The laminated wood plate between the support bottom plate and the top surface of the deck base plays a heat insulation and buffering role. The buffer rubber layer between the laminated wood and the top surface of the deck base is mainly used for filling and is not mainly used for fixed connection, and the cracking risk is low.

Description

Technical Field

[0001] This application relates to the technical field of ship design and manufacturing, and more specifically, to a connection structure for a C-type deck tank and a ship thereof. Background Technology

[0002] LPG carriers are vessels specifically designed for transporting cryogenic, volatile liquefied petroleum gas (LPG). As a new type of high-value-added vessel, they enjoy strong market demand. Type C deck tanks, as pressurized containers for ship handling, can be used to load liquefied cargoes, as well as to meet the ship's gas supply system and cargo handling requirements, and are widely used on LPG carriers.

[0003] During ship navigation, external forces can cause the ship to experience buoyancy states such as rolling and pitching, and the cargo loaded in the tanks will also sway. At the same time, for example, the temperature of a Type C deck tank when loading LPG (liquefied petroleum gas) can reach -50°C. Although the deck tank is made of low-temperature steel, it will still experience a certain degree of contraction due to cold.

[0004] Currently, to ensure the stable connection of the C-type deck tank to the hull structure, it's crucial to maintain the tank's stable attachment while allowing it some degree of freedom to accommodate hull deformation and thermal expansion / contraction during navigation. Therefore, the connection between the C-type deck tank and the hull structure is typically achieved through two saddles installed on the deck, one rigidly fixed to the hull and the other sliding. While these two saddles can mitigate the effects of hull deformation and thermal expansion / contraction to some extent, the rigidly connected saddle may fail under prolonged and / or excessive swaying of the C-type deck tank. This can lead to cracking of the epoxy resin sealant at the connection point, posing potential risks to both the deck tank and the ship's operation. Summary of the Invention

[0005] The purpose of this application is to provide a connection structure for a C-type deck tank and a vessel. The connection structure allows the C-type deck tank to be stably attached to the hull structure while also providing a certain degree of freedom to accommodate hull deformation during navigation and the effects of thermal expansion and contraction. The presence of the laminated wood at the connection between the supporting base plate and the connection structure provides insulation and cushioning. Furthermore, the buffer adhesive layer between the laminated wood and the top surface of the deck base is primarily for filling and not for fixing the connection, thus minimizing the risk of cracking.

[0006] In one aspect, a connection structure for a C-type deck tank is provided, wherein the extension direction of the C-type deck tank is defined as longitudinal, and the direction perpendicular to the longitudinal direction and parallel to the horizontal plane is defined as transverse. The connection structure includes a deck base, a first saddle, a second saddle, a first connection structure, and a second connection structure.

[0007] The tops of the first and second saddles are used to install the C-type deck tank:

[0008] A first support base plate is provided below the first saddle, and a second support base plate is provided below the second saddle.

[0009] The deck base is installed on the hull structure, and the top surface of the deck base 100 meets the predetermined flatness requirements;

[0010] The first connecting structure includes a first limiting seat, a first laminated wood board, and a first anti-jumping pressure plate. The first limiting seat is installed on the top surface of the deck base and forms a first limiting groove with the same shape as the first supporting base plate. The first laminated wood board is placed in the first limiting groove, and the gap between the first laminated wood board in the first limiting groove and the top surface of the deck base is filled with a buffer adhesive layer. The upper surface of the first laminated wood board is lower than the opening end face of the first limiting groove of the first limiting seat. The first supporting base plate is placed on the upper surface of the first laminated wood board and embedded in the first limiting groove, and the lower surface of the first laminated wood board is lower than the opening end face of the first limiting groove. The bottom of the first anti-jumping pressure plate is fixedly connected to the top surface of the deck base, and the top is pressed against the upper surface of the first supporting base plate.

[0011] The second connecting structure includes a second limiting seat, a second laminated wood board, and a second anti-jump pressure plate. The second limiting seat is installed on the top surface of the deck base and forms a second limiting groove with the same shape as the second support base plate. The second laminated wood board is placed in the second limiting groove, and the gap between the second laminated wood board in the second limiting groove and the top surface of the deck base is filled with a buffer adhesive layer. The upper surface of the second laminated wood board is higher than the opening end face of the second limiting groove of the second limiting seat. The second support base plate is placed on the upper surface of the second laminated wood board, and the lower surface of the second laminated wood board is lower than the opening end face of the second limiting groove. The bottom of the second anti-jump pressure plate is fixedly connected to the top surface of the deck base, and the top is pressed against the upper surface of the second support base plate.

[0012] In one feasible solution, the depth to which the first support base plate is embedded in the first limiting groove is not less than 1 / 2 of the thickness of the first support base plate.

[0013] In one feasible embodiment, the lower surface of the second support base plate is at least 1 / 3 the thickness of the second laminated wood board above the opening end face of the second limiting groove.

[0014] In one feasible embodiment, both the first and second laminated boards are made of beech wood impregnated with synthetic resin and pressed together at a predetermined temperature and pressure.

[0015] In one feasible approach, the buffer layer is an epoxy resin layer.

[0016] In one feasible embodiment, the number of first anti-jump pressure plates on each of the longitudinal sides of the first support base plate in the first connection structure is greater than or equal to three.

[0017] The number of second anti-jump pressure plates on each of the longitudinal sides of the second support base plate in the second connection structure is greater than or equal to three.

[0018] In one feasible embodiment, the first limiting seat includes two first longitudinal limiting blocks and two first transverse limiting blocks, the first longitudinal limiting blocks and the first transverse limiting blocks forming a first limiting groove.

[0019] The second limiting seat includes two second longitudinal limiting blocks and two second transverse limiting blocks, which together form a second limiting groove.

[0020] In one feasible solution, the first lateral limiting block is L-shaped and includes an integral upright section and a flat section. The upright sections of the two first lateral limiting blocks and the two first longitudinal limiting blocks form a first limiting groove. The upright sections of the two first lateral limiting blocks respectively fit against the side walls of the longitudinal ends of the first supporting base plate, and the flat sections of the two first lateral limiting blocks respectively press against the upper surfaces of the longitudinal ends of the first supporting base plate.

[0021] The second lateral limiting block is L-shaped and includes an integral upright section and a flat section. The upright sections of the two second lateral limiting blocks and the two second longitudinal limiting blocks form a second limiting groove. The upright sections of the two second lateral limiting blocks respectively fit against the side walls at both ends of the longitudinal direction of the second support base plate. The flat sections of the two second lateral limiting blocks respectively press against the upper surfaces at both ends of the longitudinal direction of the second support base plate. The second anti-jump plate presses on the flat section of the second lateral limiting block.

[0022] In one feasible solution, the first anti-jump plate presses against the flat section of the first lateral limiting block;

[0023] The second anti-jump pressure plate presses down on the flat section of the second lateral limit block.

[0024] According to a second aspect of this application, a ship is also provided, including the connection structure of the C-type deck tank in the aforementioned scheme, and further including the C-type deck tank, which is mounted on a first saddle and a second saddle.

[0025] Compared with the prior art, the beneficial effects of this application include at least the following:

[0026] In this application, the first support base plate beneath the first saddle and the first connecting structure form a fixed connection, securing the C-type deck tank to the top surface of the deck base and ensuring the stability of the C-type deck tank during navigation. Simultaneously, the second support base plate beneath the second saddle and the second connecting structure form a sliding connection, allowing one end of the C-type deck tank to retain a certain degree of freedom, mitigating the impact of ship swaying on the C-type deck tank. Furthermore, the C-type deck tank's own thermal expansion and contraction causes significant longitudinal deformation stress, which can be mitigated by the sliding connection between the second support base plate and the second connecting structure, enabling adaptive movement to alleviate the effects of thermal expansion and contraction.

[0027] Meanwhile, in this application, although the laminated wood board between the supporting base plate under the saddle and the top surface of the deck base serves as insulation and cushioning, the buffer adhesive layer filling the gap between the laminated wood board and the top surface of the deck base serves a filling function, not to ensure a firm connection between the laminated wood board and the top surface of the deck base. Therefore, the risk of cracking of the buffer adhesive layer is low, and even if the buffer adhesive layer cracks, it will have virtually no impact on the saddle, whether it is a fixed or sliding connection for the C-type deck tank.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0040] like Figure 1 As shown, this embodiment first provides a connection structure for a C-type deck tank. The extension direction of the C-type deck tank 1 is defined as longitudinal, and the direction perpendicular to the longitudinal direction and parallel to the horizontal plane is defined as transverse. The connection structure of the C-type deck tank includes a deck base 100, a first saddle 2, a second saddle 3, a first connecting structure 4, and a second connecting structure 5. The C-type deck tank 1 is installed on the first saddle 2 and the second saddle 3.

[0041] like Figure 4 As shown, a first support base plate 21 is provided below the first saddle 2. Figure 6 As shown, a second support base plate 31 is provided below the second saddle 3.

[0042] like Figure 2 As shown, the deck base 100 is installed on the hull structure, and the top surface of the deck base 100 meets the predetermined flatness requirements. The deck base 100 is used for leveling, and its structural material can be the same as that of the C-type deck tank 1, for example, both can be made of low-temperature steel.

[0043] like Figure 3a , Figure 4 and Figure 5 As shown, the first connecting structure 4 includes a first limiting seat 41, a first laminated wood board 42, and a first anti-jumping pressure plate 43. The first limiting seat 41 is installed on the top surface of the deck base 100, and the first limiting seat 41 forms a first limiting groove with the same shape as the first supporting base plate 21. The first laminated wood board 42 is placed in the first limiting groove, and the gap between the first laminated wood board 42 in the first limiting groove and the top surface of the deck base 100 is filled with a buffer adhesive layer 6. The upper surface of the first laminated wood board 42 is lower than the opening end face of the first limiting groove of the first limiting seat 41. The first supporting base plate 21 is placed on the upper surface of the first laminated wood board 42 and embedded in the first limiting groove, and the lower surface of the first laminated wood board 42 is lower than the opening end face of the first limiting groove. The bottom of the first anti-jumping pressure plate 43 is fixedly connected to the top surface of the deck base 100, and the top is pressed against the upper surface of the first supporting base plate 21.

[0044] like Figure 3b ,like Figure 6 and Figure 7 As shown, the second connecting structure 5 includes a second limiting seat 51, a second laminated wood board 52, and a second anti-jump pressure plate 53. The second limiting seat 51 is installed on the top surface of the deck base 100, and the second limiting seat 51 forms a second limiting groove with the same shape as the second support base plate 31. The second laminated wood board 52 is placed in the second limiting groove, and the gap between the second laminated wood board 52 in the second limiting groove and the top surface of the deck base 100 is filled with a buffer adhesive layer 6. The upper surface of the second laminated wood board 52 is higher than the opening end face of the second limiting groove of the second limiting seat 51. The second support base plate 31 is placed on the upper surface of the second laminated wood board 52, and the lower surface of the second laminated wood board 52 is lower than the opening end face of the second limiting groove. The bottom of the second anti-jump pressure plate 53 is fixedly connected to the top surface of the deck base 100, and the top is pressed against the upper surface of the second support base plate 31.

[0045] In this embodiment, the first support base plate 21 below the first saddle 2 forms a fixed connection with the first connecting structure 4, which is used to form a stable connection between the C-type deck tank 1 and the top surface of the deck base 100, ensuring the stability of the C-type deck tank 1 during navigation. Meanwhile, the second support base plate 31 below the second saddle 3 forms a sliding connection with the second connecting structure 5, allowing one end of the C-type deck tank 1 to retain a certain degree of freedom, thus mitigating the impact of ship swaying on the C-type deck tank 1. Furthermore, the C-type deck tank 1 itself experiences significant longitudinal deformation stress due to thermal expansion and contraction; this stress can also be mitigated by the sliding connection between the second support base plate 31 and the second connecting structure 5, allowing for adaptive movement to alleviate the effects of thermal expansion and contraction.

[0046] Meanwhile, in this embodiment, although the first support base plate 21 below the first saddle 2 forms a fixed connection with the first connecting structure 4, there is a certain gap between the first laminated wood board 42 and the first limiting seat 41, so that the fixed connection structure formed by the first support base plate 21 and the first connecting structure 4 has a certain buffering capacity, and the fixed connection structure has a certain buffering capacity.

[0047] The laminated wood panels between the supporting base plate and the top surface of the deck base serve as insulation and cushioning.

[0048] Meanwhile, the buffer adhesive layer 6 fills the gap between the first laminated wood board 42 in the first limiting groove and the top surface of the deck base 100, and the buffer adhesive layer 6 fills the gap between the second laminated wood board 52 in the second limiting groove and the top surface of the deck base 100. The buffer adhesive layer 6 here is mainly used for filling and also plays a certain buffering role. The buffer adhesive layer 6 is not mainly used to form a firm fixed connection. Therefore, the risk of cracking of the buffer adhesive layer 6 is low. Even if the buffer adhesive layer 6 cracks, it will not have any impact on the fixed connection or sliding connection saddle of the C-type deck tank.

[0049] It should be noted that the hull structure on which the C-type deck tank 1 is installed may not meet the flatness requirements. Therefore, the deck base 100 is welded to the hull structure, and the top surface of the deck base 100 is used to install the C-type deck tank 1 and its connecting structure.

[0050] It should be further explained that an independent deck base 100 can be installed on the hull structure below the installation positions of the first saddle 2 and the second saddle 3, respectively, and the two deck bases 100 are used for leveling at the positions of the first saddle 2 and the second saddle 3. Alternatively, a larger deck base 100 can be installed on the hull structure below the installation position of the C-type deck tank 1, and this deck base 100 can simultaneously level the installation positions of the first saddle 2 and the second saddle 3.

[0051] In this embodiment, the first saddle 2 and the second saddle 3 are generally made of low-temperature steel.

[0052] In this embodiment, as Figure 4 As shown, the depth to which the first support base plate 21 is embedded in the first limiting groove is not less than 1 / 2 of the thickness of the first support base plate 21.

[0053] In this embodiment, as Figure 6 As shown, the lower surface of the second support base plate 31 is at least 1 / 3 higher than the opening end face of the second limiting groove by the thickness of the second laminated wood board 52.

[0054] In this embodiment, the first laminated wood board 42 and the second laminated wood board 52 are generally made of beech wood impregnated with synthetic resin and pressed under a predetermined temperature and pressure. They not only serve as insulation and heat insulation but also as a buffer, giving the joint a certain degree of flexibility.

[0055] In this embodiment, the buffer layer 6 can be an epoxy resin layer.

[0056] In this embodiment, the number of first anti-jump pressure plates 43 on each side of the longitudinal direction of the first support base plate 21 in the first connecting structure 4 is greater than or equal to three; the number of second anti-jump pressure plates 53 on each side of the longitudinal direction of the second support base plate 31 in the second connecting structure 5 is greater than or equal to three.

[0057] In this embodiment, as Figure 3a , Figure 4 and Figure 5 As shown, the first limiting seat 41 includes two first longitudinal limiting blocks 411 and two first transverse limiting blocks 412, which together form a first limiting groove. In this embodiment, as... Figure 3b , Figure 6 and Figure 7 As shown, the second limiting seat 51 includes two second longitudinal limiting blocks 511 and two second transverse limiting blocks 512, which together form a second limiting groove.

[0058] In this embodiment, as Figure 5 As shown, the first lateral limiting block 412 is L-shaped and includes an integral upright section and a flat section. The upright sections of the two first lateral limiting blocks 412 and the two first longitudinal limiting blocks 411 form a first limiting groove. The upright sections of the two first lateral limiting blocks 412 respectively fit against the side walls of the longitudinal ends of the first support base plate 21, and the flat sections of the two first lateral limiting blocks 412 respectively press against the upper surfaces of the longitudinal ends of the first support base plate 21.

[0059] In this embodiment, as Figure 7As shown, the second lateral limiting block 512 is L-shaped and includes an integral upright section and a flat section. The upright sections of the two second lateral limiting blocks 512 and the two second longitudinal limiting blocks 511 form a second limiting groove. The upright sections of the two second lateral limiting blocks 512 respectively fit against the side walls of the longitudinal ends of the second support base plate 31. The flat sections of the two second lateral limiting blocks 512 respectively press against the upper surfaces of the longitudinal ends of the second support base plate 31. The second anti-jump plate 53 presses on the flat section of the second lateral limiting block 512.

[0060] In this embodiment, the first lateral limiting block 412 is formed into an L-shape including an upright section and a flat section by cold pressing, and the second lateral limiting block 512 is also formed into an L-shape including an upright section and a flat section by cold pressing.

[0061] In this embodiment, as Figure 5 As shown, the first anti-jump plate 43 presses against the flat section of the first lateral limiting block 412. In this embodiment, as... Figure 7 As shown, the second anti-jump pressure plate 53 presses on the flat section of the second lateral limit block 512.

[0062] It should be noted that, unless otherwise specified, the aforementioned components are generally made of low-temperature steel.

[0063] It should be noted that the first saddle 2 includes not only the first supporting base plate 21, but also a top plate, a web plate, side plates, and stiffening plates, etc., and the second saddle 3 includes not only the second supporting base plate 31, but also a top plate, a web plate, side plates, and stiffening plates, etc.

[0064] This embodiment also provides a ship, including the connection structure of the C-type deck tank in the aforementioned scheme.

[0065] This example also provides a construction method for the connection structure of the C-type deck tank in the aforementioned scheme, including:

[0066] First, before hoisting the C-type deck tank 1, the first saddle 2 and the second saddle 3 are installed on the deck tank. The top plate, web plate, bottom plate, side plates and stiffening plates of the saddles (first saddle 2 and second saddle 3) are installed in sequence from top to bottom. During installation, the verticality of the web plate is strictly controlled, and the flatness of the bottom plate (first support bottom plate 21 and second support bottom plate 31) and the installation tolerance between the two supports should meet the predetermined specifications.

[0067] The second step is to weld a deck base 100 made of low-temperature steel onto the hull structure after the hull structure is completed. This is for leveling purposes, and the flatness of the top surface of the deck base 100 must be strictly controlled. All installation tolerances must meet the predetermined specifications.

[0068] The third step is to weld two first longitudinal limiting blocks 411 of the first limiting seat 41 of the first connecting structure 4 to the top surface of the deck base 100, and weld two second longitudinal limiting blocks 511 of the second limiting seat 51 of the second connecting structure 5 to the top surface of the deck base 100.

[0069] The fourth step is to install a first laminated wood board 42 between the two first longitudinal limiting blocks 411 and fill the gap with epoxy resin adhesive. The upper surface of the first laminated wood board 42 is lower than the upper surface of the two first longitudinal limiting blocks 411.

[0070] Fifth step, install the second laminated wood board 52 between the two second longitudinal limiting blocks 511 and fill the gap with epoxy resin adhesive. The top surface of the second laminated wood board 52 should be about 1 / 3 of the board thickness higher than the upper surface of the two second longitudinal limiting blocks 511. After installation, the flatness of the upper surface of the laminated wood should meet the predetermined specifications.

[0071] Step 6: Hoist the C-type deck tank 1. The two saddles of the C-type deck tank are hoisted onto the first laminated wood board 42 and the second laminated wood board 52 respectively. The deck tank support base plate at the fixed connection is embedded in the groove formed by the two first longitudinal limiting blocks 411 and pressed on the upper surface of the laminated wood. The depth of the first support base plate 21 under the first saddle 2 embedded in the groove should not be less than 1 / 2 of its own thickness and should be in contact with the inner side of the two first longitudinal limiting blocks 411. The second support base plate 31 under the second saddle 3 is pressed on the second laminated wood board 52 and is in contact with the upper surface of the second laminated wood board 52.

[0072] Step 7: Install L-shaped first lateral limiting blocks 412 on both longitudinal sides of the first support base plate 21 below the first saddle 2, and install L-shaped second lateral limiting blocks 512 on both longitudinal sides of the second support base plate 31 below the second saddle 3. The bottom of the upright section of the lateral limiting block is in contact with the top surface of the deck base 100, and the flat section is in contact with the upper surface of the support base plate and then welded in place.

[0073] Step 8: Install first anti-jump plates 43 on both longitudinal sides of the first support base plate 21 below the first saddle 2, and install second anti-jump plates 53 on both longitudinal sides of the second support base plate 31 below the second saddle 3. The anti-jump plates are then welded to the top surface of the deck base 100 and the upper surface of the transverse limiting block. Furthermore, the number of first anti-jump plates 43 on each longitudinal side of the first support base plate 21 in the first connecting structure 4 is greater than or equal to three; the number of second anti-jump plates 53 on each longitudinal side of the second support base plate 31 in the second connecting structure 5 is greater than or equal to three. The deck tank installation is complete.

[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
