Description

Technical Field

[0001] This utility model relates to the field of steel plate splicing technology, and in particular to an environmentally friendly, highly corrosion-resistant galvanized bent steel plate splicing and fixing structure. Background Technology

[0002] Environmentally friendly, high-corrosion-resistant galvanized bent steel sheets are made from ordinary steel sheets that have undergone environmentally friendly galvanizing processes and then bent into shape. By splicing and fixing multiple environmentally friendly, high-corrosion-resistant galvanized bent steel sheets, the size and shape of the sheets can be flexibly adjusted to realize the construction of various large and complex building structures or industrial facilities.

[0003] A search of Chinese patent publication number "CN215254550U" reveals "A composite steel splicing and fixing structure." This structure uses built-in double-headed bolts to engage with splicing blocks on the first and second steel plates, splicing them together. First and second sealing rings on the first and second steel plates seal the splice seam. A built-in bending splicing part enables right-angle splicing of the third steel plate, with second and third sealing rings on the second and third steel plates again sealing the splice seam. This effectively solves the technical problems of existing composite steel splicing methods, such as cumbersome operation and difficulty in ensuring a seal between splice seams.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. However, when splicing steel plates, the splicing and fixing structure mainly relies on fixing plates and bolts to complete the indirect connection between the two steel plates. Therefore, there is a lack of rigid connection between the steel plates, resulting in insufficient overall strength after connection, which needs to be improved. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an environmentally friendly, highly corrosion-resistant galvanized bent steel plate splicing and fixing structure, which solves the technical problem of insufficient strength after connection of existing splicing and fixing structures.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An environmentally friendly, high corrosion-resistant galvanized bent steel plate splicing and fixing structure includes a first environmentally friendly, high corrosion-resistant galvanized bent steel plate body and a second environmentally friendly, high corrosion-resistant galvanized bent steel plate body.

[0010] Both the upper end of the first environmentally friendly high corrosion-resistant galvanized bent steel plate body and the lower end of the second environmentally friendly high corrosion-resistant galvanized bent steel plate body are provided with splicing and fixing structures.

[0011] The splicing and fixing structure includes a raised L-shaped snap-fit ​​layer. Both of the raised L-shaped snap-fit ​​layers have rounded corner grooves on their outer sides. Multiple first threaded grooves are opened through the first environmentally friendly high corrosion-resistant galvanized bent steel plate body and the second environmentally friendly high corrosion-resistant galvanized bent steel plate body. Each first threaded groove is opened at an angle. A first fixing plate is provided at the lower end of the first environmentally friendly high corrosion-resistant galvanized bent steel plate body. A second fixing plate is provided at the upper end of the second environmentally friendly high corrosion-resistant galvanized bent steel plate body. Multiple hexagonal grooves are opened inside the first fixing plate and the second fixing plate. Multiple threaded rods are provided between the two first fixing plates and the second fixing plate.

[0012] Preferably, each of the threaded rods is threadedly installed inside the first threaded groove, and each of the threaded rods has a first nut threadedly installed at both ends. Each first nut is located inside a hexagonal groove, and a plurality of first connecting blocks are fixedly installed on the side wall of the first fixing plate.

[0013] Preferably, a plurality of second connecting blocks are fixedly installed on the side wall of the second fixing plate, and screws are provided between each first connecting block and the second fixing plate, as well as between each second connecting block and the first fixing plate, and a second nut is threaded onto the threaded end of each screw.

[0015] (III) Beneficial Effects

[0016] Firstly, by opening inclined first threaded grooves in the first and second environmentally friendly high corrosion-resistant galvanized bent steel plate bodies, when the threaded rod is tightened, the first and second environmentally friendly high corrosion-resistant galvanized bent steel plate bodies and the threaded rod form a Z-shaped fastening. The Z-shaped fastening method can change the force transmission path.

[0024] This application provides an environmentally friendly, high-corrosion-resistant galvanized bent steel plate splicing and fixing structure, effectively solving the technical problem of insufficient strength after connection in existing splicing and fixing structures. By opening an inclined first threaded groove in the first and second environmentally friendly, high-corrosion-resistant galvanized bent steel plate bodies, a Z-shaped fastening is formed between the first and second environmentally friendly, high-corrosion-resistant galvanized bent steel plate bodies and the threaded rod when the threaded rod is tightened. The Z-shaped fastening method can change the force transmission path.

It can better resist tensile and shear forces, enabling the connection parts to withstand greater loads, reducing the possibility of loosening or damage due to stress, and further improving the fastening performance. By setting a first connecting block and a second connecting block, and setting screws to connect the first connecting block and the first fixing plate, as well as the second connecting block and the second fixing plate, through the second thread groove of the first environmentally friendly high corrosion-resistant galvanized bent steel plate body and the second environmentally friendly high corrosion-resistant galvanized bent steel plate body respectively, it is possible to further reinforce both sides of the Z-shaped fastening shape formed by the second thread groove and threaded rod of the first environmentally friendly high corrosion-resistant galvanized bent steel plate body and the second environmentally friendly high corrosion-resistant galvanized bent steel plate body, thereby greatly improving the strength of this splicing and fixing method.

[0025] Example

[0026] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem of insufficient strength after connection of existing splicing and fixing structures. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides an environmentally friendly, high corrosion-resistant galvanized bent steel plate splicing and fixing structure, including a first environmentally friendly, high corrosion-resistant galvanized bent steel plate body 11 and a second environmentally friendly, high corrosion-resistant galvanized bent steel plate body 12.

[0028] The upper end of the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11 and the lower end of the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12 are both provided with splicing and fixing structures.

[0029] The splicing and fixing structure includes a raised L-shaped snap-fit ​​layer 13. Both raised L-shaped snap-fit ​​layers 13 have rounded corner grooves 14 on their outer sides. At the same time, the rounded corners provide a smooth transition, making it easier for the adhesive to spread evenly, reducing air bubbles and unfilled areas, further improving the effect of auxiliary fixing and enhancing the firmness.

[0030] By setting up a splicing and fixing structure, a rounded corner groove 14 is provided on the outside of the L-shaped snap-fit ​​layer 13, so that workers can stick the adhesive inside the rounded corner groove 14.

[0031] Multiple first threaded grooves 15 are provided through the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11 and the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12. Each first threaded groove 15 is inclined. A first fixing plate 16 is provided at the lower end of the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11. A second fixing plate 17 is provided at the upper end of the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12. Multiple hexagonal grooves 18 are provided inside the first fixing plate 16 and the second fixing plate 17. Multiple threaded rods 19 are provided between the two first fixing plates 16 and the second fixing plate 17. The two ends of the threaded rods 19 extend to the outside of the first fixing plates 16 and the second fixing plates 17. Each threaded rod 19 is threaded inside the first threaded groove 15. A first nut 21 is threaded at both ends of each threaded rod 19. Each first nut 21 is located inside the hexagonal groove 18.

[0032] By opening inclined first threaded grooves 15 in the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11 and the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12, when the threaded rod 19 is tightened, the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11 and the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12 and the threaded rod 19 form a Z-shaped fastening. The Z-shaped fastening method can change the force transmission path. When subjected to external force, the inclined contact surface between the threaded rod 19 and the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11 and the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12 can better resist tensile and shear forces, enabling the connection part to withstand greater loads, reducing the possibility of loosening or damage to the connection due to force, and further improving the fastening performance.

[0033] Multiple first connecting blocks 22 are fixedly installed on the side wall of the first fixing plate 16, and multiple second connecting blocks 23 are fixedly installed on the side wall of the second fixing plate 17. Each first connecting block 22 and the second fixing plate 17, as well as the second connecting block 23 and the first fixing plate 16, are provided with screws 24. Each screw 24 has a second nut 25 threaded at the end of its thread. Multiple second threaded grooves 26 are opened through the interior of the first environmentally friendly high corrosion resistant galvanized bent steel plate body 11 and the second environmentally friendly high corrosion resistant galvanized bent steel plate body 12. Each screw 24 is located inside the second threaded groove 26 and threaded.

[0034] By setting a first connecting block 22 and a second connecting block 23, and setting screws 24 to connect the first connecting block 22 and the first fixing plate 16, as well as the second connecting block 23 and the second fixing plate 17 through the second threaded groove 26 of the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11 and the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12, the Z-shaped fastening shape formed by the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11, the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12, and the threaded rod 19 can be reinforced on both sides, thereby greatly improving the strength of this splicing and fixing method. At the same time, due to the use of threaded connection and bonding, the problem of damage to the galvanized coating on the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11 and the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12 caused by the high temperature generated during welding can be avoided.

[0035] Working principle:

[0036] The first step is to align the raised L-shaped snap-fit ​​layer on the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12 with the raised L-shaped snap-fit ​​layer inside the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11. After alignment, adhesive can be applied between the rounded corner grooves 14 on the outside of the two L-shaped snap-fit ​​layers 13 for auxiliary bonding.

[0037] First, after the auxiliary pasting is completed, the worker can place the first fixing plate 16 under the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11 and the second fixing plate 17 above the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12. The threaded rod 19 is passed between the first fixing plate 16 and the second fixing plate 17, and the first threaded groove 15 must be located inside the first threaded groove 15. Then, the worker can connect the first nut 21 to both ends of the threaded rod 19 until the first nut 21 is located inside the hexagonal groove 18, thereby completing the connection between the first environmentally friendly high corrosion-resistant galvanized bent steel plate body 11 and the second environmentally friendly high corrosion-resistant galvanized bent steel plate body 12.

[0038] In the third step, the workers can pass the screws 24 between the first connecting block 22 and the first fixing plate 16, and between the second connecting block 23 and the second fixing plate 17, and finally use the second nut 25 to fix them, thus completing the installation.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
