Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a hull girder end structure that eliminates the need for elbow plates. Background Technology

[0002] Hull girder structures are widely used as major supporting components in ship structure design, especially in the superstructure and deck planes. As the main supporting components of deck beams / longitudinals, girder structures need to meet certain web height requirements to ensure the strength and rigidity of the deck surface.

[0003] According to structural design specifications, elbow plates or locally enlarged end structures must be installed at the ends of all trusses. However, in superstructure areas with limited floor height, it is necessary to consider not only the layout of ventilation ducts and cables, but also the space requirements for the outfitting within the cabins to enclose the hull structure. The elbow plates at the truss ends are vertically distributed and located below the trusses. These elbow plates at the truss ends often lead to problems such as the inability to arrange pipes and cables close to the bulkheads, or insufficient cabin height due to the need for ample space for internal outfitting panels. Summary of the Invention

[0004] In order to overcome the above-mentioned defects in the existing technology, the present invention provides a hull girder end structure that eliminates the need for elbow plates.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] An elbow-plate-free hull girder end structure includes a girder connected to the hull structure, the girder being a T-shaped member; the hull structure includes a first bulkhead and a second bulkhead fixed below the deck plate, both the girder and the second bulkhead being vertically fixed to the first bulkhead, the girder and the second bulkhead being respectively located on both sides of the first bulkhead; the web of the girder and the second bulkhead are located in the same plane; the second bulkhead is fixed with vertical stiffeners; no elbow plate is provided at the connection between the girder and the first bulkhead; the second bulkhead is fixed with a first panel transition plate, a second panel transition plate, and a web transition plate; both the first panel transition plate and the second panel transition plate are flush with the panel of the girder; the first panel transition plate and the second panel transition plate are respectively located on both sides of the second bulkhead; one end of the first panel transition plate is fixed to the first bulkhead, and the other end of the first panel transition plate is fixed to the vertical stiffener on the second bulkhead closest to the first bulkhead; the second panel transition plate is connected to the panel of the girder; the web transition plate is simultaneously fixed to the first bulkhead.

[0007] Furthermore, the thickness of the first panel transition plate, the thickness of the second panel transition plate, and the thickness of the truss panel are all the same.

[0008] Furthermore, the total width of the first panel transition plate and the second panel transition plate is not less than the width of the panel of the truss.

[0009] Furthermore, the length of the second panel transition plate is greater than the length of the first panel transition plate.

[0010] Furthermore, the length of the second panel transition plate is 15-20 mm longer than the length of the first panel transition plate.

[0011] Furthermore, the thickness of the web transition plate is the same as the thickness of the web of the truss.

[0012] Furthermore, the height of the web transition plate is greater than the height of the web of the truss.

[0013] Furthermore, the lower end of the web transition plate extends below the second panel transition plate.

[0014] Furthermore, the height of the portion of the web transition plate located below the second panel transition plate is not less than 50 mm.

[0015] Furthermore, the length of the web transition plate is not less than the height of the web of the truss.

[0016] The beneficial effects of this invention are as follows: The structural form of this invention not only meets the requirements of ship structure design specifications but also avoids the impact of the girder end elbows on the cabin layout, greatly freeing up usable cabin space. The structural form of this invention is simple, easy to construct, and does not increase additional construction costs. The structural form of this invention has strong applicability and can be used in various types of ships. Attached Figure Description

[0017] Figure 1 This is a top view of a preferred embodiment of the present invention.

[0018] Figure 2 for Figure 1 View from A in the middle. Detailed Implementation

[0019] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, a hull girder end structure without elbow plate includes a girder 10 connected to the hull structure. The girder is a T-shaped member. The girder 10 includes a web 11 and a face plate 12.

[0021] The hull structure includes a first bulkhead 21 and a second bulkhead 22 fixed below the deck plate 20. The girder 10 and the second bulkhead 22 are both vertically fixed to the first bulkhead 21. In this embodiment, the first bulkhead is a transverse bulkhead, the second bulkhead is a longitudinal bulkhead, and the girder 10 is a longitudinal girder.

[0022] The truss 10 and the second bulkhead 22 are respectively located on both sides of the first bulkhead 21; the web 11 of the truss and the second bulkhead 22 are located on the same plane; the second bulkhead 22 is fixed with vertical stiffeners 23.

[0023] No elbow plate is installed at the connection between truss 10 and the first bulkhead.

[0024] The second bulkhead 22 is fixedly provided with a first panel transition plate 31, a second panel transition plate 32 and a web transition plate 33.

[0025] The first panel transition plate 31 and the second panel transition plate 32 are both flush with the panel 12 of the truss; the first panel transition plate 31 and the second panel transition plate 32 are respectively located on both sides of the second bulkhead 22.

[0026] One end of the first panel transition plate 31 is fixed to the first bulkhead 21, and the other end of the first panel transition plate 31 is fixed to the vertical stiffener 23 on the second bulkhead that is closest to the first bulkhead.

[0027] The second panel transition plate 32 is connected to the panel 12 of the truss; the web transition plate 33 is simultaneously fixed to the first bulkhead 21.

[0028] The thickness of the first panel transition plate 31, the thickness of the second panel transition plate 32, and the thickness of the truss panel 12 are all the same.

[0029] The total width of the first panel transition plate 31 and the second panel transition plate 32 is not less than the width of the panel 12 of the truss.

[0030] The length of the second panel transition plate 32 is greater than the length of the first panel transition plate 31. The length of the second panel transition plate 32 is 15-20 mm longer than the length of the first panel transition plate 31. Figure 1 In this context, D represents the amount by which the length of the second panel transition plate 32 is greater than the length of the first panel transition plate 31, and D is 15 to 20 mm.

[0031] The thickness of the web transition plate 33 is the same as the thickness of the web plate 11 of the truss.

[0032] The height of the web transition plate 33 is greater than the height of the web plate 11 of the truss. The lower end of the web transition plate 33 extends below the second panel transition plate 32. The height E of the portion of the web transition plate 33 located below the second panel transition plate is not less than 50 mm, i.e., E ≥ 50 mm.

[0033] The length L of the web transition plate 33 is not less than the height H of the web plate 11 of the truss, that is, L≥H.

[0034] In this invention, the elbow plate between the end of the truss and the first bulkhead is eliminated. Along the direction of the hull truss, a reinforcing structure consisting of a first panel transition plate, a second panel transition plate, and a web transition plate is provided at the second bulkhead as an extension structure of the hull truss. This satisfies the strength and stiffness requirements of the hull truss end structure design.

[0035] By eliminating the elbow plates at the ends of the trusses, the space occupied by the elbow plates in the original design can be avoided, and almost no space in other areas will be occupied. The space under the trusses can be fully utilized for the arrangement of ventilation ducts and cables, as well as for the arrangement of other compartments.

[0036] The structural form of this invention can not only meet the requirements of ship structure design specifications, but also avoid the influence of the elbow plate at the end of the truss on the cabin layout, thus greatly freeing up the usable space of the cabin.

[0037] The present invention features a simple structure, is easy to construct, and does not incur additional construction costs. Furthermore, the structure of the present invention has strong applicability and can be used in various types of ships.

[0038] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
