Cover plate conversion structure considering space-time effect

The invention discloses a cover plate conversion structure considering a space-time effect. The cover plate conversion structure is designed into a laminated slab structural form combined with a main beam, the upper surface of a layer of curved surface cover plate in the initial stage is corrugated, and the elevation is lower than that of a main beam surface; according to the use requirements of different time periods, the cover plate structure is divided into an initial condition and a later condition, and an initial upper complete large space is formed by combining a layer of curved surface cover plate and a temporary pavement in the initial stage; when the upper building is built in the later period, the cast-in-place laminated layer is used for replacing the temporary pavement to form a later conversion structure comprising the additionally-built upper structure. And during later construction, the cast-in-place laminated layer is engaged with the layer of curved surface cover plate in the initial stage th
