In order to make the contents of the present utility model more clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Referring to fig. 1-3, an adjustable fastening degree steel strand anchor comprises a clamp main body 1, an anchor end cover 2, an adjusting screw sleeve 3 and a heart-shaped clamp 4, wherein an external thread 5 is arranged outside the clamp main body 1, the anchor end cover 2 and the adjusting screw sleeve 3 are respectively in threaded connection with two ends of the external thread 5, a conical hole 6 is formed in the clamp main body 1, the heart-shaped clamp 4 is conical matched with the conical hole 6 in a taper manner, one end of the heart-shaped clamp 4 is embedded in the conical hole 6, and the other end of the heart-shaped clamp 4 can be pushed by the anchor end cover 2.

In this embodiment, the end of the anchor end cover 2 near the clamp body 1 is provided with a connecting cavity 7, the end of the anchor end cover 2 far away from the clamp body 1 is provided with a through hole 8 communicated with the connecting cavity 7, and one end of the heart-shaped clamp 4 positioned on the anchor end cover 2 is abutted against the inner end wall of the connecting cavity 7, the heart-shaped clamp 4 is formed by splicing at least three clamp bodies 4-1, the outer wall of each clamp body 4-1 is wedge-shaped, the inner wall of each clamp body 4-1 is provided with an internal thread 4-2 matched with an external thread rib of a steel bar, and when the anchor end cover 2 is rotated, the movement affects the position of the heart-shaped clamp 4, so that the fastening degree of a steel strand is adjusted. Along with the rotation of the anchor end cover 2, the clamping piece bodies 4-1 can move towards the inside of the conical hole 6, and due to the design of wedge-shaped outer walls between the clamping piece bodies 4-1, the wedge-shaped outer walls are mutually close, so that the gap between the clamping piece bodies 4-1 for the steel strand to pass through is reduced, the effect of adjustable fastening degree is achieved, and the inner wall of each clamping piece body 4-1 is provided with an inner thread 4-2 matched with the external thread rib of the steel strand, so that the steel strand is firmly fixed.

In this embodiment, in order to prevent loosening of the anchor end cover 2, the anchor end cover 2 is screwed with a tightening screw 9, the pushing end of the tightening screw 9 extends into the connecting cavity 7 and is locked on the external screw thread 5, after the anchor end cover 2 rotates at a certain position, the tightening screw 9 is turned, and the pushing end of the tightening screw 9 is locked on the external screw thread 5, so that the anchor end cover 2 can be prevented from being turned again.

Working principle: first, the steel strands need to pass through the different components of the anchorage in sequence. The anchor end cap 2 is first passed through the through hole 8 communicating with the connecting cavity 7 from the end thereof remote from the clamp body 1, then through the gap of the heart-shaped clamp 4, and finally out from the end of the adjusting screw sleeve 3. When the steel strand passes through the heart-shaped clamp 4, the design of the heart-shaped clamp plays a key role. The heart-shaped clamp 4 is formed by splicing at least three clamp bodies 4-1, the outer wall of each clamp body 4-1 is wedge-shaped, and the inner wall is provided with an inner thread 4-2 which is matched with the external thread rib of the steel bar. When the anchor end cap 2 is rotated, the inner end face of the anchor end cap 2 abuts against the end face of the three-piece clamp body 4-1. Along with the rotation of the anchor end cover 2, the clamping piece bodies 4-1 can move towards the inside of the conical holes 6, and due to the design of wedge-shaped outer walls between the clamping piece bodies 4-1, the clamping piece bodies can be mutually close to each other, so that gaps between the clamping piece bodies 4-1 for the steel strands to pass through are reduced, and the effect of adjustable fastening degree is achieved. The adjustment mechanism can control the fastening degree of the steel strand by rotating the anchor end cover 2, so as to adapt to different engineering requirements. In order to prevent loosening of the anchor end cap 2, the anchor end cap 2 is provided with a jacking screw 9, and the pushing end of the jacking screw 9 extends into the connecting cavity 7 and is locked on the external thread 5. When the anchor end cap 2 is rotated to a desired position, the jack screw 9 is rotated to lock its driving end to the external thread 5, thereby preventing the anchor end cap 2 from being rotated again. The design ensures that the positioning of the heart-shaped clamp is more stable, and simultaneously ensures the whole tightness of the anchorage device.

The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
