Lintel

• WHAT IS A LINTEL ? A LINTEL is a sort of beam which is equal to the width of the wall , and the ends of which are built into the wall. Lintel acts like beam and transfers the load

vertically to the supporting walls. The ends of the lintel are built into the

masonry so as to convey the weight carried by them to

the masonry in the jambs.

• VARIOUS TYPES OF LINTELS -1) TIMBER LINTELS.2) STONE LINTELS.3) BRICK LINTELS.4) STEEL LINTELS.5) REINFORCED CONCRETE LINTELS.

TIMBER LINTELS-

• Hard timber, like teak is used for this type of lintel.•These lintels are mostly used in the hilly areas.•The ends of the timber lintel rest on the mortar base on the walls for a minimum width of 15 cm.•Timber lintels are the oldest types of lintels, though they are not commonly used now a days because they are relatively costlier, structurally weak and vulnerable to fire.

STONE LINTELS -

•A stone lintel consists of a simple stone slab of greater thickness. •These are used where stones are abundantly available. •They can also provided over openings in brick walls. •It consists of simple atone slab of greater thickness. •Dressed stone give architectural appearance. •These lintels are used in stone masonry structure of buildings.

BRICK LINTELS-

•Bricks lintels are built from well burnt and copper coloured bricks. •They are not structurally strong.• They are not for small openings, generally not

exceeding 1 metre span. •They are used for light loads.• Arched bricks lintel imparts more thrust.

STEEL LINTELS-

•Steel lintels are provided where the opening is large and where the super-imposed loads are also heavy. •It consists of rolled steel joists or channel sections either used singly or in combination of two or three units.•Steel lintel consists of rolled steel joints (RSJ) or channel section. •Steel Lintels are mostly used or super structures.

REINFORCED CONCRETE LINTELS-(R.C.C. LINTEL)

• Reinforced cement concrete lintels have replaced practically all other types of lintels because of their strength, rigidity, fire resistance, economy and ease in construction.

• They can be used on any span.
