The project applies the steel column tube frame alternate supporting integral steel platform formwork system to the construction of the core tube shear wall structure, The large volume super high inclined wall structure poses a new challenge to the overall steel platform equipment and construction technology.
Based on the BIM model of the equipment structure, a large number of dynamic construction simulations are carried out.
The project gives full play to the core technical capabilities in the field of super high-rise construction equipment system and safety protection technology, and makes progress in the field of complex super tall structure construction with integrated application of information technology.
Integrated steel platform equipment, structure, finite element model, equipment collision detection, edge hazard source modeling, Part4, real-time pressure monitoring technology project department of inclined wall steel large formwork, carried out in-depth cooperation with the Group Research Institute, relying on the group’s key topic “Research on intelligent integrated steel platform formwork and support device technology suitable for core tube inclined wall”, and aimed at the construction problems of inclined wall structure concrete formwork, The research group developed the real-time monitoring technology for the internal pressure of the inclined wall steel large formwork, which realized the real-time monitoring, evaluation and early warning of the lateral pressure of the cast-in-place concrete formwork, reduced the construction risk of the inclined concrete formwork, and provided a strong support for the assurance of the molding quality of the inclined wall concrete structure..

The completion of the project will help Zhangjiang Science City to become a national science center, a source of emerging economic growth in the Yangtze River Delta, and a Shanghai science and technology innovation center.
It is a symbol and symbol of Zhangjiang facing the world and welcoming global entrepreneurs to build a world-class science city in Zhangjiang.
Zhangjiang “Science Gate” East Tower Project is located in the core area of Shanghai Zhangjiang Science City and Zhangjiang City Sub center, with a total floor area of about 320000 square meters, including a 59 storey, 320 meter high office tower, a 25 storey, 100 meter high hotel tower, a 4-storey commercial building and a 3-storey cultural center, and a 4-storey basement as a whole.
Profile steel support is used as the supporting system of inclined shear wall steel formwork, The internal cantilevered bent is set as the formwork support system of the inclined coupling beam, which ensures the stability of the formwork system under the pouring and tamping conditions of the inclined wall concrete, effectively controls the deformation of the inclined wall structure, and fully guarantees the construction quality.
During the construction process, the structural deformation adjustment of the external hanging scaffold, internal tube frame and bottom beam of the integral steel platform is accurately controlled, and the lifting column The accurate displacement scheme of the steel corbel layer by layer ensures the stable and safe climbing of the overall steel platform and provides a solid foundation for the construction of the inclined wall structure.
Part 1 Deformation adjustment technology of integral steel platform for inclined wall construction During the layer by layer construction of the core tube inclined wall structure, the integral steel platform equipment structure adapts to the development of the inclined wall and deforms layer by layer.
The Project Department has carried out technical research on the main construction difficulties, developed a more detailed construction plan by using information technology, and carried out comprehensive technical support and process control during the construction process.
Based on BIM construction deduction, a form of steel formwork with strip drawing and formwork matching is proposed to adapt to the deformation conditions of inclined wall.
On October 24, the core tube structure of the office tower of Plot 58-01 (East Tower of Science Gate) in Zhangjiang Central District was successfully capped.
It is a super high-rise project that combines various high-end business forms such as office, hotel, commerce, and culture.
With the help of several safety protection measures, the safe and stable construction of inclined wall structure is ensured.
