Especially when facing complex structures such as long-span cable-stayed bridges, the steel anchor beam technology shows significant advantages in the construction of such bridges due to its high efficiency and adaptability. It not only improves the construction efficiency but also is particularly suitable for the construction of bridges in complex terrain areas, thereby ensuring the smoothness and safety of traffic.

[0003] The following problems will be encountered in the construction process of the upper cross beam of the tower column steel pipe truss:

The sliding frame 45 is slidably arranged along the height direction of the tower column 2 along the special-shaped groove track 46. The steel pipe truss 16 is placed and tied above the sliding frame 45.

[0040] In some embodiments, special-shaped steel channels 3 are fixedly arranged inside the tower column 2. The two ends of the bracket 1 are embedded into the special-shaped steel channels 3 to achieve sliding. The positions of two rows of special-shaped steel channels 3 are determined according to the positioning of the steel pipe truss and the size of the bracket on the already constructed tower column. After the special-shaped steel channels 3 are closely attached to the tower column, they are fixed to the tower column 2.

[0041] In some embodiments, the special-shaped steel channels 3 are arranged inside the tower column 2 and are arranged at a position close to the bottom of the tower column 2.
