[0002] In the traditional construction field, the construction of floor structures has always been one of the key links. In order to ensure the stability and safety during concrete pouring or prefabricated component installation, in traditional construction, floor structures usually rely on a large number of temporary support systems to ensure stability and safety during the pouring or installation process.

[0003] Traditional construction methods not only increase construction difficulty and cost, but also extend the construction period. The currently used floor support-free structure usually has a low load-bearing capacity of the floor slab, and the installation process is cumbersome and time-consuming, further increasing construction costs and time costs.

[0004] To this end, the present application provides a residential building structure with a floor support-free structure. Utility Model Content
