Problems solved by technology
[0002] FRP cloth has the advantages of light weight and high strength, good corrosion resistance and fatigue resistance, but when fixing FRP cloth to structural concrete, the strength of the traditional fixing method is insufficient, and the utilization rate of FRP strength is low
Due to the above shortcomings, it is difficult for FRP reinforcement to be widely used in practical engineering.
[0003] At present, FRP cloth is mainly anchored by FRP bead. By pasting FRP bead perpendicular to the stressed FRP cloth, the bonding area between FRP cloth and concrete is increased. This anchoring method requires a large amount of FRP bead, and the final main failure mode of FRP cloth For the peeling and damage of FRP cloth and FRP bead, resulting in a lot of material waste

The invention discloses an anchoring structure system of an FRP (fiber reinforce plastic) fabric and structural concrete and a construction method of the system. The anchoring structure system comprises the structural concrete, two pairs of blind holes are formed in the structural concrete, bolts are arranged in the blind holes, heads of the bolts are positioned in the blind holes, gaps among theblind holes and the bolts are filled with chemical binding agents, a first FRP fabric matching resin layer is arranged on the structural concrete, a first FRP fabric layer is arranged on the first FRPfabric matching resin layer, a second FRP fabric matching resin layer is arranged on the left of the first FRP fabric layer, a second FRP fabric layer is arranged on the upper left of the second FRPfabric matching resin layer, a trapezoidal steel plate is arranged on the upper right of the second FRP fabric matching resin layer, penetrates the bolts and is fixed by nuts, and a gap between the trapezoidal steel plate and the second FRP fabric layer is filled with a third FRP fabric matching resin layer. The anchoring structure system is reasonable in structure and high in anchoring force, stripping damage between an FRP fabric and the structural concrete can be effectively prevented, the utilization rate of materials is increased, and construction cost is saved.
Description
technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an anchoring structure system of FRP cloth and structural concrete and a construction method thereof. Background technique [0002] FRP cloth has the advantages of light weight and high strength, good corrosion resistance and fatigue resistance. However, when FRP cloth is fixed to structural concrete, the strength of the traditional fixing method is insufficient, and the utilization rate of FRP strength is low. Due to the above shortcomings, it is difficult for FRP reinforcement to be widely used in practical engineering. [0003] At present, FRP cloth is mainly anchored by FRP bead. By pasting FRP bead perpendicular to the stressed FRP cloth, the bonding area between FRP cloth and concrete is increased. This anchoring method requires a large amount of FRP bead, and the final main failure mode of FRP cloth Because of the peeling and damage of FRP cloth ...
