new joist floor around chimney

M

Do i attach joist hangers into the chimney stack or do i trim and go around them?

i will be spanning the joists into the party wall and off a spine wall. Span is about 4m's. i have a chimney breast in the way and it is 135cm wide. Can i hang 3 joist hangers off here or do i double up the joists at both sides of the chinmey breast and run joists between these 2 doubled up joists ? if i do this should the joists between the doubled up joists be also douubled up themselves?

Double up the trimming joists and the trimmer then fix the trimmed joists to the trimmer with jiffy hangers.

Clear as mud? :eek: ;)

i think so.

the trimming joists sit either side of the chimney breast and so these are doubled up. the joist spanning between these 2 joists (and sits next to the chinmey breast) is called the trimmer?

how can i draw a diagram for you. what should i use as this would be so much easier. i have tried doing something in word but i cannot upload it,

It is also possible to use build in type hangers, but i would only use these if i were building them in as opposed to retrospectively installing them.
