About this detail

A structural tee section runs the full length of the curb to match the roof depth, utilizing standard weight sections or a built-up profile from 3/8-inch plates with full-depth 1/4-inch stiffener plates spaced at 4'-0" on center and within 3 inches of ends on each side of the web. The tee section is welded to the wide flange beam and stiffener plates using 1/4-inch fillet welds, with 2-12 intermittent welds and 6-inch continuous welds at each end. At corners, 4x4x1/4-inch angles measuring 3 inches long tie the assembly together, maintaining a maximum 1/2-inch clearance. Pre-fabricated curbs of minimum 14 gauge steel connect to the structural tee per architectural, mechanical, electrical, and plumbing drawings.
