Looking up at the joists and floorboards of the rooms above:
The joist lowest in the picture is 170mm by 47mm
The old timber in the middle (supported by prop) is the bottom of a wood frame with cob and lime infill wall between 2 upstairs bedrooms
The joist highest in the picture will be replaced by another 170mm by 47mm joist, closer to the middle timber.
I'm going to end up with:
new joist - 100mm gap - old timber - 40mm gap - new joist
I'd like to support the old timber frame wall between those two new joists, and am thinking of using wooden block between the joists and old timbers, then bolts all the way through, so that it will look like this (literally) back of an envelope sketch:
Is this a sensible way to do this, or are there better ways?
I'm assuming timber connectors would be a good idea between the timbers and blocks?
Is it possible to recommend a bolt diameter without lots of calculations?
Worth mentioning that this timber frame wall has been apparently unsupported from beneath for decades without any apparent movement. It's not possible to get a clear sense of how it might be supported from either end further up the wall.
Thank you for any thoughts, cheers, Stephen
