Abstract

La présente invention a trait à une crémaillère pour installation de structure qui inclut des pannes (15), chaque panne étant formée en raccordant une pluralité d’éléments de panne (151, 152) qui sont dotés chacun d’une paire de plaques latérales s’étendant dans la même direction et qui se présentent chacun sous une forme dans laquelle un bord de l’une des deux plaques latérales qui s’étend dans ladite direction a été raccordé au moyen d’une plaque principale à un bord de l’autre plaque latérale qui s’étend dans ladite direction. Les éléments de panne raccordés (151, 152) se présentent sous une forme dans laquelle au moins une extrémité de la plaque principale ou des plaques latérales a été partiellement découpée. Une extrémité des plaques latérales de l’un des éléments de panne (151, 152) est raccordée à une extrémité des plaques latérales de l’autre élément de panne de sorte que la première extrémité chevauche la surface intérieure ou extérieure de la dernière extrémité.
