An anchor bolt assembly consists of a bolt and washer
with a sleeve 2 times the diameter of the bolt. When
the assembly is cast in concrete, the washer prevents
the sleeve and bolt from being pulled. The sleeve I.D.
provides an adjustment allowance around the bolt. A
lug is generally welded on the bolt to prevent rotation
when tightening. Anchor bolts should be located in the
concrete by a template dimensioned from the pump
installation drawing. The top of the sleeve should be
temporarily sealed with waste material to prevent
concrete from entering during the concrete pouring
operation.
4. Installing Pump on Foundation If subbases or
floorplates were directly anchored to poured concrete
foundations, surface irregularities would cause
distortion. Rectangular metal blocks and shims, or
metal wedges having a small taper, are placed beside
each anchor bolt to level the subbase or floorplate, see
Fig.W2 and Fig.W3. The anchor bolts are then drawn
tight enough to maintain position and level.
To secure the shims in place and provide a level
surface for the base or plate, grout is poured over the
concrete foundation. A ¾” to 1-½” grout allowance is
recommended. When subbases have cavities, grout
holes are provided to fill all spaces. After the grout
has hardened, permanently tighten the anchor bolts.
When the grout has hardened and the anchor bolts are
permanently secured, recheck level.
NOTE: On large subbase/floorplates, shimming is
recommended to be at 24” spacing.
