Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, specifically relating to a method for controlling the construction precision of container ship superstructure sections. Background Technology

[0002] Due to the thin plates, limited internal structure, and large section widths, the superstructure of container ships presents significant challenges in precision control during construction. The main problems include: (1) The deck and longitudinal walls of the superstructure are large, spliced ​​components, making it difficult to control the overall dimensions of these components; (2) The superstructure's bulkheads and deck have numerous ribs, and after splicing and installation, misalignment can easily occur between the bulkhead ribs and the ribs on the deck; (3) During loading, unloading, and transportation, the superstructure sections are placed upside down with the deck as the base surface, with the sides extending outwards. (3) The platform sags and tilts upwards after the section is erected and assembled, causing water to accumulate on the deck surface to be unable to drain smoothly; (4) Due to the thinness of the plate, the superstructure section has a large amount of welding during the section manufacturing process, which is prone to deformation and shrinkage. Large deformation can lead to a large amount of heat treatment, resulting in a large amount of shrinkage, making it difficult to control the overall size data of the section; (5) The superstructure section is relatively wide and has few internal structures, resulting in poor rigidity of the section. Deformation will occur during transportation and hoisting, causing the section to fail to meet the accuracy requirements of the installation. Summary of the Invention

[0003] The purpose of this invention is to provide a method for controlling the construction accuracy of superstructure sections on container ships, which solves the problem of poor superstructure section accuracy caused by thin plates, fewer internal structures, and larger section widths, ensuring that the superstructure sections meet the requirements for mounting accuracy and use, and reducing scrap and rework during the section construction process.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A method for controlling the construction precision of container ship overbuilding sections includes panel components, wherein the panel components are decks, longitudinal bulkheads, and transverse bulkheads, and the decks, longitudinal bulkheads, and transverse bulkheads are all assembled and welded from multiple panels, comprising the following steps:

[0006] Step S1: Precision control of panel splicing and welding of the components;

[0007] Step S1.1: Determine the length of the panel to be added in the length and width directions of the ship;

[0008] Step S1.2: Select one of the panel pieces as the reference panel piece, assemble the panels of the reference panel piece on a flat ground, and determine the longest horizontal edge line and the longest vertical edge line on the reference panel piece. Then, assemble the panels of other panel pieces along the longest horizontal edge line and the longest vertical edge line respectively.

[0009] Step S1.3: Measure the dimensions of the corresponding panels for each assembly. If the dimensions meet the accuracy requirements, weld the panels together to form the deck, the longitudinal wall panel, and the transverse wall panel. If the dimensions are too small, adjust the spacing between the panels before welding. If the dimensions are too large, mark the edges and trim before welding.

[0014] Step S3: Segmented assembly and its precision control;

[0015] Step S3.1: Using the deck as a frame, reverse deformation is performed on the extended deck in the height direction. The extended deck is the part of the deck that extends out of the outermost longitudinal wall plate.

[0016] Step S3.2: Install the longitudinal bulkhead on the deck according to the extension direction of the longitudinal reference line of the longitudinal bulkhead, and align the longitudinal reference line of the longitudinal bulkhead with the longitudinal reference line of the deck; install the transverse bulkhead on the deck according to the extension direction of the transverse reference line of the transverse bulkhead, and align the transverse reference line of the transverse bulkhead with the transverse reference line of the deck.

[0017] Step S3.3: The deck is welded to the transverse wall plate and the longitudinal wall plate respectively to form an assembly structure;

[0018] As a preferred embodiment of the present invention, step S4 is further included: transporting and hoisting the assembly structure, wherein reinforcing materials are welded onto the assembly structure.

[0019] As a preferred embodiment of the present invention, in step S4, when the deck is welded to the longitudinal wall plate and the transverse wall plate to form a wall structure, the reinforcing material is welded to the lower part of the skeleton of the longitudinal wall plate and the lower part of the skeleton of the transverse wall plate, and the reinforcing material is arranged perpendicular to the skeleton.

[0020] As a preferred embodiment of the present invention, in step S4, when the longitudinal wall plate or the transverse wall plate has an opening, the reinforcing material is welded to the skeleton at the opening, and the reinforcing material is a triangular structure composed of two diagonal braces and a crossbeam.

[0021] As a preferred embodiment of the present invention, in step S4, the reinforcing material is welded between the protruding deck and the strong structural point, and the strong structural point, the reinforcing material, and the protruding deck together form a triangular structure.

[0022] As a preferred embodiment of the present invention, the reinforcing material is channel steel or flat steel.

[0023] As a preferred embodiment of the present invention, in step S1.1, the length value is the sum of the shrinkage of the longitudinal rib or longitudinal girder relative to the main board and the shrinkage of the fire adjustment.

[0024] As a preferred embodiment of the present invention, in step S1.1, the shrinkage amount of the longitudinal rib or longitudinal girder relative to the main board is 0.1 mm / step, the shrinkage amount of the heat treatment is 0.4 mm / step, and the length value is 0.5 mm / step.

[0025] As a preferred embodiment of the present invention, in step S1.2, the reference panel is a deck, the panels of the transverse wall panel are spliced ​​along the longest longitudinal edge of the deck, and the panels of the longitudinal wall panel are spliced ​​along the longest transverse edge of the deck.

[0026] As a preferred embodiment of the present invention, in step S1.3, the data dimensions include the size of the plate, the diagonal length, the extension value data, and the allowance to be added.

[0027] As a preferred embodiment of the present invention, in step S2.1, the deck transverse reference line is arranged perpendicularly to the deck longitudinal reference line, the deck transverse reference line is located at the middle position of the deck in the transverse extension direction, the deck longitudinal reference line is located at the middle position of the deck in the longitudinal extension direction; the longitudinal reference line of the longitudinal bulkhead is located at the middle position of the longitudinal bulkhead; the transverse reference line of the transverse bulkhead is located at the middle position of the transverse bulkhead.

[0028] As a preferred embodiment of the present invention, in step S2.1, the deck transverse reference line, the deck longitudinal reference line, the longitudinal reference line of the longitudinal wall plate, and the transverse reference line of the transverse wall plate are all drawn by laser.

[0029] As a preferred embodiment of the present invention, in step S3.1, the portion of the deck extending beyond the longest longitudinal edge line is subjected to a reverse deformation of 5mm / stage in the height direction.

[0030] The construction precision control method for container ship superstructure sections provided by this invention has the following advantages compared with the prior art:

[0031] (1) By measuring and correcting the data dimensions of the plates and the welding spacing between the plates, the present invention can effectively control the main dimensions (such as squareness) of the spliced ​​plate after the plates are spliced ​​and welded to form a spliced ​​plate; at the same time, by adding the extension value of the spliced ​​plate in the length and width directions of the ship, the shrinkage of welding and heat treatment during the segmented construction process can be offset, thereby ensuring the overall accuracy after segmented construction.

[0032] (2) The present invention marks the rib installation line on the splicing parts with the baseline as the reference and adds the extension length value on both sides according to each increment. Ribs are installed and welded on the rib installation line, which can offset the shrinkage of the ribs during welding and heat treatment, and ensure the accuracy of the rib installation.

[0033] (3) In this invention, the longitudinal bulkheads are installed on the deck along the extension direction of their longitudinal reference lines, and the longitudinal reference lines of the bulkheads are aligned with the longitudinal reference lines of the deck; the transverse bulkheads are installed on the deck along the extension direction of their transverse reference lines, and the transverse reference lines of the transverse bulkheads are aligned with the transverse reference lines of the deck. This operation ensures that the ribs in the longitudinal bulkheads and the ribs in the transverse bulkheads are aligned with the ribs in the deck, avoiding misalignment;

[0034] (4) By adding anti-deformation to the extended deck in the height direction, the present invention can offset the sag of the extended deck, avoid the phenomenon of the extended deck tilting upward after the segmented upright assembly, and ensure that the water accumulated at the extended deck can be discharged smoothly.

[0035] It is evident that by formulating relevant control measures, the problem of poor superstructure section accuracy caused by thin plates, fewer internal structures, and larger section widths in container ships can be solved, thereby ensuring that the superstructure sections meet the requirements for mounting accuracy and use, and reducing scrap and rework during the section construction process.

[0044] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0045] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, 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 invention. It should be understood that the terms "first," "second," etc., are used in this invention to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0046] like Figures 1 to 5 As shown, a preferred embodiment of the present invention provides a method for controlling the construction accuracy of a container ship superstructure section, which includes panel components, wherein the panel components are deck 1, longitudinal bulkhead 2, and transverse bulkhead 3, and the deck 1, the longitudinal bulkhead 2, and the transverse bulkhead 3 are all spliced ​​and welded from multiple panels, and includes the following steps:

[0047] Step S1: Precision control of panel splicing and welding of the components.

[0048] Step S1.1: Determine the length of the panel to be added in the length and width directions of the ship.

[0049] It should be noted that the length measurement is the sum of the shrinkage of the longitudinal ribs or girder relative to the mainboard and the shrinkage of the fire treatment. In this embodiment, the shrinkage of the longitudinal ribs or girder relative to the mainboard is 0.1 mm / step, and the shrinkage of the fire treatment is 0.4 mm / step, that is, the length measurement is 0.5 mm / step, and no additional length measurement is required in the height direction.

[0050] Step S1.2: Select one of the panel pieces as the reference panel piece, assemble the panels of the reference panel piece on a flat ground, and determine the longest horizontal edge line and the longest vertical edge line on the reference panel piece. Then, assemble the panels of other panel pieces along the longest horizontal edge line and the longest vertical edge line respectively.

[0051] In this embodiment, the reference panel is preferably a deck 1, the panels of the transverse wall panel 3 are spliced ​​on the longest longitudinal edge line 12 of the deck 1, and the panels of the longitudinal wall panel 2 are spliced ​​on the longest transverse edge line 11 of the deck 1.

[0052] Step S1.3: Measure the dimensions of the corresponding panels for each assembly. If the dimensions meet the accuracy requirements, weld the panels together to form the deck 1, the longitudinal wall panel 2, and the transverse wall panel 3. If the dimensions are too small, adjust the spacing between the panels before welding. If the dimensions are too large, mark the edges and trim before welding.

[0053] It should be noted that the data dimensions include the size of the plate, the diagonal length, the extension value, and the allowance to be added. By measuring and correcting the data dimensions of the plate and the welding spacing between the plates, the main dimensions (such as squareness) of the spliced ​​plate can be well controlled after the plates are spliced ​​and welded to form a spliced ​​plate. At the same time, by adding extension values ​​to the spliced ​​plates in the length and width directions of the ship, the shrinkage caused by welding and heat treatment during the segmented construction process can be offset, thereby ensuring the overall accuracy after segmented construction.

[0054] Step S2: Precision control of the installation of the framing components.

[0055] Step S2.1: Determine and mark the deck transverse reference line 13, deck longitudinal reference line 14, longitudinal bulkhead longitudinal reference line 21, and transverse bulkhead transverse reference line 31 respectively. In this embodiment, the deck transverse reference line 13, the deck longitudinal reference line 14, the longitudinal bulkhead longitudinal reference line 21, and the transverse bulkhead transverse reference line 31 are preferably drawn by laser.

[0056] Step S2.2: On the deck 1, using the deck transverse reference line 13 as a reference, mark the first aggregate installation line on both sides, adding the extension value in step S1.1 to each increment; on the deck 1, using the deck longitudinal reference line 14 as a reference, mark the second aggregate installation line on both sides, adding the extension value in step S1.1 to each increment; on the longitudinal bulkhead 2, using the longitudinal reference line 21 of the longitudinal bulkhead 21 as a reference, mark the third aggregate installation line on both sides, adding the extension value in step S1.1 to each increment; on the transverse bulkhead 3, using the transverse reference line 31 of the transverse bulkhead 31 as a reference, mark the fourth aggregate installation line on both sides, adding the extension value in step S1.1 to each increment.

[0057] Step S2.3: Install and weld the ribs 4 on the first rib installation line, the second rib installation line, the third rib installation line and the fourth rib installation line respectively, so as to offset the shrinkage of the ribs 4 during welding and heat treatment, and ensure the installation accuracy of the ribs 4.

[0058] Step S3: Segmented assembly and its precision control.

[0059] Step S3.1: As Figure 2As shown, the deck is used as the frame surface for reverse construction, and the extended deck 5 is subjected to reverse deformation in the height direction. The extended deck 5 is the part of the deck 1 that extends out of the outermost longitudinal wall plate 2.

[0060] It should be noted that, in this embodiment, the portion of the deck 1 extending beyond the longest longitudinal edge 12 is preferably subjected to a 5mm / stage anti-deformation in the height direction. Since the superstructure sections are placed upside down with the deck 1 as the base during loading, parking, and transportation, sagging will occur at the two sides of the deck 1 extending to the platform. By adding anti-deformation to the extended deck 5 in the height direction, the sagging of the extended deck 5 can be offset, preventing the extended deck 5 from tilting upwards after the sections are upright and assembled, and ensuring that water accumulated at the extended deck 5 can be drained smoothly.

[0061] Step S3.2: Install the longitudinal bulkhead 2 onto the deck 1 along the extension direction of the longitudinal reference line 21, aligning the longitudinal reference line 21 with the longitudinal reference line 14 of the deck; install the transverse bulkhead 3 onto the deck 1 along the extension direction of the transverse reference line 31, aligning the transverse reference line 31 with the transverse reference line 13 of the deck. This operation ensures that the stiffeners 4 in the longitudinal bulkhead 2 and the stiffeners 4 in the transverse bulkhead 3 are aligned with the stiffeners 4 in the deck 1, preventing misalignment.

[0062] Step S3.3: The deck 1 is welded to the transverse wall plate 3 and the longitudinal wall plate 2 to form an assembly structure.

[0063] Step S4: Transport and hoist the assembled structure.

[0064] It is evident that after steps S1, S2, and S3, the problem of poor superstructure segment accuracy caused by thin plates, fewer internal structures, and larger segment widths in container ship superstructures can be solved, thereby ensuring that the superstructure segments meet the requirements for mounting accuracy and use, and reducing scrap and rework during the segment construction process.

[0065] Furthermore, to improve the rigidity of the segments and prevent deformation during transportation and hoisting, which could cause the segments to fail to meet the accuracy requirements of the assembly, in step S4, reinforcing materials are welded onto the assembly structure. In this embodiment, the reinforcing material 6 is preferably channel steel or flat steel, and has the following three forms:

[0066] (I) As Figure 3As shown, when the deck 1 is welded to the longitudinal wall plate 2 and the transverse wall plate 3 to form a wall structure, the reinforcing member 6 is welded to the rib 4 on the longitudinal wall plate 2 near the lower opening 41 and to the rib 4 on the transverse wall plate 3 near the lower opening 41. The reinforcing member 6 is arranged perpendicularly to the rib 4. It should be noted that the lower opening 41 of the rib 4 is the end of the rib 4 away from the deck 1; the upper opening 42 of the rib 4 is the end of the rib 4 near the deck 1.

[0067] (II) As Figure 4 As shown, when the longitudinal wall plate 2 or the transverse wall plate 3 is provided with an opening 8, the reinforcing member 6 is welded to the skeleton 4 at the opening 8. The reinforcing member 6 is a triangular structure composed of two diagonal braces 61 and a crossbeam 62.

[0068] (III) As Figure 5 As shown, the reinforcing member 6 is welded between the protruding deck 5 and the strong structural point 7, and the strong structural point 7, the reinforcing member 6, and the protruding deck 5 together form a triangular structure. It should be noted that the structural connection point can withstand relatively stronger forces in the direction of force application compared to other structural elements, such as... Figure 1 As shown, the load-bearing capacity of point A (the connection point between longitudinal wall panel 2 and transverse wall panel 3) is stronger than that of point B, that is, point A is the strong structural point 7.

[0069] For example, in step S2.1, the deck transverse reference line 13 is arranged perpendicularly to the deck longitudinal reference line 14. The deck transverse reference line 13 is located at the midpoint of the deck 1 in the transverse extension direction, and the deck longitudinal reference line 14 is located at the midpoint of the deck 1 in the longitudinal extension direction. The longitudinal reference line 21 of the bulkhead is located at the midpoint of the bulkhead 2, and the transverse reference line 31 of the transverse bulkhead is located at the midpoint of the transverse bulkhead 3. This design can better reduce the error during the installation of the ribs 4, thereby further ensuring that the ribs 4 in the longitudinal bulkhead 2 and the ribs 4 in the transverse bulkhead 3 can be aligned with the ribs 4 in the deck 1, avoiding misalignment.

[0070] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0071] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
