Scaffolding | Types and Components parts of Scaffolding

Scaffolding

  • Scaffolding is a temporary rigid structure that should platform raised as some building increases inside height.
  • Applied during the mason to work at different stages about a building
  • To provide the materials for immediate use at various heights.
  • When the height of the floor level exceeds 1.5 m.
  • Generally made up of timber.
  • Valuable in construction, demolition, maintenance about repair work.

Components parts of scaffolding

  1. Standards
  2. Ledgers
  3. Putlogs
  4. Transoms
  5. Braces
  6. Guard rail
  7. Toeboard
  8. Raker

Standards

  • Certain are some vertical members of the framework.
  • Both are supported on the ground or drum about embedded into the ground.

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 at right angles to the walls.

Transoms

  • Certain are putlogs but their both ends are supported by moving the ledgers

Guard rail

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

Braces

  • Those are diagonal cross pieces fixed toward the standards.

Toeboard

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

Raker

  • These are inclined to support

Types of Scaffolding

  1. Single or Bricklayers 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 Bricklayers scaffolding

  • It consists of vertical members called standards firmly secured on grounds at 2.4 to 3 m.
  • Some standards are connected to various others by longitudinal horizontal members known as ledgers at every rise of 100 to 150 cm.
  • They are provided on the building site of the standards
  • Transverse horizontal members are called putlogs & they are resting on the ledgers at one end and into the holes in the wall at the other end.
  • Putlogs are 90 cm. in length and are generally spaced 120 cm. apart
  • They are provided to support the working platform.

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.
  • SpParticularypes of steel couplets or fittings are used for connecting different members.
  • In that type, the vertical tubes known as uprights either standard 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 scframeill obstructs the traffic on the 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.

Suspended Scaffolding

  • This is a very light type of scaffolding
  • Used only for maintenance work
  • Such as painting, pointing, whitewashing, distempering, etc
  • The working platform is suspended from the roof employing ropes, wires or chains
  • The platform can be raised or lowered
  • It does not create any obstruction on the ground.

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 consist 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 of falls, collective protection (railings, nets, etc.) must be used.
