Swivel Coupler
A swivel coupler is a crucial formwork and scaffolding accessory used in construction to connect two steel tubes at any angle. View Complete Details...
Product Specification
A swivel coupler, also known as a swivel clamp, is a vital accessory in construction, particularly in formwork and scaffolding systems. It is designed to securely connect two scaffold tubes at any angle, providing flexibility and stability in temporary structures like formwork supports, access scaffolds, or bracing systems.
Key Functions in Formwork Applications
1. Angular Connection
The swivel coupler allows two tubes to be joined at various angles (typically 0°–360°), making it ideal for
• Diagonal bracing in formwork.
• Connecting horizontal and vertical members in non-standard layouts.
• Adjusting to site-specific angles that fixed couplers can’t accommodate.
2. Structural Support
In formwork systems, stability is crucial. Swivel couplers help in
• Providing lateral support to vertical shoring systems.
• Holding ledger and bracing members in position under load.
• Ensuring alignment and rigidity of formwork panels.
3. Ease of Assembly and Disassembly
Swivel couplers are
• Reusable, reducing material waste and cost.
• Manually tightened using a simple wrench, requiring no specialized tools.
• Quick to install, which saves labor time during setup and dismantling.
Technical Specifications (Typical)
| Parameter | Specification |
| Material | Drop forged steel or cast iron |
| Tube Compatibility | Ø48.3 mm (standard scaffold tube) |
| Finish | Galvanized for corrosion resistance |
| Load Capacity | Around 6.25 kN (varies by type) |
| Angle Range | 0° to 360° |
| Compliance Standards | BS EN 74, ASTM A197, etc |
Types of Swivel Couplers
1. Pressed Steel Swivel Coupler
Lightweight, used for lighter applications.
2. Forged Swivel Coupler
Heavier-duty, suitable for high-load or high-stress environments.
3. Right Angle vs. Swivel
While right-angle couplers fix tubes at 90°, swivel couplers allow free angular adjustment, making them more versatile.
Applications Beyond Formwork
• Scaffold bracing and ties.
• Temporary fencing.
• Supporting access platforms or ramps.
• Connecting tubes in custom structural assemblies.
Safety and Quality Considerations
• Always check for compliance with safety standards.
• Inspect for cracks, corrosion, or thread wear before reuse.
• Ensure tightness of bolts to prevent slippage under load.
Swivel couplers are an indispensable part of formwork accessory systems in construction. Their flexibility, strength, and ease of use make them ideal for a wide range of structural applications. By enabling secure, angled connections between scaffold tubes, they help maintain safety, efficiency, and structural integrity on-site.
