MEP Support (Mechanical Support)
Pipe Hangers and Mechanical Loads:
Hanger loads of up to 50 lbs. can be supported from the slab
provided that the hangers are at least 2’ apart. Hangers
in the slab shall be placed within a zone 6” to 12”
of the joists.
Hanger loads above 50 lbs. and up to 200 lbs. can be hung
from the slots in the joist top chord at any location provided
that the cumulative mechanical loads do not infringe on the
other design loads. The capacity available to support mechanical
loads will vary depending on joist span and the design loads
specified on the plans.
Hangers can also be supported from the joist bottom chords
using threaded rods or bolts placed between the bottom chord
angles. Hangers from the bottom chords must be placed immediately
adjacent to the panel points (where the web connects to the
chord). Do not weld or drill into the Hambro joists.
We have not addressed the type of hangers or anchors that
will be used. This should be examined by the structural engineer,
architect and mechanical engineer. Please make certain that
a proper hanger design is used to eliminate any impact vibration
in the slab.
