A coupler 10 for connecting a conventional scaffold tube 40 to a scaffolding component of a proprietary scaffolding system 12 comprises a body portion having a proximal end adapted to engage with the scaffolding component, and a distal end adapted to engage with the scaffold tube. A mechanism, for example threaded fasteners 38, 39, is provided to releasably secure the scaffold tube to the distal end of the coupler. The proprietary systems may include Ringlock, Allround , Kwikstage or Cuplock. The proximal end of the body portion may be V- or U-shaped, defining an opening that may be closed off by a captive gravity pin 18. A spigot or spindle may be provided on the distal end, allowing the tube to be connected to the scaffolding component at an angle. Also claimed is a scaffolding structure comprising vertical proprietary scaffold standards, ledgers of conventional 48.3mm tube and couplers. |
