2. Operators must pass the training and examination and hold relevant certificates, wear safety helmet and work shoes, and fasten their seat belts when working at heights.

3. Erect or dismantle in strict accordance with the requirements of the product manual and the erection and dismantling operation plan.

4. Before operation, check whether the foundation is compacted and smooth, whether the frame body and components are complete, and those with serious desoldering, cracks, deformation and corrosion are not allowed to be used. Incompatible portal frames and accessories are not allowed to be used in the same scaffold. Whether the safe distance between the job site and the high-voltage line is sufficient, whether the alert has been set within 1m below the job scope, whether pedestrians are prohibited from passing or standing, and whether there are eye-catching safety signs.

5. Erection sequence: foundation-steel pad, base-gantry sweeping rod-diagonal brace-parallel frame-scaffold board-connecting pipe-previous gantry-arm buckle (erected layer by layer)-and beam edge on the second floor (Rachel layer by layer, horizontal spacing shall not be more than 7m), without parallel frame.

6. The inside of the frame is not more than 2cm away from the wall. If it is more than 2cm, a horizontal safety net between the inside of the frame and the wall should be set every other floor, and a safety net should be hung on the outside of the frame.

7. Each erection must be 1.2m higher than the structural construction working surface, and acceptance shall be conducted by sections.

8. The vertical deviation of the frame body is not more than 1/1 of the total height, and the absolute value is not more than 1mm.

9. An unloading measure should be added to the scaffold outside the high-rise building every five stories. When there is negative wind pressure in windy areas or typhoons or when the height exceeds 1m, anti-pulling measures should be added.

1. When hanging and erecting external scaffolding, the bottom bracket should be made of I-shaped steel frame, welded into a triangle, and the top pulling member should be welded firmly and reliably with the embedded parts of the building structure. When necessary, reinforcement measures should be taken for the building structure.

11. At the corner of the scaffold and at both ends of the unclosed scaffold, even wall pieces should be added, and the vertical spacing should not be greater than 4m.

12. The safe distance between scaffolding and overhead transmission lines, erection of temporary power lines on site and lightning protection measures for scaffolding grounding shall be implemented according to the relevant provisions of the current industry standard "Technical Specification for Safety of Temporary Power Use on Construction Site".

13. A large steel tube brace (cross cover) should be set on the outer side of the scaffold every six columns, and the included angle with the ground should be not less than 45 and not more than 65, and the bolts should be connected with the frame body by rotating buckles. Rachel is not allowed on the main bar.

14. When two people pass the portal frame or bar, the upper personnel shall not let go until they are firmly connected. It is not allowed to touch, touch or press power wires and electrical equipment.

15, scaffolding are not allowed to overload stacking components and materials.

16. On the operating floor of the scaffold, the hanging scaffold board matching with the portal frame should be spread all over, and the baffle should be fastened to prevent the scaffold board from falling off and loosening.

17. When using tower cranes to lift scaffolding, braces and other components, they should be firmly bound, and short materials such as wall rods and bolts should be packed in steel wire sealed baskets for lifting, and they should not be too full. The site should be on the concrete floor. Each lifting weight is not more than 3N n. And tied up and discharged by the licensed contractor.

18, scaffolding, head of the unit engineering inspection to verify and confirm that it is no longer needed, can be removed.

19. Before dismantling, check and clean up the sundries on the scaffold board, check whether there are wires on the frame body, and dismantle it layer by layer from top to bottom (including the wall pole), and check whether the warning range sign below the operation has been implemented.

2. During the dismantling operation, it should be carried out under the unified command in the order of assembling first and disassembling first, and it is strictly forbidden to dismantle the connection of the wall pole or all the continuous three-layer frames first.

21. During the dismantling operation, the portal frame and components shall be removed one by one and transported to the floor, transported back to the ground, and sorted and stacked neatly.

22, clean the mortar on the portal frame and components, paint maintenance.
