Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0027] In order to solve the technical problems in the known technology, the present invention provides a large-angle clip-type CFRP tendon clamping anchorage used in prestressed concrete structures and suspensive structures. The anchorage can effectively anchor transversely reinforced CFRP tendons, Moreover, the anchor body is small in size, easy to use, and has great versatility. See Figure 1 to Figure 5 , see the description below:

[0028] A clamping anchor for clip-type CFRP tendons, mainly used for large-angle clip-type CFRP tendons, including: metal shell 1, pre-tightened pressure plate 2, wedge-shaped clip 3, soft metal protective sleeve 4, sealing plate 5 and Spring 6.

[0029] The wedge-shaped clip 3 is arranged in the metal shell 1, and the CFRP tendon sleeved with...

Abstract

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.

Description

technical field [0001] The invention relates to the field of prestressed concrete structures and string support structures in civil engineering, in particular to a clip-type CFRP tendon clip-type anchorage. Background technique [0002] Carbon Fiber Reinforced Polymer (CFRP) has been applied to prestressed structures instead of steel cables, but CFRP tendons have weak lateral force performance and require special anchoring methods. The existing CFRP tendon clamping anchors have large volume, low clamping force, inconvenient installation and use, and poor versatility. Therefore, for the transversely reinforced CFRP tendons, a small, easy-to-use large-angle clip-type CFRP tendon clamping anchorage is designed. Contents of the invention [0003] The present invention provides a clip-type CFRP tendon clamping anchor. The purpose of the invention is to solve the anchoring problem of CFRP tendons, so that the large-angle clip-type CFRP tendons can be better applied to prestress...
