Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a bulkhead support structure and a ship. Background Technology

[0002] Ship cargo bulkheads generally include two types: flat bulkheads and channel bulkheads. Channel bulkheads, which are corrugated and made of pressed steel plates, are widely used in various large cargo ships. To achieve better structural strength, channel bulkheads are usually equipped with a base support structure. When the channel bulkhead is compressed by cargo, the load is transferred to and distributed to the hull through the base support structure, thus providing strong support for the cargo in the cargo hold.

[0003] Traditional floor support structures typically consist of side plates on both sides, with supporting ribs welded between the two side plates. This structure occupies a significant amount of cargo hold space and is not conducive to internal construction during the building process, thus making it less practical. Summary of the Invention

[0004] The purpose of this invention is to provide a bulkhead support structure and a ship that can reduce its own weight, increase cargo hold volume, and improve ship construction efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A bulkhead support structure for supporting a top plate, the top plate for supporting the trough-shaped bulkhead, comprising:

[0007] A side panel, which abuts against the top panel vertically and is vertically aligned with the first panel of the trough-shaped bulkhead;

[0008] The support assembly includes a support beam, the two ends of which are connected to the sidewalls of the hull along the length direction. The support beam abuts against the top plate vertically and is vertically positioned opposite the second panel of the trough-shaped bulkhead.

[0009] Preferably, the support assembly further includes a support side plate, one end of which is connected to the side upright plate along its length, and the other end of which is connected to the support crossbeam;

[0010] The supporting side plate, which is vertically adjacent to the trough-shaped bulkhead, abuts against the top plate.

[0011] Preferably, the support side plate has a weight-reducing groove.

[0012] Preferably, a support plate is provided on the side plate, and the support side plate abuts against the support plate vertically.

[0013] Preferably, the side plate is provided with a plurality of stiffening ribs (11) evenly spaced along the length direction.

[0014] Preferably, the bulkhead support structure further includes a truss assembly disposed on the side upright and abutting against the support side plate and the support beam in a vertical direction.

[0015] Preferably, the truss assembly includes a plurality of spaced-apart first trusses, which are connected to the side uprights and abut against the support beams vertically.

[0016] Preferably, the first truss includes a web and a flange that are fixedly connected, and the web and the flange are arranged at an angle.

[0017] The web plate is welded to the side plate, and the wing plate is welded vertically to the supporting beam.

[0018] Preferably, the truss assembly further includes a plurality of spaced second trusses, which are welded to the side plate perpendicularly to the first trusses.

[0019] The ship includes a trough-shaped bulkhead, a top plate, and the aforementioned bulkhead support structure. The trough-shaped bulkhead, the top plate, and the side uprights are arranged vertically in sequence, and the side uprights abut against the bottom plate vertically.

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

[0021] The bulkhead support structure provided by this invention is used to support the top plate of a trough-shaped bulkhead. This bulkhead support structure includes side uprights and support components. Since the side uprights and support beams abut against the top plate vertically, and the two ends of the support beams are connected to the hull sidewalls along their length, the side uprights and support beams can reliably support the top plate. Because the side uprights are vertically aligned with the first panel of the trough-shaped bulkhead, and the support beams are vertically aligned with the second panel of the trough-shaped bulkhead, this bulkhead support structure can provide targeted support for the upper trough-shaped bulkhead, preventing the first and second panels of the trough-shaped bulkhead from impacting the top plate. Stress concentration at the corresponding locations causes structural damage, thus ensuring the safety of the top plate and the trough-shaped bulkhead. Compared with conventional trough-shaped bulkhead support structures, this bulkhead support structure only has a side plate on one side. By adjusting the position of the side plate and the support beam, it can provide strong support for the upper trough-shaped bulkhead while reducing the amount of structural materials used and the weight of the ship. At the same time, the elimination of the other side plate frees up construction space, which is conducive to improving the construction environment and thus improving the ship's construction efficiency. In addition, the elimination of the other side plate also frees up some cargo hold space and expands the cargo hold volume.

[0022] The ship provided by this invention includes a trough-shaped bulkhead, a top plate, and the aforementioned bulkhead support structure. The trough-shaped bulkhead, top plate, and side uprights are arranged vertically in sequence, and the side uprights abut against the bottom plate of the hull vertically, thereby forming a stable and reliable support for the top plate and the bulkhead support structure. At the same time, since the bulkhead support structure only has a side upright on one side, it reduces the amount of structural materials used, lightens the ship's weight, improves the construction space, and greatly enhances the ship's construction efficiency.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0034] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0037] like Figure 1 and Figure 2 As shown, the present invention provides a bulkhead support structure for supporting a top plate 100, which in turn supports a channel-shaped bulkhead 200. The bulkhead support structure includes a side plate 1 and a support assembly 2. The side plate 1 abuts against the top plate 100 vertically and is vertically aligned with the first panel 210 of the channel-shaped bulkhead 200. The support assembly 2 includes a support beam 21, the two ends of which are connected to the sidewalls of the hull along their length. The support beam 21 abuts against the top plate 100 vertically and is vertically aligned with the second panel 220 of the channel-shaped bulkhead 200.

[0038] In this embodiment, since the side uprights 1 and the supporting beams 21 abut against the top plate 100 vertically, and the two ends of the supporting beams 21 are connected to the sidewalls of the hull along their length, the side uprights 1 and the supporting beams 21 can reliably support the top plate 100. Since the side uprights 1 are vertically aligned with the first panel 210 of the trough-shaped bulkhead 200, and the supporting beams 21 are vertically aligned with the second panel 220 of the trough-shaped bulkhead 200, this bulkhead support structure can provide targeted support for the upper trough-shaped bulkhead 200, thus preventing the first panel 210 and the second panel 220 of the trough-shaped bulkhead 200 from being misaligned with the corresponding positions on the top plate 100. The placement of the top plate 100 causes stress concentration and damage, thus ensuring the safety of the top plate 100 and the trough-shaped bulkhead 200. Compared with the conventional trough-shaped bulkhead support structure, this bulkhead support structure only has a side plate 1 on one side. By adjusting the position of the side plate 1 and the support beam 21, it can provide strong support for the upper trough-shaped bulkhead 200 while reducing the amount of structural materials and the weight of the ship. At the same time, the elimination of the other side plate 1 frees up construction space, which is conducive to improving the construction environment and thus improving the construction efficiency of the ship. In addition, the elimination of the other side plate 1 also frees up some cargo hold space and expands the volume of the cargo hold.

[0039] Specifically, such as Figure 2 As shown, the trough-shaped bulkhead 200 is a commonly used bulkhead structure on ships, with a wave-shaped cross-section to enhance its structural strength. The trough-shaped bulkhead 200 consists of a first panel 210, a second panel 220, and an adjacent plate 230. The first panel 210 and the second panel 220 are arranged in parallel, and the adjacent plate 230 connects the two, thus forming a wave-shaped structure. The trough-shaped bulkhead 200 is vertically arranged on the horizontal top plate 100, thereby dividing the interior of the ship's hold into several cargo hold spaces. The side uprights 1 are arranged corresponding to the first panel 210 of the trough-shaped bulkhead 200, and the supporting beams 21 are arranged corresponding to the second panel 220, with the supporting beams 21 parallel to the side uprights 1.

[0040] like Figures 1 to 3As shown, the support assembly 2 also includes a support side plate 22. One end of the support side plate 22 is connected to the side upright plate 1 along its length, and the other end is connected to the support beam 21. The support side plate 22 abuts against the top plate 100 along its vertical direction, directly opposite the adjacent plate 230 of the trough-shaped bulkhead 200. Therefore, the support side plate 22 can support the top plate 100 to prevent the adjacent plate 230 of the trough-shaped bulkhead 200 from causing local stress concentration on the top plate 100 and damaging the top plate 100. Specifically, one end of the support side plate 22 is welded to the side upright plate 1, and the other end of the support side plate 22 is welded to the support beam 21. The specific shape and structure of the support side plate 22 can be set according to the actual situation, as long as it can ensure a tight connection with the support beam 21 and the side upright plate 1 and provide stable support for the top plate 100. It is understandable that the support side plate 22 is positioned directly opposite the adjacent plate 230, and therefore the support side plate 22 is parallel to the adjacent plate 230 to ensure that it provides more stable and powerful support for the adjacent plate 230.

[0041] In this embodiment, the cross-section of the supporting beam 21 is a T-shaped structure, which consists of mutually perpendicular horizontal plates and vertical plates, wherein the horizontal plates are parallel to the horizontal direction and the vertical plates are parallel to the vertical direction; the end of the supporting side plate 22 near the supporting beam 21 is a right-angle structure, so it can be welded to fit the horizontal plates and vertical plates.

[0042] To further reduce the weight of the bulkhead support structure, such as Figure 3 As shown, a weight-reducing groove is provided on the supporting side plate 22. Simultaneously, to strengthen the support of the supporting side plate 22 for the upper top plate 100 and the connection strength between the supporting side plate 22 and the side upright plate 1, as shown... Figure 3 As shown, a support plate 12 is provided on the side plate 1, and a support side plate 22 abuts against the support plate 12 vertically; specifically, the support plate 12 is welded to the side plate 1, and the top of the support plate 12 is welded to the support side plate 22.

[0043] like Figure 4 As shown, multiple stiffening ribs 11 are evenly spaced along the length of the side upright plate 1. The stiffening ribs 11 can enhance the structural strength and stability of the side upright plate 1 and prevent the cargo in the cargo hold space on both sides from squeezing the side upright plate 1 and causing damage to the side upright plate 1.

[0044] To improve the support performance for the upper roof 100 and the trough-shaped bulkhead 200, such as Figure 4 As shown, the bulkhead support structure also includes a truss assembly 3, which is disposed on the side upright plate 1 and abuts against the support side plate 22 and the support beam 21 in a vertical direction.

[0045] Specifically, such as Figure 1 and Figure 4As shown, the truss assembly 3 includes a plurality of spaced first trusses 31. The first trusses 31 are connected to the side upright plate 1 and abut against the support beam 21 in a vertical direction. In this embodiment, the first trusses 31 are welded to the side upright plate 1 and their length direction is parallel to the vertical direction. One end of the first trusses 31 is welded to the support beam 21 and the other end is welded to the bottom plate 300.

[0046] The specific structure of the first truss 31 can be configured according to actual conditions, as long as it can provide strong support for the upper supporting beam 21. For example, the first truss 31 includes a web and a flange that are fixedly connected. The web and flange are set at an angle. The web is welded to the side upright plate 1, and the flange is welded vertically to the supporting beam 21. In this embodiment, the web and flange are welded vertically. The cross-section of the first truss 31 is T-shaped, and the flange is parallel to the length direction of the supporting beam 21. Therefore, the welding of the flange to the supporting beam 21 increases the connection area between the first truss 31 and the supporting beam 21, thereby enhancing the strength and stability of the connection between the two.

[0047] Furthermore, such as Figure 4 As shown, the truss assembly 3 also includes a plurality of spaced second trusses 32, which are welded perpendicularly to the first trusses 31 to the side uprights 1. In this embodiment, the second trusses 32 are cuboid structures, welded to the side uprights 1, and their length direction is parallel to the horizontal direction. The second trusses 32 are disposed between two adjacent first trusses 31, and both ends of the second trusses 32 are welded to the first trusses 31 on both sides respectively. The second trusses 32 can improve the rigidity of the first trusses 31 and the side uprights 1 to ensure stable support for the top plate 100 and the trough-shaped bulkhead 200.

[0048] In this embodiment, the first truss 31 is welded vertically to the side plate 1, and multiple first trusses 31 are spaced apart. The second truss 32 is welded horizontally to the side plate 1, and multiple second trusses 32 are spaced apart. The cross-sectional area of ​​the stiffening rib 11 is much smaller than that of the first truss 31 and the second truss 32. The stiffening rib 11 is disposed between two adjacent first trusses 31 to avoid interference with the first trusses 31. The second truss 32 is welded to the stiffening rib 11.

[0049] This embodiment also provides a ship, which includes a trough-shaped bulkhead 200, a top plate 100, and the aforementioned bulkhead support structure. The trough-shaped bulkhead 200, the top plate 100, and the side uprights 1 are arranged vertically in sequence, and the side uprights 1 abut against the bottom plate 300 vertically. In this embodiment, the trough-shaped bulkhead 200, the top plate 100, and the side uprights 1 are arranged vertically in sequence, and the side uprights 1 abut against the bottom plate 300 of the hull, thereby forming a stable and reliable support for the top plate 100 and the bulkhead support structure. At the same time, since the bulkhead support structure only has a side upright 1 on one side, it reduces the amount of structural materials used, lightens the ship's weight, improves the construction space, and greatly enhances the ship's construction efficiency. Specifically, the bottom plate 300 is the outer plate of the bottom of the hull, and the side uprights 1, the first truss 31, and the stiffening ribs 11 are all welded vertically to the bottom plate 300.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
