The intelligent jacking formwork system for high-rise buildings is a new type of construction platform for the construction of super high-rise core tubes. The application of large hydraulic cylinders as the climbing power has better adaptability to the structure with large core changes; System provides a larger, enclosed operating space for construction work, and the operation is safer. The support position is low, and the construction speed is faster. At present, this type of formwork system has achieved good results in a number of projects, and the comprehensive benefits are significant, and it will be widely used in the construction of super high-rise buildings in the future.

Intelligent hydraulic jacking formwork system: It is composed of six parts: steel truss platform, steel support column, double-acting hydraulic cylinder and its intelligent control hydraulic system, shaped large steel template and adjustable mobile pylon. The supporting hole buckle is reserved for the equipment on the inner wall of the vertical structure, the supporting box girder is supported at the reserved hole by the telescopic mechanism at both ends, the steel supporting column and the hydraulic cylinder are respectively fixed on the upper and lower two supporting beams, and the jacking and recovery action of the double-acting hydraulic cylinder are used to realize the self-climbing of the whole jacking mold system. The platform is lifted by the steel support column, and then the template and the pylon suspended under the steel truss platform are driven to jack up as a whole.

• The hydraulic cylinder is directly connected with the steel platform to lift the steel platform
• Cylinder passes through the support box girder, and the support box girder moves up along the cylinder block when jacking
• The steel platform truss is separated from the two layers to increase the stiffness of the truss and provide more sufficient platform use
• When the cylinder moves up, the hydraulic cylinder and the jacking box girder are stressed, and during the construction, the support box girder is stressed, and the hydraulic ram can release the pressure and can be replaced, overhauled or increased (it is difficult for other top molds to do this)
