Roof Inversion! Eeeekk!

[TalkingTrees]

Evening,

Just a wee bit gusty over here. I had noticed a slight twist happening with my crown wheel and poles from previous winds, and realise now that this must have weakened the structure... After the 120km winds on the weekend, I came home to find the roof inverted and a nice funnel of water pouring through the middle. Luckily, it's pretty minimal damage (books, bed and clothes all dry!! yay!), no rips to damage to canvas or walls OR crown... but the galvanised nail that holds the 'nodes' (at the end of the poles that fit into the crown) have all been twisted either off or at a 60/90' degree angle..

I'm looking for ways to prevent this ever happening again? One pole came down and snapped over the bed - a nice lil dagger into the centre of a pillow - and although I love my yurt life and home beyond words, I do want to be able to live a long and happy life in there!

I am thinking of using stainless steel rods to connect the poles & nodes.. and extending the rod a lil extra further past the crown wheel so I can thread on an extra nut so it can't come out?

The walls are currently tied together with a strap - would wire hold more integrity/strength?

How do I fix a twisting roof/crown wheel if I notice this? Is that a normal 'settling in' of the poles?

Is it stronger with having the 2 support poles holding up the crown, or is it better to have the weight sitting on the walls?

Thank you! Xx
