[0002] When a cast-in-place bridge structure crosses special areas such as roads, ditches, and ponds, the support system often needs to be set up in the form of a steel pipe column Bailey frame to meet the crossing requirements. Traditional Bailey frames and I-beams are mostly connected by U-shaped locks or welding. When using U-shaped locks, the vibrations during use of the U-shaped locks often cause the screws to loosen, which in turn causes the I-beam to move, and its lateral support strength is low, posing certain safety hazards; and when welding is used, the Bailey bracket and the I-beam will be damaged. Finally, both of the above methods have the disadvantages of low construction efficiency, large material loss, and difficulty in installation and removal.
