Problems solved by technology

Moreover, during processing, for the convenience of assembly, the inclination angle of the anchor plate is usually made slightly larger than the inclination angle of the clip, so that during use, the tip of the clip is subjected to greater extrusion force, which easily damages the carbon fiber plate

Embodiment Construction

[0014] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0015] as attached figure 2 As shown, the appearance of the anchor plate 21 is a cuboid with a length of 100mm, a width of 100mm, and a height of 50mm, with a square hole in the middle, the width of the square hole is 50-70mm, the height is 20-30mm, and two extruded surface belts with a width of 50-70mm There is an inclination of 2°. The profile of clip 22 is a cuboid with a length of 100mm and an inclination angle of 2.5° on the outside.

[0016] Clamp the carbon fiber plate 23 with the clip 22 and assemble it into the anchor plate 21. After pre-tightening, the large mouth end of the anchor plate 21 is slightly deformed to form a clamping force on the squeezed surface of the clip 22. Because the inclination angl...

Abstract

The invention relates to a strand tapered anchorage for tension of a carbon fiber plate. The strand tapered anchorage comprises an anchor plate and a clamping piece, wherein the anchor plate is provided with a square hole for installing of the clamping piece, two extruded surfaces have a 1-5 degree dip angle, and the dip angle outside the clamping piece is greater than the corresponding dip angle on the anchor plate by 0.1-1 degree. Due to the inclination difference between the clamping piece and the anchor plate, after being installed in the anchor plate, the clamping piece bears uniform clamping force on the side surface, so that the problem that the carbon fiber plate breaks at the tip of the clamping piece due to stress concentration is solved, the carbon fiber plate is prevented from being damaged, and the anchoring effect of the anchorage is improved.

Description

technical field [0001] The invention relates to a clip-type anchor for tensioning a carbon fiber plate, which belongs to the technical field of carbon fiber plate reinforcement. Background technique [0002] Carbon fiber plate has the advantages of light weight and high tensile strength, so it is an ideal reinforcement material. It has excellent application prospects in the reinforcement of steel structures. [0003] To strengthen the steel structure with carbon fiber plates, it is necessary to fix both ends of the carbon fiber plates with anchors, and then fix the anchors to the steel structure, so anchors are a key technology in the reinforcement technology of carbon fiber plates. [0004] as attached figure 1 , the currently used anchor includes an anchor plate 1 and a clip 2. The inner surface of the anchor plate 1 has a certain inclination angle, and the inclination angle of the outer surface of the clip 2 is the same as the inclination angle of the outer surface of t...
