The acceptance standards for disc-lock scaffolding mainly include the following aspects:
1. Components and reinforcements. It is necessary to check whether the components and reinforcements are complete, whether their quality meets the standards, and whether the connections and hooks are tight and reliable.
2. Safety nets and handrails. Confirm that the safety nets are properly installed and the handrails are in place.
3. Foundation flatness and firmness. Check whether the foundation is flat and firm, and whether the supports meet the regulations.
4. Verticality and horizontality. Check whether the verticality and horizontality meet the qualified standards. For socket-type disc-lock steel pipe scaffolding, it should comply with JGJ231 “Safety Technical Specification for Steel Pipe Supports in Building Construction”.
5. Construction plan and scaffold foundation. This includes the construction plan, scaffold foundation, scaffold stability, scaffold installation, footboard installation, commissioning, and acceptance.
6. Safety. Check whether adjustable bases are installed at the bottom of the scaffold uprights, whether the tie points of the scaffold body are firm and reliable, and whether the two ends of the vertical diagonal braces are fixed to the longitudinal beams.
7. Appearance and Workmanship: The inner and outer surfaces of the uprights, horizontal bars, diagonal bars, and components should be hot-dip galvanized. The surfaces should be smooth, and there should be no burrs at the joints.
8. Dimensional Deviations: All relevant dimensional deviations should comply with the specifications in JGT 503-2016, “Socket-Type Disc-Type Steel Pipe Scaffolding Components.”
9. Connecting Disc Strength Tests: This includes single-sided shear strength, double-sided shear strength, bending strength, and tensile strength tests to ensure that all components of the specimen do not fail during the tests.
Furthermore, specific safety regulations must be followed when working at heights. For example, scaffolding erection and dismantling should be stopped in inclement weather, and a safe distance should be maintained between the scaffolding and overhead power lines.
