Composite CFRP (Carbon Fibre Reinforced Polymer) tendon anchoring system
The invention discloses a composite CFRP (Carbon Fibre Reinforced Polymer) tendon anchoring system which comprises an anchor ring, a two-piece wedge-shaped clip, a soft metal sheath and an epoxy adhesive film, wherein the soft metal sheath is fixed at the anchoring end of a CFRP tendon by the epoxy adhesive film so as to form an integral apparatus; and the integral apparatus is inserted in the two-piece wedge-shaped clip, and the two-piece wedge-shaped clip extends in the anchor ring and then is fixed. The composite anchorage device has the characteristics of small size, large anchoring force, and easiness for installation and use, and is applicable to the on-site construction of prestressed structures. Under the condition of not increasing the size of the anchor ring, the anchoring force can be increased in a mode of increasing the bonding length of the soft metal sheath, and the transverse force of the CFRP tendon is protected. The composite CFRP tendon anchoring system can anchor a single tendon, and also can anchor multiple tendons, thus being extremely applicable to prestressed structures.
