CA 2210733

Sealing device for sealing a joint (2) formed between two sections (3, 4) to be concreted, whereby the sealing device is embedded in the sections (3, 4) so that it is positioned at a right angle to the abutting ends (5, 6) of the joint (2) opposite the concreted sections (3, 4), whereby the sealing device is formed as a thin-walled, strip-shaped joint rail (1) made of rigid plastic and its dimensional shape and its wall thickness are so dimensioned that it is self-supporting. The rigid plastic is preferably a thermoplastic plastic, in particular HDPE, which is dimensionally stable in a temperature range of -20°C to +80°C.

L'invention concerne un système d'étanchéité servant à rendre étanche un joint (2) réalisé entre deux sections de bétonnage (3, 4), ce système d'étanchéité étant inséré dans les sections de bétonnage (3, 4), de manière à se trouver perpendiculaire aux surfaces d'about (5, 6) du joint (2), formées de manière opposée sur les sections de bétonnage (3, 4). Le système d'étanchéité se présente sous forme de latte de jointoiement (1) à paroi mince, sous forme de bande, en plastique dur, et sa forme spatiale de même que l'épaisseur de sa paroi sont dimensionnées de manière à ce qu'il soit autoporteur. Le plastique dur est de préférence un thermoplastique, notamment du polyéthylène dur, indéformable sur une plage de températures allant de -20 à +80 DEG C.
