Abstract

Selon les procédés connus de protection de joints d'éléments préfabriqués en béton conçus comme éléments de paroi double ou éléments de paroi en dur, seuls des composants de protection de joints en une étape sont employés, de façon multiple en tant que minces bandes d'étanchéité collées par l'extérieur sur les joints vifs. Selon le procédé pour un système de protection de joints en plusieurs étapes pour des éléments de paroi (1, 1a) composés d'éléments préfabriqués en béton, la première étape consiste à mouler un profilé de bande d'étanchéité (11, 11a, 11b) directement sur le joint vif (5, 5a), celui-ci étant réalisé avec un profilé de protection de joints (6, 6a, 6b) et étant moulé jointif sur le joint vif (5, 5a) de façon à le chevaucher. Dans la deuxième étape, les profilés de protection de joints (6, 6a, 6b) forment, avec les barrières contre l'humidité (12) moulées en forme de clavette sur les bandes latérales, une protection amont pour le joint vif (5, 5a) situé en dessous. Le profilé de protection de joints (6, 6a, 6b) protège en plus le profilé de bande d'étanchéité (11, 11a, 11b) moulé de façon spécifique aux joints, au moyen d'une enveloppe plastique élastique solide. Dans la troisième étape, un profilé de surface de protection de joints (13, 13a, 13b) amont est appliqué sur le profilé de protection de joints (6, 6a, 6b), des barrières contre l'humidité (12) en forme de clavette étant créées des deux côtés du profilé de protection de joints (6, 6a, 6b) entouré de celles-ci. Le profilé de surface de protection de joints (13, 13a, 13b) est avantageux pour des terrains fortement exposés à l'humidité, par exemple aux nappes phréatiques. Ainsi, une protection de joints en trois étapes est créée pour les joints vifs (5, 5a) des éléments de paroi double ou des éléments de paroi en dur (1, 1a). L'invention permet une protection en plusieurs étapes des joints vifs (5, 5a) d'éléments préfabriqués en béton conçus comme éléments de paroi double (1) ou éléments de paroi en dur (1a), sûre, économique et fiable contre l'humidité du sol, notamment contre les nappes phréatiques et les effets mécaniques. Le procédé est notamment destiné à des caves et peut également être employé pour la protection de joints d'autres parties d'immeubles souterraines et pour des contenants composés d'éléments préfabriqués en béton.
