摘要： A support structure including a tension-compression element is composed of tension-compression bars that are connected in real joints as well as tension straps that extend from one joint to another. The outermost tension-compression bars are connected in one respective knot. Two pressurized hollow members that are surrounded by a cover are arranged on both sides of a plane that extends through the tension-compression element such that the linear tensions σ generated in the cover preload the tension straps on the plane of the tension-compression element, secure the tension-compression bars against bending, and stabilize the joints. The linear tensioning components that extend perpendicular to said plane of symmetry strut the tension-compression element against lateral bending. Air-tight, optionally elastic pneumatic elements can be inserted into the hollow members.

摘要： A pneumatic support having a body (112) which can be pneumatically pressurised and which, when under operating pressure, operationally holds a compression member (96, 128 to 131′) which extends substantially over the length of the body and a tensile member (98, 138 to 141′) which likewise extends substantially over the length (I) of the body at a distance from each other, wherein the compression member (96, 128 to 131′) and the tensile member (98, 138 to 141′) are connected to each other at the end in connection nodes (91), and wherein the body which can be pneumatically pressurised has pneumatic drop-stitch transverse fibre pressure panels (100, 165, 113 to 116).

摘要： The pneumatic support has a pneumatic body which can be placed pneumatically under pressure and which, under operating pressure, operationally keeps at a distance apart a compression member which extends substantially over its length and a tension member which likewise extends substantially over its length, wherein forces are introduced at force introduction points in end regions of the compression member and the tension member into said members and wherein connecting elements are provided between the compression member and the tension member and introduce forces into the compression member and the tension member likewise at force introduction points, wherein, furthermore, the pneumatic body has formations which extend between adjacent force introduction points and which project outwardly beyond a rectilinear connection between the adjacent force introduction points. As a result, undesired distortion of the support under operating pressure, but without operating load, is avoided.
