FIELD: shipbuilding; ship's structural members. SUBSTANCE: corrugations of structural members of ship's ceiling are passed through cuts in opposite beams or beyond boundaries of opposite beams; they have minimum rigidity in chain - sections of walls of structural members - corrugations of members in direction of action of loads in plane of beam walls. Width of corrugations does not exceed size of permissible deformation for structural members whose bands of skin are connected. Repair of such ceiling is effected by reverse separation of corrugations (after deformation) or by welding up the corrugations which get closed. EFFECT: reduction of expenses for repair of ship's ceiling. 3 cl, 6 dwg
