[0027] It should be noted that during operation, according to the size of the bridge tower cross-section, the bridge tower formwork I-beam frame is erected. The I-beam frame includes a first I-beam frame 1 and a second I-beam frame 2. The erection angle between the first I-beam frame 1 and the second I-beam frame 2 is installed according to requirements. Then, the fixing device 3 is inserted into the splicing gap between the first I-beam frame 1 and the second I-beam frame 2, and then the setting on the fixing device 3 is rotated so that the fixing device 3 fixes the first I-beam frame 1 and the second I-beam frame 2. By adjusting the fixing position of the fixing device 3 from the I-beam frame, the precise splicing and fixing of the bridge tower formwork I-beam frame are realized, thus significantly improving the stability and construction efficiency of the in-situ casting process of the bridge tower formwork. The fixing device 3 can be inserted into the splicing gap between the first I-beam frame 1 and the second I-beam frame 2, which not only realizes the stable connection between the two, but also the connection angle can be adjusted according to actual needs, greatly improving the flexibility and adaptability of the construction.

[0033] In one embodiment, the fixing device 3 includes a second fixing mechanism 32. The second fixing mechanism 32 includes a second upper fixing steel plate 321 arranged at the upper end of the first I-beam frame 1 and a second lower fixing steel plate 322 arranged at the lower end of the second I-beam frame 2. The second upper fixing steel plate 321 and the second lower fixing steel plate 322 are connected by a second screw rod 323. Second fixing nuts 324 are threadedly connected to both sides of the second screw rod 323. A second anti-seismic nut 325 is threadedly connected to the position of the second screw rod 323 outside the second fixing nut 324.
