Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to a ship section assembly structure. Background Technology

[0002] The assembly and installation of modular panels in ship sectional construction is a highly precise and systematic process involving key aspects such as jig preparation, hoisting and positioning, welding control, precision testing, and quality acceptance. The installation process is illustrated in application publication number CN 113697655 A, which proposes an assembly method for ship hull decks. This assembly includes multiple panels, at least one of which has multiple hoisting holes penetrating the panel. The panel forming the hoisting holes includes a first region and a second region spaced apart. A portion of the hoisting holes is located in the first region, and another portion is located in the second region. The first region includes a first point, and the second region includes a second point. The portion of the straight line segment defined by the first and second points, intercepted by the panel, is the longest among all straight lines passing through the panel that are intercepted by the panel.

[0003] Structurally, the current segmented assembly can result in large gaps at the joints due to various factors, such as localized upward arching caused by the shrinkage of sheet metal during welding, insufficient support surface of the jig, inadequate local support precision of the jig, and deformation of the plates during forklift handling and hoisting.

[0004] This feedback leads to problems such as large gaps in certain areas and high assembly difficulty during the final installation. Utility Model Content

[0005] Therefore, this utility model provides a ship section assembly structure that solves the problem of insufficient precision after current section assembly.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A segmented ship assembly structure includes a frame, a base plate at the bottom of the frame, and an outer plate covering the outer surface of the frame. The long end of the frame is defined as longitudinal, and the short end as transverse. The frame is composed of transverse and longitudinal plates arranged alternately on the base plate. Several mounting slots are evenly distributed at the upper and lower ends of the longitudinal plates. The surfaces of the base plate and the outer plate are provided with insertion plates that can be inserted into the mounting slots. The insertion plates are in the shape of a "J" shape with a long base and a bent portion at the end of the long base. The mounting slots are in the shape of a "J" shape with a long base groove and a bent groove at the end of the long base groove.

[0008] When the base plate, outer plate and frame are installed, the long strip base of each of the plug-in plates is inserted into the corresponding long strip base groove, the bent part and the bending groove are arranged on both sides of the long strip base and are opposite to each other, and each of the longitudinal plates is provided with a connecting plate for fixing the base plate and the outer plate.

[0009] Preferably, a reinforcing member is arranged between two adjacent longitudinal plates, the reinforcing member including longitudinal sub-plates extending along the longitudinal direction and connecting sub-plates connecting the longitudinal sub-plates and each transverse plate.

[0010] Preferably, the reinforcing member further includes a triangular bent plate disposed between the plug plate and the base plate or the outer plate.

[0011] Preferably, the open end of the elongated base groove is provided with a relief opening.

[0012] Preferably, each of the plug-in plates is provided with a plurality of connecting plates distributed longitudinally, and each of the connecting plates is provided with a connecting groove adapted to the shape of the plug-in plate. When the base plate, the outer plate and the frame are installed, each of the connecting plates is attached to the surface of the mounting groove.

[0013] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0014] The assembly structure shown in this technical solution utilizes an innovative plug-in / mounting slot design and reinforcement system. Unlike traditional, similarly shaped, adaptable plug-in structures, this solution employs a symmetrical J-shaped plug-in system. The "J"-shaped mounting slots at the top and bottom of the longitudinal plates, along with the "J"-shaped plug-in plates on the base / outer plates, form a symmetrical installation structure. After the long base groove is plugged into the long base, the bent portion and the bent groove are positioned on either side, creating a hollow adjustment space. This design allows for fine-tuning after installation to eliminate dimensional deviations caused by production / transportation errors, effectively avoiding problems such as excessive weld gaps or installation failures. The flexible fixing method of the joint plates further enhances structural adaptability, ensuring a dual improvement in segmented assembly accuracy and assembly efficiency.

[0020] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Example

[0022] refer to Figures 1 to 4 A segmented ship assembly structure includes a frame, a base plate 1 at the bottom of the frame, and an outer plate 2 covering the outer surface of the frame. The long end of the frame is defined as longitudinal and the short end as transverse. The frame is composed of transverse plates 3 and longitudinal plates 4 arranged alternately on the base plate 1. Several mounting grooves 41 are evenly distributed at the upper and lower ends of the longitudinal plates 4. The surfaces of the base plate 1 and the outer plate 2 are provided with insertion plates 5 that can be inserted into the mounting grooves 41. The insertion plate 5 has a "J"-shaped structure with a long base 51 and a bent portion 52 at the end of the long base 51. The mounting groove 41 has a "J"-shaped structure with a long base groove 411 and a bent groove 412 at the end of the long base groove 411.

[0023] When the base plate 1, outer plate 2, and frame are installed, the elongated base 51 of each of the plug-in plates 5 is inserted into the corresponding elongated base groove 411. The bent portion 52 and the bending groove 412 are arranged opposite each other on both sides of the elongated base 51. Each of the longitudinal plates 4 is provided with a connecting plate 6 for fixing the base plate 1 and the outer plate 2. The assembly structure shown in this technical solution, through the innovative plug-in-installation groove 41 matching design and reinforcement system, is different from the traditional adaptable plug-in structure with similar shape. This technical solution is a symmetrical J-type plug-in system. The "J"-shaped installation groove 41 set at the upper and lower ends of the longitudinal plate 4 and the "J"-shaped plug-in plate 5 of the base plate 1 / outer plate 2 form a symmetrical installation structure. After the elongated base groove 411 and the elongated base 51 are inserted, the bent portion 52 and the bending groove 412 are arranged on both sides to form a hollow adjustment space. This design allows for fine-tuning after installation to eliminate dimensional deviations caused by production / transportation errors, effectively avoiding problems such as excessively large weld gaps or inability to install. The flexible fixing method of the joint plate 6 further enhances the structural adaptability, ensuring a dual improvement in segment assembly accuracy and assembly efficiency.

[0024] like Figure 1As shown, the base plate 1 is an integral planar structure, while the outer plate 2 is divided into two plates: a flat plate 2a and an arc-shaped plate 2b. The longitudinal plate 4 at the corresponding installation position of the arc-shaped plate 2b is also arc-shaped. The corresponding mounting grooves 41 are distributed along the arc-shaped edge.

[0025] Structurally, such as Figure 3 As shown, reinforcing members are arranged between adjacent longitudinal plates 4. These reinforcing members include longitudinal sub-plates 42 extending longitudinally and connecting sub-plates 32 connecting the longitudinal sub-plates 42 to each transverse plate 3; or triangular bent plates 43 located between the insert plate 5 and the base plate 1 or outer plate 2. In this embodiment, both are used in combination depending on their location. The combination design of the reinforcing members, consisting of longitudinal sub-plates 42 and connecting sub-plates 32, forms a longitudinally extending reinforcing network between the longitudinal plates 4, significantly improving the overall resistance to deformation. The added triangular bent plate 43 structure forms a triangular stable support between the insert plate 5 and the base plate 1 / outer plate 2, further enhancing the local connection strength, and is particularly suitable for reinforcing high-stress areas.

[0026] In this embodiment, the open end of the elongated base groove 411 is provided with a relief opening 411a. The relief opening 411a provided at the open end of the elongated base groove 411 has a dual function: during the installation stage, it provides a larger insertion guide space and reduces the assembly difficulty; during the welding stage, it serves as a deformation relief zone for the corner welding points, reducing the concentration of welding heat stress, avoiding the risk of local cracking, and improving the stability of welding quality.

[0027] In the specific installation structure, such as Figure 4 As shown, each of the plug-in plates 5 is provided with a plurality of connecting plates 53 distributed longitudinally. Each connecting plate 53 has a connecting groove 531 adapted to the shape of the plug-in plate 5. When the base plate 1, outer plate 2 and frame are installed, each connecting plate 53 is attached to the surface of the mounting groove 41. The longitudinally distributed connecting plates 53, through the design of the connecting groove 531 adapted to the shape of the plug-in plate 5, form a multi-level nested connection structure. During installation, the connecting plates 53 are tightly attached to the surface of the mounting groove 41, which not only increases the longitudinal connection area, but also disperses stress through the stacking effect between the plates, significantly improving the overall shear strength and fatigue durability of the structure.

[0028] In summary, this technical solution solves the problem of precision control in traditional segmented assembly through a plug-in-adjustment mechanism. Combined with the reinforcement system of various strengthening structures, it achieves a full-dimensional technical breakthrough from assembly precision to structural strength, from process optimization to durability improvement. It is particularly suitable for the high-precision and high-reliability assembly requirements in the segmented manufacturing of large ships.
