Trestle scaffolds generally do not require a licensed scaffolder to erect or dismantle. Trestle scaffolds, for example ‘A-frame’ and ‘H-frame’ trestle scaffolds, are commonly used by bricklayers, plasterers and painters and for general fit-out and finishing work.
Suspended ScaffoldingĪ trestle scaffold is assembled from prefabricated trestles, braces and accessories. This is ideal for painting, repair works and window cleaning – all jobs that may take a day or less to complete and only require a platform and easy access. It is a working platform that is suspended from a roof with wire rope or chains and can be lifted and lowered when needed. Suspended scaffolding consists of a platform suspended from above by cables and stirrups on each side of the platform or a single basket with one motor. It is also used when there is no hard firm ground to support the standards, for instance, when construction work is carried out on busy streets and where the construction work is done at great heights on a multi-storied building.

It is used when obstacles are preventing a scaffolding tower being erected such as the ground can’t support standards, the ground near the wall needs to be free from traffic or the upper part of the wall is under construction. Double ScaffoldingĬantilever scaffolding is a form of scaffolding that is usually used to overcome obstacles that prevent a scaffolding tower from being erected or reduce the chances or damage occurring to the structure beneath the cantilevered area. Then, putlogs are supported at both ends on ledgers making them completely independent of the wall surface. Instead, two rows of scaffolding are required, the first is fixed close to the wall and the second is fixed some distance from the first. It is commonly used for stone masonry because it is hard to make holes in stone walls to support putlogs. This scaffolding type is generally stronger and provides better support for construction works. Notice that a single row of standard is normally fixed to the ground in the case of brick layer’s scaffolding.It is widely used for stone masonry works.
Single Scaffoldingĭouble scaffolding differs from single scaffolding in that it features two rows of standards separated by ledgers for better support. Putlogs are positioned at a gap of 1.2 to 1.5 m. Putlogs are extracted from the gap remaining in the wall to one end of the ledgers. Ledgers join the standards at an upright gap of 1.2 to 1.5 m. The distance amongst the standards is around 2 to 2.5 m. Single scaffolding comprises standards, putlogs, ledgers etc., which corresponds to the wall at a distance of around 1.2 m. Single scaffolding is usually used for brick masonry and so it is also known as brick layer’s scaffolding. Types of Scaffolding Used in Construction: It consists of one or more planks of convenient size and length, with various methods of support, depending on the form and use. Scaffolding is a temporary structure used by workmen when renovating, maintaining, repairing or cleaning a building that aims to keep them safe, give them easy access and allow for improved efficiency.
