Difficulty: Easy
Correct Answer: queen closer
Explanation:
Introduction / Context:
Bonding in brick masonry requires occasional use of specially cut bricks known as closers. These ensure that vertical joints are staggered properly, especially at corners (quoins), to achieve structural integrity and aesthetic regularity. This question checks recognition of the correct closer produced by cutting a brick along the centre of its width while retaining the full length.
Given Data / Assumptions:
Concept / Approach:
When a brick is cut longitudinally into two equal halves, the product is called a queen closer. Its dimensions become approximately L × (W/2) × H, where L is unchanged. Queen closers are typically placed next to quoin headers in English bond to avoid continuous vertical joints. This distinguishes them from king closers (which taper) and other special cuts used for specific bonding patterns.
Step-by-Step Solution:
Verification / Alternative check:
Standard bonding diagrams in textbooks show queen closers immediately adjacent to quoin headers, providing the necessary break in vertical joints through successive courses.
Why Other Options Are Wrong:
Common Pitfalls:
Confusing “half brick” (half length) with “queen closer” (half width); mixing up king and queen closer shapes.
Final Answer:
queen closer
