FRAME ASSEMBLY
Gather the parts:
• All rafter assemblies (Base plates are not shown.)
• Purlin pipe 1.315" x 75" swaged (131S075)
• Purlin pipe 1.315" x XX" plain pipe (#131P0XX)
• Band clamps (#QH1400) and cross connectors
(#102548)
• Struts (#QH1308) and Tek screws
NOTE:
The XX" represents the remaining length required
to reach the end of the shelter. Consult the Spec Sheet and
Side Profile diagrams (Quick Start) for pipe identification.
Frame Assembly Procedure
1. Stand one end rafter. The end rafters include the end
clamps. Be sure to position the bolt side of end clamp
to the inside of the frame
when setting the rafter in
position. See the diagram below.
NOTE:
Purlin pipe shown in the above diagram is
installed during the frame assembly.
2. Check that the rafter is standing straight (plumb) and
brace it in place.
4. Install the upper cross connector on the inside rafter
and insert the plain end of a purlin pipe through the
connector and through the upper end clamp at the top
of the end rafter. See circles above.
5. Verify that both rafters are plumb and properly spaced
on-center and tighten the upper clamps.
CAUTION:
To prevent cover damage, the ends of the
purlins should extend no more than ½'' past the end
clamp. See diagram that follows Step 1. Do not allow
purlin to extend beyond the edge of the end rafter.
3. Using the on-center, rafter-to-rafter spacing, set an
inside rafter in position. (Additional assistants are
required to hold the inside rafter in position.) See Side
Profile diagrams for the correct rafter spacing.
6. Move to the lower clamp positions and repeat Step 4
to install the purlin pipes in those locations. See the
diagram above.
7. Slide a band clamp (#QH1400) on each of the two
bottom purlins between the second and third rafters.
Position the head of each band clamp bolts toward the
outside of the shelter.
