Abstract

La invención se refiere a una viga de celosía, formada por varios perfiles metálicos paralelos entre sí (1,2,3) mantenidos juntos por estructuras de celosía (4) que se extienden perpendicularmente entre dichos perfiles, caracterizada porque tres perfiles huecos (1,2,3) se yuxtaponen a una viga de sección en triángulo isósceles, porque el perfil hueco (1) u los otros dos perfiles huecos (2, 3) están tienen cámaras huecas (9, 10, 11, 12, 13, 14) dispuestas simétricamente al vértice del triángulo, y para los dos otros, con simetría especular respecto del plano que se extiende en el medio, entre las ramas de iguales longitudes, y porque al menos una parte de las cámaras de todos los perfiles huecos está dotada, en la pared exterior de ésta, de una ranura (15) abierta hacia el exterior. Gracias a esta disposición, la viga de celosía puede disponer de elementos de conexión de los sistemas conocidos de construcción para ferias y exposiciones. También se pueden disponer elementos suplementarios o placas de decoración (17) de manera sencilla, de manera que la viga de celosía forme un elemento de construcción estético.
