[Modes for carrying out the invention]

[0011] The embodiments of the scaffolding trolley and scaffolding of this disclosure will be described below with reference to the attached drawings. However, the scaffolding trolley and scaffolding of this disclosure are not limited to the configurations and methods described in the embodiments below.

[0012] (Embodiment) FIG. 1 is a perspective view of the scaffolding cart 2 according to the embodiment.

[0013] The scaffolding cart 2 shown in FIG. 1 is a member that constitutes a scaffolding for structures (not shown) such as buildings, bridges, and highways. The scaffolding cart 2 functions as a cart at the work site.

[0014] As shown in FIG. 1, the scaffolding cart 2 includes two cart members 4A and 4B, four connecting pipes 6, 8, 10, and 12, two connecting pipes 14A and 14B, and one scaffolding board 16 with a hook.

[0015] The cart members 4A and 4B are members that function as carts respectively. The cart members 4A and 4B have the same structure and may be collectively referred to as "cart member 4". Other members may also be referred to in the same way.

[0016] Each of the cart members 4 has a base pipe 18 (18A, 18B), two wheels 20 (20A, 20B), and two flanged struts 22 (22A, 22B).

[0017] The first cart member 4A has a first base pipe 18A, two first wheels 20A, and two first flanged struts 22A. The second cart member 4B has a second base pipe 18B, two second wheels 20B, and two second flanged struts 22B.

[0018] Each of the base pipes 18 is a pipe for attaching the wheels 20 and the flanged struts 22. The wheels 20 are attached to the lower surface of the base pipe 18, and the flanged struts 22 are attached to the upper surface of the base pipe 18.

[0019] Each of the wheels 20 is a pair of wheels that enables the cart member 4 to move. Each of the wheels 20 has a stopper.

[0020] The flange-equipped struts 22 are each strut members with a plurality of flanges 50 attached to a single pipe at predetermined intervals. In the example shown in FIG. 1, a plurality of flanges 50 are provided on each of the flange-equipped struts 22. Each flange 50 has a plurality of holes into which the wedges of the wedge-equipped pipes can be inserted.

[0021] The four connecting pipes 6, 8, 10, 12 are each pipes for connecting two bogie members 4A, 4B to each other. The connecting pipes 6, 8 are each wedge-equipped pipes and are fixed to the flanges 50A, 50B of the flange-equipped struts 22A, 22B. The connecting pipes 10, 12 are each pipes without wedges and are fixed to the base pipes 18A, 18B via clamps.

[0022] The connecting pipes 14 are each single pipes for connecting the flange-equipped struts to each other. The first connecting pipe 14A connects the two first flange-equipped struts 22A in the first bogie member 4A to each other, and the second connecting pipe 14B connects the two second flange-equipped struts 22B in the second bogie member 4B to each other.

[0023] The connecting pipes 14A, 14B are each wedge-equipped pipes and are fixed to the flanges 50A, 50B of the flange-equipped struts 22A, 22.

[0024] The staging board 16 with hooks is suspended between the two connecting pipes 14A, 14B.

[0025] The staging board 16 with hooks is a staging board having a plurality of hooks. The first hook of the staging board 16 with hooks is hung on the first connecting pipe 14A, and the second hook is hung on the second connecting pipe 14B. By providing the staging board 16 with hooks, the operator P can work while standing on the staging board 16 with hooks. When getting on the staging board 16 with hooks, the base pipe 18 can be used as a step.

[0026]

[0027] With the scaffolding trolley 2 having the above configuration, a worker P can easily move the scaffolding trolley 2 by holding the flanged support column 22, etc., and can fix it in a predetermined position by operating the stopper on the wheel 20. The fixed scaffolding trolley 2 can be used as a component of the scaffolding, and the worker P can perform work while standing on the scaffolding board 16 with hooks on the scaffolding trolley 2.

[0028] Figures 2 and 3 are schematic front views showing the trolley component 4, respectively.

[0029] As shown in Figure 2, the trolley member 4 further includes a support column mounting portion 24 (24A, 24B) and a pipe mounting portion 26 (26A, 26B).

[0030] Each of the column mounting sections 24 is a member for attaching the flanged column 22. The column mounting section 24 shown in Figure 2 is a rod-shaped member into which the end of the flanged column 22 can be inserted, and is erected on the upper surface of the base pipe 18. The first column mounting section 24A can be used to attach the first flanged column 22A on the first bogie member 4A, and the second column mounting section 24B can be used to attach the second flanged column 22B on the second bogie member 4B.

[0031] The support column mounting portion 24 is fixed to the base pipe 18, for example, via a clamp.

[0032] Each pipe mounting section 26 is a component for attaching the connecting pipes 10 and 12 shown in Figure 1. The pipe mounting section 26 is a rod-shaped member to which a clamp can be fixed, and the connecting pipes 10 and 12 are attached via the clamp as shown in Figure 3. The pipe mounting section 26 on the left side of the page can be used to attach the first connecting pipe 10, and the pipe mounting section 26 on the right side of the page can be used to attach the second connecting pipe 12.

[0033] The base pipes 18 shown in Figures 2 and 3 each have a lower pipe 28 and an upper pipe 30. The first base pipe 18A has a first lower pipe 28A and a first upper pipe 30A, and the second base pipe 18B has a second lower pipe 28B and a second upper pipe 30B.

[0034] The lower pipe 28 is a pipe that forms the lower surface of the base pipe 18, and the wheel 20 is attached to it. The upper pipe 30 is a pipe that forms the upper surface of the base pipe 18, and the support column mounting part 24 is attached to it. The lower pipe 28 and the upper pipe 30 are fixed to each other by means of welding, clamps, etc.

[0035] In this embodiment, the pipe mounting portion 26 is a rod-shaped member extending upward from the lower pipe 28 and is inserted into a through hole (not shown) in the upper pipe 30. Thus, the lower pipe 28 and the upper pipe 30 can be connected and fixed using the pipe mounting portion 26.

[0036] Figure 4 is a schematic perspective view showing an example of a scaffolding 1A assembled using multiple scaffolding trolleys 2.

[0037] The scaffolding 1A shown in Figure 4 is constructed by combining two scaffolding trolleys 2A and 2B. The two scaffolding trolleys 2A and 2B are connected to each other by multiple connecting pipes 32. Each connecting pipe 32 is a wedge-type pipe and is fixed to the flange 50 of the flanged support column 22.

[0038] In the example shown in Figure 4, three scaffolding boards 16 with hooks are installed at the same height. One scaffolding board 16 with hooks is provided on the first scaffolding trolley 2A, one scaffolding board 16 with hooks is provided on the second scaffolding trolley 2B, and one scaffolding board 16 with hooks is provided between the two trolleys 2A and 2B.

[0039] The scaffolding planks 16 with hooks, connecting pipes 14 and 32, and connecting pipes 6, 8, 10, and 12 can be attached at any position, offering a high degree of design flexibility. By providing the scaffolding planks 16 with hooks at multiple height positions, workers P can work at various heights.

[0040] In the example shown in Figure 4, worker P1 is climbing the first scaffolding trolley 2A, and worker P2 is standing on the hooked scaffolding board 16 of the second scaffolding trolley 2B. When worker P1 climbs the first scaffolding trolley 2A, he can use the base pipe 18 and connecting pipe 14 as a base and climb by holding onto the flanged support column 22 and connecting pipe 14 with his hands.

[0041] By connecting multiple scaffolding trolleys 2 horizontally, the scaffolding 1 can be expanded horizontally. When connecting the scaffolding trolleys 2 together, the connecting pipes 32 can be easily fixed to the flanges 50.

[0042] When expanding the scaffolding 1 in the height direction, for example, flanged support columns 22 can be connected to each other in the height direction. This allows for easy expansion in the height direction.

[0043] Figure 5 is a schematic perspective view showing an example of a scaffolding 1B assembled from multiple scaffolding trolleys 2.

[0044] The scaffolding 1B shown in Figure 5 is made up of a combination of numerous scaffolding trolleys 2, and further includes multiple support structures 32 and multiple staircases 34.

[0045] The support structure 32 is provided to firmly secure scaffolding 1B to the ground.

[0046] The stairs 34 are provided for workers to climb inside the scaffolding 1. In the example shown in Figure 5, multiple stairs 34 are provided at the connection point between two scaffolding trolleys 2. This allows workers to work at multiple heights using the stairs 34.

[0047] Figure 6 is a schematic perspective view showing an example of a scaffolding 1C assembled from multiple scaffolding trolleys 2.

[0048] The scaffolding 1C shown in Figure 6 is an extension of the scaffolding 1B shown in Figure 5, further combined with multiple scaffolding trolleys 2 to extend it laterally.

[0049] Scaffolding 1C, shown in Figure 6, is longer laterally and more stable than scaffolding 1B, shown in Figure 5, and therefore does not have bracing. This allows workers to work over a wider area.

[0050] With the scaffolding trolley 2 having the above configuration, it is possible to construct small-scale scaffolding 1A as shown in Figure 4, and large-scale scaffolding 1B and 1C as shown in Figures 5 and 6, making it possible to construct various types of scaffolding 1. Assembly and disassembly of scaffolding 1A and 1B can also be easily performed.
