[0002] In existing construction methods, the edge members of shear walls are mostly cast-in-place, with complex connection details. The connection between cast-in-place edge members and precast components requires meticulous design and construction. Due to the high precision requirements, the installation accuracy of precast components and the construction quality of the cast-in-place portion directly affect the overall structural performance, thus requiring strict control.

However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0029] Example 1, combined with Figure 1 , Figure 2 and Figures 7-9 This embodiment describes a prefabricated edge component assembly system, which includes a prefabricated edge component 1 and a composite prefabricated component. The prefabricated edge component 1 is machined with connecting rib holes 6, and connecting ribs 7 are connected to the prefabricated edge component 1 through the connecting rib holes 6. The prefabricated edge component 1 is connected to the composite prefabricated component through the connecting ribs 7. The prefabricated edge component 1 is also machined with grouting holes 8 and venting holes 9.
[0030] The composite precast component is a double-sided composite connecting beam 2, which includes an inner beam surface 12, an outer beam surface 13, and beam stirrups 14. The inner beam surface 12 and the outer beam surface 13 are connected by beam stirrups 14. The double-sided composite connecting beam 2 and the prefabricated edge component 1 are prefabricated in the factory and transported to the construction site. The connecting bar 7 is inserted into the connecting bar hole 6 of the prefabricated edge component 1. The other end of the connecting bar 7 is arranged in the gap between the inner beam surface 12 and the outer beam surface 13. Concrete is poured into the gap between the inner beam surface 12 and the outer beam surface 13. After the concrete solidifies, the double-sided composite connecting beam 2 and the connecting bar 7 of the prefabricated edge component 1 are connected. Grouting material is injected into the grouting hole 8 of the prefabricated edge component 1. When the grouting material is discharged from the vent hole 9, it proves that the prefabricated edge component 1 is filled with grouting material, and the on-site construction of the prefabricated edge component 1 and the double-sided composite connecting beam 2 is completed.
[0031] The bottom of the double-sided composite beam 2 is connected to a non-load-bearing wall 10. The non-load-bearing wall 10 and the double-sided composite beam 2 are prefabricated as a single unit in the factory. Openings 11 are machined into the non-load-bearing wall 10, which can be used to machine components such as windows, ventilation holes, and doors. Figure 9 As shown, the outer beam surface 13 of the double-sided composite beam 2 is higher than the inner beam surface 12. One end of the beam stirrup 14 is connected to the inner side of the outer beam surface 13, and the other end is connected to the top of the inner beam surface 12. At the same time, a staggered step is processed on the upper end surface of the prefabricated edge component 1. This setting reduces construction errors during the installation process on the construction site, improves installation accuracy, eliminates the need for the formwork process at the floor slab position, saves costs, and increases construction speed.
[0032] Example 2, combined with Figure 1 and Figure 3 This embodiment differs from Embodiment 1 in that the composite prefabricated component is a single-sided composite connecting beam 3. The single-sided composite connecting beam 3 includes an outer beam surface 13 and beam stirrups 14. The beam stirrups 14 are installed on the outer beam surface 13. The connecting bars 7 on the prefabricated edge component 1 pass through the beam stirrups 14 and are solidified by grouting and concrete pouring, thereby connecting and fixing the single-sided composite connecting beam 3 to the prefabricated edge component 1.
[0033] Example 3, combined with Figure 1 , Figure 4 and Figure 5 This embodiment differs from the previous embodiments in that the precast composite component is a double-sided composite shear wall 4. The double-sided composite shear wall 4 includes an inner wall surface 15, an outer wall surface 16, truss reinforcement 17, and shear wall reinforcement 18. The inner wall surface 15 and the outer wall surface 16 are connected by multiple truss reinforcement 17. Multiple shear wall reinforcement 18 are mirror-arranged on the outer side of the inner wall surface 15 and the inner side of the outer wall surface 16, respectively. The truss reinforcement 17 and the shear wall reinforcement 18 are connected in cooperation. Multiple distribution reinforcement 19 are evenly distributed on the side wall of the prefabricated edge component 1. After the distribution reinforcement 19 on the prefabricated edge component 1 passes through the shear wall reinforcement 18, concrete is poured into the gap between the inner wall surface 15 and the outer wall surface 16. After the concrete solidifies, the prefabricated edge component 1 is connected and fixed to the double-sided composite shear wall 4.
[0034] Example 4, combined with Figure 1 , Figure 6 This embodiment differs from the previous embodiments in that the precast composite component is a single-sided composite shear wall 5. The single-sided composite shear wall 5 includes an outer wall surface 16, truss reinforcement 17, and shear wall reinforcement 18. Multiple truss reinforcement 17 and shear wall reinforcement 18 are evenly distributed on the inner side of the outer wall surface 16. The truss reinforcement 17 and shear wall reinforcement 18 are connected together. Multiple distribution reinforcement 19 are evenly distributed on the side wall of the prefabricated edge component 1. After the distribution reinforcement 19 on the prefabricated edge component 1 is connected to the shear wall reinforcement 18, it is fixed by concrete curing, so that the prefabricated edge component 1 is connected and fixed to the single-sided composite shear wall 5.
[0035] This embodiment is merely an exemplary description of the present utility model and does not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of the present utility model, they are all within the scope of protection of the present utility model.
