Each mounting hole is provided with an internal thread adapted to the external thread of the fastening bolt 122. The mounting holes and the fastening bolts 122 are arranged one-to-one. The end of the anchor away from the prefabricated component is used to be inserted into the groove 1211. The plurality of fastening bolts 122 are screwed into the plurality of mounting holes and abut against the outer peripheral wall of the anchor, so that the fixing disc 121 is connected to the anchor.

[0029] The fixed disc 121 has a threaded hole on one side, which extends along the center line of the fixed disc 121 and penetrates the fixed disc 121. One end of the grouting pipe 11 is connected to the side of the fixed disc 121 where the groove 1211 is provided.

[0030] Specifically, the threaded hole is located at the geometric center of the fixed disk 121, and the center line of the threaded hole is collinear with the center line of the fixed disk 121. The grouting pipe 11 is located at one end of the threaded hole and is correspondingly arranged with the threaded hole. The end of the connecting pipe 20 with external threads is screwed into the threaded hole, and the other end of the connecting pipe 20 extends to the outside along the center line of the threaded hole towards the end opposite to the grouting pipe 11.
