[0002] In the traditional process of pouring concrete in steel pipe columns, for steel pipe columns with corbels (such as beam-column joints, etc.), it is usually only necessary to insert the steel structure operation platform into the steel pipe column and place it on the corbels to form an auxiliary operation platform for subsequent concrete pouring construction in steel pipe columns; for steel pipe columns without corbels (such as beam-column joints, etc.), steel pipes or disc buckle frames are usually used to build from the bottom of the column to the construction surface, which is used as an auxiliary operation platform for subsequent concrete pouring construction in steel pipe columns. However, there are some problems with the above-mentioned traditional construction method for setting up auxiliary operation platforms for steel pipe columns without corbels. First, for steel pipe columns without corbels, starting from the bottom of the column to build from steel pipes or disc buckle frames to the construction surface, not only the workload is large, but also the construction period is long and the efficiency is low. Secondly, the auxiliary operation platform set up has poor stability and is prone to shaking during the pouring process, affecting the construction quality. In addition, the auxiliary operation platform of the steel pipe or disc buckle frame needs to be removed after the pouring is completed, and the removal work is cumbersome and easy to cause damage to the steel pipe column.
