Abstract

Cette invention concerne un raccord métallique de renforcement parasismique destiné à un bâtiment en bois, Ce raccord se fixe sur la partie jointive d'un élément structural de construction tel que fondation, pilier, poutre, etc. de telle sorte que le bâtiment en bois ne s'effondre pas même s'il subit à une forte secousse provoquée par un tremblement de terre ou un cyclone. Ce raccord, qui relie l'un à l'autre des éléments structuraux tridimensionnels d'entrecroisement (A), se caractérise en ce qu'il comprend un premier élément-renfort de base (1) obtenu par cintrage à 90°d'une plaque d'acier à haute résistance, fixée à l'un des éléments structuraux (A) du bâtiment, un second élément-renfort de base (2) fixé à un autre élément structural de construction (A) et disposé symétriquement par rapport au premier élément (1) via un dispositif articulé (4). Le second élément-renfort de base (2) est formé de sorte que l'élément en plaque d'acier à haute résistance est cintré à 90°, cependant qu'un élément amortisseur (3) ayant l'élasticité du caoutchouc est installé en de multiples positions. Un élément structural de construction (A) est fixé à l'autre élément structural de construction (A) par un élément amortisseur (3).
