The board has a mantle-bar (3) with a part (7) corresponding to a slit (5). The part engages in a position of the bar in the slit mounted on a mounting core (2). The bar is braced in a position of the board mounted in a wall-base passage area due to the wall-unevenness over a part of its length between a wall (12) and the mounting core in such a manner that the bar is fixed in the wall-base-passage area. |
