Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional case as shown in Patent Document 1, since the stage scaffolds are arranged over the entire construction area as much as possible, a large number of stage scaffolds corresponding to the area of the entire construction area are used. Therefore, there are problems such as not only the cost of the members of the scaffold itself but also a great deal of labor and time required for loading and unloading the stage scaffolds and for transferring between floors by a construction elevator. In addition, as a method of not providing a stage scaffold, there is also a supplementary method of performing work while moving an aerial work platform, but since the working area is narrow and the workability is also reduced, there is room for improvement in this regard.

[0005] The present invention has been made in view of the above-described problems, and an object thereof is to provide a stage scaffold traveling system that can reduce the cost of the members of the stage scaffold, improve the work efficiency of replacing the stage scaffold, and shorten the work process.

Means for Solving the Problems

[0006] (1) Embodiment 1 of the stage scaffolding travel system according to the present invention comprises a work scaffolding unit equipped with wheels that roll on a floor surface, a transport trolley that travels a stage scaffolding formed by integrally connecting a plurality of the work scaffolding units, and a connecting jig that is detachably attached to the transport trolley and fixed to the stage scaffolding, wherein the stage scaffolding is provided to be able to travel as the transport trolley moves.

[0007] According to the stage scaffolding travel system of the present invention, a stage scaffolding can be provided by combining multiple work scaffolding units so that scaffolding is secured only for the minimum necessary work area within the construction area, rather than covering the entire area. Therefore, on the floor, it is not necessary to provide stage scaffolding over the entire construction area as in the conventional method, and a stage scaffolding of a predetermined size, fixed to a transport trolley by a connecting jig, can be moved together with the transport trolley and moved to other work locations on the floor. In this way, the present invention can reduce the number of components that make up the stage scaffolding, and thus reduce the cost of components. Furthermore, by reducing the number of stage scaffolding components in this invention, the effort required to reposition the stage scaffolding is reduced, thereby improving repositioning efficiency, securing working time, and shortening the work process.

[0008] (2) A second aspect of the present invention is a stage scaffolding travel system according to aspect 1, wherein it is preferable that there is a passage space below the stage scaffolding through which the transport trolley can pass.

[0009] In this case, the transport cart can be positioned at a predetermined fixed location below the stage scaffolding by passing through a passage space formed beneath the stage scaffolding. That is, by providing a passage space beneath the stage scaffolding, the transport cart can be moved in and out of the fixed position of the stage scaffolding. Therefore, for example, when setting up multiple stage scaffoldings, multiple stage scaffoldings can be moved sequentially and rearranged using a single transport cart, thus reducing the number of transport carts required and lowering costs.

[0010] (3) A third aspect of the present invention is a stage scaffolding travel system according to aspect 1 or aspect 2, wherein the transport trolley is preferably positioned in the center of the stage scaffolding, which is integrated by a plurality of work scaffolding units, in a plan view.

[0011] In this case, the transport trolley can be fixed in a position where the load balance is evenly distributed at the center of the stage scaffolding, which has a predetermined area, when viewed from above. Therefore, the stage scaffolding can be smoothly transported in all directions by the transport trolley.

[0012] (4) A fourth aspect of the present invention is a stage scaffolding travel system in any one of aspects 1 to 3, wherein the connecting jig comprises a plurality of support columns extending in the vertical direction, a connecting portion connecting the support columns together, and a fixing portion detachably provided on the work scaffolding unit, and the transport trolley preferably has a support portion that detachably supports the lower ends of the support columns.

[0013] In this case, the lower end of the support column is detachably supported on the support part of the transport trolley, thereby supporting the connecting jig on the transport trolley, and the connecting part of the connecting jig is detachably fixed to the work scaffolding unit via a fixing part, thereby integrally fixing the stage scaffolding and the transport trolley. By using the connecting jig in this way, the transport trolley and the stage scaffolding can be easily attached and detached, so for example, the transport trolley can be attached to the stage scaffolding only when changing the stage scaffolding.

[0014] (5) Aspect 5 of the present invention is a stage scaffolding travel system in any one of aspects 1 to 4, wherein the work scaffolding unit has a first scaffolding board that forms a work surface, and the stage scaffolding comprises a plurality of the work scaffolding units arranged at predetermined intervals, and a second scaffolding board arranged between the first scaffolding boards of adjacent work scaffolding units.

[0015] In this case, by providing a second scaffolding board between the first scaffolding boards of adjacent work scaffolding units, a work surface of the stage scaffolding can be formed in which the first and second scaffolding boards are arranged flush with each other. As a result, the number of work scaffolding units can be reduced, making the structure simpler, lighter, and lowering the cost of materials. [Effects of the Invention]

[0016] According to the stage scaffolding travel system of the present invention, it is possible to reduce the cost of stage scaffolding components, improve the work efficiency involved in replacing stage scaffolding, and shorten the work process. [Brief explanation of the drawing]

BEST MODE FOR CARRYING OUT THE INVENTION

[0018] Hereinafter, a stage scaffold traveling system according to an embodiment of the present invention will be described based on the drawings.

[0019] As shown in FIGS. 1 and 2, the stage scaffold traveling system 1 of the present embodiment is used as a work scaffold for construction interior finishing work and the like at a large-scale construction site. The stage scaffold traveling system is provided so as to be replaceable by traveling and moving on the same floor.

[0020] The stage scaffold traveling system 1 includes a work scaffold unit 10, a second scaffold board 20, a transport cart 30, and a connecting jig 40. The stage scaffold traveling system 1 is provided such that the stage scaffold 100 can travel on the floor surface F as the transport cart 30 moves.

[0021] The work scaffold unit 10 includes four leg members 11, a first scaffold board 12 that is supported from below by the four leg members 11 and forms a first work surface 12a, scaffold wheels 13 provided at the lower ends of the respective leg members 11 for rolling on the floor surface F, and a frame member 14 that supports the leg members 11 and the first scaffold board 12 so as to be foldable.

[0022] The upper surface of the work scaffold unit 10 serves as the first work surface 12a of the first scaffold board 12. The first scaffold board 12 is configured by arranging and connecting eight scaffold boards in parallel. As shown in FIG. 1, the work scaffold unit 10 has a rectangular shape in plan view as seen from above. The first scaffold board 12 also has a rectangular shape in plan view. Here, in the work scaffold unit 10, the longitudinal direction will be denoted by reference symbol X1 and the short transverse direction will be denoted by reference symbol X2 and described below.

[0023] The four leg members 11 are respectively arranged at the four corner portions of the rectangular first scaffold board 12.

[0024] The work scaffolding unit 10 has a first scaffolding board 12 that is divided in the middle along the longitudinal direction X1, and can be folded by rotating it around the dividing point as an axis of rotation. In other words, the frame member 14 constitutes a link mechanism that allows the work scaffolding unit 10 to be folded.

[0025] The four leg members 11 are extendable and retractable at the center in the vertical direction. By extending and retracting the four leg members 11, the height of the first scaffolding board 12 can be changed. As shown in Figure 2, pairs of leg members 11 facing each other in the short direction X2 are connected by a horizontal member 15 at the middle and lower parts in the vertical direction. As shown in Figure 3, a passage space S is formed between pairs of leg members 11 facing each other in the longitudinal direction X1, through which at least a transport trolley 30 can pass. The frame member 14 is positioned above the pair of leg members 11 facing each other in the longitudinal direction X1. Therefore, the passage space S is located below the frame member 14. The height of the passage space S from the floor surface F is higher than the height of the transport trolley 30. The length of the passage space S in the short direction X2 is set to be greater than the width dimension of the transport trolley 30. Alternatively, the width dimension of the transport trolley 30 is set to be smaller than the length of the passage space S in the short direction X2.

[0026] The scaffolding wheels 13 roll on the floor surface F. The floor surface F is the surface on which the scaffolding wheels 13 and the drive wheels 32 of the transport trolley 30 (described later) roll together when the stage scaffolding travel system 1 is moving. The scaffolding wheels 13 can be locked to prevent them from rolling.

[0027] As shown in Figures 1 and 2, the work scaffolding units 10 are directly connected in the longitudinal direction X1 and arranged with gaps in the short direction X2. Multiple second scaffolding boards 20 (eight in this case) are arranged in the gaps between the first scaffolding boards 12 of adjacent work scaffolding units 10, 10 so as to be flush with the first scaffolding boards 12.

[0028] The stage scaffolding 100 is formed by integrating a plurality of work scaffolding units 10 arranged at predetermined intervals in the short direction X2, and a plurality of second scaffolding boards 20 provided between the plurality of work scaffolding units 10, thereby forming a stage with a predetermined work area. The planar shape of the stage scaffolding 100 in this embodiment is rectangular, as shown in Figure 1.

[0029] The transport trolley 30 travels along the stage scaffolding 100, which is formed by integrally connecting multiple work scaffolding units 10. The transport trolley 30 is positioned in the center of the stage scaffolding 100 in a plan view. As shown in Figures 4 to 6, the transport trolley 30 is electrically powered and has a trolley body 31 housing a battery-powered drive unit (not shown), and four drive wheels 32, two at the front and two at the rear. The drive wheels 32 roll on the floor surface F. The transport trolley 30 can be operated wirelessly, for example, using a remote controller.

[0030] The transport trolley 30 has a support cylinder 33 (support part) that detachably supports the lower end portion 41a of the support column 41 of the connecting jig 40, which will be described later. The support cylinder 33 is a cylindrical shape with a bottom. The support column 41 of the connecting jig 40 is fitted into the support cylinder 33 from above. In this way, the connecting jig 40 is supported by the transport trolley 30 via the support cylinder 33.

[0031] The connecting fixture 40 is detachably attached to the transport trolley 30 and fixed to the stage scaffolding 100. The connecting fixture 40 consists of a pair of connecting fixtures 40A and 40B of the same shape. Each connecting fixture 40A and 40B includes a plurality (2) of support columns 41 extending in the vertical direction, a connecting portion 42 that connects the support columns 41 together, and a fixing member 43 (fixing portion) that is detachably provided on the work scaffolding unit 10. The connecting portion 42 consists of two horizontally extending members arranged with a vertical gap between them. The lower end 41a of the support column 41 is fitted into a support cylinder 33 provided on the transport trolley 30. When the support column 41 is fitted into the support cylinder 33, the pair of connecting fixtures 40A and 40B are supported by the transport trolley 30 at a predetermined height.

[0032] As shown in Figure 6, the fixing members 43 of the connecting jigs 40A and 40B are provided at both ends 42a of the connecting portion 42. The fixing members 43 are fixing means for detachably fixing the connecting portion 42 to the leg members 11 of the work scaffolding unit 10. For example, single-pipe joints can be used as the fixing members 43.

[0033] A method for moving and rearranging the stage scaffolding travel system 1, configured in this way, on the same floor M will be explained using Figures 1 to 7. In Figure 7, the symbol M indicates the floor on which the stage scaffolding travel system 1 is used for work.

[0034] First, the remote controller is operated to move the transport trolley 30 to the underside of the integrated stage scaffolding 100, which is formed by combining multiple work scaffolding units 10 and second scaffolding boards 20 to create a predetermined scaffolding area. That is, the transport trolley 30 is driven through the passage space S formed in the work scaffolding unit 10 to move the transport trolley 30 to a predetermined fixed position P (see Figure 1) on the stage scaffolding 100.

[0035] Next, as shown in Figures 5 and 6, the stage scaffolding 100 and the transport trolley 30 are connected at the fixed position P using connecting jigs 40A and 40B. Specifically, the support columns 41 of the connecting jigs 40A and 40B are fitted into the support cylinders 33 of the transport trolley 30, and the end portion 42a of the connecting portion 42 is fixed to the leg member 11 using the fixing member 43. In this way, the stage scaffolding 100 and the transport trolley 30 are provided as a single unit.

[0036] Subsequently, by operating the remote controller, the stage scaffolding 100 can be moved along the floor surface F together with the transport trolley 30 to a predetermined position. At this time, the moving stage scaffolding 100 can be repositioned within the floor M, provided that it does not interfere with other equipment, etc. For example, the stage scaffolding 100 can be repositioned from the first repositioning position R1 shown by the solid line in Figure 7 to the second repositioning position R2 shown by the dotted line.

[0037] Next, the operation of the stage scaffolding travel system 1 described above will be explained in detail based on Figures 1 to 7. The stage scaffolding travel system 1 according to this embodiment includes a work scaffolding unit 10 equipped with scaffolding wheels 13 that roll on the floor surface F, a transport trolley 30 that travels a stage scaffolding 100 formed by integrally connecting multiple work scaffolding units 10, and a connecting jig 40 that is detachably attached to the transport trolley 30 and fixed to the stage scaffolding 100. A key feature is that the stage scaffolding 100 is provided to be able to travel along with the movement of the transport trolley 30.

[0038] In the stage scaffolding travel system 1 according to this embodiment, a stage scaffolding 100 can be provided by combining multiple work scaffolding units 10 so that scaffolding is secured only in the minimum necessary work area within the construction area, rather than covering the entire area. Therefore, in the floor M, it is not necessary to provide stage scaffolding over the entire construction area as in the conventional method, and a stage scaffolding 100 of a predetermined size, fixed to a transport trolley 30 by a connecting jig 40, can be moved together with the transport trolley 30 to other work positions within the floor M. For example, in the case of Figure 7, it is possible to move from the first relocation position R1 to the second relocation position R2. In this embodiment, the number of components constituting the stage scaffolding 100 can be reduced, and the cost of components can be reduced. Furthermore, in this embodiment, by reducing the number of components of the stage scaffolding 100, the effort required to rearrange the stage scaffolding 100 is reduced, thereby improving rearrangement efficiency, securing working time, and shortening the work process.

[0039] Furthermore, in this embodiment, there is a passage space S below the stage scaffolding 100 through which the transport trolley 30 can pass. This configuration allows the transport trolley 30 to pass through the passage space S formed below the stage scaffolding 100 and be positioned at a predetermined fixed position P below the stage scaffolding 100. In other words, by providing a passage space S below the stage scaffolding 100, the transport trolley 30 can be moved in and out of the fixed position P of the stage scaffolding 100. Therefore, for example, when multiple stage scaffolding 100 are provided, multiple stage scaffolding 100 can be moved sequentially and rearranged using a single transport trolley 30, thus reducing the number of transport trolleys 30 required and lowering costs.

[0040] In this embodiment, the transport trolley 30 is positioned in the center of the stage scaffold 100, which is formed by integrating multiple work scaffold units 10, in a plan view. By configuring it in this way, the transport trolley 30 can be fixed in a position where the load balance of the stage scaffold 100, which has a predetermined area, is evenly distributed in the center when viewed from above. Therefore, the stage scaffold 100 can be smoothly transported in all directions by the transport trolley 30.

[0041] In this embodiment, the connecting jig 40 includes a plurality of support columns 41 extending in the vertical direction, a connecting portion 42 that connects the support columns 41 to each other, and a fixing member 43 that is detachably provided on the work scaffolding unit 10. The transport trolley 30 has a support cylinder 33 that detachably supports the lower end portion 41a of the support columns 41. By configuring the system in this way, the lower end portion 41a of the support column 41 is detachably supported by the support cylinder 33 of the transport trolley 30, thereby supporting the connecting jig 40 on the transport trolley 30. Furthermore, the connecting portion 42 of the connecting jig 40 is detachably fixed to the work scaffolding unit 10 via the fixing member 43, thereby allowing the stage scaffolding 100 and the transport trolley 30 to be fixed together as a single unit. Using the connecting jig 40 in this manner allows the transport trolley 30 and the stage scaffolding 100 to be easily attached and detached. For example, the transport trolley 30 can be attached to the stage scaffolding 100 only when changing the stage scaffolding 100.

[0042] In this embodiment, the work scaffolding unit 10 has a first scaffolding board 12 that forms a work surface 12a. The stage scaffolding 100 comprises a plurality of work scaffolding units 10 arranged at predetermined intervals, and a second scaffolding board 20 arranged between the first scaffolding boards 12 of adjacent work scaffolding units 10. By configuring it in this way, a second scaffolding board 20 can be placed between the first scaffolding boards 12 of adjacent work scaffolding units 10, thereby creating a work surface for the stage scaffolding 100 where the first scaffolding boards 12 and the second scaffolding boards 20 are arranged flush with each other. As a result, the number of work scaffolding units 10 can be reduced, making it simpler, lighter, and lowering material costs.

[0043] As described above, the stage scaffolding travel system 1 according to this embodiment can reduce the cost of the components of the stage scaffolding 100, improve the work efficiency for repositioning the stage scaffolding 100, and shorten the work process.

[0044] Although embodiments of the stage scaffolding travel system according to the present invention have been described above, the present invention is not limited to the above embodiments and can be modified as appropriate without departing from the spirit of the invention.

[0045] For example, in the stage scaffolding travel system 1 of the above embodiment, the stage scaffolding 100 is configured such that a second scaffolding board 20 is connected between the first scaffolding boards 12 of the work scaffolding unit 10, but it is not limited to this configuration, and the second scaffolding board 20 can be omitted. Furthermore, although the plan view shape of the stage scaffolding 100 is formed as a rectangle in this embodiment, it may be formed as an L-shape or a triangular shape in plan view along the corners of the wall surface.

[0046] Furthermore, the dimensions, shapes, quantities, and other configurations of each part of the work scaffolding unit 10, the second scaffolding board 20, the transport trolley 30, and the connecting jig 40 are not limited to this embodiment and can be changed as appropriate.

[0047] Furthermore, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, without departing from the spirit of the present invention. [Explanation of Symbols]
