Embodiment Construction
[0024] The present invention is described in conjunction with accompanying drawing and specific embodiment:
[0025] Such as Figure 1~4 As shown, a carbon fiber plate anchor with a self-clamping functional structure, the carbon fiber plate anchor 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 it has 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 clip The contact surface of the sheet is coated with lubricating oil or grease to reduce the friction between the anchor body and the contact surface of 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 plate is formed between the clips; the carbon fiber plate 4 is located between the two clips 2; t...

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 plate anchor with a self-clamping functional structure. Background technique [0002] Due to its high tensile strength, carbon fiber plates are used as an important material for prestressed reinforcement of bridges and buildings, and more and more people pay more and more attention to them. As early as the 1980s, many researchers conducted a series of studies on carbon fiber plate anchoring fixtures. , most of the anchors are clamped by two flat plates or flat plates with corresponding corrugated surfaces, and the carbon fiber plate is clamped by the bolt pressing force. At present, in actual engineering applications, in addition to imported SikCar non-metallic anchors, domestic carbon fiber plate anchors mainly use two flat-plate clamping anchors or flat-plate clamping anchors with corresponding corrugated surfaces. To...
