Single scaffolding is one of the major types of scaffolding, although not as common. It is also referred to as brick layer’s scaffolding, and is mostly employed in brick masonry.
Its components consist of ledgers, standards, and putlogs. They are placed 1.2 meters from the wall, and are parallel to it. Standards are 2 to 2.5 meters apart from each other. Ledgers are connected vertically to the standards, and are placed 1.2 to 1.5 meters apart. Putlogs are extracted from a hole in the wall and are located 1.2 to 1.5 meters apart. Wooden boards and braces are some of the other components used in a brick layer’s scaffold.
Single scaffolds make the use of putlogs which is why they are also called putlog scaffolds. Putlog scaffolding is used for ordinary buildings, and is not recommended when a complex structure is involved.
The advantage of using a single scaffolding is that its putlogs are connected to the structure being built. This ensures that the scaffold is rigid and much safer comparatively. Free standing scaffolds are prone to falling over in windy weather conditions whereas single scaffold stands its ground.
A putlog scaffold requires lesser components for set up, which makes it simple and easy.
However, there are some drawbacks to using a putlog scaffold. Because it uses the building itself for support, you can erect the next scaffold only after the brickwork has set. This requires some wait, and makes the process of using this scaffold quite slow.
Another drawback is that the putlogs in a single scaffolding leave holes in the wall of the structure. Therefore, even after the building is completed, there are still holes left to fill up.
With a putlog scaffold, you cannot reach a significant height. Keeping all these points in consideration, a single scaffolding does not have any major advantage over the other types of scaffolding systems.
