The outer diameter of the nut 32 is designed to be large enough to exceed the width of each of the slits 24 and 29.

[0019] (Example of attaching a sandbag hanging bracket to a beam) An example of the work of attaching the sandbag hanging bracket 10 to the beam 12 is as follows. The beam 12 is fixed to the building, and the flange 12A of the beam 12 is positioned below the flange 12B in the vertical direction C1. Then, as shown in Figures 4A and 4B, the first hanger base 15 and the second hanger base 16 are respectively positioned on both sides of the beam 12 in the width direction C2. The engaging portion 20 is positioned above the support portion 22 in the vertical direction C1. The engaging portion 25 is positioned above the support portion 27 in the vertical direction C1. The tips of the engaging portions 20 and 25 are directed toward the beam 12. The engaging portions 20 and 25 are positioned at the same height in the vertical direction C1. The support portion 27 is positioned below the support portion 22 in the vertical direction C1.

[0020] Furthermore, the first hanger base 15 and the second hanger base 16 are brought closer to the beam 12. Then, the engaging portion 20 is inserted between the flanges 12A and 12B, and the engaging portion 25 is inserted between the flanges 12A and 12B. The tip of the support portion 22 is inserted into the space A2. Thereafter, the first hanger base 15 and the second hanger base 16 are stopped, and the engaging portions 20 and 25 are placed on the flange 12A. When the first hanger base 15 and the second hanger base 16 are viewed from directly above in a plan view, the bolt insertion holes 23 and 28 are positioned with the common imaginary line B1 as their centers. When the first hanger base 15 and the second hanger base 16 are viewed from directly above in a plan view, the slits 24 and 29 are at the same position in the direction along the walls 21 and 26.

[0021] Then, the fixing bolt 17 is moved in the width direction C2 of the beam 12, and after the fixing bolt 17 is inserted into the bolt insertion holes 23, 28, the two nuts 30 are attached to the male threads of the fixing bolt 17 and rotated. The two nuts 30 are tightened, and the nuts 30 are pressed against the wall portion 21 and the wall portion 26. Then, when the tip of the engaging portion 20 is pressed against the web 12C and the tip of the engaging portion 25 is pressed against the web 12C, the tightening of the two nuts 30 is completed.

[0022] When the two nuts 30 are tightened, the first hanger base 15 and the second hanger base 16 are positioned and fixed in the width direction C2 of the beam 12. In addition, the support portion 22 and the support portion 27 are overlapped. The support portion 22 is located above the support portion 27 in the vertical direction C1. When the first hanger base 15 and the second hanger base 16 are viewed in plan from directly above in the vertical direction with the support portion 22 and the support portion 27 overlapping, the arrangement area of ​​the slit 24 and the arrangement area of ​​the slit 29 at least partially overlap.

[0023] Next, the two positioning bolts 18 are placed horizontally next to each other below the slits 29 below the second hanger base 16. The two positioning bolts 18 are then raised and inserted into the slits 24 and 29, respectively. Furthermore, nuts 31 are attached to the two positioning bolts 18, respectively, and the upper ends of the two positioning bolts 18 are brought into contact with the flange 12A, respectively. After that, the two nuts 31 are rotated so as to approach the support portion 22.

[0024] When the two nuts 31 are pressed against the support portion 22, the upper ends of the positioning bolts 18 are pressed against the lower surface of the flange 12A. When the two nuts 31 are pressed against the support portion 22, the engaging portion 20 is pressed against the upper surface of the flange 12A. Furthermore, the force pressing the nuts 31 against the support portion 22 is applied to the support portion 27, and the engaging portion 25 is pressed against the flange 12A. When the engaging portions 20 and 25 are pressed against the flange 12A in this way, the tightening of the two nuts 31 is completed. When the tightening of the two nuts 31 is completed, the first hanger base 15 and the second hanger base 16 are positioned and fixed in the vertical direction C1 relative to the beam 12.

[0025] Furthermore, the eyebolt 19 is positioned below the second hanger base 16, with the shaft 19B facing upward. Next, the eyebolt 19 is raised, and the shaft 19B enters the slits 29, 24, and then the eyebolt 19 is stopped. Furthermore, when the nut 32 is attached to the shaft 19B and tightened, the supports 22, 27 are sandwiched between the nut 32 and the ring 19A, and the supports 22, 27 are tightly attached, completing the tightening of the nut 32. In this way, the eyebolt 19 is fixed to the supports 22, 27.

[0026] The order of inserting positioning bolt 18 into slits 24, 29 and tightening nut 31 and the order of inserting eyebolt 19 into slits 24, 29 and tightening nut 32 can be reversed. After sandbag hanging bracket 10 is attached to beam 12, the worker hangs connector 14 on ring 19A, and sandbag 11 is suspended.

[0027] (Effects of this embodiment) By tightening two nuts 30 attached to the fixing bolts 17, the first hanger base 15 and the second hanger base 16 of the punching bag hanging bracket 10 are pressed against the beam 12 in the width direction C2. In other words, the first hanger base 15 and the second hanger base 16 sandwich the beam 12 from both sides in the horizontal direction, thereby positioning and fixing the punching bag hanging bracket 10 in the width direction C2 of the beam 12.

[0028] Furthermore, by tightening the two nuts 31, the upper end of the positioning bolt 18 and the engagement portions 20 and 25 are pressed against the flange 12A, and the sandbag hanging bracket 10 is positioned and fixed in the vertical direction C1 relative to the beam 12. Furthermore, the wall portion 21 protrudes downward from the engagement portion 20, and the wall portion 26 protrudes downward from the engagement portion 25. The support portion 22 extends horizontally from the wall portion 21, and the support portion 27 extends horizontally from the wall portion 26. Then, with the support portions 22 and 27 overlapping, the eyebolt 19 is fixed to the support portions 22 and 27. Furthermore, the sandbag 11 is hung from the eyebolt 19.

[0029] Therefore, in order to fix the sandbag hanging bracket 10 to the beam 12, it is not necessary to drill a bolt insertion hole in the beam 12 with a tool such as a drill. This simplifies the work of attaching the sandbag hanging bracket 10 to the beam 12. Also, since there is no need to form a bolt insertion hole in the beam 12, a decrease in the strength of the beam 12 is prevented. Furthermore, the load in the vertical direction C1 of the sandbag 11 hung from the eye bolt 19 is supported by the beam 12 via the nut 32, the first hanger base 15, and the second hanger base 16. This prevents the load in the vertical direction C1 of the sandbag 11 from being applied to the fixing bolt 17. Therefore, the fixing bolt 17 is not subjected to a bending load, and deformation and damage of the fixing bolt 17 can be prevented.

[0030] Furthermore, because the two positioning bolts 18 are inserted into the slits 24, 29, the two positioning bolts 18 can be stopped at any position in the longitudinal direction of the slits 24, 29. Furthermore, because the shank 19B of the eyebolt 19 is inserted into the slits 24, 29, the eyebolt 19 can be stopped at any position in the longitudinal direction of the slits 24, 29. Furthermore, the two positioning bolts 18 and the shank 19B are configured to be inserted into the common slits 24, 29. Therefore, it is not necessary to provide separate insertion holes for inserting the two positioning bolts 18 and for inserting the shank 19B, and this can prevent a decrease in the strength of the first hanger base 15 and the second hanger base 16.

[0031] Furthermore, by tightening the nut 31, the flange 12A is sandwiched between the tip of the positioning bolt 18 and the engagement portions 20, 25. Therefore, by adjusting the tightening amount of the nut 31, the first hanger base 15 and the second hanger base 16 can be attached to and detached from the beam 12 having different thicknesses in the vertical direction C1 of the flange 12A. Furthermore, by loosening the nut 30, the first hanger base 15 and the second hanger base 16 can be attached to and detached from the beam 12.
