To adjust the construction industry structure,improve the construction quality,save energy,protect environment and reduce the project cost,it is very necessary to develop the prefabricated building,particularly the assembly reinforced concrete frame structure.Firstly,the paper introduced the basic reason of insufficient development of the prefabricated RC frame structure.Secondly,several innovative technology was proposed in this paper,including the PC member construction,the beam-column joints,the overlap method,the two-way mechanical mechanism of the hollow floor,the continuous slab belt,the cracks,the structural integrity,the fire safety,flame or smoke control,etc.Finally,according to the above innovative technology,the corresponding tests and actual engineering were conducted.Results show that the above innovative technology can be used in the actual engineering,which is beneficial to the development of the prefabricated RC frame structure and hollow floor.
