In this type of scaffolding, a working platform is suspended from the roof by means of ropes, wires or chairs. This type of scaffolding is also called an independent scaffolding and is mainly preferred in stone masonry construction, in which it is not possible to leave holes in the wall to receive one end of the putlogs. The first row is at a distance of 200 - 300 mm from the wall and the second is at a distance of 1 m from the first row. It is also known as mason's scaffolding and consists of two rows of scaffolding. The vertical spacing of ledgers is about 1.2 - 1.5 m and spacing of putlogs is 1.2 - 1.5 m. Single scaffolding consists of only one row of standards spaced at a distance of about 1.2 m from the wall and in between them is about 2.0 - 2.4 m. It is also known as bricklayer’s scaffolding and used in brickwork.
The following are the different types of scaffolding: Single Scaffolding: Guard rail: It is a railing provided at the height of 0.8 - 1.0 m from working platform.īase plate or sole plate: These are the plates on the ground supporting the standards for distributing the load on the ground. Toeboard: These boards are placed parallel to the boarding near the wall, to provide protection to the workers. Transoms: If both ends of putlogs are supported on ledgers, then they are called as transoms.īridle: It is a member used to bridge an opening in a wall, which supports one end of the putlog at the opening.īoarding:The planks on which workers stand. One end of the putlog is supported by the wall and the other by the ledger. Putlogs: These are horizontal members which are perpendicular to the walls. Ledgers: These are horizontal members which are parallel to the wall.īraces:Diagonal members fixed on standards. The platform should be provided with guardrails, in case there is a chance of a worker falling from a height of more than 2 m. Proper care should be taken in scaffolding for outer walls, as the height of a scaffold goes on increasing as the number of storeys increases. The height of the scaffolding is adjusted as the work progresses. It may be provided on both sides or only one side of the wall. Scaffolding is a temporary structure created to facilitate the construction, repair or maintenance of walls when the work is to be carried out at the height of more than 1.5 m.
