Large-span step-shaped arc-shaped beam construction method based on adjustable formwork

The invention relates to the field of building construction, in particular to a large-span step-shaped arc-shaped beam construction method based on adjustable formworks, and solves the problems that the size and radian of the formworks are fixed, the adaptability and fault tolerance of the formworks to other parts in a project are small, the stability and sealing performance of connection between the formworks are affected, and then the project quality is affected. The first beam plates and the third beam plates are arranged in the vertical direction, the second beam plates and the fourth beam plates are arranged in the horizontal direction, every two adjacent first beam plates are hinged, every two adjacent third beam plates are hinged, the second beam plates are hinged to the upper edges of the corresponding first beam plates, and the fourth beam plates are hinged to the upper edges of the corresponding second beam plates. The fourth beam plates are hinged to the lower edges of the corresponding third beam
