PNEG-1742 VTDL-48 - 8 x 9 Door Assembly
8. The center column weldment (VTDL-0541) will be installed within the door frame. 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 3/4" x 2-1/2" bolts.
See details B and C on
. Use VTDL-0403 shim plates between the center column and the
header beam and threshold weldment. Place one 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.
The center column is to be
removed when the door is opened. Do no field weld to the center column. Do not tighten bolts
until the door panels are installed.
9. Verify that the door frame is square and all door panel attachments plates are in alignment prior to
installing the door panels.
10. Assemble the door panels as shown on
. Door panels must be installed in this manner to
maintain proper orientation of the hinges. Door hinge plate weldments (VTDL-0402) are to be placed
as shown on
. Use 3/8" x 1-1/2" bin bolts at the door panel splices and 3/8" x 1-1/2" bolts at
hinge plate weldments. The bolt head with a sealing washer should be on the outside for all splice
connections and on the inside for all hinge weldment connections. Follow installation details on
for door panel placement. Use 1" x 3-1/2" grade 8 bolts to attach the door panels to the door
frame. Flat washers are to be used on both sides of all 1" bolt connections. Use only enough bolts to
hold panels in place and clamp the panels to the door frame. 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 D,
. Place a 1/2" washer over the top of the hinge pin and secure it with a
1/8" cotter pin (S-7241). Tighten all door panel bolts and door frame connection bolts at this time.
12. Attach standard base stiffener weldments above the header beam as shown on
. Use
1" x 3-1/2" bolts for attaching to the seal strip and sidewall plates. Tighten all sidewall and stiffener
bolts at this time. Shim as necessary and field weld stiffeners to the header beam. Base plates may
have to be trimmed to align with the header beam.
13. Anchor the threshold weldments to the foundation or either field weld to the tunnel beam. Then, field
weld the columns to the threshold weldments. Open the door panels and field weld the door panel
attachment plates of the header and threshold to the left and right column weldments. Be sure that
the door panels open and close smoothly. Field weld the threshold weldment splice and access cover
plates on the column weldments. Welding should be done on both the inside and outside of the door
frame. Refer to
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 the door panels and install all door panel bolts with a washer
on each side. Tighten the door panel bolts. Inspect all of the welds and door assembly bolts at
this time. Place the decals DC-GBC-1A and DC-GBC-1S on the inside of the door panels. Decals
DC-GBC-2A and DC-GBC-2S must be placed on the outside of the door panels. Caulk any gaps
around the center column weldment and threshold weldments.
