Resumen
La construcciĆ³n ha experimentado un fuerte crecimiento en los Ćŗltimos aƱos por lo que
se han debido destinar recursos tecnolĆ³gicos para mejorar los rendimientos sin afectar
la calidad de los productos.
Dentro de los costos de la construcciĆ³n, un factor altamente incidente es el sistema de
moldajes. Estos sistemas son muy variados y son clasificados segĆŗn su material y su
peso. Este estudio estƔ enfocado a los moldajes semi pesados y metƔlicos que son
frecuentemente utilizados en la construcciĆ³n en Chile.
El moldaje Outinord pertenece a la clasificaciĆ³n de moldajes semi pesados y metĆ”licos
modulares, consiste en un encofrado en forma de tĆŗnel que permite el hormigonado
simultƔneo de muros y losas en corto tiempo. En Chile no se utiliza masivamente este
sistema ya que se prefiere la utilizaciĆ³n de paneles dimensionados para el ensamble
del moldaje segĆŗn el elemento a hormigonar, a pesar de que este sistema necesita
mayor tiempo para su armado este tipo de moldaje, el Efco, paneles dimensionados de
uso manual. La principal diferencia entre estas alternativas de moldajes es el tiempo
necesario para las faenas.
Se realizĆ³ una comparaciĆ³n de estas dos alternativas de moldajes, Outinord y Efco
considerando sus antecedentes tƩcnicos, rendimientos y costos de mano de obra y
otros elementos involucrados es su utilizaciĆ³n. Esta comparaciĆ³n permite advertir que
aunque los costos de la adquisiciĆ³n y mano de obra de los moldaje sea menor para
Efco a medida del avance de la obra la situaciĆ³n se revierte debido a que Outinord tiene
un mejor rendimiento llegando a valor que difieren en la cuadrilla de moldaje por
pequeƱas cantidades. La gran diferencia de la marca Outinord reside en los gastos
generales de la obra, ya que como su rendimiento es mejor la obra disminuye su tiempo
de ejecuciĆ³n.
The construction has experimented a strong increase in the last years; it demanded destiny technological resources to improve the efficiency without affect the quality of the products. If we talk about the cost of the construction, a factor that incised in a high rate is the system of framework. Those systems are very varied and they are classified according to the material and the weight. This investigation is focus on the semi weighted and metallic framework which are frequently used in the Chilean constructions. The Outinord framework belong to the classification of semi weighted and metallic modular frameworks, it consist in one mold with a shape similar to a tunnel, it allow the simultaneous concreted of walls and flagstones in a short time. In Chile this system is not used massively, because we prefer to use the dimensional panels to assemble frameworks according to the thing that will be concreted, although that system need more time to be armed. We can analyze other kinds of frameworks, the Efco, dimensional panels of manual use. The main different between the alternatives of frameworks are the time required to made the job. The comparison between those two alternatives of frameworks, Outinord and Efco, considering their technical antecedents, efficiency and costs of workers and other elements related to the utilization showed that although the acquiring costs and workers of the frameworks are cheaper on Efco, in the following time of the works the situation changes and Outinord prove that It has a better efficiency arriving to a value that differ in the quadrilles of framework by little quantities. The great different of outinord reside in the general costs of the job, because his efficiency is better and the time of work decrease during the execution time.
