Abstract

La présente invention se rapporte à un raidisseur pour permettre un couplage par une charnière à pivot et à une porte coupe-feu pour laquelle un soudage n'est pas nécessaire ainsi qu'à un procédé de fabrication de cette dernière et, de façon plus précise, l'invention permet : que des parties d'extrémité supérieure et inférieure d'un panneau avant et d'un panneau arrière soient pliées de telle sorte que les parties d'extrémité supérieure et inférieure fassent saillie et soient courbées ; et que les parties pliées dudit panneau avant et dudit panneau arrière soient orientées l'une vers l'autre, les parties pliées étant partiellement recouvertes par de multiples étages de telle sorte qu'un raidisseur distinct et un travail de meulage après une opération de soudage ne soient pas nécessaires lors d'un couplage à une charnière à pivot normale, ce qui permet de procurer une certaine commodité, de réduire la notion d'esthétique, d'augmenter l'élégance de conception et, en outre, de présenter le même effet de résistance au feu que les portes coupe-feu existantes et, en même temps, d'obtenir une meilleure efficacité économique par réduction des coûts de fabrication.
