Standards

Ledgers

  • Horizontal member parallel to walls.

Putlogs

  • These move the transverse pieces which do place toward ledgers at one end.
  • And supported on the walls at another end
  • They are right angles to the walls.

Transoms

Guard rail

  • These are a rail provided like a ledger at the working level.

Braces

Toeboard

  • These are a board placed parallel to the ledgers & supported between the putlogs.
  • It does provide to operate as a protective measure on the working principles.

Raker

  • These are an inclined support

Types of Scaffolding

  1. Single or Brick-layer’s scaffolding
  2. Double or Mason’s scaffolding
  3. Steel or tubular scaffolding
  4. Cantilever or Needle scaffolding
  5. Wooden scaffolding
  6. Suspended scaffolding
  7. Trestle scaffolding

Single or Brick-layer’s scaffolding

Double or Mason’s scaffolding

  • It is difficult to leave holes in the stone masonry
  • To provide a bearing for the putlogs, in mason’s scaffolding two frames of standards, ledgers, and braces are used. One is placed close to the wall and the other at a distance of 1.5 m from the first one. Hence the mason’s scaffold is completely independent of that stone wall.

Steel scaffolding

  • Steel scaffolding is similar to that of timber scaffolding.
  • The wooden members are replaced by 40 mm to 60 mm diameter steel tubes.
  • Special types of steel couplets or fittings are used for connecting different members.
  • In that type, the vertical tubes known as uprights either standards are spaced 2.5 to 3 m apart.

Cantilever or Needle scaffolding

  • When scaffolding is to be provided for a building on the side of a busy street where the construction of ordinary scaffolding will obstruct the traffic on road.
  • The scaffolding is erected from window corners or string courses employing projecting needles.
  • A needle is a timber beam that cantilevers out through the holes cut in the wall.

Trestle scaffolding

  • A framework in the form of a horizontal member supported at each end by a pair of splayed legs used to carry scaffold boards, a tabletop, etc.
  • Working platforms consisting of metal trestle (support frame with a tripod or inverted V form) and horizontal planks or metal decking. Parts can also be made of wood. They can be used up to 3 meters high. When used on balconies, terraces or in the vicinity of openings with a risk of more than 2 meters falls, collective protection (railings, nets, etc.) must be used.
