Putlog Scaffolding System

Also known as a bricklayer’s scaffold, the putlog scaffolding system involves using the wall of a structure being built as support for the working platform. Putlog scaffold is derived from old masonry – the hole in the wall of a structure under construction is where you ‘put the log’. Because this scaffolding system consists of one row of standards, it is also referred to as single scaffolding.

Putlog Scaffolding System

Introduction

Putlog scaffold is erected by using a single row of standards and a single ledger. Putlog itself is a component of this scaffolding system, and acts as a link between the ledger and the wall of the building. The wall of the building, at this stage, is basically just brick. Hence, the term bricklayer’s scaffold.

The best thing about this scaffolding system is that it does not require as many components as an independent scaffold. It uses the building’s wall for support. Moreover, it is more rigid as compared to other scaffolding systems, because it is connected to the building itself. This makes the scaffold stand stable, even in windy situations.

But like everything else in life and in construction, this scaffolding has its own drawbacks. It slows down work, because personnel have to wait for the brickwork to set before they can insert a putlog. Secondly, the holes left by putlogs have to be filled in when the scaffold is removed, and the building is for the most part complete. Therefore, it delays the completion of the construction project.

Components

Putlog

This is a transom with a flat end on one side. The flattened end enables the putlog to rest in the hole in a wall. These are connected to ledger or horizontal tubes with the help of a putlog or single coupler.

Standards (upright tubes)

As obvious from the name, these are vertical tubes of the scaffolding system.

Ledgers (horizontal tubes)

These are the horizontal tubes that help erect the scaffold. A ledger is the link between two standards. Ledger is fixed using right angle or double coupler.

Double/right angle coupler

Double couplers serve to link two tubes at an angle of 90 degrees.

Single/putlog coupler

Single coupler serves as a link between putlog/transom tubes and ledger tubes.

Putlog heads

The purpose of a putlog head is to turn a standard tube into a putlog, so it can be used in the scaffold system.

Installation

  1. Leave a spot/space in the brickwork at required distances for the flattened end of the transom.
  2. Insert a putlog into each space.
  3. Connect standards and ledgers using double couplers.
  4. Place the putlogs on the ledgers and fix in place using single couplers.
  5. Place boards across the putlogs to create a working platform.
  6. Insert two rows of horizontal tubes to serve as a guardrail.

General Information

When engaging in a refurbishment, renovation, or maintenance project, the flattened or blade end of a putlog can be inserted in a raked out joint in the wall.

For new projects that begin from scratch, putlog is positioned on a wall at the required height, and the remaining wall is built around this point.

It is imperative that the scaffold lift progresses or is raised in accordance with masonry work. Needless to say, work is not possible if the wall keeps progressing while the scaffold remains in its initial position.

Moreover, this scaffold only allows work on the exterior of the building as it gathers support from the external wall.

Putlog scaffolding is not as popular as it used to be. The reason for this is the modern procedures and scaffolds that have revolutionized the construction industry as well as other industries that employ scaffolds.
