FRAME ASSEMBLY (CONTINUED)
The first purlin and the first two rafters should appear
as shown:
10. Move down the rafters to the first rafter joint and place
a cross-connector over the inside rafter at that joint.
11. Assemble the first two sections of the second purlin
and install it as you did the top/center purlin.
12. Position the cross-connector and the purlin over the
pipe joint of the rafter assembly and set the on-center
rafter spacing.
Remember:
To prevent damage to the main cover and
end panels, do not allow the purlin to extend beyond
the edge of the end rafter.
Cross Connector
13. Tighten the cross-connector and install a Tek screw as
shown to secure the purlin pipe joint and to secure the
purlin to the cross-connector.
14. Move to the other upper pipe joint on the inside rafter,
place a cross-connector over the joint, and repeat
the steps to install the first two sections of the last
overhead purlin.
NOTE:
Position the cross-connector and purlin on the
rafter pipe joint. Do not remove the temporary bracing
until additional rafters are in place.
To this point, the assembled frame includes two rafters
and three top purlins as shown.
15. After attaching the last overhead purlin to the inside
rafter, move down the rafter assembly to the pipe joint
below the bottom chord and place a cross-connector
(#102546) over the rafter pipe.
This inserts shows the purlin, clamp and cross-
connector as seen from the inside of the building.
