This paper introduces a new construction and installation technology of prefabricated concrete structure.Relying on the patented achievements of this technology,the prefabricated component units are divided on the premise of ensuring the integrity of the joint core area of concrete structure.This technology realizes the three-dimensional and layer-by-layer cyclic prefabrication through a unique supporting circulation system;and the preassembly of prefabricated components is achieved through the use of threaded heads and sleeves to pre-connect the steel bars.Thus,the prefabricated concrete structure is stronger than the cast-in-place structure,which can greatly improve the engineering quality of prefabricated concrete structure,and realize extremely convenient full assembly.This technology seeks to fundamentally solve the reliability and convenience problems of fabricated concrete structures,and appropriately improve the comprehensive economic benefits of prefabricated concrete structure.
