SUMMARY

[0003] The utility model discloses a steel strand butt joint anchorage device, which solves the above technical problems,

[0004] The utility model discloses the following technical scheme realizes: a steel strand butt joint anchorage device, including anchor ring and anchor block, anchor block is cooperated in anchor ring through conical surface, and anchor ring and anchor block are all connected with the steel strand of mutual opposite pull respectively through anchor head, and anchor ring is connected with the sleeve nut of hoop outside thread.

[0005] Further, the sleeve nuts are arranged at both ends of the anchor ring, and the thread directions of the sleeve nuts at both ends are opposite.

[0006] Preferably, the outer wall of the anchor ring is provided with a protruding ring for isolating the sleeve nuts at both ends.

[0007] Further, the anchor ring is divided into multiple clamping pieces, and each clamping piece is separately connected with a steel strand.

[0008] Further, the anchor block is in the shape of a conical frustum, a conical hole is formed in the anchor ring to cooperate with the anchor block, the anchor head connected with the anchor block abuts against the large-diameter end of the anchor block, and the anchor head connected with the anchor ring abuts against the small-hole end of the anchor ring.

[0009] Further, the anchor head is a P-shaped anchor head.

[0010] The utility model at least has following advantages and beneficial effects: through the conical surface cooperation of anchor ring and anchor block and the setting of sleeve nut, surface contact is always maintained, so that the anchorage device is stable under stress, good bearing capacity is realized, and the risk of loosening caused by tension is reduced.

[0016] The specific embodiment is combined below with the accompanying drawings.

[0017] Embodiment

[0018] As Figures 1-4 shown, in the embodiment, mainly disclose a kind of steel strand butt joint anchor device, simple and reliable structure, its main structure includes anchor ring 1 and anchor block 2, anchor block 2 is cooperated in anchor ring 1 by conical surface, anchor ring 1 and anchor block 2 are all connected with the steel strand 4 of mutual opposite pull respectively by anchor head 3, anchor ring 1 is connected with clamp sleeve nut 5 outside thread;Specifically, one side steel strand 4 is connected with anchor ring 1 by anchor head 3 by passing through anchor ring 1, another side steel strand 4 is connected with anchor block 2 by anchor head 3 by passing through anchor block 2, so that the stress direction of anchor block 2 and anchor ring 1 is opposite, forms opposite pull, and always keeps surface contact, force stability, realizes good carrying capacity, reduces loosening caused by tension.

[0019] Further, in specific implementation, the above-mentioned clamp sleeve nut 5 provided in the embodiment of the utility model is arranged at both ends of anchor ring 1 respectively, and the thread directions of the clamp sleeve nuts 5 at both ends are opposite;The arrangement of the clamp sleeve nut 5 can effectively increase the stability of the anchor device, avoid the reverse phenomenon under external force, thereby enhancing the safety and reliability of the entire anchor device;On the other hand, it effectively increases the radial clamping force of the anchor device to ensure stable connection.

[0020] Preferably, the outer wall of the anchor ring 1 is provided with a convex ring 11 for isolating the clamp sleeve nuts 5 at both ends;Not only can the clamp sleeve nuts 5 at both ends be isolated to prevent mutual interference, but also the shear resistance of the anchor device can be improved to some extent, the overall structural strength is enhanced, and wear caused by friction of part components is prevented.

[0021] Further, in specific implementation, the above-mentioned anchor ring 1 provided in the embodiment of the utility model is divided into multiple clips 12, and each clip 12 is separately connected to a steel strand 4;It can evenly distribute load, improve tensile strength, and also facilitate individual repair or replacement, thereby increasing the maintainability of the system.

[0022] Further, in the specific implementation, the anchor block 2 is in the form of a conical platform, a conical hole 10 cooperating with the anchor block 2 is formed in the anchor ring 1, the anchor head 3 connected with the anchor block 2 abuts against the large-diameter end of the anchor block 2, and the anchor head 3 connected with the anchor ring 1 abuts against the small-hole end of the anchor ring 1; a compact connection is formed, the overall stability of the anchorage device is enhanced, and the displacement risk under dynamic load is reduced.

[0023] Further, in the specific implementation, the anchor head 3 can be a P-shaped anchor head in the prior art.
