Specifically, the support anchor is a support structure that binds the surrounding rock of tunnels, slopes or other underground structures together. By changing the mechanical state of the surrounding rock, an integral and stable rock belt is formed to achieve the purpose of maintaining the stability of structures such as tunnels and slopes.
[0003] At present, when using anchor rods, it is necessary to open pile holes on the construction surface in advance, and then the anchor rods are hoisted into the pre-opened pile holes, and then the space between the anchor rods and the pile holes is poured and filled to fix the anchor rods on the soil layer / construction surface, and then the anchor rods are used for building construction support. However, in the actual construction process, it is found that after the anchor rods are placed in the pre-opened pile holes, the anchor rods and the soil layer are only fixed by concrete filling, and there is a lack of limiting and force-bearing structures. The anchor rods are prone to loosening and falling off, and the stability of the building construction support is low.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] This embodiment provides an anchor device for building support construction, and its structural diagram is as follows: Figure 1 - Figure 4 When the anchor bolt 1 is in the working state, the anchor bolt 1 is fixed with a screw thread 7 and a screw thread 8 rotatable inside the anchor bolt 1. The screw thread 7 is fixed with a screw thread 7 and a screw thread 8 rotatable inside the anchor bolt 1. The screw thread 7 is fixed with a screw thread 7 and a screw thread 8 rotatable inside the anchor bolt 1. The screw thread 7 is fixed with a screw thread 7 and a screw thread 8 rotatable inside the anchor bolt 1.
[0022] Furthermore, in this embodiment, guide arms 6 are horizontally fixed at positions above and below the through slot 4 on the inner wall of the anchor rod body 1, and both ends of the connecting shaft 7 are slidably engaged with a pair of guide arms 6. Specifically, a pair of guide arms 6 are provided with a sliding groove 10 on the facing sides, and a slider 11 is slidingly arranged in the sliding groove 10. The two ends of the connecting shaft 7 are fixedly connected to the slider 11, which is conducive to the connecting shaft 7 pushing the excavation block 8 out of the through slot 4 under the push of the pushing member 9.
[0023] As a preferred technical solution in this embodiment, a return spring 12 is provided in the slide 10, and the return spring 12 is located on the side of the slider 11 facing the through groove 4. The pushing member 9 is a pair of pushing plates 15 horizontally fixed on the shaft 5. The pair of pushing plates 15 are symmetrically distributed, and the pair of pushing plates 15 are both semicircular structures. The connecting shaft 7 contacts the arc surface of the pushing plate 15. Through this structural method, when the shaft 5 drives the pushing plate 15 to rotate, the semicircular pushing plate 15 pushes the connecting shaft 7, forcing the excavation block 8 to extend out of the through groove 4 and push into the soil layer of the pile hole. When the connecting shaft 7 is at the end of the pushing plate 15 away from the shaft 5, The pushing plate 15 no longer pushes against the connecting shaft 7. At this time, the return spring 12 pushes the slider 11 to slide along the slide groove 10, driving the connecting shaft 7 and the excavation block 8 to be retracted into the anchor rod body 1, and as the pushing plate 15 continues to rotate, the excavation block 8 is pushed out of the through groove 4 and into the soil layer again. In this way, after the anchor rod body 1 is placed in the pile hole, it can excavate a groove aligned with the through groove 4 on the soil layer. After the anchor rod body 1 is poured with concrete, the concrete flows from the through groove 4 into the gap between the anchor rod body 1 and the pile hole, and also flows into the groove excavated in the soil layer aligned with the through groove 4. After the concrete solidifies, the stability of the anchor rod body 1 is further improved.
[0024] Furthermore, in this embodiment, a shaft sleeve 13 is rotatably provided on the shaft rod 5, and a fixed support rod 14 is fixed on the side wall of the shaft sleeve 13. The fixed support rod 14 is fixed on the inner wall of the anchor rod body 1 and is used for rotational positioning of the shaft rod 5. A cone head 2 is provided at the bottom end of the anchor rod body 1 to facilitate the lifting of the anchor rod body 1 into the pile hole. A ring seat 3 is provided at the top end of the anchor rod body 1, and a mounting hole 17 is opened on the ring seat 3 for fixing the top end of the anchor rod body 1. The top end of the shaft rod 5 extends to the ring seat 3 and is fixed with a connecting plate 16 for connecting with the driving equipment.
[0025] Working principle: When in use, the anchor rod body 1 is hoisted into the pile hole pre-drilled at the construction site, and then the shaft rod 5 is connected to the driving device such as the motor by using the connecting plate 16. The driving device drives the shaft rod 5 to rotate, and the shaft rod 5 drives the pushing plate 15 to rotate. The semicircular pushing plate 15 pushes against the connecting shaft 7, forcing the excavation block 8 to extend out of the through groove 4 and push into the soil layer of the pile hole. When the connecting shaft 7 is at the end of the pushing plate 15 away from the shaft rod 5, the pushing plate 15 no longer pushes against the connecting shaft 7. At this time, the reset spring 12 pushes the slider 11 to slide along the slide groove 10, driving the connecting shaft 7 to move. The shaft 7 and the tunneling block 8 are retracted into the anchor rod body 1, and as the pushing plate 15 continues to rotate, the tunneling block 8 is pushed out of the through groove 4 and into the soil layer again. In this way, after the anchor rod body 1 is placed in the pile hole, it can dig a groove aligned with the through groove 4 on the soil layer. After the anchor rod body 1 is poured with concrete, the concrete flows from the through groove 4 into the gap between the anchor rod body 1 and the pile hole and the groove aligned with the through groove 4 dug on the soil layer. After the concrete solidifies, the anchor rod body 1 can be tightly combined with the soil layer, thereby improving the stability of the anchor rod body 1, and thereby enhancing the stability of the anchor rod body 1 for supporting construction.
[0026] All technical features in this embodiment can be freely combined according to actual needs.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
