Abstract(s)
A presente dissertação incide sobre o uso da termografia como método não destrutivo de verificação da existência de patologias nas edificações, nomeadamente o descolamento de revestimento de argamassa em paredes, o desplacamento de revestimentos cerâmicos e possibilidades de verificação de infiltrações e vazamento de água. Tem como motivação o preparo para inserção no mercado de consultoria. Logo, objetiva um estudo em profundidade de aplicações da termografia e radiometria no estudo das patologias aqui elencadas. O texto, que inicialmente emerge o conhecimento científico disponível, com ênfase na aplicabilidade prática de cada conceito, aborda os aspectos transversais da tecnologia da informação que permeiam a produção de arquivos digitais, o melhoramento de imagens e a produção de relatórios comerciais. Também versa sobre os aspectos técnicos da termografia, apresentando e discutindo as normas existentes no âmbito nacional e internacional. Aponta os principais fabricantes e evidencia as mais relevantes características técnicas dos equipamentos termográficos, inclusive, dando suporte ao processo decisório da seleção e escolha do equipamento mais adequado para o uso pretendido, evitando, assim, o emprego desnecessário de consideráveis recursos financeiros em equipamentos inadequados ou que excedem em muito a necessidade para o uso que deles se quer dar. Ensina os fundamentos de captura e interpretação de imagens termográficas, sugere boas práticas de operação, chama a atenção para as capacidades e limitações desses equipamentos e apresenta termogramas comentados de falhas engendradas para simular as patologias citadas como alvos deste estudo. Para a ciência, contribui com uma rica fonte de informação cujo conhecimento foi construído, em parte, experimentalmente, seguindo o rigor do método científico, no controlado ambiente de um laboratório, a partir de simulacros que em muito se aproximam do quotidiano de trabalho no campo de atuação da consultoria.
The present dissertation focuses on the use of thermography as a non-destructive method of verifying the existence of pathologies in buildings, namely the detachment of mortar lining on walls, the detachment of ceramic tiles and possibilities of verifying infiltration and water leakage. Its motivation is to prepare for insertion in the consulting market. Therefore, it aims at an in-depth study of applications of thermography and radiometry in the study of the pathologies listed here. The text, which emerges from the available scientific knowledge, with an emphasis on the practical applicability of each concept, addresses the transversal aspects of information technology that permeate the production of digital files, the improvement of images and the production of commercial reports. It also deals with the technical aspects of thermography, discussing the existing standards at the national and international levels. It points out the main manufacturers and highlights the most relevant technical characteristics of thermographic equipment, including, supporting the decision-making process of selecting and choosing the most appropriate equipment for the intended use, thus avoiding the unnecessary use of considerable financial resources in equipment. inadequate or that far exceed the need for the intended use. It teaches the fundamentals of capturing and interpreting thermographic images, good operating practices, draws attention to equipment limitations and limitations and presents commented thermograms of engineered failures to simulate the pathologies cited as targets of this study. For science, it contributes with a rich source of information whose knowledge was built, in part, experimentally, following the rigor of the scientific method, without environmental control of a laboratory, from simulations that are very close to the daily work in the field consulting activities.
