Formwork hanging structure system for nuclear power reactor cabin top plate and construction method of formwork hanging structure system

The invention relates to a suspended formwork structure system for a nuclear power reactor cabin top plate and a construction method of the suspended formwork structure system, relates to the technical field of nuclear power engineering structure construction, and aims to solve the problem that no space is provided for erecting a formwork supporting system on the ground in a nuclear power reactor cabin. The upper partition suspended beam system comprises a plurality of first supporting rods erected on the top of the side wall of the nuclear power reactor cabin and a plurality of second supporting rods erected on the first supporting rods. The middle separating and hanging beam system comprises a supporting platform, a plurality of hanging rods are installed between the supporting platform and the second supporting rods, a formwork is arranged on the supporting platform, and a pouring cavity is defined by the formwork and the side wall of the nuclear power reactor cabin; and the bottom operation protection sys
