Utilizando paredes de concreto moldadas "in loco" - estudo de caso

Abstract

This study addresses the massive walls of concrete, construction technology, its standardized designs, high degree of repeatability and simultaneous implementation structure and sealing. In this study the aspects of high productivity have been exposed, as well as large-scale production, reducing costs with labor and minimizing the runtime errors. In this paper the main aspects of the construction process were also treated, their advantages over conventional processes, standardization and the care with the modulation and the choice of formwork set, considering the wide range of the latter in the civil construction market. It is attempted to answer: What are the main precautions to be taken during assembly of molds during the steps of the construction of the walls of reinforced concrete, molded "in loco"? To answer this question the purpose of the study was to describe, through a case study along the lines of a public housing construction, what precautions should be taken with the assembly of molds? The site which was the Object of this research was located in the metropolitan region of Belo Horizonte-MG and was observed in this executive stage of the construction of a residential building with 5 floors using the formwork molded concrete walls method. Based on this study it was concluded that the construction system of molded concrete walls "in loco" was quite distinct from conventional construction processes, but easy to perform, thereby generating a increase in productivity in relation to the project runtime. This, and the use of accelerated curing of concrete, resulting in a faster construction time and fewer finishing steps. Considering all the benefits of that building process, and the current state of the construction market, one can predict a large increase in their use, especially after the development of ISO 16055 (2012) governing its use.
