The invention discloses an integral hoisting construction method for an upper tower column framework. The method comprises the following steps. The method comprises the following steps: 1, designing an upper tower stiff skeleton; step 2, calculating the load of the stiff skeleton of the upper tower column; and step 3, integrally hoisting the stiff skeleton and the prestressed steel beam of the upper tower column. In order to guarantee accurate positioning of the high-strength steel wire bundles and guarantee safety of construction on the tower, the stiff framework and the high-strength steel wire bundles are assembled and integrally hoisted on the ground. The method also has the following beneficial effects. (1) under the condition that the whole-section framework and the segmented framework are hoisted at multiple hoisting points, the strength and the rigidity of the stiff framework meet the requirements; (2) a scissor inclined strut is installed according to a scheme drawing; (3) stiff skeleton nodes are co
