Scaffolding is a temporary rigid structure made of stable, bamboo or wood. The primary purpose of scaffolding is to create a platform on which masons can work at different heights. Scaffolds also help in lifting materials for immediate use at various heights.

The following 4 types of scaffolding are generally used in building construction work.

  1. Brick Scaffolding or Single Scaffolding
  2. Mason’s Scaffolding or Double Scaffolding
  3. steel or tubular scaffolding
  4. Needle Scaffolding Or Cantilever Scaffolding

1. Single Scaffolding / Brick Layer Scaffolding

In this type of scaffold, a series of vertical members made of bamboo or wood (designated as standards), rests firmly in the ground in a row parallel to the wall of the building. The distance between the two standards is usually kept within 2.4 to 3 meters.

These standards are connected to each by a longitudinal horizontal member (named .) bookkeeping) ledgers are bound to the standards at each increment of 120 cm to 150 cm (ie 4 ft to 5 ft). Rope lashing is used to attach the standard with the lasers.

putlog (or transverse horizontal members) are placed at a horizontal distance of 120 cm such that one end rests on the lasers and the other end is in the holes in the wall. Rope lashing is used to attach the putlogs to the laser.

If the height of the scaffold is too high, in order to maintain its stability, sometimes the diagonal member (as in the name) braces) is given. The braces are crossed diagonally and fitted with the standards using rope lashing.

2. Double Scaffolding / Mason’s Scaffolding

This type of scaffold is commonly used in case of stone masonry. It is stronger than brick layer scaffolding.

The primary differences between brick layer scaffolding and mason scaffolding are as follows:

  • In case of brick layer scaffolding the single row of standard is fixed in the ground. But in case of masons scaffolding two rows of standards are fixed in the ground. The first row of standards is fixed close to the wall and the second row of standards is fixed at a distance of 1.5 m from the first row. That is why it has been named as Double Scaffolding.
  • In case of brick layer scaffolding one end of the putlog is fixed with the wall. But in double scaffolding, the putlogs are not fixed with the wall. Put logs are supported on ledgers at both ends. Therefore the mason’s scaffolding is completely independent of the wall surface. And no need to make any holes on the wall surface.

3. steel or tubular scaffolding

The construction method of steel scaffolding is similar to that of bricklayer and mason scaffold. the primary differences are

  • Instead of using wood, steel tubes of 40 m to 60 mm diameter are used
  • Rope fastening is used instead of using special type of steel joints for fastening.
  • Standards are mounted on the base plate rather than fixed in the ground

The gap between two standards in a row is generally kept within 2.5 m to 3 m. These standards are fixed on a square or round steel plate (known as base plate) through welding.

The lasers are spaced at each increment of 1.8 metres. The length of the putlog generally ranges from 1.2 m to 1.8 m.

The advantages of steel scaffolding are as follows:

  • This may happen erected or destroyed more rapidly Compared to wooden scaffolding. It helps in saving construction time.
  • it’s more durable compared to wood. Hence it is economical in the long run.
  • there’s more to it fire resistant Capacity
  • it’s more suitable and safe To work at any height.

4. Needle Scaffolding / Cantilever Scaffolding

Needle scaffold or cantilever scaffold is required in the following cases:

  • When it is not possible to set standards in the ground
  • When construction is carried out on the side of a busy road
  • When construction work is done at very high level in case of tall building

In this type of scaffolding, the standard is placed at some height above ground level instead of being mounted in the ground. The platform on which the stands are kept is called Needle, A needle is a cantilever structure, made of wood, that is projected from a hole in a wall.

To prevent the needle from lifting, the inner ends of the needles are supported by struts between the needles and the head pieces.

The projected outer end of the needle is supported by an inclined strut that rests on the window sill.

The joints between the inclined strut and the needle are clamped through dogs,
