[0023] Please refer to Figs. 1-3 The present application provides a technical scheme: an anchoring device for a concrete column of a house building project, which comprises an anchor rod 1, and the same as the prior art, the outer ring of the front end of the anchor rod 1 is provided with a mounting thread 12, when used, a hole is opened on the surface of the concrete column, then a sufficient amount of anchoring agent is injected into the hole, and then the anchor rod 1 is inserted into the hole, so that the anchoring agent is wrapped around the rear end of the anchor rod 1, and after solidification, the anchor rod 1 can be fixed, and a nut can be used to cooperate with the mounting thread 12 of the front end of the anchor rod 1 to realize the installation and fixation of the equipment.

[0024] A ring block 11 is further provided around the rear end of the anchor rod 1, the ring block 11 is provided with multiple rings, when the anchor rod 1 is inserted into the hole, the anchoring agent can obtain a larger contact area with the anchor rod 1 through the ring block 11, so that the anchoring effect of the anchor rod 1 after solidification is better.

[0025] The difference from the prior art is that a sleeve 2 is arranged on the outer ring of the front end of the anchor rod 1, the rear end of the sleeve 2 is fixed with a stop plate 4, a first rod hole 41 is formed in the middle of the surface of the stop plate 4, the anchor rod 1 can slide through the stop plate 4 through the first rod hole 41, a self-tapping thread 21 is arranged around the outer ring of the sleeve 2, the diameter of the opening on the surface of the concrete column is slightly larger than the outer diameter of the sleeve 2, and the front end of the outer ring of the sleeve 2 is fixed with a front plate 3, an opening 31 is formed in the surface of the front plate 3 and communicates with the sleeve 2, and the front end surface of the front plate 3 above and below the opening 31 is welded and fixed with a side plate 32 perpendicular to the front plate 3.

[0026] When the anchor rod 1 is inserted into the opening and the anchor agent is not cured, the structure composed of the sleeve 2, the front plate 3 and the stop plate 4 is inserted into the opening from the front side to the anchor rod 1, and the front end of the anchor rod 1 penetrates the stop plate 4 through the first rod hole 41 and penetrates out of the front end from the opening 31 of the front plate 3, part of the sleeve 2 on the side of the stop plate 4 is inserted into the opening, then a wrench is clamped on the two side plates 32 to drive the front plate 3 and the sleeve 2 to rotate, so that the self-tapping thread 21 on the outer ring of the sleeve 2 acts on the inner wall of the opening, thereby screwing the sleeve 2 into the opening and pressing the anchor agent inward, so that the anchor agent is pressed to a compact state and fully contacts the anchor rod 1 and the outer ring block 11 thereof, until the sleeve 2 is completely screwed in and the front plate 3 is in contact with the outer surface of the concrete column, the excess anchor agent is extruded outwards from the gap between the anchor rod 1 and the first rod hole 41, so that the anchor agent can have sufficient anchoring strength to the anchor rod 1 after curing, and the first rod hole 41 on the surface of the stop plate 4 can maintain the support state of the front end of the anchor rod 1 before the anchor agent is cured, so as to avoid the front end of the anchor rod 1 from tilting downward due to gravity when the anchor agent is not cured.

[0027] A gasket 5 is also provided, the rear end of the gasket 5 is fixed with a rubber sleeve 52, the surface of the gasket 5 is provided with a second rod hole 51 for the front end of the anchor rod 1 to penetrate, the rubber sleeve 52 is inserted into the opening 31 after the outer ring of the anchor rod 1 is sleeved with the rubber sleeve 52 and the rear end is inserted into the opening 31, and a plurality of convex circles 521 are arranged around the outer ring of the rubber sleeve 52, so that the rubber sleeve 52 can be inserted into the opening 31 through the convex circles 521, and finally the gasket 5 is in contact with the front end of the side plate 32 to separate the side plates 32, and finally the installation screw thread 12 of the front end of the anchor rod 1 can be used for equipment installation.

[0028] In use, a hole is drilled in the surface of a concrete column at the desired anchoring position, the hole having a diameter slightly larger than the outer diameter of the sleeve 2. After cleaning, a sufficient amount of anchoring agent is injected into the hole. The anchoring rod 1 is separated from the sleeve 2, the front plate 3 and the stop plate 4 by pulling, and the end of the anchoring rod 1 containing the ring block 11 is inserted into the hole, with the anchoring agent wrapped around the outer circumference of the anchoring rod 1. Then, the structure formed by the sleeve 2, the front plate 3 and the stop plate 4 is inserted into the hole from the front side towards the anchoring rod 1, and the front end of the anchoring rod 1 passes through the first rod hole 41 of the stop plate 4, and protrudes out of the opening 31 of the front plate 3. The portion of the sleeve 2 on the side of the stop plate 4 is inserted into the hole. Then, a wrench is clamped on the two side plates 32 to rotate the front plate 3 and the sleeve 2, so that the self-tapping threads 21 on the outer circumference of the sleeve 2 act on the inner wall of the hole, thereby screwing the sleeve 2 into the hole and pressing the anchoring agent inward. This allows the anchoring agent to be compressed to a dense state and fully contact the anchoring rod 1 and the ring block 11 on the outer circumference thereof. The sleeve 2 is screwed in completely until the front plate 3 is in contact with the outer surface of the concrete column. The excess anchoring agent is squeezed out of the gap between the anchoring rod 1 and the first rod hole 41. The first rod hole 41 on the surface of the stop plate 4 then supports the front end of the anchoring rod 1 until the anchoring agent is completely cured. After that, the rubber sleeve 52 is sleeved on the outer circumference of the anchoring rod 1, and is inserted into the opening 31 towards the rear end, with the gasket 5 in contact with the front end of the side plate 32. Finally, the mounting threads 12 on the front end of the anchoring rod 1 are used to install equipment.
