An adjustable steel wire cable anchor

Abstract

The present invention relates to an adjustable wire stay rope anchor. The anchor is composed of a first self-centering locking jig, a second self-centering locking jig, a compression spring and a plane bearing, wherein the first self-centering locking jig is provided with a connecting base, the middle part of one end of the connecting base is provided with a cylindrical boss which extends axially, the boss is internally provided with a first conical clamping jaw formed by 3-5 claws, a tension thread sleeve sleeves on the peripheral surface of the boss, the second self-centering locking jig is provided with a taper sleeve, the taper sleeve is internally provided with a second conical clamping jaw formed by 3-5 claws, and a hollow bolt sequentially along the axis, the second self-centering locking jig is positioned outside the head of the tension thread sleeve, the plane bearing is positioned between the tension thread sleeve and the taper sleeve, and the compression spring is arranged in the inner hole in the tension thread sleeve. According to the anchor, not only can wire stay ropes be prevented from loosening, but also the tension of the wire stay ropes can be fine-tuned.

Description

technical field [0001] The invention relates to a structural component of a building, in particular to an anchoring device for a steel cable. Background technique [0002] Anchors are common components at both ends of steel wire cables, and their basic structure consists of anchor rings (including single anchor rings and group anchor rings) and matching tapered clips. In order to prevent the tapered clip from loosening, the utility model patent application with the authorized notification number CN211543Y has made the following improvements: a parallel pressure plate is added on the end face of the anchor plate (equivalent to the anchor ring), and a hollow hole is pierced on the pressure plate. Bolt, the rear end (that is, the end with a larger diameter) of the tapered clip is tightened by the hollow bolt, thereby realizing the purpose of preventing the tapered clip from loosening. The utility model patent application whose authorization notification number is CN204174840U ...

AI Technical Summary

Problems solved by technology

Although the scheme described in the above-mentioned patent application can lock the tapered clips to avoid loosening of the tapered clips, if the tension of a certain steel cable is insufficient, the overall performance of the steel cable will be reduced.

To make up the tension of the steel wire cable, not only large-scale pulling equipment (such as hoist) must be used, but also there are difficulties in connecting with the pulling equipment.

[0003] The invention patent application with the publication number CN102926507A discloses an inner extruded cable anchorage. The embodiment of the patent application is combined with the attached Figure 2-5 It can be seen that although the solution disclosed in this patent application is an integrally extruded steel strand anchorage, its anti-loosening principle is still the same as that of the above-mentioned utility model patent, that is, the anti-loosening screw plug (which has the same function as the hollow bolt) is used to push Squeeze the anchor cup (also equivalent to the anchor ring) to clamp the steel strand), so this invention patent application also has the same shortcomings as the above-mentioned utility model patent
