Disclosed is a formwork panel that is made of an insulating material and incorporates a corrugated reinforcing metal core. Thanks to its reinforcing metal core that is corrugated, the panel is very strong and resistant to pressure whatever be the direction in which such pressure is exerted. Of course, since it is made of an insulating material, especially polyurethane foam, the panel is also heat and/or cold insulating and moisture resistant. Therefore, it can efficiently be used to build up permanent self-supporting formworks into which concrete can be cast to form insulated walls. Also disclosed in a process for the industrial manufacture of such panels in a continuous manner. In this process, the metal cores of the formwork panels a re manufactured in the form of a continuous metal core band. The metal core ban d is supplied onto a main conveyor. Simultaneously, a mixture of components th at react with each other to make an insulating foam is prepared and continuousl y injected at the inlet of the main conveyor. The foam that is being formed an d expands along the main conveyor, is compressed so as to form to a continuous main body band having a given height and given thickness. This continuous ma in body band incorporating the continuous metal core band. Last of all, the continuous main bodyband and the continuous metal core band incorporated therein are cut at the outlet of the main conveyor to obtain the requested panels. |
