 extends and the direction in which the member penetrating the plate material 13 extends is to 90 degrees, the smaller the size of the insertion hole in the plate material 13 in the direction in which the plate material 13 extends can be, thereby reducing the amount of material loss in the plate material 13. In other words, the closer the angle at which the member penetrating the plate material 13 penetrates the plate material 13 is to 90 degrees with respect to the direction in which the plate material 13 extends, the smaller the amount of material loss in the plate material 13 becomes.

[0079] According to the above configuration, the second angle A2 and the third angle A3 are each larger than the first angle A1. Therefore, the angle between the direction in which the plate material 13 extends and the direction in which the first plate 41 and the second plate 42 extend is closer to 90 degrees than the angle between the direction in which the plate material 13 extends and the direction in which the brace body 30 extends. In other words, the first plate 41 and the second plate 42 penetrate the plate material 13 at an angle closer to 90 degrees with respect to the direction in which the plate material 13 extends than when the brace 12 is directly connected to the first shaft member 21. Therefore, the amount of material missing from the plate material 13 can be reduced.

[0080] (4) The construction method of the building 10 includes a frame construction step of constructing a shaft member 20 to which a brace connecting member 14 is temporarily connected, and a brace construction step of connecting a brace 12 to the shaft member 20 using a brace connecting member 14 that is temporarily connected to the shaft member 20.

[0081] According to this method, since the brace connecting member 14 is pre-connected to the shaft member 20, it is possible to suppress the possibility of missing parts during installation of the brace 12. (5) The brace connecting member 14 is temporarily connected to the shaft member 20 so as not to protrude from the shaft member 20. This prevents the brace connecting member 14 from getting in the way when transporting or installing the shaft member 20.

[0082] (6) The brace connecting member 14 is temporarily connected to the shaft member 20 in the position where it will be permanently connected during the brace installation process. This allows the brace installation process to be carried out without removing the brace connecting member 14 that is temporarily connected to the shaft member 20.

[0083] (7) The second through hole 41b extends in the same direction as the first through hole 41a. The fourth through hole 42b extends in the same direction as the third through hole 42a. This makes it possible to accommodate both cases where the first plate 41 and the second plate 42 are connected to different positions on the same shaft member 20, and cases where they are connected to different shaft members 20, as will be described later.

[0084] (8) The first plate 41 and the second plate 42 are rotatable individually with respect to the connecting plate 34 with the first bolt 15a as the axis of rotation. This allows the brace connecting member 14 to be connected to a desired position on the shaft member 20 by adjusting the angle between the first plate 41 and the second plate 42, even if the multiple connecting holes 20h provided in the shaft member 20 are not arranged at equal intervals.

[0085] (9) As described above, by adjusting the direction in which the first plate 41 extends and the direction in which the second plate 42 extends, the brace connecting member 14 can be connected to the frame 11 in such a way that it does not interfere with other members connected to the frame 11. For this reason, in this embodiment, there are fewer restrictions on the connection position of the brace 12 to the frame 11. Accordingly, the two braces 12 can be connected to the frame 11 in such a way that the turnbuckles 33 of the two intersecting braces 12 within the frame 11a do not interfere with each other.

[0086] When the area of ​​the frame 11a is small and the connection position of the brace 12 to the frame 11 is far from the intersection of the shaft members 20, the turnbuckles 33 of the two braces 12 are likely to interfere with each other. In this embodiment, the connection position of the brace connecting member 14 to the frame 11 can be set close to the intersection of the shaft members 20, so that interference between the turnbuckles 33 of the two braces 12 can be suppressed when the area of ​​the frame 11a is small.

[0087] (10) When the brace 12 is directly connected to the frame 11, the direction in which the brace body 30 extends is determined by the connection position of the brace 12 to the frame 11. In contrast, in this embodiment, the first plate 41 and the second plate 42 are each rotatable with respect to the connecting plate 34 with respect to the first bolt 15a as the axis of rotation. In this case, the direction in which the brace body 30 extends is not determined by the connection positions of the first plate 41 and the second plate 42 to the frame 11, thus increasing the degree of freedom in the direction in which the brace body 30 extends.

[0088] <Example of changes> The above embodiment is an example of possible forms for the building 10, the construction method for the building 10, and the brace connecting member 14, and is not intended to limit their forms. The building 10, the construction method for the building 10, and the brace connecting member 14 may take forms different from those exemplified in the above embodiment. Examples of such forms include forms in which some of the configurations of the embodiment are replaced, modified, or omitted, or forms in which new configurations are added to the embodiment. Examples of modifications to the embodiment are shown below.

[0089] The shaft member 20 is not limited to being made of steel. The shaft member 20 may also be made of wood. In the above embodiment, the first axis member 21, the second axis member 22, the third axis member 23, and the fourth axis member 24 were horizontal members extending in the horizontal direction, but the embodiment is not limited to this. For example, the first axis member 21 and the third axis member 23 may be horizontal members extending in the horizontal direction, while the second axis member 22 and the fourth axis member 24 may be columns extending in the vertical direction. In this case, the first brace 12a and the second brace 12b are vertical braces.

[0090] The frame 11 does not necessarily have a frame 11a composed of four shaft members 20. The frame 11 may have two shaft members 20 extending in parallel. In this case, the frame 11 does not have an intersection where the two shaft members 20 intersect. Therefore, the first plate 41 and the second plate 42 are connected to different positions on the same shaft member 20.

[0091] In the above embodiment, both ends of the first brace 12a were connected to the frame 11 via the brace connecting member 14, but the embodiment is not limited to this. One end of the first brace 12a may be connected to the frame 11 via the brace connecting member 14, while the other end of the first brace 12a may be connected directly to the frame 11 without the brace connecting member 14.

[0092] In the above embodiment, both ends of the second brace 12b were connected to the frame 11 via the brace connecting member 14, but this is not limited to this. One end of the second brace 12b may be connected to the frame 11 via the brace connecting member 14, while the other end of the second brace 12b may be directly connected to the frame 11 without the brace connecting member 14.

[0093] In the above embodiment, the first plate 41 and the second plate 42 were connected to different positions on the same shaft member 20, but they may be connected to different shaft members 20. As shown in Figure 5, the first end of the first brace 12a is connected to the first shaft member 21 and the second shaft member 22 via the first brace connecting member 14a. The second end of the first brace 12a is connected to the third shaft member 23 and the fourth shaft member 24 via the second brace connecting member 14b. The first end of the second brace 12b is connected to the second shaft member 22 and the third shaft member 23 via the third brace connecting member 14c. The second end of the second brace 12b is connected to the first shaft member 21 and the fourth shaft member 24 via the fourth brace connecting member 14d.

[0094] The first plate 41 of the first brace connecting member 14a is positioned on top of the lower flange 27 of the first shaft member 21 such that the second through hole 41b communicates with the first connecting hole 21h of the first shaft member 21. The first plate 41 is connected to the first shaft member 21 by a second bolt 16a (not shown) being fastened to the second bolt 16a inserted through the second through hole 41b and the first connecting hole 21h.

[0095] The second plate 42 of the first brace connecting member 14a is positioned on top of the lower flange 27 of the second shaft member 22 such that the fourth through hole 42b communicates with the second connecting hole 22h of the second shaft member 22. The second plate 42 is connected to the second shaft member 22 by a third nut (not shown) being locked onto a third bolt 17a inserted through the fourth through hole 42b and the second connecting hole 22h.

[0096] With this configuration, the first end of the first brace 12a can be connected to the intersection where the first shaft member 21 and the second shaft member 22 intersect using the first brace connecting member 14a. The shapes of the first plate 41 and the second plate 42 may be changed as appropriate. Preferably, the shape of the first plate 41 is such that it does not interfere with the web 25 when the first plate 41 is rotated around the second bolt 16a as the axis of rotation. Preferably, the shape of the second plate 42 is such that it does not interfere with the web 25 when the second plate 42 is rotated around the third bolt 17a as the axis of rotation.

[0097] In the above embodiment, the connecting plate 34 was located above the first plate 41 and the second plate 42, but it may also be located below the first plate 41 and the second plate 42.

[0098] The brace connecting member 14 does not need to be temporarily connected to the shaft member 20 at the factory. In this case, the frame construction process is carried out with the brace connecting member 14 not temporarily connected to the shaft member 20.

[0099] The brace connecting member 14 may be temporarily connected to a position different from the position where it is permanently connected to the shaft member 20 during the brace installation process. In this case, during the brace installation process, the brace connecting member 14 is removed from the shaft member 20 and then permanently connected to the desired position on the shaft member 20. Even in this case, the effect (4) of the above embodiment can be obtained.

[0100] In this modified example, the first plate 41 and the second plate 42 of the brace connecting member 14 may be connected to the connecting plate 34 of the brace 12 and then to the frame 11. The brace connecting member 14 may protrude from the shaft member 20 when it is temporarily connected to the shaft member 20. Even in this case, the effect (4) of the above embodiment can be obtained.

[0101] When the first plate 41 and the second plate 42 are connected to different positions on the same shaft member 20, one of the second angle A2 and the third angle A3 may be the same as the first angle A1.

[0102] The first bolt 15a, the second bolt 16a, and the third bolt 17a are not limited to bolts having a shaft and a head. The first bolt 15a, the second bolt 16a, and the third bolt 17a may be, for example, threaded rods.
