Hi there.


What methods are there to have a ceiling a foot lower than the roof
rafters it ties together? Like this:

The question arises because the roof rafters must be tied to stop them
doing the splits.


Thanks, NT

Not the latest hi tech solution but a U shaped wrought iron bar was
used to do just that in my house 400 years ago and it is still holding
strong. Bet it doesn't meet building regs tho

IANASE.

You can put a beam or wires to tie them together at eaves (or higher) level.
You could tie the eaves to the low down joists using modified/specially
designed "gallows" brackets, assuming they run the same way as the rafters.

Why do you want a lowered ceiling ?
But if so, you could have a look at commercial false ceilings which include
insulation.

I have all ceilings like his: Upper storey floor is a meter below eaves.
Ceilings a are a meter above it.

Structural engineers suggested all ceiling joists bolted to rafters, and
all floor joists bolted to stud uprights. (its a timber frame).

so floor and ceiling joists all in considerable tension.

Oher methods suggested were fabricating U shaped steel sections to be
buried in walls to take tensiles sttresses and connect the two walls.

I was wondering about that, but I see one possible issue. As the joist
bends it causes the top point of the steel triangle to move in and
out. I dont know if the amount of movement involved would be an issue,
but I wouldnt be surprised.

Lets say for example the joist is 10' long, and the steel triangle 1'
long each way. For a max 10mm of joist bend, there would be a max 1mm
movement at the roof rafters. I dont know if thats an issue or not.

Presumably where the triangle is tied to the brick wall at the bottom
there would need to be a spacer between wall and triangle, so that the
brickwork is not moved by normal joist bending.

Anna's U shaped ironwork sounds like a very good solution, and I cant
think of any reason for it not meeting BRs, but it also sounds like a
relatively pricey option. In fact thinking more about it, it would
have exactly the same issue, though the iron might be much more rigid
than wood joists. You say its doing fine Anna: is it a brick wall, or
timber frame?

than wood joists. You say its doing fine Anna: is it a brick wall, or

Timber frame. Extremely over engineered

that means it wont mind moving about a little: brickwork might object.

Thats a vain attempt to be anonymous :-)

It comes out well on my computer (of course) but I use fixed width
fonts. Its not a foolproof design and it doesn't work with some fonts

Maybe you are using a font it doesn't like? Or do other people have
the same problem?

It works fine for me, but of course I use a fixed width font (Courier)
with a newsreader in a terminal emulator. Even smileys get broken otherwise.
