Abstract
This utility model discloses a stable connection structure for prefabricated building wall beams, including exposed reinforcing bars distributed on one side of the prefabricated beam and exposed reinforcing bars distributed on the top of the prefabricated wall. Each exposed reinforcing bar is welded with a circular block, and screw holes on several circular blocks are sequentially threaded to the same threaded steel rod. A concrete pouring space is formed between one side of the prefabricated beam and the top of the prefabricated wall. The difference in this utility model lies in the fact that the rationally distributed prefabricated holes ensure uniform stress on the U-shaped reinforcing bars, significantly improving the overall structural stability and deformation resistance. Simultaneously, the design of the circular blocks welded to each exposed reinforcing bar and the threaded connection between the screw holes and the threaded steel rod effectively avoids stress concentration problems that may occur with traditional welding methods, extending the service life of the structure.
