The invention relates to a flange plate 1 for a manifold 2.2 of an exhaust-gas system 2.1 for internal combustion engines 2, which flange plate can be fixed via at least one holding means 2.3 to an exhaust-gas outlet connecting piece 2.4 of the internal combustion engine 2 by means of a first outer layer 1.1, formed as a mounting layer 1.1, which can be placed at least partially directly or indirectly against the exhaust-gas outlet connecting piece 2.4 via a seal 3, and said flange plate can be applied to the holding means 2.3 by means of a second outer layer 1.2, formed as a holding layer 1.2, in order to generate a holding force F, acting at a right angle to the mounting layer 1.1, for sealingly placing the mounting layer 1.1 against the exhaust-gas outlet connecting piece 2.4, and said flange plate having at least a first intermediate layer 1.3 which is arranged, relative to the holding force F, between the mounting layer 1.1 and the holding layer 1.2. Here, the first intermediate layer 1.3 is formed as a cavity structure, wherein the cavity structure 1.3 has single- or multiple-part wall parts 1.4a, 1.4b which extend in a direction parallel to the mounting layer 1.1 and are arranged adjacent to one another, said wall parts having a width b1, measured in a direction parallel to the mounting layer 1.1, and having a height h1, measured in a direction at a right angle to the mounting layer 1.1, where h1 > b1, wherein the different wall parts 1.4a, 1.4b delimit a plurality of cavities 1.5 which are open towards the mounting layer 1.1 or towards the holding layer 1.2 or, together with the mounting layer 1.1 and the holding layer 1.2, delimit an open-ended channel 1.5. |
