装置が開発されている。2. Description of the Related Art Conventionally, when performing inspection work or repair work such as painting on a truss structure below a floor slab in a bridge structure such as a suspension bridge, a lower chord spans between the upper chord member and the lower chord member of the truss structure. The scaffolding device is constructed by continuously assembling the scaffolding frame vertically and horizontally from the material.With such a scaffolding device, the parts of the truss structure that do not require inspection or painting are completely assembled. Since it has to be done, the assembly work requires a great deal of labor and labor, a large number of scaffolding frames and scaffolding plates are required, resulting in a high construction cost, and disassembling after use also requires a long period of time. is there. Therefore, a scaffolding device as shown in FIG. 7 has been developed.

立費用を一層低減することができる。According to the scaffolding device including the scaffolding unit, as described in claim 3 , a plurality of scaffolding units are provided on the horizontal structural member of the bridge structure at the left and right inner sides thereof at regular intervals in the longitudinal direction. The leg rods are attached along both sides of the horizontal structural member, and the scaffolding units that are adjacent to each other in the longitudinal direction of the horizontal structural member are connected and fixed to each other by handrail members, and the lower ends of the left and right adjacent rod rods are connected. Since the scaffolding plate support rods that connect the two parts support the ends of the scaffolding plate, each scaffolding unit is firmly attached in a fixed posture straddling the horizontal structural members as described above. The adjacent scaffolding units will face each other accurately, and in combination with the scaffolding unit assembly work, handrail member mounting work and scaffolding board erection work can be performed easily and efficiently, further reducing assembly costs. Rukoto can.
