2. Lintels -introduction
• A lintel is one type of beam which used to
support the above wall when openings
like doors, windows etc. are necessary to
provide a building structure.
• It is used to take loads coming from above wall
and transfer its load to the side walls.
• The lintel beam generally ends into the
masonry wall so as to convey the weight carried
by them to the masonry walls and its width is
same to the wall width.

4. function of lintel beams
• It supports the walls above the openings like doors,
windows etc.
• It provide a safeguard of the windows and doors.
• It withstands the imposed loads coming from
above bricks or block including the roofing
members.
• It is used to transfer all imposed loads to the side
walls.
• Sometimes they are used as decorative
architecture element.

5. Types of Lintel
According to the materials of their construction:
1. Timber Lintel
• Timber lintels are mainly used in the hilly areas
where timbers are available.
• Without proper ventilation, timber is liable to
decay.
• It is less durable.
• Timber being combustible it is vulnerable to fire.

7. 2. Stone Lintel
• This type of lintel is mainly used in this area
where the stone is abundantly available.
• Its use is mainly confined to stone masonry
structures.
Disadvantages
• Its high cost
• It can’t withstand excessive transverse stress.

9. 3. Reinforced Concrete Lintel
• They are used when the lintel span is smaller.
• They are very common in use because of their
durability, rigidity, strength, and fire resisting
properties.
advantage
• They are suitable for heavy loads and larger
span.
• economical and easy in construction.
• They can be either pre-cast or cast-in-situ.

10. 4. Brick Lintels
• Brick lintels are constructed with hard, well
burnt first class brick.
• It can be formed as bricks on end, bricks on
edge and coursed bricks laid horizontally over
openings.
• This type of lintel is used when the opening is
small (less than 1m) with light loadings
condition.
• Bricks with frogs filled with mortar give more
shear resistance at end joints than the normal
bricks.

11. 5. Reinforced Brick Lintels
• It provide more support than the brick lintels.
• The depth of the reinforced brick lintels is equal to
10 cm. or multiple of 10 cm (or one brick
thickness).
• The arrangement of the bricks should be such as
that there is enough space in lengthwise between
the adjacent bricks for the insertion of mild steel
bars as reinforcement.
• After insertion bars, the remaining gap is filled
with 1:3 cement mortar.
• 6 mm bars are used as vertical stirrups at every
3rd vertical joints.

12. 6.Steel Lintels
• They are suitable when the superimposed loads
are heavy and the opening gaps are large.
• These lintels consist of channel sections or rolled
steel joists.
• Depending upon the requirements, the lintel can
be a single section or combinations of two or
more.
• Single steel joist is either embedded in concrete
or cladded with stone facing to keep the same
width as the wall.
• Combination of two or more units are placed side
by side and held in position by tube separator.
