I'd like to convert the attic to a bedroom at a future date and currently have all the first floor ceilings down to replace them. The attic is the perlin and rafter type, what would become the floor joists are only 75x50. I've sized new ones at 170x50 cs3, the span is 7.1m with a load bearig wall halfway, the plan is to use two joists to span the 7.1m and join them where they meet on the load bearing wall, but which is the best way to join them?
Thanks
Jammy
Does the load bearing wall extend above the level of the new floor or would the joists rest on top of it? Is it a studwall?
The Joists will rest on top of the wall and it's a solid brick wall, one skin thick.
Yep, go right ahead. Good to have a thick skin on USENET.
Typically then the joists are cut a bit overlong, like 7.3 m. Then they are staggered so that they overlap on top of the top plate of the wall, nailed to each other and to the top plate.
