7.6 Installation Of Column Extension (Ref. Fig. 9)
• Remove the column extension from
the package. Make sure to be careful
to avoid damaging the paint;
• Align the holes between the column
and the extension with carriage bolts
M10X20 and fl ange nuts M10;
• Tighten the bolts and nuts thoroughly.
7.7 Anchoring Columns
• Use the base plate on the column as a
guide and drill each hole in the
concrete with the rotary hammer drill 3/4in bit. Please refer to the anchor
bolt manufacture website for recommended values. To assure full holding
power, do not ream the hole or allow drill to wobble;
• After drilling, remove dust thoroughly from each hole using compressed air
and/or wire brush. Make certain that the column remains aligned with the
chalk line during this process;
• Assemble the
washers and nuts
on the anchors then
tap into each hole
with a hammer
until the washer
rests against the
base plate. Be sure
that if shimming
is required that
enough threads are
left exposed;
• If shimming is
required, insert the
shims as necessary
under the base
plate so that when
the anchor bolts
are tightened, the
columns will be
plumb;
