Construction Test 6

Question 1

______ are the protrusions on a door or window frame's head or sill.

Accepted Answer

Horns

Answer

Horns are the extensions of the head or sill of a door or window frame that project beyond the jambs. These protrusions are typically left on the frame during manufacturing to provide a secure grip and facilitate proper fixing into the wall opening. They are often trimmed flush with the wall after the frame has been securely installed.

Question 2

_______ is the point at which the surfaces of a sloping roof intersect and produce an exterior angle greater than 180 degrees.

Accepted Answer

Hip

Answer

A hip is the external angle formed by the intersection of two sloping roof surfaces that meet at an angle greater than 180 degrees. It runs from the ridge (the highest horizontal line) down to the eaves. In contrast, a valley forms an internal angle, and a ridge is the horizontal line at the apex of a roof.

Question 3

With a _________, foundation excavation depth is often measured.

Accepted Answer

Boning rod

Answer

A boning rod is a T-shaped tool used in conjunction with sight rails to accurately establish and check the correct depth and level of excavations, particularly for foundations and trenches. It allows construction workers to precisely transfer levels from known reference points, ensuring the excavation is dug to the required depth and gradient.

Question 4

_______ is the main component in granite that gives stone its strength.

Accepted Answer

Quartz

Answer

Quartz is the main component in granite that imparts significant strength and durability to the stone. As a very hard and crystalline mineral, quartz contributes to granite's high compressive strength, resistance to abrasion, and overall robustness, making it a highly valued material in construction.

Question 5

_______ is the practice of using screeds to level a floor to a real level surface.

Accepted Answer

Screeding

Answer

Screeding is the practice of leveling a freshly laid concrete or mortar surface, typically a floor, using a long, straight edge known as a screed board or screed bar. This process ensures that the surface achieves the desired flatness and levelness, creating a smooth and even base for subsequent floor finishes.
