  The suspension scaffold is installed below or on the side of the structure as a scaffold for a worker to perform repair work or the like on the structure such as an expressway or a bridge. As shown in FIGS. 1 and 2, the fixing structure 1 according to the first embodiment is used by being fixed to a balustrade 11 of a structure. In the suspended scaffolding by the fixed structure 1, the operator can perform repair work such as painting the wall surface of the balustrade 11. The balustrade (railing) in the present specification is an end structure that protrudes upward at the edge of a structure such as a highway or a bridge in order to prevent a vehicle or a person from falling, and at least the outside (surface facing the road). It has a wall surface as the outer surface on the non-side.

  The fixing structure 1 includes a scaffold plate 2, first horizontal single tubes 3 and 4, a first vertical single tube 5, a first fixture 6, an L-shaped member 7, and a second vertical single unit. A tube 8, a second horizontal single tube 9, and a third vertical single tube 10 are provided. Although a plurality of these members are provided as shown in FIG. 1, the number of each component shown in FIG. 1 and the like is merely an example, and the number is not limited to these numbers. In the said structure, while arrange | positioning the side surface of the 1st vertical single pipe | tube 5 so that the outer surface 11a of the balustrade 11 may be followed, the end 5e of the 1st vertical single pipe | tube 5 was made to contact | abut to the upper surface of the scaffold board 2. In the state, the first vertical single tube 5 is fixed to the first horizontal single tube 4. Thereby, the fixed structure 1 is formed.

  The scaffold board 2 is a plate-like member that serves as a base for workers to perform work. Each scaffold plate 2 in the first embodiment has a rectangular outer shape (cross section) having a longitudinal direction A and a short direction B perpendicular to the longitudinal direction A. As shown in FIG. 1, the plurality of scaffolding plates 2 are arranged side by side along the short-side direction B, with sides extending along the longitudinal direction A being adjacent to each other. That is, the arrangement direction of the scaffolding plate 2 coincides with the short direction B of the scaffolding plate 2. In other words, the arrangement direction of the scaffolding plate 2 coincides with the direction in which the balustrade 11 extends along the structure.

  The first horizontal single tubes 3 and 4 are pipes arranged in the horizontal direction that directly or indirectly support the plurality of scaffolding plates 2 from the lower side. As shown in FIGS. 1 to 3, the first horizontal single tube 3 is arranged to extend in the B direction, and the first horizontal single tube 4 is arranged in the A direction below the first horizontal single tube 3. It is arranged to extend. The first horizontal single tube 3 and the first horizontal single tube 4 are orthogonal to each other in plan view, and the intersecting portion is fixed using, for example, an orthogonal clamp. Each scaffold plate 2 is directly supported by the first horizontal single tube 3 and indirectly supported by the first horizontal single tube 4 via the first horizontal single tube 3.

  The first vertical single pipe 5 is a pipe arranged so as to extend along a vertical direction C that is a direction perpendicular to a horizontal plane including the longitudinal direction A and the short direction B. As shown in FIGS. 1 and 2, the lower end 5 e of the first vertical single pipe 5 is disposed so as to contact one upper surface of the scaffold plate 2. One end side (lower side) of the first vertical single tube 5 that is in contact with the scaffold plate 2 is fixed to the first horizontal single tube 4 by the first fixture 6. The other end side (upper side) of the first vertical single tube 5 is fixed to a second horizontal single tube 9 described later. The side surface of the first vertical single tube 5 is in close contact with the outer surface 11 a of the balustrade 11.

  The first fixture 6 is a fixture that fixes the first vertical single tube 5 to the first horizontal single tube 4. As shown in FIG. 1, the first fixture 6 is connected to the first vertical single tube 5 through the gap between the scaffold plate 2 that contacts one end 5 e of the first vertical single tube 5 and the adjacent scaffold plate 2. The first horizontal single tube 4 is fixed. The structure of the 1st fixing tool 6 is demonstrated using FIG.

  As shown in FIG. 4, the first fixture 6 includes first and second gripping portions 80 and 81, first and second shaft portions 82 and 83, and a distance adjusting portion 84.

  Single clamps are used as the first and second gripping portions 80 and 81. The first and second shaft portions 82 and 83 are rod-shaped members extending in the coaxial direction (vertical direction C). One end sides of the first and second shaft portions 82 and 83 are connected to the screw connection portions 80a and 81a of the first and second grip portions 80 and 81, respectively. The first and second gripping portions 80 and 81 are rotatable with respect to the first and second shaft portions 82 and 83 around the screw connection portions 80a and 81a. The other end sides of the first and second shaft portions 82 and 83 have screw threads and are screw-connected to the distance adjusting portion 84. The distance adjusting portion 84 has a screw groove for receiving the threads of the first and second shaft portions 82 and 83 on the inner side, and a relative vertical distance between the first and second shaft portions 82 and 83. Can be adjusted.

  In such a configuration, the relative position of the first and second shaft portions 82 and 83 in the axial direction can be adjusted by rotating the distance adjusting portion 84 (arrow D). This adjusts the relative vertical distance between the single tubes gripped by the first and second gripping portions 80 and 81, that is, the first vertical single tube 5 and the first horizontal single tube 4 described above. be able to.

  Returning to FIGS. 1 to 3, an L-shaped member 7 is attached to the end of the first horizontal single tube 4. On the L-shaped member 7, a scaffold plate 13 different from the scaffold plate 2 is placed at a position adjacent to the plurality of scaffold plates 2. Although not shown in FIG. 1, a base board 14 is attached to the upper side surface of the L-shaped member 7 (see FIGS. 2 and 3). A third vertical single tube 10 extending in the vertical direction C is attached to the upper end portion of the L-shaped member 7. By providing the third vertical single tube 10 and the L-shaped member 7, it is possible to attach and arrange a fall prevention panel or net to these members. That is, the L-shaped member 7, the third vertical single tube 10, the scaffold board 13 and the skirting board 14 function as a fall prevention mechanism.

  In the first horizontal single tube 4, the end opposite to the side on which the L-shaped member 7 is attached is fixed to the H-section steel 12. The H-section steel 12 is a section steel having a “H” cross section attached below the balustrade 11. In the first embodiment, the first horizontal single pipe 4 is fixed to the H-shaped steel 12 using the steel clamp 48 (FIG. 2).

  The second horizontal single tube 9 is a pipe that extends in the horizontal direction (A direction) and is fixed to each of the first vertical single tube 5 and the third vertical single tube 10 described above by orthogonal clamps. The second horizontal single tube 9 is disposed along the upper surface 11 b of the balustrade 11. Further, a second vertical single pipe 8 is fixed to the second horizontal single pipe 9 by an orthogonal clamp. The second vertical single pipe 8 extends in the vertical direction C and is disposed along the inner side surface 11 c of the balustrade 11. With such a configuration, an attachment mechanism for attaching the first vertical single pipe 5 to the balustrade 11 is constituted by the second horizontal single pipe 9 and the second vertical single pipe 8. Such a second horizontal single tube 9 functions as a connection single tube that connects and fixes the first vertical single tube 5 and the second vertical single tube 8 to each other above the balustrade 11.

  The operation and effect of the fixing structure 1 in the suspension scaffold shown in FIGS. 1 to 3 will be described. As shown in FIGS. 1 to 3, the first vertical single tube 5 is fixed to the first horizontal single tube 4 by a first fixture 6. Therefore, various vertical loads are applied to the first vertical single tube 5 via the first fixture 6. On the other hand, the lower end 5 e of the first vertical single pipe 5 is arranged so as to contact the upper surface of the scaffold plate 2. Thereby, the vertical load applied to the first vertical single pipe 5 described above is received by the surface by the scaffold plate 2. According to such a relationship, the vertical load applied to the suspension scaffold fixing structure 1 can be received by the surface (horizontal plane) formed by the plurality of scaffold plates 2 to disperse the stress, and the stress distribution as in a so-called monocoque structure can be achieved. A structure can be formed. Thereby, since the fixed structure 1 can be stabilized more, a more stable suspension scaffold can be assembled and the safety | security of a suspension scaffold can be improved.

  Furthermore, in the first embodiment, the first vertical single pipe 5 is attached along the outer surface 11 a of the balustrade 11. Thereby, the rolling of the 1st vertical single pipe 5 which supports a suspension scaffold can be suppressed, and a suspension scaffold can be stabilized more. In particular, when a suspended scaffold is supported using a chain or a rope instead of the first vertical single pipe 5, an oblique load may be applied to the chain or the rope, which may be unstable. When the first vertical single tube 5 is used as in the first form, it is received as a vertical load by the first vertical single tube 5. For this reason, the intensity | strength of the fixing structure 1 can be improved and a suspension scaffold can be stabilized more.

  In the first embodiment, the second horizontal single tube 9 and the second vertical single tube 8 are used in combination as an attachment mechanism for attaching the first vertical single tube 5. Thus, by configuring the attachment mechanism of the first vertical single pipe 5 with respect to the balustrade 11 with only a single pipe, a simple structure can be obtained and versatility can be enhanced. Furthermore, since the position along the A direction of the second vertical single pipe 8 with respect to the second horizontal single pipe 9 can be adjusted, the balustrade 11 is sandwiched between the first vertical single pipe 5 and the second vertical single pipe 8. At this time, it can be sandwiched while being more closely attached to the balustrade 11. Thereby, since the 1st vertical single pipe 5 can be attached to the balustrade 11 more firmly, a suspension scaffold can be stabilized more.

  In the first embodiment, the second horizontal single tube 9 is fixed to the third vertical single tube 10. As a result, in addition to the connection between the first vertical single pipe 5 and the scaffolding plate 2, the connection between the second horizontal single pipe 9 and the third vertical single pipe 10 is established. It can be stabilized.

  Next, an example of a method for assembling the fixing structure 1 and the suspension scaffold including the structure will be described with reference to the flowchart of FIG. 5 and the side views of FIGS. 6 (a) to 6 (e). The methods shown in FIGS. 5 and 6 (a) to 6 (e) are merely examples, and the present invention is not limited to these methods.

  The assembling method of the fixed structure 1 and the suspended scaffold including the structure according to the present embodiment is roughly divided into two processes. The process of forming the initial scaffold (steps S1 to S9) and the formation of the extended scaffold The process is divided into steps to be performed (steps S10 to S22).

Thereby, the attachment to the balustrade 11 of the 1st vertical single pipe 5 is completed.

  Next, the third vertical single pipe 10 is installed (step S9). Specifically, the third vertical single tube 10 extending in the vertical direction C is attached and fixed to one end of the L-shaped member 7 provided in step S4. For the fixing, for example, a pin provided inside the L-shaped member 7 can be used to fit the third vertical single tube 10 into the L-shaped member 7. Further, the third vertical single tube 10 is fixed to the second horizontal single tube 9 by an orthogonal clamp.

  By the above-described steps S1 to S9, the initial scaffold by the fixing structure 1 shown in FIGS. 1 to 3 can be formed. When these processes are performed, if the vertical distance from the balustrade 11 to the ground is long, it can be performed from a road surface such as an expressway or a bridge using an aerial work vehicle (bridge checker). On the other hand, when the distance from the balustrade 11 to the ground is short, the work can be performed from the ground without using an aerial work vehicle.
