9. Measure between rafter peaks, verify that the
on-center
dimension
is forty-eight inches (48"), and tighten pipe
strap Tek screws on second rafter.
FRAME ASSEMBLY (continued)
NOTE:
Do not
secure the purlin pipe to the pipe strap
on the second rafter at this time.
10. Repeat Steps 5-9 to install the first section of purlin
pipe for the remaining purlins for the first two rafters.
11. Choose another rafter assembly and set it in position.
12. Using Tek screws, secure the leg tubes of the
third rafter to the 105088 connectors as previously
described.
13. Take a 75" section of purlin pipe (131S075), slide it
through a pipe strap of the rafter, and place the plain
end of the pipe over the tapered end of the installed
purlin pipe of the first rafters.
14. Verify that the distance between the rafters is 48"
center-to-center. Adjust the rafter forward or backward
as needed to maintain this dimension.
15. Tighten pipe strap Tek screws to secure pipe to rafter.
16. Add purlin pipes to complete purlin runs between
second and third rafters.
17. Repeat the above steps as needed to stand, place, and
secure remaining rafters and purlins to complete the
frame assembly.
Each purlin run is completed using a single plain pipe
that is shorter than the 75" swaged pipes used up to
this point. (These plain pipes do not include a tapered
or swaged end.)
Consult the Side Profile diagram in the Quick Start
section
for your building
to identify the plain pipe at the
end of each purlin run.
If the last rafter is plumb and the purlin pipe extends
beyond the end of the rafter, cut the last section of
purlin pipe to the required length if needed.
ATTENTION:
Typically purlin pipes do not need cut.
Verify that you have selected the correct pipe to end
the purlin run before cutting the pipe to length. Consult
the Side Profile diagram for additional details.
Do not allow the purlin to extend beyond the end rafter.
See earlier diagram (Step 7).
18. Once all rafters are set and all purlins are in place
and secured, return to each pipe strap and drive a Tek
screw
through the pipe strap and into the purlin
. Refer
to the diagram in Step 7 if needed.
19. After securing all purlin pipes to each pipe strap, locate
all purlin pipe joints and secure each of these using a
Tek screw.
20. Remove the temporary bracing (if needed) and
complete the next steps to square and anchor the
frame.
