Scaffolding is a temporary structure used are widely used on site to get access to heights and areas that would be otherwise hard to get to. Scaffolding might be dangerous which may result to serious injury or death.
Scaffolding is typically formed from simple, repeating systems of tubes, joints and boards that provide a temporary safe
working platform for activities such as; construction,
maintenance, repair, access, inspection and so on. In addition,
scaffolding is just a provisional structure which is used to provide support to the original structure and at the same time, it also functions as a platform for the workers to perform the construction works. According to the type of construction work, the type of scaffolding will differ. It advisable and important for a scaffolding to be well-built, strong and firm to support workers and other construction material laid on it. Either of steel or timber, scaffolding is made up of. Scaffolding are suitability and stable, if they are made up of steel or timber due to their ability to withstand the impose loads.
Types of Scaffolding
The following listed below are the types of scaffolding. They are:
- Single scaffolding
- Double scaffolding
- Suspended scaffolding
- Steel scaffolding
- Cantilever scaffolding
- Trestle scaffolding
- Patented scaffolding
1. Single Scaffolding: This type of scaffolding is generally used for brick masonry. It is also known as brick layer’s scaffolding. Single scaffolding consists of standards, ledgers, putlogs etc. It is parallel to the wall at a distance of about 1.2 m. Distance between the standards is about 2 to 2.5 m. Ledgers connect the standards at vertical interval of 1.2 to 1.5 m. Putlogs are taken out from the hole left in the wall to one end of the ledgers. Putlogs are positioned at an interval of 1.2 to 1.5 m.
2. Double Scaffolding: This type of scaffolding is normally used for stone masonry job, which is also called mason’s scaffolding. Double scaffolding is also known as the independent scaffolding. In stone wall, two scaffolding row are needed when trying to construct a hole in a stone walls, due to it strength. The first row is about 20 to 30 cm distance to the wall and the other is 1m distance to the first row. The function of cross braces and rakers is to make the putlogs stronger.
3. Suspended Scaffolding: In this type of scaffolding the working platform is suspended from roofs and it is mainly used for painting, pointing, repair works and etc. with the help of chains and wire ropes. It can be lowered or lifted to the entreat level.
4. Steel Scaffolding: This type of scaffolding are easy to make and dismantle, it is constructed by steel tubes and are fixed together with the steel couplers and fittings. Steel scaffold is more safe but not economical. It is frequently used due to it greater strength, higher fire resistance and greater durability.
5. Cantilever Scaffolding: This type of scaffolding is also known as frame type scaffolding. It is supported on series of needles which are taken out through holes in the wall while the other needles are protrude inside the floor through the openings. It can also be called double frame or independent scaffolding.
6. Trestle Scaffolding: In this type of scaffolding, the working platform is supported on movable tripods or ladders. This is generally used for work inside the room, such as paintings, repairs etc., up to a height of 5m.
7. Patented Scaffolding: This type of scaffolding are readymade which are available in market. It is made up of steel but they are made with special couplings and frames. It working platform is arranged on brackets which can be adjustable to our required level.
