<p>PROBLEM TO BE SOLVED: To prevent the electric shock of a worker and the destruction of equipment due to overcurrent by making a plurality of posts and inter-post distance maintaining members for keeping the posts at a specified distance, by means of an insulating resin. SOLUTION: A built-up type scaffolding is constituted of built-up type scaffolding units made by allowing a pair of frames, each constituted of a post 1 and an inter-post distance maintaining member 2 connected to the post 1, so as to face each other and keeping them at a specified distance by means of the inter-post distance maintaining members 2, such as diagonal braces and horizontal members. In the built-up type scaffolding, at least two built-up type scaffolding units are plied up and connected to each other, and the lowest unit is provided with a bottom wheel 9 and a jack base 8. At this time, each of the posts 1 and each of the inter-post distance maintaining members 2 are made of an insulating resin, which is fiber-reinforced resin, such as inorganic glass fiber and alumina fiber. By this method, electric shocks or the like caused through making contact with the materials of the scaffolding can be prevented.</p> |
