Clamping piece installation accessory

Abstract

The invention belongs to the technical field of engineering construction, and particularly relates to a clamping piece installation accessory. The clamping piece installation accessory comprises a tube base with separation pieces symmetrically arranged in the circumferential direction, the tube base and the separation pieces form limiting displacement fit in the tube length direction of the tube base, the separation pieces move between an overhanging position extending out of the tube end of the tube base and a retracting position retracting into the tube base, and the sectional dimensions ofthe separation pieces along the circumferential direction of the tube base are the same. When the separation pieces are located at the overhanging position, the separation pieces are matched with clamping pieces, the minimum distance of the clamping pieces can be guaranteed, and after the clamping pieces are preliminarily positioned, the separation pieces are driven to move to the retracting position, and then subsequent anchoring operation can be completed. The clamping piece installation accessory is easy to operate, the clamping pieces are convenient to position, and the reliability of an anchoring system can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, in particular to a clip installation auxiliary part. Background technique [0002] In the clip-type prestressed anchoring system, the internal wire teeth of the clip are engaged with the surface of the steel strand, and the outside of the clip is matched with the tapered hole of the anchorage. The steel strand is stretched so that the clip moves along with the steel strand toward the tapered hole. The displacement of the small diameter end realizes the anchoring of the steel strand. In the prior art, for an anchoring structure using three-lobed clips matched with steel strands, gaps are reserved between adjacent clips. The smaller the gap, the greater the bite force between the clips on both sides and the steel strand, and the deeper the bite marks. During construction, it is difficult to manually position the clips to ensure that the clips are evenly spaced, resulting in uneve...

AI Technical Summary

Problems solved by technology

During construction, it is difficult to manually position the clips to ensure that the clips are evenly spaced, resulting in uneven bite between the circumference of the steel strand and the clips. If the gap between the clips is too small and the bite marks are too deep, the steel strand may be damaged early, resulting in Anchorage failure
