If you wanted to add another floor to a room (dont ask) can you use joist hangers or are they more designed for flat roofs??

How much weight will they take? (enough or not enough is the correct answer) or is it time to get a hammer and chisel and a pack of slates?

Fasteners? Window fixers / rawl bolts?

Cheapest place for 6x2's or similar.. (to add an upper area to a workshop)

joist hangers are fine for floors, roughly £1.50 each
6x2 needs to be stress graded and costs, roughly £1.60 per metre

hangers should bear directly onto supporting wall and joists should be
cut in tight
hope this helps

Nice :)

Saves time...

Laser level would make this easer though!

David,
So long as you use the chunky ones with an angle on the top and put a groove into the wall for it they'll be fine!! unless you're gonna put the car up there!!

No, no car.. but maybe some furniture if you catch my drift.. (not my workshop.. A mates.. would like somewhere clean to eat and rest whilst he's at work.. IE work all day, then sit upstairs and have some lunch.. somewhere away from it all but clean..)

thought they would be fine, but theres no harm in checking!

dont think you will get away with 6x2's for joists as nearly everwhere now is 9x2 but they have joist hangers in all the new houses and they cover over 5 m stretches with the new plywood joists :)

I will get away when it aint a house and no building regs.. if you get my drift.. just an out building 'workshop'

will go with whatever is about :D

Also depends on condition of wall with which you are joist hanging onto, how the wall is restrained at ends, and how high up the wall they are. If single blockwork construction then joists hangers not advisable.

200mm x 100mm C16 timbers at 0.450m ctrs spanning 4m max will kill it.

Roger.. Ill have a look.. I seriously doubt its single block work due to the age and size :)

David, I guess your mate won't care, but a mutual friend (Max) wanted to split his unit into two levels, but the health and safety guys wanted all sorts of ****e - and without that ****e being done, he couldn't get insurance for the place.

So he ended up not doing it :(

Nick, will tell you when I see you.

Needless to say it will not be an issue :)
