Tecnologia de mapeamento 3D para a otimização de projetos e processos de fachadas industrializadas EM ACM

Abstract

With increased stimulus to the industrialization of processes, in recent years, there has been a growing movement in the construction chain towards the search for non adhered façade systems in detriment to mortar adhered façades. This fact is due not only to a substantial reduction in problems associated with low technological control in the execution of coatings, but also in the speed of execution and installation at the construction site. In this context, the use of composite aluminum (ACM) facades, for example, is characterized by great acceptability due to greater constructive flexibility, reduced waste, light structure, ease of maintenance, in addition to enabling greater productivity. In contrast, one of the great challenges is the “in situ” measurement stage, whose acquisition of information still precedes manual collection methods and which can increase the degree of uncertainty of the values obtained. Thus, the goal of the work is to use a 3D mapping technology, more specifically, a Light Detection And Ranging - LIDAR, to promote agility and precision in data collection for the elaboration of the executive project with less rework. As a methodological proposal, two distinct evaluation moments are created. The first consisted of preparing a QFD to identify the main customer requirements. In a second moment, a theoretical review on the subject was sought, including the implementation of a beta version for a better understanding of the equipment's characteristics, resolution and operating limitations. Finally, planning for the implementation of the alpha version began with data collection with 3D mapping in an industrial site. The results demonstrated that the use of technology satisfactorily increases the productivity and precision of the executive project and reduces the loss rate of the ACM in the production of modular panels. Therefore, it is concluded that, after some procedural adjustments, the application of 3D mapping is viable and with a field for the development of the study evaluating the benefits generated in the other stages of manufacturing facades in ACM.
