Post-cast strip beam plate formwork supporting structure

The utility model relates to a building formwork supporting structure, in particular to a post-cast strip beam formwork supporting structure which solves the problem that concrete can be poured into a post-cast strip easily when the post-cast strip is constructed. The post-cast strip beam formwork supporting structure comprises integrated project scaffolds on the two sides, a post-cast strip supporting scaffold, a slab form and an independent formwork at the position of the post-cast strip, wherein the post-cast strip supporting scaffold is connected with the integrated project scaffolds on the two sides through short steel pipes, the slab form is arranged above the integrated project scaffolds, the post-cast strip supporting scaffold is arranged below the independent formwork at the position of the post-cast strip, a cleaning hole is formed between the independent formwork at the position of the post-cast strip and the slab form, and movable formworks are arranged on the two sides of the independent formwork
