Movable assembly type formwork mounting and demounting operation system and construction method thereof

The invention discloses a movable assembly type formwork mounting and demounting operation system and a construction method thereof. The movable assembly type formwork mounting and demounting operation system comprises a movable supporting frame and a cantilever beam fixed to the top of the movable supporting frame. The two sides of the cantilever beam are provided with chain blocks through flyingrings, and the chain blocks are provided with steel wire ropes for connecting and hoisting formworks. The bottom of the movable supporting frame is provided with fixing supports which can fix the current position of the movable supporting frame. The construction method comprises the steps that firstly, a working face is cleaned; secondly, installation position lines of the formworks are measuredand laid; thirdly, the movable supporting frame is arranged on a pipe ditch foundation, the fixing supports are opened to ensure that the movable supporting frame is stable, the chain blocks are hungon the flying rings, and th
