The mother mold 01 is a plate-shaped body, and a through hole 11 is provided on the mother mold 01. The through hole 11 forms a first grouting port, and the first grouting port is used to grout into the template of the secondary structure to be poured. The mother mold 01 is used to be connected to the template wall of the secondary structure to be poured. The mother mold 01 is vertically arranged, and the mold bucket 02 is detachably connected to the mother mold 01. The mold bucket 02 is provided with a feeding port on the top and a discharge port on the bottom. A second grouting port is provided on the side, the feeding port is used to add concrete to the die bucket 02, and the discharge port is used to remove excess concrete in the die bucket 02. The second grouting port corresponds to the position of the first grouting port, and is used to pour the concrete in the die bucket 02 into the template of the secondary structure through the first grouting port. In this embodiment, the secondary structure is a structural column. The die bucket discharge port opening and closing component 05 is connected to the mother mold 01, and the die bucket discharge port opening and closing component 05 is used to open or close the discharge port. The sealing plate 03 is connected to the mother mold 01, and the sealing plate 03 is used to seal on the feeding port. When the secondary structure grouting device of the utility model is used, the mother mold 01 is fixed on the template wall of the secondary structure to be poured, and the concrete is poured into the template of the secondary structure through the mold bucket 02, the second grouting port, and the first grouting port until the horizontal line of the concrete reaches the highest bearing position of the mold bucket 02, and the sealing plate 03 is closed downward, and the sealing plate 03 drives a small part of the concrete in the mold bucket 02 to be squeezed into the template of the secondary structure, so that the top of the template cavity of the secondary structure is completely in contact with the bottom surface of the load-bearing beam, and then the mold bucket discharge port opening and closing component 05 is opened to allow the excess concrete in the mold bucket 02 to flow out, and after waiting for the concrete in the structure to solidify, the mother mold 01 is disassembled together with the sealing plate 03 for multiple uses. The secondary structure grouting device of the utility model comprises a mother mold 01, a mold bucket 02 and a blocking plate 03. The blocking plate 03 is used to block the feeding port of the mold bucket 02. A mold bucket discharge port opening and closing assembly 05 is provided at the discharge port of the mold bucket 02. Therefore, when pouring concrete, until the horizontal line of the concrete reaches the highest bearing position of the mold bucket 02, the blocking plate 03 is closed downward to squeeze the concrete in the mold bucket 02, so that the top of the secondary structure template cavity is completely in contact with the bottom surface of the load-bearing beam, thereby solving the problem that the secondary structure and the top load-bearing beam cannot be completely fitted.

The top of the third side plate 23 is connected between the top of the first side edge of the first side plate 21 and the top of the first side edge of the second side plate 22. A gap 24 is left between the bottom of the third side plate 23 and the bottom of the second side edge of the first side plate 21 and the bottom of the second side edge of the second side plate 22. The gap 24 forms a discharge port. A second grouting port is formed between the second side edge of the first side plate 21 and the second side edge of the second side plate 22.

A pair of first threaded rods 502 are respectively connected to a threaded sleeve 501. The clamping plate 503 is clamped between the first threaded rod 502 and the bottom edge of the third side plate 23. The clamping plate 503 is used to block the feed port at the spacing 24. The leak plate 504 can be rotatably connected to the mother mold 01.

The other end of the rubber screw 71 is used to be inserted into the template wall of the secondary structure to be cast. The initial inner diameter of the rubber screw 71 is smaller than the outer diameter of the threaded rod 72. When fixing the mother mold 01, the rubber screw 71 is nailed into and penetrates the formwork wall of the secondary structure and contacts the inner wall of the hollow structure. Then, the threaded rod 72 is aligned with the rubber threaded nail 71, and the rotating handle 73 is manually turned. The rotating handle 73 drives the threaded rod 72 to be inserted into the rubber screw 71, so that the mother mold 01 is fixed on the formwork wall of the existing secondary structure.
