Locations For Fastener Installation - IBM DS8800 Introduction And Planning Manual

enough so that the height of the installed fastener does not exceed 65 mm
(2.5 in.). This maximum height ensures that the fastener can fit under the
rack.
The following examples provide descriptions of nonraised floor fastener sets:
v Threaded hole insert that is secured into the concrete floor and a bolt (with a
washer) that screws into the insert
v Threaded stud that is secured into the concrete floor with a nut (with a
washer) that screws over it
Figure 26 on page 158 shows illustrations of the example fastener sets.
2. Work with your consultant or structural engineer and use the following
guidelines to install the fasteners in the concrete floor:
v Use Figure 27 to determine the placement of the fasteners.
v Ensure that the installed fasteners do not exceed a height of 65 mm (2.5 in.)
from the floor. This maximum height ensures that the fastener can fit under
the rack.
v Ensure that the installation allows the fasteners to meet the required pull
force after they are installed (2400 lb pull force).
v If you use a threaded bolt that secures into a threaded insert in the floor and
the bolt extends longer than 30 mm (1.2 in.), which is the thickness of the
load plate, consider using a jam nut and a washer on the shaft of the bolt so
that the load plate can be secured snugly to the floor. Talk to your consultant
or structural engineer to determine whether a jam nut is necessary.
