Cast-in-situ stairs bottom formwork
The invention relates to a cast-in-situ stairs bottom formwork which comprises a first formwork, a third formwork and a second formwork. The first formwork can be fixedly mounted at the bottom of a pouring position of a concrete structure on the lower portion of stairs, the third formwork can be fixedly mounted at the bottom of a pouring position of a concrete structure on the upper portion, and the second formwork can be fixedly mounted at the bottom of a position corresponding to a construction joint between concrete on the lower portion and concrete on the upper portion. The cast-in-situ stairs bottom formwork is characterized in that a round hole is formed in the second formwork, a round plate is arranged in the round hole, and one end of the round plate is connected with the second formwork through a hinge while the other end of the same is connected with the second formwork through an inserting pin. By the cast-in-situ stairs bottom formwork, concrete residue can be cleaned at one time, so that construction time is reduced, and concrete pouring quality of the stairs is improved.
