The inner formwork comprises a vertical part and a horizontal part connected to each other, and the horizontal part is connected to the upper end of the vertical part. The upper side is connected to the horizontal part by bolts.

[0004] Preferably, the horizontal part has a mounting tab on the upper end, and the mounting tab has a thread on the inner side that can cooperate with the bolt. The upper side has a bolt hole coaxial with the mounting tab.

[0005] Preferably, it comprises a movable buckle and a fixed screw, the fixed screw is detachably connected to the upper side, and one end of the movable buckle is tied to the exposed steel bar at the top of the prefabricated beam, and the other end is connected to the fixed screw.

[0006] Preferably, the fixed screw has a bidirectional through hole, and one end of the movable buckle passes through the through hole and is tied to the fixed screw.
