Notes (for all brick-to-grade cantilever details):
1. Details applicable to residential applications only.
2. I-Joists and LVL shall be properly designed to
carry the cantilever loads.
• Reinforcement may be required.
• Maximum uplift at backspan shall be limited to 200 lbs.
unfactored reaction (or 350 lbs. factored reaction).
• I-Joist girder shall be properly designed to carry
the I-Joists and LVL. Double I-joist and filler
blocking may be required.
3. Indicated nails are box nails or equivalent:
• 8d, minimum 0.113” diameter x 2½” long
• 10d, minimum 0.128” diameter x 3” long
4. Full-depth blocking panels may be installed directly
over the wall instead of the flat 2 x 8 blocking
shown.
5. Details shown are adequate for end stability of the
I-Joist itself.
• Additional lateral resistance may be required in
high wind and/or seismic load areas. Consult
with the project design professional of record.
