FRAME ASSEMBLY (CONTINUED)
10. Using the mark on the inside of the rafter leg as a
guide, slide the cross-connector (#102546) and purlin
so that the center of the purlin pipe is in line with the
mark on the rafter leg.
11. Tighten the bolts on the cross-connector to secure the
purlin.
12. Install a Tek screw (FA4484) through the cross-
connector and through the pipe joint of the purlin to
keep the joint tight.
13. Continue to assemble and attach the remainder of the
same bottom purlin until the entire purlin is secured to
the frame.
14. Repeat the above steps for the remaining bottom
purlin.
The frame with the purlins assembled to this point
should resemble the drawing below. There are seven
(7) purlins in the drawing. (See the arrows for location.)
Tek Screw
NOTE:
The FA4484 Tek screw is used throughout this
assembly.
ATTACH THE CENTER PURLIN
The center purlin is attached to the chord and runs
on top
of the chord
the length of the shelter. As before, regarding
all end rafter purlin connections
, the center purlin is
attached using a pipe strap. A cross-connector (#102548)
is used to secure the center purlin to the chord of the inside
rafters only.
Complete these steps:
1. Locate the center of the chord of the end rafter and
install a pipe strap at that location
on top of the chord
(if
not installed earlier).
Do not tighten at this time
.
2. Measuring from end-to-end on the chord, locate the
center of the chord on the inside rafter and mark the
location.
3. Position a cross-connector (#102548) over the chord
and assemble the first two sections of the remaining
purlin.
4. Insert the purlin through the pipe strap (#QH1070) on
the chord (end rafter) and through the cross-connector
on the chord of the inside rafter.
REMEMBER:
The center purlin runs
on top
of the
chord.
