4. Fasteners with serious corrosion, deformation, cracks and bolt thread damage are not allowed to be used.

5, scaffolding foundation in addition to the set by the regulation, drainage treatment must be done.

6. When the high-rise steel pipe scaffold stands on the channel steel, it must be connected and protected by a sweeping rod, and the common scaffold pole must be protected by a base.

7. Socket-type steel pipes should not be used for the vertical rods staggered at the bottom.

8. The tightening torque of all fasteners should reach 45-55 N.m.

9, the same facade putlog, should be staggered, at the same time, the vertical rod straight up and down.

10, diagonal extension, butt fastener is not suitable. Lapping shall be adopted, and the spacing between two fasteners extending from two rotating fasteners shall be not less than 0.4m.

1 1. Lead wire climbing frame is not suitable for the pull rod of metal scaffolding in high-rise buildings, and rigid materials in the form of embedded parts must be used.

12. A warning zone must be set up at the demolition site, and eye-catching warning signs should be hung. Non-operators are prohibited from passing through the warning zone or continuing construction under scaffolding. Ground monitoring personnel must perform their duties.

19. Demolition shall be carried out according to the reverse procedure of erection, that is, safety net → vertical retaining basketry → cushion laying basketry → protective railing → joist → diagonal tie rod → even wall pole → main rail → small rail → vertical pole.

20, are not allowed to separate surface demolition or two steps up and down at the same time (step). Do a good job step by step, one stroke at a time.

2 1, all wall parts, diagonal tie rods, row separation measures and climbing measures must be lowered synchronously with the removal of scaffold steps. It is not allowed to open it first.

22. When all bars and fasteners are dismantled, they should be carried out separately. Fasteners are not allowed to be attached to the bar conveying ground, or two bars are dismantled at the same time.

23, all mat shop basketry dismantled, should be erected from outside to inside, handling, prevent from inside to outside after turning up, basketry surface garbage objects directly fall from a height.

24, scaffolding must use welding gas cutting process, should be carried out in strict accordance with the requirements of the national special type of work and fire laws and regulations. Full-time staff, equipped with hopper (barrel), to prevent sparks and chips from splashing down. It is forbidden to use cutting tools without a license.

25, after the completion of the day, should carefully check the situation around the post, if found hidden parts, should be timely repair or continue to complete to the end of a program, a part, can leave the post.
