Which component is used to prop the frame at every lifting stage?

• A. Eave strut
• B. Door jamb, and door header
• C. End wall parts
• D. Brace rods

Answer: (A)

In frame erection, keeping the structure square and stable as sections are raised is essential. The eave strut is the temporary member that spans between columns at the roofline and acts as the prop at every lifting stage. It provides a rigid, level surface that transfers loads and anchors lifting equipment, helping to prevent sway and maintain proper alignment as each new section is added. Door jamb and door header relate to openings and aren’t used as universal props; end wall parts serve end sections rather than as ongoing lifting props; brace rods are used for bracing but aren’t the standard, consistent prop across all lift stages like the eave strut.
