Last year, we noticed the floor of “Mustardseed”, one of the two family yurts in écovallée, pulling apart. It didn’t seem to be going back together on its own, so we waited for a dry spell and decided to have a really good look.
This is what we found:
The two short joists by the door had been pivoting on their screws and lifting the floor, which explains why the door was catching on the boards at that point. It did seem strange.
Several of the screws had sheared off, and parts of the frame had moved several inches. Which explains why the floor was so gappy. I imagine this is because I was using green (freshly cut) wood (douglas fir), which tightened up and snapped the screws. (A carpenter might have a view on this.) This choice of wood was driven by necessity and habit – necessity because we didn’t have much money at the time and the wood was cheap, and habit because this is how I’d done it before. (I won’t be doing it like this again.)
The ground was very cracked – and this may have led to some of the movement and shearing.
Some of the frame wasn’t even attached any more. I used that crowbar to lift the floorboards, which all came up easily. I numbered them and stacked them nearby for re-laying.
Which shows just how portable a yurt camp can be (which could come in useful if we ever decide to relocate).
The weather’s holding, so I’ll be taking the joist frame apart and making a new one. Using shop-bought joists. Based on my 12-foot yurt joist frame. There’ll be a ramp this time and it will be even more beautiful than before. Which is one of the other benefits of doing something more than once – it gets better every time.
