Jack Arch is a structural element that is used to support a load-bearing wall or other structural element above an opening such as a window or door. It consists of a series of brick or stone segments arranged in a semi-circular or pointed arch shape, with each segment extending from a central support point. Jack arches are often used in construction to create openings in load-bearing walls without compromising the structural integrity of the wall. They are also used as decorative elements in architecture, as they can be designed in a variety of shapes and patterns to add visual interest to a building’s facade.
