What is Lintel?
A beam that is placed across the opening like doors, windows, etc. is known as Lintel.
It supports the loads above it. There are different types of lintel which are described below.
Its ends are built into the wall and its width is equal to the thickness of wall.
Bearings of Lintel
Its bearing should be equals to the height of the beam.
It should be equals to 10 CM. It should be 1/10th of the Span of the lintel.
Lintels are classified on the basis of a material of construction:
- Timber lintel
- Stone lintel
- Brick lintel
- Steel lintel
- R.C.C lintel
Types of lintel
1) Timber lintel
- Timber is used as a beam in lintels are known as Timber lintel
- It is mostly used from ancient time but nowadays it is replaced by some modern techniques.
- The main disadvantages of the timber lintel are more cost and less durable and vulnerable to fire.
- Sometimes, these are strengthened by the provision of mild steel plates.
2) Stone Lintel
- Stone is used as a beam in lintel are known as a stone lintel
- These are the most common types of lintel, especially where the stone is abundantly available.
- Its thickness is the most important factor.
- Its minimum depth should be 15 cm.
- Span is Up to 2 meters.
3) Brick Lintel
- Bricks lintel are used when the opening is less than 1 meter and lesser load is acting.
- Bricks with frogs are provided to give more shear resistance to the ends.
- It is also called a joggled brick lintel.
4) Steel Lintel
- These types of lintel are used when the superimposed loads are heavy and the opening is large.
- These are made up of channel sections or rolled steel joists.
- These are made up of channel section or in combinations according to the requirement.
5) RCC Lintel
- RCC lintels are made up of reinforced concrete
- It is widely used nowadays due to its strength, rigidity, fire resistance, economy, etc.
- It is easy to construct.
