Red Seal Bricklayer Practice Exam

What is the function of lintels in brick construction?

1. To provide insulation

2. To support the weight above openings like doors and windows

3. To enhance aesthetic appeal

4. To join different types of bricks

The correct answer is: To support the weight above openings like doors and windows

Lintels play a critical role in brick construction by ensuring structural integrity around openings such as doors and windows. Their primary function is to distribute loads from the structure above the opening down to the walls on either side. This prevents any potential sagging or failure of the brickwork around vulnerable areas, which might otherwise experience stress due to the weight of the brick or other elements above. While other features may contribute to a building's insulation, aesthetic appeal, or the mixing of various types of bricks, lintels are specifically designed to carry and redirect loads. As a result, their importance cannot be overstated in maintaining the stability and safety of a structure, particularly in load-bearing walls. This load distribution is essential in preventing cracks or other structural issues that can arise from neglecting proper support above openings.
