1. The load of the scaffolding shall not exceed 270kg/m2. It can only be used after acceptance and approval. It should be inspected and maintained frequently during use. Scaffolding with a load exceeding 270kg/m2 or special forms should be designed.
2. The scaffolding must be equipped with longitudinal and transverse sweeping rods. The longitudinal sweeping rod should be fixed to the vertical rod at a distance of no more than 200mm from the top of the base with a right-angle fastener. The transverse sweeping rod should also be fixed to the vertical rod just below the longitudinal sweeping rod with a right-angle fastener. When the production pole foundation is not at the same height, the longitudinal sweeping rod at the high position must be extended to the low position by two spans and fixed to the vertical rod, and the height difference should not be greater than 1m. The distance from the vertical rod axis above the slope to the slope should not be less than 500mm.
3. The steel pipe column should be equipped with a steel base. For soft geological foundations, wooden boards should be padded, or sweeping rods should be installed. The sweeping rod should not be more than 200mm from the ground.
4. The scaffolding poles should be vertical, the vertical deflection should not exceed 1/200 of the height, and the distance between the poles should not exceed 2 meters.
5. The scaffolding poles should be vertical, the vertical deflection should not exceed 1/200 of the height, and the distance between the poles should not exceed 2 meters.
6. The scaffolding poles should be vertical, the vertical deflection should not exceed 1/200 of the height, and the distance between the poles should not exceed 2 meters.
7. The crossbars of the scaffolding should be raised and reinforced at the passages and escalators, and should not block the passages.
8. The crossbar step of the cantilever scaffolding is generally 1.2 meters, and diagonal braces should be added. The angle between the diagonal braces and the vertical plane should not exceed 30°.
9. To prevent the frame tube from bending under pressure and the fasteners from sliding off the tube head, the intersecting ends of each rod should be greater than 10 cm.
10. If there are power lines or electrical equipment at the scaffolding site, the safety distance regulations must be met, and power outage measures should be taken during erection and dismantling.
11. During the acceptance of scaffolding, all parts shall be visually inspected, and the acceptance and use system of hanging signs shall be implemented.
12. Before the scaffolding is erected, the frame tubes, fasteners, bamboo rafts, and iron wires must be inspected. Severely bent frame tubes, severely corroded and cracked fasteners, and rotten bamboo rafts must be scrapped and not used.
13. It is prohibited to directly place the scaffolding on the wooden slats of the floor and the structural parts without calculating the additional load or to fix the scaffolding and scaffolding boards on structures that are not very strong (such as railings, pipes, etc.).
14. The scaffolding boards and scaffoldings should be firmly connected. Both ends of the scaffolding boards should be placed on the crossbars and fixed firmly. The scaffolding boards are not allowed to have joints between spans.
15. The scaffolding boards and ramp boards should be fully spread on the crossbars of the frame. On both sides of the ramp, at the end of the ramp, and on the outside of the scaffolding work surface, a 1m high railing should be installed, and an 18cm high guard plate should be added at the bottom.
16. The scaffolding should be equipped with a solid ladder to facilitate workers to go up and down and transport materials. When lifting heavy objects with a lifting device, it is not allowed to connect the lifting device to the scaffolding structure.
17. The leader of the scaffolding work should inspect the scaffolding and issue a written certificate before it is allowed to be used. The person in charge of maintenance work should check the condition of the scaffolding and scaffolding boards used every day. If there are defects, they must be repaired immediately.
18. It is strictly forbidden to use wooden barrels, wooden boxes, bricks, and other building materials to build temporary planks instead of regular scaffolding.
19. It is forbidden to pull wires on the scaffolding. When temporary lighting lines must be installed, wooden and bamboo scaffolding should be equipped with insulators, and steel pipe scaffolding should be equipped with wooden crossbars.
20. When installing steel pipe scaffolding, it is forbidden to use bent, flattened, or cracked pipes. The connecting parts of each pipe must be intact to prevent tipping or movement.
21. The vertical poles of the steel pipe scaffolding must be placed vertically and stably on the pad. The ground must be compacted and leveled before placing the pad. The vertical poles should be covered with column bases, which are made of support bases and pipes welded to the bases.
22. The joints of the steel pipe scaffolding should be overlapped with each other using special hinges. This hinge is suitable for right angles, acute angles, and obtuse angles (for diagonal braces, etc.). The hinge bolts connecting the various components must be tightened.
23. The scaffolding board must be fixed on the crossbeam of the steel pipe scaffolding.
24. When moving the scaffolding, all workers on the scaffolding must get off, and the scaffolding with people working on it is prohibited from moving.
