Construction method of independent post-dismantling supporting type formwork quick dismantling system

The invention discloses a construction method of an independent post-dismantled supporting type formwork quick dismantling system, which comprises the following steps of: pouring concrete on the top surfaces of a supporting unit formwork and an independent post-dismantled batten of the independent post-dismantled supporting type formwork quick dismantling system, firstly dismantling a vertical rod B and the independent post-dismantled batten when a floor slab is formed after the strength of the concrete is met, and then dismantling the vertical rod B and the independent post-dismantled batten; and the supporting unit formwork, the vertical rod A, the bracket A, the batten A and the transverse pipe are not disassembled, so that the vertical rod A, the bracket A, the batten A and the transverse pipe still support the floor through the supporting unit formwork, and the floor is maintained to the design strength in the later period. After the strength of concrete poured on the supporting unit formworks and the to
