So I figured I’d post this here. It is a tree bar component which I made in SketchUp last night. It would be used to build half-circular platform bases which could act as mounts to build elevated walkways through trees.The idea is, with enough of these platforms you could start building an actual tree city.
The design uses a mounting bracket (pink) to hold a triangular beam (red) which has a stability extender at the end (orange). Most of the downward force will be applied to the extender rather than the beam. To prevent the three bolts from shearing, there is a tension relieving rod (blue) which is pre-fabricated inside the triangular beam. When the extender is pulled out of place, it takes the rod with it, sending all the tension forces backward into the lower part of the triangular beam.
That’s the theory, anyway. For the record, I am NOT a civil engineer. That said, if a civil engineer wants to test this, I’d love to be a part of something like that!
