Frame Assembly
(continued)
With the first end rafter standing, plumb, and properly secured, set the interior rafters in place.
Stand the Interior Rafters
1. Stand the second rafter (Rafter B) and secure the rafter feet as before.
2. While the lift or personnel are holding the rafter in position, start at the top-center of the arch and
install a purlin. Each purlin pipe is attached using 3/8" x 1" Hex Cap bolts provided. Use two (2)
bolts per connection point when attaching the purlins to the purlin clamps. (See insert below.)
3. With center purlin in position (arrow below), install the remaining purlins. There are six (6) purlins
between each rafter. Consult the Frame Diagram shown earlier in these instructions for purlin
location.
4. Repeat the process for the remaining interior rafters for the length of your building. (Align the rafter
feet with the lines previously marked on the site if that method was used.)
5. After all interior rafters are in place and secure, install the final end rafter (Rafter A).
6. With all rafters in place, read the MUST READ document to anchor the frame.
You must anchor
the assembled frame before continuing.
7. After anchoring the frame, continue by installing the cabling for the structure.
ATTENTION:
As the purlins are attached, it may be necessary to tap the purlin brackets with a hammer to align the
brackets with same brackets on the next rafter set in place. To protect the cover, tape all rafter joints with duct tape.
Purlins (105118) are
interchangeable.
