roof joists...can i nail stuff to them?

[jeed]

Right, im getting sick of paying a fortune for visiting the climbing wall, so was planning on building a bit of a home training thing in the loft. I've seen examples where people have bolted ply sheets wiht bolt-on holds to the joists in their roof, but I haven't seen how these hold up in the long-run.

Just wondering on what people think of the long-term risks of bolting on big sheets of ply, plus climbing holds, and then swinging on them.

Cheers

that'd be roof beams, obviously, not joists. Brain fart.

The roof was designed for a 'load', if you are going to be putting sheets of ply & swinging (Mmmmmm) then you need professional advice.

 

[nstreet]

You must have a very high pitched roof, just about standing room only in ours.

 

[jeed]

nah, tis not hugely high, enough for a bit of a swing

Its a victorian terrace, and have been advised that there's probably enough meat in the beams to take it as long as we screw the boards in about 12" apart. Probably going to be one 6x4 16mm board screwed directly to the beams, probably covering 7-8 beams, (40deg overhang) with a vertical bit underneath, screwed to the cross-beam and the loft floor joists.

Professional advice is what im after!

 

[Diyisfun]

Opps sorry, You were asking for views. I gave one.
If you are after professional advice, you will need an inspection.

 

[jeed]

apologies...didn't mean that to sound snarky. Meant to say that I was after some information, instead of someone telling me i needed information, which i know.

Sorry for any misunderstanding

Any photo?

 

[jeed]

i'm afraid not, might be able to get one up at the weekend. Beams are spaced every 18", and are about 4"by7". We've had a wood inspection before we moved in and apparently they're sound, no woodworm or damp.

Thanks

Can't you fix the holds directly to the roof beams, why do you need the plywood?

 

[jeed]

possibly, though someone i was speaking to recommended using ply to spread the load of grabbing a hold across a number of beams...

hi , the rafters , if 7 inches by 4 inches , will support your weight and the ply wall your are looking at building , due to the fact that roofs are over engineered , especially a victorian terrace , to allow for snow loads etc , and a traditional pitched roof works off triangulation, making it very strong ..

They be Rafters Monkey boy

4 x 7 (100mm x 175mm) rafters do sound massive but it all depends on the span and pitch

Also are you 8 stone dripping wet or 18 stone on a good day?

You may have to check the weather forecast on the days you want to spend 'hanging out' in the roof to ensure winds or snow arent forecast.

Depending on your ceiling insulation it can get damn hot in lofts so you may need to be prepared to sweat alot.

How about puting them on your outside wall (gable wall?) Obviously away from windows or its just an invite for thieves. If you have a wall without windows then your uncles robert. just a vertical climb but better than nowt and there should be no structural worries
