Ltd.Shenzhen Guangdong 518040 China) Abstract: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 ponents can meet requirements. Key words:connection structure;steel truss;hydraulic synchron...
