41 Anchors PA/HPA Purlin Anchors Wood-to-concrete and -concrete block connectors that satisfy code requirements. The PAs Dual Embedment Line allows installation in concrete or concrete block. MATERIAL: PA 12 gauge; HPA 10 gauge. FINISH: Galvanized. PAs available HDG or Z-MAX. 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 wide. For widths less than 3 ", see PAHD Holdowns for alternate nailing configurations, or PAI. EDGE DISTANCE Minimum concrete edge distance is 5". Minimum concrete block left-to-right edge distance is 20". CONCRETE BLOCK WALL The masonry embedment line on the PA allows for 4" of grout embedment in a standard 8" concrete masonry unit. 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. All cells grouted with 2000 psi aggregate grout. Grout shall be vibrated per the Code. Rebar quantities, sizes and lengths are minimum requirements and may be increased per any additional wall design requirements. OPTIONS: See LTT and HTT Tension Ties.

The UBC Section 1633.2.8 and IBC 1620.2.1 state: ... Diaphragm to wall 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. Available with additional corrosion protection. Check with factory. 1. Allowable loads are for a horizontal installation into the side of a concrete or masonry wall. 2. Minimum penetration for 16d commons is 1 ". 3. 16d sinkers (0.148" dia. x 3 long) or 10d commons may be substituted for the specified 16d commons at 0.85 of the table loads. 4. Allowable loads have been increased for earthquake or wind load durations with no further increase allowed; reduce where other load durations govern. 5. NAILS: 16d 0.162" dia. x 3 long.
