This paper thoroughly investigates the application and technical details of inverted formwork support systems in the construction of ultra-thick factory cast-in-place floor slabs. Targeting construction challenges posed by large equipment size, wide room spans, and heavy floor slab loads, the inverted formwork support system presents significant advantages due to its efficiency, flexibility, and stability. This system integrates a portal frame constructed from double-channel steel and steel beams mounted on wall corbels, forming an innovative support structure, further reinforced by the design of central columns. The paper elaborates on the process, including key steps such as positioning and alignment, installation of wall embedded parts, steel corbel and inverted formwork beam-column installation, high-strength tie rod installation, and the dismantling of the support frame, offering valuable insights and guidance for the relevant field.
