Scaffolding is a temporary structure made up of timber, still or bamboo used to support the construction workers working with different heights. It should be strong enough to support workmen and other construction material placed on it.
Safety is the main priority while undertaking any construction work, and therefore with the help scaffolding, the construction workers get to work in a secure workplace. Even if the construction is taking place in the public area, scaffolding equipment not only benefits the workers but provides safety to the public as well.
Another major advantage of scaffolding is that it produces a well-balanced flat platform which makes navigation for workers easier. This way multiple workers can work on-site.
No matter how big or small the project may be, the safety of workers is always a concern and with the help of scaffolding, workers can work on a safe and secure platform, reducing the chances of mishappening.
Below are different types of scaffolding:
1) Single scaffolding: Single scaffolding also known as brick layer’s scaffolding, is mostly used for brick masonry. It includes standards, ledgers, putlogs, etc. The distance between standards is about 2 to 2.5 m and the ledgers connect the standards at a vertical interval of 1.2 to 1.5 m. Also, the putlogs are obtained from the hole left in the wall to one end of the ledgers and they are placed at an interval of 1.2 to 1.5 m.
2) Double scaffolding: Double scaffolding is often called mason’s scaffolding and is used for stone masonry. Since they are stone walls, therefore it is hard to make holes in the wall to support putlogs. So, in order to make it strong, two rows of scaffolding are constructed.
The first row is 20 – 30 cm far from the wall and the other one is 1m far from the first row. The putlogs are installed which are supported by both the frames. Also, to make it more strong and enduring rakers and cross braces are provided.
3) Cantilever scaffolding: Cantilever scaffolding in particular is that type of scaffolding where the standards are supported on series of needles and then these needles are taken out through holes in the wall. This is referred to as single frame type scaffolding.
In the other type, needles are strutted inside the floors via openings and this is called independent or double frame type scaffolding. Extra care should be taken while construction of cantilever scaffolding.
Mostly the cantilever scaffoldings are used in the conditions where the ground cannot support standards or the ground near the wall is to be liberated from traffic and the upper part of the wall is under construction.
4) Steel scaffolding: Steel scaffolding is considered stronger as compared to other types of scaffolding and it has greater durability and high fire resistance. It is made up of steel tubes which are attached together by steel couplers or fittings. Also, it more recommended in terms of safety and is extensively used nowadays.
