[0002] Prefabricated buildings are increasingly used in modern building structures due to their advantages of shortening construction period and saving energy, and prefabricated stairs are one of the prefabricated structures. Compared with cast-in-place stairs, prefabricated stairs usually have gaps between them for the convenience of hoisting construction, which affects the connection and penetration of the drip line at the bottom of the stair slab. The gaps in the prefabricated staircases are sealed after the construction is completed, often using a hanging mold, which not only increases the difficulty of construction, but also fails to meet the accuracy of grouting, and also affects the construction progress of the drip line at the bottom of the stair slab and the ground of the rest platform and the floor paint of the staircase. The side of the stairs has not been polished and there is a lot of garbage in the gaps, which is difficult to handle and affects the overall bonding strength. Summary of the invention
