Large-section bearing platform formwork mounting structure

The utility model belongs to the technical field of engineering construction, and particularly relates to a large-section bearing platform formwork installation structure which comprises a bearing platform bottom elevation and further comprises a plurality of rectangular box body structures which are placed in the horizontal direction and stacked in the vertical direction to form a bearing platform formwork system which is installed on the top face of the bearing platform bottom elevation. The rectangular box body structure is formed by connecting a plurality of ALC light partition boards end to end; according to the large-section bearing platform formwork installation structure, the ALC light partition boards serve as formworks, the board walls are transversely arranged and connected through the bolts, the boards form closed box bodies, and the upper box body and the lower box body are connected through the board wall male mortise and the board wall female mortise to form a formwork system.
