BUCKLING RESTRAINT BRACE AND MANUFACTURING METHOD THEREOF

KURATA TAKASHI

To reassure efficiency in compressive strength at a buckling restraint brace using wooden material.SOLUTION: A buckling restraint brace 10 comprises a plate-like steel core material 20, a wooden first restraint material 31 arranged at a first side of a plate thickness direction X of the core material 20 to the core material 20 and in close contact with the core material 20, a wooden second restraint material 32 arranged at a second side of the plate thickness direction to the core material 20 and in close contact with the core material 20, a first spacer 41 arranged at a first side of a plate width direction Z of the core material 20 to the core material 20 and arranged between the first restraint material 31 and the second restraint material 32 and having a thickness equal to or less than a thickness of the core material 20 and a second spacer 42 arranged at a second side of the plate width direction Z to the core material 20 and arranged between the first restraint material 31 and the second restraint material 32 and having the thickness equal to or less than the thickness of the core material 20.SELECTED DRAWING: Figure 4

【課題】木材を用いた座屈拘束ブレースにおいて、圧縮耐力についての性能を確保する。【解決手段】座屈拘束ブレース１０は、板状の鋼製の芯材２０と、芯材２０に対して、芯材２０の板厚方向Ｘの第１側に配置され芯材２０に密接する木製の第１拘束材３１と、芯材２０に対して、板厚方向Ｘの第２側に配置され芯材２０に密接する木製の第２拘束材３２と、芯材２０に対して、芯材２０の板幅方向Ｚの第１側で、かつ、第１拘束材３１と第２拘束材３２との間に配置され、厚さが芯材２０の厚さ以下である第１スペーサー４１と、芯材２０に対して、板幅方向Ｚの第２側で、かつ、第１拘束材３１と第２拘束材３２との間に配置され、厚さが芯材２０の厚さ以下である第２スペーサー４２と、を備えている。【選択図】図４
