Abstract
The pneumatic structural element according to the invention comprises from one to a number of interconnected elements of the following construction: two hollow bodies () with casings () made of textile material preferably coated in a gas-tight manner and having end caps () are assembled such that they produce a common sectional area (). The edging of this sectional area () is formed by two curved tension/compression elements () into which is clamped a web () made of a flexible material of high tensile strength. By filling the two hollow bodies () with compressed gas, a tensile stress σ is built up in their casings () and is transmitted directly or via the tension/compression elements () to the web () and pretensions said web. This pretensioning greatly increases the bending rigidity of the tension/compression elements (). If a plurality of such elements is combined to form a roof, every two adjacent hollow bodies () thus form a sectional area () with a tension/compression element () and web ().
