The utility model discloses a device for separating concrete with different strengths at a column-beam-slab node, which comprises a flexible fixing piece and a steel wire mesh fixing piece arranged on the flexible fixing piece, the flexible fixing piece is used for being fixed at the position of a reinforcing steel bar before pouring, and the steel wire mesh fixing piece is used for fixing a steel wire mesh. The flexible fixing pieces are arranged at the positions of the steel bars before pouring and are fixedly connected with the corresponding steel bars, then the steel wire mesh fixing pieces arranged on the flexible fixing pieces are used for fixing the steel wire mesh, concrete of different strengths is separated, installation is easy, after completion, the device can be rapidly disassembled, repeated use can be achieved, and the construction cost is reduced. The problems that the dense-mesh steel wire mesh separation installation process at the column-beam-plate joint is complex and tedious and cannot be
