Clamping piece type CFRP rib clamping anchorage device
The invention discloses a clamping piece type CFRP rib clamping anchorage device which comprises a metal shell, a pre-tightening pressure plate, wedge-shaped clamping pieces, a soft metal protecting jacket, a sealing plate and a spring. The wedge-shaped clamping pieces are arranged in the metal shell. A CFRP rib sleeved with the soft metal protecting jacket penetrates into the wedge-shaped clamping pieces. The pre-tightening pressure plate is sleeved with the spring, presses the wedge-shaped clamping pieces down and is used for exerting pre-tightening force on the CFRP rib. The sealing plate penetrates into the metal shell to be fixed. The clamping piece type CFRP rib clamping anchorage device has larger clamping force, and can effectively anchor the transverse enhancement CFRP rib. Inner teeth of the clamping pieces can bite the soft metal protecting jacket so as to reduce slipping in the anchorage device; the soft metal protecting jacket can effectively protect the CFRP rib, and the clamping force of the clamping pieces is reduced; the sealing plate can have the effect of fixing the wedge-shaped clamping pieces to prevent the clamping pieces from slipping out of the metal shell.
