Problems solved by technology
The construction of the direct anchoring method is relatively simple, but if the anchor rod is cracked, the steel strand is susceptible to corrosion, and its durability often fails to meet the requirements; grooves are arranged on the periphery of the U-shaped block, and a certain pre-tightening force is added to the steel strand Wrapped in the groove, the anchorage of this structure will lose 30-40% of the preload force of the steel strand, and the use effect is not good

The invention discloses a single-hole anchor and its use method, comprising an anchor body, a clip assembly, and a locking device for the clip assembly; a conical hole is arranged in the anchor body; the clip assembly consists of multiple pieces A conical shape surrounded by clips, the center of the clip assembly is provided with a first through hole; the clip assembly is arranged in the conical hole; the clip assembly locking device is used to lock the clip assembly on the anchor In the main body; the single-hole anchorage of the present invention and its use method; the anchorage body is provided with a conical hole, and a clip assembly matched with the conical hole is provided at the same time, the steel strand is arranged in the single-hole anchorage, and the clamping The clip assembly is set in the conical hole to fix the steel strand, and the clip assembly locking device is fixed on the anchor body to prevent the clip from loosening or disengaging; the single-hole anchor of the present invention has a simple structure and can be easily realized in the anchor The anchoring of the steel strand is completed in the hole.
Description
technical field [0001] The invention relates to an anchorage and its use method, in particular to a single-hole anchorage with simple structure and practicality and its use method, and belongs to the technical field of infrastructure construction tools. Background technique [0002] With the advancement of urbanization, more and more basement anti-floating projects have been produced in the construction of underground facilities such as underground parking lots, underground pedestrian passages, underground commercial streets, and underground railways. Conventional anti-floating projects usually use concrete pouring piles, prefabricated piles or anti-floating anchors, among which anti-floating anchors have the advantages of fast construction speed and high economy. [0003] The steel strands used in conventional anti-floating anchor rods have always been directly anchored in anchor holes or anchored by U-shaped blocks. The construction of the direct anchoring method is relat...
