"Safety Construction Specifications for Fastener-type Steel Pipe Scaffolding (Mobile Scaffolding, Portal Scaffolding) in Construction" JG130-2011; "Safety Technical Specifications for Work at Height in Construction" JGJ80-91; "Safety Inspection of Construction Standard" JGJ59-2011; Notice of "Management Regulations on Restricting the Use of Bamboo Scaffolding (Mobile Scaffolding, Portal Scaffolding) in Construction Projects in Guangdong Province", Jianguan Zi (2003) No. 38.
The clear distance between the mobile scaffolding pole and the wall should be greater than 150mm; when it is greater than 150mm, internal overhang boards or other safety measures for exit protection should be taken. Cross supports should be provided on both the inner and outer sides of the mobile scaffolding and locked securely with the lock pins on the scaffolding poles. The operating layer of the scaffolding should be continuously covered with hook-type scaffolding boards matching the scaffolding, and the baffles should be fastened to prevent the scaffolding boards from falling off and loosening. ?
Scaffolding must be reliably connected to the building using wall fittings. At the corners of the scaffolding (straight-shaped, trough-shaped), additional wall-connecting parts should be installed at the C end of the scaffolding, and the vertical spacing should not be greater than 4 meters. When the width of the opening is one span, horizontal reinforcement rods should be installed on the inside and outside above the scaffolding opening, and diagonal braces should be added at the two upper corners of the opening.
Extended information
Scaffolding in use (mobile scaffolding, portal scaffolding) should be inspected regularly and recorded. If any hidden dangers are discovered, rectification and improvement must be notified within a time limit. The main inspection items are:
1. Whether there is water in the foundation, whether the base is loose, and whether the vertical pole is suspended;
2. Whether the overall and local verticality deviation of the scaffold and the settlement of the vertical pole meet the requirements of the specification. , especially pay attention to the verticality of the corners and fractures of the scaffolding (mobile scaffolding, portal scaffolding);
3. Whether the fastener bolts are loose;
4. Footsteps Whether it is loose or overhanging, special interfaces and corner positions;
5. Whether the connections with the building are intact, whether they are loose or moving;
6. Outsourcing safety net, exterior Check whether safety nets, safety isolation facilities, outer baffles, barriers and other safety protection measures are complete and firm, and whether they can function normally;
7. The openings of scaffolding (mobile scaffolding, portal scaffolding), Fractures and entrances and exits should be inspected to see if they meet the requirements of safety regulations;
8. Check the load condition of the scaffold (mobile scaffold, portal scaffold) so that the actual load does not exceed the design load. The scaffold (mobile scaffold, portal scaffold) The construction materials on the portal scaffolding) should be transported as they are used, and the construction load shall not be greater than the load-bearing requirements designed by the construction organization;
9. During the use of the scaffold (mobile scaffolding, portal scaffolding), it is strictly prohibited to dismantle the vertical and horizontal Uneven poles, vertical and horizontal sweeping poles and wall-mounted parts;
10. Regularly check the acceptance status of scaffolding (mobile scaffolding, portal scaffolding) to see if it meets the requirements of the specification, and whether the acceptance workers and employment certificates have been changed. .
