Thank you for the presentation on scaffolding. I learned about the different types of scaffolds used in construction such as brick-layer's scaffolds, mason's scaffolds, steel scaffolds, needle scaffolds, and wooden scaffolds. Each type has a specific design and use depending on the construction needs. Proper scaffolding is important for safely supporting workers and materials during building.

3. DEFINITION
 “A temporary elevated platform and its
supporting structure used for supporting
workmen, materials, or both” in the
construction or repair of buildings and
other large structures.

4. TYPES OF SCAFFOLDS
 The following different types of scaffolds are in common use:
1. Brick-layer’s scaffolds.
2. Mason’s scaffolds.
3. Steel or tubular scaffolds.
4. Needle scaffolds.
5. Wooden scaffolds.

5. BRICK-LAYER’S SCAFFOLDS
 It consists of vertical members called
standards at 2.4 to 3 m apart. The
standards are connected by ledgers.
 Transverse horizontal members called
putlogs are lashed on the ledgers at
one end and into the holes in the
wall at the other end.
 In high scaffolding, cross braces are
invariably used to stiffen the
temporary structure.

6. MASON’S SCAFFOLD
 In mason’s scaffold 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.
 Thus the mason’s scaffold is
entirely independent of the stone
wall.

7. STEEL SCAFFOLD
 Steel scaffold consists of steel tubes of
38mm to 64mm diameter and steel
couplets or fittings.
 In this type of scaffold the vertical tubes
called uprights or standards are spaced
2.5 to 3 m apart.
 Ledgers connecting the standard are
spaced at 1.8m vertically apart and
putlogs have special ends to fit into the
joints in the wall.
 Tubular scaffolding mounted on wheels
can be used for carrying out the work of
painting the walls, under side of roofs etc.

8. NEEDLE SCAFFOLDS
 Needle scaffold is used for a building on
the side of a busy street.
 The scaffold is erected from window
corners by means of projecting needles
(timber beams)
 From inside the needles are supported
on sole pieces and the projected end of
needle is supported by an inclined strut.
 The joint between the inclined strut and
the needle is clamped by means of
dogs.

9. WOODEN SCAFFOLDS
 There are two different types of wooden scaffold:
1. Gantry with travellers or crane
2. Platform gantry

10. GANTRY WITH TRAVELLERS
 When the stone blocks used in the wall
construction are too heavy crane
travellers are used.
 The framework of gantry consists of
timber standards raised on either side
of wall.

11. PLATFORM GANTRY
Platform gantry is adopted in stone masonry
construction as it can be used independent
of wall.
The gantry consists of vertical posts fixed to
common sole piece at its base and to a
head pieces at the top.

12. CONCLUSION
 In construction work the term “scaffold” is very important
Because during a construction without scaffolding, can not
be completed properly.
 Proper care must be taken in making scaffold because a
good scaffold can hold the workers and other necessary
materials together.
 So when we will be able to make a proper scaffold, only
after then we can build a proper building.
