Download Solution PDFExplanation:
In stone masonry, the perpend refers to the vertical joint between two adjacent stones in the same course.
When these vertical joints align exactly above one another in alternate courses, it forms what is known as a perpend joint.
Key Characteristics of a Perpend:
-
It is a vertical mortar joint.
-
Should ideally be broken or staggered in successive courses to enhance bond strength and stability.
-
Proper placement avoids continuous vertical joints, which would otherwise weaken the structure.
Additional Information
-
Quoin joint: Related to the cornerstones or angle stones of masonry, not specifically a vertical joint.
-
Riser: Typically refers to the vertical face of a stair step, unrelated to masonry joints.
-
Bed joint: The horizontal joint between courses of stones or bricks.
