| Abstract: | The first hangar roof of the new hangar projects of Shenyang Aircraft Maintenance Base consists of a three-layer diagonal square pyramid grid and steel trusses,whose span is long with complicated joints and large amount of steel is needed.Hence it is very difficult to install insitu.To ensure the quality of the project,after finishing the ground assembling the overall lifting was used.It was expounded the optimal arrangement to enhance the lifting point,structural reinforcement,concrete columns checking,improvement on synchronous control technology,quality control and quality monitoring technology etc.Finally the expected architectural goals were got. |
