Rim Board may be used in lieu of I-Joists.
Backer is not required when Rim Board is used.
For single I-Joist, see detail 1A
for capacities. For double I-Joist,
the table capacity may be doubled.
Filler block is not required
for this detail.
1A
All nails shown in the details below are assumed to be common nails unless otherwise noted. 10d box nails may be substituted for 8d common shown
in details. Individual components not shown to scale for clarity.
Attach I-Joist to

8d nails @ 6" o.c.
(when used for lateral
shear transfer, nail to

toe nails @ 6" o.c.
One 8d face

To avoid splitting flange, start nails at least 1½"from end of I-Joist.
Nails may be driven at an angle to avoid splitting of bearing plate

I-Joist blocking at mid-span (or at other locations between supports)
may be used to reduce vibration. Two recommended methods
of attachment are shown. Other fastening methods are possible.
Method 2:
Minimum two 10d nails face nailed
thru OSB web of I-Joist blocking
into 2 x 6 vertical block and clinched
(preferred) or nailed thru 2 x 6 and
clinched on back face of OSB web
of I-Joist
blocking. In
addition, nail
thru OSB web
of full-length
joist into 2 x 6
with minimum
two 10d nails.
Repeat at opposite
end of I-Joist
blocking.
Method 1:
One 8d nail toe nailed at each
side of top and bottom flange
at each end of I-Joist blocking.
Caution: Effective toe nailing
may be difficult to achieve due to limited access of pneumatic nailers.
The builder shall evaluate installation for potential of nail squeak.
Notes:
1- I-Joists do not always need blocking (bridging) between supports. I-Joist blocking must be installed
only where specified by the building designer.
2- Use of construction adhesive is recommended at wood-to-wood contact areas.
3- It shall be permitted to offset (stagger) I-Joist blocking up to the flange width. Nailing
thru the joist flange into the ends of the I-Joist blocking is not permitted.
1G
Blocking panel
see details 1A and 1B
for vertical load capacities.
Blocking required over all interior supports
under load-bearing walls or when floor
joists are not continuous over support.
In high seismic areas blocking
is required at all intermediate
supports.
8d nails
at 6" o.c.
to top plate
Load bearing wall above shall align vertically
with the wall below. Other conditions such as
offset walls are not covered by this detail.
