PA/HPA Purlin Anchors

PA/HPA purlin anchors offer solutions for wood to concrete and concrete block connections which satisfy code requirements. The PA's dual embedment line allows installation in concrete or concrete block.

Material: PA – 12 gauge; HPA – 10 gauge.

Finish: Galvanized. PA’s available HDG or ZMAX® coating .

Installation:

• Minimum concrete strength is 2000 psi.

•Use all specified fasteners; some models have extra fastener holes.

See General Notes.

•Purlin Anchor must hook around rebar.

•Wood splitting may occur when anchor is nailed to wood less than 3 1/2" wide. For widths less than 3 1/2", see PAI Holdowns for alternate nailing configurations.

Edge Distance: Minimum concrete edge distance is 5". Minimum concrete block left-to-right edge distance is 20".

Concrete Block Walls: 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 = 1500 psi.

Options: See LTT and HTT Tension Ties for alternate retrofit solutions.

ASCE7-05 12.11.2.2.5 states: .. Diaphragm to structural anchorage using embedded straps shall have the straps attached to or hooked around the reinforcing steel, or otherwise terminated to effectively transfer forces to the reinforcing steel.
