Abstract

Un trou d'élément espacement elliptique, qui est plus long dans une direction le long de la direction longitudinale d'une poutre de support, est disposé sur une surface supérieure d'au moins un élément d'espacement d'une paire d'éléments d'espacement au niveau du côté de poutre de support. Dans la direction longitudinale de la poutre de support, une pluralité de trous de poutre est disposée le long de la direction longitudinale au niveau d'une partie d'extrémité sur le côté disposé sur la partie supérieure de l'au moins un élément d'espacement. L'élément d'espacement est fixé à la poutre de support avec un boulon qui passe à travers le trou d'élément d'espacement elliptique et un trou de poutre qui est disposé au niveau d'une position supérieure chevauchant le trou d'élément d'espacement elliptique.
