Turnover plate formwork supporting system

The invention relates to a turnover plate formwork supporting system which is formed by mutually connecting a plurality of supporting units, each supporting unit comprises a plurality of support corner fittings, the support corner fittings are connected through support telescopic shafts to form a supporting platform, and a plurality of supporting telescopic shafts used for supporting formworks are arranged in the supporting platform. Jacks used for adjusting the vertical height of the supporting platforms are arranged below the supporting platforms, the adjacent supporting platforms are detachably connected through the jacks, and the top ends of the jacks are flush with the tops of the support corner fittings so as to play a role in supporting a poured structure. According to the turnover plate formwork supporting system, adjustment in the X direction and the Y direction can be achieved, the turnover plate formwork supporting system adapts to formworks of different sizes, after pouring is completed, the suppo
