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.
Reinforced Brick Lintels. Heavy loadings and larger span length are the problems for brick lintels. These can be overcome by using the reinforcement bars. Reinforced brick lintels thus 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).
A lintel is a horizontal member which is placed across the openings like doors, windows etc. in buildings. Lintels takes the load from the structure above it and provides support. Lintel is also a type beam, the width of which is equal to the width of wall, and the ends of which are built into the wall.
Stone lintels are provided in the form of either one single piece or more than one piece. The depth of this type is kept equal to 10 cm / meter of span, with a minimum value of 15 cm. They are used up to spans of 2 meters. In the structure is subjected to vibratory loads, cracks are formed in the stone lintel because of its weak tensile nature. Hence caution is needed.
Timber lintel; Stone lintel; Reinforced concrete lintel; Brick lintel; Reinforced brick lintel; Steel lintel; Timber Lintel. Timber lintels are mainly used in the hilly areas where timbers are available. But in plain areas, uses of timber are limited because of the high cost. It also has other disadvantages. Without proper ventilation, timber is liable to decay.
