The rapid surge of high-rise building challenge the technology of construction, and also the form of high-rise building structure becomes more and more larger and complicated. As the change of function of transfer floor, high-rise building transfer floor is an important measure for conveying the up-structure load. But with the increase of load the size of transfer floor is always great, so the new issues are bringing about. The research on construction technology for high-rise building transfer floor is greatly significant in projects domain. The dissertation mainly has a research on beam shape of concrete transfer floor. The load form of transfer floor is complicated and the stress-strain changes greatly, so the structure design could be divided into the calculations of rectangular sections in bending, incline plane in shearing, and shear wall structure. Because transfer floor is an important part in high-rise building, it needs special requests of design and structure.The beam shape of concrete transfer floor is completely studied. Firstly, for the system of moulding board and support frame in construction the side pressure and screws are analyzed. The material and structure form of support frame are discussed. The design of support frame uses the method of limited state, and also it analyses the integer stability, part stability, and single stability, and then proposes the load analysis of multi-level support frame. To the high-rise building's support frame, the dissertation proposes the approximate calculation based on half-rigidity steel frame. Secondly, Because of mass concrete structure for high-rise building transfer floor, the emphases is the control of cracks in construction. Based on that, the reason for producing cracks and the calculation must be analyzed. Especially the dissertation expounds the contract cracks in out restriction. In measures on the control of cracks the material, the rate of conjugate, the design of pour, and the structure form are all necessary. The calculation of temperature control for transfer floor concrete can adopt the methods of keeping temperature and sluicing water methods according to the cracks control for out restriction in order to informative construction. Finally, the dissertation takes ChongQing times square for example with the analysis of the support frame of transfer floor and temperature cracks' control.Especially the use of calculation software, SAP and ANSYS, get a good effect for the research on the support system of transfer floor.
