PA/HPA PURLIN ANCHORS
|
Wood-to-concrete and concrete block connectors that satisfy code
requirements. This line consists of single units, with no separate anchors required.
The PA'S Dual Embedment Line allows installation in concrete or
concrete block.
MATERIAL: CPAI --18 gauge x 3-3/4" ; MPAI --
14 gauge x 3-3/4" ; PA -- 12 gauge x 2-1/16"; HPA -- 10 gauge x 2-1/16".
FINISH: Galvanized. Some products 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.
- Wood splitting may occur when anchor is nailed to wood less than
3-1/2" wide. For widths less than 3-1/2", see PAHD Holdowns for alternate
nailing configurations, or PAI, CPAI.
- PA is a straight purlin anchor that attaches to the top of the
purlin.
- PAI is designed for wood I-joists. Nail spacing is for
10dx1-1/2" nails 3" on center, to minimize the chance of wood splitting. Maximum
ledger width for full loads is 1-1/2".
EDGE DISTANCE -- Minimum concrete edge distance is
5". Minimum concrete block left-to-right edge distance is 20".
CONCRETE BLOCK WALLS -- The masonry embedment line
on PA, PAI, PATM, MPAI allows for 4" of grout embedment in a standard 8"
concrete masonry unit. The minimum wall specifications are: one # 4 vertical rebar,
32" long, at 32" o.c.; two courses of block above and below the anchor; 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 3/8" aggregate grout. Grout shall
be vibrated per the 1997 UBC section 2104.6.2.
OPTIONS: See LTT and HTT Tension Ties.
CODES: ICBO 4945. BOCA, ICBO, SBCCI NER-393; Dade
County, FL 97-0325.03 (PA).

- Minimum penetration for 16d commons is 1-15/16".
- All bolt values assume a minimum lumber thickness of 2-1/2",
except the HPA which require a minimum lumber thickness of 3-1/2".
- 16d sinkers (9 gauge x 3-1/4") or 10d commons may be substituted
for the specified 16d commons at 0.85 of the table loads.
- Allowable loads have been increased 33% and 60% for earthquake or
wind loading with no further increase allowed; reduce for other load duration's according
to the code.
- The PATM is designed to be installed at a 2° angle. Less load will
be developed at steeper angles.
