Description
【０００１】[0001]
この考案は鉄筋に変るコンクリート補強材ＦＲＰの表面化工に関するもので ある。 The present invention relates to the surface modification of a concrete reinforcing material FRP that changes into a reinforcing bar.
【０００２】[0002]
（１） 従来ＦＲＰのコンクリート補強材は表面に硅砂を附着させてコンクリー トとの離脱を防ぐ方法と （２） 繊維を組紐状に編んだ後樹脂を含侵硬化させ、表面が組紐の凹凸でコン クリートとの脱離を防ぐ形状のＦＲＰ補強材であった。 (1) The conventional FRP concrete reinforcing material has a method of attaching silica sand to the surface to prevent separation from the concrete, and (2) Knitting fibers into a braid shape and then impregnating and curing the resin so that the surface has unevenness of the braid. The FRP reinforcing material had a shape that prevents the concrete from coming off.
【０００３】[0003]
従来のコンクリート補強材のＦＲＰには次の様な欠点があった。 （１） ＦＲＰコンクリート補強材の表面に硅砂を附着させ、コンクリートとの 離脱を防ぐ方法は硅砂の粒子が大きいと補強材の表面から剥離し易く、又粒子が 小さいとコンクリートとの摩擦が小さくコンクリートから脱離する危険があった 。 （２）又組紐状のＦＲＰ補強材は繊維をＦＲＰに樹脂加工する時、組紐状である ので組紐繊維の内部への樹脂の含侵が時間がかかり、又不充分である為に充分な 強度が得られない。 The conventional concrete reinforcing material FRP has the following drawbacks. (1) The method of attaching silica sand to the surface of the FRP concrete reinforcement to prevent it from coming off from the concrete is that if the silica sand particles are large, they are easily separated from the surface of the reinforcement, and if the particles are small, the friction with concrete is small. There was a danger of getting out of the car. (2) In addition, since braided FRP reinforcing material is braided when the resin is processed into FRP, it takes time for the resin to infiltrate the inside of the braided fiber, and the braided fiber has sufficient strength.

本考案は一方向に平行に並んだ繊維束とエポキシ樹脂からなるコンポシエト の構造体（ＦＲＰ）の表面に樹脂を含侵した繊維の収束をらせん状に連続して巻 く事により、ＦＲＰコンクリート補強材の表面に凹凸を作りコンクリートとの摩 擦を大きくし脱離を防ぎ、又補強材本体の強度も向上する考案である。 The present invention is a FRP concrete reinforced by winding spirally a bundle of resin-impregnated fibers on the surface of a composite structure (FRP) consisting of a fiber bundle and epoxy resin arranged in parallel in one direction. The idea is to create irregularities on the surface of the material to increase the friction with the concrete to prevent detachment and to improve the strength of the reinforcing material body.
【０００５】[0005]
【作用】 ＦＲＰの表面のらせん状の凸部がコンクリートとの密着を良くし脱離を防ぐ効 果を大にしてコンクリート構造体全体をより強化する作用がある。[Function] The spiral protrusions on the surface of the FRP have the effect of improving the close contact with concrete and preventing detachment, and further strengthening the entire concrete structure.
【０００６】[0006]
以下、本案の実施例について説明する。 （イ） 一方向に並んだ繊維束に樹脂を含侵させた棒状構造物（ＦＲＰ）（１） の表面に樹脂を侵食させた繊維の収束 （２）をらせん状に巻き一体硬化させ、 棒状構造物の表面にらせん状の凸部を附けコンクリートとの脱離を防ぐ。 Hereinafter, examples of the present invention will be described. (A) Rod-like structure (FRP) (1) in which resin is impregnated into fiber bundles arranged in one direction. Convergence of resin-infiltrated fibers (2) is spirally wound and integrally cured, A spiral projection is attached to the surface of the structure to prevent detachment from the concrete.
