ERECTION PROCEDURE
Before commencing the erection of any couplock scaffold, care should be taken to see that the ground is
suitable. On soft or made up ground, the scaffold should be erected on timber sole planks. Bricks and Blocks should not be used. Always commence erection at the highest point of ground, this will make leveling easier as the scaffolding progresses horizontally.
Layout ledgers and verticals for the first bay in approximate positions. Then insert an adjustable jack into each pair of standards as in Fig.
Connect the standards with the ledger in the lowest cup joint, by inserting the blades into the cups. Level the verticals as in Fig.
With one man still holding the first pair of standards the second men inserts a jack into the third standard and connects it to the first pair with a ledger. The upper cups can be dropped temporarily into the locking position. The structure is self supporting and the fourth standard can now be connected by a further ledger and the bay leveled as in Fig.
The first bay of couplock is completed by locating the upper ledgers. It is now a simple matter to extend the scaffold structure by connecting ledgers. |
