PARTITION WALL

Prageeja.K

Partition walls

Load bearing or non load bearing.Load bearing wall is called an internal wallRequirements :

Strong-to carry its own load Resist impact Stable and strong to support wall fixtures. Thin and light Sound barrier Fire resistant

Types of partition walls

Timber partitionsMetal partitionsBrick partitionsClay block partitionsConcrete partitionsGlass partitionsAsbestos sheet or GI sheet partitionsMetal lath

Timber partitions

wooden framework either supported on the floor below or by side walls.

The framework consists of a rigid arrangement of timber members which may be plastered or covered with boarding etc from both the sides.

not fire-resistant

Brick partitions

Plain brick partitionsReinforced brick partitionsBrick nogging partitions

Plain brick partitions:Half brick thick

stretcher bond Wall plastered on both side Strong and fire resistant.

Reinforced brick partitions:Stronger To carry more loadsMeshed reinforcement – bricktor provided at

every third course.

Brick Nogging partitions:brickwork built within a framework of

wooden members.vertical posts called studs spaced at 60 cm to

150 cm apart .The nogging pieces are housed into the studs

at 60 cm to 90cm apart vertically.10cm thick partition wall, the studs and

nogging should be 15 cm wide so that after the brickwork is plastered from both the faces

Clay block partition walls

Hollow blocks moulded from clay, terracotta .

walls are light, rigid, economical, strong and fire resistant.

Thickness :6 cm to 15 cm

Concrete partitions:

cast in situ or built from panels or blocks, precast wall.

cast in situ walls, 10 cm thick and below, the reinforcement consisting of mild steel bars placed in the centre of the wall thickness.

Concrete mix 1:2:4

Precast concrete partition walls:

The slabs are 32 mm thick and are inserted in the grooves of the precast post and the joints are subsequently filled with mortar.

Glass partitions: Glass sheets or hollow blocks

Glass sheets:Wooden frame work –

glass sheets are fixed into it.

Timber beading.Light weight, sound

proof and damp proof.

Glass partitions: hollow block

Translucent units of glass.Sqaure:14cmx14cm or

19cm x19cmThickness 10cm.reduce thermal and sound

transmission.glass block are not used as

load-bearing walls.Laid in cement lime mortar

(1:1:4).

Anchors and vinyl stack material for wall assembly.

lock walls are tied into surrounding wall(s) using panel anchors or vinyl stack anchors every 3rd course

Asbestos sheet or GI sheet Partitions

These walls are economical, light and fairly rigid if constructed properly.

Fixed to frame of wood or steel.

Each slab consists of core or corrugated asbestos cement sheet(5mm) with the plain asbestos cement sheet (10mm) attached to it on either side.

Metal lath and plaster partitions

thin, strong, durable and is considerably fire resistant.

requires a framework of steel or timber for the purpose of fixing it in position.

lath is generally tied by galvanized iron wire to mild steel bars or channels spaced 15 to 30 cm apart.

Plastered on both sides

Metal lath and plaster partitions

improved insulation against heat and sound.

metal lath and plaster partition walls-cavity.

metal lath on both sides of specially shaped steel channels spaced at 30 to 45 cm apart.

channels are generally 3 to 10cm deep.

Steel Partitions

Studs (6.25 cm to 9cm)“C” shaped channels installed vertically, usually 40cm.

Steel track :“U” (6.25 to 9cm)shaped channels installed toceilings and floor to hold studs.

securing to ceiling joists with1 1/4” drywall screws. Install track at floor

framing door & window openings

Install drywall wall panels

Typically start at a corner or intersection.Avoid joints on both sides of the same stud.Secure panels to studs with drywall screws
