FRAME ASSEMBLY
Use the diagrams and information that follows to assemble the main frame.
ATTENTION:
Rafters are heavy.
Always lift rafter from two separate points to prevent damage and injury.
Examine the site to determine the best way to move the rafters into position and to set them onto the ends of each set
of ground posts. Do not set rafters into position until the ground post concrete has set.
Optional, but recommended—especially for long buildings: Build a Rafter-Spacing Jig. (Customer supplies materials.)
A spacing jig saves time and helps to evenly space the rafters. Jig sets the on-center spacing of rafters. Examine the
photo below and use it to build a jig to space rafters during purlin installation. Use 2" x 4" lumber and wood fasteners.
Customer-supplied
rafter-spacing jig.
ATTENTION:
Anchor the first rafter in place using bracing, rope/cable, or a lift.
Do not allow the first rafter to stand
without bracing until additional rafters are set and purlins are installed
.
Connect rafters to ground posts using 105370B (1/2" x 4-1/2") bolts and FALB08B nuts.
Position nuts to the inside.
IMPORTANT:
Plumb the end rafter before
bracing it in place and installing other rafters.
ATTENTION:
Before adding
the nut to the 1/2" bolt, slide a
PGBRKAAS01 cable bracket onto
the bolt
at each end rafter
. Then
add the nut and tighten. See also
the details on the next page.
