The lining panel comprises the face and the back surface, the side faces and lock elements as placed at the opposite ends of the panel long surrounding ?-like and surrounded ?-like bend elements for joining of neighboring panels. To compensate errors at making bended elements and thermal expansion of the panel in the ?-like bend element elastic elements are installed with threading to go at mounting to the ?-like bend element of the neighboring panel. |
