Example Embodiment
[0036] Example 1
[0037] This embodiment is a kind of CFRP tendon cable group anchor anchor for bridges, which are respectively installed at both ends of the CFRP tendon cable, and the CFRP tendons are anchored by the anchor. In order to facilitate understanding and description, the anchor and the corresponding CFRP ribs (the length is omitted below) are arranged vertically. As shown in the figure, the anchor includes an anchor cup 1, which has channels with upper and lower ends open. A connecting cylinder 17 and a PE protective sleeve 18 are connected below, and a nut 19 is sheathed on the anchor cup 1. One end of the CFRP rib 11 passes through the PE protective sleeve 18 and the connecting cylinder 17 in sequence from bottom to top, and then enters the anchor cup 1, and the CFRP rib 11 is anchored in the anchor cup 1.
[0038] See the concrete anchoring structure of CFRP bar 11 figure 1 , The channel of the anchor cup 1 is provided with upper and lower wire end plates 2, 3, the...
Example Embodiment
[0046] Example 2
[0047] This embodiment is a manufacturing process of CFRP tendon cable group anchors for bridges, including the following steps:
[0048] S1) Prepare anchor cup 1, nut, upper and lower wire end plates 2, 3, wire separator 4, wire vibration damping block 7, washer 8, rubber ring 9 according to the size;
[0049] S2) Clamp the anchor cup vertically on the installation platform, and cut the CFRP ribs into wires according to the length of the anchor cup and the design length of the cable, reserve a working length for the CFRP ribs, and pass the CFRP ribs into the wire to reduce vibration Block 7, drag and install the wire-dividing vibration damping block 7 and the CFRP tendon to the lower opening of the anchor cup 1, fix the position of the CFRP tendon, and install the lower wire-dividing end plate 3 from the upper port of the anchor cup;
[0050] S3) Pour the epoxy resin iron sand mixed glue from the upper mouth of the anchor cup 1 to the lower surface of the lowermost...
