Description

Technical Field

[0001] This application relates to the technical field of ships, and particularly to a marine support beam structure and a ship. Background Art

[0002] The development trend of support beam technology is moving forward in multiple key directions. On the one hand, with the progress of materials science, high-strength and lightweight materials are increasingly widely used in the manufacture of support beams. Lightweight alloys such as aluminum alloys are gradually emerging. They can not only effectively reduce the hull weight, improve the fuel economy and speed of the ship, but also optimize the overall performance of the ship to a certain extent. On the other hand, at the design level, with the help of advanced digital simulation technologies such as finite element analysis software, engineers can more accurately simulate the stress conditions of the support beam under various working conditions, and then optimize the design of its structure, which greatly improves the design efficiency and accuracy. In addition, the modular design concept has also begun to be incorporated into the design and manufacturing process of support beams. By splitting the support beam into standardized modules, it is convenient for production, installation and later maintenance, significantly improving the overall efficiency of shipbuilding.

[0003] However, there are still some prominent problems in the current ship support beam technology. During the actual design process, after the specifications of the support beam are calculated according to the specifications, it is very difficult to combine with the outfitting layout. For example, at the ends of stepped and tapered beams, in order to eliminate structural hard points and ensure the continuity of force, end structures such as brackets, fillets, and additional stiffeners on the back are often used. However, these measures often require a lot of space, seriously conflicting with the space requirements of the outfitting layout. Moreover, to meet the requirements of end alignment, during the layout concept, the calculated specifications of the support beam often need to be selected according to the highest strength requirements, which inevitably leads to design redundancy, a significant increase in steel costs, and also makes it difficult to achieve refined design of the support beam specifications.

[0023] Figure 1 It is a three-dimensional structure schematic diagram of the marine support beam structure of the embodiment of this application. Figure 2 It is a front view structure schematic diagram in the x direction in the figure. Please refer to Figure 1 、 Figure 2 As shown, this embodiment provides a marine support beam structure, including: a tapered beam web 100, a tapered beam panel 200, a main beam web 300, a main beam panel 400, a secondary beam web 500, a secondary beam panel 600, and a secondary beam panel stiffener 700.

[0024] The bottom of the tapered beam web 100 extends downward in a stepped shape; the top of the tapered beam web 100 abuts vertically against the first mother board 1200; the tapered beam panel 200 is connected to the bottom of the tapered beam web 100; the main beam web 300 is vertically connected to the tapered beam web 100, and the widest part of the tapered beam web 100 is flush with the main beam web 300; the bottom of the main beam web 300 is aligned and connected to the second mother board 1300; the top of the main beam web 300 is aligned and connected to the third mother board 1400, and the third mother board 1400 is perpendicular to the first mother board 1200; the main beam panel 400 is connected to the bottom of the main beam web 300; the secondary beam web 500 is vertically connected to the side of the main beam web 300 opposite to the tapered beam web 100, and the top surface of the secondary beam web 500 is flush with the top surface of the main beam web 300; the secondary beam panel 600 is connected to the bottom of the secondary beam web 500; the secondary beam panel stiffener 700 is connected between the secondary beam panel 600 and the main beam web 300.

[0025] The marine support beam structure provided in this embodiment breaks through the structural form limitation of the end connection of the existing marine support beam, saves the structural space occupied by the end treatment of the tapered beam, reduces the interference of outfitting layout, reduces the steel design and usage costs, and can finely design the support beam specifications according to actual needs, and is applicable to the treatment and application of the end conflicts of different marine support beam structures.

[0026] The first mother board 1200 is arranged in the X-Y plane shown in the figure. The second mother board 1300, the third mother board 1400 and the main beam web 300 are arranged in the same plane. Specifically, they are arranged in the X-Z plane shown in the figure. The tapered beam web 100 and the secondary beam web 500 are arranged in the same plane. Specifically, they are arranged in the Y-Z plane shown in the figure.

[0027] The widest part of the tapered beam web 100 is flush with the main beam web 300 to eliminate the structural hard points of the tapered beam. A detailed description is given with reference to the drawings. Generally, the widest part of the tapered beam web 100 is the position where the tapered beam web 100 is connected to the main beam web 300. It can also be seen from the drawings here that from the end of the tapered beam web 100 away from the main beam web 300 to the end of the tapered beam web 100 close to the main beam web 300, the bottom of the tapered beam web 100 extends downward in a stepped manner, so that the height of the tapered beam web 100 in the Z-axis direction gradually increases. At the position where the tapered beam web 100 is connected to the main beam web 300, it is the maximum height of the tapered beam web 100 in the Z-axis direction, which can also be said to be the widest part of the tapered beam web 100. Then the height distance of the widest part of the tapered beam web 100 in the Z-axis direction is equal to the height distance of the main beam web 300 in the Z-axis direction, that is, the widest part of the tapered beam web 100 is flush with the main beam web 300. It should be noted here that the thickness of the tapered beam web 100 in the X-axis direction also needs to be equal to the thickness of the main beam web 300 in the X-axis direction.

[0028] Here, regarding the tapered beam panel 200, it also needs to be explained that from the end of the tapered beam panel 200 away from the main beam web 300 to the end of the tapered beam panel 200 close to the main beam web 300, it successively includes: a first plate segment 201, a second plate segment 202, and a third plate segment 203; both ends of the second plate segment 202 are aligned and connected to the ends of the first plate segment 201 and the third plate segment 203 away from the main beam web 300 respectively; the end of the third plate segment 203 close to the main beam web 300 is aligned and connected to the main beam panel 400.

[0029] A detailed description is given with reference to the drawings. The widths of the first plate segment 201, the second plate segment 202, and the third plate segment 203 in the X-axis direction and the heights in the Z-axis direction are all the same to achieve the aligned connection between the first plate segment 201, the second plate segment 202, and the third plate segment 203. The first plate segment 201 and the second plate segment 202 are arranged at an angle, and the second plate segment 202 and the third plate segment 203 are arranged at an angle, which are correspondingly set to match the stepped downward extension of the bottom of the tapered beam web 100. It should be noted here that the height of the end of the third plate segment 203 close to the main beam web 300 in the Z-axis direction is the same as the height of the main beam panel 400 in the Z-axis direction to achieve the aligned connection between the end of the third plate segment 203 close to the main beam web 300 and the main beam panel 400 to eliminate the structural hard points of the tapered beam.

[0030] In this embodiment, between the tapered beam panel and the tapered beam web 100, between the main beam panel 400 and the main beam web 300, and between the minor beam panel and the minor beam web, a vertically arranged structure is adopted.

[0031] In an alternative embodiment, between the tapered beam panel and the tapered beam web 100, between the main beam panel 400 and the main beam web 300, and between the minor beam panel and the minor beam web, a certain inclination angle can also be set.

[0032] In this embodiment, the minor beam panel stiffener 700 is aligned and connected to the minor beam panel 600. A detailed description is given with reference to the drawings. The minor beam panel 600, the minor beam panel stiffener 700, and the main beam panel 400 are all arranged in the X-Y plane shown in the figure, and in the Z-axis direction, the minor beam panel stiffener 700 is located above the main beam panel 400. The minor beam panel 600 is installed on the main beam web through the minor beam panel stiffener 700. Here, the minor beam panel stiffener 700 is connected to the part of the minor beam web extending outside the minor beam panel 600. It should be noted here that the height of the minor beam panel stiffener 700 in the Z-axis direction is equal to the height of the minor beam panel 600 in the Z-axis direction to ensure that the minor beam panel stiffener 700 is aligned and connected to the minor beam panel 600 and eliminate the hard points of the minor beam structure.

[0033] It should be noted here that this embodiment is not limited to the application in tapered beams. For the beam structure that can serve as a support beam corresponding to the tapered beam, the arrangement methods of its ends with the main beam and the minor beam can all refer to the methods adopted in this embodiment.

[0034] In an embodiment of the present application, it further includes: a first angle steel stiffener 800. A brief introduction to the first angle steel stiffener 800 is as follows. The first angle steel stiffener 800 includes a first wing plate and a second wing plate, and the first wing plate and the second wing plate are connected at an angle perpendicular to each other. Here, the position where the first end of the first wing plate is connected to the second wing plate is the bending angle of the first angle steel stiffener 800.

[0035] Specifically, the first end of the first wing plate abuts against the end of the main beam panel 400 away from the tapered beam panel 200. The second end of the first wing plate abuts against the side of the second mother plate 1300 opposite to the tapered beam web 100.

[0036] In this embodiment, the first angle steel stiffener 800 is vertically arranged in the Z-axis direction. Specifically, the upper end of the first angle steel stiffener 800 vertically abuts against the lower side of the main beam panel 400. The setting of the first angle steel stiffener 800 enhances the structural strength of the second mother plate 1300 and the main beam panel 400.

[0037] In an embodiment of the present application, it further includes: a first angle steel reinforcing rib 800 and a second angle steel reinforcing rib 900. For the structure of the second angle steel reinforcing rib 900, reference can be made to the structure of the first angle steel reinforcing rib 800, and details will not be elaborated here. The second angle steel reinforcing rib 900 is vertically installed on the side of the girder web 300 opposite to the tapered beam web 100, and vertically abuts between the upper part of the girder panel 400 and the lower part of the small beam panel reinforcing rib 700. The setting of the second angle steel reinforcing rib 900 enhances the structural strength of the girder.

[0038] Furthermore, the arrangement position of the second angle steel reinforcing rib 900 needs to ensure alignment with the first angle steel reinforcing rib 800 in the Z-axis direction to form a vertically aligned reinforcement structure. It should be noted that the first angle steel reinforcing rib 800 and the second angle steel reinforcing rib 900 generally select the same specification to ensure that the ends are aligned and structural hard points are eliminated.

[0039] In an embodiment of the present application, it further includes: a first angle steel reinforcing rib 800, a second angle steel reinforcing rib 900, and an angle steel panel reinforcing rib 1000.

[0040] The angle steel panel reinforcing rib 1000 is vertically installed on the side of the girder web 300 opposite to the tapered beam web 100, and vertically abuts above the small beam panel reinforcing rib 700. It should be noted here that the angle steel panel reinforcing rib 1000 is installed on the small beam web. The setting of the angle steel panel reinforcing rib 1000 enhances the structural strength between the small beam and the girder.

[0041] Furthermore, the arrangement position of the angle steel panel reinforcing rib 1000 needs to ensure alignment with the first angle steel reinforcing rib 800 and the second angle steel reinforcing rib 900 in the Z-axis direction to form a vertically aligned reinforcement structure.

[0042] In an embodiment of the present application, it further includes: a first angle steel reinforcing rib 800, a second angle steel reinforcing rib 900, an angle steel panel reinforcing rib 1000, and a third angle steel reinforcing rib 1100.

[0043] The third angle steel reinforcing rib 1100 is vertically installed on the side of the third mother board 1400 opposite to the tapered beam web 100, and the lower end of the third angle steel reinforcing rib 1100 vertically abuts against the first mother board 1200. The setting of the third angle steel reinforcing rib 1100 enhances the structural strength of the small beam and the third mother board 1400.

[0044] For the structure of the third angle steel reinforcing rib 1100, reference can be made to the structures of the second angle steel reinforcing rib 900 and the first angle steel reinforcing rib 800, and details will not be elaborated here.

[0045] Furthermore, the arrangement position of the third angle steel stiffener 1100 needs to ensure alignment with the first angle steel stiffener 800, the second angle steel stiffener 900, and the angle steel panel stiffener 1000 in the Z-axis direction to form a vertical alignment strengthening structure. It should be noted that the first angle steel stiffener 800, the second angle steel stiffener 900, and the third angle steel stiffener 1100 generally select the same specification to ensure that the ends are aligned and structural hard points are eliminated.

Here, the first mother board can be used as the deck, the second mother board as the longitudinal wall, and the third mother board as the transverse wall for arrangement.
