An earthquake-proofing reinforcing metal fitting (1) of which earthquake- proofing performance is more increased than before so that a wooden building is not collapsed even if a strong vibration is applied to it by an earthquake or a typhoon, comprising an L-shaped base material (2) formed by bending a plate material and forming inwardly curved extended parts (5a, 5b) at the intermediate parts of both piece parts (2a, 2b), a reinforcing member (3) formed by bending a plate material and brought into contact with the bent part of the L-shaped base material (2), and a damping member (4) made of a rubber material excellent in elastic characteristics and water-resistance and locked to the L-shaped base material (2) at a plurality of positions, wherein, when the reinforcing member (3) is brought into contact with the L-shaped base material (2), a clearance (10) is produced between a bent corner part (3c) of the reinforcing member (3) and the bent corner part (2c) of the L-shaped base material (2).

La présente invention concerne un raccord métallique (1) de renforcement parasismique à performances parasismiques améliorées permettant à un bâtiment en bois de résister à un tremblement de terre ou à un typhon même s'il est exposé à de fortes vibrations. Ce raccord est constitué d'un matériau de base en L (2) obtenu en repliant un matériau plat et en formant des parties étendues (5a, 5b) courbées vers l'intérieur au niveau des parties intermédiaires des deux pièces (2a, 2b), un élément de renforcement (3) formé en repliant un matériau plat et mis en contact avec la partie repliée du matériau de base en L (2), et un élément amortisseur (4) en caoutchouc caractérisé par d'excellentes propriétés élastiques et de résistance à l'eau, et verrouillé au matériau de base en L (2) dans plusieurs positions. L'élément de renforcement (3) est mis en contact avec le matériau de base en L (2), un écartement étant réalisé entre un coin replié (3c) de l'élément de renforcement (3) et le coin replié (2c) du matériau de base en L (2).
