Abstract

SISTEMA DE CONSTRUCCION BASADO EN LA INTEGRACION DE ESPACIOS ELEMENTALES DELIMITADOS POR PIEZAS PREFABRICADAS. LOS ESPACIOS ELEMENTALES SE DEFINEN POR ANILLOS CONSTITUIDOS POR UN PERFIL DE SUELO, OTRO DE TECHO Y DOS PILARES VERTICALES. EL PERFIL DE SUELO CONSTITUIDO A PARTIR DE UN PERFIL PRINCIPAL DE U (4), INCLUYE OTROS PERFILES (7) PARA RECIBIR LOS PILARES VERTICALES QUE SE SUJETAN EN ESPARRAGOS Y TUERCAS, Y SE FIJAN AL SUELO POR MEDIOS ADECUADOS. LOS PILARES VERTICALES SE CONSTRUYEN CON DOS PERFILES EN C(12) ADOSADOS Y SOBRE SUS RAMAS LATERALES SE FIJAN LOS PANELES (13) CONSTITUTIVOS DE LOS TABIQUES QUE DEJAN UNA CAMARA INTERMEDIA PARA RELLENO DE MATERIAL AISLANTE. EL PERFIL DE TECHO SE CONSTRUYE A PARTIR DE UN PERFIL DE U(16), QUE TIENE ALAS LATERALES (17) PARA SOPORTAR LAS BANDEJAS QUE CONTIENEN EL MATERIAL DE TECHO, Y QUE MEDIANTE COLGANTES DE PLETINA (19, 20, 21) SE FIJA AL FORJADO SUPERIOR Y QUE A TRAVES DE UN NUEVO PERFIL (24) FIJADO EN SU PARTE INFERIOR SE ENCASTRA EN LOS PERFILESVERTICALES.
