Abstract
The pneumatic support according to the invention has pneumatic bodies 61 to 63 which can be placed under pressure and which operationally keep a compression member 51 and a tension member 52 at a distance apart, resulting in a pneumatic support with high loadability but also, disadvantageously, with high operating deformation. The connection elements 57, 58 extending in a zigzag shape between the compression member 51 and the tension member 52 over the length of the support 50 are preferably diagonal struts formed as flexible tension members and reinforce the support 50 with respect to the pneumatic supports of the prior art in such a way that the deformation of said support in the case of an asymmetrical load, as is the case with a bridge over which vehicles travel, is for example still 10%.
Claims16
A pneumatic support comprising:
- a body (23, 61, 62, 63) which can be placed under pressure pneumatically, which at operating pressure keeps a compression member (24, 51, 120), which extends substantially over the length thereof, and a tension member (25, 52, 121), which likewise extends substantially over the length thereof, at a distance from one another in an operative manner;
- connection points being provided on the compression member and on the tension member for at least one tensile connection element, which extends between the compression member and the tension member
- wherein the connection element extends between the compression member and the tension member in a zigzag-shaped manner over a plurality of connection points in each case both in the region of the compression member and in the region of the tension member.
