Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of anchor installation, and particularly relates to an anchor clip fixing device. Background Technique
[0002] With the increasing expansion of the construction scale, there are more and more various bridges such as highway bridges, railway bridges, sidewalk bridges, overpasses, ramp bridges, and skybridges. The prestressed tensioning technology has also been widely applied. Installing clips is an indispensable process in prestressed tensioning construction. The traditional method is to insert the clip units into the anchor plate holes respectively and then use a hammer to drive them in appropriately. However, due to the influence of the remaining steel strands, it is difficult to exert force, it is not easy to accurately hit the clip, the operator is prone to be injured, and the construction speed is relatively slow. Content of the Utility Model
[0003] The utility model aims to solve the problems such as difficult operation and slow construction in the traditional clip loading method during prestressed tensioning construction in bridge engineering.
[0004] The utility model provides the following technical solution: an anchor clip fixing device, including an inner insertion tube and an outer sleeve tube; the inner hole of the inner insertion tube serves as a steel strand insertion hole, the inner insertion tube can be sleeved on the steel strand, and the tube orifice of the inner insertion tube abuts against the large-end end face of the clip; the outer sleeve tube is slidably sleeved outside the inner insertion tube, and a limiting block for blocking the outer sleeve tube is fixed on the inner insertion tube, and the outer sleeve tube reciprocally slides to strike the limiting block so that the inner insertion tube applies a thrust force to the clip.
[0005] Further, two positioning rings coaxial with it are fixed on the outer wall of the inner insertion tube, and the inner hole of the outer sleeve tube is slidably matched with the two positioning rings.
[0006] Further, a plurality of limiting blocks are evenly distributed around the inner insertion tube.
[0007] Further, the inner insertion tube and the outer sleeve tube are circular tubes.
[0008] Compared with the prior art, the advantages of the utility model are as follows:
[0009] The anchor clip fixing device provided by the utility model is not affected by the remaining steel strands and can accurately hit the clip, greatly improving the construction efficiency; compared with the traditional anchor clip loading method, it is simple to operate, less affected by the environment, has high safety, and fast construction speed.

[0014] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.
[0015] As shown in Figure 1 、 Figure 2 A fixing device for an anchor clip includes an inner insertion tube 1 and an outer sleeve tube 2; the inner hole of the inner insertion tube 1 serves as a steel strand insertion hole, the inner diameter of the inner insertion tube 1 is slightly larger than the diameter of the steel strand and smaller than the outer diameter of the large end of the clip 4. The inner insertion tube 1 can be sleeved on the steel strand 3, and the tube opening of the inner insertion tube 1 abuts against the end face of the large end of the clip 4. The outer sleeve tube 2 is slidably sleeved outside the inner insertion tube 1. A limit block for blocking the outer sleeve tube 2 is fixed on the inner insertion tube 1. The outer sleeve tube 2 reciprocates and slides to strike the limit block 5, so that the inner insertion tube 1 applies a thrust force to the clip 4.
[0016] Two coaxial positioning rings 6 are fixed on the outer wall of the inner insertion tube 1. The inner hole of the outer sleeve tube 2 is in sliding fit with the two positioning rings 6. The sliding contact between the outer sleeve tube 2 and the positioning rings 6 reduces the resistance when the outer sleeve tube 2 slides.
[0017] The limit block 5 is a rectangular block, and several limit blocks 5 are evenly distributed around the inner insertion tube 1 for one week.
[0018] The inner insertion tube 1 and the outer sleeve tube 2 are round steel tubes, and the limit block 5 and the positioning ring 6 are welded on the inner insertion tube 1.
[0019] As shown in Figure 3 The inner insertion tube 1 is sleeved on the corresponding steel strand, the tube opening of the inner insertion tube 1 abuts against the large end of the clip 4. When the outer sleeve tube 2 reciprocates and slides, it hits the limit block 5 and stops suddenly. The potential energy of the outer sleeve tube 2 is transmitted to the inner insertion tube 1 through the limit block 5, and the inner insertion tube 1 pushes the clip 4 to move into the hole of the anchor backing plate 7. When the outer sleeve tube 2 slides, it is not interfered by other steel strands, and the potential energy of each slide of the outer sleeve tube 2 can be accurately transmitted to the target clip.
[0020] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
