[0003] For example, a patent document with announcement number CN204139069U discloses a bridge column construction operation platform, including a first bottom plate and a second bottom plate symmetrically arranged; depressions are arranged on the outer sides of the first bottom plate and the second bottom plate; reinforcing ribs are fixedly arranged in the depressions; the first bottom plate and the second bottom plate are respectively integrally formed with a first fixed plate and a second fixed plate at both ends; the first fixed plate and the second fixed plate are fixedly connected by a bolt group running through the first fixed plate and the second fixed plate; a first protective plate is fixedly arranged on the outer periphery of the upper surface of the first bottom plate; a second protective plate is fixedly arranged on the outer periphery of the upper surface of the second bottom plate; this provides a foothold for bridge column construction workers to a large extent, and through the arrangement of the first protective plate and the second protective plate, it plays a good protective role for the construction workers standing on the first bottom plate and the second bottom plate, thereby ensuring the safety of the construction workers.

[0004] Although the above-mentioned support platform can be quickly installed and disassembled, and its position can be changed easily as the construction progresses, the two bottom plates have a large limitation on the diameter of the applicable columns because the diameter of the inner holes cannot be changed. This makes it impossible to use it for columns with different diameters. In actual use, it still has certain inconveniences. Therefore, there is an urgent need for a bridge column construction operation platform to solve the above problems. Utility Model Content

[0008] The anti-skid mechanism is arranged on the top of the semi-ring platform.

[0009] To implement the above technical solution, a threaded rod can be used to push the extrusion strip gradually closer to the column, and multiple extrusion strips can achieve stable clamping of columns with different diameters, and the clamping limit can be released and the clamping limit can be re-clamped quickly. Compared with the prior art, the device can be installed on columns with different diameters, has stronger applicability, and has a simple structure and is easy to repair and maintain.

[0010] Furthermore, the fixing plates close to each other on the two semi-ring platforms are respectively provided with alignment holes and connected with alignment rods, and the alignment holes and the alignment rods cooperate with each other for insertion and positioning.
