Abstract (en)
[origin: WO0173245A1] The invention relates to a pneumatic structural element comprised of an essentially cylindrical air-tight hollow body (1) having a radius rh and length Lh and two caps (5), which is manufactured from a preferably textile material that is flexible but has limited stretchability. The side of the hollow body placed under load is provided with a push rod (2) having a length Lh, which is prevented from laterally buckling on the hollow body (1), and both ends of the hollow body are provided with a knob (3). Inside the knobs (3), at least one pair of traction elements (4) is joined in a non-positive manner to the push rod (2). The traction elements (4) extend in a helicoidal and opposed manner while revolving around the hollow body (1) with a whole number of revolutions, and they intersect one another at points (8), which are located on a surface line (7) of the hollow body (1) opposite the push rod (2). The push rod (2), the surface line (7) and the longitudinal axis <u>A</u> of the hollow body (1) define a plane <u>E</u> in which the exerted loads and forces are located.
