Abstract

L'invention concerne un écran de type shoji à carreaux multiples qui peut maintenir la position du butyle servant d'élément d'étanchéité et créer un joint entre un élément de connexion d'entretoise et une entretoise. En outre, l'invention concerne un écran de type shoji à carreaux multiples qui peut supprimer le gonflement d'un premier cadre provoqué par une augmentation de la pression interne dans une couche creuse. Ledit écran de type shoji à carreaux multiples comprend : une clavette d'angle (150) qui comprend une pluralité de parties insérées (154) disposées en forme de L de façon à être insérées dans une entretoise (128), et une partie en saillie formée entre une partie principale (152) et une partie insérée (154); et un élément d'étanchéité (159) qui est disposé entre l'entretoise (128) et la partie insérée (154) venant en butée contre la clavette d'angle (150) et disposé de manière à reposer sur le côté opposé d'une couche creuse divisée (130) par rapport à la partie en saillie (157). Ainsi, l'élément d'étanchéité (159) peut être maintenu dans une position déterminée par la partie en saillie (157).
