To provide an aseismic reinforcement structure capable of preserving an existing cantilever slab and avoiding double placement of concrete to reinforce earthquake resistance of an existing building.SOLUTION: An aseismic reinforcement structure 100 comprises a reinforcement pillar part 10 placed at a position corresponding to a pillar part 3 of an existing building 1, and a reinforcement beam part 20 placed at a position corresponding to a beam part 4 of the existing building 1. The reinforcement pillar part 10 and the reinforcement beam part 20 have an extrusion joint part 14 mutually shared at an intersection part thereof. The reinforcement beam part 20 is a wide flat beam having a rectangular cross section, the height of which is smaller than the width, and a lower edge 20a is positioned above a lower edge 4a of the beam part 4, and comes into contact with a lower surface 5a of a cantilever slab 5 to extend outwardly and horizontally. Furthermore, the extrusion joint part 14 has a hinge relocation structure having a width greater than that of the pillar part 3 and forming a hinge part H near a width end part thereof.SELECTED DRAWING: Figure 2A 【課題】既存の片持ちスラブを温存し、かつコンクリートの二度打ちを回避して、既設建物を耐震補強することができる耐震補強構造を提供する。【解決手段】耐震補強構造１００は、既設建物１の柱部３に対応する位置に配置された補強柱部１０と、既設建物１の梁部４に対応する位置に配置された補強梁部２０とを備える。補強柱部１０と補強梁部２０は、その交差部に互いに共有する張出接合部１４を有する。補強梁部２０は、矩形断面を有し、その高さが幅より小さい幅広扁平梁であり、下端２０ａが梁部４の下端４ａより上方に位置し、かつ片持ちスラブ５の下面５ａに接して外方に水平に延びる。さらに張出接合部１４は、柱部３より幅が大きく、その幅端部近傍にヒンジ部Ｈを形成するヒンジリロケーション構造を有する。【選択図】図２Ａ
