Putlog Scaffolding System: What is it used for?

When using the putlog scaffolding system, holes on the wall of the structure act as the support for the entire scaffolding structure. A single leader and a single row of standards are used to erect the scaffolding. The term bricklayers scaffold, which is another name given to this scaffolding method, is a term derived from the fact that the scaffolding structure is attached to the wall of the building which is bricks.

This scaffolding system is quite popular since it only requires a few components to set up compared to an independent scaffold. With regards to its safety, a putlog scaffold is safer to use compared to other methods of scaffolding since it is linked to the building itself for support.

One of the major drawbacks of using this scaffolding method is that the construction work has to wait for the brickwork to be set for the putlogs to be inserted. The putlogs also leave holes on the structure walls which gives the construction workers an added task of having to go back and fill all the holes. This ends up extending the period upon which the construction project will be completed.

Components of a putlog scaffolding system

There are several different components that make up the entire putlog scaffolding system. These are:

The putlog

A putlog is a transom that has been flattened on one side. The flat end of the putlog is placed in the hole on the wall and then connected to horizontal tubes with the help of a single coupler.

Ledgers

Ledgers are the link between two standards normally fixed with the help of a double or right-angle coupler.

Standards

These are vertical tubes used to set up the scaffolding structure.

Right angle couplers

A right angle or double coupler is used to link tubes of the scaffolding at a 90° angle.

Putlog coupler

A putlog coupler is what links a transom tube and the ledger tubes.

Installing putlog scaffolding

The first thing to do is to leave the holes in the building structure into which the flat ends of the putlogs will be inserted. You will then insert a putlog to each of the spaces and connect standards and ledgers using the double couplers.

Fix the putlogs on the ledgers using single couplers and place the boards that will serve as working platforms across the putlogs. You are then required to insert two rows of horizontal tubes which will serve as the working platform.

With the modernization of scaffolding methods, the popularity of putlog scaffolding has reduced with time. However, it is still a very safe method to use where applicable.
