A wall or division made up of bricks, studding, glass or other such material and provided for the purpose of dividing one room or portion of a room from another. Designed as non-load bearing walls. It may be of folding, collapsible or fixed type. Employed to provide privacy from consideration of sight or sound or both. A good partition wall should be cheap, light, thin, fire-resistant and easy in construction. If partition walls are load bearing then they are called as ‘internal wall’.
BRICK PARTITION WALL As the name suggests, this kind of partition wall is made up of bricks. There are three types- Plain Brick Partition Wall Reinforced Brick Partition Wall Brick Nogging Partition Wall
PLAIN BRICK PARITION WALL Half brick thick Stretcher bond Wall plastered on both sides Strong and fire resistant
CONSTRUCTION Step 1 : Arrangement Step 2 : Mixing of the mortar
Step 3 : Laying the bricks Step 4 : Selecting the joints
ADVANTAGES Economical (Raw material is easily available) Hard and durable Compressive strength is good enough for ordinary construction Different orientations and sizes give different surface textures Very low maintenance cost is required Demolishing of brick structures is very easy, less time consuming and hence economic Reusable and Recyclable Highly fire resistant Produces less environmental pollution during manufacturing process
DISADVANTAGES Time consuming construction Cannot be used in high seismic zones Since bricks absorb water easily, therefore, it causes fluorescence when not exposed to air Rough surfaces of bricks may cause mould growth if not properly cleaned Cleaning of brick surfaces is a hard job Colour of low quality brick changes when exposed to sun for a long period of time
REINFORCED BRICK PARTITION WALLS At every third or fourth course, the bricks are reinforced with iron straps 25 mm-28 mm wide and 16 mm thick. Mild steel bars of 6 mm diameter can also be used in case of iron straps. The thickness of wall is kept equal to half-brick. Can be of full floor height or restricted to 2000-2500 mm
FEATURES Reinforced brick masonry does not require shuttering and concrete Large cost saving compared with that of reinforced concrete. Cool rooms. Fireproof work. The tools and implements used are simple and low-tech. Weather protection.
BRICK NOGGING PARTITION WALL Consist of a framework of timber within which 1/2 brick partition are fitted. Framework of timber consists of head, sill, vertical members (studs), horizontal members ( noggings ), crossed braces and puncheons (studs over door frame). Studs (100x50 mm), head and sill (100x75 mm) The studs are placed at a distance of 3 to 4 times of brick length. The nogging pieces are placed at a vertical distance of about 600-900 mm. The crossed braces are provided at intersections.
The brickwork should be carried out in cement mortar of 1:3. To provide better stability a slight projection (50x25 mm) in the wooden studs and a corresponding groove in the adjoining bricks are provided.
This type of partition wall suffers from the drawback of the timber getting delayed. Moreover, the mortar used may not stick well to the timber members and thus the brickwork is likely to become loose after sometime. More durable and possesses strength than the other twos Can be of full floor height or can be restricted to 2000-2500 mm Serves as an efficient barrier
Types of wall finishes and materials Wood panelling It is a decorative treatment done with wooden panels on the walls in various designs. The material used can be plywood or wood covered with veneer or laminate . Cement plastered finish It is prepared in the form of mortar with cement, sand and water in proper proportions and applied on masonry manually to achieve a smooth finish or sand faced finish.
Laminate finish Laminate comes in various colours and designs. It comes in the form of sheet and is pasted with fevicol on Plywood. Tile cladding Different tiles, for example, granite, marble, glazed tiles or vitrified tiles are used for tile cladding. Tiles are available in a variety of colours and shapes. The selection of tiles depends on the place where it is to be applied i.e. interior facade or exterior facade.
Sand textured finish Sand Textured finish is used to give fine texture to the wall. This wall finish is not very commonly used because of its grains coming out. POP finish Plaster of Paris or simply plaster is a type of building material based on calcium sulphate hemihydrates. This is a smooth finish achieved by plaster of Paris generally applied on internal walls.
