Mounting method of ALC light partition board

The invention relates to the technical field of building structures, in particular to a mounting method of an ALC light partition board. The ALC light partition board comprises at least two inner fixing columns mounted at the upper end and the lower end of the ALC light partition board correspondingly, springs connected with the inner fixing columns and limiting columns for fixing the inner fixing columns. Vertical blind holes for mounting the inner fixing columns and horizontal through holes communicating with the vertical blind holes are formed in the two ends of the ALC light partition board, the inner fixing columns and the springs are fixed in the vertical blind holes, the limiting columns are fixed in the horizontal through holes, and the limiting columns are used for fixing the inner fixing columns after the springs are compressed. The mounting method further comprises the following mounting steps that A, a partition wall steel clamp is fixed; b, the inner fixing columns are mounted; C, the ALC light p
