Scaffolding is a significant niche in construction, with over 65% of construction employees working in it.
Essentially, a scaffold is a makeshift structure that a building is constructed around. Construction workers also use it as a platform to carry out their work from.
Scaffolding is built of wood or steel. It must be solid enough to sustain workers and other building materials placed on it.
Scaffolding types differ depending on the type of construction. Read on to learn more about scaffolding types.
Single scaffolding, often known as brick layer’s scaffolding, is commonly used for brickwork. A single scaffolding includes standards, ledgers, putlogs, and other items that run parallel to a wall at a distance of 1.2 m.
The distance between standards is about 2 to 2.5m. Ledgers connect the standards at 1.2 to 1.5m vertical intervals. Putlogs are removed from the hole in the wall and placed at one end of the ledgers. These putlogs are spaced at 1.2 to 1.5 m intervals.
As double scaffolding is commonly employed in stone construction, it is also known as mason’s scaffolding. It is tough to cut holes in stone walls to support putlogs. Hence, to make it stronger, two rows of scaffolding are built.
The first row is 20 to30 cm from the wall, while the second row is a meter away from the first. Afterwards, putlogs that are supported by both frames are placed. Rakers and cross bracings are provided to strengthen it. This is also known as independent scaffolding.
Movable tripods and ladders support the working platform in Trestle scaffolding. This is typically used for operations inside a room, up to a height of 5m for painting, repair work, and so on.
Steel scaffolding is made of steel tubes joined together using steel couplers or fittings. It is very simple to assemble and uninstall. It has high durability, strength, and fire resistance. It is, however, not cost-efficient, but it will increase worker safety. As a result, it is widely used today.
Cantilever scaffolding is a type of scaffolding in which the standards are supported by needles inserted through holes in the wall. This is referred to as single frame scaffolding.
Cantilever scaffolding is normally employed in situations such as
- The ground cannot support standards.
- The ground needs to be made traffic-free.
- The upper portion of the wall is being constructed.
Patented scaffoldings are built of steel but are outfitted with unique couplings, frames, and the like. These are premade scaffoldings that are available on the market to be purchased. Working platforms of this scaffolding style are arranged on brackets that may be adjusted to a desirable level.
The working platform in suspended scaffolding is suspended from roofs using wire ropes or chains. It can be adjusted based on the preferred level. Scaffolding of this sort is used for repair work, pointing, painting, and other similar tasks.
Installing a scaffold before construction begins ensures safety and stability for those working on-site. Hence, it is a decision that needs to be made very carefully.
The different types of scaffolding mentioned in this article list the qualities of each type and where to best use them. Nevertheless, it is advised that one consult a construction expert while picking the correct type of scaffolding option.
