7 different types of Scaffolding
Scaffolding can be used according to the types of building constructed. In the process of construction, 7 types ofScaffolding Stevenage are used:
- Single scaffolding: they are also known as Brick-layer-scaffolding. These types of scaffold mainly consist of a single framework of ledgers, standards, and putlogs. They are built parallel to the wall of the building at a distance of about 1.20m. At every 2 to 3 m of intervals standards are placed. Ledgers are assembled with standards at the vertical interval of 1.2m to 1.5m. On one end putlogs are placed at the right angle on the wall and the other on the ledger. This type of scaffolding is popularly used for brick-laying.
- Double Scaffolding: it is also known as the mansion’s scaffolding. The buildings which are made of stone are very difficult to drill to support putlogs. Therefore two scaffolds are used in this case to make the base strong. Each row forms a separate vertical framework each 20 to 30 cm apart from the main wall. Both the frames are now supported by putlogs. Besides, cross braces and rakers are also connected to make them sturdy and stable. They are also called independent scaffolding.
- Cantilever scaffolding: this is also known as needle scaffolding. This needle supports the entire scaffold. There are certain circumstances where this type of scaffold can be used:
- When the ground on which the building is to be constructed is too weak to hold a scaffolding
- When the project is to be done on the road or street that cannot be obstructed
- When the maintenance or construction is to be done at a great height
A needle is made of timber which is extended from the holes of the wall. It also strutted inside the floor by making an opening. This is fully bracing from all sides to prevent it from tripping over. Workers working in the cantilever must have a safety harness for maximum safety. The main components of needle scaffolding are the platform, toe board, protective rails, and monarflex sheeting.
- Suspended scaffolding: this type is mainly used for works such as pointing, painting, etc. this scaffold is connected with wire ropes or chains to the working platform and is suspended from the roof of the building. As it is a lightweight scaffold, it can easily be lowered or raised according to the required level.
- Trestle scaffolding: These types of scaffolds are mainly used inside the rooms for painting and repairing works. Rooms must be not more than 5m in height. It is supported on movable contrivances such as a ladder mounted on wheels.
- Steel scaffolding: In steel scaffolding, rather than using wooden members, steel tubes and couplets are used instead of rope lashings. They are erected and dismantled rapidly. Nowadays, it is also used in high rising buildings because of its strength and durability and well fire resistance. Though the initial cost is more it is salvage is high. It can both be used in stone or brick walls.
- Patented scaffolding: These are arranged with special coupling, frames, etc. They are made with steel. These working platforms are supported on brackets that can easily adjust at any suitable height.
