Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cryogenic liquid cargo storage equipment, and in particular to an embedded anchoring structure. Background Art
[0002] During the storage of cryogenic liquids, specific pressure and temperature conditions need to be maintained inside the tank, which places extremely high demands on the sealing and structural stability of the tank. Traditional anchoring methods often show shortcomings when facing complex environments:
[0003] When using studs and anchor nuts for fixing, if the studs are improperly designed or the operation is not standardized during the installation process, it is easy for the studs to protrude from the surface of the main plywood prematurely. Without proper protection measures, the exposed external threads of the studs are easily damaged and subsequent construction cannot be carried out. Once this problem occurs, rework is required, resulting in increased costs and extended construction periods. If additional structures are introduced to increase protection, it will not only make the installation steps more complicated, but also bring inconvenience to subsequent maintenance and adjustments. These problems not only affect the normal use of low-temperature membrane storage tanks, but may also lead to increased safety hazards and increased maintenance costs, limiting their promotion and use in a wider range of application scenarios.
[0004] In addition, due to the lack of effective internal support measures, when the vacuum operation is carried out, the main layer corrugated plate may become concave, seriously affecting the sealing performance of the storage tank and the stability of the overall structure. Summary of the Invention
[0005] The present application aims to solve at least one of the technical problems in the prior art, that is, the studs protrude prematurely from the main plywood surface and are easily damaged. To this end, the present application proposes an embedded anchoring structure.
[0006] According to an embodiment of the present application, an embedded anchoring structure includes an anchoring plate and an anchoring nut fixedly connected to the anchoring plate. The anchoring plate is anchored to the plywood of the insulation box using rivets. The secondary corrugated plate and the anchoring plate are seal-welded to form a secondary shielding layer. The main plywood is installed on the secondary shielding layer. A fixing mechanism is installed in a circular opening on the main plywood. The lower end of the fixing mechanism passes through the opening and is threadedly connected to the anchoring nut. The upper end of the fixing mechanism is welded to the main corrugated plate to form a main shielding layer.
[0007] Furthermore, a reinforcing mechanism for preventing the circular opening from collapsing is installed in the circular opening formed on the main plywood.
[0008] Furthermore, the fixing mechanism includes an integrated stud, which passes through an opening opened in the main plywood and is threadedly connected to an anchor nut. The upper end of the integrated stud located in the opening is connected to a nut and a gasket, and the top end of the integrated stud is threadedly connected to a top cap.
[0009] Furthermore, the reinforcing mechanism includes a spring washer, which is installed between nut 1 and the washer.
[0010] Furthermore, the fixing mechanism includes a countersunk bolt, which passes through an opening in the main plywood and is threadedly connected to an anchor nut to press the main plywood. The main laminate nut is inserted into the opening at the upper end of the countersunk bolt and tightened. The main laminate nut is sealed and welded to the main layer corrugated plate to form a main shielding layer.
[0011] Furthermore, the reinforcement mechanism also includes a plywood cover plate, which is fixed between the countersunk bolts and the main laminate nuts through door-type nails.
[0012] Furthermore, the fixing mechanism includes an integral bolt, which passes through an opening formed in the main plywood and is threadedly connected to an anchor nut.
[0013] Furthermore, a square plate is installed in the opening at the upper end of the integral bolt through a rivet, the square plate and the steel plate stamping part are on the same horizontal line, and the square plate is welded to the main layer corrugated plate.
[0014] Furthermore, the reinforcing mechanism includes a steel plate stamping part, which is installed on the edge of the opening of the main plywood, and the upper end of the integrated bolt is connected to the steel plate stamping part by spot welding.
[0015] Furthermore, the fixing mechanism includes a long stud, which passes through the main plywood and is fixedly connected to it. A circular metal plate is provided in the opening of the main plywood. Nut 2 is fixedly installed on the lower side of the circular metal plate. Nut 2 is threadedly connected to the upper end of the long stud. The upper side of the circular metal plate is welded to the main layer corrugated plate, and a hexagonal screw cap is welded on the upper surface of the circular metal plate.
[0016] The beneficial effects of the present application are as follows: a countersunk bolt is passed through the openings in the main plywood and threadedly connected to the anchor nut to compress and fix the main plywood. At the same time, the main laminate nut is inserted into the opening at the upper end of the countersunk bolt and tightened, so that the main laminate nut and the main layer corrugated plate are sealed and welded to form a solid main shielding layer. This design uses a separate countersunk bolt and main laminate nut to ensure that the countersunk bolt does not protrude from the surface prematurely during the installation of the main plywood, effectively preventing external forces from damaging the anchoring system. In addition, the integrated bolt and anchor nut connection can be used to achieve a stable connection between the steel plate stamping, the primary and secondary corrugated plates, and the main plywood, and the integrated bolt is sealed inside by the square plate to further protect the anchoring system from external forces. In addition, a long stud is passed through the main plywood and fixedly connected, and its upper end is connected to the circular metal plate by nut 2, which not only seals the long stud in the opening, but also enhances the stability and sealing of the overall structure, effectively preventing potential damage to the entire anchoring system by external forces, and improving the safety and reliability of the system.
[0017] The beneficial effects of this application are as follows: after the main layer of plywood is fixed, a plywood cover is installed in the opening to support the inside of the opening, thereby preventing the main layer of corrugated board from concaving during subsequent vacuuming. A spring washer can also be added under the nut to fill the space between the upper surface of the nut and the top cap, thereby preventing the main layer of corrugated board from being squeezed and damaged during subsequent testing.
[0018] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become obvious from the description below, or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] An embedded anchoring structure according to an embodiment of the present application is described below with reference to the accompanying drawings.
[0037] like Figures 1 to 7 As shown, an embedded anchoring structure according to an embodiment of the present application includes an anchor plate 3 and an anchor nut 4 fixedly connected thereto. First, the anchor plate 3 is firmly fixed to the insulation box plywood 1 using rivets to ensure its firmness. Next, the secondary corrugated plate 5 and the anchor plate 3 are sealed and welded to form a reliable secondary shielding layer. This design not only significantly enhances the stability and sealing performance of the overall structure, but also greatly improves its resistance to external forces. Subsequently, the main plywood 2 is installed on top of the constructed secondary shielding layer to further strengthen the integrity of the structure. In particular, a circular opening is opened in the main plywood 2, in which a fixing mechanism is installed. The lower end of the fixing mechanism passes through the opening and is threadedly connected to the anchor nut 4, ensuring the reliability and stability of the fixation. To prevent the circular opening from collapsing during use, a special reinforcement mechanism is also provided inside the opening. In addition, the upper end of the fixing mechanism is welded to the main corrugated plate 9, together forming the main shielding layer, further enhancing the protection capability and stability of the entire structure.
[0038] like Figure 1As shown, this is a first embodiment of a fixing and reinforcement mechanism. The fixing mechanism includes an integrated stud 6, which passes through the circular openings in the main plywood 2 and is threadedly connected to the anchor nut 4 below to complete the longitudinal fixation of the structure. A nut 7 and a washer 8 are axially positioned on the integrated stud 6 within the opening to enhance the tightness of the connection and ensure surface flatness. The top end of the integrated stud 6 is threadedly connected to a cap 21, completing the assembly of the entire fixing structure.
[0039] like Figure 7 As shown, specifically, the reinforcing mechanism includes a spring washer 11, which is arranged between the nut 7 and the washer 8, and plays the role of elastic pre-tightening and anti-loosening, and at the same time forms a local support for the inside of the opening on the main plywood 2 to prevent the hole wall from collapsing due to uneven force.
[0040] However, since the integrated stud 6 is exposed, its external threaded portion is easily damaged by external force collision or environmental factors, affecting subsequent disassembly and maintenance. To this end, the structure is further optimized and strengthened in the following embodiments to improve overall durability and structural integrity.
[0041] like Figure 2 As shown, this is a second embodiment of the fixing mechanism and the reinforcing mechanism, which is used to solve the problem that the above-mentioned integrated stud 6 is exposed and the thread is easily damaged. Specifically, the fixing mechanism also includes a countersunk bolt 12, which passes through the opening on the main plywood 2 and is threadedly connected to the anchor nut 4 below, thereby firmly pressing the main plywood 2 on the secondary shielding layer to achieve a stable and reliable mechanical connection, effectively avoiding the existence of exposed studs in traditional structures, so that the connecting part is embedded in the main plywood 2 as a whole, reducing the risk of damage to the threaded structure due to external collisions or environmental factors, and improving the safety and aesthetics of the overall structure.
[0042] Furthermore, a main laminate nut 13 is provided on the top of the countersunk bolt 12. The main laminate nut 13 is inserted into the opening at the upper end of the countersunk bolt 12 and tightened to perform a sealing welding between it and the main layer corrugated plate 9 to form a continuous and stable main shielding layer. At the same time, the top end of the main laminate nut 13 covers the opening above the main plywood 2 to ensure that the surface is flat and free of protrusions after installation, thereby avoiding affecting the subsequent structural assembly and safety of use. This split structural design not only improves the flexibility and ease of operation during the installation process, but also effectively prevents the countersunk bolt 12 from protruding from the surface of the main plywood 2 prematurely before it is fully assembled, thereby enhancing the safety of the construction process.
[0043] In addition, if Figure 6As shown, in order to enhance the structural strength of the opening of the main plywood 2 and prevent the hole wall from collapsing due to long-term stress or vibration, the reinforcement mechanism in this embodiment also includes a plywood cover plate 10. The plywood cover plate 10 is fixed between the countersunk bolt 12 and the main laminate nut 13 by a door-shaped nail, which plays a role of local reinforcement and further improves the bearing capacity and structural stability of the opening area.
[0044] In summary, this embodiment adopts the matching structure of the countersunk bolt 12 and the main laminate nut 13, and combines the plywood cover 10 as a reinforcing component, which not only realizes the embedded arrangement of the anchoring structure, improves the overall sealing, stability and resistance to external force damage, but also provides a structural basis and technical support for further optimization of the anchoring form in subsequent embodiments.
[0045] like Figure 3 As shown, this is the third embodiment of the fixing mechanism and the reinforcing mechanism, which further optimizes the design of the fixing mechanism and the reinforcing mechanism. The fixing mechanism also includes an integral bolt 15, which passes through the opening opened in the main plywood 2 and is threadedly connected to the anchor nut 4. In addition, a square plate 16 is installed in the opening at the upper end of the integral bolt 15 through a rivet. The square plate 16 is connected to the steel plate stamping 14 and the main plywood 2 through the rivet, and the square plate 16 and the steel plate stamping 14 are located on the same horizontal line, ensuring the consistency and aesthetics of the overall structure. The square plate 16 is welded to the main layer corrugated plate 9 to form a tighter whole. This method can more effectively protect the internal anchoring system from the influence of the external environment, extend the service life, and significantly enhance the safety and reliability of the entire system. Therefore, while maintaining the advantages of the second embodiment, the third embodiment further optimizes the structural performance and provides more comprehensive protection measures.
[0046] Furthermore, to enhance the structural strength of the opening in the main plywood 2 and prevent the hole wall from collapsing due to prolonged stress or vibration, the reinforcing mechanism in this embodiment also includes a steel plate stamping 14 positioned within the opening in the main plywood 2. The upper end of the integral bolt 15 is spot-welded to the steel plate stamping 14. This design not only enhances the overall strength and stability of the structure, but also provides additional support through the addition of the steel plate stamping 14, making the entire anchoring system more robust and durable, effectively improving its resistance to external damage.
[0047] like Figure 4As shown, this is a fourth embodiment of the fixing mechanism, which also includes a long stud 17 that penetrates the main plywood 2 and secures the connection. A circular metal plate 18 is positioned within the opening in the main plywood 2. A second nut 19 is mounted on the underside of the circular metal plate 18 and is threadedly connected to the upper end of the long stud 17. The upper side of the circular metal plate 18 is welded to the main corrugated sheet 9. This design not only enhances the overall strength of the structure but also provides a larger contact area through the circular metal plate 18, thereby dispersing pressure and further improving the stability and pressure resistance of the system.
[0048] like Figure 5 As shown, compared with the third embodiment, the uniqueness of the fourth embodiment is that a hexagonal screw cap 20 is welded to the upper surface of the circular metal plate 18. With the help of tools, the interior of the hexagonal screw cap 20 can be easily entered to rotate the circular metal plate 18 and the nut 19. This design significantly improves the convenience of installation and maintenance, makes subsequent adjustments or disassembly more efficient, and reduces construction difficulty and time costs. In addition, the use of the circular metal plate 18 not only enhances the sealing effect, but also provides additional protection for the entire anchoring system to prevent external forces from damaging internal components. Therefore, while maintaining the advantages of the third embodiment, the fourth embodiment further optimizes the operational convenience and structural performance.
[0049] The above are merely examples of the present application and are not intended to limit the scope of protection of the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application. It should be noted that similar numbers and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined or explained in subsequent figures.
[0050] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
