[0002] Precast concrete walls form assembled concrete structures through reliable connection structures. This structure has a short manufacturing period, saves resources and labor costs, and has broad development prospects. The existing connection method between precast concrete walls is usually to prefabricate the extension connectors in the wall, connect the two walls with the connectors, and then support the formwork and pour concrete to fix them. This connection method requires embedded connectors, so the structure is relatively complex and the construction is cumbersome. It also has disadvantages such as uneven surface of the vertical joint section. Summary of the invention
