DISPLACEMENT STRUCTURE METAL FRAMING Russian patent published in 2011 - IPC B63B3/00 

FIELD: transport.

SUBSTANCE: proposed framing comprises two systems of frame elements, each being jointed to outer plating and adequately oriented within its system. System of frame elements with lower bearing capacity is intended for reinforcing of frame elements orthogonal to said system with higher bearing capacity. For this, end faces of said reinforcing frame elements thrust against walls of reinforced frame elements. Free edges of frame elements are furnished with flanges. Reinforcing frame elements are made up of two extreme brackets and one central bracket arranged there between so that edges of extreme brackets facing the walls of reinforced frame elements are rigidly jointed therewith and have their height mating that of reinforced element minus mounting gap. Second edges of extreme brackets are rigidly jointed to outer plating. Third edges are furnished with flanges. Extreme bracket flange end faces edges are rigidly jointed to reinforced element flange edges facing the latter. One edge of central bracket is rigidly jointed with outer plating. Outer plating lateral edges are rigidly jointed with extreme bracket flange surface, while its free edge is furnished with the flange with its extreme edges rigidly jointed with extreme bracket flange surfaces. Edges of brackets furnished with flanges can feature zigzag shape. Bracket angle can be cut. Walls of brackets can be furnished with stiffness ribs. Bracket wall thickness may vary.

EFFECT: higher structural strength of ships or sea structures operated in ice conditions at high load on hull, reduced metal and labor input in mounting and adjustments.
