Application of Landing and Cantilevered Combined Formwork System at a High-level Layer by Layer Outer Cantilevered Structure Construction
The high-level layer by layer cantilevered concrete structure is unique in shape and complex in stress,there are many outstanding problems in the construction process,such as high technical difficulty,high safety risk,high cost of measures and long construction period.Taking the implementation of the unilateral high-level cantilevered concrete structure formwork system of the tower for Guanggu People's Hospital project as an example,the scheme is comprehensively compared and selected from the aspects of safety,economy and feasibility,and the landing and cantilevered combined formwork system is adopted.The load transfer path and various construction conditions of the structure are analyzed,and the fine design and checking calculation of the formwork system are carried out.Finally,the erection and demolition of the on-site formwork support system are guided strictly according to the design scheme.The practice shows that the proposed landing and cantilevered combined formwork system can safely,conveniently and efficiently complete the construction of high-level outer cantilevered concrete structure.
