Partitions are usually thin and light of construction. where the essential purpose is to serve as divisions.
Building a partition will not increase the actual floor area available within a house but by subdividing it more appropriately it can provide extra rooms which will make living in the house more enjoyable.
Whatever the purpose of the partition, a number of points need to be considered:
Lighting - natural daylight may not be necessary although it is often desirable. If an existing window is not going to be included in the partitioned off area, a new window could be added in an outside wall. Alternatively glazing could be incorporated into the partition to 'borrow' light from the adjacent room, this can easily be incorporated along the top of the partition.
Ventilation - although a window is probably the most common form of ventilation, it is quite possible to include an electrical extractor fan to ventilate the new area.
Electrics - often when a room is divided, it is necessary to change the ceiling lights. The existing light may need to be repositioned and a new light and switch may need to be added in the 'new' area..
Services -
Outlets may also be required on the partition for heaters, shower units etc.
Plumbing may also be required. The most obvious requirement is where the partition is being built to create a shown area.
Glass partitions:
Glass is very commonly used for partitions.
Usually used in offices, restaurants,workshops and also residences.
Many types of treatments are done on glass for it to loose its transparency.
Cause of which it can be used in bedrooms and bathrooms also.
Glass Blocks:
Now a days glass blocks are also used as partitions.
The standard size of one block is ,
7 ½” * 7 ½”
6 ½” * 6 ½”
They are usually joint by white cement.
One glass block cost around Rs 120 to Rs 130.
Rotating Glass Panels Used In A Partition:
Use of translucent panels which are fixed into stainless steel rods.
12 mm thick------rs.85/sq. ft
10 mm thick------rs 75
Glass block-120 to 130 rs
Adhesives used-
Araldite
Silicon
u.v. glow
Poloshing-
Crystal polish-rs10/running feet
Bewelling-rs 40 per running feet
Half round/full round-rs40 per running feet
Free standing metal room dividers:
These room dividers are fee standind i.e. assemblies not required.
Can be removed when not wanted.
Are portable.
Sound absorbing to some extent.
Full length aluminum hinges add strength and stability throughout the entire divider.
Room dividers can be locked together to form unlimited lengths.
Room Dividers will provide multiple and variable sized class or work areas without the limitations and costs of ceiling mounted track systems.
Room Dividers come in 6 heights ranging from 4' to 8'. The length of the divider depends on the number of panels you select. Available lengths are: 5'9" (3 panels), 9'-5" (5 panels), 13'-1" (7 panels), 16'-9" (9 panels), 20'-5" (11 panels), 24'-1" (13 panels).
Timber partitons :
Also known as stoolhings ,or stoothed ,stud or quarter partitions.
Consists of vertical members called studs or quarters.
2 main horizontal members known as head and sill.
Studs are stiffened by nogging pieces or noggings at vertical intervals of from 0.9 to 1.2 metre which are fitted more or less horizontally and tightly between the studs.
if provisions has to be made for a door the door posts should be sufficiently rigid to resist the impact of the door.
Plasterboard partitons:
Plaster board can be used to cover stud partition.
Consists of aerated gypsum encased in paper.
There are 4 types of plaster boards,
a) gypsum wallboard
b) gypsum lath
c) gypsum base board
d) gypsum plank
Available in plain and insulating grade.
Three types of joints which are used are:
Tapered edge
Square edge
Bevelled edge
Gypsum wallboard-
Ideally suited for direct decoration because the paper covering to one surface is smooth and ivory coloured.
Different sizes available: 2438mm x 1200mm
1829mm x 900mm
1219mm x 914mm
Available in two thicknesses 9.5 mm & 12.7 mm
It is secured by nails which has flat head and smooth shank.
b) Gypsum lath-
Narrow width plaster board.
Cheaper than wall board.
It has grey paper covering and characterised by rounded edges.
Sizes available: 406 mm x 1200 mm
406 mm x 1219 mm
406 mm x 1372 mm
Thk. 9.5 mm & 12.7 mm
Plastering required.
c) Gypsum base board-
Design for a plaster finish.
Square edged plaster board.
Sizes available: 914 mm x 1200 mm
914 mm x 1219 mm
914 mm x 1372 mm
Thk. 9.5 mm.
d) Gypsum plank-
19 mm thk. Plaster board.
Sizes available: 600 mm x (2350,2400,2700,3000) mm
Mainly used for encasement of steel columns and beams.
Aluminium frame partitions
The present concept of modular design in offices and commercial establishments has offered a wide scope of applications for use of aluminium extruded sections in door and partition.
The strength, low density, corrosion resistance and design flexibility of aluminium make it an ideal material for partitions.
The partitions can be so designed to have wooden panels at the bottom and glass on the top.
They can be built on site with very little disturbance to the masonry.
Being very light, these sections don’t add up much to the load on the structure.
WOOD-WOOL CEMENT PARTITIONS
The material consists of wood-wool (wood shavings) and ordinary cement.
Long shavings from 3 to 6 mm wide are coated with liquid cement, consolidated into slabs by means of a machine press, and then stored to mature.
The slabs are very light, can be easily fixed and sawn, and provide a good key to the plaster which is applied to the surfaces after fixing.
Their dimensions vary from 1800 to 4000 mm long by 600 mm wide by 50, 75 and 100 mm thick.
50 and 75 mm thick walls are more commonly used when the height does not exceed 2.4 to 3 m respectively for the cavity walls.
CLAY AND TERRA-COTA BRICK AND BLOCK PARTITIONS
THE COMMONEST TYPE OF CLAY PARTITION IS THE ORDINARY SOLID BRICK WALL OF 105mm {or 65mm IF LAID ON EDGE}
SUCH WALLS ARE RELATIVELY STRONG AND FIRE RESISTANT but THEIR WEIGHT PRECLUDES THEIR USE FOR PARTITIONS
HENCE CLAY BLOCKS WHICH ARE LIGHT ARE USED.
LIGHTNESS IS OBTAINED BY MAKING THEM HOLLOW.
Table giving the usual range of sizes in which clay blocks are made.
HEIGHT LIMITATION
62.5 WIDE BLOCK-HEIGHT SHOULD NOT EXCEED 3m
75 WIDE BLOCK-HEIGHT SHOULD NOT EXCEED 3.65m
100 WIDE BLOCK-HEIGHT SHOULD NOT EXCEED 6m
Height of one block corresponds to the height of three bricks plus two joints [{3*65}+{2*10}]
Blocks are built in cement mortar and are bonded in usual way with staggered vertical joints.
Advantages
Satisfactory mechanical strength, light, good heat insulation, fireproof, non-shrinkable and vermin proof.
Types of hollow clay blocks
A: smooth-faced block- faces being decorated as required
B: keyed block- deep sinking form a good key for plaster
C: rug face block- can be used for internal and external walls
D: six cavity load bearing block. Used as inner leaf of cavity wall
E: FIXING BLOCK.NAILS CAN BE DRIVEN DIRECTLY INTO THESE BLOCKS.
PRECAST CONCRETE BLOCK PARTITIONS
PRECAST CONCRETE BLOCKS ARE
-SOLID: FOR GENERAL BUILDING USE INCLUDING BELOW d.p.c LEVEL
-HOLLOW: FOR GENERAL BUILDING USE INCLUDING BELOW d.p.c LEVEL
CELLULAR: MAINLY FOR INTERNAL NON-LOADBEARING WALLS [i.e PARTITIONS]
THE BLOCKS ARE COMPOSED OF A BINDER WHICH IS USUALLY CEMENT, ALTHOUGH LIME IS ALSO USED, AND AGGREGATES LIKE NATURAL STONE, CRUSHED BRICK.etc
