Abstract:
1. A pneumatic plate element comprising: at least one hollow body made from a flexible material that is gas-tight and capable of sustaining loads from a pressure media under operating pressure; at least two compression/tension elements surrounding the at least one hollow body, wherein each end of each compression/tension element of the at least two compression/tension elements is directly attached to an end of another compression/tension element of the at least two compression/tension elements; wherein the at least one hollow body is located between the at least two compression/tension elements; wherein at least two of the at least two compression/tension elements are connected to each other via at least one pure tensile element; wherein the at least one pure tensile element is connected to each of the at least two compression/tensions elements at a point not corresponding to respective ends of the at least two compression/tension elements; and wherein, responsive to application of a load to the pneumatic plate element under operating pressure, a first compression/tension element of the at least two compression/tension elements is axially compressed and a second compression/tension element of the at least two compression/tension elements is axially tensioned.
