Precedents - Digital Fabrication & Integral Mechanical Joints

  • Automated product of

(plywood) parts for full house production

  • No additional components
  • r tools for assembly

j.gattas@uq.edu.au SoCE Know Your Neighbours - Folded Structures 01 September 2016 | 9/50 Joe Gattas

Precedents - Digital Fabrication & Ultra-Modular Construction

  • Three parts only
  • Enables:
  • distributed fabrication,
  • interoperability, and
  • no instructions for

assembly.

  • New technique to computationally-generate parts:
  • 1. Parametrise ‘global’ (3D & 2D) geometry 2. Parametrise connection detail

Geometry

  • 3. 1+2 = Manufacturable parts

Testing

  • Uniaxial compression of:
  • 9mm/17mm plywood
  • UB/SHS
  • Parallel/perpendicular grains
  • Glued, press-fit, tight-fit
  • Range of exhibited failure modes:
  • Material fracture
  • Local buckling
  • Beam/plate buckling,
  • Inter-veneer delamination
  • Joint pop-off (friction-loss)
  • Explosive (barrel)
  • Gradual (zipper)
