8. The center column weldments (VTDL-0383) will be installed within the doorframe. The bottom of
the center column weldment will rest between the column outer cover strip on the threshold
weldment. The top of the center column weldment will bolt to the header beam weldment with
1" x 3-1/2" bolts. See details B and C
on Page 22 . Use VTDL-0338 shim plates between center
column and header beam and threshold weldment. Place one (1) shim plate on the threshold
weldment splice prior to the placement of the center column. The center column should be placed
inside of the tank with the base of the column near the threshold weldment splice. Tilt the column
upward into position and bolt it to the header beam. Install the top shim plate. The door panel
attachment plates of the column, header and threshold weldments should be aligned.
(See Page 22.) The center column is to be removed when door is opened; do not field weld to
center column. Do not tighten bolts until door panels are installed.
9. Verify that the doorframe is square and all door panel attachment plates are in alignment prior to
installing door panels.
10. Assemble door panels as shown on Page 23 . Door panels must be installed in this manner to
maintain proper orientation of hinges. Door hinge plate weldments (VTDL-0391) are to be placed
as shown
on Page 23 detail D. Use 3/8" x 1" bin bolts at door panel splices and 3/8" x 1-1/2" bolts
at hinge plate weldments. Bolt head with sealing washer should be on the outside for all splice
connections and on the inside for all hinge weldment connections. Follow installation details
on Page 24 for door panel placement. Use 1" x 2-1/2" Grade 8 bolts to attach door panels to the
doorframe. 1" x 3-1/2" Grade 8 bolts will be used at hinge location. Use only enough bolts to hold
panels in place and clamp the panels to the doorframe. Be sure that the panels are closed
completely and all holes are aligned. The door panels will be opened later to allow for field welding
and sealing. Caulk all along door panel splices.
11. Insert hinge pins (VTDL-0244) through hinge plates on the door panels and column weldments.
See detail E on Page 25 . Place 1/2" washer over top of the hinge pin and secure it with 1/8" cotter
pin (S-7241). Tighten all door panel bolts and doorframe connection bolts at this time.
12. Attach standard base stiffener weldments above header beam as shown on Page 25 . Use
3/8" x 1" bin bolts for attaching to seal strip and 3/8" x 2" bolts for attaching to sidewall plates.
Tighten all sidewall and stiffener bolts at this time. Shim as necessary and field weld stiffeners to
header beam. Base plates may have to be trimmed to align with header beam.
See Page 25 .
13. Anchor threshold weldments to foundation or field weld to tunnel beam. Field weld columns to
threshold weldments. Open door panels and field weld door panel attachment plates of header and
threshold to left and right column weldments. Be sure that the door panels open and close
smoothly. Field weld threshold weldment splice and access cover plates on column weldments.
Welding should be done on both the inside and outside of the doorframe.
Refer to Page 26 for
complete field welding details.
14. Clean, inspect, and paint all welds. Place foam seal strip all along the outer edge of the door panel
assembly to seal door panels. Close door panels and install all door panel bolts with washer on
each side. Tighten door panel bolts. Inspect all welds and door assembly bolts at this time. Place
decals DC-GBC-1A and DC-GBC-1S on the inside of the door panels. Caulk any gaps around the
center column weldment and threshold weldments.
