To provide a structural reinforcement structure using reinforcement member facilitating weight reduction and precasting while ensuring rigidity and load resistance.SOLUTION: Each of a pillar 10 and a beam-column connection portion 10a are formed of a reinforcement panel 12 that includes a core material 11 in which a cross-laminated timber (CLT) of multiple wood plates which are laminated so that each layer is orthogonal to each other and cellulose nanofibers (CNF) attached to the outer peripheral surface of the core material 11 enclosing the same. A beam 20 is also constituted of a core material 21 of the CLT and a reinforcement panel 22 of the CNF attached to the outer peripheral surface of the core material 21 enclosing the same.SELECTED DRAWING: Figure 1
【課題】剛性や耐力を確保しつつ、軽量化やプレキャスト化が容易な補強部材を用いた構造体の補強構造を提供する。【解決手段】柱１０と柱梁接合部１０ａを、木の板の各層を互いに直交するように積層接着した直交集成材（ＣＬＴ）から成る芯材１１と、芯材１１の外周面を囲むように取付けられる、セルロースナノファイバー（ＣＮＦ）から成る補強板１２とから構成した。また、梁２０についても、ＣＬＴから成る芯材２１と、芯材２１の外周面を囲むように取付けられる、ＣＮＦから成る補強板２２とから構成した。【選択図】図１
