[0002] With the rise of prefabricated buildings, prefabricated bay windows can be produced in the factory in advance and then transported to the construction site for installation. At present, the structure of prefabricated bay windows and their connection relationship with the connecting body have the following main shortcomings: (1) As a special-shaped component, the fully prefabricated bay window is prefabricated as a whole. In the production process, there are disadvantages such as cumbersome three-dimensional template production process, low production efficiency and high production cost. In addition, during the demoulding, lifting, transportation and installation of the component, it is easy to crack, fall off and collide. (2) Only one bay window connection steel bar is extended into the cast-in-place beam and wall. The connection stability is weak during construction, which poses a safety hazard. If a building requires a double bay window prefabricated component, there are still two components interrupting the structural beam, which is not conducive to the structural stress performance.

[0003] In summary, there is an urgent need to provide a prefabricated wall node structure using a composite bay window panel to meet the building function requirements, have good overall structural stress performance, and at the same time meet the prefabrication rate requirements, with convenient construction and good economy.

[0009] According to an embodiment of the present application, steel bars are reserved at the top of the prefabricated exterior wall and connected to the reserved holes of the upper prefabricated exterior wall by vertical positioning grouting.
