Scaffolding can be defined as a temporary rigid structure that is made of bamboo or timber. The primary object of constructing a scaffold structure is to build a platform on which the labourers can work at different heights. A good scaffold structure also helps in lowering the risk of injuries for the employees. The Scaffolds also assists in lifting materials different heights. There are many reputed companies that offer scaffolding services in Cape Town. Different types of scaffolding are being used in the construction sites. Some of the popular scaffolding structures are discussed below:
Brick Layer’s Scaffolding or Single Scaffolding
In this type of scaffolding structure, a series of vertical bamboo or timber (they are also named as standards), are firmly fixed into the ground, parallel to the building wall. The distance in between two standards is generally kept within 2.4 to 3 m. The standards are connected to each other by ledgers. Ledgers are tied with standards at every rise of 4 ft. to 5 ft. Rope lashing is generally used to tie the standard with ledgers.
The putlogs are placed at the horizontal spacing of 120 cm such that the one end is supported on the ledgers and the other end is held in the holes that is made in the wall. Rope is used to fasten the putlogs with ledgers, to provide the proper support.
Mason’s Scaffolding or Double Scaffolding
This type of scaffolding is generally used in building stone masonry. It is usually sturdier and more durable than the brick layer’s scaffolding structure. However, there are some key differences between mason’s scaffolding and brick layers’ scaffolding. When it comes to the brick layer’s scaffolding a single row of standard is fixed into the ground however, for mason’s scaffolding two rows of standards are fixed into the ground.
Tubular scaffolding is generally made of stainless steels. The process of constructing a steel scaffolding is similar to that of brick layers and mason’s scaffolding. The gap between the two standards are generally kept within 2.5 m to 3 m. These standards are fixed on a square or round steel plate by means of welding. The ledgers are generally spaced at every rise of 1.8 m. Length of the putlogs are normally kept in between 1.2 m to 1.8m. One of the major benefits of using steel scaffold structures is that it can be erected or dismantled in a rapidly in comparison to timber or bamboo scaffolding. It is also more durable than timber. Thus, this type of scaffoldings is cost effective in the long run. Moreover, their fire-resistant capacity is higher than the other scaffolding structure. They are more suitable and can be accessed at any height.
Needle Scaffolding or Cantilever Scaffolding
In this type of scaffolding, the standards are not fixed into the ground, rather they are placed at some height above ground level. The platform on which the stands are kept is known as the needle. A needle is a cantilever structure that is made of timber.
These were some of the most common kinds of scaffolding which is available and increasingly used in the construction industry.
