Abstract
Description
Technical Field
[0001] This utility model relates to the field of temporary support installation technology for cantilever frames, and in particular to a combined temporary support structure for cantilever frames. Background Technology
[0002] In prefabricated buildings, the exterior walls are precast components. When the cantilever scaffolding is set up with tie points in two steps and three spans according to specifications, the window sills are made of concrete, making temporary ties impossible and compromising safety.

To ensure the stability of the scaffolding during erection while ensuring time-saving, labor-saving, and safe operation for workers, targeted temporary support structures are needed.
