Description

[Technical Field]

[0001] The present invention relates to scaffolding panels for use as side walls of scaffolding. [Background technology]

[0002] Scaffolding panels used as side walls of scaffolding are known. For example, Patent Document 1 discloses a panel structure including a panel used as a side wall for preventing falls of a suspended scaffolding and a panel support mechanism for supporting the panel.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-2703 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, suspended scaffolding is suspended below a structure. The structure from which the suspended scaffolding is suspended may have a support surface that supports the suspended scaffolding that is not horizontal. For example, the support surface may be curved or bent. Generally, the scaffolding planks of the suspended scaffolding are arranged so that they are parallel to the support surface. Therefore, for example, when the suspended scaffolding is installed below an arched bridge, the scaffolding planks are arranged in an arched shape. In this case, the normal directions of adjacent scaffolding planks are different.

[0005] A typical scaffolding panel is rectangular. That is, in a typical scaffolding panel, the widthwise dimension is the same from top to bottom. Therefore, in the case where scaffolding boards are arranged in an arch shape as described above, when multiple rectangular scaffolding panels are erected so as to extend in the normal direction of the scaffolding boards, fan-shaped gaps are generated between adjacent scaffolding panels. Therefore, there has been a demand for scaffolding panels that can fill the fan-shaped gaps in scaffolding where scaffolding boards are arranged in an arch shape.

[0006] An object of the present invention is to provide a scaffolding panel that allows for the construction of a scaffolding without gaps in the side walls, even when the scaffolding boards are arranged in an arch shape. [Means for solving the problem]

[0007] A scaffolding panel according to one embodiment of the present invention is a scaffolding panel that is erected along the edge of a scaffolding board. The scaffolding panel has a rectangular first plate portion extending in the vertical direction, a rectangular second plate portion extending in the vertical direction such that a portion of the width direction overlaps a portion of the first plate portion in the thickness direction, and a connecting portion that connects the first plate portion and the second plate portion so as to be rotatable relative to each other at a position closer to one end in the vertical direction than the vertical center of the area where the first plate portion and the second plate portion overlap (first configuration).

[0008] This allows the first plate portion and the second plate portion to rotate relative to each other around the connecting portion. By rotating the first plate portion and the second plate portion relative to each other, the overlapping area between the first plate portion and the second plate portion on either the upper or lower side of the connecting portion can be increased, and the overlapping area on the other side can be reduced. In other words, the scaffolding panel can be deformed into a fan shape with a narrow width in one direction in the vertical direction and a wide width in the other direction in the vertical direction.

[0009] Therefore, by including a scaffolding panel having the above-mentioned configuration among multiple scaffolding panels arranged horizontally, even when the scaffolding boards are arranged in an arch shape, the multiple scaffolding panels can be erected so as to extend in the normal direction of the scaffolding boards, and the sides facing each other in the width direction of adjacent scaffolding panels can be made to contact each other. Therefore, even when the scaffolding boards are arranged in an arch shape, it is possible to construct scaffolding with no gaps in the side walls.

[0010] Furthermore, the connecting portion is located closer to one end in the vertical direction than the vertical center in the area where the first plate portion and the second plate portion overlap. This allows the length from the rotation center to the other end in the vertical direction to be longer than when the connecting portion is located closer to the vertical center. This configuration allows the amount of change in width of the other end to be larger relative to the amount of change in the rotation angle of the connecting portion. Therefore, a scaffolding panel that can be easily deformed into a fan shape can be realized.

[0011] The scaffolding panel of the first configuration further has a guide portion that guides the relative circumferential movement of the upper region of the first plate portion and the lower region of the second plate portion relative to the connecting portion when the first plate portion and the second plate portion rotate relative to each other around the connecting portion (second configuration).

[0012] This allows the first plate portion and the second plate portion to be rotated while being guided by the guide portion, thereby making it possible to easily change the scaffolding panel into a fan shape.

[0013] In the scaffolding panel of the second configuration, the guide portion includes a through hole provided in one of the first plate portion or the second plate portion so as to extend in a circumferential direction centered on the connecting portion, and a protrusion provided in the other of the first plate portion or the second plate portion so as to be inserted into the through hole and move within the through hole relative to the through hole in the circumferential direction (third configuration).

[0014] This allows for a configuration in which the first plate portion and the second plate portion can be rotated while being guided by a guide portion. Furthermore, the first plate portion and the second plate portion can be rotated relative to each other until a protrusion inserted into a through-hole provided in either the first plate portion or the second plate portion contacts the circumferential end of the through-hole. This limits the circumferential range in which the first plate portion and the second plate portion can rotate relative to each other. Therefore, the first plate portion and the second plate portion can be prevented from rotating relative to each other in the circumferential direction up to an angle at which a gap is created between the first plate portion and the second plate portion.

[0015] In the scaffolding panel of the third configuration, the protrusion has an axial portion that passes through the through hole and a flange portion that is connected to the tip of the axial portion and is larger than the width dimension of the through hole (fourth configuration).

[0016] This prevents the protrusion inserted into the through hole from slipping out of the through hole, and therefore the first plate portion and the second plate portion can rotate relative to each other without separating in the thickness direction.

[0017] In the scaffolding panel of the fourth configuration, the through hole and the protrusion are located closer to the other end in the vertical direction than to the center in the vertical direction of the overlapping region (fifth configuration).

[0018] This allows the through-hole and protrusion to be positioned further apart in the vertical direction than when the through-hole and protrusion are positioned closer to the longitudinal center of the area where the first and second plate portions overlap. In other words, the first and second plate portions can be connected in the thickness direction at two locations that are separated in the vertical direction. This prevents a gap from occurring in the thickness direction between the first and second plate portions.

[0019] In the scaffolding panel of the first configuration, when the first plate portion and the second plate portion are rotated relative to each other so that the other end of the scaffolding panel in the vertical direction is the longest, the portion of the other end of the first plate portion in the vertical direction that overlaps with the second plate portion extends in the circumferential direction about the connecting portion. In the relative rotation state, the portion of the other end of the second plate portion in the vertical direction that overlaps with the first plate portion extends in the circumferential direction about the connecting portion. The length from the connecting portion to the portion of the other end of the first plate portion that extends in the circumferential direction is the same as the length from the connecting portion to the portion of the other end of the second plate portion that extends in the circumferential direction (sixth configuration).

[0020] As a result, when the scaffolding panel is deformed into a fan shape with the widest width at the other end in the vertical direction, the position of the other end of the first plate portion in the vertical direction that is located within the range where the second plate portion overlaps can be aligned with the position of the other end of the second plate portion in the vertical direction that is located within the range where the first plate portion overlaps. Therefore, in the relative rotation state, it is possible to prevent the other end of the first plate portion in the vertical direction from protruding from the other end of the second plate portion in the vertical direction, or the other end of the second plate portion from protruding from the other end of the first plate portion, as viewed in the thickness direction.

[0021] A scaffolding according to one embodiment of the present invention comprises a scaffolding panel described in any one of the first to sixth configurations, which is erected along the edge of the scaffolding board (seventh configuration).

[0022] By replacing at least one of the scaffolding panels that make up the side walls of the scaffolding with a scaffolding panel having the above-mentioned configuration, it is possible to eliminate gaps between adjacent scaffolding panels in a scaffolding where the scaffolding boards are arranged in an arch shape, thereby providing a scaffolding with no gaps in the side walls. [Effects of the Invention]

[0023] A scaffolding panel according to one embodiment of the present invention has a first plate portion, a second plate portion, and a connecting portion that connects the first plate portion and the second plate portion so as to be rotatable relative to each other at a position closer to one end in the vertical direction than the vertical center in the area where the first plate portion and the second plate portion overlap.

[0024] This makes it possible to provide a scaffolding panel that allows for the construction of scaffolding with no gaps in the side walls. [Brief explanation of the drawings]

[0026] 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 14 extends is referred to as the horizontal direction, and the thickness direction of the scaffolding plank 14 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 it functions as the suspended scaffolding 1. The up-down direction is the vertical direction or a direction perpendicular to the horizontal direction.

[0028] In the following description, the direction in which the scaffolding board 14 is located relative to the scaffolding panel 2 will be referred to as the front, and the opposite direction will be referred to as the rear.

[0029] Furthermore, in the following description, the expressions "fix," "connect," and "attach" (hereinafter referred to as "fixing") 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, the expression "fixing" includes both direct and indirect fixing of members to each other.

[0030] (Scaffolding configuration) With reference to Figures 1 and 2, an exemplary scaffolding having a variable scaffolding panel 4, which is a scaffolding panel 2 according to this embodiment, will be described. In this embodiment, a case will be described in which the scaffolding having the variable scaffolding panel 4 is a suspended scaffolding. Figure 1 is a perspective view showing the general configuration of a suspended scaffolding 1 on which a variable scaffolding panel 4 is installed. Figure 1 shows a part of the suspended scaffolding 1. Figure 2 is a diagram showing the arrangement of the scaffolding panel 2. Figure 2 shows the suspended scaffolding 1 as viewed from the rear. Note that the variable scaffolding panel 4 may be used in a suspended scaffold having a configuration different from that of the suspended scaffolding shown in Figures 1 and 2. The variable scaffolding panel 4 may also be used in a scaffold that is installed on the ground.

[0031] As shown in Figure 2, the suspended scaffolding 1 is suspended below a structure T using suspension members 18 such as wires and chains. The suspended scaffolding 1 is used in work environments where it is difficult to set up scaffolding on the ground, such as when constructing a structure such as a bridge.

[0032] As shown in Figure 1, the suspended scaffolding 1 has a plurality of scaffolding panels 2, a plurality of horizontal members 11, a plurality of vertical supports 12, a beam member 13, a scaffolding board 14, a panel positioning member 15, a connecting member 16, a panel fixing member 17, and a suspension member 18.

[0033] The multiple horizontal members 11 are arranged to extend in one horizontal direction and in a direction intersecting the one horizontal direction. The multiple horizontal members 11 are connected to each other by connecting members 16 and configured into a frame shape extending horizontally. The multiple horizontal members 11 support scaffolding planks 14. Some of the multiple horizontal members 11 are also connected to hanging members 18 such as wires and chains that suspend the suspended scaffolding 1 below the structure T.

[0034] The multiple vertical struts 12 are columnar members extending in the vertical direction. The multiple vertical struts 12 extend in the vertical direction of the suspended scaffolding 1. The multiple vertical struts 12 are connected to parts of the horizontal members 11 by connecting members 16.

[0035] The beam members 13 are columnar members extending horizontally. The beam members 13 extend horizontally between adjacent vertical supports 12 among the multiple vertical supports 12. The longitudinal ends of the beam members 13 are connected to the vertical supports 12 by connecting members 16.

[0036] The scaffolding board 14 is a plate-like member that extends horizontally. The scaffolding board 14 is supported by the horizontal members 11. The scaffolding board 14 is fixed to the horizontal members 11 by fixing members (not shown). The scaffolding board 14 forms the floor surface of the work area of ​​the suspended scaffolding 1. The scaffolding board 14 serves as a work platform on which workers perform work and as a passageway along which workers move. Tools and the like used in work can also be placed on the scaffolding board 14.

[0037] The panel positioning member 15 extends horizontally. The panel positioning member 15 is arranged along the edge of the scaffolding board 14. In this embodiment, the panel positioning member 15 has a horizontally extending groove that opens upward. One end and the other end in the longitudinal direction of the panel positioning member 15 are each fixed to the vertical support 12. The panel positioning member 15 positions the scaffolding panel 2 in the up and down direction relative to the scaffolding board 14.

[0038] As shown in Figures 1 and 2, the scaffolding panel 2 is erected along the edge of the scaffolding board 14. The lower end of the scaffolding panel 2 is housed in a groove in the panel positioning member 15. The scaffolding panel 2 forms the side wall W of the suspended scaffolding 1. The scaffolding panel 2 prevents parts, components, etc. used in the suspended scaffolding 1 from falling outside the suspended scaffolding 1 and prevents dust, etc. from being discharged outside the suspended scaffolding 1.

[0039] The suspended scaffolding 1 has a plurality of scaffolding panels 2. In this embodiment, the plurality of scaffolding panels 2 are installed behind the vertical supports 12 and beam members 13. The plurality of scaffolding panels 2 are fixed to the beam members 13 by panel fixing members 17 attached to the beam members 13.

[0040] In this embodiment, multiple scaffolding panels 2 are arranged horizontally with no gaps between them. That is, the widthwise end of one scaffolding panel 2 is in contact with the widthwise end of another scaffolding panel 2 adjacent to the scaffolding panel 2. In this embodiment, the scaffolding panels 2 have rib portions that protrude forward at both widthwise ends. The rib portions of adjacent scaffolding panels 2 are in contact with each other. Panel fixing members 17 attached to the beam members 13 connect the rib portions to each other.

[0041] In this embodiment, the scaffolding panels 2 include standard scaffolding panels 3, which are general scaffolding panels 2, and variable scaffolding panels 4, whose shapes can be changed. The variable scaffolding panels 4 are the scaffolding panels of the present invention.

[0042] The standard scaffolding panel 3 is a rectangular plate when viewed in the thickness direction. The standard scaffolding panel 3 has the same widthwise length from top to bottom. The adjustable scaffolding panel 4 changes shape between a rectangular shape and a fan shape when viewed in the thickness direction.

[0043] As shown in Figure 2, the structure T from which the suspended scaffolding 1 is suspended may have a curved support surface that supports the suspended scaffolding 1. For example, the suspended scaffolding 1 may be installed below an arch-shaped bridge. In the suspended scaffolding 1 installed below an arch-shaped bridge, the scaffolding planks 14 are arranged in an arch shape. In this case, the normal directions of the scaffolding planks 14 relative to the vertical direction may differ between adjacent scaffolding planks 14. As a result, fan-shaped gaps that become wider as they extend upward may occur between adjacent scaffolding panels 2 arranged horizontally. In other words, gaps may form in the side walls W of the suspended scaffolding 1.

[0044] The adjustable scaffolding panel 4 changes into a fan shape. Therefore, by installing at least one adjustable scaffolding panel 4 on the suspended scaffolding 1, in a suspended scaffolding 1 in which the scaffolding boards 14 are arranged in an arch shape, the widthwise end of the adjustable scaffolding panel 4 can come into contact with the widthwise end of the standard scaffolding panel 3 adjacent to the adjustable scaffolding panel 4. Therefore, a suspended scaffolding 1 can be provided in which there are no gaps in the side walls W.

[0045] (Detailed configuration of the adjustable scaffolding panel) Next, the adjustable scaffolding panel 4 will be described in detail with reference to Fig. 1 and Fig. 3 to Fig. 7. Fig. 3 is a perspective view of the rectangular adjustable scaffolding panel 4 as seen from one side in the thickness direction. Fig. 4 is a perspective view of the rectangular adjustable scaffolding panel 4 as seen from the other side in the thickness direction. Fig. 5 is a perspective view of the fan-shaped adjustable scaffolding panel 4 as seen from one side in the thickness direction. Fig. 6 is a perspective view of the fan-shaped adjustable scaffolding panel 4 as seen from the other side in the thickness direction. Fig. 7 is a diagram illustrating deformation of the adjustable scaffolding panel 4.

[0046] As shown in Figures 3 to 6, the adjustable scaffolding panel 4 has a main body 41 extending in the vertical direction and a pair of rib portions 42. The main body 41 has one end 41a in the vertical direction and the other end 41b in the vertical direction, which respectively constitute both ends in the vertical direction. Hereinafter, the end located on the lower side in each figure will be referred to as one end 41a, and the end located on the upper side will be referred to as the other end 41b. As shown in Figure 1, in this embodiment, the adjustable scaffolding panel 4 is installed on the suspended scaffolding 1 in an orientation where one end 41a is located downward. Note that the adjustable scaffolding panel 4 may also be installed on the suspended scaffolding 1 in an orientation where one end 41a is located upward.

[0047] As shown in Figures 3 to 6, the main body 41 has one surface in the thickness direction and the other surface in the thickness direction. Hereinafter, the surface from which the pair of rib portions 42 protrude will be referred to as the front surface 41c, and the opposite surface will be referred to as the back surface 41d. As shown in Figure 1, in this embodiment, the adjustable scaffolding panel 4 is installed on the suspended scaffolding 1 with the front surface 41c facing forward. Note that the adjustable scaffolding panel 4 may also be installed on the suspended scaffolding 1 with the back surface 41d facing forward.

[0048] As shown in Figures 3 to 6, the pair of rib portions 42 protrude in the thickness direction from both widthwise ends on the surface 41c side of the main body portion 41. The pair of rib portions 42 each extend in the vertical direction along the widthwise end portions of the main body portion 41. As shown in Figure 1, the rib portions 42 come into contact with the rib portions of other scaffolding panels 2 adjacent to the adjustable scaffolding panel 4 in the horizontal direction. The rib portions 42 of the adjustable scaffolding panel 4 and the rib portions of other scaffolding panels 2 adjacent to the adjustable scaffolding panel 4 are connected by panel fixing members 17 attached to the beam members 13.

[0049] 3 to 6, the main body 41 of the adjustable scaffolding panel 4 is composed of a first plate main body 51 of the first plate 5 and a second plate main body 61 of the second plate 6, which will be described later. The pair of rib portions 42 of the adjustable scaffolding panel 4 is composed of a first plate rib portion 52 of the first plate 5 and a second plate rib portion 62 of the second plate 6, which will be described later.

[0050] Specifically, the adjustable scaffolding panel 4 has a first plate portion 5, a second plate portion 6, a connecting portion 7, and a guide portion 8.

[0051] The first plate portion 5 and the second plate portion 6 are each a rectangular plate extending in the vertical direction. A portion of the first plate portion 5 in the width direction and a portion of the second plate portion 6 in the width direction overlap in the thickness direction. In this embodiment, the second plate portion 6 is located on the surface 51c side of the first plate portion 5.

[0052] The first plate portion 5 has a first plate main body portion 51 and a first plate rib portion 52. The first plate main body portion 51 constitutes a part of the main body portion 41 of the adjustable scaffolding panel 4. One vertical end 51a of the first plate portion 5 constitutes a part of one vertical end 41a of the main body portion 41 of the adjustable scaffolding panel 4. The other vertical end 51b of the first plate main body portion 51 constitutes a part of the other vertical end 41b of the main body portion 41 of the adjustable scaffolding panel 4.

[0053] 7, the other end 51b of the first plate main body 51 in the up-down direction has a portion 53 at its tip on the second plate 6 side that extends in the circumferential direction around the connecting portion 7. In other words, of the widthwise ends of the first plate 5, the up-down length of the end on the side where the second plate 6 overlaps is shorter than the up-down length of the end on the opposite widthwise side.

[0054] 3 to 6, of the thickness directions of the first plank main body 51, the front surface 51c, which is the surface on the second plank 6 side, constitutes a part of the front surface 41c of the main body 41 of the adjustable scaffolding panel 4. Of the thickness directions of the first plank main body 51, the back surface 51d, which is the surface opposite to the second plank 6 side, constitutes a part of the back surface 41d of the main body 41 of the adjustable scaffolding panel 4.

[0055] The first plate rib portion 52 protrudes forward from the tip of the end portion in the width direction of the first plate main body portion 51 that is not overlapped by the second plate portion 6. The first plate rib portion 52 constitutes one of the pair of rib portions 42 of the adjustable scaffolding panel 4.

[0056] The second plate portion 6 is located on the surface 51c side of the first plate portion 5. The second plate portion 6 has a second plate main body portion 61 and a second plate rib portion 62. The second plate main body portion 61 forms part of the main body portion 41 of the adjustable scaffolding panel 4. One vertical end 61a of the second plate main body portion 61 forms part of one vertical end 41a of the main body portion 41 of the adjustable scaffolding panel 4. The other vertical end 61b of the second plate main body portion 61 forms part of the other vertical end 41b of the main body portion 41 of the adjustable scaffolding panel 4.

[0057] 7, the other vertical end 61b of the second plate main body portion 61 has a portion 63 at its tip on the first plate portion 5 side that extends in the circumferential direction around the connecting portion 7. In other words, of the widthwise ends of the second plate portion 6, the vertical length of the end on the side where the first plate portion 5 overlaps is shorter than the vertical length of the end on the opposite side in the width direction. The length from the connecting portion 7 to the circumferentially extending portion 63 is the same as the length from the connecting portion 7 to the circumferentially extending portion 53 of the first plate main body portion 51.

[0058] Of the thickness-wise faces of the second plank main body 61, the front face 61c, which is the face opposite to the first plank 5, constitutes part of the front face 41c of the main body 41 of the adjustable scaffolding panel 4. Of the thickness-wise faces of the second plank main body 61, the back face 61d, which is the face on the first plank 5 side, constitutes part of the back face 41d of the main body 41 of the adjustable scaffolding panel 4.

[0059] 3 to 6, the second plate rib portion 62 protrudes forward from the tip of one of the widthwise ends of the second plate main body portion 61 that is not overlapped by the first plate portion 5. The second plate rib portion 62 constitutes the other of the pair of rib portions 42 of the adjustable scaffolding panel 4.

[0060] 3 to 6, the connecting portion 7 connects the first plate portion 5 and the second plate portion 6 to be relatively rotatable at a position closer to one end 41a in the vertical direction than to the vertical center of the area where the first plate portion 5 and the second plate portion 6 overlap in the adjustable scaffolding panel 4. In other words, the first plate portion 5 and the second plate portion 6 rotate relatively around the connecting portion 7.

[0061] By rotating the first plate portion 5 and the second plate portion 6 relative to each other, the overlapping area between the first plate portion 5 and the second plate portion 6 can be increased on either the upper or lower side of the connecting portion 7, and the overlapping area can be decreased on the other side. In other words, the adjustable scaffolding panel 4 can be deformed into a fan shape in which one width in the vertical direction is wider than the other width. Therefore, the adjustable scaffolding panel 4 can be changed between a rectangular shape shown in Figures 3 and 4 and a fan shape shown in Figures 5 and 6.

[0062] As shown in FIG. 1 , in this embodiment, the adjustable scaffolding panel 4 is installed on the suspended scaffolding 1 in a position where one end 41 a is positioned downward. Therefore, the connecting portion 7 connects the first plate portion 5 and the second plate portion 6 at a position near the lower end of the adjustable scaffolding panel 4 so as to be rotatable relative to each other. Therefore, the adjustable scaffolding panel 4 transforms into a fan-shaped scaffolding panel whose width increases as it extends upward. As described above, the adjustable scaffolding panel 4 may also be installed on the suspended scaffolding 1 in a position where one end 41 a is positioned upward. In this case, the connecting portion connects the first plate portion and the second plate portion at a position near the upper end so as to be rotatable relative to each other. In other words, the adjustable scaffolding panel transforms into a fan-shaped scaffolding panel whose width increases as it extends downward.

[0063] The configuration of the connecting portion 7 is not particularly limited as long as it can connect the first plate portion 5 and the second plate portion 6 so that they can rotate relative to each other. For example, the connecting portion 7 may be a shaft-shaped member that passes through the area where the first plate portion 5 and the second plate portion 6 overlap in the thickness direction. The shaft-shaped member may be, for example, a fastening member such as a bolt and a nut.

[0064] In this embodiment, as shown in Figure 7, when the first plate portion 5 and the second plate portion 6 are rotated relative to each other so that the other vertical end 41b of the variable scaffolding panel 4 is the longest, the circumferentially extending portion 53 of the other vertical end 51b of the first main body portion 51 and the circumferentially extending portion 63 of the other vertical end 61b of the second main body portion 61 overlap in the thickness direction.

[0065] As described above, the circumferentially extending portion 53 of the first body portion 51 extends in the circumferential direction centered on the connecting portion 7. The circumferentially extending portion 63 of the second body portion 61 extends in the circumferential direction centered on the connecting portion 7. The length from the connecting portion 7 to the circumferentially extending portion 53 of the first body portion 51 is the same as the length from the connecting portion 7 to the circumferentially extending portion 63 of the second plate body portion 61.

[0066] As a result, when the adjustable scaffold panel 4 is deformed into a fan shape with the other end 41b in the vertical direction being the widest, the vertical position of the portion 53 of the other end 51b in the vertical direction of the first plank main body portion 51 that is located within the range where the second plank main body portion 61 overlaps can be aligned with the vertical position of the portion 63 of the other end 61b in the vertical direction of the second plank main body portion 61 that is located within the range where the first plank main body portion 51 overlaps. Therefore, in this state, when viewed in the thickness direction, it is possible to prevent the other end 51b in the vertical direction of the first plank main body portion 51 from protruding from the other end 61b in the vertical direction of the second main body portion 61, and the other end 61b of the second plank main body portion 61 from protruding from the other end 51b of the first plank main body portion 51.

[0067] As shown in Figures 3 to 6, when the first plate portion 5 and the second plate portion 6 rotate relative to each other around the connecting portion 7, the guide portion 8 guides the relative circumferential movement of the upper region of the first plate portion 5 and the lower region of the second plate portion 6 relative to the connecting portion 7.

[0068] The configuration of the guide portion 8 is not particularly limited as long as it can guide the relative movement of the region of the first plate portion 5 and the region of the second plate portion 6 .

[0069] In this embodiment, as shown in Fig. 4, the guide portion 8 includes a protruding portion 81 provided on the first plate main body portion 51 and a through hole 82 provided on the second plate main body portion 61. The protruding portion 81 protrudes from the surface 51c of the first plate main body portion 51 toward the second plate main body portion 61. The through hole 82 extends in the circumferential direction around the connecting portion 7. The protruding portion 81 is inserted into the through hole 82 and moves within the through hole 82 relative to the through hole 82 in the circumferential direction.

[0070] In this embodiment, the protrusion 81 has a shaft-shaped shaft portion 81a that passes through the through hole 82, and a flange portion 81b connected to the tip of the shaft portion 81a. The flange portion 81b is larger than the width direction dimension of the through hole 82. In this embodiment, the shaft-shaped shaft portion 81a is a bolt, and the flange portion 81b is a nut. This makes it possible to prevent the protrusion 81 inserted into the through hole 82 from slipping out of the through hole 82 in the thickness direction of the adjustable scaffolding panel 4.

[0071] In this embodiment, the through hole 82 extends in the circumferential direction. Therefore, the first plate portion 5 and the second plate portion 6 can be rotated relative to each other until the protrusion 81 of the first plate portion 5 inserted into the through hole 82 comes into contact with the circumferential end of the through hole 82. In other words, the length of the through hole 82 determines the range of rotation of the second plate portion 6 relative to the first plate portion 5.

[0072] In addition, the through hole 82 can prevent the first plate portion 5 and the second plate portion 6 from rotating relative to each other in the circumferential direction to an angle at which a gap is created between the upper end of the first plate portion 5 and the upper end of the second plate portion 6.

[0073] In this embodiment, the protrusion 81 and the through-hole 82 are located near the other end 41b of the area where the first plate portion 5 and the second plate portion 6 of the adjustable scaffolding panel 4 overlap.

[0074] This makes it possible to increase the length from the rotation center to the other end of the first plate portion 5 and the second plate portion 6 in the vertical direction compared to when the connecting portion 7 is located closer to the center in the vertical direction. In other words, this configuration makes it possible to increase the amount of change in the width of the other end 41b relative to the amount of change in the rotation angle of the connecting portion 7. Therefore, it is possible to realize a variable scaffolding panel 4 that can easily be deformed into a fan shape.

[0075] In this embodiment, the protrusion 81 is provided on the first plate portion 5, and the through hole 82 is provided on the second plate portion 6. However, the through hole may be provided on the first plate portion, and the protrusion may be provided on the second plate portion.

[0076] As described above, the adjustable scaffolding panel 4 according to this embodiment is a scaffolding panel that is erected along the edge of the scaffolding board 14. The adjustable scaffolding panel 4 has a rectangular first plate portion 5 that extends in the vertical direction, a rectangular second plate portion 6 that extends in the vertical direction so that a portion of the width direction overlaps a portion of the width direction of the first plate portion 5 in the thickness direction, and a connecting portion 7 that connects the first plate portion 5 and the second plate portion 6 so as to be rotatable relative to each other at a position closer to one end in the vertical direction than the center in the vertical direction in the area where the first plate portion 5 and the second plate portion 6 overlap.

[0077] This allows the first plate portion 5 and the second plate portion 6 to rotate relatively around the connecting portion 7. By rotating the first plate portion 5 and the second plate portion 6 relative to each other, the overlapping area between the first plate portion 5 and the second plate portion 6 on either the upper or lower side of the connecting portion 7 can be increased, and the overlapping area on the other side can be reduced. In other words, the adjustable scaffolding panel 4 can be deformed into a fan shape that is narrow in one direction in the vertical direction and wide in the other direction in the vertical direction.

[0078] Therefore, by including an adjustable scaffolding panel 4 among multiple scaffolding panels 2 arranged horizontally, even when the scaffolding boards 14 are arranged in an arch shape, multiple scaffolding panels 2 can be erected so as to extend in the normal direction of the scaffolding boards 14, while allowing the sides of adjacent scaffolding panels 2 facing each other in the width direction to come into contact with each other. Therefore, even when the scaffolding boards 14 are arranged in an arch shape, it is possible to construct scaffolding with no gaps in the side walls W.

[0079] Furthermore, the connecting portion 7 is located closer to the one end 41a in the vertical direction than to the vertical center in the area where the first plate portion 5 and the second plate portion 6 overlap. This allows the length from the rotation center to the other end 41b in the vertical direction to be longer than when the connecting portion is located closer to the vertical center. This configuration allows the amount of change in the width of the other end 41b to be greater relative to the amount of change in the rotation angle of the connecting portion 7. Therefore, it is possible to realize a variable scaffolding panel 4 that can easily be deformed into a fan shape.

[0080] In this embodiment, the variable scaffolding panel 4 has a guide portion 8 that guides the relative circumferential movement of the upper region of the first plate portion 5 and the second plate portion 6 relative to the connecting portion 7 and the lower region of the first plate portion 5 and the second plate portion 6 relative to the connecting portion 7 when the first plate portion 5 and the second plate portion 6 rotate relative to each other around the connecting portion 7.

[0081] This allows the first plate portion 5 and the second plate portion 6 to rotate while being guided by the guide portion 8. Therefore, the adjustable scaffolding panel 4 can be easily changed into a fan shape.

[0082] In this embodiment, the guide portion 8 includes a through hole 82 provided in one of the first plate portion 5 or the second plate portion 6 so as to extend circumferentially around the connecting portion 7, and a protrusion 81 provided in the other of the first plate portion 5 or the second plate portion 6 so as to be inserted into the through hole 82 and move circumferentially relative to the through hole 82 within the through hole 82.

[0083] This makes it possible to realize a configuration in which the first plate portion 5 and the second plate portion 6 can be rotated while being guided by the guide portion 8. Furthermore, the first plate portion 5 and the second plate portion 6 can be rotated relative to each other until the protrusion 81 inserted into the through hole 82 provided in either the first plate portion 5 or the second plate portion 6 comes into contact with the circumferential end of the through hole 82. This makes it possible to limit the circumferential range in which the first plate portion 5 and the second plate portion 6 can rotate relative to each other. Therefore, it is possible to prevent the first plate portion 5 and the second plate portion 6 from rotating relative to each other in the circumferential direction up to an angle at which a gap is created between the first plate portion 5 and the second plate portion 6.

[0084] In this embodiment, the protrusion 81 has a shaft portion 81a that passes through the through-hole 82, and a flange portion 81b that is connected to the tip of the shaft portion 81a and is larger than the dimension of the through-hole 82 in the width direction.

[0085] This prevents the protrusion 81 inserted into the through-hole 82 from slipping out of the through-hole 82. Therefore, the first plate portion 5 and the second plate portion 6 can rotate relative to each other without separating in the thickness direction.

[0086] In this embodiment, the through hole 82 and the protrusion 81 are located closer to the other end 41b in the vertical direction than to the center in the region where the first plate portion 5 and the second plate portion 6 overlap.

[0087] As a result, compared to when the through hole and protrusion are located closer to the longitudinal center of the area where the first plate portion 5 and the second plate portion 6 overlap, the connecting portion 7 that connects the first plate portion 5 and the second plate portion 6 so that they can rotate relative to each other, and the through hole 82 and protrusion 81 can be positioned further apart in the vertical direction. In other words, the first plate portion 5 and the second plate portion 6 can be connected in the thickness direction at two locations that are separated in the vertical direction. This makes it possible to prevent a gap from occurring in the thickness direction between the first plate portion 5 and the second plate portion 6.

[0088] In this embodiment, in a state in which the first plate portion 5 and the second plate portion 6 are rotated relative to each other so that the other end 41b in the vertical direction of the adjustable scaffolding panel 4 is the longest, a portion 53 of the other end 51b in the vertical direction of the first plate main body portion 51 of the first plate portion 5 that overlaps with the second plate portion 6 extends in the circumferential direction centered on the connecting portion 7. In the above-mentioned relative rotation state, a portion of the other end 61b in the vertical direction of the second plate main body portion 61 of the second plate portion 6 that overlaps with the first plate portion 5 extends in the circumferential direction centered on the connecting portion 7. The length from the connecting portion 7 to the portion 53 of the other end 51b of the first plate main body portion 51 that extends in the circumferential direction is the same as the length from the connecting portion 7 to the portion 63 of the other end 61b of the second main body portion 61 that extends in the circumferential direction.

[0089] As a result, when the adjustable scaffold panel 4 is deformed into a fan shape with the other end 41b in the vertical direction being the widest, the vertical position of the portion 53 of the other end 51b in the vertical direction of the first plank main body portion 51 that is located within the range where the second plank main body portion 61 overlaps can be aligned with the vertical position of the portion 63 of the other end 61b in the vertical direction of the second plank main body portion 61 that is located within the range where the first plank main body portion 51 overlaps. Therefore, in this state, when viewed in the thickness direction, it is possible to prevent the other end 51b in the vertical direction of the first plank main body portion 51 from protruding from the other end 61b in the vertical direction of the second main body portion 61, and the other end 61b of the second plank main body portion 61 from protruding from the other end 51b of the first plank main body portion 51.

[0090] In addition, the suspended scaffolding 1 according to this embodiment has a scaffolding board 14 and a variable scaffolding panel 4 erected along the edge of the scaffolding board 14.

[0091] By replacing at least one of the multiple scaffolding panels 2 that make up the side wall W of the suspended scaffolding 1 with the adjustable scaffolding panel 4 having the above-mentioned configuration, it is possible to eliminate gaps between adjacent scaffolding panels 2 in the suspended scaffolding 1 in which the scaffolding planks 14 are arranged in an arch shape. Therefore, it is possible to provide a suspended scaffolding 1 with no gaps in the side wall W.

[0092] (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.

[0093] In the above embodiment, an example has been described in which the adjustable scaffolding panel 4 is installed on the suspended scaffolding 1 in order to construct a gap-free side wall W in a suspended scaffolding 1 in which the scaffolding planks 14 are arranged in an arch shape. However, the adjustable scaffolding panel may be installed on the scaffolding for other purposes. For example, the adjustable scaffolding panel may be set for the purpose of forming a fan-shaped gap in the side wall W of the scaffolding. The adjustable scaffolding panel may also be installed on a scaffold in which the scaffolding planks are arranged horizontally.

[0094] In the above embodiment, the suspended scaffolding 1 has standard scaffolding panels 3 and adjustable scaffolding panels 4 as the scaffolding panels 2. However, the suspended scaffolding may have only adjustable scaffolding panels as the scaffolding panels.

[0095] In the above embodiment, the plurality of scaffolding panels 2 are arranged behind the vertical struts 12 and beam members 13. However, the plurality of scaffolding panels may also be arranged in front of the vertical struts and beam members.

[0098] In the above embodiment, the second plate portion 6 has a second plate rib portion 62 that protrudes in the thickness direction from the tip of the end portion that is not overlapped with the first plate portion 5. However, the second plate portion does not have to have a second plate rib portion. The second plate portion may have a rib portion that protrudes in the thickness direction from a position other than the tip of the end portion.

[0099] In the above embodiment, the second plate portion 6 is located on the front surface 51c side of the first plate portion 5. However, the second plate portion may be located on the rear surface side of the first plate portion.

[0100] In the embodiment, the protrusion 81 and the through hole 82 are located near the other end 41b of the overlapping area between the first plate portion 5 and the second plate portion 6 in the adjustable scaffolding panel 4. However, the protrusion and the through hole may be located at other positions in the overlapping area.

[0101] In the above embodiment, the other end 51b of the first plate body 51 in the vertical direction has a portion 53 at its tip on the second plate body 6 side that extends in the circumferential direction around the connecting portion 7. However, the other end 51b of the first plate body 51 in the vertical direction does not have to have a portion that extends in the circumferential direction around the connecting portion. The other end may extend horizontally from one end in the width direction to the other end in the width direction.

[0102] In the above embodiment, the other end 61b of the second plate body 61 in the vertical direction has a portion 63 at its tip on the first plate body 5 side that extends in the circumferential direction about the connecting portion 7. However, the other end 61b of the second plate body 61 in the vertical direction does not have to have a portion that extends in the circumferential direction about the connecting portion. The other end may extend horizontally from one end in the width direction to the other end in the width direction. [Industrial Applicability]
