3.3.1.6 Anchoring Equipment to Raised Floors
The anchoring of overhead and wall-mounted devices present a number of
considerations. Placement is very important; if equipment is bolted to a wall that
is on an aisle, the aisle may be unacceptably narrowed with the danger of injury
to personnel. Also, the serviceability of the equipment being mounted to adjacent
equipment may be inhibited.
Overhead applications generally include coax cabling, cable runways, and
mounts for earthquake bracing. All overhead applications should keep in mind
loading of overhead surfaces. Care must be exercised when deciding how much
can be held by the ceiling without some sort of building foundation support. In the
case of earthquake bracing equipment, cable runways can be secured overhead
then affixed to the equipment racks providing acceptable foundation support.
When anchoring cable runways to ceilings or walls, the manufacturer-supplied
support hardware shall be used.
Anchors used in overhead applications vary depending on the ceiling structure as
follows:
• For concrete and wood ceilings, the same principles discussed in floor
anchoring apply.
• For an exposed steel l-Beam ceiling, many cable runway manufacturers
make beam clamps for C-channel or threaded drop rods.
• For corrugated steel ceilings, C-channel tracks can be affixed to the ceiling
using properly sized lag bolts. The C-channel will span the corrugated steel
and provide multiple anchor points.
For drywall or plasterboard ceilings, special considerations are required:
• If the drywall is on steel or wooden roof joists, locate and tap into the roof joist
with lag bolts.
• C-channel mounting can be used.
• An alternative to C-channel mounting is using large toggle or molly wings with
hex head tap bolts.
NOTE: Make certain joists are properly located before drilling into drywall.
3.3.1.7 Seismic Anchoring
Seismic anchors are designed, tested, and specified for seismic zones 3 and 4.
Seismic anchors enhance the stability of equipment due to the special
characteristics specifically suited to the dynamic and cyclic
loading effects
experienced during earthquake events. As such, anchors shall be used that are
manufactured to particular specifications that make them the most resistant to
the effects of dynamic and cyclic loading effects.
