Abstract

Le procédé d'assemblage de poutres selon un premier mode de réalisation de la présente invention comprend: une étape d'assemblage pour assembler une poutre en acier en forme de H s'étendant dans la direction horizontale, à un élément de structure à une position au-dessus d'un espace dans un état dans lequel l'espace est généré, dans la direction horizontale, entre une bride inférieure de la poutre et l'élément de structure; une étape de fixation pour insérer, dans l'espace, un premier élément de coin ayant une première surface inclinée obliquement vers le haut, qui fait face horizontalement à l'élément de structure, et fixer le premier élément de coin à la bride inférieure; et une étape d'ajustement par pression pour ajuster par pression un second élément de coin dans une partie entre l'élément de structure et le premier élément de coin en déplaçant le second élément de coin vers le bas tout en provoquant un contact coulissant d'une seconde surface inclinée obliquement vers le bas du second élément de coin avec la première surface inclinée.
