Procedure 4-5.
1.
Ensure that Procedure 4-3, "Create Cable and Anchor Holes for Raised
Floors," on page 4-5 has already been performed.
2.
Perform the following substeps for each hole associated with each frame to be
installed on the raised floor:
NOTE: The threaded rod must be absolutely perpendicular to the floor.
Using a level is recommended.
a.
Insert the threaded rod into the anchor holes in the tiles, making sure that
the threaded rod is perpendicular to the hole.
b.
Strike the top of the threaded rod with a hammer using enough force to
mark the concrete floor.
3.
Remove the floor tiles for access to the concrete floor.
4.
Use a HEPA vacuum cleaner to collect the dust while drilling. Drill an 18 mm
diameter hole in the concrete floor to a depth of 3 inches (7.7 cm).
NOTE: If the hole is drilled at an angle the anchor and frame will not
come together properly.
5.
Ensure that each hole is clean after the drilling is complete.
6.
For each threaded rod, thread the following components in the order shown
onto one end of the rod (these components are threaded on the rod while the
rod is upside down; see Figure 4-4 on page 4-10 to identify the components
and their orientation):
a.
Torque nut
b.
Small steel washer
c.
Metal sleeve
d.
Nylon collar
e.
Expansion sleeve
f.
Cone nut (thread onto the rod until the end of the threaded rod is flush
with the bottom of the cone nut)
NOTE: These components should be in contact with each other, but do
not tighten the assembly because doing so could prematurely expand the
expansion sleeve.
