[0027] In this embodiment, a plurality of hinged rods 10 are connected between the upper wing plate 2 and the connecting plate 1 8 by bolts and screws, a plurality of hinged rods 2 13 are connected between the lower wing plate 1 and the connecting plate 2 9 by bolts and screws, and a reinforcing rib 4 is symmetrically provided on the lower wing plate 1, one end of the reinforcing rib 4 is fixedly connected to the outer end of the lower wing plate 1, and the other end of the reinforcing rib 4 is fixedly connected to the outer wall of the corrugated steel web 3, and a connecting rod 5 is connected between the middle part of the reinforcing rib 4 and the lower wing plate 1, and a plurality of oblique rods 11 and oblique rods 2 12 are provided between the connecting plate 1 8 and the connecting plate 2 9, and the oblique rods 11 and the oblique rods 2 12 are staggered, and the symmetrically arranged corrugated steel webs 3 can be realized through the positioning assembly. The fast and stable connection between the two corrugated steel webs 3 improves the connection strength between the two corrugated steel webs 3, making it less likely for the corrugated steel webs 3 to become unstable and bend, thereby improving the shear resistance of the corrugated steel web box girder. Through the cooperation of the hinged rod 10, the hinged rod 2 13, the diagonal rod 1 11, the diagonal rod 2 12, the reinforcing rib 4 and the connecting rod 5, the corrugated steel web 3 can be stably supported to prevent the corrugated steel web 3 from becoming unstable and bending when the bridge is under pressure, thereby improving the stability of the device, and having the effects of improving the connection strength and shear resistance, stable support, anti-bending and reliable safety. Among them, through the staggered diagonal rod 1 11 and the diagonal rod 2 12, a stable connection between the connecting plate 1 8 and the connecting plate 2 9 can be achieved.

[0028] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 3 The positioning assembly includes a positioning hole 14, which is arranged at one end of the connecting plate 8 and the connecting plate 9 close to the connecting slide 7; an installation box 15, which is arranged on the side of the mounting seat 15 away from the corrugated steel web 3, and a positioning slide 16 is slidably provided in the installation box 15, one end of the positioning slide 16 passes through the installation box 15 and movably cooperates with the positioning hole 14, and the other end of the positioning slide 16 passes through the installation box 15 and is connected to a counterweight block 17 movably arranged on the outside of the installation box 15; an inclined groove 20, which is arranged in the positioning slide 16; a push rod 18, which is slidably arranged in the installation box 15, one end of the push rod 18 is provided with a sliding column 19 slidably cooperated with the inclined groove 20, and the other end of the push rod 18 passes through the installation box 15.
