There may be an easier way (easier than internal cabling) to make a hurricane hexayurt using only steel angle corners bolted to the boards:
Referencing: http://www.appropedia.org/Hexayurt_schematics - the angle between vertical boards and other vertical boards at the corners is 60° - the angle between the vertical boards and the roof is also 60° - the angle between the boards on the roof cone is 29.5° Adding it up: - 12 pieces of 60° angle to connect 6 wall panels to each other, and to 6 roof panels - 6 pieces of 29.5° angle to connect 6 roof panels - 6 pieces of flat plate to connect 12 boards to make 6 wall panels - Bolts: 24 angle pieces with 12 bolts each (as a guess) = 288 bolts (and nuts, and lock washers maybe, whatever it takes to do it right) - 1 custom vertex cover to allow a stove pipe? Total: 24 pieces of angle steel, each 8 feet long (or a bit less than 8 feet to allow them all to fit flush without overlap): 24 x 8 = 192 feet of angle. Notes: - angle doesn't have to be thick steel, it could be as thin as will work (needs testing) - angle could be made from aluminum, but the point of failure will likely be where the bolt fastens to the angle, and steel is stronger and (probably) cheaper than aluminum - angle does cover the gaps between the boards, thus (mostly) sealing the yurt = two solutions in one. - angles should be pre-drilled, done at time of manufacture. Sourcing in the US via Thomas Catalog: http://www.thomasnet.com/nsearch.html?cov=NA&what=Steel+Angles&heading=79820601 The hurricane hexayurt does have to be anchored to the ground somehow. Tiedown or directly anchored to the ground? Maybe something attached to the bottom of each vertical wall angle, and anchored with rebar?
