I'm currently planning out a loft conversion, and I'm after some advice on how best to support the joists. My structural engineer has spec'd 152 x 152 x 30 UC beams for the floor, one of which runs through the middle of the room, these support 47 x 147 (regularised 50 x 150) joists, my problem is how ensure the joists will be proud of the steels so that it does not contact the flooring. I can think of 3 options:
- Fit larger 47 x 170 joists into the web of the beams (would require some notching and maybe structural calcs)
- Bolt timber into the web of the beam, use face fix hangers to support the joists, might require larger 47 x 170 joists to ensure the hangers can be fully nailed while still leaving the joists proud of the beams
- Bolt timber into the web of the beam, shot fire timber to the top of the beam, use jiffy hangers and 47 x 147 joists
Any advice on what's best? As always, I'd like to minimise cost and floor height. Thanks for any help
