Bamboo Structures

From DT Online

What to Make:

Build a structure as wide as your classroom, or as high, or both!

Bamboo Scaffolding used in Hong Kong



What to Use:
  • Use only Pea Sticks or Split Bamboo garden canes each approximately 1 metre long (i.e. between 600mm and 1200mm)
  • Use only elastic bands to make joints.
  • Any filled in panels may be made by adding coloured tissue paper fixed in place using P.V.A. glue.


Things to find out and think about:
  • Look at large framework structures (e.g. truss bridges, scaffolding, garage forecourt canopies, electricity pylons) either by visiting them or searching for photos using the internet.
  • Note the shapes made by the framework - how often do you see squares or triangles? Why do you think triangles are so common?


Some ideas:

Ways of Making:
  • Lash together lengths of cane to make triangles using elastic bands - simply hook the elastic band round one end of a cane then keep it stretched tight as it is wrapped around the canes forming the joint.
  • Link the triangles together to form pyramid like structures (e.g. either square or triangular).
  • Join several pyramids together to create a large structure (e.g. a tower, a bridge across a classroom or a pyramid to walk inside).

Safety Point! Cane structures are very light in weight so a safe way to build a tall structure is to lift and add extra pyramids from underneath rather than trying to stand on desks and chairs etc.



Testing:
  • Does it reach the classroom ceiling or allow you to walk under it or inside it?
  • Which shapes worked best - triangles or squares?


Further Work:
  • Think of making structures involving or including other shapes or polygons (e.g. look at how footballs are made)
  • Find out about Geodesic Domes by searching on the internet.
  • Even larger models can be built similarly by binding together long lengths of card tube, plastics pipe or lengths of timber using cable ties, gaffer tape, duct tape or similar.
