ABSTRACT:
The invention relates to a factory prefabrication method for hollow panels for the on-site erection of insulated constructions.
This method employs a three-dimensional framework 1 composed of thrust bars arranged in two parallel planes and of link bars linking the former. The method consists in placing said framework in a mold 13 containing a pulverulent material 16 wherein the framework is embedded by part of its thickness, in molding an insulating synthetic material 4 in the empty part of the mold so as to embed the visible parts of the framework 1, in placing above the mold a form sheet 2 so that the insulating material shall make contact with it and adhere to it during hardening, and after this hardening, in extracting the pulverulent material and in ejecting the obtained panel. The panel so manufactured can be provided after ejection with a second form sheet opposite the first.
