Different Sorts Of Scaffolding

Definition of scaffolding

The impermanent framework containing platforms at various stages which permits masons to sit and continue their construction work at different height of building is termed as scaffolding. Scaffolding is required for masons to sit and put construction materials when the height of wall, column or any other structural members of a building exceeds 1.5m. It offers a temporary and a safe working platform for different types of work such as construction, maintenance, repair, access, inspection, and so forth.

Divisions of Scaffolding:

There are the following various divisions available:

Standards:

Standards indicate to the vertical member of the frame work that is used to support on the ground.

Ledgers:

Ledgers are the horizontal members which are running equivalent to the wall.

Braces:

Braces are diagonal members running or fixed on the standard to provide stiffness to the scaffolding.

Transoms:

While both the ends of put logs are sustained on ledgers, then they are called transoms.

Boarding:

Boarding is a platform which is horizontal to support workmen and elements which are supported on the put log.

Guard Rail:

Guard rails are supplied at the working level similar to a ledger.

Classification of Scaffolding

Scaffolding can be categorized into various kinds which are described below in a nutshell:

Single Scaffolding

For brick masonry works single scaffolding is widely used. This type of scaffolding contains a single framework of standards, putlogs, ledgers, etc. Standards are placed at a distance of about 1.2m from the wall at 2-2.5 m interval and are attached by ledgers at a vertical interval of 1.2 to 1.5m. One end of putlog is on the ledgers and the other one in the hole left in the wall at an intermission of 1.2 to 1.5m.

Double Scaffolding

Double scaffolding is usually used for stone masonry works. Stipulation of holes to withstand putlogs is tough enough, so double scaffolding is preferred containing two rows of standards segregated by ledgers. The first row of the scaffolding is located at 20-30 cm away from the wall and the next row is kept 1m away from the first row. Transoms are situated on the ledgers and the cross braces in the scaffolding assists to build them more powerful and durable.

Steel Scaffolding

Steel scaffolding is similar to mason scaffolding. It consists of steel tubes instead of wooden members. In such scaffolding, standards are placed at a space of 3m and are connected with the help of steel tube ledgers at a vertical interval of 1.8m.
