FIELD: transport.
SUBSTANCE: invention relates to ship building, particularly, to ship hulls made from composite polymer materials. Ship hull comprises three-layer skin with inner and outer layer, foam plastic filler arranged there between to make central layer wit reinforcing trapezoidal ribs, and frame beams of U-like section with walls and flange. Reinforcing trapezoidal ribs are integrated into integral corrugated element with different-height crimps. Aforesaid beam is made by crimp of larger height and width while three-layer skin inner layer bending around said crimp to thicken beam wall and flange.
EFFECT: strong joint between ship skin and frame set beam.
