  • 1. A platform that can be raised
  • 2. A platform that can be raised
    • We are going to make a bridge with a platform that can be raised. The structure will be made with triangles of paper only
  • 3.
    • Before we start with the bridge we are going to do a resistance test on the traingulated structures
    Triangles resistance test
  • 4.
    • In order to do this project we need these materials:
    • Paper
    • Thermofuse glue
    • Cord
    • Plywood
    Triangle resistance test
  • 5.
    • First of all we will make the paper tubes. You roll the paper around a wood bar.
    Triangles resistance test
  • 6.
    • Then glue the edge with a little glue. Take care because if you use too much, it will get stuck to the
    Triangles resistance test
  • 7.
    • Since our tower is 30cm high we have to make:
      • 4 tubes 30cm long
      • 16 tubes 10 cm long
      • 16 tubes de 13 cm long
    Triangles resistance test 4x 30cm 16x13cm 16x10cm
  • 8.
    • With the tubes you will form two sides of the tower
    Triangles resistance test Make two of these 30cm 10cm 13cm
  • 9.
    • In order to connect the bars properly try to make a gap at the end of the shortest bars
    Triangles resistance test
  • 10.
    • Once you have two sides you can start joining them together like in the picture
    Triangles resistance test 2X
  • 11.
    • Remember that the more triangles the stronger the structures will be
    Triangles resistance test
  • 12. Triangles resistance test
    • Finally we will put all the towers together to make them more resistant.
    • The board has to be 30x40cm in order to cover 6 towers
  • 13. Triangles resistance test
    • We will check the resistance of our triangles¡¡
  • 14. Triangles resistance test
    • You have only six days to finish it, so
    • Let’s work
  • 15. A platform that can be raised
    • Now that we know how to make triangulated structures we are able to build a platform that can be raised
  • 16.
    • As you did before, o nce you have two sides you can start joining them together like in the picture
    Triangles resistance test 2X
  • 17. A platform that can be raised
    • Attention¡¡¡¡¡
    • This time we have to leave a gap where the platform will be placed
  • 18. A platform that can be raised
    • This is the handle that will move our platform
    20cm 3cm 8cm 5cm
  • 19. A platform that can be raised
    • The platform has to be 20x10cm and you have to make it as you did before
    Cover it with a piece of paper 10cm 13cm 20cm
  • 20. A platform that can be raised
    • The platform form will be made with tubes and has to be movable, so make sure that one tube can be placed inside the other
    5cm
  • 21. A platform that can be raised
    • Then you need to insert the crank inside the tower, using two tubes of 3cm diameter
    Cranck
  • 22. A platform that can be raised
    • Finally you only need to connect the platform to the tower with a cord, making a knot at both ends
