I. Core Construction Process
The erection follows the logic of from bottom to top, main components first, gradual stabilization.
1. Accurate Positioning and Stable Foundation
Set out lines according to the approved special construction scheme to determine the position of vertical poles.
The foundation shall be compact and level with sufficient bearing capacity. The adjustable base shall be well lubricated with about 250mm reserved adjustment height for leveling.
2. Main Scaffold Erection
Install vertical poles into the base vertically to ensure verticality.
Connect horizontal poles by inserting wedge plugs into the rosette nodes and tightening locking pins firmly to form rigid joints.
Install the bottom horizontal ledger to restrict displacement of pole bases.
3. Structural Bracing and Reinforcement
Install diagonal braces to provide lateral stiffness and resist horizontal loads in lattice, V-shaped or X-shaped layouts as required by JGJ/T 231.
Anchor the scaffold to stable building structures with reliable wall ties to prevent overturning, especially for high-rise structures.
4. Tiered Erection and Top Support
Erect layer by layer in the order of vertical poles → horizontal poles → diagonal braces.
Control adjustable jacks strictly:
Cantilever length ≤ 500mm
Exposed screw ≤ 400mm
Insertion depth ≥ 200mm
II. Key Control Points
1. Dimensional Accuracy
Horizontal deviation: ≤5mm between adjacent ledgers; overall ≤ L/500 and ≤50mm.
Verticality deviation: ≤5mm per lift; overall ≤ H/1000 and ≤50mm.
Position deviation of vertical poles ≤10mm.
2. Adjustable Component Limits
Exposed screw of adjustable base ≤300mm.
Height of bottom ledger ≤550mm.
Strict limits for adjustable jacks as specified above.
3. Mandatory Bracing and Wall Ties
Diagonal braces and wall ties must be fully installed as designed. Loose or missing parts will severely reduce stability.
III. Materials, Acceptance and Safety Management
1. Material Quality Control
All components must have factory certificates. Check for cracks, corrosion, deformation and thread damage. Cracked, rusted or substandard parts are strictly prohibited.
2. Inspection and Acceptance
Erection shall be conducted by certified scaffolders with full supervision.
Formal acceptance is required before use in accordance with JGJ/T 231, JGJ 162 and approved construction scheme.
Overload is prohibited. Special projects may require preloading tests.
3. Safe Use and Dismantling
Dismantle in the order of from top to bottom, last installed first removed.
Wall ties shall be dismantled layer by layer and shall not be removed in advance.
IV. Industry Pain Points and Development Trends
Substandard materials, inconsistent schemes and loose joints are major hidden dangers.
Development directions include BIM application, IoT intelligent monitoring, new locking technologies and improved standard systems.
Conclusion
The safety of ringlock scaffolding relies on qualified materials, standardized design, strict construction and management. Adhering to dimensional control, full bracing and effective wall ties ensures a safe and reliable construction system.
