27. With a level placed directly on the jack screw adjust anchor bolts
until the actuator screw is level with the mount. Tighten 1.25 inch
hardware. Torque anchor pin nuts to a minimum of 360 ft-lb (488
Nm) to maximum of 440 ft-lb (596 Nm).
2.4.8 Grouting Baseplate to Foundation, Models 8009A and 8009AE
Grout is used between the concrete foundation surface and the four base
plates to ensure a rigid, load-bearing connection between the mount and the
foundation. It is important that the grout manufacturer's instructions be
followed. These instructions are packaged with the grout.
For convenience, the essentials of the procedure are repeated as follows:
The grout must be 1.0-inch thick minimum at all locations (see Figure 2-23).
Verify that each anchor bolt nut will have no less than two threads above the
nut. The normal ambient temperature range for good "early-strength"
grouting is 55°F to 80°F (13°C to 27°C). When temperatures at the job site are
outside this range, the procedures given here must be modified to
compensate for the high or low temperature. If the temperature is outside the
range, perform one of the following procedures before proceeding to the
grouting procedure.
2.4.8.1 Hot Weather Grouting
Temperatures above 80°F (27°C) accelerate hardening of the grout, reducing
the time that the grout remains workable after mixing; therefore, it is
necessary that either procedures be used which permit placing of the grout
more quickly, or the available working time increased by cooling the mixture
and the mount base plates.
If the first approach is taken, it is suggested that grout be mixed for each base
plate separately and poured immediately. Mixing time could be reduced to
one minute by use of an electric drill and mixing blade made of steel rod.
If the second approach is taken, grout working time may be increased by use
of cold materials, cool foundation, and base plates. This approach involves
the use of cold or iced water in the mix to keep the as-mixed temperature of
the grout under 70°F (21°C), preferably between 50°F and 55°F (10°C and
13°C).
In either case, the following practices are recommended:
1. Store bags of grout in as cool a place as practicable, but at least in the
shade. Avoid exposing the bags to dampness or rain.
2. Give extra attention to saturating the concrete foundation for 24 hours
before grouting. Heat and wind cause rapid evaporation; therefore,
the concrete should be wet liberally and frequently to prevent drying.
