[0002] Large steel column aerial work platforms are platform structures used to support and carry personnel and equipment working at heights. They are used for the segmented installation of vertical load-bearing steel columns in large and super high-rise steel structure projects. During installation, the upper and lower steel column sections are first hoisted into position, and then the aerial work platform is welded together at high altitude. To ensure worker safety and provide necessary operating space, the work platform is usually installed below the connection point of the steel column.

[0003] Existing large steel column aerial work platforms typically require the design and manufacture of the work platform based on the cross-sectional shape and size of the steel column, and then transport it to the construction site for installation and fixation. When the cross-sectional shape of the steel column is different, such as circular or rectangular steel column, the work platform needs to be redesigned according to the cross-sectional shape and size of the steel column, which not only prolongs the construction period, but also increases the waste of manpower and material resources.
