Product Overview
PAI28 Purlin Anchor
Purlin anchors offer solutions for wood-to-concrete and concrete-block connections which satisfy code requirements. The dual-embedment line allows installation in concrete or concrete block.
Material:
PAI — 12 gauge; MPAI — 14 gauge
Finish:
Galvanized (G90)
Installation:
Use all specified fasteners; some models have extra fastener holes. See General Notes.
Purlin anchor must hook around rebar.
Allowable loads are for a horizontal installation into the side of a concrete or masonry wall.
Strap may be bent one full cycle. (Bent vertical 90° then bent horizontal.)
Edge Distance — minimum concrete edge distance is 5". Minimum concrete block left-to-right edge distance is 20".
Concrete Block Wall — the minimum wall specifications are:
A — one # 4 vertical rebar, 32" long, 16" each side of anchor B — two courses of grout-filled block above and below the anchor (no cold joints allowed) C — a horizontal bond beam with two #4 rebars, 40" long, a maximum of two courses above or below the anchor D — minimum masonry compressive strength, f'm = 1,500 psi
Options:
See LTT and HTT tension ties for alternate retrofit solutions.
