2.Scaffolding must be equipped with longitudinal and transverse base plates. The longitudinal base plate should be fixed to the upright pole no more than 200 mm above the base using right-angle fasteners. The transverse base plate should be fixed with right-angle fasteners to the upright pole immediately below the longitudinal base plate. When the base heights of upright poles differ, the longitudinal base plate on the higher side should extend two spans toward the lower side and be fixed to the upright pole. The height difference should not exceed 1 m, and the distance from the axis of the uphill upright pole to the slope should not be less than 500 mm.
3.Steel pipe uprights should be placed on steel base plates. For soft ground, wooden planks should be used as padding or base plates installed, with the base plate no more than 200 mm above the ground.
4.Scaffolding uprights must be vertical, with a vertical deviation not exceeding 1/200 of the height. The spacing between uprights must not exceed 2 meters.
5.Horizontal bars of scaffolding at passages and ladder points should be arched and reinforced without obstructing passage.
6.The step distance of cantilever scaffolding horizontal bars is generally 1.2 meters, and diagonal bracing should be added. The angle between the diagonal bracing and the vertical plane should not exceed 30°.
7.To prevent frame pipes from bending under pressure and fasteners slipping off pipe ends, the end overlap of intersecting members should be more than 10 cm.
8.If power lines or electrical equipment are present in the scaffolding work area, safe distance requirements must be met. Power outages should be implemented during erection and dismantling.
9.During scaffolding acceptance, all components must be visually inspected, and a tagging system for acceptance and use must be implemented.
10.Before erecting scaffolding, frame pipes, fasteners, bamboo planks, and wire must be inspected. Severely bent frame pipes, heavily corroded or cracked fasteners, and rotten bamboo planks must be discarded and are strictly prohibited from use.
11.It is forbidden to place scaffolding directly on floor joists or non-structural components (e.g., railings, pipes) without calculating additional loads. Scaffolding and planks must not be fixed to unstable structures.
12.Scaffolding planks must be securely connected to the scaffolding. Both ends of the planks should rest on horizontal bars and be fixed. It is strictly prohibited to have joints in the planks between spans.
13.Scaffolding planks and ramp boards should be fully laid on the horizontal bars of the frame. Guardrails 1 meter high should be installed on both sides of ramps, at ramp endpoints, and on the outer sides of scaffolding work surfaces. Additionally, 18 cm high toe boards should be installed at the bottom.
14.Scaffolding must be equipped with secure ladders for workers to ascend and descend and for material transport. When using lifting equipment to hoist heavy objects, it is strictly prohibited to connect the lifting equipment to the scaffolding structure.
15.The scaffolding supervisor must inspect and issue a written certificate before the scaffolding is put into use. The maintenance supervisor should inspect the condition of in-use scaffolding and planks daily, and any defects must be repaired immediately.
16.It is strictly prohibited to use wooden barrels, wooden boxes, bricks, or other building materials to create temporary scaffolding planks as substitutes for proper scaffolding.
17.It is forbidden to install electrical wires on scaffolding. If temporary lighting lines must be installed, wooden or bamboo scaffolding should be equipped with insulators, and steel pipe scaffolding should be fitted with wooden horizontal bars.
18.When installing steel pipe scaffolding, the use of bent, flattened, or cracked pipes is strictly prohibited. All pipe connectors must be intact to prevent the frame from tilting or shifting.
19.Steel pipe scaffolding uprights must be placed vertically and stably on base plates. The ground should be compacted and leveled before placing the base plates. Uprights should be set on column bases (consisting of support bases and short pipes welded to the bases).
20.Joints of steel pipe scaffolding should be connected using dedicated hinges suitable for right, acute, and obtuse angles (e.g., diagonal bracing). Bolts connecting components must be tightened.
21.Scaffolding planks must be fixed to the horizontal beams of steel pipe scaffolding.
22.When moving scaffolding, all workers on the frame must evacuate. It is strictly prohibited to move scaffolding while workers are on it.
