Title (EN) SEALING JOINT FOR A LEAD-THROUGH FOR AT LEAST ONE LINE THROUGH A WALL OPENING
(FR) JOINT POUR UN PASSAGE PRATIQUE POUR AU MOINS UNE CONDUITE A TRAVERS UNE OUVERTURE MURALE
Abstract:
(EN) The sealing joint (1) fills in the lead-through the empty space between a line and the soffit of a wall opening. It forms at least one line housing (2) corresponding to the cross-section of the line and is sealed by compression in the wall opening on one hand against the line and on the other hand against the soffit of the wall opening. The sealing joint (1) is comprised of two parts (1.1, 1.2) separated from each other substantially in parallel to the axis (3) of the wall opening and assembled together by form-locking in the separating plane (9). One part (1.1) made of adjusted soft elastic rubber carries the sealing surface (4) close to the soffit of the wall opening, whereas the other part (1.2) made of hard elastic rubber adjusted by addition of flame protection substances and the like is inserted into a recess (5) of the soft elastic part (1.1) and is applied against part (1.1) in the recess (5) both axially and radially in the peripheral surface of an annular shoulder (6) delimiting outwardly the recess (5).
(FR) Le joint (1) remplit dans le passage l'espace vide entre une conduite et l'intrados d'une ouverture murale. Il forme au moins un logement de conduite (2) correspondant à la coupe transversale de la conduite et est étanche par compression dans l'ouverture murale d'une part contre la conduite, d'autre part contre l'intrados de l'ouverture murale. Le joint (1) se compose de deux parties (1.1, 1.2) séparées l'une de l'autre essentiellement parallèlement à l'axe (3) de l'ouverture murale et assemblées par liaison de forme dans la surface de séparation (9), dont une partie (1.1) formée de caoutchouc élastique souple ajousté porte la surface d'étanchéité (4) proche de l'intrados de l'ouverture murale, alors que l'autre partie (1.2) formée de caoutchouc élastique dur ajusté par addition de substances de protection contre les flammes et autres s'introduit dans un évidement (5) de la partie élastique souple (1.1) et s'applique contre cette partie (1.1) dans l'évidement (5) aussi bien axialement que radialement dans la surface périphérique d'un épaulement annulaire (6) délimitant l'évidement (5) vers l'extérieur.
