As shown in FIG. 10, since the next vertical member E must be flown between the chains B on the first vertical member E suspended, the operation is difficult unless a skilled person. It takes time and effort. Also, no matter how skilled a stealthy craftsman is, the risk of falling is high, and there are many problems in work safety. b. As shown in FIG. 11, the cross member F must be passed over the vertical member E and fixed, the scaffold plate J must be fixed as shown in FIG. 12, and the fall prevention net N must be stretched as shown in FIG. However, such work is cumbersome, takes a lot of time and effort to complete, and the cost increases accordingly, and the entire construction period is prolonged due to the temporary installation of the hanging scaffold. c. Since the crane C must be moved as shown in FIG. 9, it is very troublesome and time-consuming. In addition, for example, in the construction of a highway bridge, it is necessary to block the road under the bridge in order to move the crane C, which hinders traffic and causes traffic congestion. In addition, when there is a river or pond under the bridge, crane cannot be used,
In such a case, all the operations are performed manually, so that the workability is significantly reduced and the danger is increased. Conventionally, various members such as a single pipe, a scaffold plate J, a track, and a fall prevention net N required for assembling a suspended scaffold are individually and independently separated, so that assembly work on site is troublesome.
