Application of splited whole grout sleeve connection in beam-column joints of precast frame structure
Precast frame structure is recognized as one of the most suitable structural forms for assembly in the world,but there are many difficulties in the traditional beam reinforcement connection method of beam-column joints,which limits the development of precast frame structure in China to a certain extent.A new type of splited whole grout sleeve suitable for butt joint of reinforcement in small space beam-column joints was introduced and applied in the project of precast frame structure.The key points of joint deepening design,component production and installation construction in the application of splited whole grout sleeve connection were summarized.The project implementation results show that the splited whole grout sleeve can effectively shorten the required installation and operation space,realize the standardized design of components,facilitate the production of components and speed up the on-site installation.
