Directional Coupler Questions

Putlog and Independent Scaffolding

A putlog scaffold consists of a single row of standards, parallel to the face of the building and set as far away from it as is necessary to accommodate a platform of four or five boards wide, with the inner edge of the platform as close to the wall as is practicable.

The standards are connected by a ledger fixed with right angle couplers and the putlogs are fixed to the ledgers using putlog couplers. The blade end of the putlog tube (or putlog adaptor) is normally placed horizontally on the brickwork being built, taking care to use the maximum bearing area.

A putlog scaffolding differs from traditional independent-scaffolding as it is actually tied into the building bricks using ‘putlogs’ (or tubes) and putlog adapters. Step Scaffolding offers design and traditional putlog scaffolding for private and commercial requirements. All our scaffolders are highly trained and fully qualified and comply with all Government standards.

 

Where a putlog is required for an intermediate board support and it is opposite an opening in the building, such as window or doorway, the inside end of the putlog should be supported on an underslung bridle tube spanning adjacent putlogs. The bridle tube should be secured with right angle couplers.

 

Sway bracing is required at intervals not exceeding 30 M but, unlike independent tied scaffolds, ledger bracing is not required in the finished scaffold.

 

An independent scaffold consists of a double row of standards, with each row parallel to the building. The inner row is set as close to the building as is practicable. The distance between the lines of standards should be the minimum necessary to accommodate the required number of boards and toe boards.

 

A variation may be adopted in which the row of standards nearest to the building can be set back about 300 mm from the building face. This means that one of the boards of the platform can be laid between the inside row of the standards and the building face.Types of Independent Scaffold are: 

Birdcage scaffold: A birdcage scaffold is an independent scaffold that consists of more than two rows of standards in both directions and is connected by ledgers and transoms. It is mainly used for work that is to be carried out on a single level, such as ceilings.

Tower scaffold: A tower scaffold is an independent scaffold consisting of four vertical members connected longitudinally and transversely.

Mobile Scaffold: A mobile scaffold is an independent scaffold that is freestanding and mounted on castors.

Hung scaffold: A hung scaffold is an independent scaffold that hangs from another structure, but is not capable of being raised or lowered when in use.
