1. Ringlock Scaffolding (Cuplock System)

Definition:

Ringlock Scaffolding is a modular, cup-lock scaffold system. Vertical steel standards feature fixed welded cups (nodes) at regular intervals (typically 500mm). Horizontal ledgers and diagonal braces are inserted into these cups and secured with locking heads, forming a rigid, grid-like structural framework.

Key Components:

• Standards: Primary vertical load-bearing columns with integral cups.

• Ledgers & Braces: Horizontal and diagonal members inserted into cups and locked.

• Adjustable Bases & Platforms: Components for leveling and providing working surfaces.

Comparison with Kwikstage:

Ringlock Scaffolding features an 8-hole cup design accommodating braces, while Kwikstage uses a 4-hole cup without dedicated brace points. Ringlock utilizes higher-grade Q345B steel with hot-dip galvanizing versus Kwikstage’s Q235 steel with painted finish. Ringlock offers superior strength (≥200kN capacity) and is suited for high formwork, bridges, and subways. Kwikstage is primarily used for low-level indoor formwork. Ringlock’s enhanced strength, stability, and durability make it the mainstream system for demanding applications.

Advantages:

Structural Safety & Stability: The cup-lock connection creates a load-bearing structure with exceptional concentrated load capacity and lateral force resistance.

Standards & Safety Recommendations:

• Compliance with national/international codes (e.g., Chinese Standard JGJ/T 231-2021) is mandatory.

• Requires pre-construction planning, ground inspection, trained personnel, and regular inspections.

• Avoid component impact damage, ensure correct brace installation, and suspend operations during high winds.

2. Pipe-Scaffolding (Tube and Coupler Scaffolding)

Definition:

Pipe-Scaffolding connects steel tubes using couplers (right-angle, swivel, sleeve), offering maximum flexibility for irregular structures and complex sites.

Key Components:

• Couplers: Include right-angle types for perpendicular connections, swivel types for diagonal bracing, and sleeve types for tube extensions.

• Tubes: Standards (vertical load-bearing members), ledgers/transoms (horizontal platform members), and braces (diagonal stabilizers).

• Accessories: Base plates, sole boards, guardrails, and platforms.

• Types: Single/double pole, full-span, mobile, and suspended variants.

Advantages:

• Unmatched adaptability to complex/irregular structures.

• Excellent load-bearing capacity for heavy-duty operations.

Limitations:

• Labor-intensive erection/dismantling requiring skilled workers.

• Numerous components increase management complexity and potential costs.

Safety & Standards:

• Essential elements: Sole boards, base plates, tie-ins, bracing, and sleeve couplers for extensions.

• Mandatory pre-use inspection of all components per standards (e.g., JGJ 130-2011, OSHA 1926.452).

• Prevent overloading, ensure coupler tightness, conduct regular inspections, and train operators.

3. Frame Scaffolding

Definition:

Frame Scaffolding uses prefabricated welded portal frames to create stable, modular structures, widely applied in construction, renovation, and bridge work.

Key Components:

• Frames: Welded vertical-horizontal portal units.

• Cross Braces: Diagonal members providing lateral stability.

• Runners: Horizontal members connecting frames transversely.

• Platforms: Work surfaces supported by runners/frames.

Advantages:

• Structural Stability: Geometrically stable with strong lateral resistance.

• High Load Capacity: Suitable for concrete placement and heavy equipment.

• Rapid Deployment: Standardized components enable simple assembly without specialized tools.

• Safety: Robust connections and easy guardrail integration.

• Cost-Effectiveness: Durable steel enables long-term reuse.

Limitations:

• Requires larger ground space, impacting site efficiency.

• Heavy components increase manpower requirements.

• Limited adaptability to highly complex geometries.

Applications:

• Building construction (multi-story walls, masonry).

• Bridge construction (deck/pier support).

• Renovation (finishing, ceilings).

• Heavy equipment installation.

Standards:

• Compliance with relevant codes required (e.g., JGJ 76-2017).

Overall Summary

• Ringlock Scaffolding: Optimal for high-strength/stability applications (bridges, high formwork). Requires strict procedural adherence.

• Pipe-Scaffolding: Maximizes flexibility for irregular structures with heavy loads. Demands skilled labor and meticulous management.

• Frame Scaffolding: Delivers rapid deployment for standard layouts with cost-effective repetition.

Less effective in constrained/complex sites.

System selection must align with project type, structural requirements, site conditions, safety regulations, and budget.
