B-1 and B-2 buildings in Guangzhou Tianjian Garden are two-tower connection structure,which include steel truss connection structure and air swimming structure.According to structural characteristics and condition on site,integral hydraulic synchronous lifting technology is adopted,and it chooses frame column of main building as lifting points.After location of steel truss connection structure,in order to avoid influence on steel strand,upper lifting point is designed as double bracket type,on which short sliding beam is set.The design,principle and construction technology of lifting platform,stent and anchorage point are introduced in detail.And the lifting stent is checked,the results show that the strength,integral and local stability of components can meet requirements.
