Abstract

Une pince pour une forme de la présente invention comporte un connecteur de support couplé à une partie d'extrémité d'un boulon entretoise dont l'autre partie d'extrémité est couplée de façon détachable à un élément conique installé dans une forme interne, de manière à permettre l'utilisation d'une plaque d'isolation thermique en fixant temporairement celle-ci à une forme externe séparée, ou permettre qu'une plaque d'isolation thermique soit directement utilisée en tant que forme externe sans une forme externe, et étant donné que le boulon entretoise et le connecteur de support restent dans le béton durci, un traitement d'isolation thermique ultérieur comme dans les procédés conventionnels devient inutile, de manière à permettre la conduite plus simple de formation d'une paroi d'isolation thermique extérieure, et étant donné qu'une plaque d'isolation thermique relativement très épaisse est intégralement combinée au béton sur l'extérieur, non seulement un phénomène de pont thermique est efficacement évité mais également, un effet d'isolation thermique est nettement amélioré.
