The utility model discloses a framework structure of a post-cast strip. The framework structure of the post-cast strip comprises a main building post-cast strip and a podium building post-cast strip. The post-cast strip utilizes a swelling waterproof strip which is arranged on the central position of a plate thickness of the post-cast strip. The swelling waterproof strip is fixed by tightly sticking on a side wall of the post-cast strip. A thin stone concrete strip is prefabricated on two sides of the post-cast strip. A brake raft of the main building post-cast strip utilizes a wood keel and a horizontal steel tube to be reinforced and supported. A brake raft of the podium building post-cast strip utilizes steel wire meshes, wherein the keel is made of a steel bar. The framework structure of the post-cast strip has the advantages of being simple in constructing operation, better in stiffness and strength, strong in overall stability, simple in installation and strengthening, smooth in the surface of poured concrete products, better in apparent quality, reliable and safe, and considerable in economic benefits and production efficiency. The framework structure of the post-cast strip saves manpower and material resources, lowers engineering cost, and greatly improves and guarantees safe performance.
