Abstract

A flange plate for a manifold of an exhaust-gas system for internal combustion engines, which flange plate can be fixed via at least one holding device to an exhaust-gas outlet connecting piece of the internal combustion engine by a first outer layer, formed as a mounting layer, which can be placed at least partially directly or indirectly against the exhaust-gas outlet connecting piece via a seal, and the flange plate can be applied to the holding device by a second outer layer, formed as a holding layer, in order to generate a holding force F, acting at a right angle to the mounting layer, for sealingly placing the mounting layer against the exhaust-gas outlet connecting piece, and the flange plate having at least a first intermediate layer which is arranged, relative to the holding force F, between the mounting layer and the holding layer. Here, the first intermediate layer is formed as a cavity structure, wherein the cavity structure has single- or multiple-part wall parts which extend in a direction parallel to the mounting layer and are arranged adjacent to one another, the wall parts having a width b1, measured in a direction parallel to the mounting layer, and having a heig…
