Problems solved by technology
[0005] The present invention aims at the problem that the distance between the prestressed FRP slab anchorage FRP slab and the concrete base surface is too large, and the existing solutions cannot realize the reduction of the distance well, and proposes a prestressed FRP slab steering device and a steering method, which can realize FRP The smooth turning of the plate from the loading end of the anchor to the base surface of the reinforced beam has little effect on the ultimate strength of the FRP plate, and has the advantages of convenient construction and reliable performance.

Abstract
The invention discloses a prestressed FRP panel steering device and a steering method. The prestressed FRP panel steering device includes a support frame, a first steering plate and a second steering plate; the support frame includes a first support section and a second support section The inside of the first support section is provided with a first support section groove; the inside of the second support section is provided with a second support section groove; the first turning plate is arranged in the first support section groove; The second diversion plate is arranged in the groove of the second support section; the upper surface of the first diversion plate is the guide surface of the prestressed FRP plate; the lower surface of the second diversion plate is the guide surface of the prestressed FRP plate The guide surface is an FRP plate channel below the guide surface of the second turning plate. A prestressed FRP panel steering device disclosed by the present invention can realize reliable steering of the FRP panel, make the FRP panel close to the base surface of the reinforced beam, reduce the distance between the FRP panel and the base surface of the reinforced beam, and not only reduce the amount of glue used , cost saving, can also reduce the shear stress of the adhesive layer, and ensure good interface performance.
Description
technical field [0001] The invention relates to a prestressed FRP board steering device, which belongs to the field of civil engineering structure reinforcement or reinforcement. Background technique [0002] FRP board is a rigid sheet prepared by impregnating fiber materials with resin and then pultruded. It has the advantages of light weight, high strength and corrosion resistance, and is often used in the field of engineering reinforcement. The prestressed FRP plate external reinforcement technology applies the prestressed FRP plate to the tensile side of the concrete structure to be reinforced with an adhesive such as epoxy resin, which can effectively improve the performance of the structure during use, and give full play to the material properties of concrete and FRP. It has the advantages of anti-stripping damage and fatigue resistance, so it has been widely used in structural reinforcement such as bridges. [0003] In order to prevent the peeling of the FRP plate an...
