Description

Technical Field

[0001] This utility model relates to the field of steel strand anchor technology, and in particular to an adjustable-angle anchor. Background Technology

[0002] In the field of engineering anchoring, the angular adaptability of anchors directly affects the structural safety and service life of engineering structures. Traditional anchors generally adopt a fixed angle design. When the load direction deviates from the anchor axis, it leads to the following problems: 1. Significantly increased risk of stress concentration: Deviated loads cause the anchor rod to bear non-axial bending moments, easily leading to anchor rod breakage, steel strand slippage, or wedge cracking. 2. Potential for concrete structural damage: The fixed angle design causes the anchor to exert eccentric pressure on the concrete, resulting in local crushing or cracking of the concrete. Especially in geotechnical anchoring projects, soil displacement under complex geological conditions can easily cause the anchor to deviate from the direction of force on the structure, exacerbating concrete damage. 3. Severely insufficient dynamic adaptability: Some existing adjustable anchors rely on manual adjustment and cannot cope with real-time angle changes caused by dynamic loads such as wind vibration and earthquakes. 4. Difficulty in meeting engineering needs in complex environments: With the development of new energy projects and the construction of long-span bridges, anchoring scenarios have shifted from single axial force to multi-directional dynamic force. Traditional anchors, due to their lack of angle adjustment capability, have become a bottleneck restricting the safety and economy of engineering projects. Therefore, developing an anchor structure that requires no manual intervention and can dynamically and adaptively adjust its angle is of urgent engineering significance for improving anchoring performance under complex working conditions. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable-angle anchor, which can solve the problem that traditional anchors generally adopt a fixed-angle design and cannot meet the engineering needs in complex environments.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: This adjustable-angle anchor includes, from top to bottom, a self-locking end cap, a self-locking anchor cup, an anchor cup pad, and a steering pad; the steering pad has a first through hole, the anchor cup pad has a second through hole, and the top of the anchor cup pad has a downwardly recessed arc-shaped transition surface around the second through hole; the self-locking anchor cup has a receiving cavity that is larger at the top and smaller at the bottom, and a clamping plate assembly is inserted into the receiving cavity; the upper part of the self-locking anchor cup has an external thread, and the self-locking... The bottom of the self-locking anchor cup has a downwardly protruding arc-shaped contact surface, through which the self-locking anchor cup can rotate on the arc-shaped transition surface; the self-locking end cap is cylindrical, and a partition is provided inside the self-locking end cap, with a third through hole on the partition; the self-locking end cap has an internal thread corresponding to the external thread on the side wall below the partition, and the lower surface of the partition abuts against the upper surface of the clamping plate assembly; the first through hole, the second through hole, the receiving cavity, and the third through hole are coaxially arranged.

[0005] A more specific technical solution in the above technical solution is that the clamping plate assembly is conical and is formed by two steel strand clamping plates, the thickness of which gradually decreases from top to bottom.

[0006] Furthermore, the inner wall of the clip assembly is provided with anti-slip serrations, and the upper outer wall of the clip assembly is provided with an annular groove for placing the iron ring.

[0007] Furthermore, the inner diameter of the second through hole is larger than the bottom inner diameter of the receiving cavity.

[0008] Furthermore, the steering pad is provided with pins on both sides for hinged connection with the fixed support.

[0009] Furthermore, the self-locking anchor cup is made of high-strength alloy material.

[0010] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0011] When the tension direction of the steel strand deviates and the load direction is at an angle to the anchor axis, this invention uses a self-locking anchor cup to deflect on the anchor cup pad and a steering pad to deflect on the fixed support, so that the force direction of the anchor is always perpendicular to the steering pad, keeping the force direction of the anchor consistent with the tension direction of the steel strand. Dynamic adaptive adjustment can be achieved without manual intervention, avoiding stress concentration and potential damage to the concrete structure, and meeting the engineering needs in complex environments.

[0017] like Figure 1 and Figure 2 The adjustable-angle anchor shown includes, from top to bottom, a self-locking end cap 1, a self-locking anchor cup 2, an anchor cup pad 3, and a steering pad 4; the steering pad 4 has a first through hole, the anchor cup pad 3 has a second through hole, and the top of the anchor cup pad 3 has a downwardly recessed arc-shaped transition surface around the second through hole; the self-locking anchor cup 2 has a receiving cavity that is larger at the top and smaller at the bottom, and a clamping plate assembly 5 is inserted into the receiving cavity; the upper part of the self-locking anchor cup 2 has an external thread, and the bottom of the self-locking anchor cup 2 has a downwardly convex arc-shaped... Contact surface 2-1, the self-locking anchor cup 2 can rotate on the arc-shaped transition surface through the arc-shaped contact surface 2-1; the self-locking end cap 1 is cylindrical, and a partition 6 is provided inside the self-locking end cap 1. A third through hole is provided on the partition 6. An internal thread corresponding to the external thread is provided on the side wall below the partition 6 of the self-locking end cap 1. The lower surface of the partition 6 abuts against the upper surface of the clamping plate assembly 5; the first through hole, the second through hole, the receiving cavity and the third through hole are coaxially arranged, and the inner diameter of the second through hole is larger than the bottom inner diameter of the receiving cavity.

[0020] In use, the steel strand 9 passes through the receiving cavity of the self-locking anchor cup 2, the second through hole of the anchor cup pad 3, and the first through hole of the steering pad 4. Then, the clamping plate assembly 5 is inserted into the receiving cavity of the self-locking anchor cup 2 to clamp the steel strand 9. An iron ring is placed in the annular groove 5-1 of the clamping plate assembly 5 so that when the steel strand 9 is under force, the two steel strand clamping plates move in together to clamp the steel strand 9. The self-locking end cap 1 is then threaded to the self-locking anchor cup 2. The steel strand 9 passes through the third through hole of the partition plate 6. Finally, the present invention, with the steel strand 9 clamped, is installed on the fixed support 8. The anchor cup pad 3 can be placed directly on the steering pad 4 or fixed to the steering pad 4.

[0021] When the tension direction of the steel strand deviates and the load direction is at an angle to the anchor axis, this utility model uses the self-locking anchor cup 2 to deflect on the anchor cup pad 3 and the deflecting pad 4 to deflect on the fixed support 8, so that the force direction of the anchor is always perpendicular to the deflecting pad 4, keeping the force direction of the anchor consistent with the tension direction of the steel strand 9. Dynamic adaptive adjustment can be achieved without manual intervention, avoiding stress concentration and potential damage to the concrete structure, and meeting the engineering needs in complex environments.
