Abstract
Hull structure made of composite material that includes a hull with high thickness “single skin” monocoque plating without reinforcements and an internal stiffening structure (1) formed by a deck (2), two opposing transverse bulkheads (3) and more cradle-shaped load-bearing elements (5) to support components or machinery intended to be housed on board said hull structure. Advantageously, the above-mentioned cradle-shaped load-bearing elements (5) are supported at the respective internal portions of said opposite transverse bulkheads (3) only at their opposite head ends (5b).
Claims16
A hull structure based on suitably reinforced plastic material, wherein said hull structure extends from bow to stern in a longitudinal direction (X-X) and includes a “single skin” monocoque plating and an internal stiffening structure (1), wherein said internal stiffening structure (1) comprises:
- at least one deck (2);
- at least two opposite transverse bulkheads (3) extended vertically and in a transverse direction (Y-Y) orthogonal to said longitudinal direction (X-X) and to said at least one deck (2);
- and
- one or more cradle-shaped load-bearing elements (5) to support machinery intended to be housed on said hull structure, said one or more cradle-shaped load-bearing elements (5) extending in said longitudinal direction (X-X) between opposite head ends (5b),
- wherein:
- said one or more cradle-shaped load-bearing elements (5) are supported:
- only at said opposite head ends (5b) of said cradle-shaped load-bearing elements (5) and
- only from respective first portions of said opposite transverse bulkheads (3), and
- said at least one deck extends in said longitudinal direction between opposed head ends of said at least one deck from said two opposite transverse bulkheads (3), said deck (2) resulting to be intercostal between said opposite transverse bulkheads (3).
A hull structure based on suitably reinforced plastic material, wherein said hull structure extends from bow to stern in a longitudinal direction (X-X) and includes a “single skin” monocoque plating and an internal stiffening structure (1), wherein said internal stiffening structure (1) comprises:
- at least one deck (2);
- at least two opposite transverse bulkheads (3) extended vertically and in a transverse direction (Y-Y) orthogonal to said longitudinal direction (X-X) and to said at least one deck (2);
- and
- one or more cradle-shaped load-bearing elements (5) to support machinery intended to be housed on said hull structure, said one or more cradle-shaped load-bearing elements (5) extending in said longitudinal direction (X-X) between opposite head ends (5b),
- wherein said one or more cradle-shaped load-bearing elements (5) are supported:
- only at said opposite head ends (5b) of said cradle-shaped load-bearing elements (5) and
- only from respective first portions of said opposite transverse bulkheads (3), wherein said transverse bulkheads (3) comprise stiffening ribs (4) extending axially in a prevailing vertical direction (Z-Z).
A hull structure based on suitably reinforced plastic material, wherein said hull structure extends from bow to stern in a longitudinal direction (X-X) and includes a “single skin” monocoque plating and an internal stiffening structure (1), wherein said internal stiffening structure (1) comprises:
- at least one deck (2);
- at least two opposite transverse bulkheads (3) extended vertically and in a transverse direction (Y-Y) orthogonal to said longitudinal direction (X-X) and to said at least one deck (2);
- and
- one or more cradle-shaped load-bearing elements (5) to support machinery intended to be housed on said hull structure, said one or more cradle-shaped load-bearing elements (5) extending in said longitudinal direction (X-X) between opposite head ends (5b),
- wherein said one or more cradle-shaped load-bearing elements (5) are supported:
- only at said opposite head ends (5b) of said cradle-shaped load-bearing elements (5) and
- only from respective first portions of said opposite transverse bulkheads (3), wherein:
- said at least one deck (2) is jointed to said two opposite transverse bulkheads (3) in correspondence with respective contact areas (6) extended in said transverse direction (Y-Y) along said transverse bulkheads (3);
- and
- in each of said transverse bulkheads (3) a transversal portion(S) is identified which incorporates the respective contact area (6) and is free of any stiffening rib.
A hull structure based on suitably reinforced plastic material, wherein said hull structure extends from bow to stern in a longitudinal direction (X-X) and includes a “single skin” monocoque plating and an internal stiffening structure (1), wherein said internal stiffening structure (1) comprises:
- at least one deck (2);
- at least two opposite transverse bulkheads (3) extended vertically and in a transverse direction (Y-Y) orthogonal to said longitudinal direction (X-X) and to said at least one deck (2);
- and
- one or more cradle-shaped load-bearing elements (5) to support machinery intended to be housed on said hull structure, said one or more cradle-shaped load-bearing elements (5) extending in said longitudinal direction (X-X) between opposite head ends (5b),
- wherein said one or more cradle-shaped load-bearing elements (5) are supported:
- only at said opposite head ends (5b) of said cradle-shaped load-bearing elements (5) and
- only from respective first portions of said opposite transverse bulkheads (3), wherein said one or more cradle-shaped load-bearing elements (5) comprise a plurality of distinct and parallel elements in said transverse direction (Y-Y).
