The bolt 4 is tightened by a bolt tightening device and the lower end of the bolt 4 is pressed against the top of the embedded part 5. The lower end of the bolt 4 presses against the embedded part 5 for two purposes: first, the vertical force of the external wall panel 1 is transmitted to the embedded part 5 through the tightening of the bolt 4 and the embedded part 5; second, the verticality and elevation of the external wall panel 1 are adjusted. After the lower end of the bolt 4 presses against the top of the embedded part 5, a first steel plate 6 is welded between the connection component 3 and the embedded part 5. Among them, the embedded part 5 is welded by a steel plate 51 and four embedded steel bars 52 located below the four corners of the steel plate 51. The top surface of the steel plate 51 is exposed to the structural corbel setting and is welded to the bottom of the first steel plate 6.

[0025] like Figure 2 and Figure 3 As shown, the connection assembly 3 includes a U-shaped frame consisting of two second steel plates 7 and an end plate 10, a third steel plate 8 fixed to the bottom of the U-shaped frame, and two anchor plates 9 fixed to the open ends of the U-shaped frame and respectively connected to the two second steel plates 7, wherein the anchor plates 9 are entirely embedded in the external wall panel 1, and a portion of the U-shaped frame near its open end is embedded in the external wall panel 1.

[0026] In addition, the first steel plate 6 is welded to the second steel plate 7 and the third steel plate 8 at the same time, and the top of the first steel plate 6 is connected to the side of the second steel plate 7. A nut 12 is welded to the bottom of the third steel plate 8, and the center of the nut 12 is a certain distance away from the end plate 10. A first hole 13 corresponding to the nut 12 is opened on the third steel plate 8. The diameter of the first hole 13 is 3-5mm larger than the diameter of the nut 12. The bolt 4 passes through the first hole 13 and is threadedly connected to the nut 12. The open end of the U-shaped frame is provided with steel bars 11. The steel bars 11 include horizontal steel bars passing through the two second steel plates 7 and vertical steel bars connected to the connection between the second steel plate 7 and the anchor plate 9. The steel bars 11 are entirely pre-buried in the external wall panel 1.

[0027] like Figure 4 As shown, the bolt tightening device consists of a hexagon socket 14, a steel pipe 15 and a cross bar 16. The hexagon socket 14 has a certain wall thickness, and the diameter of the hexagon socket 14 is consistent with the diameter of the top of the bolt 4. The hexagon socket 14 is sleeved on the top of the bolt 4, and the steel pipe 15 is welded to the top of the hexagon socket 14. The hexagon socket 14 is welded at the lower end, and the steel pipe 15 is welded at the upper end. The diameter of the steel pipe 15 is 5-10mm smaller than the outer diameter of the hexagon socket 14. The upper end of the steel pipe 15 is provided with a through hole for the cross bar 16 to pass through at a certain distance from the top thereof, and the through hole includes a second hole 17 and a third hole 18 that are perpendicular to each other and distributed up and down. According to actual conditions, the cross bar 16 can selectively pass through the second hole 17 or the third hole 18 to rotate the steel pipe 15 to achieve tightening of the bolt 4.
