Abstract

The invention discloses a circular section muti-layer sheet type CFRP inhaul cable system and relates to the technical field of civil engineering and composites. The circular section muti-layer sheettype CFRP inhaul cable system comprises CFRP sheets, sheet type foam, circular-arc type foam, a polyethylene protection sleeve, an upper corrugated clamping plate, a lower corrugated clamping plate, corrugated clamping sheets, bolts, nuts and gaskets. The CFRP sheets different in width are stacked in the rule that the width dimensions of the CFRP sheets are gradually reduced from the middle to theupper and lower layers, the sheet type foam different in width is used for spacing the CFRP sheets at a free section of an inhaul cable, top points of the outer edges of all the CFRP sheets and the sheet type foam are internally connected with one circle together to form a virtual circular section, and the outer portions of the CFRP sheets and the sheet type foam are wrapped with the polyethyleneprotection sleeve. The CFRP sheets are spaced through the corrugated clamping sheets in an anchoring section and are clamped and anchored through the corrugated clamping plates. The circular sectionmuti-layer sheet type CFRP inhaul cable system overcomes the defect that a circular section stick type CFRP inhaul cable is difficult to anchor, solves the problem that a rectangular section sheet type CFRP inhaul cable is poor in wind-induced vibration resistance and can be applied to cable-stayed bridges, suspension bridges and space cable structures.

Description

technical field [0001] The invention relates to the fields of civil engineering, mechanical engineering, composite material technology and the like, and in particular relates to a CFRP cable system of circular cross-section multilayer sheet type. Background technique [0002] CFRP (Carbon Fiber Reinforced Polymer, carbon fiber reinforced plastic) is a new type of high-performance composite material, which is composed of carbon fiber and a polymer matrix wrapped with carbon fiber. CFRP has many excellent mechanical properties such as light weight, high strength, corrosion resistance, fatigue resistance, low creep, and high damping. The cables made of CFRP can solve the problems of excessive weight, insufficient strength, low load-bearing efficiency, and poor durability of steel cables. and other shortcomings. Replacing steel cables with CFRP cables in highly corrosive environments such as long-span bridges and space structures, marine and chemical plants, and fatigue-prone e...
