Uso da termografia infravermelha como ferramenta de inspeção predial especializada: análise das manifestações patológicas na fachada de um edifício localizado na cidade de São Luís, Maranhão

Abstract

Throughout Brazil, there has been a high incidence of cases of detachment of plaques, especially on building facades. Several cities and states are taking measures in order to minimize these problems, such as the drafting of laws that oblige the building inspection service to issue building inspection certificates, for example. But the processes used to carry out these inspections are often complicated and require high investments and time-consuming. As a result, the search for innovative methods that combine execution agility, flexibility and low cost are becoming more and more desirable within civil construction. Thus, this work aims to show, through theoretical

study and practical analysis, the efficiency of using infrared thermography as a non- destructive method to detect pathologies in building facades and not only the

detachment of the plates. Thermography, using its thermal variation, provides information necessary for the analysis results to be made faster and contribute to the cost of the service as a whole. The practical study of this work was carried out in a building in the city of São Luís do Maranhão, in which the objective was to identify the existing pathologies in the place, as well as to analyze the actions of the environment, as well as the materials that react to the circumstances of the environment and of the pathologies found. Thus, it can be concluded that infrared thermography is not only useful for the identification of hidden pathologies, but also proved to be effective for confirming visible pathologies through thermal differences, in addition to showing a vision of a possible implementation of this type of line of research, increasingly encouraging the use of thermography as a diagnostic engineering.
