There are many types of partition walls used. Partition walls can be divided into brick partition, hollow block partition, glass partition, concrete partition, metal lath partition, asbestos sheet or G.I. sheet partition, plaster slab partition and timber partition walls based on the materials used for building the partition wall.
Building a Partition Wall
Among all the types, the most economical & commonly used partition wall is brick partition wall. So, we will discuss in this article on how to build a partition wall with brick.
Brick partition wall is cheap, so it is mostly used. Partition wall with bricks are of 3 types.
- Plain brick partition wall
- Reinforced brick partition wall
- Brick noggin partition wall.
1. Plain Brick Partition Wall: In this type of partition wall, the thickness of the wall is half of the thickness of brick. Bricks are used as stretcher to build the partition wall. Both the sides of the wall is plastered. If whole work is completed properly the partition wall will be comparatively strong and fire resistant.
2. Reinforced Brick Partition Wall: It is stronger than plain brick partition. This type of partition is used when the wall needs to carry external vertical loading. Thickness of the wall is equal to thickness of brick. Exmet is used as reinforcement. Special thin steel plates are cut and then made diamond shaped stretching by machine. It is known as expanded metal. Exmet is used at every 3rd coarse.
3. Brick Noggin Partition Wall: Brick noggin partition wall is built by brick masonry in a frame made by wood. Thickness of the wall is half of brick thickness. Wooden frame is built by the following members.
- Sill – Lowest horizontal member of wooden frame
- Head – Highest horizontal member of wooden frame
- Stud – Vertical member of wooden frame
- Noggin piece – Other horizontal members of wooden frame except sill and head.
Studs are placed vertically at 60 to 150 cm horizontal distance. Noggin pieces are placed horizontally after 60 to 90 cm vertical distances. Wooden frame work is used to reduce the effect of vibration and lateral load caused by opening or closing of doors and windows. Bricks are laid flat or side by side in the frame. For masonry, cement & aggregate is used in 1:3 ratio. If necessary, reinforcement can be used at every 3rd coarse of brick masonry work. Coal tar is used at the side of the wooden frame that is touched with the brick masonry. The width of noggin and stud is equal to the partition wall thickness. After masonry work is done, both the sides are plastered. The main problem with this type of partition wall is the woods used for noggin and stud can be damaged and after some days of the completion of masonry work, masonry can be detached from the wood member.
