Triangular frames 2 are fixedly installed at the front end and the rear end of the connecting frame 1, and the triangular frames 2 are fixedly installed on the top of the steel frame 3.

[0029] By installing the steel frame 3 in the connecting groove 101, since the shape of the connecting groove 101 is exactly the same as the appearance of the steel frame 3, the steel frame 3 can be embedded into the connecting frame 1. By installing the first installation screw 106 and the second installation screw 108, the steel frame 3 can be stably installed in the connecting frame 1, ensuring the firmness of the connection, enabling multi-point fixation of the bridge structure, thereby enhancing the stability and load-bearing capacity of the overall structure.

[0030] After the steel frame 3 is installed inside the connecting frame 1, install the third installation screw 202 in the third installation hole 303. By using the triangular frame 2, the stress can be effectively dispersed, avoiding structural fatigue and damage caused by stress concentration, extending the service life of the structure, and improving the stability of the structure, increasing the anti-deformation ability of the connecting frame 1.

[0031] A second limiting hole 104 corresponding to the first limiting hole 102 is provided inside the limiting frame 103, and a third limiting hole 105 is provided inside the limiting frame 103.

[0038] A third mounting screw 202 is installed on the inner wall thread of the fourth limiting hole 201, and the tripod 2 and the steel frame 3 are fixedly installed through the third mounting screw 202.

[0039] After the steel frame 3 is installed inside the connecting frame 1, since the tripod 2 is installed on the top of the steel frame 3, the fourth limiting hole 201 will match the first mounting hole 301. By turning the third mounting screw 202 and installing it in the third mounting hole 303, the connection between the connecting frame 1 and the tripod 2 can be further strengthened. With the design of the tripod 2, it can maintain its shape unchanged when bearing external loads and provide a strong support.

[0040] The implementation principle of a steel structure bridge connector in the embodiment of this application is as follows: by installing the steel frame 3 in the connecting groove 101, since the shape of the connecting groove 101 exactly matches the appearance of the steel frame 3, the steel frame 3 can be embedded in the connecting frame 1. By using the limiting frame 103, it is ensured that it will not shift or shake during the installation process, guaranteeing the overall structural stability and alignment accuracy of the connector. By using the threads on the inner wall of the first limiting hole 102, the second limiting hole 104 and the first mounting hole 301, turn the first mounting screw 106 and install it inside the steel frame 3 and the connecting frame 1, and install a flat washer 107 on the other side of the first mounting screw 106, which can increase the contact area and disperse the pressure, helping to keep the first mounting screw 106 stable;

[0041] After the first mounting screw 106 is installed, the second mounting hole 302 will exactly match the third limiting hole 105. By using the threads on the inner wall of the third limiting hole 105 and the second mounting hole 302, and turning the second mounting screw 108, it can be installed in the second mounting hole 302, and the steel frame 3 can be stably installed in the connecting frame 1, ensuring the firmness of the connection, enabling multi-point fixation of the bridge structure, and thus enhancing the overall structural stability and load-bearing capacity;

[0042] After the steel frame 3 is installed inside the connecting frame 1, since the triangular frame 2 is installed on the top of the steel frame 3, the fourth limiting hole 201 will match the first installation hole 301. By screwing the third installation screw 202 and installing it in the third installation hole 303, the connection between the connecting frame 1 and the triangular frame 2 can be further strengthened. With the design of the triangular frame 2, it can maintain its shape unchanged when bearing external loads, provide strong support, and effectively disperse stress, avoiding stress concentration at a certain point, thereby reducing the risk of structural fatigue and fracture, extending the service life of the structure, and improving the stability of the structure.
