Abstract
Description
Technical Field
[0001] This invention relates to the field of corrosion protection technology for marine spherical space frames and spherical components, specifically to a composite anti-corrosion buckle and its manufacturing and usage methods. Background Technology
[0002] As a crucial structure in offshore construction and marine engineering, marine spherical space frames are highly susceptible to corrosion and rust at their bolted connections (especially the gaps between the bolt sleeves and the upper cone and lower sphere). These connections are exposed to harsh environments of high salt spray, high humidity, and strong ultraviolet radiation, which in turn affects the stability and service life of the space frame structure. Current corrosion protection methods primarily include traditional anti-corrosion sleeves, anti-corrosion coating spraying, general-purpose clip protection, or manual application of anti-corrosion tape.
[0003] However, traditional anti-corrosion sleeves are mostly one-piece structures, which are difficult to fit together and do not fit tightly with the bolt bushings, cones, and spheres, easily creating gaps that allow salt spray and moisture to penetrate, resulting in poor anti-corrosion performance. Anti-corrosion coatings have complex spraying processes, low construction efficiency, and the coatings are prone to peeling and aging, leading to high subsequent maintenance costs. General-purpose anti-corrosion clips are not designed for the special structure of offshore spherical space frames and cannot accurately fit the gaps between the bolt bushings and the upper cones and lower spheres, creating blind spots in protection. Furthermore, the locking structure is simple and has poor adaptability, making it difficult to meet the stable protection requirements of high-vibration environments at sea. The method of manually wrapping anti-corrosion tape relies entirely on manual operation, which is not only extremely inefficient but also results in inconsistent tightness and coverage, leading to poor uniformity. Loose wrapping can create gaps, while overly tight wrapping can damage the tape, both of which lead to unstable anti-corrosion performance and the inability to form a uniform and reliable anti-corrosion sealing layer. At the same time, the high labor costs make it difficult to meet the anti-corrosion construction needs of large-scale offshore space frames. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the problems of the prior art and provide a composite anti-corrosion buckle and its manufacturing and use method, so as to solve the problems of poor anti-corrosion effect of bolt connection parts of existing marine spherical grid structures, low efficiency and poor consistency of manual wrapping of anti-corrosion tape.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0006] A composite anti-corrosion buckle includes a buckle assembly and an anti-corrosion bonding layer. The buckle assembly includes a left half-clamp body and a right half-clamp body. One end of the left half-clamp body is hinged to one end of the right half-clamp body by a pin. The other end of the left half-clamp body is locked and fixed to the other end of the right half-clamp body by a locking buckle. The anti-corrosion bonding layer is applied to the left half-clamp body and the right half-clamp body.
[0007] Furthermore, the anti-corrosion bonding layer is applied to the inner ring and upper and lower ends of the left half of the clamp and the right half of the clamp, so as to achieve full bonding between the snap-fit assembly and the bolt bushing and its adjacent upper cone and lower sphere in the marine spherical grid, thereby improving the anti-corrosion and sealing effect.
[0008] Furthermore, the anti-corrosion bonding layer is applied to the inner ring of the left and right halves of the clamp, and the upper and lower ends of the anti-corrosion bonding layer extend beyond the upper and lower end faces of the left and right halves of the clamp. The dimension of the portion extending beyond the upper end face of the left and right halves of the clamp matches the gap dimension between the upper end face of the bolt bushing and the lower end face of the upper cone in the marine spherical space frame; the dimension extending beyond the lower end face of the left and right halves of the clamp matches the gap dimension between the lower end face of the bolt bushing and the upper end face of the lower sphere in the marine spherical space frame, ensuring that the anti-corrosion bonding layer can accurately fill the connection gap and eliminate protection dead angles.
[0009] Furthermore, the left half of the clamp body is provided with a first connecting platform with a pin hole at one end, and the right half of the clamp body is provided with a second connecting platform with a pin hole at one end, which is also provided with a pin hole. When the left half of the clamp body and the right half of the clamp body are engaged, the first connecting platform and the second connecting platform are offset from each other and are set at the same center. The pin shaft passes through the corresponding pin hole to hinge one end of the left half of the clamp body and one end of the right half of the clamp body, thereby enabling both the left half of the clamp body and the right half of the clamp body to rotate around the pin shaft, realizing the flexible opening and closing of the buckle assembly, which is convenient for fitting and disassembling.
[0010] Furthermore, the locking buckle includes a card provided at the other end of the left half of the clamp body and a slot provided at the other end of the right half of the clamp body; the side wall of the card is integrally formed with elastic teeth, and the inner side of the elastic teeth is provided with a wedge-shaped adjustment groove. When fastening, the card is inserted into the slot, and the wedge-shaped adjustment groove and the wedge surface of the slot are pressed together to achieve stable fastening. At the same time, the deformation reaction force of the elastic teeth achieves self-locking, ensuring that the buckle assembly does not loosen in the vibration environment at sea.
[0011] Furthermore, the locking buckle includes a locking block at one end of the left half of the clamp body and an opening groove at one end of the right half of the clamp body. When the left half of the clamp body and the right half of the clamp body are locked together, the locking block is directly inserted into the opening groove. The interference fit between the locking block and the opening groove achieves a tight fit and locks the clamp, ensuring that there is no loosening after locking and adapting to different locking requirements. Furthermore, the gap between the inner ring of the left half of the clamp body and the bolt bushing, as well as the gap between the upper and lower ends of the left half of the clamp body and the adjacent upper cone and lower ball, are smaller than the thickness of the anti-corrosion bonding layer. After the buckle is tightened, the anti-corrosion bonding layer is pressed and precisely bonded to the upper cone and lower ball ends adjacent to the bolt bushing, which plays a waterproof and sealing role and effectively prevents the penetration of corrosive media such as salt spray and moisture.
[0012] Furthermore, the anti-corrosion bonding layer is an anti-corrosion adhesive tape, which is a salt spray resistant and highly adhesive anti-corrosion structure. It is tightly adhered to the inner ring and upper and lower end faces of the left half of the clamp and the right half of the clamp through its own adhesiveness, which is suitable for the highly corrosive marine environment and is tightly adhered and not easy to fall off.
[0013] Furthermore, the aforementioned anti-corrosion tape can also be bonded to the clip assembly using a special adhesive primer to further improve the adhesion.
[0014] Furthermore, the left and right halves of the clamp are made of modified PP material that is resistant to UV aging and salt spray corrosion, or other modified materials that are resistant to UV aging and salt spray corrosion. They are formed by injection molding or 3D printing. The dimensions of the left and right halves of the clamp match the corresponding bolt and bushing specifications. The use of modified PP material not only provides excellent resistance to salt spray and UV aging, but is also environmentally friendly and biodegradable. At the same time, it is lightweight and will not increase the load on the space frame structure.
[0015] A method for manufacturing a composite anti-corrosion buckle, applicable to the aforementioned composite anti-corrosion buckle, includes the following steps:
[0016] S1. Molding: The left half of the clamp and the right half of the clamp are respectively made of modified PP material that is resistant to UV aging and salt spray corrosion or other modified materials that are resistant to UV aging and salt spray corrosion, and are produced by injection molding or 3D printing to ensure that the clamp structure is complete, the dimensions are accurate, and the specifications of the bolt bushing are met.
[0017] S2. Surface pretreatment and connection: The inner rings and upper and lower end faces of the left half of the clamp and the right half of the clamp are polished and degreased; and the left half of the clamp and the right half of the clamp are hinged together by a pin.
[0018] S3. Applying anti-corrosion tape: Apply the anti-corrosion tape to the inner ring and upper and lower end faces of the left half of the clamp and the right half of the clamp using its own adhesive properties, and press it with a roller at a pressure of 0.3-0.5MPa to remove air bubbles and wrinkles, ensuring a tight fit and that the anti-corrosion tape can fully cover the inner ring and upper and lower ends of the clamp.
[0019] S4. Trimming: After application, use a utility knife to trim any excess anti-corrosion tape from the edges. During trimming, avoid damaging the buckle assembly and the anti-corrosion bonding layer. Ensure that the size of the anti-corrosion tape is completely matched with the inner ring and end of the left half of the clamp and the right half of the clamp, so as not to affect the buckle engagement and locking effect.
[0020] S5. Apply primer to the anti-corrosion tape: Apply a protective primer with adhesive properties evenly to the inner ring and ends of the left and right halves of the clamp body after the anti-corrosion tape has been applied, so that it can be tightly attached to the bolt surface and the ends of the connecting parts on both sides of the bolt during construction and installation.
[0021] A method for using a composite anti-corrosion buckle, applied to the aforementioned composite anti-corrosion buckle, includes the following specific steps:
[0022] S1. Buckle inspection: Confirm that the anti-corrosion bonding layer of the composite anti-corrosion buckle is not detached or damaged, and that the buckle components move flexibly to ensure that the buckle can be used normally;
[0023] S2. Bolt cleaning: Clean the surface of the bolts and the gaps at both ends that require anti-corrosion sealing, remove surface dust, oil, and rust, and ensure that the bolt surface is dry and free of impurities to avoid impurities affecting the bonding effect and anti-corrosion performance of the anti-corrosion bonding layer;
[0024] S3. Snap-fit engagement: Open the locking buckle of the snap-fit assembly; fit the left and right halves of the clamp onto the bolt sleeve, ensuring that the anti-corrosion bonding layer is completely aligned with the outer surface of the bolt sleeve, the lower end face of the upper cone at the upper end of the bolt sleeve, and the upper end face of the lower ball at the lower end, covering all gaps and eliminating blind spots in protection;
[0025] S4. Locking and fixing: The buckle and locking components are fastened together. The squeezing force of the buckle components is used to tightly fill the anti-corrosion bonding layer into the circumferential gap of the bolt bushing, forming an anti-corrosion sealing layer and achieving all-round anti-corrosion sealing.
[0026] S5. Subsequent maintenance: When maintaining the equipment, open the buckle assembly and check the condition of the buckle assembly or the anti-corrosion bonding layer; if it is intact, reassemble and use it; if it is damaged, replace the buckle assembly or reapply the anti-corrosion bonding layer to reduce maintenance costs and extend service life.
[0027] The beneficial effects of this invention are as follows:
[0028] 1. This invention addresses the special structural design of marine spherical grid structures by employing two anti-corrosion bonding layer application methods. This not only meets the basic anti-corrosion requirements but also precisely adapts to the gaps between the bolt bushing and the upper cone and lower sphere, eliminating blind spots in protection and effectively solving the problem of easy corrosion of bolted connections in high-salt spray environments at sea. It is suitable for highly corrosive and high-vibration marine environments.
[0029] 2. In this invention, a salt spray-resistant, high-adhesion anti-corrosion adhesive tape is used as the anti-corrosion bonding layer, which is tightly applied to the inner ring and upper and lower ends of the clamp. After the clips are tightened, the anti-corrosion adhesive tape is pressed and precisely bonded to the bolt bushing, upper cone, and lower ball to form a complete anti-corrosion sealing layer, effectively blocking the penetration of corrosive media such as salt spray and moisture. At the same time, the clamp body is made of modified PP material that is resistant to UV aging and salt spray corrosion, or other modified materials that are resistant to UV aging and salt spray corrosion, further improving the overall anti-corrosion performance and service life.
[0030] 3. The present invention adopts a left and right half-clamp hinge structure to achieve flexible opening and closing, and facilitate fitting and disassembly; it is equipped with two replaceable locking methods (card + slot self-locking, card block + open slot interference locking) which can be selected according to actual needs to ensure stable locking, prevent loosening in marine vibration environment, and adapt to the locking requirements of bolts and bushings of different specifications.
[0031] 4. This invention completely abandons the traditional method of manually wrapping anti-corrosion tape. It adopts standardized injection molding and precise application processes to produce buckles that can be directly fitted and locked, eliminating the need for manual point-by-point wrapping. This significantly improves the construction efficiency of anti-corrosion of offshore grid structure bolts and reduces labor costs. At the same time, standardized production ensures that the structural dimensions of each buckle and the application accuracy of the anti-corrosion adhesive layer are consistent, resulting in uniform and stable locking force and anti-corrosion sealing effect. This effectively solves the problem of inconsistent anti-corrosion effects caused by uneven tightness and coverage of manual wrapping, significantly improving the consistency and reliability of anti-corrosion quality.

[0046] Example 1:
[0047] A composite anti-corrosion buckle includes a buckle assembly and an anti-corrosion bonding layer. The buckle assembly includes a left half clamp body 1 and a right half clamp body 2. Both the left half clamp body 1 and the right half clamp body 2 are made of modified PP material that is resistant to UV aging and salt spray corrosion or other modified materials that are resistant to UV aging and salt spray corrosion. They are produced by injection molding or 3D printing, and their dimensions match the specifications of the corresponding bolt bushing 11.
[0048] One end of the left half of the clamp body 1 is provided with a first connecting platform 3 with a pin hole, and one end of the right half of the clamp body 2 is provided with a second connecting platform 4 with a pin hole. When the left half of the clamp body 1 and the right half of the clamp body 2 are clamped together, the first connecting platform 3 and the second connecting platform 4 are offset and set at the same center. The pin shaft 5 passes through the corresponding pin hole and hinges one end of the left half of the clamp body 1 and the right half of the clamp body 2, so that both the left half of the clamp body 1 and the right half of the clamp body 2 can rotate around the pin shaft 5.
[0049] The other end of the left half of the clamp body 1 is provided with a card 6, and the other end of the right half of the clamp body 2 is provided with a slot 7. The side wall of the card 6 is integrally formed with elastic teeth, and the inner side of the elastic teeth is provided with a wedge-shaped adjustment groove. The card 6 and the slot 7 form a locking buckle.
[0050] The anti-corrosion bonding layer is a salt spray resistant, high-adhesion anti-corrosion adhesive tape 8, which is applied to the inner ring and upper and lower ends of the left half of the clamp body 1 and the right half of the clamp body 2. It is tightly bonded by its own adhesiveness, without bubbles or wrinkles.
[0051] The manufacturing method of the composite anti-corrosion buckle in this embodiment includes the following steps:
[0052] S1. Molding: The left half of the clamp body 1 and the right half of the clamp body 2 are respectively made of modified PP material that is resistant to UV aging and salt spray corrosion or other modified materials that are resistant to UV aging and salt spray corrosion, and are produced by injection molding or 3D printing to ensure structural integrity and dimensional accuracy.
[0053] S2. Surface pretreatment and connection: Grind and degrease the inner rings and upper and lower end faces of the left half clamp body 1 and the right half clamp body 2 to remove surface burrs and oil stains; Hinge the left half clamp body 1 and the right half clamp body 2 together through the pin 5.
[0054] S3. Apply anti-corrosion tape 8: Apply the anti-corrosion tape 8 to the inner ring and upper and lower ends of the left half clamp body 1 and the right half clamp body 2 using its own adhesiveness, and press it with a roller at a pressure of 0.3MPa to remove air, ensuring tight adhesion, no air bubbles, and no wrinkles;
[0055] S4. Trimming: Use a utility knife to trim any excess anti-corrosion fastening strip 8 from the edges, ensuring that the size of the anti-corrosion fastening strip 8 is completely matched with the inner ring and end of the clamp, without affecting the snap-fit and locking effect.
[0056] S5. Apply primer to the anti-corrosion tape: Apply a protective primer with adhesive properties evenly to the inner ring and ends of the left and right halves of the clamp body after the anti-corrosion tape has been applied, so that it can be tightly attached to the bolt surface and the ends of the connecting parts on both sides of the bolt during construction and installation.
[0057] Before use, first check the fasteners: confirm that the anti-corrosion fastening strip 8 is not detached or damaged, that the left half of the clamp 1 and the right half of the clamp 2 rotate flexibly around the pin 5, and that the clip 6 and the slot 7 fit smoothly; then clean the surface of the bolt sleeve 11 of the offshore spherical space frame and the gaps at both ends to remove dust, oil, and rust, ensuring the surface is dry and free of impurities; then open the clip 6 and the slot 7, and fit the left half of the clamp 1 and the right half of the clamp 2 onto the bolt sleeve 11, ensuring that the anti-corrosion fastening strip 8 fits snugly against the outer surface of the bolt sleeve 11. The lower end face of the upper cone 12 and the upper end face of the lower sphere 13 are completely aligned, covering all gaps. Finally, the card 6 is inserted into the card slot 7. Through the wedge adjustment groove and the wedge surface of the card slot 7, the elastic card teeth deform and generate a reaction force to achieve self-locking. The squeezing force of the buckle assembly tightly adheres the anti-corrosion strip 8 to each contact surface, forming an anti-corrosion sealing layer. During subsequent maintenance, the buckle assembly is opened to check the condition of the anti-corrosion strip 8 and the buckle assembly. If they are intact, they can be reassembled for use. If they are damaged, the anti-corrosion strip 8 or the buckle assembly should be replaced.
[0058] Example 2:
[0059] The difference between this embodiment and Embodiment 1 is that the structure of the locking buckle is different, while the rest of the structure, manufacturing method and usage method are the same as in Embodiment 1.
[0060] In this embodiment, the locking buckle includes a locking block 9 provided at the other end of the left half of the clamp body 1 and an opening groove 10 provided at the other end of the right half of the clamp body 2. The locking block 9 and the opening groove 10 are interference fit. When fastened, the locking block 9 is directly inserted into the opening groove 10 to achieve tight fit and lock, ensuring that there is no loosening after fastening.
[0061] Example 3:
[0062] The difference between this embodiment and Embodiment 1 is that the application method of the anti-corrosion bonding layer is different, while the rest of the structure, manufacturing method and usage method are the same as in Embodiment 1.
[0063] In this embodiment, the anti-corrosion tape 8 is applied to the inner ring of the left half of the clamp 1 and the right half of the clamp 2, with its upper and lower ends extending beyond the upper and lower end faces of the left half of the clamp 1 and the right half of the clamp 2. The size of the portion extending beyond the upper end face matches the gap size between the upper end face of the bolt sleeve 11 and the lower end face of the upper cone 12 in the marine spherical space frame, and the size of the portion extending beyond the lower end face matches the gap size between the lower end face of the bolt sleeve 11 and the upper end face of the lower sphere 13. After the buckle is tightened, the inner ring anti-corrosion tape 8 is compressed to fill the gap, and the anti-corrosion tape 8 extending beyond the end face adheres to the bolt sleeve 13 and the upper cone 12 and the lower sphere 13 under the squeezing action, so that the end of the bolt sleeve 13 is precisely bonded to the upper cone 12 and the lower sphere 13, further improving the sealing and anti-corrosion effect.
[0064] Example 4:
[0065] The difference between this embodiment and Embodiment 3 is that the structure of the locking buckle is different, while the rest of the structure, manufacturing method and usage method are the same as in Embodiment 3.
[0066] In this embodiment, the locking buckle adopts an interference fit structure between the locking block 9 and the opening slot 10 (same as in embodiment two).
