What is the metal brace on an HRT boiler used to attach a wall to the steel framework that supports the wall called?

• A. Tie Rod
• B. Lintel
• C. Bracing
• D. Buckstay

Answer: (D)

In an HRT boiler, the metal brace that ties the wall to the steel framework and keeps the wall properly aligned and supported is called a buckstay. This member acts as a sturdy restraint, holding the wall in place and transferring loads into the boiler’s structural frame so the wall doesn’t bow or shift under thermal expansion, pressure, or construction loads.

A tie rod is a general tension member and isn’t specifically used to attach a wall to the boiler’s framework. A lintel is a horizontal support above openings in masonry, not part of boiler framing. Bracing is a broad term, but in this boiler context the precise name for that wall-attaching brace is buckstay.
