spurs/pickups: tension & compression

[paulscaff1]

I've posted this in the study group but it seems a bit quiet.

When using spurs to pick up a cantilever from above,

Am I right in saying that the spurs should be laced in compression ( doubles outside\inside)

And from below, laced in tension (doubles outside/outside)

Its just that it seems some scaffs seem put them on wherever is easiest, unless I'm wrong?

draw a picture.. im confused...

Surely, Rakers/spurs from above the supported lift would be under tension and picking up from below under compression? The Tubes & fittings. As for fittings outside or inside of the Aberdeen or bridal transom which ever is easiest/practicable given the constrainst of the job or habbits. Think a designer would say it makes no difference. Just put your checks on the right side! Think weve all seen a few jobs with checks doing bugger all

Dont u mean supplementry couplers lol

Yea the spurs from above would be in tension, there for they would be laced in compression so that its pulling back

Probably doesn't matter either way, if it fits in the textbook way then I'll do it that way.

Often get questioned why I'm lacing it the way I do lol.[COLOR="Silver"]

Thats wot i ment lol

Kind of the same thing when talking about plan bracing beams. Always inside to outside for compression I was taught.

Can alan reade confirm if it matters which way?

Complected malarky this old scaffolding game , now i have to worry about compression and tension and supplementary fittings

Rather than in side out on spurs isn't it on top under Neath ??
