Description

Technical Field

[0001] The utility model relates to the technical field of anchor rods, in particular to a capsule-type expanded anchor rod. Background Art

[0002] In the field of geotechnical engineering, capsule-type expanded anchor bolts are widely used due to their excellent anchoring effect and adaptability. However, traditional capsule-type expanded anchor bolts have some disadvantages in design and use.

[0003] Specifically, the bladder is usually fixed and welded on the rod body, and cannot be flexibly adjusted according to engineering requirements. In addition, during the grouting process of filling the bladder, the through holes opened on the rod body ensure that the concrete can flow smoothly into the bladder, but in actual construction, due to the fixed position of the bladder, not all through holes need to be opened at the same time. This results in some through holes not being effectively utilized during the grouting process, which not only wastes concrete materials, but also may affect the overall performance of the anchor rod. Therefore, a bladder-type expanded anchor rod is proposed to solve the above-mentioned problems. Utility Model Content

[0025] See also Figure 1-3 A capsule-type expansion anchor rod comprises a rod body 1, a capsule 4 and a capsule adjustment assembly, wherein the capsule 4 is arranged outside the rod body 1 near its end, a cone 2 is arranged at the end of the rod body 1, and a capsule adjustment assembly is arranged between the outside of the rod body 1 and the capsule 4;

[0026] The capsule adjustment assembly includes a rotating body 3 and a stopper 6. The rotating body 3 is arranged outside the rod body 1 and one side of the rotating body 3 is rotatably connected to one side of the capsule 4. The other end of the capsule 4 is welded to the rod body 1. The stopper 6 is also arranged outside the rod body 1 and one side of the rotating body 3 is rotatably connected to the other side of the rotating body 3.

[0027] In this embodiment, a threaded section 101 is disposed on the outside of the rod body 1 and is threadedly connected to the rotating body 3 via the threaded section 101 . The inner diameters of the capsule 4 and the stopper 6 are both larger than the outer diameter of the rod body 1 plus the threaded section 101 .

[0028] It should be noted that this design enables the rotating body 3 to move up and down along the threaded section 101 of the rod body 1, thereby driving the capsule 4 connected thereto to adjust its position accordingly. This adjustment method is simple and efficient, and the position of the capsule 4 can be flexibly adjusted according to specific engineering requirements, thereby enhancing the applicability of the anchor rod.

[0029] In this embodiment, two groups of through holes 102 are arranged on the outside of the rod body 1 and start from the bottom of the rod body 1 and end at the top of the threaded segment 101. The two groups of through holes are symmetrically distributed and located on the same horizontal plane.

[0030] It should be noted that the arrangement design of the through holes 102 ensures that the concrete can flow evenly into the bladder 4 during grouting, thereby ensuring the even expansion of the bladder 4 and the stability of the anchor rod.

[0031] In this embodiment, two guide grooves 103 are further provided on the outside of the rod body 1 . The two guide grooves 103 are symmetrically distributed and the planes where the two guide grooves 103 are located are perpendicular to the planes where the two groups of through holes 102 are located.

[0032] It should be noted that the guide groove 103 cooperates with the guide block on the inner wall of the block 6, so that the block 6 can slide smoothly along the rod body 1. This design not only ensures the stability of the block 6 during movement, but also enables the block 6 to be accurately positioned at the position of the through hole 102 that needs to be blocked, effectively preventing the waste of concrete.

[0033] In this embodiment, two symmetrically distributed guide blocks are provided on the inner wall of the stopper 6 , and the guide blocks are slidably connected to the guide grooves 103 . An annular rotating block 5 is provided on the side of the stopper 6 and the capsule 4 facing the rotating body 3 .

[0034] It should be noted that the sliding connection between the guide block and the guide groove 103 ensures the stability and accuracy of the stopper 6 during movement. At the same time, the design of the guide block also enables the stopper 6 to maintain a certain rigidity during movement to prevent deformation or displacement due to concrete pressure during the grouting process.

[0035] In this embodiment, a threaded through hole 301 is provided in the middle of the rotating body 3 , and annular rotating grooves 302 are provided on both sides of the rotating body 3 . The annular rotating block 5 is rotatably connected to the annular rotating grooves 302 .

[0036] It should be noted that the design of the threaded through hole 301 enables the rotating body 3 to be tightly connected to the rod body 1 through the threaded section 101 and realize the function of moving up and down. The annular rotating groove 302 provides a rotating space for the annular rotating block 5, so that the capsule 4 can move without rotating under the drive of the rotating body 3, effectively avoiding the entanglement problem of the capsule 4. This design ensures the flexibility of the capsule 4 and ensures its stability and reliability.

[0037] Beneficial effects:

[0038] The bladder-type expanded anchor rod is welded and fixed to the rod body 1 on one side of the bladder 4, thereby ensuring the stability and reliability of the structure; and the other side is rotatably connected to the rotating body 3, so that the bladder 4 can move with the movement of the rotating body 3, but will not rotate with it, effectively avoiding the entanglement problem that may occur in the bladder 4 during the rotation process. In addition, the through hole 102 opened on the rod body 1 provides a channel for grouting, but due to the flexibility of the design, not all through holes will be used during grouting. At this time, the block 6 is slidably connected to the guide groove 103 on the rod body 1 through the guide block on its inner wall, and can be accurately positioned with the movement of the rotating body 3 to cover the unused through hole 102, thereby avoiding the waste of concrete and improving the grouting efficiency.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
