Single scaffolding uses vertical supports known as standards to be able to stand parallel to the wall of a structure. The horizontal supports known as ledgers are connected to the standards at a vertical angle that is even. The scaffolding is connected to the building for support through holes called putlogs. Brick masonry is the most common use for single scaffolding.
The main difference between single and double scaffolding is that only one layer of standards is used for single scaffolding, while double scaffolding uses two layers of standards.
The two also differ in their primary use, as the single scaffolding method is commonly used for brick masonry while double scaffolding is common in stone masonry. This method is common in stone masonry as the stone is quite rigid, making it difficult to make holes for putlog anchoring.
Advantages of single scaffolding
When single scaffolding is used, the scaffold structure is much more rigid, making it more resistant to adverse weather and much safer for construction workers. Single scaffolding involves the use of fewer parts and is, therefore, cheaper compared to double scaffolding.
Single scaffolding also has its disadvantages such as not being able to be used in stone masonry, unlike double scaffolding. It is also unsafe to use for heights above 2.0 metres and is time-consuming as the putlog holes must be filled after the scaffold structure is moved.
