REINFORCEMENT STRUCTURE OF FERROCONCRETE
To provide a reinforcement structure of ferroconcrete capable of efficiently transmitting shear force to a structure such as a foundation and a beam formed of ferroconcrete and preventing an increase of manufacturing cost and construction cost of a joint metal, in a joint structure using a joint metal comprising a shear cotter.SOLUTION: A reinforcement structure reinforces ferroconcrete in which a plurality of main reinforcements 34 extending in a direction substantially parallel to a surface along a surface of concrete at a position entering the inside of the concrete just by a prescribed thickness dimension from the surface of the concrete forming structures 3, 23. Some of the plurality of main reinforcements 34 are formed so that a length portion between two divided end portions 34a on the length halfway is removed. Additional reinforcements 36 extending substantially parallel to the main reinforcements 34 are provided at a position with a prescribed interval from some of the main reinforcements 34 toward the inside of the concrete. Both end portions of the additional reinforcement 36 are disposed so that a position of the additional reinforcement 36 in a length direction is positioned at an opposite side to a central portion of the additional reinforcement 36 with respect to the two divided end portions 34a of some of the main reinforcements 34.SELECTED DRAWING: Figure 1
【課題】シアコッターを備えた接合金物を用いた接合構造において、せん断力を鉄筋コンクリートにより形成された基礎や梁のような構造物に効率よく伝達できると共に、接合金物の製造コストや施工コストの増加を防止できる鉄筋コンクリートの補強構造を提供する。【解決手段】構造物３，２３を形成するコンクリートの表面から所定の厚さ寸法だけコンクリートの内部側に入り込んだ位置に、コンクリートの表面に沿った表面と略平行な方向に伸びる複数の主鉄筋３４が配置されるような鉄筋コンクリートを補強する構造であって、複数の主鉄筋３４のうちの一部の主鉄筋３４は、その長さ途中の２か所の分断端部３４ａの間の長さ部分が取り除かれたように形成され、一部の主鉄筋３４からコンクリートの内部側に所定の間隔をおいた位置に、主鉄筋３４と略平行に伸びる追加鉄筋３６が設けられ、追加鉄筋３６の両端部は、その追加鉄筋３６の長さ方向の位置が、一部の主鉄筋３４の２つの分断端部３４ａより、追加鉄筋３４の中央部と反対側に位置するように配置された。【選択図】図１
