Has anyone any experience of installing a suspended timber floor into
a new building / extension ? I understand that according to UK
building regulations, new joists have to be tied into the new wall
using galvanised restraining straps at max 2000 centres and these have
to be taken over at least 3 joists with tight packing between. I also
understand that this is normally achieved using what is in effect an
'L' shaped strap with the short edged pulled up tightly behind and
built into the block wall and the longer end secured on the top of
All well and good, but what can you do if the top of the joist doesn't
align with the horizontal mortar beds in the block wall ? Can they
be installed on the bottom of the joist ?
What if it still doesn't align, is there some other method to achieve
the same thing ? I have been wondering about the possibilty of
obtaining a strap which can be intalled in a vertical mortar gap with
a bend to pull it up against the back of the block and then a twist at
the front of the block so it still sits on top of the joist.
Does any of this make any sense to anybody?
