Adding storage to garage

[StudWall]

Hi all,

Looking for a bit of advice regarding adding some storage to my garage (separate from the house)

It has a Saltbox style roof which gives a lot of 'wasted' space above the garage door (taller end) which I would like to use for storage of some general tat (camping gear, a few garden tools etc etc)

As it is brick walls both sides my idea was to use some face hangers either side attached to the brickwork with some timber across the span. Width is usual garage size so somewhere around 3m

My questions are:

What size and grade of timber should I be using? I guess treated C16

Can I get away with a span of that length unsupported (guess that depends on the timber used)

Anything else I should be aware of?

Thank you

done a bit of research online and found a nice table which tells me:

dead loading 0.25-0.5kN/m2 (25-50kg/m2) i will need 45x145mm C16 to cover the span of 3m ... seems excessively big but i guess that span is pretty large

Never heard of a salt box roof. Are boxes of salt rectangular?

Anyhow, a traditional semi has 3x2 rafters spanning that distance and people store lots of crap in those lofts.

i've never even seen salt sold in boxes ... must be american?!

like this, only garage sized

fair point noted, im probably only gonna store some old camping gear up there

Span tables are giving 6x2 as the "official" section size. Bizarrely, they say the same for floor and ceiling joists which seems odd given that the loading is different.

I can't see why a 4x2 at 400 centres, and noggins at the ends and centre would not be adequate, but obviously there's no guarantees.

If you are putting hangers into the wall make sure that there is enough wall above them to hold them down.

I think 2x4 should be fine, planning on putting some loft boards over them which should help spread the load.

Was planning on using face hangers and screwing them to the wall with a half dozen screws each, or maybe anchor bolts would be more suitable

Finally finished this off at the weekend...

But will it survive the initial blast?

blast?

Ive loaded it up with garage junk and its holding up ok so far

Have you used hangers for timber and screwed every hole into the wall?

 

[StudWall]

Yes sir ...

Looks good... probably would have been easier, and a little cheaper, to have used a 4x2 each side instead of hangers, with a few concrete bolts!
