A second side outer wall pull rod 209 for dragging the side outer wall steel member to move is provided on one side of the side outer track 208. A walkway plate 210 is provided on the upper end of the H-shaped steel 201. When in use, the inner formwork system, the outer formwork system and the end formwork form a forming cavity 101, and then concrete is poured into the forming cavity 101 to form it. After the concrete solidifies, the end formwork is removed, the inner formwork system and the outer formwork system are demoulded, and the inner formwork system is moved out from the inside of the formed concrete through the walking system to complete the casting of the box-type prefabricated component.

[0041] In this embodiment, the outer formwork system includes side outer wall steel components, bottom wall steel components and rear wall steel components; the outer formwork system can be determined according to actual conditions and is not limited to only side outer wall steel components, bottom wall steel components and rear wall steel components;
