Following from my previous post about moving a non-load bearing wall and building another, I’ve come to the conclusion life would be easier if I replaced it with a stud wall.
Project is for a 3600x2520(L,H) stud wall constructed with 47x100 timber, soundproofed with soundKnauff Earthwool Acoustic Roll, and with 15mm GYPROC SoundBloc.
Although the new stud wall is a lot lighter that the current solid wall, it’s not going to be as close to the sleeper wall. The diagram above shows the new position of the stud wall in relation to the to sleeper walls, which are 23inches left and 18 inches right.
Being as I’m going to submit a Building Notice rather than full plans, I’ll probably start construction before the first inspection (due to my irregular work hours). Now my research shows I’m likely to be asked to strengthen the floor joists, which are 54x100 with a 400mm distance between them.
The questions I have in my head are:
1/ How is this reinforcing done ?
2/ Is it a matter of buying similar graded 54x100 timber and attaching it to the side of the current joists (see diagram below)?
3/ How far should the reinforced part of the joist overlay the sleeper walls?
4/ Should I reinforce every other joist which is under the new stud wall?
5/ How would I join the old joist and new timber, screws or are there special bolts?
If someone could answer those questions I’d be very happy
Thanks for reading,
Robert
