Embodiment Construction

[0023] The present invention will be described with reference to the drawings and specific embodiments:

[0024] Such as Figure 1~4 As shown, a carbon fiber board anchor with a self-clamping function structure includes an anchor body 1 and a clip 2; the center of the anchor body 1 has an axial through hole, and the center of the anchor body The axial through hole is a wedge-shaped hole; the clip 2 is located in the axial through hole of the anchor body 1, and the clip 2 is two arranged up and down, and the anchor body and the clip The contact surface of the sheet is coated with lubricating oil or grease to reduce the friction between the contact surface of the anchor body and the clip; the outer surface of the clip 2 is a wedge-shaped surface that matches the axial through hole of the anchor body; two A cavity for clamping the carbon fiber board is formed between the clips; the carbon fiber board 4 is located between the two clips 2; the carbon fiber board 4 and the two clips 2...

Abstract

The invention belongs to the technical field of bridge engineering and building engineering, and provides an anchor with automatic clamping functional structures and a carbon fiber plate. The anchor with the automatic clamping functional structures and the carbon fiber plate comprises an anchor body (1) and two clamp sheets (2). The carbon fiber plate (4) is positioned between the two clamp sheets (2); transition base plates (3) are arranged between the carbon fiber plate (4) and the two clamp sheets (2) and are integrally adhered with the carbon fiber plate (4); the carbon fiber plate (4) is clamped by the two clamp sheets (2) via the transition base plates (3), and certain clamping force can be exerted on the carbon fiber plate (4) by the clamp sheets (2); grooves are formed in the inner surfaces of the clamp sheets (2), so that automatic clamping effects can be realized by the anchor when the carbon fiber plate (4) is tensioned, and the carbon fiber plate can be effectively clamped and keeps being self-locked. The anchor has the advantages of convenience in operation and reliability in force transfer. Besides, anchoring and tensioning effects can be realized for the high-stress carbon fiber plate.

Description

Technical field [0001] The invention belongs to the technical field of bridge engineering and construction engineering, and mainly relates to a carbon fiber board anchor with a self-clamping function structure. Background technique [0002] Because of its high tensile strength, carbon fiber board is used as an important material for prestressed reinforcement of bridges and buildings, and it has attracted more and more attention. As early as the 1980s, many researchers conducted a series of research on carbon fiber board anchoring fixtures. Most of the anchors are clamped by two flat plates or flat plates with corresponding wavy surfaces, and the carbon fiber plates are clamped by bolt compression force. At present, in actual engineering applications, in addition to imported SikCar non-metallic anchors for carbon fiber board anchors, domestic carbon fiber board anchors mainly use two flat-plate clamping anchors or flat-plate clamping anchors with corresponding wavy surfaces. With...
