Building framework using annular sections - has tangential joint collars allowing differential tangential movement of sections

摘要

The annular elements can be circular, eliptical, or triangular and can be made of metal, bamboo or plastics. The tangential joints can be rigid metal collars or flexible bandages made of cables or cords. The framework can be arranged to have a two dimensional deformed geometric configuration such as a rectangular, hexagonal or a similar network, or it can have a three dimensional geometric configuration such as a polyhedral network.
