OMO: Stop me falling on my rump!

[Brettus]

Another weird and wonderful one for the weird and even more wonderful people of the org!

I've got a hammock that I'd like to be able to hang indoors (because I'd like to use it for more than a fortnight a year) it has carabiners on each end (and straps to adjust to length) and I'd like to hang it end to end in our conservatory with brick walls either end. I've eyed up something like this:
http://www.diy.com/nav/fix/hardware/nuts-bolts/eye_bolts/B-and-Q-Eye-Bolt-M8-x-60mm-9372122
but wondered with it being a pulling force if that would be sufficient or if I shouldn't have a second set of bolts like that a few courses of bricks higher which I thread through so the pulling away from the wall is lessened a little?

Anyway, I've clearly run out of brain cells for this one and I'd like to learn the easy way rather than the bruised and painful hard way :)

Thanks in advance

wind em tight and they'll hold you.

of course whether the wall will or not is a different matter.

If it's not a supporting wall it might not.

Damn, that was my other worry that I forgot to mention.

They aren't supporting walls, I'm gonna pull my building in on myself aren't I? (wonder if there is a market for that, "controlled" demolition in comfort)
hmm... There are big wooden beams in the bedroom, I'd wondered about putting similar bolts in those but wasn't sure if I'd weaken the beam then with even more disastrous consequences

[Spank86]

Those eyebolts are heavier duty versions of the ones we use to string up overhead cables.

They take a fair bit of weight if placed in the centre of a brick but you'd need to go quite a way down from the top layer even on a supporting wall.

I can't remember our regs off the top of my head but I think it's 4 full bricks down for hanging a dropwire off which is a fair bit of weight (and I could hang off if I was bored/stupid) but on a single skin wall, I doubt it would fall down but I'd want to know the quality of the mortar in case you pull a brick out and how sturdy the wall si because you don't want it bowing in. Any orgers in your area builders?

The wooden beams might be a possibility if they are big enough, what dimensions we talking?

[Spank86]

You could of course always try simply believing it wont fall down but I wouldn't recommend it.

[Brettus]

Hah, yeah I'm more nervous of it the more I've thought about it now. I think that is what makes people do many stupid things, an incomplete idea of the consequences!

Thanks for the advice, I'll check on the beams later, I'd say they are 20cm by 8-10cm off the top of my head. they run through both cottages

[Teejayexc]

Why not buy or make a frame/stand for it?

Google it, there are hundreds out there.

[Brettus]

I don't like the idea of the frames as I'd like to use this in more places, I'd struggle to get a frame into the conservatory etc. But that might be my only option, or perhaps a bigger bracket spreading over a larger area on the wall perhaps?

[Teejayexc]

Do you have access to the other side of the wall? Maybe a plate would spread the load?

[Bluepete]

Can you hang it from the ceiling beams with a long pole between the ends to keep it spread apart?

Pete ;)

[Brettus]

are you thinking more like this Pete?

I can stretch it over the width of the room from beam to beam, just want to check I'm not gonna bring the roof in if I drill a big bolt into it ;)

[Bluepete]

I have one of those, but was thinking of a normal hammock suspended from the beams with a long pole between the ropes to keep them apart and stop the hammock sagging in the middle.
We take a string hammock on holiday and hang it froma tree with a pole spreader. Works a treat!

Pete ;)

[Littlepeahead]

I have a better idea. Can I come round and set up a video camera. Then you connect the hammock to the paper thin walls and when the whole room collapses in around you I will sell the footage to You've Been Framed and buy myself something nice with the money.

those are quite hefty beams, I would say you'd be okay as long as you aren't planning on boring a massive hole in them.

a screw in eyebolt might be better for that, can wind it in nice and tight without taking a massive chunk of wood out, especially if it goes in at an angle to the pull of the hammock.

Screw in eyebolts in the beams will do the job with no worries.

[Specialone]

Bolts (m8, m10) even in a single skin wall will take massive pull out loads, providing they aren't in thermal blocks like thermalite type ones, don't even bother if you have these.

Cross bolt loads are more likely to break the bolt rather than pull out.

Take some pics of the location and measure the rough height of where you were thinking of putting the bolts.

Btw, go to screwfix or toolstation, there will be a better range and they will be cheaper.

I was more concerned as to how close to the top of the wall it was than the loading of the actual bolt.

I have no doubt the bolt would hold in the brick it's if the brick would hold in the wall.

Dredging this one up, might be heading to screwfix at lunch and I'm still wanting to hang the hammock up somewhere and the beams are seeming the best bet, what am I best getting, anything from this lot? http://www.screwfix.com/search.do?fh_search=eye+hook&fh_view_size=20

Thanks for all the help and replies so far, might've saved me a costly mistake :)

[Spank86]

they look a bit insubstantial. I'd be looking for a 3inch screw thread on a hook.
