SEISMIC REINFORCEMENT STRUCTURE OF H-SHAPED STEEL COLUMN
PROBLEM TO BE SOLVED: To provide a seismic reinforcement structure of an H-shaped steel column which can improve seismic performance with a seismic reinforcement space as a minimum limit by a simple constitution.SOLUTION: A seismic reinforcement structure of an H-shaped steel column is composed of: the H-shaped steel column in which tie-rod insertion holes are formed with prescribed intervals in a height direction of a web 3; a form member 7 which is continuously arranged in the height direction of the H-shaped steel column, and in which engagement parts 7b engaged with flange end parts are formed at both ends of a center part which is fit between flanges 2, 2, and tie-rod insertion holes are formed in positions corresponding to the tie-rod insertion holes of the web 3; reinforcement plates 8 which are laminated at the outside of the form member 7, and in which tie-rod insertion holes are formed in positions corresponding to the tie-rod insertion holes of the web 3 and the form member 7; tie rods 9 which are inserted into the tie-rod insertion holes formed at the reinforcement plates 8, the form member 7 and the web 3, and in which male screws are formed at both ends; nuts 10 which are screwed to the both-end male screws of the tie rods 9; reinforcement bars which are arranged in a space surrounded by H-shaped steel and the form member; and a solidification material which is changed into the space surrounded by the H-shaped steel and the form member 7.SELECTED DRAWING: Figure 5
【課題】簡単な構成で耐震補強スペースを最小限として耐震性能を向上させることが可能なＨ型鋼柱の耐震補強構造を提供する。【解決手段】ウェブ３に高さ方向に所定間隔でタイロッド挿通孔を形成したＨ型鋼柱と、Ｈ型鋼柱の高さ方向に連設されフランジ２，２間に嵌入する中央部の両端にフランジ端部と係合する係合部７ｂを形成し、ウェブ３のタイロッド挿通孔と対応する位置にタイロッド挿通孔を形成した型枠部材７と、型枠部材７の外側に積層されウェブ３及び型枠部材７のタイロッド挿通孔と対応する位置にタイロッド挿通孔を形成した補強プレート８と、補強プレート８、型枠部材７、ウェブ３に形成したタイロッド挿通孔に挿入される両端に雄ネジを形成したタイロッド９と、タイロッド９の両端雄ネジに螺着されるナット１０と、Ｈ型鋼と型枠部材に囲まれた空間に配筋される補強筋と、Ｈ型鋼と型枠部材７に囲まれた空間に充填される固化材と、からなる。【選択図】図５
