1) Pole Hole:

The holes are 300-500mm deep, with a diameter 100mm larger than the pole diameter. The bottom diameter of the holes is slightly larger than the mouth diameter, allowing for more backfill soil. This design minimizes natural soil disturbance at the mouth, making it easier to tightly fit the poles and securely bury them.

2) Sweep Rod:

When the scaffolding height is low and the foundation is made of hard soil layers like rock, it is not necessary to dig a pile hole. Instead, the posts can be directly set up on the ground, with a sweeping rod tied at the bottom of the post.

3) Piling Rod

First, set up the upright poles at both ends, then the central upright pole, and proceed with the outer row poles in sequence according to the inner row poles. Once the poles are upright, they should form rows vertically and squares horizontally, with the pole shafts perpendicular. If a pole bends, the bend should be in the longitudinal direction, neither facing the wall nor away from it, to ensure good contact between the large crossbar and the upright poles.

4) Tie down crossbar

The ends of the large horizontal bars on the scaffolding should face outward. When binding the large horizontal bars, check if the vertical posts are properly and securely buried. The direction of the large horizontal bars on the same step should be consistent, and the direction of the large horizontal bars on adjacent steps should be opposite to enhance the overall stability of the scaffolding.

5) Strapping crossbar

The small cross-bar is tied to the vertical rod. Pre-fabricated scaffolding boards made of bamboo, wood, or steel mesh should have the small cross-bar positioned below the large cross-bar; for boards supported longitudinally, the small cross-bar should be placed above the large cross-bar.

6) Tie-down bracing:

The top support is positioned upright next to the pole, tied to the pole in three places, and presses against the tightly secured crossbar. When the crossbar of the scaffold is below the main bar, a top support must be installed. The top support should be made of a single bamboo pole and should not be extended. The upper and lower top supports should be aligned in a straight line. The lower end of the bottom support should rest on a solidly packed block of material, such as bricks or wood, on the ground. The lower ends of the supports on other levels should not be supported by any blocks.

7) Laying Scaffold Boards:

Deck boards are tied to joists horizontally, while straight-laid deck boards are tied to cross bars. The operating level deck boards must be fully laid, and the overlap of straight-laid deck boards should be at the cross bars.

8) Tie-backs, diagonal bracing, and scissor bracing:

When scaffolding is erected to a height of three steps or more, it should be tied with diagonal bracing (for scaffolds 15m or less in length) and diagonal剪刀撑 (for scaffolds over 15m in length).

9) Establishing Wall Connections:

When the scaffolding height exceeds 7 meters, set up wall connections as the scaffolding is erected. The overall inclination of the scaffolding is 1% inward, and the full height inclination of the scaffolding must not exceed 150mm. It is strictly prohibited to incline outward.

10) Erecting Safety Nets

In compliance with the safety netting and technical briefing requirements for construction site safety.
