[0012] By adopting the above technical solution, a stable frame system is formed by arranging the first steel plate and the second steel plate in the cantilever beam, and arranging a gap and a third steel plate therebetween. This design effectively disperses the force, enhances the stability of the entire structure, enables the connection part to withstand greater external forces and deformations, and thus improves the safety and reliability of the overall structure. The setting of the reinforcement significantly enhances the connection stability between the first steel plate and the second steel plate. The fixed connection between the reinforcement and the steel plate makes the connection part more firm and effectively prevents the connection from loosening or failing due to external forces.

[0015] A second reinforcement plate, which is perpendicularly arranged to the first reinforcement plate, one end of the second reinforcement plate is fixedly connected to the first reinforcement plate, and the other end of the second reinforcement plate is fixedly connected to the side wall of the third steel plate.
[0016] By adopting the above technical solution, the first reinforcement plate is arranged in the gap and fixedly connected to the inner side of the first steel plate, which effectively enhances the connection stability between the first steel plate and the second steel plate. This reinforcement method can prevent the connection from loosening or failing due to external forces or structural deformations. The second reinforcement plate is perpendicularly arranged to the first reinforcement plate and fixedly connected to the side wall of the third steel plate, forming a strong support structure. Enabling the connection part to withstand greater external forces and deformations, significantly improving the connection strength.
[0017] Optionally, 2 reinforcements are symmetrically arranged.

[0025] Optionally, the angle of the first reinforcing rib is greater than the angle of the second reinforcing rib.
[0026] By adopting the above technical solution, since the position of the steel column is at the end of the second steel plate, the distance from the end of the second steel plate to the connection between the steel column and the second steel plate is less than the distance from the connection between the steel column and the second steel plate to the other end of the steel plate. Therefore, the force at the connection between the steel column and the second steel plate to the other end of the steel plate is large, and a larger-angle reinforcing rib is required to provide support and stability.
[0027] Optionally, a connecting plate is fixedly provided at the included angle between the second steel plate and the steel column.
[0028] By adopting the above technical solution, the connecting plate can effectively connect the second steel plate and the steel column firmly together. By increasing the connection area and providing additional support, the strength of the structural connection is significantly improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0037] The following further describes the present application in detail Figures 1 - 3 with reference to the accompanying drawings.
[0038] Combined with Figure 1 and Figure 2, an embodiment of the present application discloses a connecting device between a concrete cantilever beam 12 and a steel column 16, including a main body 11 and a cantilever beam 12. The cantilever beam 12 is firmly arranged at the end of the main body 11. Inside the cantilever beam 12, a first steel plate 13 is provided, and the first steel plate 13 is firmly embedded in the concrete. A second steel plate 14 is also firmly arranged inside the cantilever beam 12. There is a gap 17 between the first steel plate 13 and the second steel plate 14, and this gap 17 provides space for subsequent reinforcement members 2. Inside the gap 17, a third steel plate 15 is vertically arranged. The upper end of the third steel plate 15 is fixedly connected to the inner side of the first steel plate 13 by welding or other reliable means, and the lower end is fixedly connected to the inner side of the second steel plate 14 in the same way. This structure forms a stable support framework, effectively improving the structural strength of the cantilever beam 12. The steel column 16 is arranged at the lower end of the second steel plate 14, and through the firm connection with the second steel plate 14, the stable combination of the steel column 16 and the cantilever beam 12 is realized. In order to further enhance the connection stability between the first steel plate 13 and the second steel plate 14, a reinforcement member 2 is specifically arranged inside the gap 17 in this embodiment.
[0039] Specifically, the first steel plate 13, the second steel plate 14, and the third steel plate 15 are all arranged in the shape of a rectangular plate. The widths of the first steel plate 13 and the second steel plate 14 are equal, and the lengths of the first steel plate 13 and the second steel plate 14 are not specifically limited and can be greater than, less than, or equal to each other. The steel column 16 is formed by fixing two U-shaped steels back to back, that is, the openings of the two U-shaped steels are away from each other. Among them, the first steel plate 13, the second steel plate 14, the third steel plate 15, the reinforcement member 2, and the steel column 16 are fixed before pouring.
[0040] During specific use, before pouring the cantilever beam 12, the first steel plate 13 and the second steel plate 14 are fixed to the pouring frame of the cantilever beam 12 by U-shaped stirrups, and then the cantilever beam 12 is poured. Thus, by reasonably arranging the first steel plate 13, the second steel plate 14, and the third steel plate 15, a stable support framework is formed, enabling the cantilever beam 12 to bear greater loads. At the same time, the introduction of the reinforcement member 2 further improves the stability of the connection point, thereby enhancing the connection strength and stability between the cantilever beam 12 and the steel column 16.
[0041] Combined Figure 2 and Figure 3 , in a specific embodiment, the reinforcement member 2 includes: a first reinforcement plate 21 and a second reinforcement plate 22. The first reinforcement plate 21 is arranged inside the gap 17. The upper end of the first reinforcement plate 21 is fixedly connected to the inner side of the first steel plate 13, and the lower end of the first reinforcement plate 21 is fixedly connected to the inner side of the first steel plate 13. The second reinforcement plate 22 is vertically arranged with respect to the first reinforcement plate 21. One end of the second reinforcement plate 22 is fixedly connected to the first reinforcement plate 21, and the other end of the second reinforcement plate 22 is fixedly connected to the side wall of the third steel plate 15.
[0042] In the embodiment of the present application, the first reinforcing plate 21 and the second reinforcing plate 22 are fixedly connected by welding or bolting, and the first reinforcing plate 21, the second reinforcing plate 22 and the first steel plate 13, the second steel plate 14 and the third steel plate 15 are also fixed in the same way. The fixation of the first reinforcing plate 21 and the second reinforcing plate 22 can increase the stability and load-bearing capacity of the first steel plate 13 and the second steel plate 14, and prevent deformation or damage when subjected to external forces. Specifically, there are 2 reinforcing members 2 symmetrically arranged, respectively on both sides of the gap 17. This symmetrical arrangement can further balance the force on the cantilever beam 12 and prevent structural deformation or damage caused by excessive unilateral force.
[0043] Combined with Figure 2 and Figure 3 , more specifically, in the embodiment of the present application, stud bolts 31 are also fixedly installed at the upper end of the first steel plate 13 and the lower end of the second steel plate 14 respectively. These stud bolts 31 are arranged in an array along the horizontal plane of the first steel plate 13 and the second steel plate 14, effectively increasing the bonding force between the steel plate and the concrete, thereby enhancing the load-bearing capacity of the overall structure.
[0044] Combined with Figure 2 and Figure 3 , in order to further enhance the stability of the connection between the steel column 16 and the cantilever beam 12, in the embodiment of the present application, a first reinforcing rib 32 and a second reinforcing rib 33 are specifically arranged at the included angle between the steel column 16 and the second steel plate 14. Among them, the angle of the first reinforcing rib 32 is set to be greater than the angle of the second reinforcing rib 33. This design can more effectively disperse and transfer the force at the connection, thereby enhancing the durability of the structure.
[0045] Combined with Figure 2 and Figure 3 , in order to further enhance the stability of the connection between the steel column 16 and the cantilever beam 12, in the embodiment of the present application, a first reinforcing rib 32 and a second reinforcing rib 33 are specifically arranged at the included angle between the steel column 16 and the second steel plate 14. Among them, the angle of the first reinforcing rib 32 is set to be greater than the angle of the second reinforcing rib 33. This design can more effectively disperse and transfer the force at the connection, thereby enhancing the durability of the structure. Among them, at the included angle between the second steel plate 14 and the steel column 16, a connecting plate 34 is also fixedly installed in this embodiment. This connecting plate 34 not only increases the connection area, but also forms an overall force-bearing system by firmly connecting it with the surrounding steel plates and the steel column 16, thereby further enhancing the connection strength and stability between the concrete cantilever beam 12 and the steel column 16.
[0046] The implementation principle of the embodiments of this application is as follows: A first steel plate 13, a second steel plate 14, and a third steel plate 15 are arranged in the cantilever beam 12 to form a basic structure for connecting the cantilever beam 12 and the steel column 16. This structural design can ensure that the connection between the cantilever beam 12 and the steel column 16 has sufficient strength and stability. The first reinforcement plate 21 and the second reinforcement plate 22 are respectively arranged in the gap 17 and at a position perpendicular to the third steel plate 15. The first reinforcement plate 21 enhances the connection stability between the first steel plate 13 and the second steel plate 14, while the second reinforcement plate 22 further enhances the integrity and stability of the entire connection structure through its fixed connection with the first reinforcement plate 21 and the third steel plate 15. By fixedly installing stud bolts 31 at the upper and lower ends of the first steel plate 13 and the second steel plate 14, the connection strength and stability between the cantilever beam 12 and the steel column 16 can be further increased. The setting of the stud bolts 31 makes the connection between the steel plate and the concrete closer, and can effectively prevent loosening or falling off at the connection part. The setting of the reinforcing ribs is also an important measure to improve the connection strength and stability. By arranging the first reinforcing rib 32 and the second reinforcing rib 33 at the angle between the steel column 16 and the second steel plate 14, the bearing capacity of this part can be enhanced, and deformation or damage caused by external forces can be prevented.
[0047] This specific embodiment is only an interpretation of this application, and it is not a limitation of this application. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of this application, it is protected by the patent law.
