Column Installation
Figure 5C
Remove filler sheets and install threshold weldments. Threshold weldments will either be anchored to the concrete or field welded to a tunnel beam. Do not anchor or field weld threshold weldments until door assembly is completed. Set right and left column weldments on threshold weldments and attach to the sidewall with 3/8" x 1" bin bolts. (Bolts size may vary slightly with sidewall thickness.) The sidewall will be on the outside of the column weldment.
Bolt head with sealing washer will be on the outside of this connection. Use flat washer on the inside of this connection. All of the sidewall bolts may be installed at this time but do not tighten until the door assembly has been completed. Use the provided measurements to assure that the columns are in the correct position and that the header beam will slide in place.
