CFRP group anchor anchoring system
The CFRP group anchor anchoring system comprises a sleeve, one end of the sleeve is provided with a collecting cavity with the diameter gradually reduced in the length direction of the sleeve, the other end of the sleeve is provided with a straight cavity in the length direction of the sleeve, and the straight cavity and the narrow-opening end of the collecting cavity are the same in diameter and communicate with each other; and an arc-shaped surface is arranged at the joint of the collecting cavity and the straight cavity. The arc-shaped surface is arranged at the joint of the collection cavity and the straight cavity, and the cone angle of the collection cavity and the curvature radius of the arc-shaped surface are limited, so that the extrusion stress borne by the outer-layer CFRP can be greatly reduced.
本发明公开了一种CFRP群锚锚固系统，包括：套筒，所述套筒的一端沿套筒的长度方向开设有直径逐渐减小的收束腔，所述套筒的另一端沿套筒的长度方向开设有直腔，所述直腔与收束腔窄口一端直径相同并相互连通，所述收束腔与直腔的连接处设置为弧形面。通过在收束腔和直腔的连接处设置有弧形面，且通过限定收束腔的锥角以及弧形面的曲率半径，可以大大降低外层CFRP所受的挤压应力。
