Q.48 Which of the following is a purpose served by lintel?
- ATo support the wall above the openingCorrect
- BTo join the column at sill level
- CTo join the foundation
- DTo support the slab
Solution
Concept
A lintel is a horizontal member placed over a door or window opening to carry the load of the wall above.
Step-by-step solution
1. A lintel is placed just above a door, window or other opening. 2. It carries the masonry and load above the opening. 3. It transfers this load to the walls on both sides of the opening. 4. So the answer is (A).
Explanation
A lintel is a beam of RCC, stone, steel or timber placed over an opening. It supports the wall above the opening and sends the load to the side walls. Without a lintel, the masonry above the opening may crack or fall.
Why the other options are wrong
B: A member at sill level is a sill or sill band, not a lintel. C: The plinth beam or foundation joins at the foundation, not the lintel. D: The slab is supported by beams and walls, not by a lintel.
Shortcut
Lintel = beam over an opening.
Common mistake
Confusing a lintel (above the opening) with a sill (below the window).
Correct answer: A) To support the wall above the opening
