[0017] See also Figure 1-Figure 2 The utility model provides a technical solution: a grouting and plugging device for prefabricated columns of assembled buildings, comprising a shell 1 and a grouting nozzle 22: a slider 11 is slidably connected inside the shell 1, a grouting tube 12 is fixedly installed in the middle of the bottom side of the slider 11, a blocking block 13 is fixedly installed at the bottom end of the grouting tube 12, a sealing groove 14 is penetrated through the middle of the bottom side of the shell 1, the blocking block 13 is movably connected to the sealing groove 14, and the size of the blocking block 13 matches that of the sealing groove 14, the size of the grouting tube 12 matches that of the shell 1, a spring 15 is arranged on the bottom side of the slider 11, the spring 15 is sleeved on the outside of the grouting tube 12, and the size of the spring 15 matches that of the sealing groove 14.

[0018] In this technical solution, when the grouting nozzle 22 is removed to stop the grouting operation, the elastic force of the spring 15 can push the slider 11 to move upward in the shell 1, further pulling the grouting tube 12 and the blocking block 13 upward, and the blocking block 13 can seal the sealing groove 14. At the same time, the grouting groove 21 is retracted into the shell 1, thereby automatically sealing the grouting port of the prefabricated column.

The slot 2 is connected to the top of the grouting tube 12, and a grouting groove 21 is provided through the inner wall of the bottom end of the grouting tube 12. The grouting groove 21 is evenly distributed in a ring shape on the outside of the grouting tube 12.

[0020] In this technical solution, the slot 2 on the upper surface of the slider 11 facilitates the insertion of the slider 11 and the grouting nozzle 22. The grouting nozzle 22 can push the slider 11 downward, thereby pushing the grouting tube 12 downward, so that the grouting groove 21 at the bottom end of the grouting tube 12 moves out of the shell, and the mortar discharged from the grouting nozzle 22 is further discharged through the grouting groove 21 connected to the grouting tube 12.

[0021] In this embodiment, a fixing plate 3 is fixedly mounted on the outer side of the lower end of the housing 1 , and a fixing hole 31 is formed through the upper surface of the fixing plate 3 .

[0023] When using a prefabricated column grouting plugging device for an assembled building, the bottom end of the shell 1 is inserted into the grouting port of the prefabricated column, and the bolts are passed through the fixing holes 31 to fix the shell 1 to the prefabricated column (it should be noted that the size of the shell 1 matches the size of the grouting port of the prefabricated column). The slot 2 on the upper surface of the slider 11 facilitates the insertion of the slider 11 and the grouting nozzle 22. The grouting nozzle 22 can push the slider 11 downward, thereby pushing the grouting tube 12 downward, so that the grouting The grouting groove 21 at the bottom end of the tube 12 is moved out of the shell, and the mortar discharged from the grouting nozzle 22 is further discharged through the grouting groove 21 connected to the grouting tube 12. When the grouting nozzle 22 is removed to stop the grouting operation, the elastic force of the spring 15 can push the slider 11 to move upward in the shell 1, and further pull the grouting tube 12 and the blocking block 13 to move upward. The blocking block 13 can seal the sealing groove 14, and at the same time, the grouting groove 21 is retracted into the shell 1, thereby automatically sealing the grouting port of the prefabricated column.
