Scaffolding tube – How strong with a straight coupling?
Another from the ministry of silly questions…
I’d like to support a lightweight tarpaulin over my back yard. Single slope, high side attached to the house and low side attached to a scaffolding pole, running horizontally between two walls.
Fair weather, no high winds or pooling. The run of pole would be 8 meters.
The longest poles seem to be 6m, so I need to use a coupling. Will this be strong enough – ish?
I imagine the most stressed point would be just around the edges of the coupling, so If I used two joints in the bar, wouldn’t I half the strain on a single one?
Also if I made the joints at 1m and 7m would that be better than to have a joint in the middle where the most flexing will be?
Also bit more expensive, but with Aluminium the bar will be 20kg lighter – buy will it be as strong joint wise?
Will a tubular coupling be as good as a external one?
If anyone knows.. Thanks!
I think I'd rather use a sliding tube system. One to fit into the other with enough lap to properly stabilize the load. No coupling required. Just a couple of bolts through drilled holes.
