About this task
To ensure that you meet all site requirements, obtain the service of a qualified
consultant or structural engineer to help you prepare the floor.
Figure 24 provides an illustration of the earthquake resistance kit (
▌1▐
) after the
IBM service representative installs it on the nonraised floor.
Before the IBM service representative installs the kit, you must prepare the area
that is shown as
▌2▐
in Figure 24. This figure shows two of the most common
fasteners that you can use.
Use the following steps to prepare your nonraised floor:
Procedure
1. Obtain eight fastener sets for each frame that uses the earthquake resistance kit.
These fastener sets are used to secure the earthquake resistance kit load plate.
The type of fastener set that you use can be determined by your consultant or
structural engineer. However, each bolt or stud must meet the following
specifications:
v Each fastener set must withstand a 2400-pound pull force.
v The fasteners must have a dimension that fits into the load plate holes,
which are each 21 mm (0.826 in.) in diameter.
v The fasteners must be long enough to extend through and securely fasten a
load plate that is 3.0 cm (1.2 in.) thick. The fasteners must also be short
enough so that the height of the installed fastener does not exceed 6.5 cm
(2.5 in.). This maximum height ensures that the fastener can fit under the
frame.
The following examples provide descriptions of nonraised floor fastener sets.
Figure 24 illustrates the fastener sets.
