[0018] Combined with Figure 1 , Figure 2 , Figure 3A prefabricated building curtain wall comprises several groups of splicing units 1 and embedded parts 2. The splicing units 1 are fixedly connected to the outer wall of the building through the embedded parts 2. The splicing unit 1 comprises a frame 3, an outer frame 4, an inner frame 5, and a connecting part 6. The outer sides of adjacent frames 3 are sealed and connected by sealant. The front and rear sides of the frame 3 are provided with side grooves 7. The outer frame 4 and the inner frame 5 are respectively located in the side grooves 7 on the front and rear sides. Several positioning and mounting holes 8 are provided in the side grooves 7. The rear corners of the frame 3 are provided with first connecting grooves 9. The rear edge of the frame 3 is provided with several second connecting grooves 10. Several fixing blocks 11 are symmetrically provided on both sides of the rear of the frame 3. The front side of the embedded part 2 is provided with a mounting groove 12. The rear side of the embedded part 2 is provided with several galvanized embedded ribs 13. The adjacent fixing blocks 11 are located in the mounting grooves 12 and are fixedly connected to the embedded part 2 by bolts. The double-layer splicing unit 1 structure can improve the sound insulation and thermal insulation performance of the curtain wall.
