Scaffolding is a temporary elevated platform used to support workers and materials during construction or repair of buildings. The main parts include standards, ledgers, braces, putlogs, transoms, boarding/working platforms, and guard rails. Common types are bricklayer scaffolding, masonry scaffolding, cantilever scaffolding, suspended scaffolding, trestle scaffolding, and steel scaffolding. Cantilever scaffolding uses needles projecting from openings in walls to support the scaffolding. Suspended scaffolding involves suspending the working platform from roofs using wires or chains.

1. SCAFFOLDING

2. SCAFFOLDING
• A temporary elevated platform and
its supporting structure used for
supporting worker, materials, or
both" in the construction or repair of
buildings and other large structures

3. parts
• 1.standards : vertical members, supported
on ground
• 2.ledgers: horizontal members , running
parallel to the wall
• 3.braces: diagonal members fixed on
standards
• 4.putlog : transverse members , placed at
right angle to wall , one end supported on
ledger and second on the wall
• 5.transoms : they are putlogs whose both
ends are supported on ledgers

4. parts
• 6. Bridle : member used to bridge wall
opening
• 7. Boarding/Working Platform :
horizontal platform to support workmen
, material , supported on putlog
• 8. Guard rail : rail provided at working
level for safety purpose
• 9. Toe board : boards placed parallel to
ledgers and supported on putlogs

5. Types of scaffolding
1. Brick layer scaffolding / single scaffolding
2. Masonary scaffolding / double scaffolding
3. Cantilever Scaffolding
4. Suspended scaffolding
5. Trestle scaffolding
6. Steel scaffolding

6. Brick layer scaffolding

7. • Consists of –
– Vertical members at 2.4 to 3.0 m interval fixed
in ground
– Horizontal members 1.2 to 1.5 m
– Put logs are at 90° with respect to wall.
– One end of put log in to hall created in wall
and other end on horizontal members
– Length of putlog – 90 cm and spacing 1.2 m
– Putlogs are provided to support working
platform
– For high scaffolding cross bracings are
provided

8. Masonary scaffolding
• In stone masonary - not feasible to provide holes in
the wall to support putlogs
• So, frames of
– vertical ,
– horizontal and
– braces are used
• First frame/vertical members known as standards is
placed near to wall , other at 1.0 m from the first in
series
• Then horizontal members/ ledgers are fixed with
frames / vertical members.
• Putlogs are supported on horizontal members only
• Working platform is provided on Putlogs
• generally used for stone masonry

9. CANTILEVER SCAFFOLDING

10. Cantilever or Needle scaffolding
• It may be brick layer’s type or masonary type
• For brick layer type :
• Vertical member are supported on series of
needle taken out through openings or holes in
wall
• For masonary type:
• needles /projecting beam are strutted inside
the floor through openings
• Used :
• When the ground does not having the capacity
to support standards,
• When the Ground near the wall is to be free
from traffic,
• When upper part of the wall is under
construction.

11. Suspended scaffolding
• In suspended scaffolding, the
working platform is suspended
from roofs with the help of wire
ropes or chains etc.,
• it can be raised or lowered to
required level.
• This type of scaffolding is used for
– repair works,
– pointing,
– paintings etc..

12. Trestle scaffolding
• Working platform is
supported on movable
ladders , tripods
• Useful for minor repair
work and/or painting work
inside the room for 5.0 m
max. height from surface.

13. Steel scaffolding
• Steel tubes are used of 40 to 50
mm dia. And 5 mm thick having
standard length
• Special couplings are used to fix
steel tubes
• Frame of horizontal , vertical and
cross steel tubes are created
• Fire resistance ,Strong , durable ,
erection & dismantle is easy , used
for any height
• High initial cost & require
maintenance as painting
