Attaching timber to scaffolding shed frame ?

[CompoSimmonite]

Last year I cut a load of new scaffolding poles into the lengths required to build a basic 10' x 8' frame for a new shed / workshop with pent roof. The proposed site slopes so it'll be on "legs" concreted into the ground meaning no need for a slabs or concrete pad base . I've got loads of KeeKlamps so all the joints are sorted.
Plan is to clad both inside and outside of the frame with insulation in between. That means timber bearers need attaching to the scaffolding poles. When I built my carport I used tight fitting saddle clamps and whilst these will work again the number required means it'd be a very expensive method so have been trying to think, without success, about alternative methods of attaching timber to scaffolding poles.
Best I can come up with is drilling 50mm holes in 4" x 2" timber lengths so they will slip over the 48mm dia poles. Hopefully the couple of mm different will help with any inaccuracies . Another thought, probably better, is similar - clamping two lengths of 2" x 2" timber together before drilling holes so they can be fitted either side of the poles and then screwed together.

I have brain fog (unfortunately becoming more common / normal for me) today and can't think clearly so wonder if anyone has other suggestions for attaching the timber to the poles ?

Cheers.

I've had to do a few polytunnel type things and really the proper clamps are the business. Job goes so easy with them. That being said, I also know how pricey they can be so I'm not surprised it's prohibitive.

You could do a simple jig and use flat bar, say 40 x 4, to fashion your own. It only needs to be the top arc of the tube with two flattened tangs, like an omega sign. The tangs get a hole in each and then coach bolts to hold the wood on.

Not a magic bullet answer sorry!

It's a bit of a bodge, but cheap.... you could bend universal threaded studding into homemade u-bolts - or, as you suggest, clamp 2x2 either side of the poles - again using studding or bolts.

Hi, either the 4x2 or the 2x2 will work. As 4x2 is the cheaper standard cut of timber, what about drilling your 50mm holes at the right spacings, then rip the 4x2 down the middle, then screw them together either side of the pole. The material 'lost' from the cut will provide the clamping force on the pole, the only cost then would be the screws.

Any way you could use exhaust clamps?

Tek screws through your cladding into the scaffold poles. You'll have to pre-drill carefully but otherwise quite straight forwards. If you are using horizontal planking then alignment is easy as you can see the pole above the bit that you are fitting. If sheeting then very careful marking out.

If you're cladding inside & out could you just use wooden blocks (or lengths of timber) slightly thinner than the diameter of the poles and screw the cladding into these so the cladding itself grips the poles.

'tight fitting saddle clamps' and just fit 3 rails top middle and bottom just like a fence then fix everything to the rails

id just pre drill the poles and bolt it on using coach bolts

All the pros use perforated strap. It's quick, easy and secure.
