Resumen
La presente memoria consta de dos grandes propósitos, basados en describir el funcionamiento y los procesos productivos de una empresa metal-mecánica en la formación de paneles metálicos y en determinar las consecuencias técnicas y económicas del uso de equipos formadores de paneles continuos metálicos para su aplicación "in situ" en cubiertas.
La metodología utilizada consistió en presentar referencias teóricas del funcionamiento de estas empresas junto a antecedentes con procedimientos, metodologías de instalación y un análisis del mercado nacional de modo de obtener una visión amplia y objetiva del rubro. El estudio está basado en un detallado estudio comparativo incluyendo procesos técnicos y costos asociados a ambos sistemas, el tradicionalmente usado y mediante el uso de la máquina de formado continuo, complementados con información entregada por ejecutivos del sector.
Las ventajas técnicas en el uso de esta máquina como son, su rapidez de formado, ausencia de flete de paneles, bajas pendientes cercanas al 2%, la absoluta estanqueidad por ausencia de fijaciones y uniones a la vista debido al largo continuo y a un emballetado hermético, justifican económicamente su aplicación en proyectos con volúmenes sobre los aproximadamente 5.000 m2. Bajo esta cantidad a instalar, su uso pasa por exigencias de carácter técnico y especificaciones especiales del proyecto.
En definitiva, ambos sistemas de formado ofrecen soluciones atractivas para el cliente y de calidad satisfactoria, sin embargo, la construcción actual demanda de tecnologías que agilicen aún más las obras disminuyendo los tiempos de ejecución, permitiendo a la máquina estudiada ofrecer ventajas comparativas indudables con respecto al sistema tradicional.
The present memory consists of two big purposes, based on describing the operation and the productive processes of a company metal-mechanics in the formation of metallic panels and in determining the technical and economic consequences of the use of teams formadores of metallic continuous panels for its application "in situ" in covered. The methodology used consisted on presenting theoretical references of the operation of these companies next to antecedents with procedures, installation methodologies and an analysis of the national market in way of obtaining a wide and objective vision of the item. The study this based on a detailed comparative study including technical processes and costs associated to both systems, the traditionally used and by means of the use of the roof panel machine, supplemented with information surrendered by executives of the sector. The technical advantages in the use of this machine like they are, their speed of having formed, absence of freight of panels, near pending drops to 2%, the absolute estanqueidad for absence of fixations and unions visible due to the long one continuous and to seam hermetic, they justify their application economically in projects with volumes on the approximately 5.000 m2. Under this quantity to install, their use goes by technical requirements of character and to special specifications of the project. In definitive, both systems of rollforming offer attractive solutions for the client and of satisfactory quality, however, the actually construction demand of technologies that speed it up but the works diminishing the times of execution, allowing to the studied machine to offer certain comparative advantages with the traditional system.
