Title
(EN) INSULATING FORMWORK PANEL AND MANUFACTURING SYSTEM AND PROCESS THEREFOR
(FR) PANNEAU DE COFFRAGE ISOLANT ET SYSTÈME ET PROCÉDÉ DE FABRICATION AFFÉRENTS
Abstract
(EN) The problem of rendering an insulating formwork panel both fire-resistant and easily cutable along its length is solved by manufacturing the panel in class A polyurethane and by embedding a fiberglass reinforcing mesh therein. According to illustrated embodiments, the insulating formwork panel further comprises at least one longitudinal rail that is secured to the panel so as to extend at least partially along a top edge thereof, wherein the bottom edge of the panel is configured to cooperate with the top edge of another similar concrete wall formwork panel for mounting thereto.
(FR) Le problème qui consiste à rendre un panneau de coffrage isolant à la fois résistant au feu et facile à couper sur sa longueur, est réglé par la fabrication du panneau en polyuréthane de classe A et par l'intégration dans celui-ci d'un maillage de renforcement de fibre de verre. Selon des modes de réalisation donnés à titre d'exemple, le panneau de coffrage isolant comprend, en outre, au moins un rail longitudinal qui est fixé au panneau de manière à s'étendre au moins partiellement le long d'un bord supérieur de celui-ci, le bord inférieur du panneau étant conçu pour coopérer avec le bord supérieur d'un autre panneau de coffrage de mur en béton similaire destiné à être monté sur celui-ci.
