Steel wire mesh fiber cloth reinforced pier column structure externally covered with concrete with ultra-high-performance

Abstract

The invention belongs to the technical field of civil engineering, and particularly relates to a steel wire mesh fiber cloth reinforced pier column structure externally covered with concrete with ultra-high-performance. The steel wire mesh fiber cloth reinforced pier column structure externally covered with concrete with ultra-high-performance comprises a reinforced pier column body, a FRP cloth,a steel wire mesh layer and an ultra-high performance concrete layer, wherein the FRP cloth, the steel wire mesh layer and the ultra-high performance concrete layer are arranged on the outer surface of the reinforcement pier column body from the inside out. The steel wire mesh fiber cloth reinforced pier column structure integrates the advantages of high tensile strength of fiber reinforced composite materials, can improve the brittle failure mode of FRP, and overcomes the disadvantages of slowing FRP aging and adhesive property of FRP binder prone to being affected by severe environment, thereinforced structure has the advantages of high yield load, large capacity reserve, good ductility, superior anti-seismic performance, improved durability of the structure and the like; and the steelwire mesh fiber cloth reinforced pier column structure is convenient and fast in construction, reinforcement effect is steady and obvious, and the interference of environmental factors is small.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a variety of composite material reinforcement technologies, in particular to a steel wire mesh fiber cloth-covered ultra-high performance concrete reinforced pier column structure. Background technique [0002] Civil engineering construction in developed countries generally goes through three stages: the stage of large-scale new construction, the stage of simultaneous construction and maintenance and reinforcement, and the stage of repair, reinforcement, and transformation of old structures. The U.S. Department of Labor predicted in an industry forecast report at the end of the 20th century that the structural maintenance and reinforcement industry would be one of the most popular industries in the 21st century. How to maintain, transform and strengthen the existing engineering structure has become a very important topic in the foreign civil engineering indu...
