Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a structure for the coordinated arrangement of a vertical trough-shaped bulkhead and an internal bulkhead. Background Technology

[0002] In the cargo holds of some liquid cargo ships, vertical trough-shaped transverse bulkheads and vertical trough-shaped longitudinal bulkheads are often installed. The top and bottom plates of the vertical trough-shaped bulkheads and the top plates of the bottom plates are the places where stress is relatively large and stress concentration is likely to occur.

[0003] When the top and bottom bulkheads are arranged to cross the web of the vertical transverse (longitudinal) slotted bulkhead or are too close to the intersection of the web and the panel of the vertical transverse (longitudinal) slotted bulkhead, that is, when the vertical slotted bulkhead is arranged close to the top bulkhead (bottom bulkhead), it means that the reinforcement of the web of the vertical transverse (longitudinal) slotted bulkhead on the back of the top and bottom plates of the top and bottom plates is arranged to cross or close to the top and bottom bulkheads.

[0004] Cross-arrangement or close-to-close arrangement often appears in the design of trough-shaped bulkheads. Such arrangement is not only inconvenient to construct, but also causes stress concentration problems on the bottom pier top plate and the top pier bottom plate. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a structure for the coordinated arrangement of vertical trough-shaped bulkhead and internal bulkhead.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A vertical trough-shaped bulkhead and inner bulkhead arrangement structure is provided at the end of the vertical trough-shaped bulkhead; the vertical trough-shaped bulkhead includes a panel; a web is provided on the left and right sides of the panel, and the panel and the two webs form a groove; a surrounding plate for sealing the port of the groove is fixed at the end of the vertical trough-shaped bulkhead; the surrounding plates are distributed laterally; the surrounding plates are simultaneously fixed to the panel and the web; a bulkhead and a reinforcing plate are fixed on the surrounding plate; the bulkhead and the reinforcing plate are located on one side of the surrounding plate, and the panel and the web are located on the other side of the surrounding plate; both the reinforcing plate and the bulkhead are perpendicular to the surrounding plate; a reinforcing plate is provided on each side of the bulkhead, one reinforcing plate and the web located on the left side of the panel are in the same plane, and the other reinforcing plate and the web located on the right side of the panel are in the same plane; the bulkhead is perpendicular to the panel; the distance between the intersection of the bulkhead and the panel and the intersection of the web and the panel is d, where d is 300mm≤d≤b / 2, and b is the distance between the intersection of the web and the panel located on the left side of the panel and the intersection of the web and the panel located on the right side of the panel.

[0008] The cofferdam, bulkhead, and reinforcing plate are all located above the vertical trough-shaped bulkhead; the cofferdam is the top pier bottom plate, and the bulkhead is the top pier bulkhead.

[0009] The cofferdam, bulkhead, and reinforcing plate are all located below the vertical trough-shaped bulkhead; the cofferdam is the top plate of the bottom pier; the bulkhead is the bottom pier bulkhead.

[0010] The partition has through holes for people to pass through.

[0011] A side plate is fixed to each side of the partition.

[0012] The partition is perpendicular to the side panel.

[0013] The left and right ends of the reinforcing plate are fixedly connected to the two side plates respectively.

[0014] The inner end of the reinforcing plate is fixed to the surrounding plate, and the outer edge of the reinforcing plate includes a straight line segment and two arc-shaped line segments; the lower ends of the two arc-shaped line segments are respectively connected to the two ends of the straight line segment; the upper ends of the two arc-shaped line segments extend outward.

[0015] The partition has multiple reinforcing ribs; the reinforcing ribs are parallel to each other.

[0016] The reinforcing ribs are parallel to the surrounding panel.

[0017] The beneficial effects of this invention are as follows: By placing the bulkhead and panel at a specific location, the stress on the top pier bottom plate is minimized, reducing the risk of stress concentration at the intersection of the top pier bulkhead, top pier bottom plate, and channel-shaped bulkhead. This also reduces the increase in plate thickness on the top pier bottom plate, thus reducing the weight of the structural steel. Furthermore, the separate arrangement of the reinforcing plate and bulkhead in this invention greatly facilitates construction, offering the advantage of ease of construction. Attached Figure Description

[0018] Figure 1 This is a three-dimensional schematic diagram of Embodiment 1 of the present invention.

[0019] Figure 2 This is a top view of Embodiment 1 of the present invention.

[0020] Figure 3 This is a three-dimensional schematic diagram of Embodiment 2 of the present invention. Detailed Implementation

[0021] The present invention will be described more clearly and completely below with reference to two preferred embodiments and the accompanying drawings.

[0022] The vertical trough-shaped bulkhead and the inner bulkhead arrangement structure of the present invention can be located above the vertical trough-shaped bulkhead, that is, at the top of the vertical trough-shaped bulkhead; or it can be located below the vertical trough-shaped bulkhead, that is, at the bottom of the vertical trough-shaped bulkhead.

[0023] Embodiment 1 is located at the top of the vertical trough-shaped bulkhead; Embodiment 2 is located at the bottom of the vertical trough-shaped bulkhead. The only difference between Embodiment 1 and Embodiment 2 is their different positions on the vertical trough-shaped bulkhead; their structures are identical, therefore, the same reference numerals are used for the same components.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, a vertical trough-shaped bulkhead and an inner bulkhead are arranged in a cooperative manner, which is located at the end of the vertical trough-shaped bulkhead 10; the vertical trough-shaped bulkhead 10 includes a panel 11; a web plate 12 is provided on the left and right sides of the panel 11, and the panel 11 and the two web plates 12 form a groove.

[0026] The end of the vertical trough-shaped bulkhead 10 is fixed with a cofferdam 13 for sealing the port of the groove; the cofferdam 13 is distributed laterally; the cofferdam 13 is simultaneously fixed to the front panel 11 and the web 12.

[0027] A partition 14 and a reinforcing plate 15 are fixed on the enclosure 13; both the reinforcing plate 15 and the partition 14 are perpendicular to the enclosure 13.

[0028] The partition and reinforcing plate are located on one side of the enclosure, while the face plate and web plate are located on the other side. Specifically, the partition and reinforcing plate are located on the top of the enclosure, and the face plate and web plate are located on the bottom of the enclosure.

[0029] like Figure 1 As shown, the cofferdam 13, the bulkhead 14 and the reinforcing plate 15 are all located above the vertical trough-shaped bulkhead 10; the cofferdam 13 is the top pier bottom plate and the bulkhead 14 is the top pier bulkhead.

[0030] Each side of the partition 14 is provided with a reinforcing plate 15, one of which is located on the same plane as the web plate on the left side of the panel, and the other is located on the same plane as the web plate on the right side of the panel. Figure 1 In the image, only the reinforcing plate above one web is shown. To clearly show the structure of other components, the reinforcing plate above the other web is shown below. Figure 1 Not displayed.

[0031] The partition 14 is perpendicular to the panel 11.

[0032] The distance between the intersection of partition 14 and panel 11 and the intersection of web and panel is d, where d is 300mm≤d≤b / 2, and b is the distance between the intersection of web and panel on the left side of panel and the intersection of web and panel on the right side of panel.

[0033] The distance between the intersection of the partition and the panel and the intersection of the web and the panel on the left side of the panel is d; or, the distance between the intersection of the partition and the panel and the intersection of the web and the panel on the right side of the panel is d.

[0034] Figure 2 In one embodiment, the distance from the intersection of the partition 14 and the panel 11 to the intersection of the web and the panel on the right side of the panel is d. In another embodiment, the distance from the intersection of the partition and the panel to the intersection of the web and the panel on the left side of the panel is d. Both forms achieve the same technical effect.

[0035] The partition 14 has a through hole 21 for personnel to pass through.

[0036] A side plate 22 is fixedly connected to each side of the partition 14. Figure 1 In order to clearly show the structure between the two side plates, only one side plate is shown in the figure, and the other side plate is shown elsewhere. Figure 1 Not shown in the image.

[0037] The partition 14 is perpendicular to the side plate 22. The left and right ends of the reinforcing plate 15 are fixed to the two side plates 22 respectively.

[0038] The inner end of the reinforcing plate 15 is fixed to the surrounding plate 13. The outer edge of the reinforcing plate 15 includes a straight segment 31 and two arc-shaped segments 32. The lower ends of the two arc-shaped segments 32 are respectively connected to the two ends of the straight segment 31. The upper ends of the two arc-shaped segments 32 extend outward.

[0039] The partition 14 is provided with multiple reinforcing ribs 23; the reinforcing ribs 23 are parallel to each other. The reinforcing ribs 23 are parallel to the surrounding panel 13.

[0040] Extensive mechanical calculations and analyses have revealed that when the top pier diaphragm is located within a range of 300mm from the center of the panel to the intersection of the web and the panel, the stress on the bottom plate of the top pier is minimized. This reduces the risk of stress concentration at the intersection of the top pier diaphragm, the bottom plate of the top pier, and the trough-shaped bulkhead, and also reduces the increase in plate thickness on the bottom plate of the top pier, which is beneficial for reducing the weight of the structural steel.

[0041] In this embodiment, the reinforcing plate and the partition are arranged separately, which greatly facilitates construction and has the advantage of convenient construction.

[0042] Example 2

[0043] The only difference between this embodiment and embodiment 1 is that they are located at different positions on the vertical trough-shaped bulkhead. Their structures are the same, so the same parts are referred to by the same reference numerals.

[0044] like Figure 3 As shown, the cofferdam 13, bulkhead 14, and reinforcing plate 15 are all located below the vertical trough-shaped bulkhead 10; the cofferdam 13 is the top plate of the bottom pier; the bulkhead 14 is the bottom pier bulkhead. Figure 3 The side panels are not shown. Figure 3Only one reinforcing plate 15 is shown in the image. To clearly show the structure of other components, another reinforcing plate is shown in the image. Figure 3 Not displayed.

[0045] The partition and reinforcing plate are located on one side of the enclosure, while the face plate and web plate are located on the other side. Specifically, the partition and reinforcing plate are located below the enclosure, while the face plate and web plate are located above the enclosure.

[0046] Since the other structures are the same as in Example 1, they will not be described again here.

[0047] Extensive mechanical calculations and analyses have revealed that when the bottom pier diaphragm is located within 300mm of the intersection of the web and the panel, the stress on the top plate of the bottom pier is minimized. This reduces the risk of stress concentration at the intersection of the bottom pier diaphragm, the top plate of the bottom pier, and the trough-shaped bulkhead, and also reduces the increase in plate thickness on the top plate of the bottom pier, which is beneficial for reducing the weight of the structural steel.

[0048] In this embodiment, the reinforcing plate and the partition are arranged separately, which greatly facilitates construction and has the advantage of convenient construction.

[0049] 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.
