低減しようとするものである。However, when the strength of each support point is insufficient, that is, in the case of a support material having a small load-bearing load, it is necessary to take measures such as structurally reinforcing each support point. There is a great deal of time and money involved in the reinforcement work. Therefore, the present invention provides a load from a scaffold in one section,
By dispersing not only at the support points of the section but also at the support points of other adjacent sections, the load burden on each support point is reduced, the reinforcement work is reduced, the construction period is shortened, and the construction cost is reduced. What you want to do.

ー３等に結束することにより行う。In this case, the support material 1 is the above-mentioned brace material Ad, which is installed in series between the brace materials Ad. The wire attachment pipes 2 are arranged in a pair in a state of being sandwiched before and after each of the brace members Ad serving as the support member 1, and are horizontally assembled by the triple clamps 6. For each pair,
Wire mounting angles 7 are respectively installed on both left and right sides by U bolts 8 (FIGS. 3 and 4). Scaffold wire 3
In each section, two wires on the left and right sides are stretched between the respective wire mounting pipes 2 at a required interval. In this stretching, both ends are connected to the ends of the horizontal pieces of the respective wire mounting angles 7 via turnbuckles 9 and shackles 10 so as to be adjustable in length (FIGS. 3 and 4). The unbalanced force transmitting rod-shaped member 4 uses a straight tie bar 11 such as a reinforcing bar, and stretches two right and left wires along the scaffold wire 3 between the wire mounting pipes 2. For this spanning, both ends are joined to the ends of the vertical pieces of the respective wire mounting angles 7 with bolts and nuts (FIGS. 3 and 4). Further, each tie bar 11 has a sleeve nut 12 interposed at an appropriate position so as to be adjustable in length. The scaffold 5 has a number of arm pipes 13, scaffolding boards 14, free steps 15, handrail pillar pipes 16,
It consists of a handrail pipe 17, other clamps and the like. Then, the assembling of the scaffold 5 by these members is performed by moving the arm pipes 13 at predetermined intervals between the left and right scaffold wires 3 and fastening the respective scaffold wires 3 and the respective arm pipes 13 with the wire fixing clamps 18. On the arm pipe 13, a flat scaffold plate 14 shown in FIG. 1 is laid at a place where the inclination is relatively small, and a free step 15 shown in FIG. 2 is laid at a place where the inclination is relatively large. It is bound and fixed to the arm pipe 13 as appropriate. Further, the lower end of the handrail column pipe 16 is fastened to each wire fixing clamp 18 by erecting, and the handrail pipe 17 is moved to the upper end of each handrail column pipe 16 and fastened by the free clamps 19 respectively. Under the scaffold 5, a safety net 20 is uniformly provided. The safety net 20 is formed by binding both sides to the scaffold wire 3 or the like.

The tie bar 11 as the unbalanced force transmitting rod-shaped member 4 at each location transmits the other part to the adjacent support member 1 one after another via the wire mounting pipe 2 and the like. The other support material 1 which has dispersed and received this bears correspondingly.

展開が期待できる。According to the present invention, since the configuration is as described above,
The following effects are obtained. The number of support points for supporting the load acting on the scaffold can be increased, so that there is no need to reinforce the support points, thereby shortening the construction period and reducing the construction cost. Since it is possible to use lightweight materials, the workability can be improved. Horizontal deployment can also be expected as a hanging scaffold for structures that change three-dimensionally.
