Pneumatic structural element

Abstract

The pneumatic structural component according to the invention comprises an essentially cylindrical airtight hollow body (1) with radius rh and length Lh and two caps (5), which is made from a flexible, but low-stretch, preferably textile material. The hollow body (1) on its side exposed to the loading it carries a pressure rod (2) of length Lh, which is secured against sideways buckling and at both its ends carries a node (3). At least one pair of tension elements (4) is joined to the pressure rod (2) in the nodes (3). The tension elements (4) run screw-shaped and contra-rotating in a whole number of circuits around the hollow body (1) and intersect each other at positions (8), which lie on a surface line (7) opposite to the pressure rod (2). The pressure rod (2), the surface line (7) and the longitudinal axis of the hollow body, referenced A define a plane E in which the engaging loads and forces lie.
