ANTISEISMIC REINFORCEMENT STRUCTURE
PROBLEM TO BE SOLVED: To provide an antiseismic reinforcement structure by which antiseismic reinforcement can be successfully performed even when a door etc. is in a reinforcement object, and a beam of an existing building is not damaged resulting from deformation of a frame body in occurrence of an earthquake.SOLUTION: This antiseismic reinforcement structure is a reinforcement member 20 which is connected to a pillar and/or beam of an existing building, which is a steel brace 20 with a frame, and comprises: a frame body 15 which is connected to the pillar and/or beam; and a brace assembly 17 provided on an inner peripheral side of the frame body. The frame body 15 has a cut-off part 15a provided by partially cutting off a beam member 14 thereof from either of right or left lower corner, and the brace assembly 17 has a first brace, a second brace, and a third brace which are connected to three corners which are not provided with the cut-off parts of four corners in the frame body, respectively.
【課題】補強対象内にドア等が存在する場合であっても、良好に耐震補強を行うことができ、しかも地震発生時に枠体の変形に起因して既存構造物の梁を損傷させることもない耐震補強構造を提供する。【解決手段】この耐震補強構造は、既存構造物の柱および／または梁に対して接続される補強部材２０であって、補強部材は枠付鉄骨ブレース２０であり、柱および／または梁に接続される枠体１５と、この枠体の内周側に設けられたブレースアセンブリ１７）を備え、枠体１５は、左右いずれかの下側角部からその梁部材１４を一部切除して設けられた切除部１５ａを有し、ブレースアセンブリ１７は、枠体における４つの角部のうち切除部が設けられていない３つの角部にそれぞれ接続する第１ブレース、第２ブレース、および第３ブレースを有することを特徴とする。【選択図】図１
