The invention belongs to the technical field of super high-rise building steel structure construction, and provides a mounting method for a concrete batter post, which comprises the following steps: S1, manufacturing the concrete batter post and a frame beam; s2, the concrete batter post and the frame beam are temporarily fixed; s3, a main hoisting chain block is arranged on the concrete inclined column; s4, a first balance chain block is arranged on the concrete inclined column, and a second balance chain block is arranged at the far end of the frame beam; s5, after the stable triangular body is lifted to the position 50 cm away from the ground through the main lifting chain block, the first balance chain block and the second balance chain block are adjusted; and S6, after the triangular body is stabilized in place, the triangular body is connected with the lower section component through temporary bolts, then connection of the frame beam and the adjacent steel column is completed, and finally all the chain blocks are removed. Compared with the prior art, the circular concrete batter post and the slope direction frame beam are pre-assembled on the ground to form the stable triangular body, and the four chain blocks are used for cooperatively controlling hoisting, so that the batter post and the associated beam are integrally lifted and accurately positioned.
