CONSTRUCTION
Our construction starting point was that we wanted to make
our truss joints completely out of wood if possible. Necessary
for this was a construction based on compression. Therefore
we used one tension wire to achieve compression in all three
important joints. This also insured we could work with a
relatively ‘light’ construction in wood.
The angles of our construction are based on research we did
for optimal stargazing and lying down. Furthermore the height,
width and length of our constructions followed from these
angles. For the main trusses we use pine beams, 90x90 for
the column and compression beam, and 180x90 for the main
diagonal beam. The steel tension rod is 12 mm.
