Fabricated adjustable carbon fiber reinforced plastic (CFRP) cable anchoring tool

Abstract

The invention discloses a fabricated adjustable carbon fiber reinforced plastic (CFRP) cable anchoring tool and belongs to the technical field of bridge engineering. According to the fabricated adjustable CFRP cable anchoring tool, later stage cable adjustment is convenient, internal stress is reasonable, and repeated use is available. The fabricated adjustable CFRP cable anchoring tool comprises a steel sleeve and an anchoring nut, and is characterized in that a first annular rib is arranged inside one end of the steel sleeve, a thread is arranged on the outer side of the other end of the steel sleeve, and the thread is matched with the anchoring nut; a steel barrel is arranged inside one side of the first annular rib of the steel sleeve, a rib steel barrel is arranged inside the other side of the first annular rib of the steel sleeve, a second annular rib is arranged in the middle of the inner side of the rib steel barrel, a wedge-shaped clamping piece penetrates through the second annular rib of the rib steel barrel to be arranged in the rib steel barrel, an anchoring ring is arranged between the outer end of the wedge-shaped clamping piece and the rib steel barrel, and the inner end of the wedge-shaped clamping piece is connected with the inner end of the steel barrel; and a first spring is arranged outside the portion, located between the second annular rib of the rib steel barrel and the steel barrel, of the wedge-shaped clamping piece, a second spring is arranged outside the portion, located between the rib steel barrel and the first annular rib of the steel sleeve, of the steel barrel, and the outer end of the rib steel barrel makes contact with the anchoring nut.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, in particular to an assembled adjustable CFRP cable anchor. Background technique [0002] Carbon Fiber Reinforced Plastic (CFRP) has excellent properties such as high strength, low density, fatigue resistance and corrosion resistance, and has been widely researched and applied in civil engineering instead of steel cables. The existing CFRP cable anchors are basically three types: bonding type, clip type and composite type. After the CFRP cable is anchored and the structure is put into use, when the CFRP cable shrinks, relaxes, or needs to continue to stretch due to the load-bearing requirements of the structure, the existing anchorage is inconvenient to adjust the cable in the later stage, the clamping force is low, and the anchorage cannot be reused. . Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides an assembled a...
