Description

Background technique

In super high-rise buildings, often due to the building shape, the external frame columns need to be retracted through the inclined columns, so climbing frames need to be used. When the traditional climbing frame encounters retraction and changes in cross-section, it is common to replace one or more sides of the climbing frame. The method is to perform adduction, that is, the climbing frame in the adducted area stops at the variable cross-section, and the climbing frame is reassembled at the lower part. During the structural construction, cantilevered scaffolding is used. This alternative method will produce many shortcomings.
