A prefabricated component for an assembled building as claimed in any one of claims 1 to 6, characterized in that: The method for manufacturing the prefabricated components of the assembled building is as follows: First, seven rectangular non-disassembly formworks are made, the tail ends of the supporting steel bars are installed in the fixing plates of the steel bar positioning frames, and a number of the column steel bars are passed through the positioning grooves on the steel bar positioning frames to form column steel bar positioning frames; the fixing plates of a number of column steel bar positioning frames are fixed in four non-disassembly formworks by using internal connecting bolts to form a column cage formwork for filling and making concrete columns; a number of the beam steel bars are passed through the positioning grooves on the steel bar positioning frames to form a beam steel bar positioning frame; the fixing plates of a number of beam steel bar positioning frames are fixed in three non-disassembly formworks by using internal connecting bolts to form a beam cage formwork for filling and making concrete columns; Then, the column cage molds at the four main corners of the building are positioned, and a number of the column connecting members are fixed to the outer side of the end of the column cage mold by external connecting bolts; according to the size and installation position of the beam, the first suitable fastening hole on the column connecting member and the suitable position of the second fastening hole on the beam positioning member are found, and the fastening bolts are passed through the second fastening hole and the first fastening hole in sequence, and then the beam positioning member is positioned and connected to the suitable position on the column connecting member; the bottom edge of the end of the beam cage mold is placed in the U-shaped groove of the beam positioning member, and the positioning of the prefabricated components of the building is completed; Finally, concrete is poured into the cavities inside the column cage formwork and the beam cage formwork. The beam cage formwork and the column cage formwork are themselves made of special concrete. After the concrete solidifies, only the positioning connection components need to be removed without removing the non-removal formwork on the periphery.
