The front of the back connecting plate 5 is provided with a plug hole 6. The plug column 3 is slidably connected with the plug hole 6. The back connecting plate 5 is provided with a fixing channel 7. The fixing channel 7 is connected with the plug hole 6. The plug column 3 is provided with a through fixing hole 4. The fixing rod 8 is inserted into the fixing channel 7. When two prefabricated PK wall panel bodies 1 are connected, the front connecting plate 2 installed on one prefabricated PK wall panel body 1 is pressed against the back connecting plate 5 installed on the other prefabricated PK wall panel body 1. On, the column 3 is inserted into the socket 6, and after the fixing hole 4 opened on the column 3 is aligned with the fixing channel 7 opened on the back connecting plate 5, the handle 9 is held to insert the fixing rod 8 from the fixing channel 7, so that the fixing rod 8 enters from the fixing channel 7 and passes through the fixing hole 4 opened on the column 3, thereby completing the fixation of the front connecting plate 2 and the back connecting plate 5, so that the two combined prefabricated PK wall panel bodies 1 are spliced ​​and fixed. When a certain combined prefabricated PK wall panel body 1 needs to be replaced, it is only necessary to pull out the fixing rod 8 to replace the combined prefabricated PK wall panel body 1, avoiding the problem of removing adjacent prefabricated wall panels before replacing a single prefabricated wall panel, and there is no need for workers to use tools to rotate the threaded rod to assemble the prefabricated wall panels, which reduces the work intensity of workers and makes the replacement of prefabricated wall panels more convenient. Not opening limit holes on the prefabricated wall panels improves the external beauty of the wall panels.

[0026] Referring to Figures 1, 3 and 4, the channel of the fixing hole 4 is aligned with the fixing channel 7 up and down, which facilitates the fixing rod 8 to pass through the fixing hole 4 when inserted from the fixing channel 7. The fixing rod 8 is slidably connected to the fixing hole 4. A handle 9 is installed on the top of the fixing rod 8. Workers can hold the handle 9 to pick up and put down the fixing rod 8.

An insulation board 12 is arranged on the front side of the reinforcing steel bar 13, and a reinforcing board 11 is arranged on the front side of the insulation board 12. The reinforcing steel bar 13 running through the concrete slab 14 can increase the firmness of the prefabricated wall panel, and the insulation board 12 arranged on the front side of the reinforcing steel bar 13 enables the wall panel to have good thermal insulation effect. The filling material layer and the manufacturing process of the combined prefabricated PK wall panel involved in this application are both existing mature technologies. There are many combined prefabricated PK wall panels on the market. The protection content of this application does not involve improvements to the filling material layer and the manufacturing process of the combined prefabricated PK wall panel, so the filling material layer of the combined prefabricated PK wall panel is not described in detail here.

[0028] The implementation principle of a modular prefabricated PK wall panel in the embodiment of the present application is as follows: when two modular prefabricated PK wall panel bodies 1 are connected, the front connecting plate 2 installed on one modular prefabricated PK wall panel body 1 is pressed on the back connecting plate 5 installed on the other modular prefabricated PK wall panel body 1, so that the plug column 3 is inserted into the plug hole 6, and after the fixing hole 4 opened on the plug column 3 is aligned with the fixing channel 7 opened on the back connecting plate 5, the fixing rod 8 is inserted from the fixing channel 7 by holding the handle 9, so that the fixing rod 8 enters from the fixing channel 7 and passes through the fixing hole 4 opened on the plug column 3, Thereby, the front connecting plate 2 and the back connecting plate 5 are fixed, so that the two combined prefabricated PK wall panel bodies 1 are spliced ​​and fixed. When a certain combined prefabricated PK wall panel body 1 needs to be replaced, it is only necessary to pull out the fixing rod 8 to replace the combined prefabricated PK wall panel body 1, thereby avoiding the problem of removing adjacent prefabricated wall panels before replacing a single prefabricated wall panel, and there is no need for workers to use tools to rotate the threaded rods to assemble the prefabricated wall panels, which reduces the work intensity of workers and makes the replacement of prefabricated wall panels more convenient. The appearance of the wall panels is improved by not opening limit holes on the prefabricated wall panels.
