Description

Technical Field

[0001] This application relates to the technical field of cryogenic liquid storage equipment, and more particularly, 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 storage tank, which poses extremely high requirements for the sealing and structural stability of the storage tank. Traditional anchoring methods often show deficiencies when facing complex environments: When using studs and anchor nuts for fixation, if the studs are not properly designed or the installation process is not standardized, it is easy for the studs to protrude from the surface of the main plywood prematurely. Without appropriate protection measures, the external threads of the exposed studs are extremely vulnerable to damage, and subsequent construction cannot be carried out. Once such a problem occurs, rework is required, resulting in increased costs and extended construction periods. If additional structures are introduced for increased protection, not only will the installation steps become more complex, but it will also cause inconvenience to subsequent maintenance and adjustment. These problems not only affect the normal use of cryogenic thin-film storage tanks but may also lead to an increase in potential safety hazards and maintenance costs, restricting their promotion and use in a wider range of application scenarios.

[0003] In addition, due to the lack of effective internal support measures, when the vacuum pumping operation is carried out, the main layer corrugated board may be concave inward, seriously affecting the sealing performance and the overall structural stability of the storage tank. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems in the prior art that the stud protrudes from the surface of the main plywood prematurely and is easily damaged. For this purpose, this application proposes an embedded anchoring structure.

[0005] An embedded anchoring structure according to an embodiment of this application includes an anchor plate and an anchor nut fixedly connected to the anchor plate. The anchor plate is anchored to the insulation box plywood using rivets. The secondary layer corrugated board is hermetically welded to the anchor plate 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 formed in the main plywood. The lower end of the fixing mechanism passes through the opening and is threadedly connected to the anchor nut. The upper end of the fixing mechanism is welded to the main layer corrugated board to form a main shielding layer.

[0006] Furthermore, a strengthening mechanism for preventing the collapse of the opening is installed in the circular opening formed in the main plywood.

[0007] Furthermore, the fixing mechanism includes an integral stud. The integral stud passes through the opening formed in the main plywood and is threadedly connected to the anchor nut. A nut one and a gasket are connected to the upper end of the integral stud located in the opening. A top cap is threadedly connected to the top end of the integral stud.

[0008] Further, the strengthening mechanism includes a spring washer, and the spring washer is installed between the first nut and the washer.

[0009] Further, the fixing mechanism includes a countersunk bolt. The countersunk bolt passes through the opening formed in the main plywood and is threadedly connected to the anchor nut to press the main plywood tightly. The main laminate nut is inserted into the opening at the upper end of the countersunk bolt and tightened. The main laminate nut and the main corrugated plate are hermetically welded to form a main shielding layer.

[0010] Further, the strengthening mechanism further includes a plywood cover plate, and the plywood cover plate is fixed between the countersunk bolt and the main laminate nut by door nails.

[0011] Further, the fixing mechanism includes an integral bolt. The integral bolt passes through the opening formed in the main plywood and is threadedly connected to the anchor nut.

[0012] Further, a square plate is installed in the opening at the upper end of the integral bolt by rivets. The square plate is on the same horizontal line as the steel plate stamping part, and the square plate is welded to the main corrugated plate.

[0013] Further, the strengthening mechanism includes a steel plate stamping part. The steel plate stamping part is installed at the edge of the opening of the main plywood, and the upper end of the integral bolt is connected to the steel plate stamping part by spot welding.

[0014] Further, the fixing mechanism includes a long stud. The long stud penetrates through the main plywood and is fixedly connected thereto. A circular metal plate is arranged in the opening formed in the main plywood. A second nut is fixedly installed on the lower side of the circular metal plate, and the second nut is threadedly connected to the upper end of the long stud. The upper side of the circular metal plate is welded to the main corrugated plate, and a hexagonal cap is welded to the upper surface of the circular metal plate.

[0015] The beneficial effects of the present application are as follows: The countersunk bolt is used to pass through the opening formed in the main plywood and is threadedly connected to the anchor nut to tightly press 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 corrugated plate are hermetically welded to form a solid main shielding layer. This design adopts the method of separating the countersunk bolt and the main laminate nut to ensure that the countersunk bolt will not protrude from the surface prematurely during the installation process of the main plywood, effectively avoiding the damage of external forces to the anchoring system. In addition, the integral bolt can be used to connect with the anchor nut to realize the stable connection between the steel plate stamping part, the primary and secondary corrugated plates and the main plywood, and the integral bolt is sealed inside by the square plate to further protect the anchoring system from external forces. In addition, the long stud penetrates through the main plywood and is fixedly connected. Its upper end is connected to the circular metal plate through the second nut, not only sealing the long stud in the opening, but also enhancing the stability and sealing performance of the overall structure, effectively preventing the potential damage of external forces to the entire anchoring system, and improving the safety and reliability of the system.

[0016] The beneficial effects of the present application are as follows: After the main layer plywood is fixed, a plywood cover plate is installed in the opening to support the inside of the opening, avoiding the concave phenomenon of the main layer corrugated plate during subsequent vacuum pumping. A spring washer can also be added under the nut one to fill the space between the upper surface of the nut one and the top cap, preventing the main layer corrugated plate from being damaged by extrusion during subsequent tests.

[0029] The following describes an embedded anchoring structure according to an embodiment of the present application with reference to the accompanying drawings.

[0030] As Figures 1 to 7 shown, an embedded anchoring structure according to an embodiment of the present application includes an anchoring plate 3 and an anchoring nut 4 fixedly connected thereto. First, the anchoring plate 3 is firmly fixed to the insulating box plywood 1 by rivets to ensure its firmness. Then, a secondary corrugated plate 5 is hermetically welded to the anchoring plate 3 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 the resistance to external force damage. Subsequently, the main plywood 2 is installed on the constructed secondary shielding layer to further strengthen the integrity of the structure. In particular, a circular opening is provided on the main plywood 2, and a fixing mechanism is installed therein. The lower end of the fixing mechanism passes through the opening and is threadedly connected to the anchoring nut 4 to ensure the reliability and stability of the fixation. To prevent the circular opening from collapsing during use, a special strengthening mechanism is also provided inside the opening. In addition, the upper end of the fixing mechanism is welded to the main layer corrugated plate 9 to jointly form a main shielding layer, further enhancing the protection ability and stability of the entire structure.

[0031] As Figure 1 shown, it is a first embodiment of the fixing mechanism and the strengthening mechanism. The fixing mechanism includes an integral stud 6. The integral stud 6 sequentially passes through the opening in the circular opening on the main plywood 2 and is threadedly connected to the anchoring nut 4 below to complete the longitudinal fixation of the structure. On the integral stud 6 inside the opening, a first nut 7 and a gasket 8 are sequentially arranged along the axial direction to enhance the tightness of the connection part and ensure the surface flatness. The top end of the integral stud 6 is threadedly connected to a top cap 21, thus completing the assembly of the entire fixing structure.

[0032] As Figure 7As shown, specifically, the strengthening mechanism includes a spring washer 11. The spring washer 11 is arranged between the first nut 7 and the washer 8, which plays an elastic pre-tightening and anti-loosening role. At the same time, it forms a local support inside the opening on the main plywood 2 to prevent the collapse of the hole wall caused by uneven stress.

[0033] However, since the integral stud 6 is arranged in an exposed manner, its external threaded part is easily damaged due to external force collision or environmental factors, affecting subsequent disassembly, assembly and maintenance. Therefore, in the following embodiments, the strengthening structure is further optimized to improve the overall durability and structural integrity.

[0034] As Figure 2 shown, this is the second embodiment of the fixing mechanism and the strengthening mechanism, which is used to solve the problem that the exposed thread of the integral stud 6 is easily damaged. Specifically, the fixing mechanism further includes a countersunk head bolt 12, which penetrates the opening on the main plywood 2 and is threadedly connected to the anchoring nut 4 below, thereby firmly pressing the main plywood 2 on the secondary shielding layer to achieve a stable and reliable mechanical connection. It effectively avoids the existence of exposed studs in the traditional structure, makes the connection part integrally embedded inside the main plywood 2, reduces the risk of damage to the thread structure caused by external collision or environmental factors, and improves the safety and aesthetics of the overall structure.

[0035] Furthermore, a main laminate nut 13 is provided at the top of the countersunk head bolt 12. The main laminate nut 13 is inserted into the opening at the upper end of the countersunk head bolt 12 and tightened, so as to perform a sealed 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 on the main plywood 2 to ensure that the surface is flat and without protrusions after installation, avoiding affecting subsequent structure assembly and use safety. This split structure design not only improves the flexibility and operation convenience during installation, but also effectively prevents the countersunk head bolt 12 from protruding from the surface of the main plywood 2 prematurely before being fully assembled, thereby enhancing the safety of the construction process.

[0036] In addition, as Figure 6 shown, to enhance the structural strength at the opening of the main plywood 2 and prevent the collapse of the hole wall due to long-term stress or vibration, the strengthening mechanism in this embodiment further includes a plywood cover plate 10. The plywood cover plate 10 is fixed between the countersunk head bolt 12 and the main laminate nut 13 by door nails, which plays a local reinforcement role and further improves the bearing capacity and structural stability of the opening area.

[0037] In summary, this embodiment not only realizes the embedded arrangement of the anchoring structure by adopting the cooperation structure of the countersunk head bolt 12 and the main laminate nut 13, and combines the plywood cover plate 10 as a strengthening component, improving the overall sealing performance, stability and anti-external force damage ability, but also provides a structural basis and technical support for further optimizing the anchoring form in subsequent embodiments.

[0038] As Figure 3 shown, this is the third embodiment of the fixing mechanism and the strengthening mechanism, which further optimizes the design of the fixing mechanism and the strengthening mechanism. The fixing mechanism further includes an integral bolt 15, which passes through the opening formed 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 by means of a rivet. The square plate 16 is connected to the steel plate stamping part 14 and the main plywood 2 by rivets, and the square plate 16 and the steel plate stamping part 14 are on the same horizontal line, ensuring the consistency and aesthetics of the overall structure. The square plate 16 is welded to the main corrugated plate 9 to form a more compact whole. This method can more effectively protect the internal anchoring system from 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.

[0039] In addition, to enhance the structural strength at the opening of the main plywood 2 and prevent the hole wall from collapsing due to long-term stress or vibration, the strengthening mechanism in this embodiment further includes a steel plate stamping part 14 provided in the opening of the main plywood 2, and the upper end of the integral bolt 15 is connected to the steel plate stamping part 14 by spot welding. This design not only enhances the overall strength and stability of the structure, but also provides additional support by adding the steel plate stamping part 14, making the entire anchoring system more durable and effectively improving the ability to resist external force damage.

[0040] As Figure 4 shown, this is the fourth embodiment of the fixing mechanism. The fixing mechanism further includes a long stud 17, which penetrates through the main plywood 2 and realizes a fixed connection. At the same time, a circular metal plate 18 is provided in the opening formed in the main plywood 2. A second nut 19 is installed on the lower side of the circular metal plate 18, and the second nut 19 is threadedly connected to the upper end of the long stud 17, while the upper side of the circular metal plate 18 is welded to the main corrugated plate 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 the pressure and further improving the stability and compressive resistance of the system.

[0041] As Figure 5As shown, compared with the third embodiment, the fourth embodiment is also unique in that a hexagonal nut 20 is welded to the upper surface of the circular metal plate 18. With the help of tools, it is easy to enter the inside of the hexagonal nut 20 to rotate the circular metal plate 18 and the second nut 19. This design significantly improves the convenience of installation and maintenance, making subsequent adjustments or disassembly more efficient, reducing the construction difficulty and time cost. 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, preventing external forces from damaging the internal components. Therefore, while maintaining the advantages of the third embodiment, the fourth embodiment further optimizes the operational convenience and structural performance.

[0042] The above are only the embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0043] The above are only the specific implementation manners of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
