Support system for spreading out membrane - has rope or chain pressing together pearl-type pieces into force-absorbing curves

摘要

A tension device (3) presses together the pearl-type pieces to form a force-absorbing curve (4) with bearer, support and tension functions, whereby the alignment of the curves and the fixation of their position are defined by the membrane (5) itself. Several curves can be formed by only one draw component and one or more tension devices (3), and tunnels on the membrane are used to align and fix the curves. The pearl-type pieces are formed with their ends positively or negatively conical. With straight pearl-type pieces, obviously angled such pieces are used for effecting abrupt direction alterations of the force-absorbing curves (4). USE - To erect tents, stadium covers, and shrouds for boats on land.
