While currently building the Hexayurt with Drywall / Composite Stick Frame & Magnesium Oxide ( Mgo) Board Cladding . Re-used Insulation Infill
I was thinking about variations on joining of the panels.
As I am re-using free bottles etc for the insulation, and given the current hurricane in Florida, I was thinking of a free & plentiful, strong flexible seam that would withstand a high wind.
Old worn tyres came to mind.
Note. if the edge sealant does not waterproof the seam, a covering flashing (perhaps of grp sheet strips may need to be installed) )
After trying another method (see following pics) I think its best to:
1. cut both sides off as per the vid below with a Contour Knife & Trimming Blade .
2. Then cut the tread part of the tire one with a metal bladed jig saw. This leaves a flat strip .
3. Put a bead of silicon sealant along the side of tyre or panel edge
4. screw (tyre wall screws well into metal dryall clad wood etc) or ideally bolt (stronger) each side of the tyre strip to the panel.
5. A grp tape reinforced 70mm diameter plastic bottle tube couble be placed inside the stip to act as an air filled support
Other method I tried, if a wider strip is required ( a notorcycle tyre could also be used )
Note: tyre does not need to be cut in half , just do one cut .
Then side wall is cut on bothe sides to allow tyre to be spalyed out flat
A strip of taped , air filled 70mm dia bottles can be used as a filler
Note 6mm Mgo Board bends quite a lot without breaking, (pic), so I will be making a prototype curved panel, which wll perhaps remove the need to have a wedge shaped tre strip installed.
However a curved frame may be more labour intensive
