Through the second cell type wall 2 that sets up the variable cross section, can utilize this variable cross section structure to satisfy the support intensity of whole cell type wall subassembly, directly replace the structure of upper wall mound and lower wall mound, simplified the manufacturing step, reduced the manufacturing degree of difficulty, the stress concentration condition of no large tracts of land has reduced the potential safety hazard, and second cell type wall 2 need not to cut apart out independent cabin structure for the hold of cabin is held greatly, and cargo carrying capacity is greatly promoted.
In this embodiment, the first trough-shaped wall 1 is formed by connecting a plurality of first trough-shaped sections, each of the first trough-shaped sections includes a first panel 11 and first webs 12 disposed on two opposite sides of the first panel 11, the first panel 11 and two of the first webs 12 form a first wall trough having an opening, two adjacent first trough-shaped sections share one of the first webs 12, and the openings of the first wall troughs of the two adjacent first trough-shaped sections are disposed opposite to each other.
Further, two first webs 12 of each first groove-shaped section are arranged at a first included angle, and the first included angle is larger than 90 degrees. Preferably, two first webs 12 are symmetrically arranged along the center line of the first panel 11, so that the first wall groove forms an isosceles trapezoid groove structure. The isosceles trapezoid-shaped first groove-shaped section can enable the first groove-shaped wall 1 to bear force uniformly on the whole, and local stress concentration is prevented.
In this embodiment, the second trough-shaped wall 2 is formed by connecting a plurality of second trough-shaped sections, each of the second trough-shaped sections includes a second panel 21 and second webs 22 disposed on two opposite sides of the second panel 21, the second panel 21 and two of the second webs 22 form a second wall trough having an opening, two adjacent second trough-shaped sections share one of the second webs 22, and the openings of the second wall troughs of two adjacent second trough-shaped sections are disposed opposite to each other, and each of the second panels 21 is inclined by the first panel 11 toward a side away from the corresponding first wall trough. The structure enables the second groove-shaped wall 2 to form a structure with a variable section, the sectional area of one end, connected with the first groove-shaped wall 1, of the second groove-shaped wall 2 is equal to that of the first groove-shaped wall 1, and the sectional area of the second groove-shaped wall 2 is gradually increased along with the distance from the first groove-shaped wall 1, so that the second groove-shaped wall 2 with the variable section can reduce the structural stress at the joint with the first groove-shaped wall 1, can also increase the supporting strength of the whole second groove-shaped wall 2, and can completely replace a wall pier with a closed cabin structure.
In a preferred embodiment of the present invention, the intersection line of the second panel 21 and the inner bottom panel 200 is a first intersection line 3, and the first intersection line 3 is parallel to the first panel 11; the intersection line of the second panel 21 and the main deck 100 is a second intersection line 4, and the second intersection line 4 is parallel to the first panel 11.
In this embodiment, a vertical distance between a projection line of the first panel 11 on the inner bottom plate 200 and the first intersection line 3 is a first distance, and the first distance is not greater than a groove depth of the first wall groove; the vertical distance between the projection line of the first panel 11 on the main deck 100 and the second intersection line 4 is a second distance, and the second distance is not greater than the groove depth of the first wall groove.
The above design is mainly to prevent the length of the end of the second panel 21 connected to the inner bottom plate 200 or the main deck 100 (i.e. the length of the first intersection line 3 and the second intersection line 4) from being less than half of the length of the end of the second panel 21 connected to the first panel 11, thereby ensuring that the second groove-shaped wall 2 with variable cross-section has sufficient load-bearing capacity.
Further, the first distance is 300 mm-500 mm, and the second distance is 200 mm-500 mm. The design mainly embodies that the maximum sectional area of the second trough-shaped wall 2 at the upper end of the first trough-shaped wall 1 can be designed to be smaller than the maximum sectional area of the second trough-shaped wall 2 at the lower end of the first trough-shaped wall 1, because the second trough-shaped wall 2 at the lower end bears more pressure after the cabin is actually loaded with goods, and the pressure borne by the second trough-shaped wall 2 at the upper end is relatively smaller, the second trough-shaped wall 2 at different positions is designed according to the actually borne pressure, the use of steel can be reduced to the maximum extent, the cost is reduced, and meanwhile, the weight of the ship is reduced.
In another preferred embodiment of the present invention, the first web 12 and the second web 22 are located on the same plane, the second web 22 has a trapezoidal structure, an intersection line between the second web 22 and the inner bottom plate 200 is a third intersection line 5, and a length of the third intersection line 5 is not greater than 2 times a groove depth of the first wall groove. The above design makes it possible to make the maximum sectional area of the second channel wall 2 not more than 2 times the sectional area of the first channel wall 1, so that the second channel wall 2 occupies less cabin volume while ensuring the necessary support strength.
Further, the second panel 21 and the second web 22 of the second channel wall 2 at the lower end of the first channel wall 1 meet the inner bottom panel 200 at a point.
Further, the height of the first channel wall 1 is not less than four times the height of the second channel wall 2.
In particular, the height of the first channel wall 1 is five times the height of the second channel wall 2.

1. the variable cross-section groove-shaped wall assembly only comprises simple wall plates, an independent cabin structure does not need to be separated, the space of the cabin does not need to be occupied, the cabin capacity of the cabin is effectively increased, and the economic benefit of ship use is increased.
2. The variable cross-section groove-shaped wall component is directly connected with the inner bottom plate 200 through the variable cross-section groove-shaped wall, an independent small cabin is not generated, and the corresponding cost of ship equipment such as ventilation and the like is saved compared with that of a common ship.
3. The variable cross-section groove-shaped wall component does not need to be connected with a wall pier, so that stress concentration at the joint is eliminated, and the structure is effectively prevented from being damaged.
4. The variable cross-section groove-shaped wall component is simple in structure and small in steel amount. Due to the fact that the variable-section groove-shaped wall is simple in structure, construction costs of welding, polishing, paint coating and the like in ship manufacturing construction can be saved.
