Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Reference Figure 1 、 Figure 2 and Figure 6 , the utility model provides an embodiment: a prefabricated wall joint waterproof structure, comprising a plurality of prefabricated walls 1, a plurality of prefabricated walls 1 are installed with a connecting piece 2 on an adjacent side, the connecting piece 2 is used to connect the prefabricated walls 1, a button 3 is installed on the front side of the connecting piece 2, and an extrusion piece 4 is fixedly connected to the rear side of the button 3, two pressure pieces 5 are arranged inside the connecting piece 2, and the two pressure pieces 5 are fixedly connected to a connecting column 6 on the opposite side, and the interiors of the two connecting columns 6 are slidably connected to a sliding rod 7, and the two sliding rods 7 both pass through the pressure piece 5, and when the extrusion piece 4 moves downward to a preset position, the sliding rod 7 will move to both sides, and the sliding rod 7 can be installed inside the connecting piece 2. Two cylindrical shells 8 are installed, and the tops of the two cylindrical shells 8 slide Two upper telescopic members 9 are connected, and sliding holes 14 are provided on the adjacent sides of the two cylindrical shells 8. Two telescopic holes 15 are provided on the top of the connecting member 2. The bottoms of the two cylindrical shells 8 are slidably connected with lower telescopic members 10. Springs 11 are installed on the adjacent sides of the two upper telescopic members 9 and the lower telescopic member 10. The springs 11 are compressed during installation. Expansion boxes 12 are provided inside the two springs 11. Sealing ports 13 are provided on the adjacent sides of the two expansion boxes 12. Expansion agents are provided inside the two expansion boxes 12. The expansion agents react when the sealing ports are broken. A fastening mechanism 16 is provided on the right side of the connecting member 2. The fastening mechanism 16 is used to fasten the connected sealing strips to enhance the waterproof ability of the joints of the prefabricated wall 1.

[0041] Specifically, when installing the connector 2 of the prefabricated wall 1, first install the two prefabricated walls 1 vertically, then thread the connecting bolt 22 into the prefabricated wall 1 to ensure the stability of the connection, and then slide the connector 2 onto the connecting bolt 22. At this time, slide the two prefabricated walls 1 into the connecting bolt 22. After completing these steps, press the button 3 inward. The inward movement of the button 3 will drive the extrusion member 4 to move inward. During the inward movement of the extrusion member 4, the pressure-bearing member 5 will move to both sides.
