Different types of scaffolding in construction

Scaffolding belongs to a temporary structure to provide support to the original structure. Besides, the construction professionals apply as a base to conduct the construction works.

Different types of scaffoldings are available on the basis of the types of construction works. Scaffolding is formed with timber or steel. It should be durable and strong to provide support to construction workers as well as other construction material arranged on it.

Types of Scaffolding placed in Construction: Single scaffolding, Double scaffolding, Cantilever scaffolding, Suspended scaffolding, Trestle scaffolding, Steel scaffolding, Patented scaffolding

Single Scaffolding: Single scaffolding is usually applied for brick masonry and is known as brick layer’s scaffolding. Single scaffolding includes standards, ledgers, putlogs etc., that is parallel to the wall and away from each other about 1.2 m. Distance among the standards is about 2 to 2.5 m. Ledgers join the standards at vertical distance of 1.2 to 1.5 m. Putlogs are extracted from the hole left in the wall to one end of the ledgers. Putlogs are arranged at a distance of 1.2 to 1.5 m.

Double Scaffolding: Double Scaffolding is usually intended for stone masonry and it is also described as mason’s scaffolding. In stone walls, it becomes difficult to create holes in the wall to support putlogs. Therefore, two rows of scaffolding are built up to enhance their strength. The first row is 20 – 30 cm distant from the wall and the other one is 1m distant from the first row. After that putlogs are arranged being supported with the both frames. Rakers and cross braces are used to improve the strength. This is also known as autonomous scaffolding.

Cantilever Scaffolding: Under this a type of scaffolding, support is given to the standards by a series of needles and these needles are extracted through holes in the wall. This is known as single frame type scaffolding. In the other type needles are strutted inside the floors through the openings and this is known as independent or double frame type scaffolding. while developing cantilever scaffolding, proper care should be initiated.

Usually cantilever scaffoldings are applied in the following conditions :-

If the ground does not contain the capability to support standards,
If the ground near the wall is to be free from traffic,
If the upper part of the wall is going on.
