2. Partition walls are vertical dividers
PARTITION WALLS
FUNCTION
• Separate building internal spaces
into rooms and circulation areas
like corridors.
????????
• If partition walls are load bearing
then they are called as ‘internal
wall’.
• Partition walls are designed as non-
load bearing walls. It may be of
folding, collapsible or fixed type.

3. • Divide the whole area into a number of rooms.
• Provide privacy to the inmates from sight and sound.
• Are light in weight and cheaper in cost of construction.
• Occupy lesser area
• Easily constructed in any position.
ADVANTAGES OF PARTITION WALLS

4. REQUIREMENTS OF A GOOD PARTITION WALL
• Thin in cross-section so that maximum floor area can be utilized.
• Provide adequate privacy in rooms both in respect of sight and sound.
• Constructed from light, sound, uniform, homogeneous, durable and sound insulated materials.
• Simple in nature, easy and economical in construction having proper coherence with the type of building structure.
• Offer sufficient resistance against fire, heat, dampness, white ant or fungus, etc.
• Rigid enough to take the vibrations caused due to loads.
• Strong enough to support sanitary fittings and heavy fixtures.

3.Glass partitions wall
4.Concrete partitions wall
5.plaster slab partition wall
6.Metal lath partition wall
7.A.C. sheet or G.I. sheet partitions wall
8.wood-wool partition wall
9.Timber partitions

6. BRICK PARTITION WALL
Brick partition wall Reinforced brick Brick nogging partition wall
•It is constructed from plain bricks, and it is common
and cost effective
•The bricks are laid as stretchers in cement mortar.
•Thickness of plain brick partition wall is 10cm or half
a brick.
•Recommended height is maximum 2m for
construction in a day
•It is plastered on both sides
•Strong and fire resistant if the brick wall is
constructed properly
•Reinforcements, which is in from of wire
mesh strips or iron bare, are placed at
every third or fourth course.
•Reinforced wire strip width ranges from
25mm to 28mm and thickness is 1.6mm.
•Steel bar diameter is 6mm
•The thickness of the wall equal to 10cm
or half a brick
•This type of partition wall used when
better longitudinal bond is need and
when the partition wall has to support
other super imposed loads
• Brick nogging partition wall
consists of brickwork built up
within a framework of wooden
members.

7. CLAY AND HOLLOW BLOCK PARTITION WALL
• Hollow concrete block partitions are built of individual units of concrete.
• Clay blocks used are well prepared from clay or terra-cotta, and they are either solids or hollow.
• Hollow clay blocks of section 30*20 cm with thickness varying from 5 cm to 15 cm can also be used.
• The blocks are provided with grooves on top, bottom and sides, surfaces are kept glazed in different colures
• They do not change their volume and are in lighter in weight.

8. • the wall is built from precast concrete slab units
• precast unit thickness ranges from 25mm to 40mm
• precast units are secured to precast posts
• joints shall be filled with mortar
• Concrete mix is M15 (1:2:4).
Cast in situ concrete partition wall Precast concrete slab partitions wall
• Thickness ranges from 80mm to 100mm
• It is poured monolithically with intermediate columns
• It is rigid and stable both in vertical and horizontal directions but
the framework is costly.
• The reinforcement consisting of mild steel bars or B R C fabric is
placed in the center of the wall thickness.
• Concrete mix usually adopted in the work is M15 (1:2:4).
CONCRETE PARTITION WALL
WALL PARTITIONS CONSTRUCTED FROM SPECIAL
PRECAST UNITS
•the wall is constructed from precast T-shaped or L-
shaped units
•light weight, hollow partitions can be built without the
need for vertical posts
•cement mortar mix proportion of 1:3 is used for jointing

9. GLASS PARTITION WALL
Hollow glass blocks
• Are made from sheet glass or hollow glass blocks.
• Provides good aesthetics and allow light
• Are damp, sound and heat proof.
• Easy to clean and maintain.
• Sheets of glass are fixed in the frame work of wooden or metal.
• Hollow blocks doesn’t need timber framework..
Sheet glass blocks

10. WOODEN PARTITION WALL
• Lighter in weight and easy to construct.
• Neither sound-proof nor fire-proof.
• Not suitable for damp locations.
Are of two types
Common partitions
Are comprised of vertical
members known as studs
bridged between upper
horizontal(head) and lower
horizontal(sill) member.
Trussed partitions Are designed
on the principle of truss are
useful where it is possible to
provide supports only.

11. PLASTER SLAB PARTITION WALL
•Plaster slabs or plaster boards are made from burnt gypsum or plaster of paris, mixed with sawdust or other fibrous material to reduce its weight
•Units of plaster slab prepared in an iron or timber mould with size 1 to 2m long, 30cm high and 50 to 100mm thick.
•they are equipped with suitable grooves to create rigid joints
•Plaster slab surface may be smooth or rough.

12. METAL LATH PARTITION WALL
• Metal lath partition wall are thin, strong, durable and considerably fire resistant.
• Metal lath partition walls are constructed by placing 2cm or 2.5cm channels vertically (called studs) and fixing metal lath to it on one side.
• Plaster is applied to both the sides of the metal
• If hallow partition is required, metal lath is fixed to the channels on both the sides and then plaster is applied.

13. A.C OR G.I SHEET PARTITION WALL
• Light in weight, impervious, durable, water tight and fire-proof.
• Asbestos cement sheets are made of asbestos cement sheets and fixed into timber
framework.
• Sheets are placed in position and joined by cement mortar.
• Are mostly adopted in works of temporary character.

14. CLASSIFICATION OF PARTITION WALL
There are three types of
partitions:
Sliding: Sliding partitions
consists of series of panels
that slide in tracks fixed to the
floor and ceiling. The machine
if the partition is similar to
those of sliding doors.
Sliding & folding: Sliding and
folding partitions operate in a
similar manner to sliding
folding doors. They are
normally used for smaller
spans.
Screens: Screens are usually
constructed of a metal or
timber frame. It is fixed with
plywood and chipboard
inside. The screen supported
with legs for free standing
and easy movement.
