EARTHQUAKE RESISTANCE REINFORCING STRUCTURE, AND EARTHQUAKE RESISTANCE REINFORCING METHOD
To provide an earthquake resistance reinforcing structure not requiring much work during construction, efficiently reinforcing RC walls with openings, and capable of mitigating reduction in strength after reinforcement, and to provide an earthquake resistance reinforcing method using the same.SOLUTION: In an earthquake resistance reinforcing structure, a blocking portion 57 made of a second concrete 1 formed using concrete or mortar with adhesive properties is provided at an opening in an RC wall. A plurality of wall crack prevention bolts 2 are embedded in a periphery of the opening so as to be perpendicular to a non-load-bearing wall 53, and a water-absorption adjustment material is applied to a boundary surface between the opening and the blocking portion 57.SELECTED DRAWING: Figure 1
【課題】施工時の手間がかからず、開口付きのＲＣ壁を効率良く補強し、補強後の耐力低減を緩和することが可能な耐震補強構造とそれを用いた耐震補強工法を提供する。【解決手段】本発明の耐震補強構造では、ＲＣ壁の開口に、接着力を有するコンクリート又はモルタルを用いて形成された第２のコンクリート１からなる閉塞部５７が設けられており、複数本の壁割り裂け防止ボルト２が非耐力壁５３に対して直交するように開口の周辺部に埋設されるとともに、吸水調整材が開口と閉塞部５７の境界面に塗布されている。【選択図】図１
