険作業を伴う等の欠点がある。In the above-mentioned conventional scaffolding temporary construction, an operator having a special skill called a eagle worker sequentially assembles scaffold logs or scaffold pipes and scaffold plates,
It is expensive and requires a considerable amount of work. Also, when a worker moves on the scaffolding board, it is dangerous to get caught in the scaffolding log binding line. Further, when working in the middle stage, there is a scaffolding above the head, and there is a risk of hitting the head. Furthermore, as shown in FIG. 5, a temporary scaffold 33 for non-destructive inspection of the circumferential welding line 32 inside the spherical holder 31.
Has a drawback in that the scaffolding material has to be loaded into the interior from the upper manhole 34 by a wrecker and assembled, and therefore dangerous work such as dropping is involved.
