[0048] Example 1

[0049] Combination Figures 1 to 4The present embodiment provides a device for repairing holes in concrete after core drilling, comprising: a support member 10, with mounting holes 11 provided at both ends in the length direction, and a socket slot 12 extending along the length direction of the support member 10 provided at the upper end; a casting head 20, with a socket plug 21 adapted to the socket slot 12 provided at the lower end, and a casting cavity 22 provided at the upper end, and template slots 23 and vibration holes 24 are provided on both side walls parallel to the length direction of the socket plug 21; wherein the template slot 23 extends downward from the upper end of the casting head 20, and the template slot 23 and the vibration hole 24 are both connected to the casting cavity 22.

[0050] Combination Figure 4 One side of the socket slot 12 in the length direction penetrates the side wall of the support member 10 so that the sealing template inserted in the template slot 23 can directly fit with the side wall of the concrete member 40.

[0051] Combination Figure 5 The cross section of the socket slot 12 is rectangular, and the cross section of the corresponding socket plug 21 is also rectangular, so as to reduce the processing difficulty of the socket slot and ensure the stability of the sealing template and the casting head 20 when they are inserted into the socket slot 12.

[0052] Typically, mounting ears 13 are provided at both ends of the support member 10 in the length direction, and the mounting holes 11 are provided on the mounting ears 13 , which facilitates the processing of the mounting holes 11 on the one hand, and can reduce the material and weight of the support member 10 on the other hand.

[0053] It should be understood that the casting groove can be a rectangular groove or a groove with one side inclined. In the present embodiment, the bottom of the casting cavity 22 is hemispherical, which ensures that the concrete mortar can be injected into the hole while reducing the amount of concrete mortar remaining in the casting cavity 22, thereby reducing the waste of concrete mortar.

[0054] As for the vibration holes 24, in this example, a plurality of the vibration holes 24 are provided, and the plurality of vibration holes 24 are evenly distributed around a preset circle, so as to ensure the uniformity of vibration and compact the concrete mortar.
