Tower Centering of High-Rise Connected Structure Based on Integral Lifting Construction Technology
In the construction technology of connection structures,integral lifting is an economical and efficient construction method widely used in engineering practice.However,in actual construction,the connection accuracy between the link and the tower is low.The key reason is that increasing the load will cause significant horizontal deformation of the tower.In order to solve such problems,the method of tower centering is proposed,and the implementation plan and design optimization analysis method are introduced in detail.The key idea of the tower centering method is that by applying horizontal loads to the tower,the additional horizontal deformation of the tower would be eliminated,and the tower would be close to its design state.After that,taking the Hangzhou Yunmen steel structure project as an example,two tower centering schemes are given in combination with the structural form and construction plan,and the feasibility and effectiveness of the tower centering are completely analyzed and the optimization method of the centering plan is given.Finally,the tower centering effect of the actual implementation is given.
