This type of scaffolding is placed at an arbitrary position above a large space, and by using this scaffolding, maintenance and management of ceilings such as lighting is carried out (for example, (Refer to Publication No.-117845).

[Problems to be Solved by the Invention] However, in such conventional scaffolding for large buildings with large spaces, the tip and rear ends of the scaffolding are not connected, that is, the scaffolding is not circular. Since the scaffolding was placed above a large space, there was a problem in that the scaffolding could not be moved freely, which hindered work.

That is, for example, if you are working at the tip of a scaffolding and go from this state to the rear end, if the scaffold is formed in an annular shape, if you continue forward, the rear end will be at a short distance. However, there was a problem in that one had to take a detour around the platform and walk to the rear end.

The present invention was made to solve the above-mentioned problems, and an object of the present invention is to provide a scaffold for a large building having a large space in which the scaffold can be freely moved.

[Means to solve the problem]

The scaffolding for a large building having a large space according to claim 1 is a scaffold for a large building having a large space, which is provided with a scaffolding for working above the large space of the large building. The scaffold is formed by forming the above-mentioned scaffold into a ring shape.

The ladder scaffolding for a large building having a large space according to claim 2 is a scaffold for a large building having a large space, which is constructed by providing a plurality of ladder scaffolds for working above the large space of the large building. In a vertical scaffold, a plurality of vertical scaffolds are connected by crossing scaffolds.

The scaffolding for a large building having a large space according to claim 3 is the scaffolding for a large building having a large space according to claim 1, wherein the scaffolding is formed in an annular shape above the large space. These concentric annular scaffolds are arranged concentrically, and these concentric annular scaffolds are interconnected by scaffolds.

[For production]

In the scaffolding for a large building with a large space as claimed in claim 1, the scaffolding is formed in an annular shape, so that when working near the scaffolding, the circular scaffolding can be used freely. It becomes possible to go back and forth.In the case of the scaffolding of a large building with a large space as described in claim 2, multiple scaffoldings are connected by crossing scaffolds, so that work can be carried out near the connected scaffoldings. In some cases, it is possible to move freely between connected scaffoldings.

In the scaffolding for a large building having a large space according to claim 3, in the scaffolding for a large building having a large space according to claim 1, the scaffolding is formed in an annular shape above the large space. Concentric ring-shaped scaffolds were set up concentrically, and these concentric ring-shaped scaffolds were connected to each other by cross-scaffolds, so when working near the ring-shaped scaffolds, it was easy to walk across the concentric ring-shaped scaffolds. This makes it possible to move freely between each annular scaffold.
