せるものがあった。As a gondola device used in the conventional construction, for example, four box-type deck type gondola devices are prepared, and each gondola device is erected on a steel tower via two suspension wires, and each gondola device is provided. In some cases, a gondola device is moved up and down along a steel tower by winding a suspension wire by a winding winder device installed and fixed to the device.

【発明が解決しようとする課題】しかしながら、従来の
櫓状の足場を施工する工法においては、円柱鉄塔が、例

箇所も必然的に多くなっていた。However, in the conventional method of constructing a tower-like scaffold, in the case of a column tower, for example, a power transmission tower, the tower itself is often built on a narrow site, so that it is narrow. Construction of scaffolds on the site is very difficult. Also, on narrow roads, transporting the scaffolding material is very difficult. In addition, the construction and dismantling of the scaffold required a considerable number of days, and construction costs were likely to be high. In addition, since there are many locations where the scaffold members are combined, the assembly is extremely complicated and troublesome, and the number of locations requiring a safety check is inevitably increased.

た。On the other hand, when four box deck type gondola devices are prepared and installed and used, since the hoisting winder devices are fixed to each gondola device itself, the hanging points coincide with the hoisting winder devices. The disadvantage is that only a column-sized steel tower can be installed. Moreover, since a total of eight suspension wires are used, a large force of about 1232 kg acts on the column tower. Further, since four gondola devices are used, each gondola device requires an operator for operation, and it is necessary to secure at least four operators. In addition, there are many unloading members at the upper part of the column tower, and there is a problem that considerable time is required for erection and disassembly of the gondola device.

ある。Accordingly, the present invention has been made in view of the above-mentioned problems that have been encountered in the past, and is easy to transport on narrow roads, assemble and disassemble on narrow premises, and reduce the number of hanging wire members of a gondola. The present invention provides a circular gondola device that can minimize the load on the column tower itself and use a tiltable winding winder device to easily install a gondola on a column tower of any diameter. Also,
A single gondola operator is sufficient, the cost is lower than the conventional method of constructing a scaffold, the number of assembly members is reduced, the number of places requiring safety inspections can be reduced, and the conventional scaffold can be constructed. It is an object of the present invention to provide a circular gondola device for column tower construction, which is extremely easy to install and dismantle as compared with the construction method, and requires less work days.

Ｐに与える負担を軽減できる。Next, the load relationship of the gondola body 1 on the corner contact portion L of the intermediate stage Q will be described with reference to FIG. First, assuming that the height between the base wire 5 and the intermediate stage Q is H = 1600 mm, the included angle of the hanging wire 2 about the corner contact portion L is θ = 147 degrees. Then, the load applied to one of the suspension wires 2 of the gondola body 1 is WG = {500 kg of own weight + 350 kg of loading load +
Assuming that the lifting and lowering inertia force is 140 kg 養 / 3 = 330 kg and the weight of the curing net and others is WN = 20 kg per one of the hanging wires 2, the resultant force acting on the beam of the intermediate stage Q by the hanging wires 2 is P = 2 × (WG + WN) × COS (θ / 2)
= 2 × (330 + 20) × COS (147/2) = 19
9kg, horizontal component of resultant force is Ph = P × SIN (θ / 2)
= 199 × SIN (147/2) = 191 kg, and the vertical component of the resultant force is Pv = P × COS (θ / 2) = 199 × CO
S (147/2) = 57 kg. As described above, according to the present invention, the load on the gondola main body 1 applied to the column tower P can be reduced to about half or less of the related art, and the load on the column tower P can be reduced.
