Abstract
Combined with the actual situation of COMAC Jiangxi Production and Flight Test Center project,the application points and construction control of prestressed integral floor construction technolo-gy are analyzed.The large-area prestressed overall floor has high requirements for the flatness and crack control effect of the construction.The project combines the heavy and difficult points of the project,strict-ly controls the preparation work before the construction,the installation of bellows,the construction of concrete pouring,laser leveling,and the construction of each process of prestressed tension,lays pres-tressed tendons inside the concrete,and carries out prestressed tension.It effectively solves the shrinkage stress of concrete itself and resists the external load during the normal use of the floor.Through the appli-cation of prestress,the cutting joints of the floor and the ordinary steel mesh in the traditional floor can be eliminated,which effectively meets the requirements of the test flight center for the integrity and stability of the floor.关键词
