1. Fixing Method of Cantilever Beams
During the binding of floor steel bars, two door-shaped clamps made of 14mm Grade I steel bars shall be pre-embedded. The first clamp is 450mm away from the wall, and the second is 350mm from the outer end. All clamps shall be firmly hooked with floor bottom steel bars to meet anchorage standards.
The I-steel cantilever beam is inserted into the pre-embedded clamp frame and fixed by electric welding, realizing stable and reliable installation of the cantilever foundation structure.
2. Standard Safety Management Requirements
Professional Operator Qualification
Scaffolding erectors must be certified professional workers complying with GB5036 standards. They shall pass regular physical examinations and wear complete protective equipment including safety helmets, safety belts and anti-slip shoes during operation.
3.Quality and Load Control
All scaffolding components and erection works must pass strict acceptance before use. On-site construction load shall comply with design standards, and overloading is strictly prohibited. It is forbidden to fix formwork supports, wind cables, concrete delivery pipes or suspend lifting equipment on the scaffolding frame.
Daily Inspection and Weather Management
Erection and dismantling work shall be suspended in severe weather. Regular daily inspections are required to ensure no water accumulation on the foundation, no loose bases or fasteners, intact wall connections and supports, and qualified verticality of the overall frame.
4.On-site Operation Discipline
Dismantling of main node horizontal bars, sweeping bars and wall connections is prohibited during operation. Excavation around the scaffolding foundation is not allowed without effective safety measures. Special guardians and fire prevention measures are mandatory for electric welding and gas welding operations on the scaffold.
Enclosure fences and warning signs shall be set during erection and dismantling, with special personnel on duty to exclude irrelevant personnel from the construction area.
Conclusion
Standardized beam fixation and standardized safety management are the core guarantees for cantilever scaffolding construction. Strict implementation of operation specifications and protection measures can effectively avoid safety hazards, stabilize project quality and ensure efficient and orderly construction progress.
