The present invention relates to a full-cavity concrete slab structure with high integrity and stability and excellent performance, a cavity structure, and a steel bar framework. The slab type concrete structure is internally provided with a slab type concrete structure unit. An external concrete shell of the slab type concrete structure unit is internally provided with oblique concrete partitions. Both ends of the external concrete shell are sealed. Two side panels of the external concrete shell form enclosed air cavities together with the corresponding oblique concrete partitions and the sealed ends at the both ends. The air cavities are arranged in continuous rows in a staggered manner. The steel bar framework is provided in the external concrete shell and the oblique concrete partitions. The present invention implements high integration of energy saving and environmental protection of structures and buildings. The slab structure not only satisfies the load-bearing resistance requirements of an original wall structure, but also makes the structure safer and more earthquake-resistant and disaster-proof, namely, the self-safety, self-energy saving, and self-environmental protection of the structure are fully achieved. The slab structure needs neither an exterior veneer and an interior veneer, nor materials such as middle embedded thermal-insulation and fireproof materials, and can be applied as a variety of concrete slab structures for buildings, and thus the product has a wide range of applications.
