properly secure bolts on jack beams
After setting the last jack beam into
place tighten all 3/4” bolts that
connect the jack beams to the main
trusses. The 1/2” bolts which connect
jack beams with each other are tightened
differently. Tighten the first nut down
far enough to make a good connection
but not far enough to restrict movement.
The second nut is used as a locknut. This
is important so that the connection is
allowed to move as the bin is loaded.

intermediate purlins connect to sidewall
Between each 2 trusses, bolt the purlin
mounting angles to each of the three
locations provided on the 10 gage sidewall
sheets (fig. b). Be sure that the sidewall
sheet is orientated correctly so that the
flashing holes are above the mounting
angle holes. Bolt two 14’ intermediate
purlins and one 16’ intermediate purlin to
these brackets while also resting them on
the jack beams (fig. c and d, page 31).
Place the 1 1/2” x 5” spacers between
purlins and mounting angles.
