Which masonry components are installed over openings in block walls to carry the load around the opening?

• A. Headers
• B. Lintels
• C. Corbels
• D. Trusses

Answer: (B)

Lintels are specifically designed masonry components that are placed above openings in block walls, such as doors and windows, to support the load from the wall above. The primary function of a lintel is to distribute the weight of the masonry above the opening evenly around the sides, ensuring that the wall's structural integrity is maintained. Unlike headers, which are typically associated with framing in wood construction and may not be relevant in block wall applications, lintels are essential in masonry because they provide the necessary support for horizontal spans. Corbels, while they serve decorative or supportive roles in architecture, do not function in the same way as lintels for load distribution over openings. Trusses, on the other hand, are used in roof systems and do not apply to openings in block walls. Understanding the role of a lintel is crucial for anyone in the construction field, particularly in masonry work, as it directly impacts both the safety and durability of the structure.
