[0008] An embodiment of the joining member will be described below with reference to Figures 1 to 4. Here, the joining member will be described as a member for attaching a second beam, which is an attached member, to a first beam.

[0009] Fig. 1 is a front view of the entire building in which the joining member is used, and Fig. 2 is an enlarged front view of the main part in Fig. 1. Fig. 3 and Fig. 4 are a top view and a side view, respectively, explaining the first beam and the second beam joined using the joining member. Here, in Fig. 3, for ease of viewing, a part of the right side of the second beam and the web of the first beam further to the right of that are shown in a cutaway state.

[0010] As shown in FIG. 1, one side of the building 10 is covered with a plurality of exterior materials 55. 2, each exterior material 55 is made up of a long, narrow rectangular plate member. The upper and lower ends of the exterior material 55 are attached to the second beam 50 extending horizontally.

[0011] 3 and 4, the second beam 50 of this embodiment is attached to the first beam 15 via a connecting member 20. The first beam 15 is supported by being connected to the skeleton (not shown) of the building 10.

[0012] The first beam 15 is made of an H-shaped steel with a sloped lower surface. The first beam 15 includes an upper flange 15a, a lower flange 15b, and a web 15w. The web 15w connects the upper flange 15a and the lower flange 15b.

[0013] Furthermore, the web 15w of the first beam 15 has a plurality of (four in this example) elongated holes 15h aligned in the vertical direction. These elongated holes 15h are provided at positions a predetermined distance away from the end of the first beam 15. This predetermined distance is the position where the second beam 50 is to be attached to the first beam 15 using the joining member 20. Each elongated hole 15h extends in the Y-axis direction and has a rounded rectangular shape with semicircular ends. These elongated holes 15h correspond to the third elongated holes.

[0014] Additionally, an attachment member 16 for attaching an upwardly extending member is welded to the upper flange 15a of the first beam 15. Furthermore, the lower end of an exterior material 55 is attached to the upper flange 50 a of the second beam 50 via an upper attachment portion 51 . Furthermore, the upper end of an exterior material 55 is attached to the lower flange 50b of the second beam 50 via a lower attachment portion 52.

[0015] (Configuration of joining member 20) Next, the joining member 20 according to the present invention will be described with reference to FIGS. The joining members 20 are arranged one on each side of the web 15w of the first beam 15 (two in total). The two joining members 20 arranged with the web 15w in between are configured to be line-symmetrical with the web 15w at the center. Furthermore, each joining member 20 supports an end of a second beam 50 different from the first beam 15 on the first beam 15.

[0016] As shown in FIGS. 3 and 4, the joining member 20 includes a first adjusting member 30 and a second adjusting member 40. The first adjustment member 30 includes a first surface portion 31 serving as a first adjustment plate and a second surface portion 32 serving as a second adjustment plate.

[0017] The first surface portion 31 is a plate-shaped member extending in the in-plane direction of the web 15w of the first beam 15, and is disposed along the web 15w of the first beam 15. Here, the in-plane direction of the web 15w refers to the extending direction of the web 15w, which in this embodiment refers to the direction in which the web 15w extends in the axial direction (Y-axis direction) and vertical direction (Z-axis direction) of the first beam 15. The second surface portion 32 is a plate-shaped member that extends in an out-of-plane direction of the web 15w of the first beam 15 and has a shorter vertical length than the first surface portion 31. Here, the out-of-plane direction of the web 15w refers to a plane direction perpendicular to the in-plane direction of the web 15w, and in this embodiment, refers to a direction extending in the axial width direction (X-axis direction) and vertical direction of the first beam 15. One side of this second surface portion 32 is welded to the first surface portion 31 near the tip end side of the first surface portion 31. Therefore, the first adjustment member 30 has a substantially L-shaped horizontal cross section. In this embodiment, the Z-axis direction corresponds to the first axis direction, the X-axis direction corresponds to the second axis direction, and the Y-axis direction corresponds to the third axis direction.

[0018] The first surface portion 31 has a plurality of (four in this example) elongated holes 31h arranged in a vertical line. These elongated holes 31h are provided at positions that correspond one-to-one to the elongated holes 15h of the first beam 15. Each elongated hole 31h extends in the Z-axis direction and has a rounded rectangular shape with semicircular ends. These elongated holes 31h correspond to the first elongated holes.

[0019] Nuts N1 are threaded onto bolts B1 that pass through the elongated holes 31h of the two first surface portions 31 and the elongated holes 15h of the webs 15w of the first beam 15 while they are aligned. Thus, a first adjustment member 30 of each connecting member 20 is attached to the first beam 15 on both sides of the web 15w, sandwiching the web 15w therebetween. In this embodiment, an adjustment unit AP1 that adjusts the relative position in the third axis direction (Y axis direction) is composed of the elongated holes 15h, 31h, bolts B1, and nuts N1. The adjustment unit AP1 is not limited to this configuration and may have other configurations as long as it is a member configured to adjust the relative position in the third axis direction, which is perpendicular to the first axis direction and the second axis direction. In this embodiment, one bolt B1 and one nut N1 are commonly used in the adjustment units AP1 of the two connecting members 20.

[0020] A plurality of (four in this example) elongated holes 32h are provided in a vertical row on the second surface portion 32. Each elongated hole 32h extends in the X-axis direction and is large enough to allow the shank of the bolt B2 to be inserted therein and move in the X-axis direction. These elongated holes 32h correspond to the second elongated holes.

[0021] The second adjustment member 40 of the joining member 20 includes a gusset plate portion 41 as a plate portion and a contact surface portion 45. The gusset plate portion 41 is a horizontally T-shaped plate member. The gusset plate portion 41 has a beam joint portion 41a that joins to the second beam 50 and a protruding portion 41b that is shorter in the vertical direction than the beam joint portion 41a. The beam joint portion 41a of the gusset plate portion 41 is welded to the web 50w, upper flange 50a, and lower flange 50b of the second beam 50. The protruding portion 41b of the gusset plate portion 41 protrudes toward the interior side (the opposite side from the exterior material 55). The end of the abutment surface portion 45 is welded to the tip of this protruding portion 41b.

[0022] The contact surface portion 45 has a plate shape that is slightly larger than the protruding portion 41b of the gusset plate portion 41, and is a plate-shaped member that contacts the second surface portion 32 of the first adjustment member 30. This contact surface portion 45 has a plurality of (four in this case) round holes 45h that are aligned in a vertical direction. Each hole 45h is provided at a position corresponding to each elongated hole 32h of the second surface portion 32 of the first adjustment member 30.

[0023] Then, the nuts N2 are screwed onto the bolts B2 that have passed through with the holes 45h aligned with the elongated holes 32h of the first adjustment member 30. This attaches the second adjustment member 40 of the joining member 20 to the first adjustment member 30 of the joining member 20.

[0024] (Method of constructing second beam 50 using joining member 20) Next, an example of a method for constructing the second beam 50 using the joint member 20 having the above-described configuration will be described.

[0025] First, the first beam 15 is attached to the skeleton of the building 10. A long hole 15h is formed in advance in this first beam 15. In addition, the end of the beam joint 41a of the second adjustment member 40 is welded to the upper flange 50a, the lower flange 50b, and the web 50w of the second beam 50.

[0026] Next, the first adjustment members 30 of the two connecting members 20 are placed across the web 15w of the first beam 15. Then, the first surface portion 31 of the first adjustment member 30 of each connecting member 20 is brought into contact with the web 15w, and then the elongated hole 31h of the first adjustment member 30 is aligned with the elongated hole 15h of the web 15w. Furthermore, the bolt B1 is inserted through the aligned elongated holes 31h, 15h and the nut N1 is screwed in, thereby temporarily fixing the members together.

[0027] Next, the abutment surface 45 of the second adjustment member 40 is abutted against the second surface 32 of the first adjustment member 30 of the joining member 20, and then the elongated hole 32h of the first adjustment member 30 is aligned with the hole 45h of the second adjustment member 40. Then, the bolt B2 is inserted through the aligned elongated hole 32h and hole 45h, and the nut N2 is screwed in, thereby temporarily fixing the first beam 15 to the second beam 50. In this way, the second beam 50 is temporarily fixed to the first beam 15 by the joining member 20.

[0028] Thereafter, the position of the hole 45h in the X-axis direction relative to the elongated hole 32h that was temporarily fixed by the bolt B2 is adjusted. Then, by tightening the bolt B2 and the nut N2 at the adjusted position, the position of the second beam 50 in the X-axis direction relative to the first beam 15 is adjusted and fixed.

[0029] Furthermore, after adjusting the positions of the elongated holes 31h in the Y-axis direction and the Z-axis direction relative to the elongated holes 15h that were temporarily fixed by the bolts B1, the bolts B1 and nuts N1 are tightened. As a result, the positions of the second beam 50 in the Y-axis direction and the Z-axis direction relative to the first beam 15 are adjusted and fixed.

[0030] (Operation of the embodiment) The elongated holes 15h and 31h allow adjustment of the relative positions in the Y-axis direction and the Z-axis direction between the first beam 15 and the first adjustment member 30. Furthermore, the elongated hole 32h allows adjustment of the relative positions in the X-axis direction between the first adjustment member 30 and the second adjustment member 40.

[0031] (Effects of the embodiment) (1) In this embodiment, the joining member 20 includes a first adjustment member 30 having a first surface portion 31 and a second surface portion 32, and a second adjustment member 40 welded to a second beam 50 and having an abutment surface portion 45. The first surface portion 31 has a slot 31h extending in the Z-axis direction, which corresponds to the slot 15h formed in the web 15w of the first beam 15 and extending in the Y-axis direction. The second surface portion 32 has a slot 32h extending in the X-axis direction, which corresponds to the hole 45h of the second adjustment member 40. The slots 15h and 31h are used to adjust the relative positions of the first beam 15 and the first adjustment member 30 in the Y-axis direction and the Z-axis direction, and the slot 32h is used to adjust the relative position of the first adjustment member 30 and the second adjustment member 40 in the X-axis direction. This allows the relative position of the second beam 50 with respect to the first beam 15 in each of the three axial directions (X-axis direction, Y-axis direction, and Z-axis direction) to be individually fine-tuned, thereby allowing the position in the three axial directions to be adjusted efficiently.

[0032] (2) In the present embodiment, the position of the joining member 20 in the X-axis direction is adjusted using the elongated hole 32h extending in the X-axis direction, the position of the joining member 20 in the Y-axis direction is adjusted using the elongated hole 15h extending in the Y-axis direction, and the position of the joining member 20 in the Z-axis direction is adjusted using the elongated hole 31h extending in the Z-axis direction. Therefore, the position in each direction can be adjusted individually.

[0033] (3) In this embodiment, two connecting members 20 are arranged on either side of the web 15w of the first beam 15. Then, one bolt B1 is passed through the long hole 31h of the first adjustment member 30 of the two connecting members 20 and fixed with a nut N1. This allows two second beams 50 to be attached to one first beam 15 while their positions in three axial directions are adjustable.

[0034] (4) The joining member 20 of this embodiment adjusts the Y-axis direction using the elongated hole 15h extending in the Y-axis direction. Because the length of the first beam 15 in the Y-axis direction is longer than the length of the first adjustment member 30 of the joining member 20 in the Y-axis direction, defects due to stress generated around the elongated hole 15h formed in the Y-axis direction are unlikely to occur.

[0035] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. In the above embodiment, the position of the joining member 20 in the Y-axis direction is adjusted by adjusting the relative position of the first surface portion 31 of the first adjustment member 30 with respect to the first beam 15. The joining member 20 may have multiple locations for adjustment in the same axial direction.

[0036] For example, as a modified example of the above embodiment, as shown in Figures 5 and 6, the end of one second beam 50 may be fixed to one side of the web 15w of the first beam 15 via the above-mentioned joining member 20, and another second beam 56 may be attached to the other side of the web 15w via a joining member 70.

[0037] 5 and 6, the second beam 56 extends in the same axial direction as the second beam 50, but is rotated 90 degrees. The second beam 56 is made of an H-shaped steel with a web 56w connecting two flanges 56f. The second beam 56 also has a horizontal gusset plate 56a. The horizontal gusset plate 56a is disposed between the pair of spaced-apart flanges 56f.

[0038] The joining member 70 includes a first adjusting member 80 and a second adjusting member 90. The first adjustment member 80 includes a first surface 81 serving as a first adjustment plate, a second surface 82 serving as a second adjustment plate extending horizontally, and a third surface 83 extending vertically. Similar to the first surface 31 of the first embodiment, the first surface 81 is a plate-shaped member extending in the axial direction (Y-axis direction) and vertical direction (Z-axis direction) of the first beam 15, and is disposed along the web 15w of the first beam 15. Similar to the first surface 31, the first surface 81 is provided with a plurality of (here, four) elongated holes 81h aligned in a row at positions corresponding to the elongated holes 15h of the first beam 15 in the vertical direction. Each elongated hole 81h extends in the Z-axis direction and has a rounded rectangular shape with semicircular ends. Then, the bolt B3 is inserted with the elongated hole 31h of the first surface portion 31 of the connecting member 20, the elongated hole 15h of the web 15w, and the elongated hole 81h of the first surface portion 81 of the connecting member 70 aligned, and the nut N3 threaded onto the bolt B3 is tightened. As a result, similar to the above embodiment, the second beams 50, 56 are fixed to the first beam 15 while their positions in the Z-axis direction and the Y-axis direction are adjusted. In this connecting member 70, the adjustment unit AP2 that adjusts the relative position in the third axis direction (Y-axis direction) is composed of the elongated hole 81h, the elongated hole 15h, the bolt B3, and the nut N3. The adjustment unit AP2 is not limited to this configuration and may have other configurations as long as it is a member configured to adjust the relative position in the third axis direction perpendicular to the first axis direction and the second axis direction. In this configuration, one bolt B3 and one nut N3 are commonly used for the adjustment unit AP1 of the connecting member 20 and the adjustment unit AP2 of the connecting member 70.

[0039] The second surface portion 82 extends in the horizontal direction (X-axis direction and Y-axis direction) of the first beam 15, and one side portion thereof is welded to the center portion of the first surface portion 81. A plurality of (four in this case) elongated holes 82h are formed on the second beam 56 side of this second surface portion 82. Each elongated hole 82h is a hole that extends in the X-axis direction and corresponds to a second elongated hole.

[0040] Furthermore, the third surface portion 83 is disposed so as to extend in the vertical direction perpendicular to the second surface portion 82, and is welded to the lower surface of the second surface portion 82 and the first surface portion 81. This third surface portion 83 is disposed so as to be in the same vertical plane as the second surface portion 32 of the first adjustment member 30 of the joining member 20.

[0041] The second adjustment member 90 includes a gusset plate portion 91 and an abutment surface portion 95. The gusset plate portion 91 has a beam joint portion 91a and a protrusion portion 91b. The beam joint portion 91a is provided in the same plane as the horizontal gusset plate 56a of the second beam 56 and is welded to the outside of the flange 56f. The protrusion portion 91b is disposed so as to be perpendicular to the beam joint portion 91a. The lower surface of the protrusion portion 91b is flush with the beam joint portion 91a.

[0042] The contact surface 95 of the second adjustment member 90 extends horizontally and is welded to the lower surfaces of the beam joint 91a and the protrusion 91b. The contact surface 95 is placed on the upper surface of the second surface 82 of the first adjustment member 80. The contact surface 95 has multiple (four) elongated holes 95h that correspond to the elongated holes 82h of the second surface 82. Each elongated hole 95h extends in the Y-axis direction. This elongated hole 95h corresponds to the fourth elongated hole.

[0043] Then, with the elongated holes 82h and 95h aligned, the bolt B4 is inserted and the nut N4 threaded onto the bolt B4 is tightened. Therefore, by changing the relative position of the elongated hole 82h of the first adjustment member 80 with respect to the elongated hole 95h of the abutment surface portion 95 of the second adjustment member 90, the positions in the X-axis and Y-axis directions can be adjusted. Furthermore, in this joining member 70, the position in the Y-axis direction is adjusted by changing the relative position of the first surface 81 of the first adjustment member 80 with respect to the web 15w, and by changing the relative position of the abutment surface 95 of the second adjustment member 90 with respect to the second surface 82. This allows for a wide adjustment range of the position in the Y-axis direction. Furthermore, in the joining member 70, the third surface portion 83 of the first adjusting member 80 and the protruding portion 91b of the second adjusting member 90 may be omitted.

[0044] In the above embodiment, two connecting members 20 are attached that are configured symmetrically about the web 15w of the first beam 15. The connecting members 20 attached to the first beam 15 are not limited to two connecting members 20 that are configured symmetrically about the web 15w. For example, two connecting members may be arranged in which the lengths of the first surface portion 81 or the gusset plate portion 41 in the Y-axis direction are different.

[0045] In the above embodiment, the ends of two different second beams 50 are attached to the first beam 15 via two connecting members 20. However, one second beam 50 may be attached to the first beam 15 via one connecting member 20.

[0046] In the above embodiment, the web 15w of the first beam 15 is provided with elongated holes 15h extending in the Y-axis direction, and the first adjustment member 30 is provided with elongated holes 31h extending in the Z-axis direction corresponding to each elongated hole 15h. However, the extension direction of the elongated holes used for position adjustment is not limited to this; for example, the extension direction of the elongated holes may be reversed. For example, the web 15w may be provided with elongated holes extending in the Z-axis direction, and the first surface portion of the first adjustment member 30 may be provided with elongated holes extending in the Y-axis direction. Alternatively, the elongated holes 32h formed in the second surface portion 32 of the first adjustment member 30 and extending in the X-axis direction may be circular holes, and the holes 45h in the contact surface portion 45 of the second adjustment member 40 may be elongated holes extending in the X-axis direction.

[0047] In the above embodiment, the second beams 50, 56 are attached to the first beam 15 using the joining members 20, 70. The members (attached members) to be attached using the joining members are not limited to the second beams 50, 56, and may be other members. In the above embodiment, the first beam 15 is configured as an H-shaped steel beam with an inclined lower surface. The first beam is not limited to this shape, and may be any beam with a shape that includes a web to which the first adjustment member of the joining member is attached.
