[0029] A rubber sleeve 602 is fixedly sleeved on the outer wall of the plug post 6 , and the rubber sleeve 602 is cooperatively connected to the second mounting hole 5 .

[0030] The rubber sleeve 602 is used. After the plug post 6 is inserted, the rubber sleeve 602 is in close contact with the hole wall of the second mounting hole 5 through elastic deformation.

[0031] In a specific implementation, the positioning plug-in includes an insertion rod 8 and a coil spring 12; a positioning hole 10 is provided on the outer wall of the insertion column 6, and a groove 11 is provided on the hole wall of the conical hole 601, and the groove 11 is connected with the positioning hole 10; the insertion rod 8 is connected with the positioning hole 10 with a clearance fit, and the insertion rod 8 is adapted to the insertion hole 14. The coil spring 12 is sleeved onto the insertion rod 8, and the coil spring 12 is installed in the groove 11. One end of the coil spring 12 is fixedly connected to the rod surface of the insertion rod 8, and the other end of the coil spring 12 is fixedly connected to the groove wall of the groove 11. The insertion rod 8 passes through the groove 11, and a slope 801 is provided at one end of the insertion rod 8. The insertion column 6 is a conical structure, and the slope 801 is in contact with the conical surface of the insertion column 6.

[0032] After the plug 7 is inserted into the tapered hole 601, the insertion rod 8 can be inserted into the insertion hole 14 by squeezing for positioning; and through the design of the coil spring 12, when the plug 7 is not inserted, the elastic action of the coil spring 12 can keep the insertion rod 8 in a contracted state, which will not affect the insertion of the plug 6 into the first mounting hole 3 and the second mounting hole 5.

[0033] Furthermore, a convex plate is provided at one end of the plug post 6 outside the slot 101, and a embedding groove 603 is formed on the convex plate, and the embedding groove 603 is connected to the tapered hole 601. A cover 13 is provided inside the embedding groove 603, and the cover 13 is welded to the embedding groove 603.

[0034] The sealing disk fixed by welding can block the plug 7, thereby improving the positioning effect of the plug 7.

[0039] Working principle: In the specific implementation, when the entire connection structure of the building prefabricated component is in use, during the connection process of two building prefabricated component bodies 1, the socket 4 of one building prefabricated component body 1 is inserted into the slot 101 of the other building prefabricated component body 1 for plug-in installation. After the plug-in installation, the first installation hole 3 is aligned with the second installation hole 5. After alignment, the plug column 6 is inserted from the first installation hole 3 and the second installation hole 5 until the stopper 9 is in place and contacts the outer wall of the building prefabricated component body 1. At this time, the plug column 6 is aligned with the plug hole 14;

[0040] Then, the plug 7 is inserted into the tapered hole 601. Figure 2 Transform to Figure 4 state, and during the insertion process, the conical surface of the plug 7 squeezes the inclined surface 801 of the plug 6, so that the plug 6 moves, and the plug 6 is inserted into the hole 14 through the guidance of the positioning hole 10, and the coil spring 12 is compressed to produce compression deformation, thereby completing the positioning after installation; after insertion, the friction force between the plug 7 and the conical hole 601 is frictionally positioned, and then the cover 13 is installed on the embedded groove 603, and then the cover 13 and the plug 6 are welded by a welding gun, which provides a barrier for the plug 7 again, ensures the positioning effect of the plug 7, and then ensures that the plug 6 is inserted in the hole 14. Under vibration conditions, the connection cannot be loosened, thereby improving the stability of the connection.
