This invention discloses a prefabricated staircase and its construction method, relating to the field of prefabricated building construction technology. By setting up the staircase body and two anchoring structures, under normal use, the anchoring structures provide sufficient vertical bearing capacity and horizontal shear resistance, ensuring the overall stability of the staircase. In the event of sudden disasters such as earthquakes, due to the presence of through-type anchor bodies within the anchor holes, when the stair slab participates in resisting lateral forces in the main structure, the shear force is mainly distributed to the load-bearing beam through the anchor bodies in the anchor hole area, rather than concentrated at the single lap interface between the stair slab and the load-bearing beam.
