[0002] A construction project refers to an engineering entity formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities. Anchoring devices are devices used in building renovation projects, and their purpose is to fix rear anchors in the building structure.

[0003] The existing rear anchoring devices are widely used. When in use, a hole is usually made in the ground or wall first, and then the rear anchor is placed in the hole. Finally, the screw on the anchor is turned to complete the anchoring. However, when the screw is turned, the anchor will rotate as a whole, resulting in the screw being unable to be tightened. Manual positioning is required, which is quite dangerous. In addition, the existing rear anchor is usually anchored by overall expansion and fixed by friction. This anchoring method is not stable enough and is prone to loosening due to insufficient friction. The materials of some locations that need to be fixed are relatively soft, and the anchoring will fail because physical anchoring is not applicable. Therefore, in view of the above problems, a rear anchoring device for building renovation projects is proposed. Utility Model Content

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] A rear anchoring device for engineering purposes comprises an anchor 1, a positioning plate 2 fixedly connected to the anchor 1 is symmetrically arranged on the outer side of the anchor 1, a positioning hole 3 penetrating the positioning plate 2 from front to back is arranged on the inner side of the positioning plate 2, a thread groove 4 is arranged on the front side of the anchor 1, a cylindrical groove 5 penetrating the thread groove 4 is arranged on the inner side of the anchor 1, a screw 6 is spirally connected to the inner side of the thread groove 4, a solid frustum 7 is arranged on the inner side of the cylindrical groove 5, a connecting plate 8 which is inclined and fixedly connected to the inner side of the cylindrical groove 5 is arranged on one side of the solid frustum 7, a conical thorn 9 is fixedly connected to the outer side of the connecting plate 8, a through hole 10 penetrating the cylindrical groove 5 is arranged on the outer side of the anchor 1, and a reinforcing component 11 is arranged on the rear side of the anchor 1.

[0024] The reinforcing component 11 includes a circular hole 1101 which is opened at the rear side of the anchor 1 and passes through the cylindrical groove 5. A horizontally arranged sliding rod 1102 is arranged inside the circular hole 1101. A disc 1103 is fixedly connected to the end of the sliding rod 1102 away from the anchor 1. A connecting rod 1104 fixed to the disc 1103 is arranged outside the sliding rod 1102. A liquid storage tank 1105 fixedly connected to the anchor 1 is arranged at the end of the connecting rod 1104 away from the disc 1103. A baffle 1106 is fixedly connected to the inner side of the liquid storage tank 1105. The reinforcing component 11 enables the anchor 1 to adapt to substrates of more materials. The circular hole 1101 and the sliding rod 1102 are connected in a sliding manner. One end of the sliding rod 1102 away from the disc 1103 is fixedly connected to the solid cone 7. There are multiple connecting rods 1104, which are distributed in an array on one side of the disc 1103. The connecting rods 1104 can pierce the liquid storage tank 1105 and the baffle 1106. The shape of the anchor 1 is cylindrical. The connection method between the screw 6 and the solid cone 7 is a rotational connection. The solid cone 7 can squeeze the connecting plate 8 on its outer side so that the conical thorn 9 slides inside the through hole 10 and penetrates into the wall. There are multiple connecting plates 8, which are distributed in an array on the inner side of the cylindrical groove 5. The conical thorn 9 is located inside the through hole 10 and is aligned with the through hole 10.

[0025] Workflow: When anchoring is required, first use an electric drill to drill a hole on the wall, put the anchor 1 into the hole, then use a nail to pass through the positioning hole 3 on the positioning plate 2, and nail the nail into the wall. At this time, the nail can position the anchor 1 to prevent the anchor 1 from rotating when the screw 6 is tightened. Next, turn the screw 6 to rotate inside the thread groove 4 and move outward. At this time, the solid frustum 7 on the inside of the cylindrical groove 5 moves with the screw 6, and the solid frustum 7 squeezes the connecting plate 8 on its outside, so that the outside of the connecting plate 8 gradually fits tightly with the inside of the cylindrical groove 5. At this time, the conical thorn 9 on the outside of the connecting plate 8 passes through the hole 10 The inner side slides and penetrates into the inner side of the wall. The design of multiple conical thorns 9 can increase the contact area with the inner side of the wall and increase the stability of the anchor 1. When the screw 6 moves, the sliding rod 1102 slides inside the circular hole 1101 and drives the disc 1103 to move. The connecting rod 1104 follows the movement of the disc 1103 to pierce the liquid storage tank 1105 and the baffle 1106. The epoxy resin and hardener in the two chambers inside the liquid storage tank 1105 are mixed and immersed in the substrate. After curing, they can provide strong bonding force to make the screw 6 tightly combined with the substrate. The reinforcing component 11 enables the anchor 1 to adapt to substrates of more materials.
