Ringlock Base Collar

The Base Collar, also known as the starter, is the first component installed in the Ringlock scaffolding system. It is positioned directly on top of a fixed or adjustable base jack, serving as the connection point for the first vertical standard.

Overview


The Ringlock Base Collar is a foundational component designed to secure the base of Ringlock standards, providing stability and alignment for the entire scaffolding structure. Manufactured from heavy-duty galvanized steel, this collar features a cylindrical design with an internal diameter matching the standard’s outer diameter (typically 48.3mm), ensuring a snug fit. It includes a welded base plate with pre-drilled anchor holes, allowing for secure fixing to concrete, steel, or wooden foundations. The collar also has a built-in levelling nut mechanism, enabling minor height adjustments (±50mm) to compensate for uneven ground. Its robust construction can withstand vertical loads up to 15,000kg, making it suitable for heavy-duty applications.


Features


Precision Alignment: The tight-fitting cylindrical design ensures Ringlock standards are vertically plumb, minimizing lateral movement and enhancing overall structural stability.

Levelling Capability: The integrated levelling nut allows scaffolders to adjust standard height on-site, eliminating the need for shims or custom foundations on uneven terrain.

Multi-Mounting Options: The base plate accommodates both mechanical anchors and concrete embedments, making it versatile for different ground conditions, from solid concrete to soft soil with appropriate reinforcement.

Corrosion Resistance: The hot-dip galvanized finish protects the collar from rust and soil moisture, ensuring long-term reliability in buried or exposed installations.


Application


The Ringlock Base Collar is essential for any Ringlock scaffolding project requiring a stable foundation. It is widely used in building construction, where standards must be anchored to basement floors, rooftop slabs, or ground-level concrete pads. In infrastructure projects, such as tunnel portals or bridge abutments, the collar ensures standards are securely fixed to irregular foundations. It is also critical in industrial scaffolding for tall structures, like chimneys or reactors, where precise alignment and load-bearing capacity are non-negotiable. The levelling feature is particularly useful in outdoor events or temporary structures set up on grass or gravel, where ground unevenness is common.


FAQ


Q: Can the base collar be used without a base plate?

A: No, the base plate is integral to distributing loads and anchoring the standard. Always use it with appropriate fasteners for your foundation type.

Q: How much weight can the levelling nut support?

A: The levelling nut is designed for minor adjustments and should not bear the full load. Ensure the base plate is securely anchored before relying on the nut for stability.

Q: Is it compatible with non-Ringlock standards?

A: No, it is designed specifically for Ringlock standards with a 48.3mm outer diameter. Using it with other standards may result in a loose fit and safety hazards.

Q: How deep should the base collar be embedded in soil?

A: For soil foundations, embed the collar at least 300mm deep and use a concrete footer for additional stability. Consult local building codes for specific requirements.
