Guide rail for scaffolding - ideas?

[gregog]

Morning All,

Looking for a bit of help and advice - the more comments and ideas the better!

 

Essentially, I am hoping to make a guide to be able to run a 48mm Aluminium scaffolding tube through. (at this time, its use is irrelevant, I need to know if I can do it first!)

 

I was hoping to get a piece of unistrut approx 50mm wide and simply slide the ally tube through this, creating a guide to ensure if runs straight. However, unistrut only do up to 41mm wide. An alternative coiuld be using a cable tray, which I am looking into - but unitstrut being solid, is IMHO going to be better and more suited for the job. I am going to use universal clamps at the top where a guide rail is not appropriate; but can anyone suggest anything that I can use to sit the scaff tube into to act as a guide rail?

 

Many thanks in advance,

Gregog

We made a theatre set with flats that pivoted by having a base piece of 38mm tubing (Ali tube inner dimension) that the tube sat on top of and spun round - I can't quite figure what you're trying to do but that would give a fixing that it could pivot around and slide off/on?

Not sure and would suggest a trained scaffolder be consulted but we used to remove the centre metal disc from sleeve couplers, if my thinking is on the same lines as yours. Adding an extra nut inside the coupler kept them at the required spacing and secured things.

I think we need a lot more information is we are to be able to help.

How about C section steel (sometimes called channel)

Like this: My linhttp://www.parkersteel.co.uk/Matrix/5/Channels+-+Tapered%20Flangek

You'd have to call them and find out the internal dimension.

The C section steal is a good idea.

you could modify a external conector, and posibly atatch the universal clamp to the exsisting threaded holes. thou it wont be able to take much of a load.

wouldnt a key clamp be perfect for (what I think) your trying to do? will definately be sturdy and you just remove the tigtening, which is a grub screw, and would then also give you the option to be able to lock it off if needed...

 

you can see them here: http://www.key-clamps.com/Catalogue.htm

 

A2/3/4 would be suitable, as would some of the others but these will definately allow the tube to pass through completely whereas a lot of them have an end stopping you!

 

but as said before it would be useful to know what you are trying to achieve to give more helpful answers, and im quite intrigued now!

Thank you all for your responses and help.

 

After looking into C Section Steel, that top hat is my best option.

Essentially I am using a garage door opener to drive an attached scaffolding tube. I intend to use the C Section Steel as a guide rail to ensure that the scaffolding tube runs straight and true :)

 

Thanks again,
