[0002] Prefabricated building construction technology has become a new trend in the development of the construction industry with its advantages of fast speed, high quality and environmental protection. In prefabricated concrete buildings, prefabricated external wall panels, composite beams and other components are widely used, among which the application of load-bearing components is relatively slow. The main reason is that most of the domestic understanding of the overall performance and seismic performance of prefabricated structures is still based on cast-in-place structures. Compared with traditional construction methods, prefabricated buildings are fast to build, less restricted by climatic conditions, save labor and improve building quality. However, during the process of inserting and guiding the reinforcement, the traditional prefabricated component hoisting needs to use a mirror to observe whether the reserved reinforcement is aligned with the hole, and secondary hole grouting is required in the later stage, which reduces the firmness and safety of the connection between the prefabricated wall body and the cast-in-place structure. Therefore, it is necessary to improve the existing structure in terms of how to achieve the rapid positioning and correction of prefabricated walls, beams and other components, and complete the grouting in one go during the installation of prefabricated walls.
