Abstract

L'invention concerne un moule vertical pour produire un composant préfabriqué, comprenant des parties de moule latérales verticales, une partie de moule inférieure et une partie de moule supérieure qui entourent un espace pour couler le composant préfabriqué. La partie de moule inférieure et la partie de moule supérieure sont maintenues entre deux des parties de moule latérales verticales et une structure de fixation est disposée au sommet des parties de moule latérales verticales pour fixer deux des parties de moule latérales verticales. L'utilisation du moule vertical selon la présente invention offre un certain nombre d'avantages. Après la formation du composant préfabriqué et le retrait du moule, le composant préfabriqué peut être directement hissé et transporté, sans avoir besoin d'un processus d'érection. L'inconvénient associé à la coulée horizontale d'un panneau mural isolant dans lequel deux couches de béton doivent être coulées séparément peut être évité, ce qui améliore la qualité de production et l'efficacité de production. L'invention permet la coulée de structures tridimensionnelles ayant diverses formes complexes, telles que des formes en L, F ou E ou des formes de type échelle avec divers nombres de barres horizontales. En outre, chaque côté de la paroi préfabriquée est bien formé, sans avoir besoin d'un processus supplémentaire de raclage de celui-ci pour le lisser.
