STEP 9
(Anchoring: Optional)
Proceed to Step 10 if not anchoring.
1.
Concrete shall have compression strength of at least 3,000 PSI and a minimum thickness of 4"
in order to achieve a minimum anchor embedment of 3¼". NOTE: When using (¾" x 5½") long
anchors; if the top of the anchor exceeds 2¼" above the floor grade, you DO NOT have enough
embedment.
2.
Maintain a 6" minimum distance from any slab edge or seam. Hole to hole spacing should be a
minimum 6½" in any direction. Hole depth should be a minimum of 4".
3.
Shim each column base as required until each column is plumb. If one column has to be elevated
to match the plane of the other column, full size base shim plates should be used. Shim thickness
MUST NOT exceed ½" when using the 5½" long anchors with the lift. Adjust the column
extensions plumb.
4.
Before proceeding, double check the measurements and make certain that the bases of each
Column are square and aligned with the chalk line. Raise the lift up and down and make sure it
operates properly at the locations prescribed by the markings on the floor .
5.
Using the base plate on each column as a guide, drill each anchor hole approximately 4½"
deep using a rotary hammer drill and ¾"
concrete bit.
6. After drilling, remove dust thoroughly from each hole using compressed air and / or bristle brush.
Make certain that the columns remain aligned with the chalk line.
7.
Assemble the Washers and Nuts on the anchors then tap each hole with a hammer until the
washer rests against base plate. Be sure that if shimming is required, enough threads are left
exposed. (see fig. 11)
8.
After any necessary shims are installed, tighten each nut 3-5 turns past hand tight. IMPORTANT
If anchor bolts do not hold when torqued to required amount, concrete must replaced. Saw cut
and remove 24" x 24" square area each column base then re-pour with reinforced 3,000 PSI
concrete to a depth of six inches minimum, keying new concrete under existing floor
. (See fig.
11,11.2 )
ALWAYS WEAR SAFETY GOGGLES!
