Embodiment 1

[0032] Such as Figure 1 to Figure 5 As shown, a carbon fiber cable connector for a cable-stayed bridge includes: a connector steel body (1), a harness sheath (2) coated on the outer periphery of the connector steel body (1), and the connector A plurality of frustoconical holes (3) of equal size are arranged inside the steel body (1), and wedge-shaped wire clamps (5) are installed in the frustoconical holes (3) through hollow bolts (4).

[0033] The above-mentioned carbon fiber cable connector for the cable-stayed bridge, the truncated conical hole (3) inside the connector steel body (1), except the truncated conical hole (3) coaxial with the connector steel body (1) ), the axes of the remaining frustoconical holes (3) form an angle of 5 to 10 degrees with the central axis of the connector steel body (1), and the distance between each adjacent frustoconical holes (3) is equal .

[0034] In the above-mentioned carbon fiber cable connector for a cable-stayed bridge, the includ...

Embodiment 2

[0036] 1) Grind and clean both ends of the carbon fiber cable, and the length of the grinding is 1.5 times the length of the steel body of the connector;

[0037] 2) Pass one end of the carbon fiber cable (6) through the frusto-conical hole (3) inside the connector steel body (1), then pass the carbon fiber cable (6) through the center hole of the wedge clamp (5), and Install the wedge-shaped clamp (5) in the truncated-conical hole (3), and finally tighten the hollow bolt (4) on the steel body of the connector, thereby fastening the wedge-shaped clamp (5) in the truncated-conical hole (3). inside the hole (3);

[0038] 3) Pass the other end of the carbon fiber cable (6) through the truncated conical hole (3) inside the connector steel body (1), the wedge-shaped clamp (5), the hollow bolt (4), and make the truncated cone shaped hole (3), the wedge-shaped clamp (5) and the hollow bolt (4) are not tightened; then install the pre-tightening force assembly (7) at the end of the ca...

Abstract

The invention discloses a carbon fiber cable connector for a cable-stayed bridge and a mounting method of the carbon fiber cable connector. The carbon fiber cable connector comprises a connector steel body (1) and a bunch protecting sleeve (2) wrapping on the outer periphery of the connector steel body (1). A plurality of butt cone-shaped holes (3) identical in size are formed in the connector steel body (1). Wedge-shaped wire clamps (5) are arranged in the butt cone-shaped holes (3) through hollow bolts (4). The carbon fiber cable connector for the cable-stayed bridge is reasonable in structural design, light in weight, high in intensity, large in weight-pulling ratio, good in anchoring effect, high in weather resistance and corrosion resistance and long in service life. The mounting method of the carbon fiber cable connector for the cable-stayed bridge is high in maneuverability, mounting is convenient, and mounting firmness is high.

Description

technical field [0001] The invention relates to a carbon fiber prestressed structure, in particular to a carbon fiber cable connector for a cable-stayed bridge and an installation method thereof, which can cooperate with a plurality of wedge-shaped clamps to clamp carbon fiber prestressed tendons. Background technique [0002] At present, the prestressed structure is a kind of structure that is widely used and has great potential in civil engineering, transportation and water conservancy projects in my country. In the existing prestressed structure, the prestressed steel bars are affected by the use environment (such as air pollution, acid rain, etc.) This is especially true for structures (such as sea-crossing bridges, etc.). Compared with traditional prestressed steel bars, carbon fiber composite mandrels have excellent characteristics such as corrosion resistance, large draw-to-weight ratio, and non-magnetic properties. Therefore, using this new material as a substitute ...
