Independent scaffolds follow the same principal as putlog scaffolds but are 'free standing', putlogs are replaced with 5ft tubes and a row of standards and ledgers are erected on the inside as well as the outside to provide support, in addition diagonal braces are fitted between standards to give stability.
A putlog scaffold is physically tied into the brickwork using putlogs or tubes with putlog adapters, a slot is left between bricks to accommodate them and once in place the wall itself becomes the inside support. The outside support is formed by a series of standards (upright tubes) and ledgers (horizontal tubes) which are connected using double couplers, the putlogs then sit directly onto the ledgers and are secured using single (putlog) couplers. Once all the putlogs are in place boards are laid across them to form the working platform and a further 2 rows of tube are fitted horizontally to form a guardrail (safety barrier).
