Abstract：
The external wall of Wedge Building project in Changzhou is a super-large cantilever irregular wave-shaped circular structure with cantilever balconies of different lengths. The engineering construction is successfully completed by using many techniques, such as formwork fabrication technique supported by construction line drawing and CAD drawing, construction technique of highly-supported formwork of circular balcony beam slab, external wall large cantilever scaffold technique and construction lifter wall attaching technique, etc., providing experiences and references for similar projects.
