Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a combined bulkhead structure for a ship superstructure and a manufacturing method thereof. Background Art

[0002] The ship superstructure mainly arranges various functional cabin areas above the main deck of the ship, such as cabins for the bridge, crew living quarters, entertainment rooms, medical cabins, air-conditioning machine rooms, switchboards, etc. There are many room partitions and complete functions. Due to requirements such as fire protection, fire prevention rating, and functional roles, a large number of steel bulkheads are used to separate the cabins.

[0003] The superstructure is arranged above the main deck of the ship. The control of the structural weight center of gravity has an important impact on the overall performance indicators of the ship. Usually, the thickness of the bulkhead plate and the size of the stiffeners are set to be as small as possible. At the same time, in order to ensure the effective space of the cabin, the height of the stiffeners needs to be controlled.

[0004] Due to the functional requirements of the cabin, in order to meet the layout requirements of outfitting professional equipment, cables, ventilation, pipe systems, doors and windows, etc., a large number of outfitting holes need to be opened on the cabin bulkhead, including door holes, window holes, cable holes, ventilation holes, pipe holes, etc.

[0005] Due to these objective factors, it is very difficult to control the flatness of the superstructure bulkhead after construction processes such as assembly and welding. In the conventional bulkhead plate and stiffener structure form, the bulkhead plate and the stiffeners need to be connected by welding. Due to deformation caused by welding heat input and other reasons, it is difficult to ensure the flatness of the bulkhead plate. In order to meet the flatness requirements, construction workers perform thermal straightening on the bulkhead plate and there is repair work such as inserting patch plates for local areas that cannot be corrected.

[0006] Compared with the conventional bulkhead plate and stiffener structure form, the corrugated bulkhead is formed by cold processing, which has the advantages of avoiding welding heat input deformation, reducing the original construction quantity, and structural lightweight. By setting corrugated joints, the stiffness of the corrugated bulkhead in the height direction is ensured. However, the layout of outfitting openings on the corrugated bulkhead has limitations. On the one hand, it is difficult to control the opening accuracy on the corrugation of the corrugated bulkhead. On the other hand, even if the opening is accurate, the outfitting penetrators cannot be effectively connected to the corrugated bulkhead. Moreover, the structure cannot be reinforced in the through direction of the corrugated opening. Summary of the Invention

[0042] The following refers to Figures 1 to 10To describe a combined bulkhead structure for a ship superstructure and its manufacturing method according to the present invention. In the description of this embodiment, the descriptions referring to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0043] As Figures 1 - 3 shown, an embodiment of the present invention provides a combined bulkhead structure for a ship superstructure, including a plurality of flat bulkheads 1 and corrugated bulkheads 2. A plurality of corrugated nodes 21 are evenly spaced on the corrugated bulkhead 2, and a plurality of outfitting openings 11 are formed on the flat bulkhead 1. Since the flat bulkhead 1 is a planar structure as a whole, setting the outfitting openings 11 on the flat bulkhead 1 facilitates the installation of penetrations. The plurality of flat bulkheads 1 and corrugated bulkheads 2 are spliced smoothly in a straight transition. Because the outfitting openings 11 correspond to the positions of the flat bulkheads 1, the positions of the flat bulkheads 1 can be determined according to the positions of the outfitting openings 11, and then the spacing relationship between the corrugated bulkheads 2 and the flat bulkheads 1 can be determined. That is, the corrugated bulkheads 2 are arranged at positions where the outfitting openings 11 do not need to be opened. The flat bulkheads 1 are arranged at positions where the outfitting openings 11 need to be opened. Stiffeners are provided on the flat bulkheads 1 at the boundaries of the outfitting openings 11, and the stiffeners are arranged along the boundary directions of the outfitting openings 11. Specifically, the stiffeners include vertical stiffeners 121 and horizontal stiffeners 122, which are arranged along the horizontal and vertical boundaries of the outfitting openings 11 respectively.

[0044] By combining the flat bulkheads 1 and the corrugated bulkheads 2, on the one hand, the corrugated nodes 21 on the corrugated bulkheads 2 can reduce the welding heat input deformation, reduce the original construction quantity, and achieve structural lightweight, ensuring the stiffness of the bulkhead structure in the height direction. On the other hand, by opening the outfitting openings 11 on the flat bulkheads 1, it is convenient to control the opening accuracy of the outfitting openings 11 and realize the effective connection between the penetrations and the bulkhead structure. At the same time, the stiffeners are provided to reinforce the bulkhead structure in the through direction of the outfitting openings 11.

[0045] Optionally, the corrugated nodes 21 are integrally in the shape of an arc groove. Through the arc transition, the whole corrugated nodes 21 are smoother, reducing stress concentration and improving the service life. Specifically, referring to Figure 4 , the corrugated nodes 21 include an inner surface arc R1, two inner surface arcs R2 symmetrically arranged along the axis of symmetry of the inner surface arc R1, an outer surface arc R3, and two outer surface arcs R4 symmetrically arranged along the axis of symmetry of the outer surface arc R3.

[0046] Furthermore, a plurality of through holes 31 are provided at intervals along the length direction of the upper and lower ends of the flat bulkhead 1 and the corrugated bulkhead 2. The through holes 31 on the corrugated bulkhead 2 are arranged at intervals from the corrugated nodes 21 to avoid damaging the corrugated nodes 21. A reinforcing plate 32 is fixedly provided on the wall plate at each through hole 31, and the reinforcing plate 32 is used to fixedly connect the flat wall plate and the corrugated bulkhead 2 to the upper deck plate 41 and the lower deck plate 42 of the ship superstructure respectively.

[0047] In order to strengthen the strength of the bulkhead structure in the direction of the through holes 31, when the flat bulkhead 1 and the corrugated bulkhead 2 are fixedly connected to the upper deck plate 41 and the lower deck plate 42 of the ship superstructure, angle steels 33 are vertically and fixedly inserted into the through holes 31. Optionally, the angle steels 33 are right angle steels 33, and the side walls of the angle steels 33 are attached to the side walls of the through holes 31.

[0048] Optionally, the reinforcing plate 32 is integrally in a hook-shaped structure. The vertical end of the reinforcing plate 32 is fixedly connected to the upper deck plate 41 or the lower deck plate 42. That is to say, when connected to the upper deck plate 41, the vertical end of the reinforcing plate 32 is fixedly connected to the upper deck plate 41. When connected to the lower deck plate 42, the vertical end of the reinforcing plate 32 is inverted and fixedly connected to the lower deck plate 42. The hook end of the reinforcing plate 32 is dragged and fixed on the lower surface of the angle steel 33 to further reinforce the strength.

[0049] In some embodiments of the present invention, both sides of the combined bulkhead structure are provided as flat bulkheads 1. A vertical panel 15 is provided at the vertical edge of the flat bulkhead 1, and T-bars 13 are fixedly provided at the top and bottom of the vertical panel 15. By providing the T-bars 13, it is convenient to connect the bulkhead structures to each other and ensure the connection strength. In addition, an end bracket 14 is further provided on the lower surface of the T-bar 13, and the end bracket 14 is also fixedly connected to the vertical panel 15. By providing the end bracket 14, the supporting strength of the T-bar 13 is enhanced.

[0050] As Figures 1 - 10 shown, the present invention also provides a manufacturing method for a combined bulkhead structure of a ship superstructure, which is used to manufacture the combined bulkhead structure in any of the above embodiments. The manufacturing method includes:

[0051] Step S1, cutting the wall plates of the combined bulkhead structure, including:

[0052] According to the drawing of the combined bulkhead structure, determine the positioning lines of the outfitting openings 11, the positioning lines of the through holes 31, the reference lines of the stiffeners, the center lines 61 of each corrugated node, and each turning point.

[0053] Taking the center lines 61 of each corrugated node as a reference, expand each corrugated node to both sides, and vertically mark the folding lines 62 of the corrugated nodes along the turning points on the development drawing;

[0054] According to the positioning lines of outfitting openings 11, the positioning lines of through holes 31, the reference lines of stiffeners, the center line 61 of the trough-shaped joint, and the press folding lines 62, mark the positions of outfitting openings 11, the positions of through holes 31, the reference lines of stiffeners, the center line 61 of the trough-shaped joint, and the press folding lines 62 on the panel of the modular bulkhead structure.

[0055] Among them, the reference lines of stiffeners include the horizontal reference line 52 of the stiffener and the vertical reference line 51 of the stiffener.

[0056] Optionally, use computer software to unfold and mark lines on the drawing of the modular bulkhead structure, which is more convenient to operate. At the same time, when using computer software to mark lines on the panel of the modular bulkhead structure, it can be directly exported, which is more automated.

[0057] Specifically, taking the trough-shaped joint 21 as a whole in the shape of an arc groove as an example, the turning point is the tangent point of the arc of the trough-shaped joint 21. Refer to Figure 2 , the turning points are the tangent points of arcs R1, R2, R3, and R4. Refer to Figure 5 , multiple press folding lines 62 are symmetric about the center line 61 of the trough-shaped joint.

[0058] Furthermore, refer to Figure 4 , when cutting the panel of the modular bulkhead structure, it also includes marking two horizontal reference lines 63 at intervals in the vertical direction on the panel of the modular bulkhead structure.

[0059] Step S2, process the cut panel of the modular bulkhead structure, including:

[0060] According to the marked positions of outfitting openings 11 and the positions of through holes 31, open outfitting openings 11 and through holes 31 on the panel of the modular bulkhead structure.

[0061] According to the marked reference lines of stiffeners, fix the stiffeners on the panel of the modular bulkhead structure.

[0062] According to the marked center line 61 of the trough-shaped joint and the press folding lines 62, perform pressing of the trough-shaped joint 21 on the panel of the modular bulkhead structure.

[0063] Furthermore, when performing pressing of the trough-shaped joint 21 on the panel of the modular bulkhead structure, a pressing die can be used.

[0064] The pressing die includes an upper die 71 and a lower die 72. The upper die 71 and the lower die 72 are respectively made by extending downward obliquely to both sides according to the inner surface and the outer surface of the trough-shaped joint 21. Die center lines 73 are marked on both the upper die 71 and the lower die 72 at positions corresponding to the center line 61 of the trough-shaped joint.

[0065] Specifically, taking the trough-shaped joint 21 as a whole in the shape of an arc groove as an example. Refer toFigures 4 - 6 , the arcs R5 and R6 in the pressing surface of the upper die 71 are respectively connected with smooth transitions referring to the arcs R1 and R2, and extend obliquely downward from both ends of the arc R6 to both sides. The arcs R7 and R8 in the pressing surface of the lower die 72 are respectively connected with smooth transitions referring to the arcs R3 and R4, and extend obliquely downward from both ends of the arc R8 to both sides. The die center line 73 of the upper die 71 is the central axis of the arc R5, and the die center line 73 of the lower die 72 is the central axis of the arc R7.

[0066] Since the wall panel of the modular bulkhead structure has a certain elasticity, by setting both ends of the pressing surfaces of the upper die 71 and the lower die 72 to be inclined downward, the pressing error caused by elasticity can be avoided during the pressing process, so that the pressing accuracy of the trough-shaped node 21 is higher.

[0067] Furthermore, the radius of the arc R5 of the upper die 71 is smaller than the arc R1 on the inner surface of the trough-shaped node 21. The radius of the arc R6 of the upper die 71 is larger than the arc R2 on the inner surface of the trough-shaped node 21. The radius of the arc R7 of the lower die 72 is equal to the arc R3 on the outer surface of the trough-shaped node 21. The radius of the arc R8 of the lower die 72 is smaller than the arc R4 on the outer surface of the trough-shaped node 21. Similarly, the pressing error caused by elasticity can also be avoided, so that the pressing accuracy of the trough-shaped node 21 is further improved.

[0068] Furthermore, using the pressing die to press the trough-shaped node 21 on the wall panel of the modular bulkhead structure includes:

[0069] Place the wall panel of the modular bulkhead structure on the lower die 72, align the center line marked on the wall panel of the modular bulkhead structure with the die center line 73 on the lower die 72, then align the die center line 73 of the upper die 71 with that of the lower die 72, and finally press down the upper die 71. By marking the die center line 73 and the center line 61 of the trough-shaped node, it is convenient to position during the pressing operation of the trough-shaped node 21, and the operation is relatively simple.

[0070] Furthermore, after processing the cut wall panel of the modular bulkhead structure, vertical panels, T-bars and end brackets can be fixed at the edge of the flat bulkhead 1.

[0071] Step S3, inspect the formed modular bulkhead structure, including checking the accuracy of the trough-shaped node 21, checking the accuracy between adjacent trough-shaped nodes 21, and checking the accuracy of the transition area of the modular bulkhead structure.

[0072] Furthermore, the accuracy check of the trough-shaped node 21 is carried out using the first inspection tooling 81. Refer to Figure 7, the first inspection tooling 81 is made according to the inner surface of the grooved node 21 and extends horizontally to both sides. The first inspection tooling 81 is marked with a first reference line 811 and a second reference line 812. The first reference line 811 is located at the position corresponding to the center line 61 of the first inspection tooling 81 and the grooved node, and the second reference line 812 is at the position corresponding to the pressing fold line 62 of the first inspection tooling 81 and the grooved node.

[0073] The accuracy verification of the grooved node 21 is carried out by using the first inspection tooling 81, including placing the first inspection tooling 81 inside the grooved node 21 formed by pressing. And making the first reference line 811 correspond to the center line 61 of the grooved node, and checking whether each second reference line 812 corresponds to each pressing fold line 62 of the grooved node and whether the first inspection tooling 81 fits the inner surface of the grooved node 21. When the first inspection tooling 81 fits the inner surface of the grooved node 21 and each second reference line 812 corresponds to each pressing fold line 62 of the grooved node, it indicates that the accuracy of the grooved node 21 meets the requirements.

[0074] By making the first inspection tooling 81 and pre-marking the pressing fold line 62 on the wall panel of the modular bulkhead structure, when the accuracy verification of the grooved node 21 is carried out, using the pressing fold line 62 as the verification reference makes the verification operation simpler and the verification result obvious at a glance.

[0075] Furthermore, the accuracy verification between adjacent grooved nodes 21 is carried out by using the second inspection tooling 82. Refer to Figure 8 , the second inspection tooling 82 is made by splicing according to the inner surface of adjacent grooved nodes 21 and extending horizontally to both sides. The second inspection tooling 82 is marked with a third reference line 821 and a fourth reference line 822. The third reference line 821 is located at the position corresponding to the center line 61 of the second inspection tooling 82 and the grooved node. The fourth reference line 822 is located at the position corresponding to the pressing fold line 62 of the second inspection tooling 82 and the grooved node.

[0076] The accuracy verification between adjacent grooved nodes 21 is carried out by using the second inspection tooling 82, including placing the second inspection tooling 82 along two horizontal reference lines 63 successively and making one of the third reference lines 821 correspond to the center line 61 of one of the grooved nodes. Checking whether the remaining third reference lines 821 correspond to the center lines 61 of the remaining grooved nodes, whether the fourth reference lines 822 correspond to the pressing fold lines 62 of the grooved nodes, and whether the second inspection tooling 82 fits the inner surfaces of each grooved node 21. When the second inspection tooling 82 fits the inner surfaces of each grooved node 21, and the remaining third reference lines 821 also correspond to the center lines 61 of the remaining grooved nodes and the fourth reference lines 822 also correspond to the pressing fold lines 62 of the grooved nodes, it indicates that the accuracy between adjacent grooved nodes 21 meets the requirements.

[0077] By manufacturing the second inspection tooling 82 and pre - marking the horizontal reference line 63 in advance, it is possible to avoid the second inspection tooling 82 being placed obliquely, which affects the calibration result. Two horizontal reference lines 63 are set, and calibration is carried out from different positions to make the calibration result more accurate. At the same time, taking the center line 61 and the pressing fold line 62 of the trough - shaped node as the calibration reference makes the calibration operation simpler and the calibration result obvious at a glance.

[0078] Furthermore, the accuracy calibration of the transition area of the combined bulkhead structure is carried out by using the third inspection tooling 83. Refer to Figure 9 , the third inspection tooling 83 is fabricated by following the inner surface of the trough - shaped node 21 of the trough - shaped bulkhead 2 and horizontally extending to both sides to the adjacent flat bulkhead 1 for splicing. The fifth reference line 831, the sixth reference line 832 and the seventh reference line 833 are marked on the third inspection tooling 83. The fifth reference line 831 is located at the position corresponding to the center line 61 of the trough - shaped node on the third inspection tooling 83. The sixth reference line 832 is located at the position corresponding to the pressing fold line 62 of the trough - shaped node on the third inspection tooling 83. The seventh reference line 833 is located at the position of the vertical stiffener reference line 51 corresponding to the flat bulkhead 1.

[0079] Using the third inspection tooling 83 to carry out the accuracy calibration of the transition area of the combined bulkhead structure includes placing the third inspection tooling 83 along the two horizontal reference lines 63 successively and making the fifth reference line 831 correspond to the center line 61 of the trough - shaped node. Check whether the sixth reference line 832 corresponds to the pressing fold line 62 of the trough - shaped node, whether the seventh reference line 833 corresponds to the vertical stiffener reference line 51, and whether the third inspection tooling 83 fits the inner surface of the trough - shaped node 21. When the third inspection tooling 83 fits the inner surface of the trough - shaped node 21, and the sixth reference line 832 corresponds to the pressing fold line 62 of the trough - shaped node and the seventh reference line 833 corresponds to the vertical stiffener reference line 51, it indicates that the accuracy of the transition area of the combined bulkhead structure meets the requirements.

[0080] By manufacturing the third inspection tooling 83 and pre - marking the horizontal reference line 63 in advance, it is possible to avoid the third inspection tooling 83 being placed obliquely, which affects the calibration result. Two horizontal reference lines 63 are set, and calibration is carried out from different positions to make the calibration result more accurate. Combining the pre - marked vertical stiffener reference line 51, the center line 61 and the pressing fold line 62 of the trough - shaped node makes the calibration operation simpler and the calibration result obvious at a glance.
