Description

Technical Field

[0001] This application relates to the field of marine technology, and in particular to a double-hull support assembly for ships. Background Technology

[0002] As the core load-bearing structure of the ship's hull, the double-hull support assembly mainly transmits loads and enhances overall rigidity through the synergistic effect of longitudinal skeletons, ribs, and stiffeners.

[0003] However, in practical applications, ship double-hull support components face several challenges. First, some structural connections are prone to insufficient fatigue strength under alternating loads, requiring local structural reinforcement, which can lead to material and cost waste. Second, the arrangement of longitudinal components results in concentrated openings in the transverse support structure, reducing the effective load-bearing area and compromising overall structural strength, often necessitating additional material thickness. Third, under external loads, the stability of some plate-like structures is easily affected; existing reinforcement methods offer limited improvement in stability, often requiring the addition of auxiliary components or thicker plates. Finally, multi-component connection nodes are subject to multi-directional constraints, demanding stringent manufacturing and assembly precision, inevitably leading to rework due to errors in actual production. Summary of the Invention

[0004] The purpose of this invention is to provide a ship double-hull support assembly that can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] As one aspect of this application, a ship double-hull support assembly is provided, comprising:

[0007] A rib plate, which connects the outer shell plate and the inner shell plate; a through hole is formed on the rib plate;

[0008] Multiple hull longitudinal ribs are provided on the hull plate along the height direction of the ship and each hull longitudinal rib extends along the length direction of the ship; the spacing between adjacent hull longitudinal ribs is equal; each hull longitudinal rib passes through the through hole and is connected to the rib plate;

[0009] Multiple inner shell longitudinal ribs are provided on the inner shell plate along the height direction of the ship, and each inner shell longitudinal rib extends along the length direction of the ship; the spacing between adjacent inner shell longitudinal ribs is equal; the inner shell longitudinal ribs are opposite to and staggered with the outer shell longitudinal ribs; each inner shell longitudinal rib passes through the through hole and is connected to the rib plate.

[0010] A reinforcing rib is arranged perpendicular to the rib plate, the outer shell plate, and the inner shell plate, and is connected to the rib plate.

[0011] Preferably, the end of the reinforcing rib near the inner shell plate is connected to the longitudinal rib of the inner shell.

[0012] Preferably, the end of the reinforcing rib near the outer shell plate is a wedge-shaped end, and the height of the wedge-shaped end gradually decreases as it approaches the outer shell plate; the space between the rib plate and the wedge-shaped end of the reinforcing rib is filled by a fillet weld.

[0013] Preferably, the gap between the outer shell plate and the wedge-shaped end of the reinforcing rib is 15mm to 50mm.

[0014] Preferably, the end of the reinforcing rib near the inner shell plate is provided with a chamfer, and the chamfer is provided to bypass the through hole on the rib plate.

[0015] Preferably, the inner shell longitudinal rib is at least one of T-shaped profile, bulb flat steel, and angle steel.

[0016] Preferably, the reinforcing rib is welded and fixed perpendicularly to the rib plate.

[0017] Preferably, the reinforcing rib is one or more of flat iron, bulb flat steel, and angle steel.

[0018] Preferably, the outer shell plate and the inner shell plate are located at the hull side.

[0019] Preferably, the outer shell plate and the inner shell plate are located at the bottom of the ship.

[0020] The beneficial effects of this application are as follows:

[0021] In this application, the outer shell longitudinal ribs and the inner shell longitudinal ribs are staggered, and the height of the through holes through the ribs is staggered, which reduces the concentrated loss of the shear section of the ribs, significantly improves their shear resistance, and avoids the problem of insufficient local strength. At the same time, the staggered arrangement makes the welding points between the outer shell longitudinal ribs and the inner shell longitudinal ribs and the stiffeners more dispersed, reducing the influence of stress concentration and welding residual stress.

Figure 2 for Figure 1 Schematic diagram of the structure of section AA in the middle. Figure 3 for Figure 1 A structural schematic diagram of the BB cross-section. (See diagram below.) Figures 1 to 3 As shown in the figure, the X direction is the width direction of the ship, the Y direction is the height direction of the ship, and the Z direction is the length direction of the ship.

[0032] This embodiment provides a double-hull support assembly for a ship, including: a rib plate 100, an outer shell plate 200, an inner shell plate 300, multiple outer shell longitudinal ribs 400, multiple inner shell longitudinal ribs 500, and reinforcing ribs 600; the rib plate 100 connects the outer shell plate 200 and the inner shell plate 300; a through hole 101 is formed on the rib plate 100; multiple outer shell longitudinal ribs 400 are arranged on the outer shell plate 200 along the ship's height direction, and each outer shell longitudinal rib 400 extends along the ship's length direction; the spacing between adjacent outer shell longitudinal ribs 400 is equal; each outer shell longitudinal rib 400 passes through the through hole 101. The through hole 101 is connected to the rib plate 100; a plurality of inner shell longitudinal ribs 500 are arranged on the inner shell plate 300 along the height direction of the ship, and each inner shell longitudinal rib 500 extends along the length direction of the ship; the spacing between adjacent inner shell longitudinal ribs 500 is equal; the inner shell longitudinal ribs 500 are opposite to and staggered with the outer shell longitudinal ribs 400; each inner shell longitudinal rib 500 passes through the through hole 101 and is connected to the rib plate 100; the reinforcing rib 600 is arranged perpendicular to the rib plate 100, the outer shell plate 200 and the inner shell plate 300, and is connected to the rib plate 100.

[0033] In this embodiment, the outer shell plate 200 and the inner shell plate 300 are located at the hull. The outer shell plate 200 serves as the outermost shell of the ship and is provided with multiple outer shell longitudinal ribs 400. The outer shell longitudinal ribs 400 are typically arranged horizontally along the Y direction (ship height direction) and extend along the Z direction (ship length direction). The outer shell longitudinal ribs 400 can be arranged at equal intervals or nearly equal intervals; no specific limitation is made here. The inner shell plate 300 serves as the shell located inside the outer shell plate 200 and is provided with multiple inner shell longitudinal ribs 500. The inner shell longitudinal ribs 500 are also typically arranged horizontally along the Y direction (ship height direction) and extend along the Z direction (ship length direction). The inner shell longitudinal ribs 500 can be arranged at equal intervals or nearly equal intervals; no specific limitation is made here. It should also be noted that the spacing between each outer shell longitudinal rib 400 and the spacing between each inner shell longitudinal rib 500 can generally be set to be equal. In some embodiments, the spacing between each outer shell longitudinal rib 400 and the spacing between each inner shell longitudinal rib 500 can also be set to be close. No specific limitation is made here.

[0034] In this embodiment, the outer shell longitudinal ribs 400 and the inner shell longitudinal ribs 500 are arranged opposite each other and staggered, avoiding the overlap of the height of the through holes of the outer shell longitudinal ribs 400 and the inner shell longitudinal ribs 500 in the rib plate, thus reducing stress superposition. Specifically, the height of each outer shell longitudinal rib 400 and the height of each inner shell longitudinal rib 500 are different along the Y direction (i.e., the ship's height direction). Furthermore, there is a certain height difference between each outer shell longitudinal rib 400 and the inner shell longitudinal rib 500 with a similar height, thus the outer shell longitudinal ribs 400 and the inner shell longitudinal ribs 500 are arranged in a staggered manner.

[0035] As an optional embodiment, the outer shell longitudinal ribs 400 and the inner shell longitudinal ribs 500 are arranged opposite each other and staggered, with each inner shell longitudinal rib 500 arranged higher than each outer shell longitudinal rib 400, such as... Figure 1 As shown. In this embodiment, the outer shell longitudinal ribs 400 and the inner shell longitudinal ribs 500 do not need to be at the same horizontal height, increasing the flexibility of their arrangement. Along the Y direction (i.e., the ship's height direction), the outer shell longitudinal ribs 400 and inner shell longitudinal ribs 500 at the upper end typically bear less load, while those at the lower end bear more load. Here, the height of the lowest outer shell longitudinal rib 400 can be adjusted as needed to reduce the distance between it and the platform 900 below, thus appropriately reducing the seawater pressure it receives. At the same time, the distance between the highest outer shell longitudinal rib 400 and the deck 700 (or the deck longitudinal ribs 701 installed on the deck 700) is increased, appropriately increasing the load on the highest outer shell longitudinal rib 400. This ensures that the two lowest outer shell longitudinal ribs 400 bear equal stress, facilitating the use of the same specifications while avoiding waste. The same applies to the highest outer shell longitudinal ribs 400.

[0036] As an optional embodiment, the outer shell longitudinal ribs 400 and the inner shell longitudinal ribs 500 are arranged opposite each other and staggered, with each inner shell longitudinal rib 500 arranged lower than each outer shell longitudinal rib 400 (not shown in the figure). In this embodiment, the outer shell longitudinal ribs 400 and the inner shell longitudinal ribs 500 do not need to be at the same horizontal height, increasing the flexibility in the arrangement of the outer shell longitudinal ribs 400 and the inner shell longitudinal ribs 500. Along the Y-direction (i.e., the ship's height direction), the upper outer shell longitudinals 400 and inner shell longitudinals 500 typically bear less load, while the lower outer shell longitudinals 400 and inner shell longitudinals 500 bear more load. Here, the height of the lowermost inner shell longitudinal 500 can be adjusted as needed to reduce the distance between the lowermost inner shell longitudinal 500 and the platform 900 below, thus appropriately reducing the seawater pressure it shares. At the same time, the distance between the uppermost inner shell longitudinal 500 and the deck 700 is increased, appropriately increasing the load on the uppermost inner shell longitudinal 500. This ensures that the two lowermost inner shell longitudinals 500 bear equal stress, facilitating the use of the same specifications while avoiding waste. The same applies to the uppermost inner shell longitudinals 500.

[0037] In this embodiment, a rib 100 is provided between the outer shell plate 200 and the inner shell plate 300. The outer side of the rib 100 is connected to the outer shell plate 200, and the inner side of the rib 100 is connected to the inner shell plate 300. Through holes 101 are provided on both the outer and inner sides of the rib 100, allowing the outer shell longitudinal rib 400 and the inner shell longitudinal rib 500 to pass through. The rib 100 is connected to both the outer shell longitudinal rib 400 and the inner shell longitudinal rib 500 at the through holes 101. The through holes 101 on the outer side and the through holes 101 on the inner side of the rib 100 are staggered along the Y direction (i.e., the ship's height direction), so that the through holes 101 on the outer side of the rib 100 are aligned with the height of the outer shell longitudinal rib 400, and the through holes 101 on the inner side of the rib 100 are aligned with the height of the inner shell longitudinal rib 500. In this embodiment, the through holes 101 on the outer side of the rib 100 and the through holes 101 on the inner side of the rib 100 are staggered, which reduces the weakening effect of the through holes 101 on the strength of the rib 100 and improves the shear resistance of the rib 100, thereby increasing structural safety or reducing the weight of the rib 100.

[0038] Regarding the through holes 101 on the inner side of the rib plate 100, these through holes 101 are generally larger than the size of the inner shell longitudinal rib 500. Conversely, regarding the through holes 101 on the outer side of the rib plate 100, these through holes 101 are generally larger than the size of the outer shell longitudinal rib 400. It should also be noted that the reinforcing ribs 600 are generally close to the through holes 101 on the outer side of the rib plate 100, which can provide some reinforcement to the through holes 101 and reduce the stress level at the through holes 101.

[0039] It should be noted that the outer side of the rib plate 100 and the outer shell plate 200, the outer side of the rib plate 100 and the outer shell longitudinal rib 400, the inner side of the rib plate 100 and the inner shell plate 300, and the inner side of the rib plate 100 and the inner shell longitudinal rib 500 can all be fixed by welding.

[0040] Regarding the reinforcing ribs 600 provided on the rib plate 100, the reinforcing ribs 600 are arranged horizontally. The reinforcing ribs 600 can generally be one or more of flat iron, bulb flat steel, and angle steel. It should be noted that the reinforcing ribs 600 and the rib plate 100 can generally be welded and fixed perpendicularly.

[0041] In one embodiment, the rib plate 100 is a single, flat, transverse member with several (e.g., horizontal, vertical, or diagonal) reinforcing ribs 600 arranged on its surface. These reinforcing ribs 600, together with the edges of the rib plate 100 (e.g., the connecting edges with the outer shell plate 200 and the inner shell plate 300), enclose the rib plate 100 into multiple independent small areas, each of which is a plate grid. In this embodiment, the plate grid of the rib plate 100 has a connection with the outer shell longitudinal rib 400 on its short side near the outer shell plate 200. The welded connection with the outer shell longitudinal rib 400 extends into the interior of the plate grid, rather than being limited to the boundary, which improves the structural stability of the plate grid and reduces the amount of stability reinforcement structure used and the thickness of the rib plate.

[0042] In one embodiment, the end of the reinforcing rib 600 near the inner shell plate 300 is connected to the inner shell longitudinal rib 500. Conversely, the end of the reinforcing rib 600 near the outer shell plate 200 is separate from the outer shell longitudinal rib 400; in other words, the end of the reinforcing rib 600 near the outer shell plate 200 is not connected to the outer shell longitudinal rib 400. This arrangement of the outer shell longitudinal rib 400 reduces the number of stress concentration points, lowers the stress level, significantly improves fatigue life, and saves considerable effort in constructing fatigue-strengthening structures for longitudinal ribs. Furthermore, the fact that the reinforcing rib 600 is not connected to the outer shell longitudinal rib 400 reduces the workload of assembly, welding, and grinding, thus improving production efficiency.

[0043] One side of the reinforcing rib 600 is welded to the rib plate 100, and the other side of the reinforcing rib 600 is welded to the inner shell longitudinal rib 500. The reinforcing rib 600 can be fixed by welding in two vertical directions, avoiding rigid constraints when welding three or more sides to multiple components at the same time, thus avoiding the occurrence of jamming. It is easy to install, and the manufacturing precision requirements of related components are relatively low, which improves the product qualification rate and greatly reduces rework waste.

[0044] In this embodiment, the end of the reinforcing rib 600 near the outer shell plate 200 is offset from the through hole 101 of the outer shell longitudinal rib 400 in the Y direction (i.e., the ship's height direction). The end of the reinforcing rib 600 near the inner shell plate 300 is arranged at the same height as the inner shell longitudinal rib 500 in the Y direction (i.e., the ship's height direction). Specifically, along the Y direction (i.e., the ship's height direction), the reinforcing rib 600 may be slightly higher than or slightly lower than the through hole 101 on the outer side of the rib plate 100.

[0045] In one embodiment, the end of the reinforcing rib 600 near the outer shell plate 200 is a wedge-shaped end 601, and the height of the wedge-shaped end 601 gradually decreases as it approaches the outer shell plate 200; the space between the rib plate 100 and the wedge-shaped end 601 of the reinforcing rib 600 is filled by a fillet weld. The gap between the outer shell plate 200 and the wedge-shaped end 601 of the reinforcing rib 600 is 15mm to 50mm.

[0046] The end of the reinforcing rib 600 near the inner shell plate 300 is connected to the inner shell longitudinal rib 500. The end of the reinforcing rib 600 near the outer shell plate 200 is provided with a wedge-shaped end so that the height of the reinforcing rib 600 gradually decreases as it approaches the outer shell plate 200. At the end of the reinforcing rib 600 closest to the outer shell plate 200 (which can also be said to be the end of the wedge-shaped end), only a small amount of height is left to facilitate the filling of the fillet weld between the reinforcing rib 600 and the rib plate 100.

[0047] In one embodiment, the reinforcing rib 600 has a chamfer 602 at one end near the inner shell plate 300, and the chamfer 602 is provided to bypass the through hole 101 on the rib plate 100.

[0048] Regarding the connection between the reinforcing rib 600 and the inner shell longitudinal rib 500, the reinforcing rib located at the opening of the through hole 101 is provided with a chamfer 602. The shape of the chamfer 602 can typically be an arc or a combination of an arc and a straight line. By providing the chamfer 602, the connection between the reinforcing rib 600 and the rib plate 100 avoids the location of the through hole opened near the inner side of the rib plate 100.

[0049] In one embodiment, the inner shell longitudinal ribs can be T-shaped profiles, bulb flats, or angle steel.

[0050] When the inner shell longitudinal rib 500 is a T-shaped profile, the reinforcing rib 600 is aligned with the web of the inner shell longitudinal rib 500.

[0051] When the inner shell longitudinal rib 500 is made of bulb flat steel or angle steel, the web of the reinforcing rib 600 can be offset by a few millimeters in the direction of the inner shell longitudinal rib 500 panel, based on the height of the web of the inner shell longitudinal rib 500, so as to fill the fillet weld.

[0052] Here is a brief introduction to the structure of the inner shell longitudinal rib 500. The web of the inner shell longitudinal rib 500 is a flat plate structure perpendicular or nearly perpendicular to the inner shell plate 300, extending continuously along the length of the inner shell longitudinal rib 500. The height of the web of the inner shell longitudinal rib 500 is much greater than its thickness. The web of the inner shell longitudinal rib 500 is the main load-bearing structure resisting bending deformation. The face plate of the inner shell longitudinal rib 500 is perpendicular to the web of the inner shell longitudinal rib 500 and parallel to the inner shell plate at its location, but is not necessarily horizontally arranged. The face plate and the web of the inner shell longitudinal rib 500 together form a T-shaped or L-shaped cross-sectional shape. The width of the face plate of the inner shell longitudinal rib 500 is usually greater than the thickness of the web of the inner shell longitudinal rib 500, and extends synchronously with the web of the inner shell longitudinal rib 500 along its length. The panels of the inner shell longitudinal rib 500 primarily bear the tensile and compressive stresses generated during bending. By dispersing stress through a large transverse cross-sectional area, the bending resistance of the inner shell longitudinal rib 500 is improved. The panels of the inner shell longitudinal rib 500 are a key structure for resisting longitudinal tension or compression.

[0053] In one embodiment of this application, the outer shell plate 200 and the inner shell plate 300 are located at the bottom of the ship. The bottom outer plate 820 and the bottom inner plate 810 are arranged sequentially from bottom to top along the Y direction (i.e., the ship's height direction), and the bottom outer plate 820 and bottom inner plate 810 are arranged horizontally. In this embodiment, the bottom outer plate 820 serves as the outermost shell of the ship. The bottom outer plate 820 is provided with multiple bottom outer longitudinal ribs 830, which are typically arranged horizontally along the X direction (i.e., the ship's width direction), and each bottom outer longitudinal rib 830 extends along the Z direction (i.e., the ship's length direction). The bottom outer longitudinal ribs 830 can be arranged at equal intervals or nearly equal intervals; no specific limitation is made here. The inner bottom plate 810, serving as the shell inside the outer bottom plate 820, is provided with multiple inner bottom longitudinal ribs 840. These ribs are horizontally arranged along the X direction (i.e., the ship's width direction) and extend horizontally along the Z direction (i.e., the ship's length direction). The inner bottom longitudinal ribs 840 can be arranged at equal or nearly equal intervals; no specific limitation is made here. Furthermore, it should be noted that the spacing between the outer bottom longitudinal ribs 830 and the spacing between the inner bottom longitudinal ribs 840 can generally be set to be equal. In some embodiments, the spacing between the outer bottom longitudinal ribs 830 and the inner bottom longitudinal ribs 840 can also be set to be close; no specific limitation is made here.

[0054] In this embodiment, the bottom outer longitudinal ribs 830 and the bottom inner longitudinal ribs 840 are arranged opposite each other and staggered, avoiding overlap in the height of the bottom outer longitudinal ribs 830 and the bottom inner longitudinal ribs 840 at the through holes of the rib plate 100, thus reducing stress superposition. Specifically, the positions of each bottom outer longitudinal rib 830 and each bottom inner longitudinal rib 840 are different along the X direction (i.e., the ship's width direction). Furthermore, there is a certain distance difference between each bottom outer longitudinal rib 830 and the bottom inner longitudinal rib 840 that is close to it, thus the bottom outer longitudinal ribs 830 and the bottom inner longitudinal ribs 840 are arranged in a staggered manner.

[0055] A rib 100 is provided between the bottom outer plate 820 and the bottom inner plate 810. The outer side of the rib 100 is connected to the bottom outer plate 820, and the inner side of the rib 100 is connected to the bottom inner plate 810. Through holes 101 are provided on both the outer and inner sides of the rib 100, allowing the bottom outer longitudinal rib 830 and the bottom inner longitudinal rib 840 to pass through. The rib 100 is connected to the bottom outer longitudinal rib 830 and the bottom inner longitudinal rib 840 at the through holes 101. The through holes 101 on the outer side and the through holes 101 on the inner side of the rib 100 are staggered along the X direction (i.e., the ship's width direction) so that the through holes 101 on the outer side of the rib 100 mate with the position of the bottom outer longitudinal rib 830, and the through holes 101 on the inner side of the rib 100 mate with the position of the bottom inner longitudinal rib 840. In this embodiment, the through holes 101 on the outer side of the rib 100 and the through holes 101 on the inner side of the rib 100 are staggered, which reduces the weakening effect of the through holes 101 on the strength of the rib 100 and improves the shear resistance of the rib 100, thereby increasing structural safety or reducing the weight of the rib 100.

[0056] The end of the reinforcing rib 600 near the bottom inner plate 810 is connected to the bottom inner longitudinal rib 840. Conversely, the end of the reinforcing rib 600 near the bottom outer plate 820 is separate from the bottom outer longitudinal rib 830; in other words, the end of the reinforcing rib 600 near the bottom outer plate 820 is not connected to the bottom outer longitudinal rib 830. This arrangement of the bottom outer longitudinal rib 830 reduces the number of stress concentration points, lowers the stress level, significantly improves fatigue life, and saves a considerable amount of effort in constructing fatigue-strengthening structures for longitudinal ribs. Furthermore, the fact that the reinforcing rib 600 is not connected to the bottom outer longitudinal rib 830 reduces the workload of assembly, welding, and grinding, thus improving production efficiency. Components involved in this embodiment that are the same as those in the aforementioned embodiments will not be repeated here.
