Description

Technical Field

[0001] The utility model relates to the technical field of anchoring brackets, in particular to a geotechnical anchoring bracket convenient for installation. Background Technique

[0002] The basic principle of geotechnical anchoring is to utilize the shear strength of the rock and soil around the anchor rod to transfer the tensile force of the structure to maintain the self-stability of the excavation surface of the stratum. In geotechnical anchoring, the anchor rod and the cable are usually collectively referred to as the anchor rod. The anchor rod is a structural system that transmits the tensile force to the stable rock stratum or soil layer, mainly composed of an anchor head, a free section, and an anchoring section. This anchoring bracket is a component used for insertion into a preset anchor hole.

[0003] The existing anchoring brackets are not convenient enough to install. In addition, loosening may occur over time after installation, resulting in a decrease in stability.

[0004] Therefore, it is particularly important to design a geotechnical anchoring bracket convenient for installation to change the above technical defects and improve the overall practicality. Content of the Utility Model

[0024] A geotechnical anchoring bracket that is convenient for installation, including an anchor rod 1. A limit top plate 2 is arranged at the top of the anchor rod 1. A threaded short rod 3 is welded at the center of the top of the limit top plate 2. A reinforcing lock nut 4 is threadedly sleeved on the outer side of the threaded short rod 3. A connecting bracket 401 is fixed at the top of the reinforcing lock nut 4. Side support plates 402 are connected to the bottoms of the left and right sides of the reinforcing lock nut 4 respectively. An auxiliary insertion rod 403 penetrating through the inside of the limit top plate 2 is arranged inside the side support plate 402. Extension wing plates 5 are connected to the left and right sides of the limit top plate 2 respectively. Fixed taper rods 501 are inserted into the extension wing plates 5. Cross through holes 6 are formed in the anchor rod 1 for the fixed taper rods 501 to penetrate and be inserted. The left fixed taper rod 501 is sequentially inserted into the cross through holes 6 of the extension wing plate 5 and the anchor rod 1, and then the right fixed taper rod 501 is sequentially inserted into the cross through holes 6 of the extension wing plate 5, the anchor rod 1 and the insertion hole of the left fixed taper rod 501. The added two groups of fixed taper rods 501 increase the left and right cross forces during the fixation of the anchor rod 1, greatly improving the connection force between the anchor rod 1 and the soil;

[0025] Among them, a detachable connection design is adopted between the reinforcing lock nut 4 and the connecting bracket 401 through bolts. Through holes for the auxiliary insertion rods 403 to be movably inserted are formed in the left and right sides inside the limit top plate 2. A detachable structure design is adopted between the auxiliary insertion rods 403 and the limit top plate 2 and the side support plates 402 respectively. The extension wing plates 5 are of an inclined structure design. The two groups of fixed taper rods 501 are inserted into the extension wing plates 5 and the inside of the anchor rod 1 in an inclined state. An insertion hole for the right fixed taper rod 501 to pass through is formed in the left fixed taper rod 501. A detachable structure is adopted between the fixed taper rods 501 and the anchor rod 1 and the extension wing plates 5 respectively through a plug-in connection design.

[0026] Working process of the utility model: When installing and fixing the geotechnical anchoring bracket, the whole anchor rod 1 is placed into the anchor hole. Then, the fixing cone rod 501 on the left is inserted into the cross through holes 6 of the extended wing plate 5 and the anchor rod 1 in sequence. Next, the fixing cone rod 501 on the right is inserted into the cross through holes 6 of the extended wing plate 5, the anchor rod 1, and the insertion hole of the left fixing cone rod 501 in sequence. The two additional groups of fixing cone rods 501 increase the left-right cross force during the fixation of the anchor rod 1, greatly improving the connection force between the anchor rod 1 and the soil. Then, the reinforcement lock cap 4 is threadedly connected to the short threaded rod 3, and the side support plate 402 is attached to the top of the limit top plate 2. Then, multiple groups of auxiliary insertion rods 403 are inserted into the side support plate 402 and the through holes and finally inserted into the soil to increase the grasping force with the ground. Finally, the reinforcement lock caps 4 at the tops of multiple groups of anchor rods 1 can be connected through the connection bracket 401 to improve the overall endurance.
