[0010] (Embodiment) Hereinafter, embodiments of the single pipe joint and single pipe clamp of the present disclosure will be described with reference to the accompanying drawings. Note that the single pipe joint and single pipe clamp of the present disclosure are not limited to the configurations and methods described in the following embodiments.
[0011] FIG. 1 is a side view of a scaffolding structure 2 using a single pipe joint 4 and a single pipe clamp 6 according to an embodiment.
[0012] The scaffolding structure 2 constitutes a scaffold at a work site such as a building, bridge, or highway.
[0013] The scaffolding structure 2 shown in FIG. 1 comprises a single pipe joint 4, a single pipe clamp 6, a first single pipe 8, a second single pipe 10, a flanged support 12, and a chain 13.
[0014] The single pipe joint 4 is a member that connects the first single pipe 8 to the flanged support 12. The single pipe clamp 6 is a member that connects the second single pipe 10 to the flanged support 12. By using the single pipe joint 4 and the single pipe clamp 6, it is possible to combine single pipes and flanged support to build and expand scaffolding.
[0015] In the example shown in FIG. 1, the first single pipe 8 and the second single pipe 10 extend in the vertical direction, and the flanged support 12 extends in the horizontal direction.
[0016] The flanged support 12 is a support / single pipe having a plurality of flanges 14. The flanges 14 have a plurality of holes into which wedges can be inserted. By hooking a scaffolding plank with a hook (not shown) onto the horizontally arranged flanged support 12, a scaffold on which workers can work is constructed.
[0017] Chain 13 is a member for suspending flanged support 12. Chain 13 shown in Figure 1 connects first single pipe 8 and flanged support 12 so as to suspend flanged support 12 from first single pipe 8. A hook attached to the tip of chain 13 is hooked onto flange 14 of flanged support 12.
[0018] As shown in Figure 1, a first fastener 16 is used in the single pipe joint 4, and a second fastener 18 is used in the single pipe clamp 6. The first fastener 16 is a lock pin, and the second fastener 18 is a bolt. The first fastener 16 is not limited to a lock pin, and may be any other type of fastener.
[0019] (Single pipe joint) The single pipe joint 4 will be described with reference to FIGS. 2 to 6B.
[0020] FIG. 2 is a front view of the single pipe joint 4. FIG.
[0021] The single pipe joint 4 shown in FIG. 2 includes a cylindrical member 22 and a single clamp 24.
[0022] The cylindrical member 22 is a cylindrical member into which the flanged support 12 shown in Fig. 1 can be inserted. A plurality of through holes 26A, 26B for inserting the first fasteners 16 are provided on the side surface of the cylindrical member 22. By providing a plurality of through holes 26A, 26B, it is possible to accommodate various types of flanged support 12.
[0023] 2, two through holes 26A and 26B are provided at an interval in the axial direction X of the cylindrical member 22. The first through hole 26A closer to the single clamp 24 has a larger diameter than the second through hole 26B farther from the single clamp 24. Furthermore, the through holes 26A and 26B are positioned to overlap each other in the circumferential direction of the cylindrical member 22.
[0024] The tubular member 22 has a first end 32 and a second end 34. The flanged post 12 can be inserted into the first end 32, and the single clamp 24 is attached to the second end 34.
[0025] The single clamp 24 is a member capable of fixing the first single pipe 8 shown in Fig. 1. The single clamp 24 is not limited to a clamp for fixing a round pipe, but may also be a clamp for fixing a square pipe.
[0026] FIG. 3 is a plan view showing the first end 32 of the tubular member 22, and FIG. 4 is a plan view showing the second end 34.
[0027] As shown in FIG. 3, the first end 32 is provided with a first opening 36 through which the flanged post 12 can be inserted.
[0028] 4, the second end 34 is provided with a second opening 38. A bolt (not shown) for attaching the single clamp 24 is inserted into the second opening 38.
[0029] As shown in FIG. 5, when attaching the single clamp 24 (not shown) to the second end 34, a bolt 40 is inserted into the second opening 38 of the second end 34, and a nut 42 is inserted into the first opening 36 of the first end 32, and the nut 42 is engaged with the bolt 40 inside the tubular member 22.
[0030] By adjusting the engagement amount of the nut 42, the single clamp 24 can be attached to the cylindrical member 22 in a state in which it can rotate around the axial direction X of the cylindrical member 22.
[0031] A method for connecting the first single pipe 8 and the flanged support 12 using the single pipe joint 4 having the above-described configuration will be described with reference to FIGS. 6A and 6B.
[0032] As shown in FIG. 6A, a single pipe joint 4 and a flanged support 12 are prepared.
[0033] Although not shown in the drawings, the first single pipe 8 (not shown) is gripped by the single clamp 24 of the single pipe joint 4. The flanged support 12 is inserted into the single pipe joint 4 while gripping the first single pipe 8.
[0034] The flanged strut 12 has a main body portion 44 and a tip connecting portion 46. The tip connecting portion 46 is a tip portion for connecting the flanged strut 12 to another member (for example, another flanged strut), and has a smaller diameter than the main body portion 44. The tip connecting portion 46 is provided with a through-hole 48 into which the first fastener 16 can be inserted.
[0035] By inserting the tip connecting portion 46 into the first opening 36 of the first end 32, the state shown in FIG. 6B is achieved.
[0036] As shown in Figure 6B, the through hole 26B of the tubular member 22 and the through hole 48 of the flanged support 12 are aligned, allowing the first fastener 16 to be inserted. By inserting the first fastener 16 into the through holes 26B and 48, the flanged support 12 is fixed to the single pipe joint 4. In this way, the first single pipe 8 and the flanged support 12 are connected (Figure 1).
[0037] As mentioned above, the tubular member 22 and the single clamp 24 can rotate relative to each other, so when the flanged support 12 is inserted into the tubular member 22, the tubular member 22 can be rotated relative to the single clamp 24, making it easy to align the positions of the through hole 26B and the through hole 48.
[0038] The specifications of the flanged struts 12 vary depending on the manufacturer, resulting in different lengths of the tip connection portions 46 and different positions and sizes of the through holes 48. In the single pipe joint 4 of this embodiment, two through holes 26A, 26B are provided spaced apart in the axial direction X. This allows the through holes 26A, 26B to be used interchangeably, enabling the connection of a variety of flanged struts 12. The number, positions, and sizes of the through holes 26A, 26B may be changed as appropriate.
[0039] (Action / Effect 1) As described above, the single pipe joint 4 of this embodiment comprises a tubular member 22 having a first end 32 and a second end 34, into which a flanged support 12 can be inserted, and a single clamp 24 attached to the second end 34 of the tubular member 22, and through holes 26A, 26B are provided on the side of the tubular member 22 for positioning a first fixing device 16 that fixes the flanged support 12 inserted into the first end 32.
[0040] With this configuration, the flanged support 12 and the single pipe 8 can be easily connected, improving workability at the scaffolding.
[0041] Furthermore, in the single pipe joint 4 of the embodiment, the through holes 26A, 26B include a first through hole 26A and a second through hole 26B that are spaced apart in the axial direction X of the tubular member 22. This configuration can accommodate different types of flanged posts 12.
[0042] Furthermore, in the single pipe joint 4 of the embodiment, the first through hole 26A and the second through hole 26B have different diameters. With this configuration, it is possible to accommodate different types of flanged struts 12.
[0043] Furthermore, in the single pipe joint 4 of the embodiment, the first through hole 26A and the second through hole 26B are aligned with each other in the circumferential direction of the tubular member 22. This configuration makes it easier to grasp the orientation of the tubular member 22, improving workability.
[0044] Furthermore, in the single pipe joint 4 of the embodiment, a second opening 38 is provided at the second end 34 of the tubular member 22, into which a bolt 40 for attaching the single clamp 24 is inserted, and the single clamp 24 is rotatably attached to the tubular member 22 by engaging a nut 42 with the bolt 40 inserted into the second opening 38. With this configuration, the relative rotational positions of the tubular member 22 and the single clamp 24 can be adjusted, improving workability.
[0045] The single pipe clamp 6 will be described with reference to FIGS. 7 to 11C.

[0055] The two bolt receiving portions 54A, 54B are provided circumferentially of the cylindrical member 50 at an interval of 180 degrees.
[0056] As shown in FIG. 10 , when attaching the single clamp 52 (not shown) to the second end 58, a bolt 64 is inserted into the second opening 62 of the second end 58, and a nut 66 is inserted into the first opening 60 of the first end 56, and the nut 66 is engaged with the bolt 64 inside the tubular member 50.
[0057] By adjusting the engagement amount of the nut 66, the single clamp 52 can be attached to the cylindrical member 50 in a state in which it can rotate around the axial direction X of the cylindrical member 50.
[0058] A method for connecting flanged support 12 and second single pipe 10 using single pipe clamp 6 having the above configuration will be described with reference to FIGS. 11A to 11C.
[0059] As shown in FIG. 11A, a single pipe clamp 6 and a flanged support 12 are prepared.
[0060] The flanged support 12 has a tip portion 68, which is inserted into the tubular member 50 of the single pipe clamp 6. The tip portion 68 is the end opposite to the tip connection portion 46 shown in FIG. 6A and has the same diameter as the main body portion 44. A flange 14 is provided near the tip portion 68.
[0061] Inserting the tip 68 into the first opening 60 of the first end 56 results in the state shown in FIG. 11B.
[0062] 11B, flanged support 12 is inserted into tubular member 50, and bolt receiving portions 54A, 54B face flange 14 of flanged support 12. By aligning the positions of bolt receiving portions 54A, 54B and the through holes of flange 14, second fasteners 18A, 18B can be inserted into flange 14 and bolt receiving portions 54A, 54B.
[0063] As shown in Figure 11C, the flanged support 12 is fixed to the single pipe clamp 6 by the second fixing devices 18A and 18B. In this state, the second single pipe 10 is gripped by the single clamp 52, thereby connecting the second single pipe 10 and the flanged support 12 (Figure 1).
[0064] The specifications of flanged support posts 12 vary depending on the manufacturer, and the shape and position of the flange 14 vary slightly, but the single pipe clamp 6 of this embodiment can accommodate flanged support posts 12 of various specifications.
[0065] The number, positions and sizes of the bolt receiving portions 54A and 54B may be changed as appropriate.
