Claim 3

The assembly defined in claim 1 further comprising a sealing layer between said flanges.

Claim 4

The assembly defined in claim 1 wherein said planks define in the region of said hooks a space opening outwardly in a longitudinally extending groove running the lengths of said planks, a sealing mass of permanently elastic material received in said space, said assembly further comprising a wedge driven into said groove for externally closing said space.

Claim 5

The assembly defined in claim 3 wherein said wedge has one flank having an arcuate curvature centered on said axis and another flank confronting a flank of said groove, said wedge having a cross section corresponding substantially to the cross section of said groove.

Claim 6

The assembly defined in claim 4 wherein the flanks of said groove and the flanks of said wedge are provided with mutually engaging sawtooth formations preventing outward movement of said wedge after it is driven into said groove.

Claim 7

The assembly defined in claim 1 wherein said hooks define between said planks a space extending the length of said planks, one of said planks having bores opening into said space, said assembly further comprising a sealing mass injected into said space through said bores.

Claim 8

The assembly defined in claim 1 wherein the plank formed with said inner hook is provided with an attachment flange coaxial with its arcuate flange, said assembly further comprising transverse ribs secured to said flanks by bolts through said attachment flange, said attachment flange extending in a direction opposite to the direction in which the arcuate flange of the plank provided with the inner hook extends.

Claim 9

The assembly defined in claim 7 wherein each of said transverse ribs is formed with a channel configuration and a substantially U-cross section of semicircular profile to enable the attachment of said attachment flange thereto in various angular positions.

Claim 10

The assembly defined in claim 1 further comprising deck profiles connected to one of said planks with a joint corresponding to that between said planks, said deck profiles being provided with formations enabling a deck covering to be applied thereto.

Claim 11

The assembly defined in claim 9 wherein said one of said planks is provided with an inwardly extending flange and said deck plank is secured to said flange by a transition piece provided with a respective hook and bolted to said flange.

Claim 12

A planking assembly for a ship's hull, comprising a pair of doubly curved longitudinally extending planks, one of said planks being formed with a longitudinally extending outer hook, the other of said planks being formed with a longitudinally extending inner hook engaging in said hook over the lengths of said planks and only in line contact therewith, said hooks interengaging with angular play about a pivot axis of said inner hook, and means for holding said hooks against one another in said line contact whereby a traction-type junction is formed between said planks over the entire lengths thereof, said planks being of uniform cross section over their entire lengths, each plank being formed with an arcuate flange of circular curvature centered on said axis spaced from each hook, said flanges being juxtaposed with one another, said assembly further comprising bolt means in line with said hooks interconnecting said flanges and drawing same together to hold said hooks in line engagement with one another, the plank formed with said inner hook being provided with an attachment flange coaxial with its arcuate flange, said assembly further comprising transverse ribs secured to said flanks by bolts through said attachment flange, said attachment flange extending in a direction opposite to the direction in which the arcuate flange of the plank provided with the inner hook extends each of said transverse ribs being formed with a channel configuration and a substantially U-cross section of semicircular profile to enable the attachment of said attachment flange thereto in various angular positions, said transverse ribs having inwardly reinforced ends of said channels adapted to receive a bulk head between them.

Claim 13

A planking assembly for a ship's hull, comprising a pair of doubly curved longitudinally extending planks, one of said planks being formed with a longitudinally extending outer hook, the other of said planks being formed with a longitudinally extending inner hook engaging in said hook over the lengths of said planks and only in line contact therewith, said hooks interengaging with angular play about a pivot axis of said inner hook, and means for holding said hooks against one another in said line contact whereby a traction-type junction is formed between said planks over the entire lengths thereof, said planks being of uniform cross section over their entire lengths, each plank being formed with an arcuate flange of circular curvature centered on said axis spaced from each hook, said flanges being juxtaposed with one another, said assembly further comprising bolt means in line with said hooks interconnecting said flanges and drawing same together to hold said hooks in line engagement with one another, the plank formed with said inner hook being provided with an attachment flange coaxial with its arcuate flange, said assembly further comprising transverse ribs secured to said flanks by bolts through said attachment flange, said attachment flange extending in a direction opposite to the direction in which the arcuate flange of the plank provided with the inner hook extends each of said transverse ribs being formed with a channel configuration and a substantially U-cross section of semicircular profile to enable the attachment of said attachment flange thereto in various angular positions, said transverse ribs having inwardly reinforced ends of said channels adapted to receive a bulk head between them.

Claim 14

A planking assembly for a ship's hull, comprising a pair of doubly curved longitudinally extending planks, one of said planks being formed with a longitudinally extending outer hook, the other of said planks being formed with a longitudinally extending inner hook engaging in said outer hook over the lengths of said planks and only inline contact therewith, said hooks interengaging with angular play about a pivot axis of said innner hook, and means for holding said hooks against one another in said line contact whereby a traction-type junction is formed between said planks over the entire lengths thereof, said planks being of uniform cross section over their entire lengths, each plank being formed with an arcuate flange of circular curvature centered on said axis spaced from each hook, said flanges being juxtaposed with one another, said assembly further comprising bolt means in line with said hooks interconnecting said flanges and drawing same together to hold said hooks in line engagement with one another, said assembly further comprising deck profiles connected to one of said planks with a joint corresponding to that between said plates, said deck profiles being provided with formations enabling a deck covering to be applied thereto, said one of said planks being provided with a rib having a hook directly engageable with a hook of said deck profile and a further rib extending substantially at 90° to the first mentioned rib thereabove.

Claim 15

A planking assembly for a ship's hull, comprising a pair of doubly curved longitudinally extending planks, one of said planks being formed with a longitudinally extending outer hook, the other of said planks being formed with a longitudinally extending inner hook engaging in said outer hook over the lengths of said planks and only inline contact therewith, said hooks interengaging with angular play about a pivot axis of said innner hook, and means for holding said hooks against one another in said line contact whereby a traction-type junction is formed between said planks over the entire lengths thereof, said planks being of uniform cross section over their entire lengths, each plank being formed with an arcuate flange of circular curvature centered on said axis spaced from each hook, said flanges being juxtaposed with one another, said assembly further comprising bolt means in line with said hooks interconnecting said flanges and drawing same together to hold said hooks in line engagement with one another, said assembly further comprising deck profiles connected to one of said planks with a joint corresponding to that between said plates, said deck profiles being provided with formations enabling a deck covering to be applied thereto, said one of said planks being provided with a rib having a hook directly engageable with a hook of said deck profile and a further rib extending substantially at 90° to the first mentioned rib thereabove.
