Description

Technical Field

[0001] This utility model relates to the field of anchor bolt technology, specifically an anti-buoyancy anchor bolt structure. Background Technology

[0002] Anti-buoyancy anchors are a type of anti-buoyancy measure for underground structures in building engineering. They refer to structural components installed to resist the upward displacement of the building above. Anti-buoyancy anchors differ from ordinary foundation piles, possessing their own unique properties. The biggest difference between them is that foundation piles are typically compression piles, bearing the pressure of the building load, with the force transmitted from the top to the bottom of the pile, and the magnitude of the force on the pile changing with the building load; while anti-buoyancy piles are tension piles, bearing tensile force. Although the force on ordinary anti-buoyancy piles is also transmitted from the top to the bottom of the pile, and the magnitude of the force on the pile changes with the groundwater level, the force mechanisms of the two are exactly opposite.

[0003] Currently, to achieve the anti-buoyancy effect, existing anti-buoyancy anchors are equipped with anti-buoyancy components, such as an anti-buoyancy anchor with publication number CN209891202U. The anti-buoyancy anchor includes a concrete pipe pile and a bundle of pull-out reinforcing bars inserted into the concrete pipe pile. The pull-out reinforcing bar bundle includes several main pull-out reinforcing bars and short reinforcing bars spaced apart along the length of the main pull-out reinforcing bars. The bars of the short reinforcing bars are welded and fixed to the bars of each main pull-out reinforcing bar. The bottom of the pull-out reinforcing bar bundle is provided with an end plate, and the side of the end plate away from the pull-out reinforcing bar bundle is provided with an end tip.

[0004] However, the anti-buoyancy components added to existing anti-buoyancy anchors have a fixed shape and do not have a good adjustment effect. When installed in anchor holes of different diameters, their anti-buoyancy effect is limited. Therefore, it is urgent to design an anti-buoyancy anchor structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an anti-buoyancy anchor structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-buoyancy anchor structure includes an anchor body, a connecting rod fixed to the bottom of the anchor body, and a cavity inside the connecting rod. Multiple rows of equally spaced inlets and outlets are provided between the inner circumferential wall of the cavity and the outer wall of the connecting rod. Mounting seats are fixed at both ends of the bottom side of each inlet and outlet. The inner walls of two adjacent mounting seats are rotatably connected by pins to anti-buoyancy rods fitted inside the inlets and outlets. An angle adjustment component for adjusting the inclination of the anti-buoyancy rods is provided inside the cavity.

[0008] Furthermore, a threaded groove is provided at the bottom center of the cavity, and a threaded rod is screwed onto the inner wall of the threaded groove, with an anchor head fixed at the bottom of the threaded rod.

[0009] Furthermore, the angle adjustment assembly includes a cross that moves to the middle position of the inner wall of the cavity, and a movable disc that fits against the bottom inner wall of the cavity is fixed at the bottom of the cross. A connecting groove is opened at the middle position of the bottom of the movable disc. A bearing is provided between the inner wall of the connecting groove and the top of the threaded rod. Multiple rows of equally spaced toothed grooves are opened on all four sides of the cross, and a missing gear is fixed at the bottom of the anti-buoyancy rod, which meshes with the toothed groove.

[0010] Furthermore, a guide groove is provided at the top center of the cross, and a guide rod inserted into the guide groove is fixed at the top inner wall center of the cavity, with a spring fixed at the bottom of the guide rod and the bottom of the guide groove.

[0011] Furthermore, the anchor head has equidistantly distributed operating grooves on its circumferential outer wall.

[0012] Furthermore, an annular groove is provided at the bottom of the outer wall of the connecting rod, and a connecting ring fitted into the annular groove is fixed at the top of the anchor head.

[0013] Furthermore, the outer wall of the anchor bolt body is provided with a grout stop plug, and the outer wall of the anchor bolt body is provided with a pad plate located above the grout stop plug. A nut located on the pad plate is screwed onto the outer wall of the anchor bolt body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this utility model, the entire anti-buoyancy rod structure is composed of the anchor rod body, grout stop plug, pad, nut, connecting rod, anchor head, anti-buoyancy rod, and angle adjustment component. Before inserting the entire anchor rod into the anchor hole, the anchor head can be rotated to adjust the height of the threaded rod in the thread groove and the height of the cross in the angle adjustment component. The meshing action of the tooth groove and the missing gear drives the anti-buoyancy rod to rotate out from the inlet and outlet, so that multiple layers of anti-buoyancy components are set around the connecting rod to achieve the anti-buoyancy effect of the anchor rod.

[0016] In this invention, the angle adjustment component can, on the one hand, adjust the tilt angle of the anti-buoyancy rod, thereby adjusting the anti-buoyancy area of ​​the anti-buoyancy rod, facilitating anti-buoyancy operation in anchoring holes of different diameters and improving the performance. On the other hand, it can initially keep the anti-buoyancy rod in a retracted state, ensuring that the connecting rod and even the entire anchor rod surface are flat and easy to stack.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6In this embodiment of the present invention, an anti-buoyancy anchor structure includes an anchor body 1. A grout stopper 2 is provided on the outer wall of the anchor body 1, and a pad 3 is provided on the outer wall of the anchor body 1 above the grout stopper 2. A nut 4 is screwed onto the outer wall of the anchor body 1 on the pad 3. A connecting rod 5 is fixed to the bottom of the anchor body 1, and a cavity 13 is provided inside the connecting rod 5. Multiple rows of equally spaced inlets and outlets 9 are provided between the inner circumference of the cavity 13 and the outer wall of the connecting rod 5. Mounting seats 18 are fixed to both ends of one bottom side of each inlet and outlet 9. An anti-buoyancy rod 10 is rotatably connected to the inner walls of two adjacent mounting seats 18 via pins and fits within the inlet and outlet 9. An angle adjustment component for adjusting the inclination of the anti-buoyancy rod 10 is provided inside the cavity 13. A threaded groove 19 is provided at the middle of the bottom of the cavity 13, and a threaded rod 12 is screwed onto the inner wall of the threaded groove 19. The bottom of the threaded rod 12... An anchor head 7 is fixed. The angle adjustment component includes a cross 11 that moves in the middle of the inner wall of the cavity 13. The bottom of the cross 11 is fixed with a movable disc 14 that fits against the bottom inner wall of the cavity 13. A connecting groove is opened in the middle of the bottom of the movable disc 14. A bearing 23 is provided between the inner wall of the connecting groove and the top of the threaded rod 12. Multiple rows of equally spaced toothed grooves 21 are opened on all four sides of the cross 11. The bottom end of the anti-buoyancy rod 10 is fixed with a missing gear 17. The missing gear 17 meshes with the toothed groove 21. Adjusting the height of the cross 11 in the angle adjustment component, in conjunction with the meshing action of the toothed groove 21 and the missing gear 17, drives the anti-buoyancy rod 10 to rotate out from the inlet / outlet 9. This results in multiple layers of anti-buoyancy components around the connecting rod 5, achieving the anti-buoyancy effect of the anchor rod. The anti-buoyancy area of ​​the anti-buoyancy rod 10 can be adjusted, facilitating anti-buoyancy operation in anchoring holes of different diameters and improving the performance.

[0026] Specifically, a guide groove 22 is provided at the top center of the cross 11, and a guide rod 16 inserted into the guide groove 22 is fixed at the top inner wall center of the cavity 13. A spring 15 is fixed at the bottom of the guide rod 16 and the bottom of the guide groove 22. The guiding action of the guide rod 16 and the guide groove 22 ensures the stability of the cross 11 in raising and lowering, and the anti-buoyancy rod 10 is in a contracted state in the initial state under the action of the spring 15, ensuring that the connecting rod 5 and even the entire anchor rod surface are flat and easy to stack.

[0027] Specifically, the outer circumference of the anchor head 7 is provided with equally spaced operating grooves 8, which, in conjunction with a wrench, facilitate the rotation of the anchor head 7.

[0028] Specifically, an annular groove 20 is provided at the bottom of the outer wall of the connecting rod 5, and a connecting ring 6 is fixed at the top of the anchor head 7 and fits into the annular groove 20. The anchor head 7 is protected by the connecting ring 6 to prevent external forces from causing the threaded rod 12 or even the anchor head 7 to bend.

[0029] The working principle of this utility model is as follows: Before inserting the entire anchor rod into the anchoring hole, the user first uses a wrench in conjunction with the operating groove 8 to rotate the anchor head 7, thereby rotating the threaded rod 12. The height of the threaded rod 12 in the threaded groove 19 is adjusted, and the height of the cross 11 in the angle adjustment component is adjusted. With the meshing action of the tooth groove 21 and the missing gear 17, the anti-buoyancy rod 10 is rotated out from the inlet and outlet 9. The tilt angle of the anti-buoyancy rod 10 is adjusted, thereby adjusting the anti-buoyancy area of ​​the anti-buoyancy rod 10, which facilitates anti-buoyancy operation in anchoring holes of different diameters.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
