Title
(EN) IMPROVEMENT IN A SEALING ELEMENT FOR EXPANSION JOINTS
(FR) PERFECTIONNEMENT D'UN ÉLÉMENT D'ÉTANCHÉITÉ DESTINÉ À DES JOINTS DE DILATATION
Abstract
(EN)
The sealing element (E) comprises: a sealing profile (20), having two lateral flanges (21) provided with an outer edge (21a) and an inner edge (21b) and joined by a central portion (22) to be lodged in an expansion joint (11) formed between two structure portions (10); and a reinforcing portion (30), in the form a flexible mat. Each lateral flange (21) has an upper portion (23) incorporated to the central portion (22), in the region of the inner edge (21b), and, a lower portion (24), which defines a spacing (D) with the upper portion (23) and which is incorporated to the latter, in the region of the outer edge (21a), and to be affixed in one of the structure portions (10). The reinforcing portion (30) has lateral portions (31) which are lodged and glued in the respective spacings (D), and a median portion (32) disposed around the central portion (22) of the sealing profile (20), downstream of the latter.
(FR)
L'invention se rapporte à un élément d'étanchéité (E) qui comprend : un profil d'étanchéité (20), possédant deux brides latérales (21) dotées d'un bord extérieur (21a) et d'un bord intérieur (21b) et jointes par une partie centrale (22) à loger dans un joint d'expansion (11) formé entre deux parties de la structure (10); et une partie de renfort (30), sous la forme d'un matelas souple. Chaque bride latérale (21) possède une partie supérieure (23) incorporée dans la partie centrale (22), dans la région du bord intérieur (21b), et une partie inférieure (24), qui définit un espacement (D) avec la partie supérieure (23) et qui est incorporée à cette dernière, dans la région du bord extérieur (21a), et à apposer dans une des parties de structure (10). La partie de renfort (30) possède des parties latérales (31) qui sont logées et collées dans les espacements respectifs (D), et une partie médiane (32) disposée autour de la partie centrale (22) du profil d'étanchéité (20), en aval de ce dernier.
