Abstract

L'invention concerne une unité de structure de paroi latérale de wagon (10), une paroi latérale (1) et un wagon de train. L'unité de structure de paroi latérale (10) comprend deux colonnes latérales longues (11), une pluralité de poutres longitudinales (12) et une pluralité de colonnes latérales courtes (13). Les colonnes latérales longues (11), les poutres longitudinales (12) et les colonnes latérales courtes (13) sont insérées et raccordées les unes aux autres pour former l'agencement du type grille de l'unité de structure (10). Une pluralité d'unités de structure (10) est fixement raccordée au moyen de poutres de renforcement (16), et un côté externe de l'unité de structure (10) est soudé à un panneau de paroi (17) au moyen d'un soudage par points par résistance pour former la paroi latérale de wagon (1). L'utilisation d'un nouveau procédé de soudage pour souder le panneau de paroi (17) à un côté externe de l'unité de structure (10) réduit la déformation du panneau de paroi externe (17) pendant l'installation et le soudage et améliore la planéité de la paroi latérale de wagon (1). De plus, la paroi latérale (1) ne forme pas de structure fermée après le soudage, ce qui permet de faciliter le soudage, de réduire la corrosion de la paroi latérale (1) et de mieux répondre aux exigences de l'utilisateur.
