ERECTION AND SAFETY MANUAL
4.7 ERECTING THE 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, columns, 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 fi nger
tight. A spreader bar should be used to raise the endwall frame. Because of the fl exibility 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 fi rst 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.
SPREADER BAR
NOTE:
Stay clear of all moving loads Make certain all framing is properly braced or guyed before lifting
lines are removed. Follow all OSHA regulations! Safety fi rst!
