What is a structural member placed against a furnace or wall to restrain motion of the wall called?

A structural member placed against a furnace or wall to restrain motion of the wall is known as a buckstay. This component is specifically designed to provide lateral support and stabilization, particularly in scenarios where walls are subjected to high temperatures or significant forces, such as within industrial furnaces or similar structures. Buckstays help to prevent wall movement or failure, ensuring the integrity of the overall structure. Their role is crucial in maintaining safety and functionality in engineering applications, particularly where thermal expansion or contraction could lead to structural issues.

Understanding the specific function of a buckstay helps in recognizing its importance in construction and engineering contexts, particularly in facilities that deal with heavy machinery or intense heat. While other terms like support beams or wall anchors may suggest some form of structural support, they refer to different applications and do not specifically address the need for restraining movement in high-stress environments like buckstays do.
