BUCKLING RESTRAINING BRACE
To provide a buckling restraining brace that is suitable for use by being incorporated in a frame of a wooden building or the like, and, for example, at the time of a large earthquake, prevents the frame and the buckling restraining brace from deforming to the outside of a structure plane, a core material forming the buckling restraining brace from pressing a restraining plate forming a wooden restraining material, and a side plate pulled by the restraining plate from cracking.SOLUTION: A buckling restraining brace includes: a core material 10 formed of steel and having a plate shape; and a wooden restraining material 20 formed by a pair of wooden restraining plates 21 arranged so as to face two wide surfaces 11a included in the core material 10 and a pair of wooden side plates 22 arranged so as to face two narrow surfaces 11b included in the core material 10 and connected to the pair of restraining plates 21. The side plates 22 and the restraining plates 21 have an axial length shorter than that of the core material 10. The wooden restraining material 20 is provided with, in an end thereof, a pair of first steel materials 30A that are arranged outside of the pair of restraining plates 21 and tightened to each other with a bolt to restrain the pair of restraining plate 21.SELECTED DRAWING: Figure 3
【課題】木造建築物等の架構内に組み込んで使用するのに好適であり、例えば大地震時に架構と座屈拘束ブレースが構面外に変形し、座屈拘束ブレースを形成する芯材が木製拘束材を形成する拘束板を押し込み、拘束板に引っ張られた側板に割れが生じることを解消できる、座屈拘束ブレースを提供すること。【解決手段】鋼製でプレート状の芯材１０と、芯材１０の有する二つの広幅面１１ａに対向するように配設されている木製で一対の拘束板２１と、芯材１０の有する二つの狭幅面１１ｂに対向するように配設され、一対の拘束板２１に接続されている木製で一対の側板２２とにより形成される木製拘束材２０とを備え、側板２２と拘束板２１は芯材１０よりも軸方向の長さが短く、木製拘束材２０の端部には、一対の拘束板２１の外側に配設されて、相互にボルト締めされることにより一対の拘束板２１を拘束する、一対の第１鋼材３０Ａが設けられている。【選択図】図３
