eRecTInG colUMn anD beaM enDWalls
Column and beam endwalls of 50 feet or less in span may be raised into position and set on
the anchor bolts as a unit . All rafters, column, girts (except outside endwall girts which connect
to the sidewall girts), door headers, door jambs, clips, diagonal brace rods, etc . should be
assembled on the ground with the bolts left finger tight . A spreader bar should be used to raise
the endwall frame . Because of the flexibility of the column and beam frames, care must be taken
in locating the points of attachment of the cables, and in raising the frame, to avoid bending
about the minor axis .
For spans of 60 feet and greater, the columns are usually erected first and then capped with the
endwall rafter . The girts, headers, jambs and diagonal brace rods are then added between the
end columns . During this erection process, the frame must be properly braced or guyed before
the lifting lines are disengaged . Final bolt tightening should be done once the frame is plumb
and square .
