Abstract

The invention discloses an FRP rib material with reserved bending points and a manufacturing method. A corrugated pipe is adopted, the interior of the corrugated pipe is reinforced, the defect that an existing FRP rib cannot be bent is overcome, and meanwhile the durability problem caused by corrosion of a steel elbow at the bending position of the FRP rib is solved; and a unified material can be used, the strength of the FRP composite material rib can be better exerted, the simulated result is closer to the experiment result, and the experiment result is more accurate.

Description

technical field [0001] The invention belongs to the field of FRP reinforcements, and in particular relates to an FRP reinforcement with reserved bending points and a manufacturing method. Background technique [0002] FRP bar is a kind of fiber reinforced plastic bar made of continuous fiber through pultrusion process and synthetic resin base according to a certain proportion. FRP bars have excellent properties such as high tensile strength, good corrosion resistance, light weight, excellent fatigue resistance, and good electromagnetic insulation, and are widely used in civil engineering and water conservancy projects, especially in coastal areas, port projects, large-span It is more widely used in bridge engineering and reinforcement engineering. [0003] FRP steel bar is a new type of composite material. Using it to replace steel bars in concrete structures can solve the durability problem caused by steel bar corrosion. However, FRP bars cannot be bent like ordinary stee...
