The partition gap is provided between the upper-building side outer plate and the bulwark plate, that is, the upper-building side outer plate is not connected to the bulwark plate, so that the upper-building side outer plate does not transmit force to the bulwark plate, the bulwark plate does not participate in the total longitudinal bending, that is, the bulwark plate does not bear the total longitudinal bending stress, and the stress of the bulwark plate structure is reduced overall. Therefore, there is no need to deliberately strengthen the bulwark plate, which can reduce the construction consumables of the bulwark plate and the total weight of the ship, while avoiding the problem of increased construction difficulty caused by adding reinforcement ribs to the bulwark plate.

Description

Technical Field

[0001] The present application relates to the technical field of ship structures, and in particular to a transition structure between a superstructure side outer plate and a bulwark plate. Background Art

[0002] Generally speaking, if Figure 1 As shown, the superstructure 02 of the main deck 01 of the conventional ship is connected to the superstructure side outer plate 02 on one side close to the bulwark plate 03. In the transition structure between the superstructure side outer plate 02 and the bulwark plate 03, the upper edge structural member (flat iron or steel section, etc.) of the bulwark plate 03 extends continuously to the top side of the superstructure side outer plate 02, so that the rear bulwark plate 03 and the superstructure side outer plate 02 structure form an integrated whole. However, this transition structure has certain drawbacks: when the hull is subjected to a hogging or sagging bending moment, the longitudinal structure of the superstructure 02 suddenly disappears at the starting or ending end of the superstructure 02, causing a sudden increase in the total longitudinal bending stress of the longitudinal components at the end wall of the superstructure 02. Because the superstructure side shell 02 is connected to the bulwark plate 03, the bulwark plate 03 (including the upper edge structural members of the bulwark plate) actually contributes to the total longitudinal strength. At the same time, because the upper edge structural members of the bulwark plate are farthest from the neutral axis, the local stress of the bulwark plate 03 and the upper edge structural members at this location is too high, making it easy to damage. To overcome this drawback, existing ship designs require structural reinforcement of the bulwark plate 03. Strengthening the bulwark plate 03 generally involves increasing the plate thickness of the bulwark plate 03 or increasing the size and number of stiffeners. In addition to increasing material consumption and weight, this approach also increases the difficulty of welding the stiffeners due to the limited space in the transition area.

[0012] Optionally, the filling component includes an appearance membrane and an internal support assembly, the internal support assembly is fixed on the main deck, the appearance membrane is covered on the outside of the internal support assembly, the appearance membrane and the internal support assembly both have elastic deformation capabilities, based on the elastic deformation capability of the internal support assembly, the membrane adapts to changes in the width of the partition gap, and based on the elastic deformation capability of the appearance membrane, the membrane itself is always kept taut; the appearance membrane is supported by the internal support assembly so that the outer surface of the appearance membrane is always flush with the outer wall surface of the upper side outer plate and the bulwark plate.

[0013] Optionally, the appearance membrane includes a flexible diaphragm and a plurality of tension springs, the two ends of the tension springs being respectively connected to two opposite sides of the flexible diaphragm, so that the appearance membrane constitutes a circular structure with elastic deformation capability and can be sleeved on the outside of the inner support component.

[0014] Optionally, the internal support assembly includes a main support rod, an ejection spring and a support plate, the bottom of the main support rod is fixed on the main deck, and a support plate is provided on both sides.

[0028] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0029] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0031] like Figure 1 As shown, the superstructure 02 of the main deck 01 of the conventional ship is connected to the superstructure side outer plate 02 on one side close to the bulwark plate 03. In the transition structure between the superstructure side outer plate 02 and the bulwark plate 03, the upper edge structural member (flat iron or steel section, etc.) of the bulwark plate 03 extends continuously to the top side of the superstructure side outer plate 02, so that the rear bulwark plate 03 and the superstructure side outer plate 02 structure form an integrated whole. However, this transition structure has certain drawbacks: when the hull is subjected to a hogging or sagging bending moment, the longitudinal structure of the superstructure 02 suddenly disappears at the starting or ending end of the superstructure 02, causing a sudden increase in the total longitudinal bending stress of the longitudinal components at the end wall of the superstructure 02. Because the superstructure side shell 02 is connected to the bulwark plate 03, the bulwark plate 03 (including the upper edge structural members of the bulwark plate) actually contributes to the total longitudinal strength. At the same time, because the upper edge structural members of the bulwark plate are farthest from the neutral axis, the local stress of the bulwark plate 03 and the upper edge structural members at this location is too high, making it easy to damage. To overcome this drawback, existing ship designs require structural reinforcement of the bulwark plate 03. Strengthening the bulwark plate 03 generally involves increasing the plate thickness of the bulwark plate 03 or increasing the size and number of stiffeners. In addition to increasing material consumption and weight, this approach also increases the difficulty of welding the stiffeners due to the limited space in the transition area.

[0032] In order to overcome the above technical problems, Figure 2-3As shown, this embodiment provides a transition structure between a superstructure side shell and a bulwark plate, comprising an upper-structure side shell 4 and a bulwark plate 3. The bulwark plate 3 is provided on the side of the main deck 1. The upper-structure side shell 4 is connected to a side of the superstructure 2 close to the bulwark plate 3. A partition gap 5 is formed between the upper-structure side shell 4 and the bulwark plate 3.

[0033] Based on the transition structure between the superstructure side shell and the bulwark panels of this embodiment, a partition gap 5 is provided between the upper side shell 4 and the bulwark panels 3. That is, the upper side shell 4 and the bulwark panels 3 are not connected. As a result, the upper side shell 4 does not transmit force to the bulwark panels 3. The bulwark panels 3 do not participate in the total longitudinal bending, that is, the bulwark panels 3 do not bear the total longitudinal bending stress. This generally reduces the stress in the structure of the bulwark panels 3, and therefore does not need to specifically strengthen the bulwark panels 3. This can reduce the construction consumables of the bulwark panels 3 and the total weight of the ship. At the same time, the problem of increased construction difficulty caused by adding reinforcement ribs to the bulwark panels 3 is avoided.

[0034] In one embodiment, the width of the upper side outer plate 4 is between 1 and 3 rib distances.

[0035] Specifically, the rib pitch is the distance between two ribs on the hull. Controlling the width of the upper shear plate 4 to between 1 and 3 rib pitches prevents the upper shear plate 4 from being too wide. This prevents the upper shear plate 4 from being subjected to excessive stress on the side away from the superstructure 2, thereby ensuring the durability of the upper shear plate 4.

[0036] In one embodiment, the width of the upper side outer plate 4 is two rib distances.

[0037] Specifically, the upper side shell plating 4 includes a plate body connected to the main deck 1 and a horizontal beam plate perpendicular to the upper edge of the plate body. The inventors' calculations and analysis show that the wider the width of the upper side shell plating 4, the greater the total longitudinal bending stress borne by the plate body; the smaller the width of the upper side shell plating 4, the greater the total longitudinal bending stress borne by the horizontal beam plate. Setting the width of the upper side shell plating 4 to two rib distances can simultaneously control the total longitudinal bending stress borne by the plate body of the upper side shell plating 4 and the horizontal beam plate at its upper edge to a smaller range, avoiding the problem of either the plate body or the horizontal beam plate being subjected to excessive total longitudinal bending stress.

[0038] In one embodiment, the upper edge of the upper building side outer plate 4 is an arc-shaped edge that gradually decreases from the superstructure 2 side to the partition gap 5 side, and the side of the upper building side outer plate 4 close to the bulwark plate 3 is at the same height as the bulwark plate 3.

[0039] The upper edge of the upper side outer plate 4 can be in the form of an arc, an elliptical arc, or a curve. The use of an arc transition connection can make the upper side outer plate 4 and the superstructure 2 beautifully connected, while reducing the concentrated stress at the connection between the upper side outer plate 4 and the superstructure 2.

[0040] In one embodiment, the width of the partition gap 5 is greater than 5 cm.

[0041] Due to the provision of the partition gap 5, the total longitudinal bending stress of the upper side shell plating 4 will not be transmitted to the bulwark plating 3. When the hull is subjected to a hogging or sagging bending moment, a slight relative deformation will occur between the upper side shell plating 4 and the bulwark plating 3. By controlling the partition gap 5 to be greater than 5 cm, sufficient deformation space can be reserved, thereby avoiding the problem of stress transmission after the upper side shell plating 4 and the bulwark plating 3 deform and contact.

[0042] In one embodiment, a filling member 6 is provided on the main deck 1 and is located in the partition gap 5. The partition gap 5 is filled by the filling member 6, so that the outer wall surface of the upper side outer plate 4, the filling member 6 and the bulwark plate 3 are connected to form a complete continuous surface.

[0043] Specifically, the filling member 6 is provided to fill the partition gap 5. From the outside of the hull, the existence of the partition gap 5 is not visible, thereby avoiding the problem of the partition gap 5 affecting the hull appearance. At the same time, the filling of the filling member 6 can prevent objects on the main deck 1 from falling into the water through the partition gap 5.

[0044] In one embodiment, the filling member 6 is an elastic member that is elastically stretchable.

[0045] Setting the filling member 6 as an elastic and resilient elastic member can enable the filling member 6 to always maintain a complete seal on the partition gap 5, and at the same time can adapt to changes in the width of the partition gap 5, avoiding a rigid connection between the upper side outer plate 4 and the bulwark plate 3.

[0046] In one embodiment, the filling member 6 includes an exterior membrane 61 and an interior support assembly 62. The interior support assembly 62 is fixed to the main deck 1, and the exterior membrane 61 is covered on the outside of the interior support assembly 62. Both the exterior membrane 61 and the interior support assembly 62 have elastic deformation capabilities. Based on the elastic deformation capability of the interior support assembly 62, the filling member 6 includes an exterior membrane 61 and an interior support assembly 62. The interior support assembly 62 adapts to changes in the width of the partition gap 5, and based on the elastic deformation capability of the exterior membrane 61, the filling member 6 includes an exterior membrane 61 and an interior support assembly 62. The exterior membrane 61 is supported by the interior support assembly 62 so that the outer surface of the exterior membrane 61 is always flush with the outer wall surfaces of the upper side outer plate 4 and the bulwark plate 3.

[0047] Specifically, the exterior membrane 61 is an elastically stretchable membrane. When in tension, its outer surface remains flat. Therefore, as long as the exterior membrane 61 remains in tension, its outer surface can be consistently connected to the outer surfaces of the upper side shell plating 4 and the bulwark panels 3 on either side. Therefore, this solution supports the exterior membrane 61 with elastically deformable internal support components 62. These components adapt to changes in the width of the partition gap 5 through their own elastic deformation, while maintaining tension on the exterior membrane 61, ensuring that the outer surfaces of the upper side shell plating 4, the infill member 6, and the bulwark panels 3 are consistently connected to form a complete, continuous surface.

[0048] In one embodiment, the appearance membrane 61 includes a flexible diaphragm 611 and a plurality of tension springs 612, and the two ends of the tension springs 612 are respectively connected to two opposite sides of the flexible diaphragm 611, so that the appearance membrane 61 constitutes a circular structure with elastic deformation ability and can be mounted on the outside of the internal support component 62.

[0049] The flexible diaphragm 611 and tension spring 612 are combined. The tension spring 612 has a large deformation capacity, providing greater flexibility for the deformation of the exterior membrane 61. This allows for a wider range of deformation while ensuring that the flexible diaphragm 611 remains taut. In practical applications, the tension spring 612 should be located on the side facing the main deck 1, allowing the flexible diaphragm 611 to be positioned outboard to maintain alignment with the hull's outer wall.

[0050] In one embodiment, the internal support assembly 62 includes a main support rod 621, an ejection spring 622 and a support plate 623. The bottom of the main support rod 621 is fixed to the main deck 1, and a support plate 623 is provided on both sides. The main support rod 621 and the support plate 623 are connected by the ejection spring 622. The ejection spring 622 is used to open the support plates 623 on both sides, and the support plates 623 are used to open the appearance membrane 61, so that the outer wall surface of the appearance membrane 61 can be connected with the outer wall surface of the upper side outer plate 4 and the bulwark plate 3.

[0051] Reference Figure 7 During installation, the main support rod 621 is fixed to the main deck 1 through the bulwark plate 3 and the upper side shell plate 4. Under the elastic force of the ejection spring 622, the support plates 623 on both sides are pushed toward the bulwark plate 3 and the upper side shell plate 4 respectively, so that the appearance film 61 sleeved outside the two support plates 623 can be seamlessly connected with the bulwark plate 3 and the upper side shell plate 4.

[0052] Specifically, when the partition gap 5 is reduced, the support plates 623 on both sides are squeezed and moved closer to each other, the ejection spring 622 is compressed, and the tensioning spring 612 contracts, pulling the flexible diaphragm 611 to keep it taut; conversely, when the partition gap 5 is expanded, under the action of the ejection spring 622, the support plates 623 on both sides are pushed open, the tensioning spring 612 is extended, and the flexible diaphragm 611 is pulled to keep it taut.
