  1. 1. PRESENTATION<br /> ON <br /> LINTELS<br />
  2. 2. DISCUSSION INCLUDES :-<br />INTRODUCTION<br />DEFINATION OF LINTELS<br />VARIOUS TYPES OF LINTELS<br />CONCLUSION<br />
  3. 3. INTRODUCTION :-<br />Openings are invariably left in the wall for the provision of doors, windows, cupboards, almirahs, wardrobes, etc. And these openings are bridged by the provision of a lintel.<br />
  4. 4. WHAT IS A LINTEL ?<br />ALINTELis a sort of beam which is equal to the width of the wall , and the ends of which are built into the wall.<br />
  5. 5. VARIOUS TYPES OF LINTELS<br />1) TIMBER LINTELS<br />2) STONE LINTELS<br />3) BRICK LINTELS<br />4) STEEL LINTELS<br />5) REINFORCED CONCRETE LINTELS<br />
  6. 6. TIMBER LINTELS<br />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.<br />
  7. 7. A TIMBER LINTEL<br />
  8. 8.
  9. 9. STONE LINTELS<br />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.<br />
  10. 10. STONE LINTELS<br />
  11. 11. BRICK LINTELS<br /> Brick lintels are not structurally strong, and they are used where opening is less (less than 1 meter ) and loads are light.<br />
  12. 12. BRICK LINTELS<br />
  13. 13. STEEL LINTELS<br />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.<br />
  14. 14. STEEL LINTELS<br />
  15. 15.
  16. 16.
  17. 17. REINFORCED CONCRETE LINTELS<br /> 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.<br />
  18. 18. REINFORCED CONCRETE LINTELS<br />
  19. 19.
  20. 20. CONCLUSION<br />Thus a lintel is a sort of beam, the width of which is equal to the width of the wall, and the ends of which are built into the wall.<br />
