1. When using the bamboo raft (other materials) scaffold, the end of the small crossbar of the single-row scaffold is fixed on the pole (large crossbar) with the right angle fastener, and the other end is inserted into the wall, and the insertion length should not be less than 180mm.
2. The work layer scaffolding should be covered and stabilized. The scaffolding board is butted and tiled. There must be two small crossbars at the joint. The outer extension of the scaffold should be 130~150mm. The sum of the outer extensions of the two scaffolds should not exceed 300mm. Except for the bamboo slab scaffolding board, the scaffolding board can be laid up and laid. The joints to be laid must be supported on the small crossbar. The lap length should be greater than 200mm, and the length of the protruding small crossbar should not be less than 100mm.
3. The length of the probe at the end of the working layer should be 150mm, and both ends of the plate should be reliably fixed with the support rod.
