Disassembly-free formwork for secondary structure ring beam

The utility model relates to the field of building construction, in particular to a non-dismantling formwork for a secondary structure ring beam, which comprises a prefabricated formwork body, the thickness of the formwork body is consistent with that of a wall body, a mounting cavity for mounting reinforcing steel bars is arranged in the formwork body, and the reinforcing steel bars comprise a plurality of annular ribs and a plurality of vertical ribs. The vertical ribs are fixedly connected with the annular ribs, the plane where the annular ribs are located is perpendicular to the axis of the vertical ribs, and the annular ribs and the mounting cavity are coaxially arranged. According to the scheme, the prefabricated formwork body has the strength for supporting stacking of the upper-layer wall body, when concrete in the mounting cavity is not solidified, stacking of the upper-layer wall body can be conducted at the same time, the stacking time of the upper-layer wall body is not affected by the duration ne
