Suspended scaffolding is mainly used for different types of construction projects and maintenance jobs like paintings, repair works, window cleaning, etc. These scaffolding platforms can be moved vertically as well as horizontally when required. It can be raised or lowered to the required level. Counterweights are used to prevent overturning. Anchor plates should be tied with U bolts. In suspended scaffolding, two or more platforms are suspended by ropes, wires, or chains from overhead outriggers anchored to the building. It is mainly used for outdoor construction and bigger structures. It is one of the most popular scaffolding widely used these days. Steel scaffoldings are more expensive and it requires more skilled labor and also needs repainting from time to time to keep their color and protect it from damage. Because of greater strength, it can be used for greater heights. The steel scaffolding structure provides It has greater strength, greater durability, and high fire resistance. It can be assembled or dismantled more quickly than others. Steel scaffolding is constructed by steel tubes that are fixed together by steel couplers. These types of scaffolding can be easily shifted from one place to another and mounted with wheels. This is generally used work inside the room, such as paintings, minor repairs, etc and It is used up to a height of 5m. In Trestle scaffolding, the working platform is supported on tripod-type movable ladders with no standards, putlogs, etc. Cross braces and rakers can also be added at a later stage to make the structure stronger. In stone walls, it is tough to make holes in the wall for supporting putlogs so two rows of standards are separated by ledgers for better support and strength.īasically, the first row is about 20 to 30 cm away from the wall, and the second one is 1m away from the first row. With the support of both frames then putlogs are positioned. Double Scaffoldingĭouble Scaffolding is generally widely used for stone masonry works, therefore it is also known as mason’s scaffolding. This scaffolding type is generally stronger and provides better support for construction works as compared to single scaffolding. This type of scaffold is only suitable for new work in bricks or blocks. putlogs are set at a fixed distance of 1.2 to 1.5 meters and are extracted from a gap in the wall at the end of the ledger. At a vertical interval of 1.2 to 1.5 interval ledgers are connected to standards.
Distance between the Standards is 2 to 2.5 meters apart from each other. They are corresponding to the wall at a distance of around 1.2 m. Single scaffolding consists of a single framework of standards, ledgers, putlogs, etc. Single scaffolding is also called bricklayer scaffolding and is mostly employed in brick masonry.
