Description

[Technical Field]

[0001] The present invention relates to a suspended scaffolding assembling device and a suspended scaffolding extending method for extending an installed suspended scaffolding. [Background technology]

[0002] There is a known method for assembling a suspended scaffold in which, when expanding the suspended scaffold, components constituting the suspended scaffold are sent outward from the already installed suspended scaffold. For example, Patent Document 1 discloses a method for assembling a suspended scaffold in which a scaffolding frame is formed by a plurality of main single pipes and a plurality of sub-single pipes tied to the main single pipes, in which the sub-single pipes are sent outward from the suspended scaffold.

[0003] In the method of assembling a suspended scaffolding disclosed in Patent Document 1, a temporary single pipe is hung from a structure directly above and parallel to the secondary single pipe that makes up the existing suspended scaffolding so that it can be sent outward from the existing suspended scaffolding, and then the tip of a new secondary single pipe to be connected to each secondary single pipe that makes up the existing suspended scaffolding is connected to the tip of the temporary single pipe via a connecting member, and the temporary single pipe and the new secondary single pipe are sent outward from the existing suspended scaffolding. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5022524 Summary of the Invention [Problem to be solved by the invention]

[0005] In the method of assembling a suspended scaffolding disclosed in Patent Document 1, before sending out a new secondary single pipe from an existing suspended scaffolding, it is necessary to hang the temporary single pipe above the suspended scaffolding and connect the tip of the new secondary single pipe to the tip of the temporary single pipe with a connecting member, and after sending out the new secondary single pipe from the suspended scaffolding, it is necessary to remove the connecting member. Also, in the method of assembling a suspended scaffolding disclosed in Patent Document 1, the new secondary single pipes must be sent out one by one to the outside of the suspended scaffolding using the above-mentioned procedure.

[0006] Therefore, the method of Patent Document 1 does not provide very good workability when extending an existing suspended scaffolding, i.e., an installed suspended scaffolding. Therefore, there is a demand for a suspended scaffolding assembly device that can improve the workability when extending an installed suspended scaffolding.

[0007] An object of the present invention is to provide a suspended scaffolding assembly device that can improve the workability of extending an installed suspended scaffolding. [Means for solving the problem]

[0008] A suspended scaffolding assembly device according to one embodiment of the present invention is a suspended scaffolding assembly device for expanding an installed suspended scaffolding having an installed scaffolding support frame formed by connecting multiple scaffolding support members by further connecting other scaffolding support members to the installed suspended scaffolding. The suspended scaffolding assembly device has an attachment unit that is detachably attached to the installed scaffolding support frame, and a transport unit that is connected to the attachment unit and transports an extension scaffolding support frame formed by connecting multiple other scaffolding support members to the outside of the installed suspended scaffolding. The transport unit has an arm unit that extends outward from the installed suspended scaffolding, and a holding unit that moves along the arm unit while holding the extension scaffolding support frame (first configuration).

[0009] In the above-mentioned suspended scaffolding assembly device, the transport unit has a holding unit that moves along an arm unit extending outward from the installed suspended scaffolding. The holding unit moves along the arm unit while holding an expansion scaffolding support frame to which multiple scaffolding support members are pre-connected. That is, the transport unit can transport an expansion scaffolding support frame made up of multiple scaffolding support members outward from the installed suspended scaffolding. Therefore, by expanding the suspended scaffolding using the suspended scaffolding assembly device, the expansion scaffolding support frame made up of multiple scaffolding support members can be connected to the installed scaffolding support frame. Therefore, by expanding the suspended scaffolding using the suspended scaffolding assembly device, the amount of work required to expand the suspended scaffolding can be reduced, thereby shortening the work time, compared to expanding the suspended scaffolding by connecting scaffolding support members one by one to the installed scaffolding support frame.

[0010] Furthermore, the suspended scaffolding assembly device is attachable to and detachable from the scaffolding support frame by means of an attachment portion. That is, after an extension scaffolding support frame is connected to an installed scaffolding support frame, the suspended scaffolding assembly device can be detached from the attached installed scaffolding support frame and attached to the extension scaffolding support frame. This allows the suspended scaffolding to be extended by sequentially attaching the suspended scaffolding assembly device to the scaffolding support frame located in the direction in which the suspended scaffolding is to be extended. Therefore, the suspended scaffolding can be efficiently extended by the suspended scaffolding assembly device. Therefore, a suspended scaffolding assembly device can be provided that can improve the workability of the suspended scaffolding extension work.

[0011] In the suspended scaffolding assembling device of the first configuration, the transport unit has an angle adjustment unit that changes the angle between the horizontal direction of the suspended scaffolding and the direction in which the arm unit extends (second configuration).

[0012] The extension scaffolding support frame held by the holding unit is transported outside the installed suspended scaffolding, and then a suspension member for suspending the suspended scaffolding is attached. With the above-described configuration, the angle between the horizontal direction of the suspended scaffolding and the extension direction of the arm unit can be changed, so the position of the tip of the arm unit can be moved up or down. Therefore, the portion of the extension scaffolding support frame that is held by the holding unit and that is transported outside the installed suspended scaffolding by the arm unit can be moved upward. Since the portion to which the suspension member is attached can be moved upward in this way, the suspension member can be easily attached to the extension scaffolding support frame. Therefore, the workability of attaching the suspension member to the extension scaffolding support frame can be improved.

[0013] In the suspended scaffolding assembling device of the first configuration, the arm section has a fixing section that fixes the position of the holding section relative to the arm section (third configuration).

[0014] This allows, for example, the position of the holding unit relative to the arm unit to be fixed on the base end side of the arm unit. Therefore, the extension scaffolding support frame can be held by the holding unit while the holding unit is positioned close to the installed scaffolding support frame. In other words, the work of having the holding unit hold the extension scaffolding support frame can be performed close to the installed scaffolding support frame. Therefore, the workability of the work of having the holding unit hold the extension scaffolding support frame can be improved.

[0015] In a suspended scaffolding assembly device of any one of the first to third configurations, the conveying section is rotatably connected to the mounting section around an axis extending in the vertical direction of the suspended scaffolding (fourth configuration).

[0016] This allows the tip of the arm to be positioned inside the installed suspended scaffolding. That is, the mounting part can be attached to the installed scaffolding support frame with the tip of the arm positioned inside the installed suspended scaffolding. This makes it easy to attach the mounting part to the installed scaffolding support frame.

[0017] In the suspended scaffolding assembling device of the second configuration, the transport unit has a columnar first support unit connected to the mounting unit and extending in the vertical direction, with the base end of the arm unit connected to its lower end, and a rod-shaped second support unit connecting the upper end of the first support unit to the tip end of the arm unit. The second support unit is configured to be able to change the length from a first connection position, which is a connection position with the first support unit, to a second connection position, which is a connection position with the arm unit. The angle adjustment unit changes the length of the second support unit from the first connection position to the second connection position, thereby changing the angle between the horizontal direction of the suspended scaffolding and the extension direction of the arm unit (fifth configuration).

[0018] By changing the length of the second support section from the connection position with the first support section to the connection position with the arm section, the position of the tip of the arm section can be moved up and down. This makes it possible to easily move up and down the portion of the extension scaffolding support frame that is held by the holding section and that is transported outside the installed suspended scaffolding by the arm section and connected to the installed scaffolding support frame. This improves the workability of attaching the hanging members that suspend the suspended scaffolding to the extension scaffolding support frame.

[0019] A suspended scaffolding expansion method according to one embodiment of the present invention is a method for expanding an installed suspended scaffolding having an installed scaffolding support frame formed by connecting multiple scaffolding support members by further connecting other scaffolding support members to the installed suspended scaffolding. The suspended scaffolding expansion method includes a scaffolding support frame assembly process for assembling an extension scaffolding support frame to be connected to the installed scaffolding support frame by connecting multiple scaffolding support members to each other, an attachment process for attaching a suspended scaffolding assembly device to the installed scaffolding support frame for transporting the extension scaffolding support frame outward from the installed suspended scaffolding, a transport process for transporting the extension scaffolding support frame outward from the installed suspended scaffolding by the suspended scaffolding assembly device, and a connection process for connecting the extension scaffolding support frame transported outward by the suspended scaffolding assembly device to the installed scaffolding support frame (first method).

[0020] In the above-described suspended scaffolding expansion method, first, a scaffolding support frame in which a plurality of scaffolding support members are connected to each other is pre-assembled. In the suspended scaffolding expansion method, the pre-assembled scaffolding support frame is transported outside the installed suspended scaffolding by a suspended scaffolding assembly device. In this way, in the suspended scaffolding expansion method, the pre-assembled scaffolding support frames can be sequentially connected to the installed scaffolding support frames. Therefore, in the suspended scaffolding expansion method, the amount of work required to expand the suspended scaffolding can be reduced, thereby shortening the work time, compared to when expanding the suspended scaffolding by connecting scaffolding support members one by one to the installed scaffolding support frame. Therefore, a suspended scaffolding expansion method that can improve the workability of the suspended scaffolding expansion work can be provided.

[0021] In the first method, the attaching step attaches at least two of the suspended scaffolding assembly devices to the installed scaffolding support frame. The transporting step transports one of the extension scaffolding support frames outward from the installed suspended scaffolding by the at least two suspended scaffolding assembly devices. The connecting step connects the extension scaffolding support frame transported outward by the at least two suspended scaffolding assembly devices to the installed scaffolding support frame (second method).

[0022] This method allows the extension scaffolding support frame to be easily transported outside the installed suspended scaffolding using at least two suspended scaffolding assembly devices. Moreover, because the extension scaffolding support frame can be stably supported by the at least two suspended scaffolding assembly devices, the extension scaffolding support frame can be easily connected to the installed scaffolding support frame. This further improves the workability of the suspended scaffolding expansion work. [Effects of the Invention]

[0023] A suspended scaffolding assembly device according to one embodiment of the present invention includes a mounting section that is detachably attached to an installed scaffolding support frame, and a transport section that is connected to the mounting section and transports an extension scaffolding support frame outward from the installed suspended scaffolding. The transport section includes an arm section that extends outward from the installed suspended scaffolding, and a holding section that moves along the arm section while holding the extension scaffolding support frame.

[0024] With this configuration, the extension scaffolding support frame can be sent outward from the installed suspended scaffolding and connected to the installed scaffolding support frame. Furthermore, the suspended scaffolding can be extended by sequentially attaching the suspended scaffolding assembly device to the scaffolding support frame located in the direction of extension of the suspended scaffolding. Therefore, a suspended scaffolding assembly device can be provided that can improve the workability of the suspended scaffolding extension work. [Brief explanation of the drawings]

[0026] (Embodiment 1) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same or corresponding parts in the drawings are designated by the same reference numerals, and their description will not be repeated. Furthermore, the dimensions of the components in each drawing do not faithfully represent the actual dimensions of the components, the dimensional ratios of the components, etc.

[0027] In the following description, the direction in which the scaffolding plank 102 extends is referred to as the horizontal direction, and the thickness direction of the scaffolding plank 102 is referred to as the up-down direction. The horizontal direction includes not only a direction horizontal to the ground, but also a direction inclined to the ground to such an extent that the scaffolding 100 functions as a suspended scaffolding 100. The up-down direction is the vertical direction or a direction perpendicular to the horizontal direction.

[0028] In the following description, expressions such as "fix," "connect," and "attach" include not only cases where members are directly fixed to each other, but also cases where members are fixed via other members. In other words, in the following description, expressions such as "fix" include both direct and indirect fixation of members to each other.

[0029] (Configuration of suspended scaffolding) The suspended scaffolding assembly device 1 according to this embodiment is an apparatus used to extend an already installed suspended scaffolding 100. First, with reference to Figs. 1 to 4, a brief description will be given of the suspended scaffolding 100 that is extended by the suspended scaffolding assembly device 1. Fig. 1 is a perspective view showing a schematic configuration of the suspended scaffolding 100. Fig. 1 also shows a portion of the suspended scaffolding 100. The suspended scaffolding 100 is installed below a structure by being suspended from the structure using suspension members 108 such as wires and chains. The suspended scaffolding 100 is used in work environments where it is difficult to install scaffolding on the ground, such as in the construction of structures such as bridges.

[0030] The suspended scaffolding 100 has a scaffolding support frame 101 and a plurality of scaffolding planks 102. The scaffolding support frame 101 is configured in a frame shape by connecting a plurality of horizontally extending scaffolding support members 110 to each other. In detail, the plurality of scaffolding support members 110 include a plurality of columnar first support members 111 that extend horizontally in a predetermined direction, and a plurality of columnar second support members 112 that extend in a direction intersecting the direction in which the first support members 111 extend. The frame-shaped scaffolding support frame 101 is configured by connecting the longitudinal ends of the second support members 112 to the pair of first support members 111, respectively.

[0031] As shown in Fig. 1, the first support member 111 has a plurality of flange-shaped connection portions 113 positioned at predetermined intervals in the longitudinal direction. As shown in Fig. 2, the connection portions 113 have protrusions that protrude horizontally, upward, and downward from the outer circumferential surface of the first support member 111. The second support member 112 is connected to lateral protrusions 113a of the connection portions 113 that protrude horizontally.

[0032] As shown in Figure 1, of the connection part 113, an upper protruding part 113b that protrudes upward can be attached with a hanging member 108 that suspends the suspended scaffolding 100. In addition, a mounting part 2 (see Figure 5) and a holding part 7 (see Figure 9) of the suspended scaffolding assembly device 1, which will be described later, can be attached to the upper protruding part 113b.

[0033] The multiple scaffolding planks 102 are supported by the scaffolding support frame 101 so as to extend horizontally. More specifically, the multiple scaffolding planks 102 are spanned across second support members 112 of the scaffolding support frame 101. The multiple scaffolding planks 102 are fixed to the second support members 112. The multiple scaffolding planks 102 form the floor of a work area for workers working on the suspended scaffolding 100. Hereinafter, a suspended scaffolding to which the multiple scaffolding planks 102 are fixed and which is suspended from a structure by hanging members 108, i.e., an installed suspended scaffolding, will be simply referred to as the suspended scaffolding 100. Furthermore, the scaffolding support frame 101 constituting the suspended scaffolding 100, which is an installed suspended scaffolding, will be referred to as the installed scaffolding support frame 101.

[0034] 3 and 4 are diagrams schematically showing a method for extending the suspended scaffolding 100 having the above-described configuration. In Fig. 4, for the sake of explanation, the scaffolding planks 102 are shown by two-dot chain lines. Also, in Fig. 4, for the sake of explanation, the suspension members 108 that suspend the suspended scaffolding 100 are omitted.

[0035] As shown in Figure 3, the suspended scaffolding 100 is suspended below a structure T by suspension members 108. As shown in Figures 3 and 4, the suspended scaffolding 100 is expanded by connecting an expansion scaffolding support frame 101a to the installed scaffolding support frame 101 while it is suspended.

[0036] As shown in Figure 4, the expansion scaffolding support frame 101a has one first support member 111a and multiple second support members 112a. One of the longitudinal ends of the multiple second support members 112a is connected to the first support member 111a. The other of the longitudinal ends of the multiple second support members 112a is open. The first support member 111a of the expansion scaffolding support frame 101a has multiple flange-shaped connecting portions 113, similar to the first support member 111 of the installed scaffolding support frame 101.

[0037] The suspended scaffolding 100 is expanded using a suspended scaffolding assembling device 1 (see FIG. 5) according to this embodiment. Details of the method for expanding the suspended scaffolding 100 using the suspended scaffolding assembling device 1 will be described later.

[0038] (Hanging scaffolding assembly device) Next, the suspended scaffolding assembling device 1 will be described with reference to FIGS.

[0039] FIG. 5 is a perspective view of the suspended scaffolding assembly device 1. As shown in FIG. 5, the suspended scaffolding assembly device 1 has an attachment unit 2 and a transport unit 3. The attachment unit 2 is detachably attached to an installed scaffolding support frame 101. The transport unit 3 is connected to the attachment unit 2. The transport unit 3 has an arm unit 5 and a holding unit 7. The arm unit 5 extends outward from the scaffolding support frame 101 to which the attachment unit 2 is attached. The holding unit 7 moves along the arm unit 5 in the extension direction of the arm unit 5. The holding unit 7 is capable of holding an extension scaffolding support frame 101a connected to the installed scaffolding support frame 101. While holding the extension scaffolding support frame 101a, the holding unit 7 moves outward from the suspended scaffolding 100 along the arm unit 5. As a result, the extension scaffolding support frame 101a held by the holding unit 7 is transported outward from the suspended scaffolding 100.

[0040] In this embodiment, the mounting portion 2 has a first member 21, a second member 22, a third member 23, and a fourth member 24. The first member 21, the second member 22, the third member 23, and the fourth member 24 are cylindrical pipes. The mounting portion 2 is in the shape of a frame in which the first member 21, the second member 22, the third member 23, and the fourth member 24 are connected to each other at their ends.

[0041] Specifically, the first member 21 and the second member 22 are arranged in parallel. The first member 21 is longer than the second member 22. The third member 23 is connected to one of the longitudinal ends of the first member 21 and one of the longitudinal ends of the second member 22. The third member 23 is arranged to extend in a direction perpendicular to the first member 21 and the second member 22.

[0042] The fourth member 24 is connected to the other of the longitudinal ends of the first member 21 and the other of the longitudinal ends of the second member 22. The fourth member 24 is disposed between the first member 21 and the second member 22 so as to extend in a direction inclined with respect to the axial direction of the first member 21 and the second member 22.

[0043] The mounting unit 2 is detachably attached at its lower ends to the suspended scaffolding 100 so that the first member 21 and the second member 22 extend in the vertical direction. In particular, of the longitudinal ends of the first member 21 and the second member 22, the end to which the third member 23 is connected is coupled to the connection portion 113 of the first support member 111 of the scaffolding support frame 101. In other words, the suspended scaffolding assembly device 1 is detachably attached to the scaffolding support frame 101 via the mounting unit 2. In the following description, the vertical direction of the suspended scaffolding assembly device 1 when attached to the suspended scaffolding 100 is referred to as the vertical direction of the suspended scaffolding assembly device 1.

[0044] The mounting section 2 can also be attached to an expansion scaffolding support frame 101a connected to an installed scaffolding support frame 101. This makes it possible to expand the suspended scaffolding 100 by sequentially attaching the suspended scaffolding assembly device 1 to an installed scaffolding support frame 101 located in the direction in which the suspended scaffolding 100 is to be expanded. Therefore, the suspended scaffolding 100 can be efficiently expanded by the suspended scaffolding assembly device 1.

[0045] In this embodiment, the transport unit 3 has a columnar first support unit 4, a columnar arm unit 5, a rod-shaped second support unit 6, a holding unit 7, and a plurality of handle units 8. The first support unit 4, the arm unit 5, and the second support unit 6 are connected to each other, so that the transport unit 3 has a substantially right-angled triangular shape with the second support unit 6 as the hypotenuse.

[0046] Specifically, the first support portion 4 is disposed so as to extend in the vertical direction. The first support portion 4 is connected to the first member 21 of the mounting portion 2 so as to extend parallel to the first member 21. The first support portion 4 is connected to the first member 21 so as to be rotatable around the outer periphery of the first member 21 in the circumferential direction of the first member 21. That is, the conveying portion 3 rotates around the axis of the first member 21 of the mounting portion 2, as shown in FIG. 6.

[0047] This allows the tip of the arm unit 5 to be positioned inside the suspended scaffolding 100. In other words, the mounting unit 2 can be attached to the installed scaffolding support frame 101 with the tip of the arm unit 5 positioned inside the suspended scaffolding 100. This allows the mounting unit 2 to be easily attached to the installed scaffolding support frame 101.

[0048] A first connection part 41 is fixed to the upper end part of the first support part 4. The first support part 4 is connected to the second support part 6 via the first connection part 41. The detailed configuration of the connection part between the first support part 4 and the second support part 6 will be described later.

[0049] As shown in FIG. 5, the arm 5 is connected to the lower end of the first support 4 and extends in a direction intersecting with the first support 4. The arm 5 is connected to the first support 4 by a pin. That is, the arm 5 is rotatably connected to the first support 4 so that the angle of the arm 5 relative to the first support 4 can be changed. This allows the tip of the arm 5 to move up and down, as shown in FIG. 7.

[0050] 5, a second connection part 51 is fixed to the tip of the arm part 5. The arm part 5 is connected to the second support part 6 via the second connection part 51. The detailed configuration of the connection part between the arm part 5 and the second support part 6 will be described later.

[0051] In this embodiment, the arm unit 5 has a rail 52 and a stopper 53. The rail 52 is provided on the underside of the arm unit 5 and extends along the longitudinal direction of the arm unit 5. A holding unit 7, which will be described later, is movably attached to the rail 52. The rail 52 has the same configuration as a general rail. Therefore, a detailed description of the rail 52 will be omitted.

[0052] The stopper 53 restricts the movement of the holder 7 along the arm 5. In this embodiment, the stopper 53 is provided on the first support 4 side of the arm 5, and fixes the position of the holder 7 on the first support 4 side. The stopper 53 is a fixing portion of the present invention.

[0053] As shown in FIG. 5, the second support part 6 connects the upper end of the first support part 4 and the tip of the arm part 5. One of both longitudinal ends of the second support part 6 is connected to the first support part 4 via a first connection part 41. The other longitudinal end of the second support part 6 is connected to the arm part 5 via a second connection part 51. The detailed configurations of the connection part between the second support part 6 and the first support part 4 and the connection part between the second support part 6 and the arm part 5 will be described later.

[0054] The second support part 6 is rotatable around the axis of the second support part 6 while connected to the first support part 4 and the arm part 5. In this embodiment, the second support part 6 is provided with a first rotation operation part 62, a second rotation operation part 63, and a third rotation operation part 64, which are operation parts that rotate the second support part 6 around the axis.

[0055] The first rotation operation unit 62 is provided at the tip of one end of the second support unit 6. The second rotation operation unit 63 is provided at the tip of the other end of the second support unit 6. In this embodiment, the first rotation operation unit 62 and the second rotation operation unit 63 have a polygonal shape when viewed in the axial direction of the second support unit 6. Therefore, by rotating the first rotation operation unit 62 and the second rotation operation unit 63 using a tool or the like, the second support unit 6 can be rotated around the axis of the second support unit. Note that the first rotation operation unit 62 and the second rotation operation unit 63 may have other shapes as long as they can be rotated using a tool or the like.

[0056] The third rotation operation unit 64 is provided on the outer peripheral surface of the second support unit 6. The third rotation operation unit 64 is an operation unit that an operator holds and operates to rotate the second support unit 6 around the axis of the second support unit 6. In other words, the operator can rotate the second support unit 6 around the axis of the second support unit 6 by holding and operating the third rotation operation unit 64 without using tools or the like.

[0057] In this embodiment, the third rotation operation unit 64 is composed of two rod-shaped members extending from the outer circumferential surface of the second support unit 6 in a direction perpendicular to the axial direction of the second support unit 6. The third rotation operation unit 64 is fixed to the second support unit 6 so as not to be rotatable. Therefore, by rotating the two rod-shaped members in the circumferential direction of the second support unit 6, the second support unit 6 can be rotated around the axis of the second support unit 6. The third rotation operation unit 64 is provided on the outer circumferential surface of the second support unit 6 at a position close to the first rotation operation unit 62. Note that the third rotation operation unit may have any shape as long as it can be gripped by an operator and rotate the second support unit 6 around the axis of the second support unit 6. The third rotation operation unit may be provided at a position as long as it can be gripped by an operator and rotate the second support unit 6 around the axis of the second support unit 6.

[0058] The holding unit 7 has a chain 71 and a hanging bracket 72. The upper side of the chain 71 is connected to the rail 52 of the arm unit 5. The hanging bracket 72 is connected to the lower side of the chain 71. The connection portion 113 of the first support member 111a can be attached to the hanging bracket 72. In other words, the holding unit 7 can hold the first support member 111. As shown in FIG. 8 , the holding unit 7 moves along the rail 52 of the arm unit 5.

[0059] The multiple handle portions 8 include two handle portions: a first handle portion 81 and a second handle portion 82. The first handle portion 81 is provided at the upper end of a rectangular column member extending upward from the longitudinal center portion of the arm portion 5. The second handle portion 82 is provided on the outer peripheral surface of the first support portion 4. The multiple handle portions 8 can be grasped by the operator of the suspended scaffolding assembly device 1. This improves the operability of tasks such as holding the first support member 111 on the holding portion 7, rotating the conveying portion 3 relative to the mounting portion 2, and rotating the second support portion 6 around its own axis. The multiple handle portions 8 may be provided at other positions on the conveying portion 3.

[0060] In this embodiment, the transport unit 3 has an angle adjustment unit 9 that changes the angle of the arm unit 5 relative to the first support unit 4. That is, the angle adjustment unit 9 changes the angle between the horizontal direction and the direction in which the arm unit 5 extends. The tip of the arm unit 5 moves in the vertical direction by the angle adjustment unit 9. The detailed configuration of the angle adjustment unit 9 will be described later.

[0061] (Connection structure of arm portion, first support portion, and second support portion) Next, the connection structure between the second support portion 6 and the first support portion 4, and the connection structure between the second support portion 6 and the arm portion 5 will be described.

[0062] 5, the first connection portion 41 of the first support portion 4 has a rotating portion 41a provided with a through hole through which the second support portion 6 passes. The rotating portion 41a is pin-joined to the first connection portion 41 so that the penetrating direction of the through hole relative to the first connection portion 41 changes.

[0063] The second connection portion 51 of the arm portion 5 has a rotating portion 51a provided with a through hole through which the second support portion 6 passes. The rotating portion 51a is pin-joined to the second connection portion 51 so that the penetrating direction of the through hole changes relative to the second connection portion 51. The through hole of the rotating portion 51a has a female thread provided on the inner peripheral surface.

[0064] As shown in FIGS. 5 and 7, the second support portion 6 has a male screw 61 extending in the longitudinal direction on the outer peripheral surface of the lower end portion connected to the arm portion 5.

[0065] An upper end of the second support part 6 passes through the through-hole of the rotating part 41a of the first connecting part 41. At a first connecting position P1 located at the upper end, the second support part 6 is connected to the first connecting part 41 so that its axial movement is restricted and it is rotatable around the axis of the second support part 6.

[0066] The male thread 61 at the lower end of the second support part 6 is threadedly engaged with the female thread in the through hole of the rotating part 51a of the second connection part 51. In other words, the lower end of the second support part 6 is connected to the second connection part 51 so as to be rotatable around the axis of the second support part 6.

[0067] Therefore, the second support part 6 can rotate around the axis of the second support part 6 while connected to the first connection part 41 of the first support part 4 and the second connection part 51 of the arm part 5. When the second support part 6 rotates around the axis, the second connection part 51 moves in the longitudinal direction of the second support part 6. Therefore, the second connection position P2, which is the connection position of the second support part 6 with the second connection part 51, moves in the axial direction of the second support part 6. As a result, the length of the second support part 6 from the first connection position P1 to the second connection position P2 changes.

[0068] As described above, the second support part 6 is provided with the first rotation operation part 62, the second rotation operation part 63, and the third rotation operation part 64, which rotate the second support part 6 around the axis of the second support part 6. That is, by operating the first rotation operation part 62, the second rotation operation part 63, and the third rotation operation part 64, the length from the first connection position P1 to the second connection position P2 in the second support part 6 is changed.

[0069] (Angle adjustment part) In this embodiment, the angle adjustment unit 9 is composed of a male screw 61 of the second support unit 6 and a female screw provided on the inner periphery of the through hole in the rotating part 51a of the second connection part 51 of the arm unit 5. In other words, the male screw 61 of the second support unit 6 and the female screw of the arm unit 5 can change the angle between the horizontal direction of the suspended scaffolding 100 and the direction in which the arm unit 5 extends.

[0070] As described above, by rotating the second support part 6 around the axis, the second connection position P2, which is the connection position of the second support part 6 with respect to the second connection part 51, moves in the axial direction of the second support part 6. As a result, the length of the second support part 6 from the first connection position P1 to the second connection position P2 changes.

[0071] By shortening the length from the first connection position P1 at the second support section 6 with the first support section 4 to the second connection position P2 at the second support section 6 with the arm section 5, the angle of the arm section 5 relative to the first support section 4 becomes smaller. By lengthening the length from the first connection position P1 to the second connection position P2, the angle of the arm section 5 relative to the first support section 4 becomes larger. In other words, the angle adjustment section 9 changes the angle between the horizontal direction of the suspended scaffolding 100 and the direction in which the arm section 5 extends.

[0072] The tip of the arm section 5 moves up and down by changing the angle between the horizontal direction of the suspended scaffolding 100 and the direction in which the arm section 5 extends using the angle adjustment section 9. By moving the tip of the arm section 5 up and down, the holding section 7 connected to the arm section 5 can be moved up and down.

[0073] A connection portion 113 of the first support member 111a of the expansion scaffolding support frame 101a is attached to the holding portion 7. Therefore, by moving the holding portion 7 in the vertical direction, the portion held by the holding portion 7, i.e., the first support member 111a, can be moved in the vertical direction.

[0074] The hanging members 108 that suspend the suspended scaffolding 100 are attached to the other connection parts 113 of the first support member 111a. The angle adjustment unit 9 can move upward the first support member 111a, which has the connection parts 113 to which the hanging members 108 are attached. By moving upward the first support member 111a, which has the connection parts 113 to which the hanging members 108 are attached, the hanging members 108 can be easily attached to the connection parts 113. Therefore, the angle adjustment unit 9 can improve the workability of attaching the hanging members 108 to the extension scaffolding support frame 101a.

[0075] Furthermore, when the tip of the arm portion 5 is moved in the vertical direction, the angle formed by the arm portion 5 and the first support portion 4, the angle formed by the arm portion 5 and the second support portion 6, and the angle formed by the first support portion 4 and the second support portion 6 each change.

[0076] In this embodiment, as described above, the arm portion 5 and the first support portion 4 are joined by a pin. The first support portion 4 has a rotating portion 41a joined by a pin to the first support portion 4 at a connection portion with the second support portion 6. The arm portion 5 has a rotating portion 51a joined by a pin to the arm portion 5 at a connection portion with the second support portion 6. In other words, the first support portion 4, the arm portion 5, and the second support portion 6 are connected to one another so as to be freely rotatable. This prevents loads due to angle changes from being applied to the connection portion between the arm portion 5 and the first support portion 4, the connection portion between the first support portion 4 and the second support portion 6, and the connection portion between the arm portion 5 and the second support portion 6.

[0077] As shown in FIG. 9 , the suspended scaffolding assembly device 1 having the above configuration is attached to an installed scaffolding support frame 101 via the mounting unit 2. With the scaffolding assembly device 1 attached to the installed scaffolding support frame 101, the arm unit 5 extends outward from the suspended scaffolding 100. The holding unit 7 is capable of holding the extension scaffolding support frame 101a. As shown in FIG. 10 , with the holding unit 7 holding the extension scaffolding support frame 101a, the holding unit 7 is capable of moving outward from the suspended scaffolding 100 along the arm unit 5. This allows the suspended scaffolding assembly device 1 to transport the extension scaffolding support frame 101a outward from the suspended scaffolding 100.

[0078] That is, in the scaffolding assembly device 1, the transport unit 3 can transport the expansion scaffolding support frame 101a, to which multiple scaffolding support members 110 have been previously connected, outward from the installed scaffolding support frame 101. Therefore, by expanding the suspended scaffolding using the suspended scaffolding assembly device 1, the expansion scaffolding support frame 101a, which is made up of multiple scaffolding support members 110, can be connected to the installed scaffolding support frame 101. Therefore, by expanding the suspended scaffolding using the suspended scaffolding assembly device 1, it is possible to reduce the amount of work required to expand the suspended scaffolding 100 and shorten the work time, compared to when the suspended scaffolding 100 is expanded by connecting the scaffolding support members 110 one by one to the installed scaffolding support frame 101. Therefore, it is possible to provide a suspended scaffolding assembly device 1 that can improve the workability of the work of expanding the suspended scaffolding.

[0079] (How to extend a suspended scaffold) Next, a method for expanding a suspended scaffolding 100 using a suspended scaffolding assembling device 1 will be described with reference to Fig. 4, Fig. 9 to Fig. 11, and Fig. 12A to Fig. 12F. Fig. 11 is a flow diagram of the suspended scaffolding expansion method. Fig. 12A to Fig. 12F are schematic diagrams for explaining a method for expanding a suspended scaffolding 100. Note that, for the sake of explanation, Fig. 12A to Fig. 12F simplify the mounting section 2 of the suspended scaffolding assembling device 1. Also, Fig. 12A to Fig. 12E omit some of the illustration of the hanging members 108 that suspend the suspended scaffolding 100.

[0080] As shown in FIG. 11, the suspended scaffolding expansion method includes a scaffolding support frame assembling process S1, an attachment process S2, a transporting process S3, a connecting process S4, and a suspension member attachment process S5.

[0081] In the scaffolding support frame assembling process S1, a plurality of scaffolding support members 110 are connected to one another to assemble an expansion scaffolding support frame 101a to be connected to the installed scaffolding support frame 101. In detail, as shown in Fig. 4, one of the longitudinal ends of a plurality of second support members 112a is connected to one first support member 111a to obtain the expansion scaffolding support frame 101a. The other longitudinal ends of the plurality of second support members 112a are open.

[0082] In the attachment step S2, the attachment sections 2 of multiple suspended scaffolding assembly devices 1 are attached to first support members 111 of the installed scaffolding support frame 101 that are located in the direction in which the suspended scaffolding 100 is desired to be extended. In this embodiment, as shown in Fig. 9, the attachment sections 2 of two suspended scaffolding assembly devices 1 are each attached to spaced apart positions on one first support member 111 that is located in the direction in which the suspended scaffolding 100 is desired to be extended. Note that the attachment step S2 may be performed before the scaffolding support frame assembling step S1.

[0083] In the transport step S3, as shown in FIG. 12A, one expansion scaffolding support frame 101a is transported outward from the suspended scaffolding 100 by two suspended scaffolding assembly devices 1. Specifically, as shown in FIG. 9, the holding units 7 of the two suspended scaffolding assembly devices 1 are attached to the two connection units 113 of the first support members 111a of the expansion scaffolding support frame 101a. As a result, the expansion scaffolding support frame 101a is held at two points by the two suspended scaffolding assembly devices 1. Next, as shown in FIG. 12B, the expansion scaffolding support frame 101a is pushed outward from the installed scaffolding support frame 101. The holding units 7 move along the rails 52 while holding the expansion scaffolding support frame 101a. As a result, the expansion scaffolding support frame 101a is transported outward from the suspended scaffolding 100, as shown in FIG. 10.

[0084] In the connecting step S4, as shown in Fig. 12C, the expansion scaffolding support frame 101a that has been transported outward is connected to the installed scaffolding support frame 101. Specifically, the open end of the second support member 112a of the expansion scaffolding support frame 101a is connected to the first support member 111 of the installed scaffolding support frame 101. Thereafter, as shown in Fig. 12D, the scaffolding plank 102a is fixed to the expansion scaffolding support frame 101a that has been connected to the installed scaffolding support frame 101.

[0085] Next, in the hanging member attachment process S5, hanging members 108 are attached to the expansion scaffolding support frame 101a connected to the installed scaffolding support frame 101. More specifically, as shown in FIG. 12E, the second support part 6 is rotated about its axis to move the holding part 7 upward. As a result, the part of the expansion scaffolding support frame 101a connected to the installed scaffolding support frame 101 that is held by the holding part 7 moves upward. Next, the hanging members 108 are attached to the connection parts 113 (see FIG. 9) of the expansion scaffolding support frame 101a that has moved upward. After the hanging members 108 are attached to the connection parts 113 of the expansion scaffolding support frame 101a, the holding parts 7 are moved downward. As a result, the expansion scaffolding support frame 101a changes from being supported by the holding parts 7 to being supported by the hanging members 108.

[0086] The above steps expand the suspended scaffolding 100. After that, as shown in Figure 12F, the mounting portion 2 of the suspended scaffolding assembling device 1 is removed from the installed scaffolding support frame 101.

[0087] The mounting section 2 of the suspended scaffolding assembly device 1 is detachable from the installed scaffolding support frame 101. Therefore, the removed mounting section 2 of the suspended scaffolding assembly device 1 can be attached to a scaffolding support frame 101 located in the direction in which the suspended scaffolding 100 is desired to be further expanded. In this way, the suspended scaffolding 100 can be expanded by sequentially connecting the extension scaffolding support frames 101a to the scaffolding support frames 101 while sequentially replacing the suspended scaffolding assembly device 1 with the scaffolding support frames 101 located in the direction in which the suspended scaffolding 100 is to be expanded.

[0088] In the above-described suspended scaffolding expansion method, an expansion scaffolding support frame 101a is pre-assembled, in which a plurality of scaffolding support members 110 are connected to one another. In the suspended scaffolding expansion method, the pre-assembled expansion scaffolding support frame 101a is transported to the outside of the installed suspended scaffolding 100 by a suspended scaffolding assembly device 1.

[0089] As a result, in the suspended scaffolding expansion method, pre-assembled expansion scaffolding support frames 101a can be sequentially connected to the installed scaffolding support frame 101. Therefore, in the suspended scaffolding expansion method, it is possible to reduce the work required to expand the suspended scaffolding 100 and shorten the work time, compared to when the suspended scaffolding 100 is expanded by connecting the scaffolding support members 110 one by one to the installed scaffolding support frame 101. Therefore, it is possible to provide a suspended scaffolding expansion method that can improve the workability of the expansion work of the suspended scaffolding 100.

[0090] Furthermore, in this embodiment, the extension scaffolding support frame 101a is transported to the outside of the installed suspended scaffolding 100 by two suspended scaffolding assembly devices 1. This allows the extension scaffolding support frame 101a to be easily transported to the outside of the installed suspended scaffolding 100, and also allows it to be easily connected to the installed scaffolding support frame 101. Therefore, the workability of the extension work of the suspended scaffolding 100 can be further improved.

[0091] (Other embodiments) Although the embodiments of the present invention have been described above, the above-described embodiments are merely examples for carrying out the present invention. Therefore, the present invention is not limited to the above-described embodiments, and it is possible to appropriately modify the above-described embodiments within the scope of the spirit of the present invention.

[0092] In the first embodiment, the mounting portion 2 is in the form of a frame in which a first member 21, a second member 22, a third member 23, and a fourth member 24 are connected to one another. However, the mounting portion may have a configuration that allows it to be attached to the scaffolding support frame. For example, the mounting portion may be formed of a single member. The mounting portion does not have to be in the form of a frame.

[0093] In the first embodiment, the first member 21 of the mounting part 2 extends in the vertical direction. However, the first member 21 does not have to extend in the vertical direction. The mounting part only needs to have a configuration that can support the transport part so that it can rotate around an axis that extends in the vertical direction of the suspended scaffolding.

[0094] In the first embodiment, the transport section 3 has a shape of a substantially right-angled triangle, but the transport section may have other shapes.

[0095] In the first embodiment, the transport unit 3 is connected to the mounting unit 2 and has a first support unit 4 to which the arm unit 5 is connected. However, the transport unit does not necessarily have to have a first support unit. In this case, the arm unit may be directly connected to the mounting unit.

[0096] In the first embodiment, the transport unit 3 has the angle adjustment unit 9. However, the transport unit does not necessarily have to have the angle adjustment unit.

[0097] In the first embodiment, the angle adjustment unit 9 is configured by the male screw 61 of the second support unit 6 and a female screw provided on the inner periphery of the through hole in the rotating portion 51a of the second connection portion 51 of the arm unit 5. That is, the male screw 61 of the second support unit 6 rotates relative to the female screw of the arm unit 5, thereby moving the connection position of the second support unit 6 with the arm unit 5, and as a result, moving the tip of the arm unit 5 in the vertical direction. However, the angle adjustment unit may be realized by other means for moving the position of the tip of the arm unit in the vertical direction.

[0098] In the first embodiment, the transport unit 3 is configured so that the angle formed between the arm unit 5 and the first support unit 4 is variable. However, the transport unit may be configured so that the angle formed between the arm unit and the first support unit does not change.

[0099] That is, the arm section may be fixed to the first support section, or, for example, as in the transport section 203 of the suspended scaffolding assembling device 201 shown in FIG. 13 , the arm section 205 may be fixed to the first support section 204 via the third support section 206. The transport section 203 of the suspended scaffolding assembling device 201 has a first support section 204, an arm section 205, a third support section 206, a holding section 7, and a plurality of handle sections 208. The third support section 206 is fixed to the upper surface of the arm section 205, and has its base end fixed to the first support section 204.

[0100] In this way, a suspended scaffolding assembling device 201 that does not have an angle adjustment function for changing the angle between the arm unit 205 and the first support unit 204 may be provided with a hook 261 at the tip of the third support unit 206, as shown in FIG. 13 . By attaching a chain or the like to the hook 261 and suspending the transport unit 203 from above, and then winding up the chain using another device, the tip of the arm unit 205 can be moved upward. This allows the extension scaffolding support frame held by the holding unit 7 to be moved upward, similar to the suspended scaffolding assembling device 1 of embodiment 1. This allows hanging members for suspending the suspended scaffolding to be easily attached to the extension scaffolding support frame.

[0101] Unlike the transport unit 3 of the suspended scaffolding assembling device 1 of embodiment 1, the transport unit 203 of the suspended scaffolding assembling device 201 does not have a second support unit that connects the upper end of the first support unit 204 and the tip end of the arm unit 205. Therefore, the vertical length of the suspended scaffolding assembling device 201 is shorter than that of the suspended scaffolding assembling device 1 of embodiment 1. Therefore, the suspended scaffolding assembling device 201 can be used, for example, in a work environment where the distance between the installed scaffolding support frame to which the suspended scaffolding assembling device 201 is attached and the underside of the structure from which the suspended scaffolding is suspended is short.

[0102] In the first embodiment, the arm 5 has a rail 52 along which the holder 7 moves. However, the arm need only have a configuration that allows the holder to move, and does not necessarily have to have a rail. For example, the arm may have a groove along which the holder can move.

[0103] In the first embodiment, the arm unit 5 has a stopper 53 that fixes the position of the holding unit 7 that moves on the rail 52. However, the arm unit does not have to have a stopper. By having the arm unit 5 have the stopper 53, for example, when the extension scaffolding support frame 101a is held by the holding unit 7, the holding unit 7 can be fixed at a position close to the installed scaffolding support frame 101. Therefore, the workability of the operation of holding the extension scaffolding support frame 101a by the holding unit 7 can be improved.

[0104] In the first embodiment, the arm 5 has a stopper 53 that fixes the position of the holding portion 7 on the first support portion 4 side. However, the arm may have a stopper that fixes the position of the holding portion at another position. The arm may have multiple stoppers that can fix the position of the holding portion at multiple positions.

[0105] In the first embodiment, the second support unit 6 has three rotation operation units: a first rotation operation unit 62, a second rotation operation unit 63, and a third rotation operation unit 64. However, the second support unit may have one or two rotation operation units. The second support unit may not have any rotation operation units.

[0106] In the first embodiment, the rail 52 along which the holding unit 7 moves is provided below the arm unit 5. However, the rail may be provided at a position other than below the arm unit.

[0107] In the first embodiment, the suspended scaffolding 100 is expanded using two suspended scaffolding assembly devices 1. However, the suspended scaffolding may be expanded using one suspended scaffolding assembly device. The suspended scaffolding may be expanded using three or more suspended scaffolding assembly devices.

[0108] In the first embodiment, the holding unit 7 that holds the extension scaffolding support frame 101a moves along the arm unit 5. The extension scaffolding support frame 101a is transported to the outside of the installed suspended scaffolding 100 by the movement of the holding unit 7. However, the holding unit may be fixed to the tip of the arm unit, and the length of the arm unit may be changed. In this case, the extension scaffolding support frame is transported to the outside of the installed suspended scaffolding by changing the length of the arm unit.

[0109] In the first embodiment, the suspended scaffolding assembling device 1 has two handle units 8. However, the suspended scaffolding assembling device does not have to have any handle units. The suspended scaffolding assembling device may have one or three or more handle units.

[0110] In the first embodiment, the suspended scaffolding assembly device 1 transports an extension scaffolding support frame 101a made up of one first support member 111a and multiple second support members 112a to the outside of the suspended scaffolding 100. However, the suspended scaffolding assembly device may transport an extension scaffolding support frame made up of multiple first support members and multiple second support members to the outside of the suspended scaffolding. The suspended scaffolding assembly device may transport an extension scaffolding support frame made up of multiple first support members and one second support member to the outside of the suspended scaffolding.

[0111] In the first embodiment, a method has been described in which the suspended scaffolding 100 is expanded horizontally and in a direction perpendicular to the longitudinal direction of the first support member 111 by the suspended scaffolding assembly device 1. However, the suspended scaffolding assembly device may also be used when expanding the suspended scaffolding horizontally and in the longitudinal direction of the first support member.

[0112] In the above embodiment, the suspended scaffolding assembling device 1 is used when expanding an already installed suspended scaffolding 100. However, the suspended scaffolding assembling device may also be used when assembling a suspended scaffolding. [Industrial Applicability]

[0113] The present invention can be used in a device for extending an already installed suspended scaffolding. [Explanation of symbols]
