Embodiment 1

[0047] Example of Mechanical Clamping Anchor for Carbon Fiber Plate

[0048] see Figure 1-2 , the embodiment of the present invention provides a carbon fiber plate mechanical clamping anchor, including an anchor unit 100 .

[0049] The anchor unit 100 is used to clamp the carbon fiber plate 200. When in use, the carbon fiber plate 200 is clamped on the two anchor units 100, and the two anchor units 100 realize the tension of the carbon fiber plate 200, and the carbon fiber plate 200 has tension. Prestressed, able to withstand external compressive stress, and then realize its function. Therefore, two anchor units 100 are provided, and each anchor unit 100 is clamped at one end of the carbon fiber plate 200 , and the two anchor units 100 are arranged opposite to each other, thereby realizing the tension of a carbon fiber plate 200 . In actual processing, the carbon fiber plate 200 is set as a rectangular plate. The rectangular plate has two opposite plate surfaces and two set...

Embodiment 2

[0061] Example of a reinforcement device

[0062] see Figure 3-6 , this embodiment provides a reinforcement device, including the carbon fiber plate mechanical clamping anchor of embodiment 1, a carbon fiber plate 200 , a jack 400 , a tension baffle 500 and two fixing devices 300 arranged in pairs.

[0063] The fixing device 300 is used to fix the anchor on the object to be reinforced. In this embodiment, the steel beam 600 is taken as an example, and the reinforcing device is used to strengthen the steel beam 600 . There are two fixing devices 300, and each fixing device 300 corresponds to one anchor unit 100, and the anchor unit 100 can slide in the corresponding fixing device 300, that is, after the two anchor units 100 fix the carbon fiber plate 200, the anchor The anchor unit 100 is installed on the corresponding fixing device 300. By adjusting the positions of the anchor unit 100 and the fixing device 300, the tension of the carbon fiber plate 200 is realized. The tens...

Abstract

The invention provides a mechanical gripping anchor for a carbon fiber plate and a reinforcing device. The anchor comprises two anchor units, which are arranged in pairs, wherein each anchor unit comprises an upper anchor block, a lower anchor block and two clamping pieces; the two clamping pieces are oppositely arranged and are located between the upper anchor block and the lower anchor block; the upper anchor block is fixedly connected with the lower anchor block through a high-strength bolt; and the reinforcing device comprises the anchor and the carbon fiber plate. The installation method of the anchor is convenient to construct and good in anchoring effect; the construction period is shortened; the construction efficiency is improved; and the carbon fiber plate is uniform in stress after being anchored by the anchor.

Description

technical field [0001] The invention relates to the technical field of structural reinforcement, in particular to a carbon fiber plate mechanical clamping anchor and a reinforcement device. Background technique [0002] Carbon fiber plate is a new type of material. Its molding process is to impregnate carbon fiber with resin, solidify it in a mold, and then continuously pultrude it. Using high-quality carbon fiber raw materials and good basic resin, the carbon fiber sheet has good properties such as high tensile strength, corrosion resistance, shock resistance, and impact resistance. In recent years, it has been widely used in the field of structural reinforcement. The common reinforcement method is to directly paste carbon fiber plates on the damaged structure for structural reinforcement. [0003] The inventor found in the research that the traditional way of using carbon fiber plates for reinforcement has at least the following problems: [0004] First, it is inconvenie...
