FRAME ASSEMBLY (CONTINUED)
ATTENTION:
The last rafter to place in position will
be the remaining end rafter. This end rafter includes
the pipe straps attached during the rafter assembly
procedures and is identical to the first end rafter set in
place.
22. Set the end rafter in place and align the purlins with the
pipe straps (previously attached to the rafter). Insert the
rafter feet mounting bolts (bolt head to the outside) and
tighten as previously instructed.
23. Begin with the top pipe strap and ensure that
approximately half an inch of the purlin extends through
the pipe strap and tightened the pipe strap mounting
bolts.
24. Verify that the end rafter is plumb.
NOTE:
If the rafter is not plumb (straight up and down)
and more of the purlin pipe needs to extend through
the pipe strap and beyond the edge of the rafter, it may
be necessary to cut the purlin to the required length.
To prevent cover damage,
do not allow the purlin to
extend beyond the edge of the rafter
.
25. With all rafters in place and the top five (5) purlins
installed and tightened, return to the rafter feet and
tighten the main bolt that attaches the bottom plate of
the rafter foot to the upper portion of the foot.
26. Complete the ATTACH THE BOTTOM and ATTACH
THE CHORD PURLIN procedures that follow.
ATTACH THE BOTTOM PURLINS
After the top five (5) runs of purlins are in place and secure,
complete these steps to install the remaining purlins.
Required tools:
• Tape measure
• Permanent marker
ATTENTION:
The bottom purlins run on the inside of the
rafter legs near the bottom of those rafter legs.
1. Begin at one end of the frame assembly and measure
up 13 1/2" from the rafter foot mounting plate on the
end rafter and make a mark on the inside of the rafter
leg.
NOTE:
This mark and the remaining marks identify the
location of the bottom purlin for each side.
The mark
identifies the center of the purlin
.
2. After marking the end rafter, attach a pipe strap to the
inside of the rafter leg so that the strap is positioned
with the mark at its center. Do not tighten the strap Tek
screws at this time.
3. Move to the remaining leg on the same rafter assembly
and mark as instructed in the previous steps.
4. Repeat Steps 1-3 for the remaining end rafter
assembly.
5. On the first inside rafter assembly, measure the same
distance (13-1/2") up the rafter leg from the foot base
and make a mark on the outside of the leg.
13-1/2"
