Abstract

L'invention concerne l'utilisation de polyuréthanne pur, non rempli, pour la formation de corps de remplissage de chambres, ainsi qu'un corps de remplissage de chambre proprement dit, convenant aublocage dans les chambres de rail de véhicules guidé sur voie, par coulée, sous forme de mousse rigide présentant une masse volumique de 40 à 160 kg/m3, dans un moule de couler dont la forme est adaptée exactement à celle de la chambre. Le polyuréthanne à coulée est ajusté et le moule de coulée est régulé thermiquement de façon telle que le corps de remplissage de chambre forme, aprèsla coulée, une peau mince. Il est particulièrement avantageux, selon l'invention, de produire le corps de remplissage dans le moule de coulée sous forme de corps de mousse façonné présentant desévidements ou une section constante d'une grande longueur correspondant à un multiple de la longueur d'installation, de mettre àla longueur, au moyen d'un outil de tronçonnage, ledit corps de remplissage, au niveau du point d'installation, et/ou de former par découpage des évidements pour les composants accouplés avec lesrails.
