Description

Technical Field

[0001] This invention relates to the field of ship structure technology, and in particular to a transition structure for connection with the top of a stack compartment and its installation method. Background Technology

[0002] The T-shaped structure at the top of the dam is usually installed at regular intervals, typically 1000mm apart. If the T-shaped structure is set as a right angle, it will not be conducive to stress release under temperature and pressure loads. Moreover, the T-shaped structure plate is usually thick, which can easily cause tearing of the structural deck connected to the T-shaped structure. Therefore, considering the stress concentration problem, the connection positions of the four walls of the dam are usually connected in an arc shape.

[0003] For the top structure of the refrigeration tank, since the T-shaped panels are of an arc-shaped structure, special design is required at the connection points to ensure they can connect with the deck structure and achieve the same structural strength and rigidity. Furthermore, because the outer walls of the refrigeration tank structure often require shielding material, the areas where the reinforcing panels are installed cannot be completely sealed off; space must be reserved for installation, construction, and future maintenance. Summary of the Invention

[0004] The main objective of this invention is to provide a transition structure and its installation method for connection with the top of the sump, which aims to facilitate connection with the deck while retaining the arc structure of the T-shaped profile at the top of the sump.

[0005] To achieve the above objectives, the present invention provides a transition structure for connection with a spool, comprising a transition deck for connecting the deck plate and the area between the top of the spool and the deck plate, and a support elbow plate supported on the bottom of the transition deck facing the spool. The transition deck near the spool has a shape that complements the T-shaped panel of the spool. The support elbow plate includes a support elbow plate panel and a support elbow plate web plate arranged perpendicular to it. The bottom end face of the support elbow plate web plate is connected to the top arc surface of the spool, and the side end face of the support elbow plate web plate is connected to the support elbow plate panel. The transition deck is also provided with deck beams, deck longitudinal girder and deck longitudinal ribs. The side of the support elbow plate panel away from the spool is connected to the deck longitudinal girder through a reinforcing elbow plate.

[0006] Preferably, adjacent support elbow plates are connected by a reinforcing plate, and the top surface of the reinforcing plate is connected to the bottom surface of the transition deck.

[0007] Preferably, the reinforcing plate is made of flat steel, and the height of the reinforcing plate is greater than the height of the longitudinal ribs of the deck.

[0008] Preferably, the reinforcing plate is provided with reinforcing ribs.

[0009] Preferably, the width of the support elbow plate panel and the T-shaped panel of the stack bin are equal.

[0010] Preferably, the deck girder and deck rib terminate on the support elbow plate panel or reinforcing plate.

[0011] Preferably, each T-shaped profile in the stack bin is provided with a corresponding support elbow plate.

[0012] Preferably, the top surface of the reinforcing elbow plate is connected to the bottom surface of the deck girder, and the side surface of the reinforcing elbow plate is connected to the side surface of the supporting elbow plate panel.

[0013] Preferably, the width of the support elbow plate panel is greater than the width of the deck longitudinal girder.

[0014] The present invention further proposes an installation method based on the above-described transition structure for connection with a storage bin, comprising the following steps: A support elbow plate web is welded above each T-shaped curved panel of the stack bin. A transition deck is installed above the support elbow plate web. One side of the transition deck is connected to the top T-shaped panel of the stack bin. The gap between the transition deck and the T-shaped panel is filled by welding to ensure that the two are at the same height. After installing the support elbow plate panel on the side of the web of each support elbow plate, weld the adjacent support elbow plate panels together by means of a reinforcing plate. Install the support elbow plate on the side of the support elbow plate panel, install the deck plate, and finally install the deck girder, deck beam and deck rib.

[0015] The transition structure proposed in this invention for connection with the refrigeration tank features a simple connection structure. Each supporting elbow plate corresponds one-to-one with a T-shaped member of the refrigeration tank structure, resolving the termination issue of deck structure components and ensuring effective stress transfer. Simultaneously, the gaps between the T-shaped members of the refrigeration tank structure are preserved, providing installation and maintenance space for shielding materials. The spatial layout of its structural components is rational, facilitating subsequent maintenance. Furthermore, while ensuring the continuity of the deck structure, the construction process of the transition structure is convenient and feasible. Attached Figure Description

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] This invention proposes a transition structure for connection with a stack compartment.

[0022] Reference Figures 1 to 3 In this preferred embodiment, a transition structure for connection with the spool includes a transition deck 1 for connecting the deck plate 2 and the area between the top of the spool 10 and a support elbow plate supported on the bottom of the transition deck 1 facing the spool, wherein... The transition deck 1, on the side closest to the spool, has a shape complementary to the T-shaped panel 11 of the spool. The supporting elbow plate includes a supporting elbow plate panel 4 and a supporting elbow plate web 3 perpendicularly thereto. The bottom end face of the supporting elbow plate web 3 connects to the top arc surface of the spool, and the side end face of the supporting elbow plate web 3 connects to the supporting elbow plate panel 4. Below the transition deck 1, deck beams 7, deck longitudinal girder 5, and deck longitudinal stiffeners 8 are also provided. The side of the supporting elbow plate panel 4 facing away from the spool is connected to the deck longitudinal girder 5 via a reinforcing elbow plate 6. The supporting elbow plate web 3 and the supporting elbow plate panel 4 are arranged perpendicularly.

[0023] Figure 1In the design, the left side of the transition deck 1 is straight, while the right side is curved to complement the shape of the T-shaped profile 11 panel of the refrigeration tank. To prevent stress concentration, the corners of the refrigeration tank are rounded, and the external reinforcing T-shaped profile 11 also adopts a ring structure. In this case, when the deck structure is connected to the top reinforcing structure of the refrigeration tank, the termination end of the lower deck component needs to be set as a free end, which is not conducive to stress transmission. Therefore, the transition deck 1 is set between the T-shaped profile 11 panels on the outer wall of the refrigeration tank and in the rounded gap at the top. One end of the transition deck 1 is connected to the deck structure, and the other end is prefabricated with a complementary shape according to the distribution of the T-shaped profile 11 panels at the top of the refrigeration tank. It is then welded to the T-shaped profile 11 panels at the top of the refrigeration tank by embedding, forming the complete deck surface.

[0024] Furthermore, referring to Figure 1 and Figure 3 The two adjacent support elbow plate panels 4 are connected by a reinforcing plate 9, and the top surface of the reinforcing plate 9 is connected to the bottom surface of the transition deck 1 (welding connection can be used).

[0025] By connecting the two adjacent support elbow plate panels 4 with the reinforcing plate 9, the structure can have the necessary strength and rigidity, and the stress can be effectively transferred and released.

[0026] Specifically, in this embodiment, the reinforcing plate 9 is made of flat steel, and the height of the reinforcing plate 9 is greater than the height of the deck longitudinal rib 8.

[0027] Furthermore, referring to Figure 3 The reinforcing plate 9 is equipped with reinforcing ribs, which further improves the structural strength and stability of the overall transition structure.

[0028] In this embodiment, the support elbow plate panel 4 and the T-profile 11 panel of the stack bin have the same width. The T-profile 11 structure at the top of the stack bin is usually set at regular intervals, typically 1000mm apart. Similarly, the support elbow plate panel 4 is also spaced out like the T-profile 11.

[0029] In this embodiment, the deck longitudinal girder 5 (spacing is generally 2000mm) and the deck longitudinal rib 8 (spacing is generally 500mm) terminate on the support elbow plate panel 4 or the reinforcing plate 9, thereby ensuring the effective transmission of stress.

[0030] Furthermore, referring to Figure 1 Each T-shaped section 11 in the stacker is equipped with a corresponding supporting elbow plate. Specifically, the top surface of the reinforcing elbow plate 6 is connected to the bottom surface of the deck longitudinal girder 5, and the side surface of the reinforcing elbow plate 6 is connected to the side surface of the supporting elbow plate panel 4. The reinforcing elbow plate 6 can be a triangular plate. The width of the supporting elbow plate panel 4 is greater than the width of the deck longitudinal girder 5.

[0031] The installation method for this transition structure used for connection with the storage bin is as follows: 1. A support elbow plate web 3 is welded above each T-profile 11 arc panel of the stack bin. A transition deck 1 is installed above the support elbow plate web 3. One side of the transition deck 1 is connected to the top T-profile 11 panel of the stack bin. The gap between the transition deck 1 and the T-profile 11 panel is filled by welding to ensure that the two are at the same height. 2. After installing the support elbow plate panel 4 on the side of each support elbow plate web 3, weld the two adjacent support elbow plate panels 4 together with the reinforcing plate 9. 3. Install the support elbow plate on the side of the support elbow plate panel 4, install the deck plate 2 (the deck plate 2 and the transition deck 1 are connected by butt welding), and finally install the deck longitudinal girder 5, deck beam 7 and deck longitudinal rib 8.

[0032] The transition structure proposed in this invention for connection with the refrigeration tank features a simple connection structure. Each supporting elbow plate corresponds one-to-one with the T-shaped profile 11 of the refrigeration tank structure, resolving the termination issue of deck structure components and ensuring effective stress transfer. Simultaneously, the gaps between the T-shaped profiles 11 of the refrigeration tank structure are preserved, providing installation and maintenance space for the shielding material. Its structural component spatial layout is rational, facilitating subsequent maintenance. Furthermore, while ensuring the continuity of the deck structure, the construction process of the transition structure is convenient and feasible. The present invention further proposes an installation method for a transition structure connected to a pod.

[0033] Reference Figure 4 In this preferred embodiment, an installation method based on the above-described transition structure for connection with the storage bin includes the following steps: Step S10: A support elbow plate web 3 is welded above each T-profile 11 arc panel of the stack bin. A transition deck 1 is installed above the support elbow plate web 3. One side of the transition deck 1 is connected to the top T-profile 11 panel of the stack bin. The gap between the transition deck 1 and the T-profile 11 panel is filled by welding to ensure that the two are at the same height. Step S20: After installing the support elbow plate panel 4 on the side of each support elbow plate web 3, weld two adjacent support elbow plate panels 4 together by means of a reinforcing plate 9. Step S30: Install the support elbow plate on the side of the support elbow plate panel 4, install the deck plate 2, and finally install the deck longitudinal girder 5, deck crossbeam 7 and deck longitudinal rib 8.

[0034] The installation method proposed in this invention is simple and easy to operate, and has the advantage of high construction efficiency.

[0035] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
