<p>A scaffolding system comprises two sets of boards 30o to 30s and 30u to 30z laid side by side on transoms 32, 34 etc with their ends aligned. The ends of the boards 30o etc are interconnected by a connector 40 tied to ledgers 36, 38 of the scaffolding by means of cable ties 42 passed through perforations 40e in a dependent flange 40d of the connector 40. The perforations 40e are spaced apart along the flange 40d by an amount equal to the pitch p of the scaffolding. The connector has an upper strip 40a overlying the boards and a lower strip 40b underlying the boards and joined to the upper strip by a web 40c. The web 40c separates the upper and lower strips 40a and 40b by an amount sufficient to receive the boards 30o etc snugly. Preferably the boards and the connector are formed of the same synthetic plastics material.</p> |
