BRACE EARTHQUAKE RESISTANCE REINFORCEMENT STRUCTURE OF EXISTING BUILDING AND EARTHQUAKE RESISTANCE REINFORCEMENT METHOD
PROBLEM TO BE SOLVED: To provide a brace earthquake resistance reinforcement structure of an existing building and an earthquake resistance reinforcement method, capable of reducing a steel material use quantity, excellent in workability, and capable of reinforcing with high construction efficiency.SOLUTION: A brace earthquake resistance reinforcement structure comprises a steel frame beam 20 installed along an existing beam 40 and a brace having one end joined to the steel frame beam 20. The steel frame beam 20 is a cross-sectional shape of having a recess-shaped part 20a capable of filling grout 16, and has a post-construction anchor insertion loose hole 11 in a plurality of places in the longitudinal direction of a web part 20b for forming its bottom surface, and has a female screw part 12 positioned on both sides in the width direction of the web part to the loose hole 11, in a plurality of places in the longitudinal direction. A plurality of post-construction anchors 10 installed on the existing beam 40 are inserted into the respective loose holes 11, and are fastened to the web part 20b by a nut 14. A strut bolt 15 is screwed in the respective female screw parts 12, and its tip is pushed against the existing beam 40. The grout 16 is filled and hardened over the existing beam 40 from the recess-shaped part 20a of the steel frame beam 20.SELECTED DRAWING: Figure 2
【課題】 鋼材使用量を削減でき、施工性が良く高い施工精度で補強できる既存建物のブレース耐震補強構造および耐震補強方法を提供する。【解決手段】 既存梁４０に沿って設置された鉄骨梁２０と、この鉄骨梁２０に一端が接合されるブレースを備える。鉄骨梁２０は、グラウト１６を充填可能な凹み形状部分２０ａを有する断面形状で、その底面を成すウェブ部２０ｂの長手方向複数箇所に後施工アンカー挿通用のルーズ孔１１を有する。ルーズ孔１１に対してウェブ部の幅方向の両側に位置する雌ねじ部１２を、長手方向複数箇所に有する。既存梁４０に設置された複数本の後施工アンカー１０が各ルーズ孔１１に挿通されて前記ウェブ部２０ｂにナット１４で止め付けられる。各雌ねじ部１２に突っ張り用ボルト１５がねじ込まれてその先端が既存梁４０に押し当てられる。鉄骨梁２０の凹み形状部分２０ａから既存梁４０に渡りグラウト１６が充填され硬化される。【選択図】 図２
