The invention relates to a high tower curved cross beam steel bar construction method. The high tower curved cross beam steel bar construction method comprises the steps that setting out is performedon a ground platform to determine side lines; web steel bars are installed; horizontal steel bars are installed; draw hook steel bars are installed to form skeleton structures; the skeleton structuresare segmented according to the lifting capacity, and if the lifting capacity of a lifting device is sufficient, performing no segmenting is allowed; stiffening profile steel is installed and liftinglugs are arranged at main lifting parts of the skeleton structures; the skeleton structures are separately lifted and transferred to design positions; and after the skeleton structures are lifted to the design positions, the skeleton structures are connected with pre-embedded steel bars in a tower through pre-embedded sleeves. According to the high tower curved cross beam steel bar construction method, integral platform prefabrication is adopted, a method of segmented lifting installation is used for construction, the characteristics such as high construction efficiency, good safety and high installation precision of the steel bars are achieved, the parallel operation of steel bar skeleton processing and bracket pre-pressing work is realized, and when the steel bar operation conditions areachieved after pre-pressing is completed, lifting is directly performed for splicing skeletons. According to the high tower curved cross beam steel bar construction method, the cost is saved, high-altitude operation is greatly reduced, edge operation is performed, the construction safety is greatly improved, and the installation precision of steel bar skeletons of an arc segment is improved.
