ABSTRACT:
A method for manufacturing an internal structure of a coach body having a self-supporting outer structure includes winding an inner covering layer on a winding core, attaching channel segments to a ceiling wall and insulation segments to corner regions, attaching heating fabric sheets to a floor wall and to side walls, attaching metal rails extending longitudinally to the floor wall and the side walls, filling between the rails with insulating foam, winding an outer covering layer to form an internal structure. After the setting of the resin impregnated layers, the internal structure is removed from the winding core and cut open longitudinally at the floor wall. The internal structure is elastically deformed and inserted into an outer structure. The walls of the internal structure are moved by a tensioning device into engagement with the outer structure and the internal structure is provisionally attached to the outer structure with fasteners.
